 上記のような2枠仕様の刈り取り搬送構造を採用した小型のコンバインにおいては、所定の転倒角を確保するために広く設定されている左右のクローラの轍間距離よりも刈取搬送部の作業幅が狭くなる。そのため、車体の左右両外側方に未刈りの作物が存在する中割り作業が難しくなる。
 そこで、小型コンバインの刈り取り搬送構造においては、搭乗運転部から離れる側の引起枠を1条用に構成し、かつ、搭乗運転部側の引起枠を最大2条の作物穀稈の引き起こしが可能な2条用に構成することにより、刈取搬送部を作業幅の広い2枠3条刈り仕様に構成するとともに、この刈取搬送部を、車体の略左右中央に位置させて車体の左右幅内(クローラの轍間)に存在する3条の作物を収穫する中割り作業位置と、この中割り作業位置よりも搭乗運転部から離れる側に変位させて搭乗運転部から離れる側に存在する2条の作物を収穫する回り刈り作業位置とにわたって、走行車体に対して横スライド可能に装備することにより、中割りと回り刈りの双方の作業走行を良好に行えるようにしたものがある(例えば特許文献1参照)。
[1] Among the combines, there is a small combine that adopts a two-frame mowing and conveying structure. In this combine, a cutting and conveying unit is connected to one of the left and right sides of the traveling vehicle body, a riding operation unit is formed on the other left and right side of the traveling vehicle body, and a threshing device is disposed at a position behind the cutting and conveying unit in the traveling vehicle body. And a pair of left and right pulling frames are formed by arranging three weeding members and a pair of right and left pulling devices in the cutting and conveying section so that the pulling device is positioned between two adjacent weeding members. A squeeze transport device that squeezes and transports the crop culm harvested by the reaping device of the reaping transport unit to each of the left and right pulling frames to the cereal passing part formed between the left and right pulling frames. The cutting and conveying unit includes a supply and conveying device that conveys the culm of the crop conveyed to the cereal passing unit by the left and right scraping and conveying devices to the threshing device.
In a small combine that adopts the two-frame specification mowing and conveying structure as described above, the working width of the mowing and conveying unit is larger than the distance between the left and right crawlers that is set widely in order to secure a predetermined fall angle. Narrow. For this reason, it is difficult to perform the split operation in which uncut crops exist on the left and right outer sides of the vehicle body.
Therefore, in the harvesting and transporting structure of the small combine, the pulling frame on the side away from the boarding operation part is configured for one line, and the pulling frame on the boarding operation part side can cause a maximum of two crop culms. By constructing for two lines, the cutting and conveying part is configured to have a two-frame and three-line cutting specification with a wide working width, and this cutting and conveying part is positioned substantially at the center of the left and right sides of the vehicle body (within the left and right widths of the vehicle body). The middle split work position for harvesting the three crops in the furrow) and the two crops present on the side farther from the boarding operation section by shifting to the side farther from the boarding operation section than the middle work position There is one that can perform both the middle split and the swivel work well by being equipped so as to be slidable laterally with respect to the traveling vehicle body over the swivel cutting work position (see, for example, Patent Document 1). ).
[2]コンバインの中には、走行車体の左右一方側に刈取搬送部を連結し、前記走行車体の左右他方側に搭乗運転部を形成し、前記走行車体における前記刈取搬送部の後方の位置に脱穀装置を配備し、前記刈取搬送部と前記脱穀装置との間に、前記刈取搬送部の供給搬送装置により搬送した穀稈の穂先側を前記脱穀装置の供給口に案内する穂先ガイドを配備したものがある。
 上記のようなコンバインの車体構造では、刈取搬送部の前端に備えた分草具と車体の前方に位置する作物穀稈との位置関係などを搭乗運転部から視認する際に、搭乗運転部からの視界が、刈取搬送部の前部に立設した引起装置により遮られることを防止するために、刈取搬送部をできるだけ車体の後方寄りに配置して、刈取搬送部の前端位置を搭乗運転部の前端位置に車体前後方向において近づけるようにしてある。
 そのため、従来のコンバインの車体構造においては、脱穀装置の供給口が搭乗運転部に備えた運転座席よりも車体後方側に位置するようになっていた(例えば特許文献2参照)。

[1]背景技術[1]に対応する課題は以下の通りである。
 上記の構成によると、走行車体に対する刈取搬送部の横スライドを可能にするための複雑な構造を要することになる。そのため、刈り取り搬送構造が大掛かりで複雑になるとともに刈り取り搬送構造に要するコストが嵩むことになる。
 本発明の目的は、刈り取り搬送構造の複雑化やコストの高騰を招くことなく、中割りと回り刈りの双方の作業走行を良好に行えるようにすることにある。
[1] Issues corresponding to the background art [1] are as follows.
According to said structure, the complicated structure for enabling horizontal cutting of the cutting conveyance part with respect to a traveling vehicle body is needed. Therefore, the cutting and conveying structure becomes large and complicated, and the cost required for the cutting and conveying structure increases.
An object of the present invention is to make it possible to satisfactorily perform both the middle-cutting and the turning-cutting work without complicating the cutting and conveying structure and increasing the cost.
[2]背景技術[2]に対応する課題は以下の通りである。
 供給搬送装置は、刈り取った穀稈の株元側を挟持搬送する株元挟持搬送機構と、その穀稈の穂先側を係止搬送する穂先係止搬送機構とを上下に配置して、穀稈を、刈り取り直後の起立姿勢から脱穀処理用の横倒れ姿勢に姿勢変更しながら脱穀装置に向けて搬送するように構成してある。脱穀装置は、その車体外方側の左右一側部に、供給搬送装置が搬送した穀稈の株元側を挟持搬送する挟持搬送機構を備え、この挟持搬送により、穀稈の穂先側を脱穀装置の供給口から脱穀装置の内部に供給するように構成してある。穂先ガイドは、その挟持搬送機構が搬送する穀稈の穂先側を脱穀装置の供給口に案内する。
 つまり、刈取搬送部においては、供給搬送装置によって穀稈の株元側とともに穂先側を強制搬送しているのであるが、脱穀装置においては、挟持搬送機構によって穀稈の株元側のみを強制搬送するだけとなる。そのため、挟持搬送機構による穀稈の搬送中に穀稈の株元側に対して穂先側が遅れて搬送される穂先遅れを招くことがある。この穂先遅れが発生すると、穀稈の搬送姿勢が、穀稈の搬送や脱穀処理に適した姿勢から外れた姿勢になりやすくなり、これにより、穂先遅れに起因した搬送詰まりや脱穀処理中の穀稈が挟持搬送機構の挟持位置近くから分断される穂切れなどを誘発することがある。
 ちなみに、穂切れが発生した場合には、脱穀処理後の処理物に含まれる切れワラやワラ屑の量が多くなり、脱穀処理後の選別処理における選別効率や選別精度の低下を招くことになる。
 搬送詰まりや穂切れなどの誘発を確実に回避するための手段としては、供給搬送装置の搬送終端部と脱穀装置の供給口との間において穀稈の穂先側を強制搬送する穂先搬送機構を装備することが考えられる。しかしながら、この場合には、構成の複雑化やコストの高騰を招く上に、手刈りした穀稈を脱穀装置に手作業で供給する枕扱ぎ作業が行いにくくなる。
 また、運転者が、供給搬送装置の搬送終端部と脱穀装置の供給口との間において挟持搬送機構により搬送する穀稈の搬送姿勢を監視し、穂先遅れが発生した場合に、その穀稈の穂先側を手で脱穀装置側に掻き寄せることにより穂先遅れを解消することも考えられる。しかしながら、前述したように、従来のコンバインの車体構造においては、脱穀装置の供給口が搭乗運転部に備えた運転座席よりも車体後方側に位置することから、挟持搬送機構により搬送する穀稈の搬送姿勢を監視するためには、作業走行中に車体の前方から完全に目を逸らす必要があり、しかも、穂先遅れが発生した場合には、車体の前方から完全に目を逸らす時間が長くなる虞がある。このように、作業走行中に車体の前方から完全に目を逸らしてしまうと、収穫する作物に対する適正位置から車体位置が外れる虞が高くなる。
 つまり、従来のコンバインでは、車体の構造上、運転者が、挟持搬送機構による穀稈の搬送姿勢を監視し、穂先遅れが発生した場合に手作業で穂先遅れを解消する場合には、作業走行中に車体の前方から完全に目を逸らすことによる作業精度の低下などを招きやすくなる。
 本発明の目的は、コンバインの車体構造に簡単な改良を加えることにより、供給搬送装置の搬送終端部と脱穀装置の供給口との間での穂先遅れに起因した搬送詰まりや穂切れなどの誘発を回避することにある。
 
[2] Issues corresponding to the background art [2] are as follows.
The feeding and conveying device is configured by arranging a stock holding and transporting mechanism for holding and transporting the stock side of the harvested corn straw, and a tip locking transport mechanism for latching and transporting the head side of the grain cocoon, Are conveyed toward the threshing device while changing the posture from the standing posture immediately after cutting to the sideways posture for threshing treatment. The threshing device is provided with a pinch transport mechanism for pinching and transporting the stock side of the grain straw transported by the supply transport device on the left and right sides of the outer side of the vehicle body. It is comprised so that it may supply to the inside of a threshing apparatus from the supply port of an apparatus. The tip guide guides the tip side of the cereal cocoon conveyed by the holding and conveying mechanism to the supply port of the threshing apparatus.
In other words, in the harvesting and conveying unit, the tip side is forcibly conveyed along with the stock side of the grain straw by the supply and transportation device, but in the threshing device, only the stock side of the grain seed is forcibly conveyed by the sandwiching and transporting mechanism. Just do it. For this reason, there is a case in which the tip of the head is delayed with respect to the stock side of the grain during the transportation of the grain by the holding and transport mechanism. When this tip delay occurs, the posture of the grain pods tends to deviate from the posture suitable for the cereal conveyance and threshing treatment, thereby causing the clogging due to the delay of the tip and the grain being threshed. In some cases, the cocoon breaks off the vicinity of the nipping position of the nipping / conveying mechanism.
By the way, when a spike occurs, the amount of cut straw and bran waste contained in the processed product after the threshing process increases, and the sorting efficiency and sorting accuracy in the sorting process after the threshing process are reduced. .
Equipped with a tip transport mechanism that forcibly transports the tip side of the cereal between the transport terminal end of the feed transport device and the supply port of the threshing device as a means to reliably avoid the occurrence of transport clogging or cutting of the ear It is possible to do. However, in this case, the configuration is complicated and the cost is increased, and it is difficult to manually perform the pillow handling operation of manually supplying the harvested cereal to the threshing apparatus.
In addition, when the driver monitors the posture of the cereals conveyed by the sandwiching and conveying mechanism between the conveying terminal end of the supply conveying device and the supply port of the threshing device, It is also conceivable to eliminate the tip delay by scraping the tip side to the threshing device side by hand. However, as described above, in the conventional combine vehicle body structure, the supply port of the threshing device is located on the rear side of the vehicle body with respect to the driver seat provided in the boarding operation unit. In order to monitor the transport posture, it is necessary to look completely away from the front of the car body during work travel. In addition, if a head delay occurs, it takes longer to completely look away from the front of the car body. There is a fear. In this way, if the user completely distracts from the front of the vehicle body during work traveling, the vehicle body position is likely to deviate from the appropriate position for the crop to be harvested.
In other words, in the conventional combine, the driver monitors the posture of the cereals transported by the pinch transport mechanism due to the structure of the vehicle body, and if the head delay is caused manually, It becomes easy to invite the fall of the work precision etc. by looking away from the front of the body completely.
The object of the present invention is to induce a clogging of a conveyance or a piece of a spike due to a delay in a tip between a conveyance terminal end of a supply conveyance device and a supply port of a threshing device by adding a simple improvement to the body structure of the combine. Is to avoid.

 前記搭乗運転部に備えた運転座席の真横に前記供給口が位置するように構成してあることを特徴とするコンバイン。
[2] Means for solving the problem [2] are as follows.
A cutting and conveying unit is connected to one of the left and right sides of the traveling vehicle body, a boarding operation unit is formed on the other side of the traveling vehicle body, and a threshing device is arranged at a position behind the cutting and conveying unit in the traveling vehicle body,

 この特徴構成によると、供給搬送装置の搬送終端部と脱穀装置の供給口との間が、運転座席の真横よりも車体前方側に位置するようになる。
 そのため、作業走行中においては、収穫する作物に対する適正位置から車体位置が外れないように車体の前方を目視しながらも、そのときの視界内に、供給搬送装置の搬送終端部と脱穀装置の供給口との間を入れることが可能になる。つまり、車体の前方を目視しながらも、供給搬送装置の搬送終端部と脱穀装置の供給口との間において挟持搬送機構が搬送する穀稈の搬送姿勢を監視することができる。
 また逆に、供給搬送装置の搬送終端部と脱穀装置の供給口との間において挟持搬送機構が搬送する穀稈の搬送姿勢をより確実に把握するために、供給搬送装置の搬送終端部と脱穀装置の供給口との間を直視する場合には、そのときの視界内に車体前方の光景を入れることが可能になる。つまり、供給搬送装置の搬送終端部と脱穀装置の供給口との間を直視した場合であっても、収穫する作物に対する適正位置から車体位置が外れる虞を回避しやすくなる。
 そして、供給搬送装置の搬送終端部と脱穀装置の供給口との間において穂先遅れが発生した場合には、その穀稈の穂先側を手で脱穀装置側に掻き寄せることにより、穂先遅れを簡単に解消することができる。

According to this characteristic configuration, the space between the conveyance terminal portion of the supply conveyance device and the supply port of the threshing device is located on the front side of the vehicle body rather than just beside the driver seat.
For this reason, during work travel, while viewing the front of the vehicle body so that the vehicle body position does not deviate from the appropriate position for the crop to be harvested, the supply terminal of the supply conveyance device and the supply of the threshing device are within the field of view at that time. It becomes possible to put between the mouth. That is, it is possible to monitor the conveying posture of the cereals conveyed by the sandwiching and conveying mechanism between the conveying terminal end of the supply conveying device and the supply port of the threshing device while viewing the front of the vehicle body.
On the other hand, in order to more reliably grasp the transport posture of the corn straw transported by the sandwiching transport mechanism between the transport terminal portion of the supply transport device and the supply port of the threshing device, the transport terminal portion of the supply transport device and the threshing When looking directly into the supply port of the apparatus, it is possible to put a scene in front of the vehicle body in the field of view at that time. That is, it is easy to avoid the possibility that the position of the vehicle body deviates from the appropriate position for the crop to be harvested even when looking directly between the conveyance terminal portion of the supply conveyance device and the supply port of the threshing device.
And, when a tip delay occurs between the conveyance terminal end of the supply transport device and the supply port of the threshing device, the tip delay can be easily reduced by scraping the tip side of the culm to the threshing device side by hand. Can be resolved.
Therefore, the tip generated between the conveying terminal portion of the feeding and conveying device and the feeding port of the threshing device can be simply improved by arranging and setting so that the feeding port of the threshing device is located beside the driver seat. It is possible to avoid the occurrence of clogging of conveyance or cutting of ears due to delay.
 一好適実施形態では、前記穂先ガイドの案内面の高さ位置と前記運転座席の座面の高さ位置とが同じまたは略同じになるように構成してあることを特徴とする。 In a preferred embodiment, the height position of the guide surface of the tip guide and the height position of the seat surface of the driver seat are configured to be the same or substantially the same.
 この特徴構成によると、従来の車体構造では運転座席の底面よりも低い位置に位置するように設定していた穂先ガイドの案内面が、運転座席に座った運転者の視界に入りやすく手の届きやすい位置に位置するようになる。
 そのため、供給搬送装置の搬送終端部と脱穀装置の供給口との間において挟持搬送機構が搬送する穀稈の搬送姿勢の監視が行いやすくなる。また、供給搬送装置の搬送終端部と脱穀装置の供給口との間において穂先遅れが発生した場合の前述した手作業による穂先遅れの修正が行いやすくなる。
 従って、供給搬送装置の搬送終端部と脱穀装置の供給口との間で発生する穂先遅れに起因した搬送詰まりや穂切れなどの誘発をより簡単かつ確実に回避することができる。
According to this characteristic configuration, the guide surface of the tip guide, which was set to be positioned lower than the bottom surface of the driver's seat in the conventional vehicle body structure, can easily reach the driver's field of view sitting in the driver's seat. It comes to be located in an easy position.
Therefore, it becomes easy to monitor the conveying posture of the corn straw conveyed by the nipping and conveying mechanism between the conveying terminal portion of the supply conveying device and the supply port of the threshing device. In addition, it becomes easy to correct the tip delay due to the above-described manual operation when a tip delay occurs between the conveyance terminal end of the supply transport device and the supply port of the threshing device.

 一好適実施形態では、前記搭乗運転部における車体内方側の左右一側部にサイドパネルを立設し、
 前記サイドパネルの上面の高さ位置が、前記穂先ガイドの案内面の高さ位置および前記運転座席の座面の高さ位置と同じまたは略同じになるように構成してあることを特徴とする。
In one preferred embodiment, a side panel is erected on the left and right side portions on the vehicle body inward side in the boarding operation portion,
The height position of the upper surface of the side panel is configured to be the same or substantially the same as the height position of the guide surface of the tip guide and the height position of the seat surface of the driver seat. .
 この特徴構成によると、運転座席と穂先ガイドとの間にサイドパネルを立設した場合に、そのサイドパネルによって穂先ガイドに対する視界が制限されるのを防止することができる。
 従って、サイドパネルの装備にかかわらず、供給搬送装置の搬送終端部と脱穀装置の供給口との間で発生する穂先遅れに起因した搬送詰まりや穂切れなどの誘発を回避することができる。
According to this characteristic configuration, when a side panel is erected between the driver's seat and the tip guide, it is possible to prevent the visibility of the tip guide from being limited by the side panel.
Therefore, regardless of the equipment of the side panel, it is possible to avoid the occurrence of clogging of conveyance or cutting of the ears due to the delay of the tip generated between the conveyance terminal portion of the supply conveyance device and the supply port of the threshing device.
  一好適実施形態では、前記搭乗運転部における刈取搬送部側の前端部に、前記供給搬送装置の搬送始端部が入り込むことを許容する凹部を形成し、
 前記供給搬送装置を、前記搬送始端部が前記凹部に入り込むように、その車体前後方向に対する車体左右方向への傾斜角を大きくしてあることを特徴とする。
In one preferred embodiment, a recess that allows a transfer start end of the supply transfer device to enter the front end of the boarding operation unit on the cutting transfer unit side is formed,
The supply / conveyance device is characterized in that an inclination angle in the lateral direction of the vehicle body with respect to the longitudinal direction of the vehicle body is increased so that the conveyance start end portion enters the recess.
 この特徴構成によると、搭乗運転部に凹部を形成しない場合に比較して、供給搬送装置の搬送始端部側を搭乗運転部に近づけることができ、供給搬送装置の車体前後方向での長さを短くすることができる。
 これにより、運転座席の真横に脱穀装置の供給口を位置させるのに伴って、供給搬送装置の搬送終端部を車体前方側に変位させる必要が生じても、その変位に伴って刈取搬送部の全体が車体前方側に変位することを防止することができる。
 その結果、刈取搬送部の全体が車体前方側に変位することに起因して、コンバイン全体としての全長が長くなる、あるいは、刈取搬送部の前端位置が搭乗運転部の前端位置から車体前方側に離れることにより、刈取搬送部の前端に備えた分草具と車体の前方に位置する作物穀稈との位置関係などを搭乗運転部から視認する際に、搭乗運転部からの視界が、刈取搬送部の前部に立設した引起装置により遮られる、といった不都合が発生することを防止することができる。
 従って、コンバイン全体としての全長が長くなることに起因した旋回性の低下や、搭乗運転部からの視界が引起装置により遮られることに起因した作業性の低下などを回避しながら、供給搬送装置の搬送終端部と脱穀装置の供給口との間で発生する穂先遅れに起因した搬送詰まりや穂切れなどの誘発を回避することができる。
According to this characteristic configuration, compared to the case where no recess is formed in the boarding operation unit, the conveyance start end side of the supply conveyance device can be brought closer to the boarding operation unit, and the length of the supply conveyance device in the longitudinal direction of the vehicle body can be increased. Can be shortened.
As a result, even if it is necessary to displace the transport terminal portion of the supply and transport device to the front side of the vehicle body as the supply port of the threshing device is positioned directly beside the driver's seat, It is possible to prevent the whole from being displaced forward of the vehicle body.

 左側の引起装置22Aは、その入力軸53Aが一対のベベルギヤ63を介して左伝動軸46と連動する。この連動により、その無端チェーン58Aが正面視において右回りに回動する。この回動により、各引起爪59Aが、第1ガイドレール61Aにより下向きの作用姿勢に保持される領域Aa1では、刈取搬送部3の左端側から左右中央側に向けて移動し、この移動により、左分草部材21Aと中分草部材21Cとの間に導入された最大2条の作物Cの穀稈を刈取搬送部3の左右中央側に向けて掻き込み案内する。また、第2ガイドレール62Aにより横向きの作用姿勢に保持される領域Aa2では、引起ケース52Aの下端部から上部に向けて移動し、この移動により、掻き込み案内後の作物Cの穀稈を引き起こす。 The left pulling device 22A has its input shaft 53A interlocked with the left transmission shaft 46 via a pair of bevel gears 63. By this interlocking, the endless chain 58A rotates clockwise in a front view. By this rotation, each pulling claw 59A moves from the left end side to the left and right center side of the cutting and conveying unit 3 in the area Aa1 where the first guide rail 61A is held in the downward acting posture. A maximum of two crop C grains introduced between the left weed member 21 </ b> A and the middle weed member 21 </ b> C are scraped and guided toward the left and right center side of the cutting and conveying unit 3. Moreover, in area | region Aa2 hold | maintained by the 2nd guide rail 62A at a horizontal action attitude | position, it moves toward the upper part from the lower end part of the raising case 52A, and this movement causes the culm of the crop C after the rake guidance. .
 右側の引起装置22Bは、その入力軸53Bがチェーン式伝動機構64と一対のベベルギヤ65とを介して右伝動軸48と連動する。この連動により、その無端チェーン58Bが正面視において左回りに回動する。この回動により、各引起爪59Bが、第1ガイドレール61Bにより下向きの作用姿勢に保持される領域Ab1では、刈取搬送部3の右端側から左右中央側に向けて移動し、この移動により、右分草部材21Bと中分草部材21Cとの間に導入された最大2条の作物Cの穀稈を刈取搬送部3の左右中央側に向けて掻き込み案内する。また、第2ガイドレール62Bにより横向きの作用姿勢に保持される領域Ab2では、引起ケース52Bの下端部から上部に向けて移動し、この移動により、掻き込み案内後の作物Cの穀稈を引き起こす。 The input shaft 53B of the right pulling device 22B is interlocked with the right transmission shaft 48 via the chain transmission mechanism 64 and the pair of bevel gears 65. By this interlocking, the endless chain 58B rotates counterclockwise when viewed from the front. By this rotation, each pulling claw 59B moves from the right end side of the cutting and conveying unit 3 toward the left and right center side in the region Ab1 where the first guide rail 61B is held in the downward acting posture. A maximum of two crop C culms introduced between the right weed member 21B and the middle weed member 21C are scooped and guided toward the left and right center side of the cutting and conveying unit 3. Moreover, in area | region Ab2 hold | maintained by the 2nd guide rail 62B at the horizontal action attitude | position, it moves toward the upper part from the lower end part of the raising case 52B, and this movement causes the grain culm of the crop C after rake guidance. .
 つまり、左右の引起装置22A,22Bには、それらに備えた複数の引起爪59A,59Bにより、3つの分草部材21A~21Cのうちの対応するものの間に導入された作物Cの穀稈を刈取搬送部3の左右中央側に向けて掻き込み案内する案内領域Aa1,Ab1と、掻き込み案内した作物Cの穀稈を引き起こす引き起こし領域Aa2,Ab2とを形成してある。 In other words, the left and right pulling devices 22A and 22B receive the grain culm of the crop C introduced between the corresponding ones of the three weeding members 21A to 21C by the plurality of pulling claws 59A and 59B provided for them. Guide areas Aa1 and Ab1 for scrambling and guiding toward the left and right central side of the cutting and conveying unit 3 and cause areas Aa2 and Ab2 for causing culling of the crop C which has been scorched and guided are formed.
 そして、左側の引起装置22Aは、刈取搬送部3の入力軸38から、伝動軸40、中継軸42、動力分配軸44、および左伝動軸46、などを介して伝達される動力により作動し、この作動により、左分草部材21Aと中分草部材21Cとの間に導入された最大2条の作物Cの穀稈を引き起こすように構成してある。 The left pulling device 22A is operated by the power transmitted from the input shaft 38 of the cutting and conveying unit 3 via the transmission shaft 40, the relay shaft 42, the power distribution shaft 44, the left transmission shaft 46, and the like. By this operation, a maximum of two crop C grains are introduced between the left weed member 21A and the middle weed member 21C.
 また、右側の引起装置22Bは、刈取搬送部3の入力軸38から、伝動軸40、中継軸42、動力分配軸44、右伝動軸48、およびチェーン式伝動機構62、などを介して伝達される動力により作動し、この作動により、右分草部材21Bと中分草部材21Cとの間に導入された最大2条の作物Cの穀稈を引き起こすように構成してある。 The right pulling device 22B is transmitted from the input shaft 38 of the cutting and conveying unit 3 through the transmission shaft 40, the relay shaft 42, the power distribution shaft 44, the right transmission shaft 48, the chain transmission mechanism 62, and the like. It is configured to cause a maximum of two crop C culms introduced between the right weed member 21B and the middle weed member 21C.
 これにより、左右の引起枠26A,26Bを最大2条の穀稈を引き起こす2条用に構成することができ、刈取搬送部3を、左右一対の引起枠26A,26Bにより最大4条の作物Cの収穫を行う2枠4条刈り仕様に構成することができる。その結果、4つの分草部材と3つの引起装置とを備えて最大4条の作物Cの収穫を行なうように構成した一般的な3枠4条刈り仕様の刈取搬送部に比較して、同様の広い作業幅を有するように構成しながら、構成の簡素化やコストの削減を図ることができる。 Accordingly, the left and right pulling frames 26A and 26B can be configured for two lines that cause a maximum of two grain culms, and the cutting and conveying unit 3 is formed by a pair of left and right pulling frames 26A and 26B. It can be configured to a 2-frame 4-strip cutting specification for harvesting. As a result, as compared with a general three-frame four-line mowing specification cutting and conveying unit configured to harvest four crops C at maximum with four weed members and three pulling devices. The configuration can be simplified and the cost can be reduced while being configured to have a wide working width.
 また、左右の引起装置22A,22Bに案内領域Aa1,Ab1と引き起こし領域Aa2,Ab2とを形成することにより、構成の簡素化が図られた2枠4条仕様でありながら、4条の作物穀稈を円滑かつ良好に引き起こすことができる。 Further, by forming guide areas Aa1 and Ab1 and raising areas Aa2 and Ab2 in the left and right pulling devices 22A and 22B, the structure of the two-frame four-line specification is simplified, but four crop grains Can cause wrinkles smoothly and well.
 しかも、刈取搬送部3を、左右の引起装置22A,22Bの上部にわたって、それらの上部に配備した入力軸53A,53Bを連動連結するための重量の大きい軸式伝動機構を架設する必要のないアーチレス構造に構成することができ、これにより、左右の引起装置
22A,22Bの上部にわたって軸式伝動機構を架設するアーチ構造を採用する場合に比較して、刈取搬送部3の重心位置を低くすることができ、車体の安定性を向上させることができる。
In addition, the archless that does not need to install a heavy shaft transmission mechanism for interlockingly connecting the input and receiving shafts 53A and 53B provided on the upper parts of the left and right pulling devices 22A and 22B. As a result, the centroid position of the cutting and conveying section 3 can be lowered as compared with the case where an arch structure in which an axial transmission mechanism is installed over the upper portions of the left and right pulling devices 22A and 22B is adopted. And the stability of the vehicle body can be improved.
 ところで、図示は省略するが、3枠4条刈り仕様の刈取搬送部にアーチレス構造を採用する場合には、刈取搬送部の左右中央側に配置する引起装置に対する伝動系を、穀稈の搬送通路の下方となる刈取搬送部の左右中央側の底部に配備する必要がある。このような位置に伝動系を配置すると、伝動系のケース上に泥や雑草などの異物が堆積しやすくなり、この堆積した異物に穀稈が接触すると、穀稈の搬送姿勢に乱れが生じるようになり、この乱れに起因して、供給搬送装置25により穀稈を脱穀装置4に向けて搬送する際の穂先側の揃いが悪くなる。すると、脱穀装置4での脱穀処理の際に扱き残しが発生しやすくなり、穀粒回収効率の低下を招きやすくなる。 By the way, although not shown in the figure, when an archless structure is adopted for the cutting and conveying part of the three-frame four-saw cutting specification, the transmission system for the pulling device disposed on the left and right center side of the cutting and conveying part is used as the conveying path for the cereals. It is necessary to arrange at the bottom of the left and right center side of the cutting and conveying unit that is below. If the transmission system is arranged in such a position, foreign matters such as mud and weeds are likely to accumulate on the transmission system case, and if the culm comes into contact with the accumulated foreign matter, the conveying posture of the cereal may be disturbed. Due to this disturbance, the alignment on the tip side becomes worse when the supply and transport device 25 transports the cereal toward the threshing device 4. Then, in the case of the threshing process in the threshing device 4, unhandled residue is likely to occur, and the grain recovery efficiency is likely to be reduced.
 これに対し、本発明に係る刈取搬送部3は、4条刈りでありながら左右中央側の引起装置を必要としない2枠4条刈り仕様であることから、そのような異物の堆積に起因した穀粒回収効率の低下を未然に回避することができる。 On the other hand, the cutting and conveying unit 3 according to the present invention is a two-frame four-row cutting specification that does not require a pulling device on the left and right center sides while being a four-row cutting, and thus is caused by the accumulation of such foreign matters. A drop in grain recovery efficiency can be avoided in advance.

That is, the upper part of the right pulling case 52B is supported by the support member 36 via the connecting member 67 and the left pulling case 52A. With these support structures, the left and right pulling devices 22A and 22B are mounted on the cutting and conveying unit 3 in a rearward tilt position located on the rear side of the vehicle body as the upper side thereof.
 なお、左右の引起装置22A,22Bとして、複数の引起爪59A,59Bを左右方向に掻き込み移動させることにより案内領域Aa1,Ab1を形成する構造のものに代えて、車体の走行に伴って、作物Cの穀稈を引き起こし領域Aa2,Ab2に向けて左右方向に摺動案内するガイド部材により案内領域Aa1,Ab1を形成する構造のもの採用するようにしてもよい。 As the left and right pulling devices 22A and 22B, instead of the structure in which the guide areas Aa1 and Ab1 are formed by scraping and moving the plurality of pulling claws 59A and 59B in the left and right directions, as the vehicle body travels, You may make it employ | adopt the structure which forms guide area | region Aa1 and Ab1 with the guide member which raises the grain culm of crop C, and slides and guides toward area | region Aa2 and Ab2.

A plurality of movable blades 68 aligned and arranged in a straight line in the left-right direction on the upper side thereof, and a plurality of fixed blades arranged in a line in a straight line in the left-right direction on the lower side thereof By reciprocating with a fixed stroke in the left-right direction with respect to 69, the cereal of the crop C caused by the left and right pulling devices 22A, 22B is cut off. Each movable blade 68 slides back and forth with a fixed stroke in the left-right direction with respect to the fixed blade 69 by interlocking with the power distribution shaft 44 via a crank-type cutting blade driving device 70.
 つまり、刈取装置23は、刈取搬送部3の動力分配軸44から刈刃駆動装置70を介して伝達される動力により作動し、この作動により、左右の引起装置22A,22Bにより引き起こした作物Cの穀稈を刈り取るように構成してある。 In other words, the cutting device 23 is operated by the power transmitted from the power distribution shaft 44 of the cutting conveyance unit 3 via the cutting blade driving device 70, and by this operation, the crop C caused by the left and right pulling devices 22A and 22B is operated.

And by this up-and-down swing, the conveyance start end part 25b can be position-adjusted in the cocoon length direction with respect to the culm that has passed through the culm passing part 27. The supply length on the tip side with respect to the inside of the threshing device 4 can be changed, and the handling depth adjustment for adjusting the handling depth of the cereal by the threshing device 4 can be performed.
 刈取搬送部3には、供給搬送装置25の左右方向への振れを抑制しながら、供給搬送装置25の搬送始端部25bを上下方向に揺動案内するガイド杆86を立設してある。ガイド杆86は、供給搬送装置25の揺動支点を中心とする円弧状に湾曲形成してある。 The cutting and conveying unit 3 is provided with a guide rod 86 that swings and guides the conveyance start end portion 25b of the supply and conveyance device 25 in the vertical direction while suppressing the horizontal movement of the supply and conveyance device 25. The guide rod 86 is curved in a circular arc shape with the swing fulcrum of the supply / conveyance device 25 as the center.
 供給搬送装置25には、刈取搬送部3の入力軸38を支点にして供給搬送装置25を上下方向に揺動駆動することにより、供給搬送装置25の搬送始端部25bを、穀稈通過部27を通過した穀稈に対して稈長方向に位置調節する調節手段87を装備してある。また、供給搬送装置25の穀稈搬送経路88を跨いで株元挟持搬送機構82の挟持ガイド杆89を支持する支持フレーム90を備えてある。 The supply / conveyance device 25 is configured to swing the supply / conveyance device 25 in the up / down direction with the input shaft 38 of the cutting / conveyance unit 3 as a fulcrum. The adjusting means 87 which adjusts the position in the cocoon length direction with respect to the cereal cake that has passed through is provided. In addition, a support frame 90 is provided that supports the pinching guide rods 89 of the stock holding pinch conveyance mechanism 82 across the grain haul conveyance route 88 of the supply conveyance device 25.
 調節手段87は、刈取搬送部3に備えた電動モータ91の作動により、電動モータ91の出力軸(図示せず)に備えたピニオンギヤ(図示せず)と、このピニオンギヤと噛合するセクタギヤ92とを介して、セクタギヤ92に一体装備した揺動アーム93を揺動することにより、揺動アーム93に吊下ロッド94を介して連係した供給搬送装置25を上下方向に揺動駆動するように構成してある。 The adjusting means 87 operates a pinion gear (not shown) provided on an output shaft (not shown) of the electric motor 91 and a sector gear 92 meshing with the pinion gear by the operation of the electric motor 91 provided in the cutting and conveying unit 3. Thus, by swinging the swing arm 93 integrally provided in the sector gear 92, the supply and transport device 25 linked to the swing arm 93 via the suspension rod 94 is driven to swing in the vertical direction. It is.
 支持フレーム90には、供給搬送装置25により搬送される穀稈の穂先位置を検出する穂先センサ95を備えてある。穂先センサ95には、一対のセンサアーム96A,96Bを備えている。一対のセンサアーム96A,96Bは、供給搬送装置25により搬送される穀稈の穂先側において、稈長方向に所定間隔をあけて位置するように配置してある。そして、穂先センサ95は、一対のセンサアーム96A,96Bにより検出した穀稈の穂先位置を、マイクロコンピュータを利用して構成した制御装置97に出力する。制御装置97には、穂先センサ95の出力に基づいて、脱穀装置4の内部に供給する穀稈の穂先側の長さが一定になるように調節手段87の電動モータ91の作動を制御する扱き深さ調節用の制御手段97Aを備えてある。制御手段97Aは、穀稈の株元側に位置するセンサアーム96Aが穀稈の穂先側を検出し、かつ、穀稈の穂先側に位置するセンサアーム96Bが穀稈の穂先側を検出しない状態が維持されるように、電動モータ91の作動を制御することにより、脱穀装置4の内部に供給する穀稈の穂先側の長さを一定にする。 The support frame 90 is provided with a tip sensor 95 that detects the tip position of the cereal that is transported by the supply and transport device 25. The tip sensor 95 includes a pair of sensor arms 96A and 96B. The pair of sensor arms 96 </ b> A and 96 </ b> B are arranged so as to be positioned at a predetermined interval in the cocoon length direction on the tip side of the grain pods conveyed by the supply conveyance device 25. Then, the tip sensor 95 outputs the tip position of the grain pod detected by the pair of sensor arms 96A and 96B to a control device 97 configured using a microcomputer. The control device 97 handles the operation of the electric motor 91 of the adjusting means 87 so that the length of the tip side of the cereal supplied to the inside of the threshing device 4 is constant based on the output of the tip sensor 95. A control means 97A for adjusting the depth is provided. The control means 97A is in a state in which the sensor arm 96A located on the stock side of the grain pod detects the tip side of the grain pod and the sensor arm 96B located on the side of the grain pod does not detect the tip side of the grain pod By controlling the operation of the electric motor 91, the length of the tip side of the corn straw supplied to the inside of the threshing device 4 is made constant.
 図示は省略するが、一対のセンサアーム96A,96Bは、供給搬送装置25が搬送する穀稈に対する稈長方向での位置変更を一体的に行えるように構成してある。そして、この位置変更により、両センサアーム96A,96Bの位置を穀稈の株元側に変更することにより、脱穀装置4による穀稈の扱き深さを、脱穀装置4の内部に供給する穀稈の穂先長さを短くする浅扱き側に調節することができる。また、両センサアーム96A,96Bの位置を穀稈の穂先側に変更することにより、脱穀装置4による穀稈の扱き深さを、脱穀装置4の内部に供給する穀稈の穂先長さを長くする深扱き側に調節することができる。 Although illustration is omitted, the pair of sensor arms 96A and 96B are configured so as to be able to integrally change the position in the cocoon length direction with respect to the cereals conveyed by the supply conveyance device 25. And by this position change, the position of both sensor arms 96A and 96B is changed to the stockholder side of the cereal, thereby the cereal that supplies the threshing depth of the cereal by the threshing device 4 to the inside of the threshing device 4 It can be adjusted to the shallow handling side to shorten the tip length. Further, by changing the position of both sensor arms 96A and 96B to the tip side of the cereal, the handling depth of the cereal by the threshing device 4 is increased, and the tip length of the cereal that supplies the inside of the threshing device 4 is increased. It can be adjusted to the deep handling side.
 図1~3、図6および図7に示すように、穂先センサ95には、一対のセンサアーム96A,96Bの位置変更操作を可能にする操作レバー98を装備してある。操作レバー98は、穂先センサ95における搭乗運転部2に近い位置に位置するように配置設定してある。これにより、搭乗運転部2に居ながら操作レバー98を操作することができ、脱穀装置4による穀稈の扱き深さを調節することができる。 As shown in FIGS. 1 to 3, 6 and 7, the tip sensor 95 is provided with an operation lever 98 that enables the position changing operation of the pair of sensor arms 96 </ b> A and 96 </ b> B. The operation lever 98 is set so as to be located at a position close to the boarding operation unit 2 in the tip sensor 95. Thereby, the operation lever 98 can be operated while staying in the boarding operation part 2, and the handling depth of the cereal by the threshing apparatus 4 can be adjusted.
 図8、図9および図13に示すように、刈取搬送部3において、中分草部材21Cは、穀稈通過部27の左右幅内である左右のパッカ72A,72Bの谷径da,dbの間に位置するように配置してある。 As shown in FIGS. 8, 9, and 13, in the cutting and conveying unit 3, the middle weed member 21 </ b> C has the valley diameters da and db of the left and right packers 72 </ b> A and 72 </ b> B that are within the left and right widths of the grain passer 27. It is arranged so as to be located between them.
 この配置により、左右の掻込搬送装置24A,24Bによって刈り取り後の穀稈を穀稈通過部27に向けて搬送する際に、その穀稈が中分草部材21Cを跨ぐようにして移動することを防止することができる。その結果、穀稈が中分草部材21Cを跨ぐ場合に比較して、その穀稈の株元側を中分草部材21Cに接触しにくくすることができ、これにより、その接触により穀稈の搬送姿勢が乱れることに起因して、供給搬送装置25により穀稈を脱穀装置4に向けて搬送する際の穂先側の揃いが悪くなり、脱穀装置4での脱穀処理において扱き残しが発生しやすくなる、といった穀粒回収率の低下を未然に回避することができる。 With this arrangement, when the cedar after harvesting is transported toward the cereal passing part 27 by the left and right scraping and conveying devices 24A and 24B, the cereal is moved so as to straddle the middle weed member 21C. Can be prevented. As a result, compared with the case where the cereals straddle the middle weed member 21C, the stock side of the cereal can be made less likely to come into contact with the middle weed member 21C. Due to the disorder of the conveying posture, the alignment of the tip side when conveying the cereal toward the threshing device 4 by the supply conveying device 25 becomes worse, and unhandled residue is likely to occur in the threshing process in the threshing device 4. It is possible to avoid a decrease in the grain recovery rate.
 また、前述したように、左右の掻込搬送装置24A,24Bは、刈取搬送部3を作業領域内に位置させた状態では、それらの掻込搬送機構71A,71Bの姿勢が、刈取搬送部3の左右中央側ほど後方に位置する傾斜姿勢で、かつ、後上がりの傾斜姿勢となり、また、それらのパッカ72A,72Bの姿勢が、後上がりの傾斜姿勢となることにより、刈取搬送部3を作業領域内に位置させた場合に水平姿勢または略水平姿勢になる中分草部材21Cに対しては、その搬送方向下手側ほど中分草部材21Cから上方に離れるようになる。これにより、左右の掻込搬送装置24A,24Bによって穀稈通過部27に向けて掻き込み搬送される穀稈が、穀稈通過部27において中分草部材21Cに接触することを防止することができ、結果、その接触による穀稈の搬送姿勢の乱れに起因した穀粒回収率の低下を阻止することができる。 In addition, as described above, the left and right scavenging and conveying devices 24A and 24B are configured so that the posture of the scavenging and conveying mechanisms 71A and 71B is the cutting and conveying unit 3 in a state where the cutting and conveying unit 3 is positioned in the work area. The left and right central sides of the packer 72A and the rearwardly inclined posture are rearwardly inclined and the postures of the packers 72A and 72B are rearwardly upward inclined postures. With respect to the middle weed member 21C that assumes a horizontal posture or a substantially horizontal posture when positioned in the area, the lower side in the transport direction is separated from the middle weed member 21C upward. Thereby, it is possible to prevent the cereal straw that has been scraped and conveyed toward the cereal passing part 27 by the left and right rake conveying devices 24A and 24B from contacting the middle weed member 21C in the cereal passing part 27. As a result, it is possible to prevent a decrease in the grain recovery rate due to the disturbance of the posture of conveying the culm due to the contact.
 図15は4条刈りの作業状態を示す要部の概略平面図、図16は3条刈りの作業状態を示す要部の概略平面図である。図3、図4、図15および図16に示すように、刈取搬送部3の左側端(刈取搬送部3における搭乗運転部2から離れる側の左右一側端)に位置する左分草部材21Aと、左側(搭乗運転部2から離れる側)のクローラ13Aは、左分草部材21Aの分草始端21Aaと左側のクローラ13Aの左端部13Aaとの車体左右方向での位置が一致するように配置してある。また、刈取搬送部3の右側端(刈取搬送部3における搭乗運転部側の左右一側端)に位置する右分草部材21Bと、右側(搭乗運転部側)のクローラ13Bは、右側のクローラ13Bの右端部13Baが、右分草部材21Bの分草始端21Baから車体右外方側に少しだけ食み出す状態で、右分草部材21Bの分草始端21Baと右側のクローラ13Bの右端部13Baとの車体左右方向での位置が略一致するように配置してある。 FIG. 15 is a schematic plan view of a main part showing a working state of four-line cutting, and FIG. 16 is a schematic plan view of a main part showing a working state of three-line cutting. As shown in FIGS. 3, 4, 15, and 16, the left weeding member 21 </ b> A located at the left end of the mowing and conveying unit 3 (one left and right end on the side away from the boarding operation unit 2 in the mowing and conveying unit 3). The crawler 13A on the left side (the side away from the boarding operation unit 2) is arranged so that the positions of the left weeding start end 21Aa of the left weeding member 21A and the left end portion 13Aa of the left crawler 13A in the left-right direction of the vehicle body coincide with each other. It is. Also, the right weeding member 21B located at the right end of the cutting and conveying section 3 (one left and right end on the boarding operation section side in the cutting and conveying section 3) and the right crawler 13B on the right (boarding operation section side) are crawlers on the right side. The right end portion 13Ba of the right weeding member 21B slightly protrudes from the weeding start end 21Ba of the right weeding member 21B to the right outer side of the vehicle body, and the right end portion of the right weeding member 21B and the right crawler 13B. It is arranged so that the position of 13Ba in the left-right direction of the vehicle body substantially matches.
 つまり、左右のクローラ13A,13Bは、それらの車体横外方側の端部間距離Lが、最大4条の刈り取り搬送が可能となるように構成した刈取搬送部3の作業幅Wよりも大きくなるように、左右方向に所定間隔をあけて配置してある。これにより、左右のクローラ13A,13Bの轍間距離を長くすることができ、各クローラ13A,13Bの接地長さを長くすることによる旋回性能の低下を招くことなく、湿田性能を向上させることができる。 In other words, the left and right crawlers 13A, 13B have a distance L between the end portions on the laterally outer side of the vehicle body larger than the working width W of the cutting and conveying unit 3 configured to enable the cutting and conveying of up to four items. Thus, they are arranged at predetermined intervals in the left-right direction. As a result, the distance between the left and right crawlers 13A and 13B can be increased, and the wetland performance can be improved without causing a decrease in turning performance by increasing the contact length of each of the crawlers 13A and 13B. it can.
 また、左側のクローラ13Aは、その左端部13Aaの位置が左分草部材21Aの分草始端21Aaと左右方向で一致することにより、その分草始端21Aaから車体左側に食み出さないようになっている。これにより、走行車体1の左外側方に未刈りの作物Cxが存在する回り刈りや走行車体1の左右両外側方に未刈りの作物Cx,Cyが存在する中割りなどの作業走行時に、左側のクローラ13Aにより、その左外側近傍に位置する未刈りの作物Cxを踏み付ける、あるいは、左側のクローラ13Aにより、その左外側近傍に位置する未刈りの作物Cxに泥寄せする、などの不都合の発生を防止することができ、その踏み付けや泥寄せに起因した作業効率の低下を回避することができる。 In addition, the left crawler 13A is prevented from protruding to the left side of the vehicle body from the grass start end 21Aa because the position of the left end portion 13Aa coincides with the weed start end 21Aa of the left weed member 21A in the left-right direction. ing. As a result, the left side of the traveling vehicle body 1 such as an uncut crop Cx that exists on the left outer side of the traveling vehicle body 1 or a middle split operation that includes uncut crops Cx and Cy on the left and right outer sides of the traveling vehicle body 1 The crawler 13A steps on an uncut crop Cx located near the left outer side, or the left crawler 13A muds the uncut crop Cx located near the left outer side. Generation | occurrence | production can be prevented and the fall of the working efficiency resulting from the stepping and mud gathering can be avoided.
 一方、右側のクローラ13Bは、その右端部13Baの位置が右分草部材21Bの分草始端21Baと左右方向で略一致することにより、走行車体1の左右両外側方に未刈りの作物Cx,Cyが存在する中割りなどの作業走行時に、右分草部材21Bの分草始端21Baが、刈取搬送部3の作業幅内最右の作物Cbと、この作物Cbと隣り合う作業幅外の作物Cyとの間における、作業幅内の作物Cbの側近を通るように設定すれば、右側のクローラ13Bにより、その右外側近傍に位置する未刈りの作物Cyを踏み付ける、といった不都合の発生を防止することができ、その踏み付けに起因した作業効率の低下を回避することができる。 On the other hand, the crawler 13B on the right side has its right end portion 13Ba substantially coincides with the weed start end 21Ba of the right weed member 21B in the left-right direction. At the time of work traveling such as splitting where Cy is present, the weeding start edge 21Ba of the right weeding member 21B is the rightmost crop Cb within the work width of the cutting and conveying unit 3 and the crop outside the work width adjacent to this crop Cb. If it is set so that it passes through the side of the crop Cb within the work width with the Cy, the right crawler 13B prevents the inconvenience of stepping on the uncut crop Cy located near the right outside. And a decrease in work efficiency due to the trampling can be avoided.
 ちなみに、右側のクローラ13Bにおける右分草部材21Bの分草始端21Baから車体右外方側への食み出し長さLzは、右側のクローラ13Bによる車体右外側近傍の未刈り作物Cyの踏み付けを防止できる長さであれば、例えば、作物Cの植え付け間隔Scとの関係から、Lz=1/3*ScやLz=1/4*Scなどの種々の長さに設定することが可能であるが、Lz≦1/6*Scとすることが好ましい。そして、その食み出し長さLzが短いほど、右側のクローラ13Bによる車体右外側近傍の未刈り作物Cyに対する泥寄せを抑制することができ、その泥寄せに起因した作業効率の低下を抑制することができる。逆に、その食み出し長さLzが長いほど、左右のクローラ13A,13Bの轍間距離を長くすることができ、湿田性能を向上させることができる。 Incidentally, the protrusion length Lz of the right weeding member 21B on the right crawler 13B from the starting weeding end 21Ba to the right outer side of the vehicle body is determined by the right crawler 13B being stepped on the uncut crop Cy near the right outer side of the vehicle body. If the length can be prevented, for example, it can be set to various lengths such as Lz = 1/3 * Sc and Lz = 1/4 * Sc from the relationship with the planting interval Sc of the crop C. However, it is preferable to satisfy Lz ≦ 1/6 * Sc. And as the protrusion length Lz is shorter, mud gathering on the uncut crop Cy near the right outer side of the vehicle body by the crawler 13B on the right side can be suppressed, and the reduction in work efficiency due to the mud gathering can be suppressed. be able to. Conversely, the longer the protrusion length Lz, the longer the distance between the left and right crawlers 13A and 13B can be, and the wetland performance can be improved.
 つまり、回り刈りや中割りなどの作業走行時に、左右のクローラ13A,13Bによる未刈り作物Cx,Cyの踏み付けや未刈り作物Cx,Cyへの泥寄せを防止することのできる全面狩り仕様に構成することができる。 That is, it is configured as a full hunting specification that can prevent the left and right crawlers 13A, 13B from stepping on the uncut crops Cx, Cy and mud approaching to the uncut crops Cx, Cy during work such as turning and middle cutting. can do.
 なお、右側のクローラ13Bを、その右端部13Baが右分草部材21Bの分草始端21Baと左右方向で一致する、または、右分草部材21Bの分草始端21Baよりも車体内方側に位置するように配置してもよい。また、左側のクローラ13Aを、その左端部13Aaが左分草部材21Aの分草始端21Aaよりも車体内方側に位置するように配置してもよく、また、左側のクローラ13Aによる車体左外側近傍の未刈り作物Cxの踏み付けを防止でき、かつ、未刈り作物Cxに対する泥寄せを抑制できる範囲内で、その左端部13Aaが左分草部材21Aの分草始端21Aaよりも車体左外方側に位置するように配置してもよい。 The right crawler 13B is positioned such that its right end portion 13Ba coincides with the weeding start end 21Ba of the right weeding member 21B in the left-right direction, or is located inward of the weeding start end 21Ba of the right weeding member 21B. You may arrange so that. Further, the left crawler 13A may be arranged so that the left end portion 13Aa thereof is located on the inner side of the vehicle body with respect to the weed start end 21Aa of the left weed member 21A. The left end portion 13Aa of the left weeding member 21A is located on the left outer side of the vehicle body within a range in which it is possible to prevent the neighboring uncut crop Cx from being stepped on and to suppress mud gathering on the uncut crop Cx. You may arrange | position so that it may be located in.
 図15に示すように、3つの分草部材21A~21Cは、4条の作物Cを収穫する作業走行時に、右分草部材21Bを、その分草始端21Baが、刈取搬送部3の作業幅内最右の作物Cbと、この作物Cbと隣り合う右側の作業幅外の作物Cyまたは作物の刈り跡Czとの間における、作業幅内の作物Cbの側近を通るように、作物Cに対して位置合わせした場合には、中分草部材21Cが、その作用対象となる作業幅内の左右中央側に位置する2つの作物Cc,Cdの中間位置または略中間位置を通り、かつ、左分草部材21Aが、刈取搬送部3の作業幅内最左の作物Caと、この作物Caと隣り合う左側の作業幅外の作物Cxまたは作物の刈り跡Czとの間における、それらの中間位置よりも作業幅内の作物Caに近い位置を通るように配置してある。 As shown in FIG. 15, the three weeding members 21A to 21C have the right weeding member 21B at the time of the operation of harvesting the four crops C, and the starting width 21Ba of the corresponding weeding member 21B is the working width of the cutting and conveying unit 3. For the crop C to pass through the side of the crop Cb within the work width between the rightmost crop Cb and the crop Cy or crop cut Cz outside the right work width adjacent to the crop Cb. The middle weed member 21C passes through an intermediate position or a substantially intermediate position between the two crops Cc and Cd located on the left and right center sides within the work width to be acted on, and the left portion The grass member 21A is located between the leftmost crop Ca within the work width of the cutting and conveying unit 3 and the intermediate position between the crop Cx or the crop cut Cz outside the left work width adjacent to the crop Ca. Through the position close to the crop Ca within the working width It is arranged.
 つまり、4条刈りの作業走行時には、搭乗運転部2の前下方に位置することにより搭乗運転部2からの視認性の高い右分草部材21Bの分草始端21Baを、作業幅内の最右に位置する作物Cbの右横側近を通るように位置合わせすることにより、搭乗運転部2から離れることにより搭乗運転部2からの視認性の低い左分草部材21Aおよび中分草部材21Cを、それらの視認を行なうことなく、作物Cの植え付け位置から外れた適切な位置に通すことができ、それらの分草部材21A,21Cによる作物Cの押し倒しや踏み付けを回避することができる。 That is, at the time of the four-row cutting operation, the weeding start end 21Ba of the right weeding member 21B with high visibility from the boarding operation unit 2 is positioned at the front lower side of the boarding operation unit 2, and the rightmost within the working width The left weed member 21A and the middle weed member 21C having low visibility from the boarding operation unit 2 by moving away from the boarding operation unit 2 by positioning the crop Cb located near the right side of the crop Cb. Without visually recognizing them, it is possible to pass through an appropriate position that is out of the planting position of the crop C, and it is possible to avoid pushing down and stepping on the crop C by the weeding members 21A and 21C.
 これにより、作物Cの倒伏が激しい場合であっても、各分草部材21A~21Bを作物Cに対する適切な位置に容易かつ確実に位置合わせすることができ、各分草部材21A~21Bおよび左右の引起装置22A,22Bによる穀稈の引き起こしを効率よく行うことができる。 As a result, even if the lodging of the crop C is severe, each of the weeding members 21A to 21B can be easily and reliably aligned at an appropriate position with respect to the crop C, and each of the weeding members 21A to 21B and the left and right The pulling devices 22A and 22B can be used to efficiently raise cereals.
 また、中分草部材21Cが、作業幅内の左右中央側に位置する2つの作物Cc,Cdの中間位置または略中間位置を通ることにより、左側の引起枠26Aの枠内に導入される2条の作物Ca,Ccの穀稈と、右側の引起枠26Bの枠内に導入される2条の作物Cb,Cdの穀稈とを、中分草部材21Cの真上に位置する穀稈通過部27を挟んだ左右対称の位置に位置させることができ、その左右対象となる穀稈の穀稈通過部27からの距離を一様に短くすることができる。 Further, the middle weed member 21C is introduced into the frame of the left raising frame 26A by passing through an intermediate position or a substantially intermediate position between the two crops Cc and Cd located on the left and right center side within the work width 2. The cereals of the crops Ca and Cc and the cereals of the two crops Cb and Cd introduced in the frame of the right pulling frame 26B are passed through the cereals located just above the middle weed member 21C. It can be located in the left-right symmetrical position on both sides of the part 27, and the distance from the culm passing part 27 of the cereals which become the right and left object can be shortened uniformly.
 これにより、左右の引起枠26A,26Bに2条ずつの作物Cの穀稈を導入するようにしながらも、中分草部材21Cが、作業幅内の左右中央側に位置する2つの作物Cc,Cdの中間位置から大きく外れることにより、左右の引起枠26A,26Bのいずれか一方に導入される穀稈の穀稈通過部27からの距離が不必要に長くなり、左右いずれか一方の掻込搬送装置24A,24Bによる穀稈の搬送効率が低下することを防止することができる。また、左右いずれか一方の掻込搬送装置24A,24Bによる穀稈の搬送に不必要な遅れが生じることを防止することができ、この遅れに起因した穀稈の搬送姿勢の乱れにより、供給搬送装置25により穀稈を脱穀装置4に向けて搬送する際の穂先側の揃いが悪くなり、脱穀装置4での脱穀処理において扱き残しが発生しやすくなる、といった穀粒回収率の低下を防止することができる。 Thereby, while the grain culm of each crop C is introduced into the left and right pull-up frames 26A, 26B, the middle weed member 21C has two crops Cc, By greatly deviating from the intermediate position of Cd, the distance from the culm passing portion 27 of the cereal introduced into either one of the left and right pulling frames 26A, 26B becomes unnecessarily long, and either the left or right is scratched. It can prevent that the conveyance efficiency of the grain straw by conveyance apparatus 24A, 24B falls. Further, it is possible to prevent an unnecessary delay in the transportation of the cereals by either the left or right scraping and transporting device 24A, 24B. The apparatus 25 prevents a reduction in the grain recovery rate such that the alignment of the tip side when conveying the cereal toward the threshing device 4 is poor, and unhandled items are easily generated in the threshing process in the threshing device 4. be able to.
 しかも、左分草部材21Aが、作業幅内の最左に位置する作物Caの左横近くを通ることにより、4条の作物Cを収穫する作業走行時には、常に、右分草部材21Bの分草始端21Baを、作業幅内の最右に位置する作物Cbの右横側近を通るように位置合わせする必要が生じることになる。 In addition, when the left weed member 21A passes near the left side of the leftmost crop Ca within the work width, the right weed member 21B is always divided during the operation of harvesting the four crops C. It is necessary to align the grass start edge 21Ba so as to pass near the right side of the crop Cb located at the rightmost position within the work width.
 これにより、4条の作物Cを収穫する作業走行時には、常に、各分草部材21A~21
Cを、作物Cに対する上述した適切な位置に確実に通すことができるようになり、結果、4条の作物Cを収穫する作業走行時における作業性の向上を図ることができる。
As a result, the weeding members 21A to 21A are always operated during the operation of harvesting the four crops C.
C can be surely passed through the above-described appropriate position with respect to the crop C, and as a result, workability can be improved during the operation of harvesting the four crops C.
 図16に示すように、3つの分草部材21A~21Cは、3条の作物Cを収穫する作業走行時に、右分草部材21Bを、その分草始端21Baが、刈取搬送部3の作業幅内最右の作物Cbと隣り合う右側の作物の刈り跡Czの上方を通るように、右側の作物の刈り跡Czに対して位置合わせした場合には、中分草部材21Cが、その作用対象となる作業幅内の右側と左右中央側とに位置する2つの作物Cb,Ccの間における右側の作物Cbよりも左右中央側の作物Ccに近い位置を通り、かつ、左分草部材21Aが、その作用対象となる、刈取搬送部3の作業幅内最左の作物Caと、この作物Caと隣り合う左側の作業幅外の作物Cxまたは作物の刈り跡Czとの間の中間位置または略中間位置を通るように配置してある。 As shown in FIG. 16, the three weeding members 21A to 21C are arranged so that the right weeding member 21B is used for the operation of harvesting three crops C, and the starting weed 21Ba is the working width of the cutting and conveying unit 3. When positioning with respect to the right crop crop Cz so as to pass above the right crop crop Cz adjacent to the rightmost crop Cb, the middle weed member 21C is subject to its action. The left weeding member 21A passes through a position closer to the crop Cc on the right and left center side than the right crop Cb between the two crops Cb and Cc located on the right side and the left and right center side within the working width. The intermediate position between the leftmost crop Ca within the work width of the cutting and transporting unit 3 and the crop Cx outside the left work width adjacent to the crop Ca or the crop cutting trace Cz, which is the target of the action It is arranged to pass through an intermediate position.
 つまり、3条刈りの作業走行時には、搭乗運転部2の前下方に位置することにより搭乗運転部2からの視認性の高い右分草部材21Bの分草始端21Baを、右側の刈り跡Czの上方を通るように位置合わせすることにより、搭乗運転部2から離れることにより搭乗運転部2からの視認性の低い左分草部材21Aおよび中分草部材21Cを、それらの視認を行なうことなく、作物Cの植え付け位置から外れた適切な位置に通すことができ、それらの分草部材21A,21Cによる作物Cの押し倒しや踏み付けを回避することができる。 That is, at the time of the three-row cutting operation, the weeding start end 21Ba of the right weeding member 21B with high visibility from the boarding operation unit 2 is positioned at the front lower side of the boarding operation unit 2, and the right cutting mark Cz is By positioning so as to pass above, the left weeding member 21A and the middle weeding member 21C, which are less visible from the boarding driving unit 2 by moving away from the boarding driving unit 2, without visually recognizing them, It is possible to pass through an appropriate position away from the planting position of the crop C, and it is possible to avoid pushing down and stepping on the crop C by the weeding members 21A and 21C.
 これにより、作物Cの倒伏が激しい場合であっても、右分草部材21Bおよび中分草部材21Cを作物Cに対する適切な位置に容易かつ確実に位置合わせすることができ、各分草部材21A~21Bおよび左右の引起装置22A,22Bによる穀稈の引き起こしを効率よく行うことができる。 Thereby, even if the lodging of the crop C is intense, the right weed member 21B and the middle weed member 21C can be easily and reliably aligned at appropriate positions with respect to the crop C, and each weed member 21A. -21B and the left and right pulling devices 22A and 22B can efficiently cause cereals.
 また、中分草部材21Cが、作業幅内の左右中央側に位置する作物Ccの右横近くを通ることにより、左側の引起枠26Aの枠内に導入される2条の作物Ca,Ccの穀稈と、右側の引起枠26Bの枠内に導入される1条の作物Cbの穀稈のうち、中分草部材21Cの真上に位置する穀稈通過部27から最も離れる左側の作物Caの穀稈を、穀稈通過部27からの距離が最短になるようにすることができる。 Further, the middle weed member 21C passes near the right side of the crop Cc located on the left and right center side within the work width, so that the two crops Ca and Cc introduced into the frame of the left pulling frame 26A. Of the cereal grains and the cereal grains of one crop Cb introduced into the frame of the right pull-up frame 26B, the leftmost crop Ca from the cereal passage part 27 located directly above the middle weed member 21C Can be made to have the shortest distance from the grain passing section 27.
 これにより、左右の掻込搬送装置24A,24Bにより3条の穀稈を穀稈通過部27に向けて掻き込み搬送する際の搬送効率を向上させることができる。また、左右いずれか一方の掻込搬送装置24A,24Bによる穀稈の搬送に不必要な遅れが生じることを防止することができ、この遅れに起因した穀稈の搬送姿勢の乱れにより、供給搬送装置25により穀稈を脱穀装置4に向けて搬送する際の穂先側の揃いが悪くなり、脱穀装置4での脱穀処理において扱き残しが発生しやすくなる、といった穀粒回収率の低下を防止することができる。 Thereby, it is possible to improve the transport efficiency when the left and right scooping and transporting devices 24A and 24B scrape and transport the three rows of cereals toward the culm passing portion 27. Further, it is possible to prevent an unnecessary delay in the transportation of the cereals by either the left or right scraping and transporting device 24A, 24B. The apparatus 25 prevents a reduction in the grain recovery rate such that the alignment of the tip side when conveying the cereal toward the threshing device 4 is poor, and unhandled items are easily generated in the threshing process in the threshing device 4. be able to.
 しかも、左分草部材21Aが、作業幅内の最左に位置する作物Caと、左側の作業幅外の作物Cxまたは作物の刈り跡Czとの間の中間位置または略中間位置を通ることにより、3条の作物Cを収穫する作業走行時には、搭乗運転部2からの視認性が最も低い左分草部材21Aを、その作用対象の作物Cの植え付け位置から、その作用範囲内での最も離れた位置に位置させることができる。 Moreover, the left weeding member 21A passes through an intermediate position or a substantially intermediate position between the crop Ca located at the leftmost position within the work width and the crop Cx or the crop cutting trace Cz outside the left work width. When traveling for harvesting three crops C, the left weed member 21A having the lowest visibility from the boarding operation unit 2 is farthest from the planting position of the crop C to be acted on within the working range. Can be located at different positions.
 これにより、3条の作物Cを収穫する作業走行時には、搭乗運転部2からの視認性が最も低い左分草部材21Aを、その作用対象の作物Cに良好に作用させることができるとともに、左分草部材21Aが作用対象の作物Cの植え付け位置に位置することをより確実に防止することができる。 Thus, during the operation of harvesting the three crops C, the left weeding member 21A having the lowest visibility from the boarding operation unit 2 can be favorably applied to the crop C to be acted on, and the left It can prevent more reliably that the weeding member 21A is located in the planting position of the crop C to be acted on.
 ちなみに、上述した3つの分草部材21A~21Cと作物Cの位置関係を満たすための3つの分草部材21A~21Cの具体的な配置としては、3つの分草部材21A~21Cの左右間隔Sa,Sbと作物Cの植え付け間隔Scとの関係が、Sa=Sb=1.75*Scとなる配置や、Sa=Sb≒1.75*Scとなる配置、あるいは、Sa>SbでSa≒1.75*ScかつSb≒1.75*Scとなる配置や、Sa<SbでSa≒1.75*ScかつSb≒1.75*Scとなる配置、などが考えられる。そして、4条の作物Cを収穫する作業走行時には、左分草部材21Aとその右横に位置する作業幅内最左の作物Caとの離間距離Laが、右分草部材21Aとその左横に位置する作業幅内最右の作物Cbとの離間距離Lbよりも大きくなることが好ましい。 Incidentally, as a specific arrangement of the three weed members 21A to 21C for satisfying the positional relationship between the three weed members 21A to 21C and the crop C, the left-right distance Sa between the three weed members 21A to 21C is described. , Sb and the planting interval Sc of the crop C are arranged such that Sa = Sb = 1.75 * Sc, arrangement where Sa = Sb≈1.75 * Sc, or Sa> Sb and Sa≈1 .75 * Sc and Sb≈1.75 * Sc, and Sa <Sb and Sa≈1.75 * Sc and Sb≈1.75 * Sc are considered. When the four crops C are harvested, the distance La between the left weed member 21A and the leftmost crop Ca within the work width located on the right side of the left weed member 21A is the right weed member 21A and its left side. It is preferable that the distance Lb be larger than the distance Lb from the rightmost crop Cb in the work width located at the position.
 図3、図4および図8に示すように、左右の分草部材21A,21Bは、それらの分草具51A,51Bの姿勢が、車体後部側ほど車体左右方向の車体内方側に位置する傾斜姿勢となるように構成してある。これにより、刈取搬送部3の作業幅内の左右両端部に位置する作物Ca,Cbを、作業幅内の左右中央に向けて寄せやすくすることができる。 As shown in FIGS. 3, 4, and 8, the left and right weeding members 21 </ b> A and 21 </ b> B are positioned so that the postures of the weeding tools 51 </ b> A and 51 </ b> B are closer to the vehicle interior side in the vehicle lateral direction toward the rear of the vehicle body. It is configured to have an inclined posture. Thereby, the crops Ca and Cb positioned at the left and right ends in the work width of the cutting and conveying unit 3 can be easily moved toward the left and right center in the work width.
 図1~4および図6~9に示すように、刈取搬送部3には、左分草杆99Aと右分草杆99Bと中分草杆99Cとを備えてある。 As shown in FIGS. 1 to 4 and FIGS. 6 to 9, the cutting and conveying unit 3 includes a left weed ridge 99A, a right weed ridge 99B, and a middle weed ridge 99C.
 図1、図3、図4および図6に示すように、左分草杆99Aは、刈取搬送部3の左側部に、走行車体1の左外方に張り出すように傾倒した作用姿勢と、走行車体側に退避するように起立した格納姿勢とに、揺動による姿勢変更が可能となるように装備してある。そして、左分草杆99Aを作用姿勢に切り換えることにより、走行車体1の左外側方に存在する未刈り作物Cxの車体内方側への倒伏を阻止することができる。 As shown in FIGS. 1, 3, 4, and 6, the left weed tackle 99 </ b> A is tilted so as to project outward from the left side of the traveling vehicle body 1 to the left side of the cutting and conveying unit 3. It is equipped so that the posture can be changed by swinging to the retracted posture standing so as to retreat to the traveling vehicle body side. Then, by switching the left weed fence 99A to the action posture, it is possible to prevent the uncut crop Cx existing on the left outer side of the traveling vehicle body 1 from falling to the vehicle body inner side.
 図17は左分草杆99Aの分草終端部側の取り付け構造を示す要部の斜視図である。図1、図3、図4、図6および図17に示すように、左分草杆99Aは、その分草始端部99aを左分草具51Aに第1連結部100を介して揺動可能に連結してある。また、その分草終端部側から延出した連結杆101の延出端部101aを刈取搬送部3の支持部材36に第2連結部102を介して揺動可能に連結してある。 FIG. 17 is a perspective view of the main part showing the attachment structure on the weed terminal end side of the left weed fence 99A. As shown in FIGS. 1, 3, 4, 6, and 17, the left weed ridge 99 </ b> A is capable of swinging its starting weed end 99 a to the left weed tool 51 </ b> A via the first connecting portion 100. It is connected to. Further, the extended end portion 101 a of the connecting rod 101 extending from the end portion of the weed is connected to the support member 36 of the cutting and conveying unit 3 through the second connecting portion 102 so as to be swingable.
 第1連結部100は、左分草具51Aに溶接したL字状のブラケット103、および、このブラケット103に左分草杆99Aの分草始端部99aを揺動可能に連結する連結ピン104により、連結ピン104が左分草具51Aの左側部に近接するように構成してある。 The first connecting portion 100 includes an L-shaped bracket 103 welded to the left weeding tool 51A, and a connecting pin 104 that connects the bracket 103 to the weeding start end portion 99a of the left weed ridge 99A so as to be swingable. The connecting pin 104 is configured to be close to the left side portion of the left weed tool 51A.
 第2連結部102は、支持部材36に溶接したブラケット105、このブラケット105に連結杆101の延出端部101aを揺動可能に連結する連結ピン106、および、左分草杆99Aの姿勢保持を可能にする保持機構107により構成してある。そして、左側の引起枠26Aにおける左側端部の直後方箇所に存在する空間を有効利用して、第1連結部100よりも刈取搬送部3の左右中央側で、かつ、左側のクローラ13Aの左端部13Aaよりも走行車体1の左右中央側に位置するように配置してある。 The second connecting portion 102 includes a bracket 105 welded to the support member 36, a connecting pin 106 that swingably connects the extended end 101a of the connecting rod 101 to the bracket 105, and the posture of the left weed rod 99A. It is constituted by a holding mechanism 107 that enables the above. Then, by effectively using the space present immediately after the left end of the left pulling frame 26A, the left end of the crawler 13A on the left and right central side of the cutting and conveying unit 3 relative to the first connecting unit 100 It arrange | positions so that it may be located in the left-right center side of the traveling vehicle body 1 rather than part 13Aa.
 保持機構107は、連結ピン106を中心とする円弧状の長孔105aをブラケット105に形成し、この長孔105aにボルト108を挿通した後、このボルト108の挿通始端側に圧縮バネ109を外嵌し、一対のナット110を螺合して、圧縮バネ109の作用により、連結杆101の延出端部101aとブラケット105とを圧接することにより、長孔105aに沿った左分草杆99Aの作用姿勢と格納姿勢とにわたる揺動操作を許容しながら、左分草杆99Aの姿勢保持を行うように構成してある。 The holding mechanism 107 forms an arc-shaped long hole 105 a centering on the connecting pin 106 in the bracket 105, and after inserting the bolt 108 into the long hole 105 a, the compression spring 109 is removed from the insertion start end side of the bolt 108. The pair of nuts 110 are screwed together and the extension end portion 101a of the connecting rod 101 and the bracket 105 are pressed against each other by the action of the compression spring 109, whereby the left weed rod 99A along the long hole 105a. The posture of the left weed fence 99A is held while allowing the swinging operation between the action posture and the retracted posture.
 上記の構成により、第2連結部102を、保持機構107を備える大型に構成しても、左分草杆99Aの姿勢を格納姿勢に切り換えた状態で刈取搬送部3の左端部を畦際に位置させて畦際の作物Cを収穫する作業走行時などにおいて、第2連結部102が畦などの他物に接触して変形する虞を未然に回避することができる。これは、畦をコンクリートブロックなどにより低く形成した圃場において、そのコンクリートブロックとの接触による第2連結部102の変形を阻止する上において特に有効である。 With the above configuration, even if the second connecting portion 102 is configured to be large with the holding mechanism 107, the left end portion of the cutting and conveying unit 3 can be used in the state where the posture of the left weed tackle 99A is switched to the retracted posture. In the case of a traveling operation in which the second cropped portion C is placed and harvests the crop C at the time of dredging, it is possible to avoid the possibility that the second connecting portion 102 contacts and deforms other things such as the straw. This is particularly effective in preventing the deformation of the second connecting portion 102 due to contact with the concrete block in a farm field in which the ridges are formed low with a concrete block or the like.
 また、第1連結部100の連結ピン104と第2連結部102の連結ピン106との中心を通る左分草杆99Aの揺動軸心Pが、その刈取搬送部3の後部側ほど刈取搬送部3の左右中心側に位置する傾斜姿勢になることにより、左分草杆99Aの揺動軸心Pを刈取搬送部3の前後方向に沿う姿勢に設定する場合に比較して、左分草杆99Aを、格納姿勢と作用姿勢とにわたって揺動操作する際の操作角を小さくすることができ、左分草杆99Aの操作性を向上させることができる。 Further, the swing axis P of the left weed ridge 99A passing through the centers of the connection pin 104 of the first connection unit 100 and the connection pin 106 of the second connection unit 102 is cut and conveyed toward the rear side of the cutting and conveying unit 3. Compared to the case where the swing axis P of the left weed culvert 99A is set to a posture along the front-rear direction of the cutting and conveying unit 3 by the inclined posture positioned on the left and right center side of the portion 3, the left weed It is possible to reduce the operating angle when swinging the rod 99A between the retracted posture and the acting posture, and it is possible to improve the operability of the left weed rod 99A.
 図18は左分草杆99Aを格納姿勢に切り換えた状態を示す要部の平面図である。図4および図18に示すように、左分草杆99Aは、その格納姿勢では、その分草終端部99bが刈取搬送部3の左側端よりも走行車体1の左右中央側に位置する状態で、その分草終端部99bと刈取搬送部3の左側端との車体左右方向での位置が略一致するように構成してある。 FIG. 18 is a plan view of the main part showing a state where the left branch 99A is switched to the retracted position. As shown in FIGS. 4 and 18, in the retracted posture, the left weed rod 99 </ b> A is in a state in which the weed terminal end portion 99 b is located closer to the left and right center side of the traveling vehicle body 1 than the left end of the cutting and conveying unit 3. The position in the left-right direction of the vehicle body between the weed terminal portion 99b and the left end of the cutting and conveying unit 3 is configured to be substantially the same.
 これにより、左分草杆99Aは、その格納姿勢では、その分草終端部99bが左側のクローラ13Aの左端部13Aaよりも走行車体1の左右中央側に位置する状態で、その分草終端部99bと左側のクローラ13Aの左端部13Aaとの車体左右方向での位置が略一致するようになる。 As a result, the left weed culm 99A is in its retracted position with its weeding terminal end 99b positioned closer to the left and right center of the traveling vehicle body 1 than the left end 13Aa of the left crawler 13A. The positions of 99b and the left end 13Aa of the left crawler 13A in the left-right direction of the vehicle body substantially coincide with each other.
 つまり、左分草杆99Aを格納姿勢に切り換えることにより、左分草杆99Aの分草終端部99bを、刈取搬送部3の左側端および左側のクローラ13Aの左端部13Aaよりも走行車体1の左右中央側に位置させることができ、これにより、左分草杆99Aの全体を、左側のクローラ13Aの左端部13Aaよりも車体左外方側に位置する挟持搬送機構31の左外側端よりも車体左右方向での車体内方側に位置させることができる。その結果、左分草杆99Aの分草終端部99bなどが、挟持搬送機構31の左外側端よりも車体左外方側に位置する場合に比較して、左分草杆99Aを格納姿勢に切り換えた状態でのコンバイン全体としての左右幅を小さくすることができ、納屋などに対する収納性を向上させることができる。 That is, by switching the left weed rod 99A to the retracted position, the weed terminal end portion 99b of the left weed rod 99A is located on the traveling vehicle body 1 more than the left end 13Aa of the left crawler 13A and the left crawler 13A. It can be positioned on the left and right center side, so that the entire left weed fence 99A is more than the left outer end of the nipping and conveying mechanism 31 located on the left outer side of the vehicle body with respect to the left end portion 13Aa of the left crawler 13A. It can be located on the vehicle body inner side in the vehicle body left-right direction. As a result, as compared with the case where the weed terminal portion 99b of the left weed basket 99A is located on the left outer side of the vehicle body from the left outer end of the pinch transport mechanism 31, the left weed basket 99A is in the retracted position. The left and right widths of the combine as a whole in the switched state can be reduced, and the storage property for a barn or the like can be improved.
 左分草杆99Aは、その格納姿勢では、その分草終端部99bが供給搬送装置25の穀稈搬送経路88よりも車体上方側に位置するように構成してある。これにより、左分草杆99Aを格納姿勢に切り換えた状態においても、穀稈を、供給搬送装置25によって、左分草杆99Aの分草終端部99bに接触させることなく脱穀装置4に向けて搬送することができる。 In the retracted posture, the left weed culm 99A is configured such that the weed ending portion 99b is located on the upper side of the vehicle body relative to the grain culm transport path 88 of the supply transport device 25. Thereby, even in the state in which the left weed cocoon 99A is switched to the retracted position, the cereal is directed toward the threshing device 4 without being brought into contact with the weed terminal end portion 99b of the left weed culm 99A by the feeding and conveying device 25. Can be transported.
 つまり、左分草杆99Aを格納姿勢に切り換えた状態で作業走行を行なっても、供給搬送装置25により搬送される穀稈が左分草杆99Aの分草終端部99bに接触する虞を未然に回避することができる。その結果、その接触に起因して穀稈の搬送姿勢に乱れが生じることにより、穀稈の穂先側の揃いが悪くなり、脱穀装置4での脱穀処理において扱き残しが発生しやすくなる、といった穀粒回収率の低下を未然に回避することができる。 In other words, even if the left side weed basket 99A is switched to the retracted position, there is a risk that the cereal grain conveyed by the supply and transport device 25 may come into contact with the weed terminal end portion 99b of the left weed ridge 99A. Can be avoided. As a result, the cereal conveyance posture is disturbed due to the contact, so that the alignment of the tip side of the cereal is deteriorated, and the unprocessed cereal in the threshing process in the threshing device 4 is likely to occur. A decrease in the grain recovery rate can be avoided in advance.
 しかも、左分草杆99Aを格納姿勢に切り換えた状態では、左分草杆99Aの全体が、脱穀装置4の挟持搬送機構31の左外側端よりも車体左右方向での車体内方側に位置することにより、畦際で作業走行を行なう場合には、車体をより畦に近づけた状態で作業走行させることができ、畦際の作物Cに対する左分草部材21Aの位置合わせが行ないやすくなる。その結果、畦際での作業性を向上させることができる。 In addition, in the state where the left weed basket 99A is switched to the retracted position, the entire left weed basket 99A is located on the inner side of the vehicle body in the left-right direction of the vehicle body with respect to the left outer end of the pinch transport mechanism 31 of the threshing device 4. By doing so, when performing work traveling at the shore, it is possible to perform the traveling while the vehicle body is closer to the heel, and it becomes easier to align the left weed member 21A with respect to the crop C at the shore. As a result, workability at the heel can be improved.
 また、稈長が65~75cm程度で倒伏の虞が少ない短稈の作物Cに対しては、その穂先に左分草杆99Aが作用しないように左分草杆99Aを格納姿勢に切り換えておくことにより、左分草杆99Aが作物Cの穀稈に分草作用することによって穀稈から穀粒が離脱する虞を未然に回避することができ、その結果、穀粒回収効率を向上させることができる。これは、脱粒しやすいインディカ米などを収穫する際に特に有効である。 In addition, for crop C, which is about 65-75 cm long and has a low risk of lodging, the left weed cocoon 99A should be switched to the retracted position so that the left weed 99A does not act on the tip. Thus, it is possible to avoid the possibility that the left weed cocoon 99A acts as a weed on the cereal of the crop C, so that the grain can be removed from the cereal, and as a result, the grain recovery efficiency can be improved. it can. This is particularly effective when harvesting indica rice and the like that are easily shed.
 図1~4および図6~8に示すように、中分草杆99Cは、刈取搬送部3の前端部において、左右の引起装置22A,22Bの略左右中間位置に位置するように、中分草具51Cから連結部材67にわたって立設してある。 As shown in FIGS. 1 to 4 and FIGS. 6 to 8, the middle weed culm 99C is positioned at the front end of the cutting and conveying unit 3 so as to be positioned at a substantially intermediate position between the left and right pulling devices 22A and 22B. It is erected over the connecting member 67 from the grass tool 51C.
 これにより、左右の各引起装置22A,22Bの案内領域Aa1,Ab1における各引起爪59A,59Bの掻き込み作用により、他方の引起装置22A,22Bに向けて倒伏することにより、各引起装置22A,22Bの引き起こし領域Aa1,Ab1の車体前方側において車体正面視で交差するようになる作物Cの穀稈を、中分草杆99Cの分草作用により、対応する引起装置22A,22Bの引き起こし領域Aa1,Ab1に向けて左右に分けることができる。 As a result, each pulling device 22A, 22B falls down toward the other pulling device 22A, 22B by the scraping action of the pulling claws 59A, 59B in the guide areas Aa1, Ab1 of the left and right pulling devices 22A, 22B. The culm of crop C that crosses in the front of the vehicle body in the vehicle body front side of the cause areas Aa1 and Ab1 of 22B is caused by the weeding action of the middle weed culm 99C and the cause area Aa1 of the corresponding pulling devices 22A and 22B. , Ab1 can be divided into left and right.
 その結果、収穫する作物Cの穀稈が、各引起装置22A,22Bの案内領域Aa1,Ab1における各引起爪59A,59Bの掻き込み作用により、各引起装置22A,22Bの引き起こし領域Aa1,Ab1の車体前方側において、車体正面視で交差して絡み合う虞を回避することができ、その絡み合いに起因した作物穀稈の引き起こし効率の低下や引き起こし不良の発生を防止することができる。 As a result, the cereal of the crop C to be harvested is caused by the scraping action of the pulling claws 59A and 59B in the guide areas Aa1 and Ab1 of the pulling devices 22A and 22B, in the raising regions Aa1 and Ab1 of the pulling devices 22A and 22B. At the front side of the vehicle body, it is possible to avoid the possibility of crossing and entangled in front view of the vehicle body, and it is possible to prevent crop culm caused by the entanglement and reduce the efficiency and cause the occurrence of defects.
 図1~4に示すように、左右の各引起装置22A,22Bは、各分草具51A~51Cと車体の前方に位置する作物Cとの位置関係などを搭乗運転部2から視認する際に、搭乗運転部2からの視界を遮らないようにするために、車体の前後方向におけるフロントパネル14の直前位置に位置するように配置してある。 As shown in FIGS. 1 to 4, when the left and right pulling devices 22A and 22B visually recognize the positional relationship between the weed tools 51A to 51C and the crop C located in front of the vehicle body from the boarding operation unit 2, In order not to obstruct the field of view from the boarding operation unit 2, the vehicle is disposed so as to be positioned immediately before the front panel 14 in the front-rear direction of the vehicle body.
 図3、図4、図8、図12および図13に示すように、右側の引起枠26Bに備えた2条用の引起装置22Bは、その引き起こし領域Ab2が搭乗運転部2から離れる左側に位置するように構成してある。 As shown in FIGS. 3, 4, 8, 12, and 13, the two-row pulling device 22 </ b> B provided on the right pulling frame 26 </ b> B is located on the left side where the raising region Ab <b> 2 is separated from the boarding operation unit 2. It is comprised so that it may do.
 これにより、右側の引起枠26Bに、引き起こし領域Ab2が搭乗運転部側となる右側に位置するように構成した2条用の引起装置を装備する場合に比較して、搭乗運転部2からの車体前方に対する視界を良好にすることができ、車体前方の作業地などに対する搭乗運転部2からの視認性を向上させることができる。 As a result, the vehicle body from the riding operation section 2 is compared with the case where the right pulling frame 26B is equipped with a two-row pulling device configured such that the raising area Ab2 is positioned on the right side which is the boarding operation section side. The visibility to the front can be improved, and the visibility from the boarding operation unit 2 to the work place in front of the vehicle body can be improved.
 左右の引起装置22A,22Bは、それらの引き起こし領域Aa2,Ab2の左右幅Wa,Wbを、最大2条の穀稈の引き起こしに対応する幅広に形成してある。また、左右の引起装置22A,22Bに備える引起爪59A,59Bは、幅広の引き起こし領域Aa2,Ab2に対応する長尺に形成してある。 The left and right pulling devices 22A and 22B are formed such that the left and right widths Wa and Wb of the raising areas Aa2 and Ab2 are wide enough to correspond to the raising of two cereals. Further, the raising claws 59A, 59B provided in the left and right raising devices 22A, 22B are formed in a long length corresponding to the wide raising areas Aa2, Ab2.
 これにより、左右の引起装置22A,22Bが常に2条ずつの穀稈を引き起こす4条刈りの作業走行時において、穀稈が左右の対応する引き起こし領域Aa2,Ab2を通過する際の抵抗が許容範囲を超えることを防止することができる。その結果、4条刈りの作業走行時においても、左右の引起装置22A,22Bによる穀稈の引き起こしを円滑かつ良好に行なうことができる。 Accordingly, when the left and right pulling devices 22A and 22B are in a four-row mowing operation that always causes two ridges of potatoes, the resistance when the culm passes through the corresponding right and left trigger areas Aa2 and Ab2 is within an allowable range. Can be prevented. As a result, it is possible to smoothly and satisfactorily raise the cereal by the left and right pulling devices 22A and 22B even during the four-saw cutting operation.
 また、各引起爪59A,59Bを、幅広の引き起こし領域Aa2,Ab2に対応する長尺に形成することにより、幅広の引き起こし領域Aa2,Ab2において引起爪59A,59Bが穀稈に作用しなくなるデッドゾーンが形成されることを防止することができる。その結果、左右の引起装置22A,22Bの各引き起こし領域Aa2,Ab2を、2条の穀稈の通過を許容する幅広に形成しながらも、左右の引起装置22A,22Bによる穀稈の引き起こしを確実に行なうことができる。 In addition, by forming the pulling claws 59A and 59B in a length corresponding to the wide trigger areas Aa2 and Ab2, the dead zones in which the trigger claws 59A and 59B do not act on the cereals in the wide trigger areas Aa2 and Ab2. Can be prevented from being formed. As a result, while causing each of the raising regions Aa2 and Ab2 of the left and right pulling devices 22A and 22B to be wide enough to allow passage of the two rows of wheat straw, the right and left pulling devices 22A and 22B are surely caused to cause Can be done.
 ちなみに、3条刈りの作業走行時と4条刈りの作業走行時とにかかわらず、常に2条の穀稈が供給される左側の引起装置22Aのみを、その引き起こし領域Aa2の左右幅Waが、最大2条の穀稈の引き起こしに対応する幅広になり、かつ、その引起爪59Aが、幅広の引き起こし領域Aa2に対応する長尺になるように構成してもよい。 By the way, regardless of the time when the three-row mowing operation is running or the time when the 4-row mowing work is running, only the left pulling device 22A to which two rows of cereals are always supplied is caused, and the left and right width Wa of the area Aa2 is increased. You may comprise so that it may become wide corresponding to the raise of a maximum of 2 grain ridges, and the raising nail | claw 59A may become long corresponding to the wide raising area | region Aa2.
 図2、図5および図7~9に示すように、刈刃駆動装置70は、刈取搬送部3の右側端に位置するように中間部材35の右端部に配備してある。これにより、刈刃駆動装置70を刈取搬送部3の左右中央側に配備する場合に招く虞のある、刈り取り後の穀稈が刈刃駆動装置70に絡み付く不都合や、刈刃駆動装置70を刈取搬送部3の左側端に配備する場合に招く虞のある、走行車体1の左外側方のみに未刈りの作物Cxが存在する作業頻度の高い回り刈りの作業走行時に、その未刈りの作物Cxが刈刃駆動装置70に絡み付く不都合の発生を未然に回避することができる。 As shown in FIGS. 2, 5 and 7 to 9, the cutting blade driving device 70 is arranged at the right end of the intermediate member 35 so as to be positioned at the right end of the cutting and conveying unit 3. As a result, there is an inconvenience that the harvested culm becomes entangled with the cutting blade driving device 70, which may be caused when the cutting blade driving device 70 is arranged on the left and right center side of the cutting conveyance unit 3, and the cutting blade driving device 70 is cut. An uncut crop Cx that has a high work frequency when there is an uncut crop Cx that exists only on the left outer side of the traveling vehicle body 1 and that may be incurred when deployed at the left end of the transport unit 3. Therefore, it is possible to avoid the occurrence of inconveniences that are entangled with the blade driving device 70.
 また、供給搬送装置25を、穀稈通過部27に掻き込み搬送された穀稈を車体左側の脱穀装置4に向けて供給搬送するように刈取搬送部3における左寄りの位置に配備することにより、その左側が重くなる刈取搬送部3の右側端に、比較的に重量の大きい刈刃駆動装置70を配備することにより、刈取搬送部3の左右バランスを向上させることができる。 In addition, the supply and transport device 25 is arranged at a position on the left side in the harvesting and transporting unit 3 so as to supply and transport the cereal that has been scraped and transported to the cereal passing unit 27 toward the threshing device 4 on the left side of the vehicle body. By providing a relatively heavy cutting blade driving device 70 at the right end of the cutting and conveying unit 3 whose left side is heavy, the right and left balance of the cutting and conveying unit 3 can be improved.
 刈取搬送部3の右側端には、刈刃駆動装置70を覆う板金製のカバー111を配備してある。カバー111は、右分草部材21Bを中間部材35の右端部に連結する3本のボルト112のうち、上側の2本のボルト112を利用して、中間部材35の右端部に、右分草杆99Bとともに共締め連結してある。 A sheet metal cover 111 that covers the cutting blade driving device 70 is provided at the right end of the cutting and conveying unit 3. The cover 111 uses the upper two bolts 112 among the three bolts 112 that connect the right weed member 21B to the right end of the intermediate member 35, and the right weed at the right end of the intermediate member 35. It is connected together with と と も に 99B.
 これにより、走行車体1の右外側方にも未刈りの作物Cyが存在する中割りの作業走行時には、右分草杆99Bおよびカバー111により、その車体右外側方の未刈り作物Cyが刈刃駆動装置70に絡み付く虞を未然に回避することができる。 As a result, during the middle-distance work traveling in which the uncut crop Cy is also present on the right outer side of the traveling vehicle body 1, the uncut crop Cy on the right outer side of the vehicle body is cut by the right weed rod 99 </ b> B and the cover 111. The possibility of getting entangled with the drive device 70 can be avoided in advance.
 また、右分草部材21Bと右分草杆99Bとカバー111とを、中間部材35の右端部に個々にボルト連結する場合に比較して、組み付け製の向上を図ることができる。しかも、右分草杆99Bやカバー111の交換を行う場合には、右分草部材21Bが中間部材35の右端部から完全に取り外されることを防止しながら、それらの交換を行うことができる。 Further, as compared with the case where the right weed member 21B, the right weed ridge 99B, and the cover 111 are individually bolted to the right end portion of the intermediate member 35, the assembly can be improved. Moreover, when exchanging the right weed ridge 99B and the cover 111, they can be exchanged while preventing the right weed member 21B from being completely removed from the right end of the intermediate member 35.
 図2~4に示すように、走行車体1の前部右側端に位置するサイドフレーム113は、その前半部を、前端側ほど右側のクローラ13Bの右端部13Baに近づくように車体左右方向に傾斜させてある。これにより、走行車体1の右外側方にも未刈りの作物Cyが存在する中割りの作業走行時には、サイドフレーム113の外側面113aを、車体右外側方の未刈り作物Cyを車体右外側方に案内する案内面として機能させることができる。その結果、走行車体1の右外側方に存在する未刈り作物Cyの車体内方側への倒伏を右分草杆99Bとともに阻止することができる。 As shown in FIGS. 2 to 4, the side frame 113 located at the front right side end of the traveling vehicle body 1 is inclined in the left-right direction of the vehicle body so that the front half side approaches the right end portion 13Ba of the crawler 13B on the right side toward the front end side. I'm allowed. As a result, during the middle-distance work traveling in which the uncut crop Cy is also present on the right outer side of the traveling vehicle body 1, the outer surface 113a of the side frame 113 is placed on the uncut crop Cy on the right outer side of the vehicle body. It can be made to function as a guide surface for guiding. As a result, the lodging of the uncut crop Cy existing on the right outer side of the traveling vehicle body 1 toward the vehicle inner side can be prevented together with the right weed 99B.
 ところで、左右の掻込搬送装置24A,24Bにおいて、左右の掻込搬送機構71A,71Bは、ゴム製の掻込ベルト74A,74Bによって穀稈の掻き込み搬送を行なうことにより、刈り取り前の穀稈に作用した場合には、掻込ベルト74A,74Bの突出部74a,74bが、刈り取り前の穀稈の強度に負けて変形し、この変形により、その穀稈が刈り取られるまでの間、その穀稈を穀稈通過部27に向けて掻き込み搬送しなくなる。また、このときの作業走行により、刈り取り前の穀稈を車体前方に向けて押し曲げるようになる。 By the way, in the left and right scraping and transporting devices 24A and 24B, the left and right scraping and transporting mechanisms 71A and 71B perform the scraping and transporting of the culm by the rubber scraping belts 74A and 74B, so In this case, the protrusions 74a and 74b of the take-up belts 74A and 74B are deformed by losing the strength of the culm before cutting, and until the culm is trimmed by this deformation, The rice cake is not scraped and conveyed toward the grain rice cake passage part 27. In addition, by the operation traveling at this time, the cereal before cutting is pushed and bent toward the front of the vehicle body.
 そして、このように押し曲げられた穀稈が、刈取装置23の刈り取り位置に達して刈り取られると、その刈り取りとともに、車体前方に向けて押し曲げられた状態からまっすぐの状態に戻ろうとする復元作用により、左右の掻込搬送機構71A,71Bから離れる車体前方側に飛び出して、左右の掻込搬送機構71A,71Bの搬送領域から外れて、刈取装置12の前方にこぼれ落ちることがある。 Then, when the cereals pushed and bent in this way reach the cutting position of the cutting device 23 and are cut, the restoring action is made to return to the straight state from the pushed and bent state along with the cutting. As a result, it may jump out to the front side of the vehicle body away from the left and right scraping and transporting mechanisms 71A and 71B, deviate from the transport area of the left and right scraping and transporting mechanisms 71A and 71B, and spill out in front of the reaping device 12.
 このような現象が発生すると、刈取装置12の前方にこぼれ落ちた穀稈は、作業走行に伴って左右の掻込搬送機構71A,71Bの搬送領域に向けて次々と導入される後続の未刈りの穀稈により、刈取装置12の刈り取り位置に押し戻され、その株元側が、未刈りの穀稈とともに再び刈り取られることになる。 When such a phenomenon occurs, the grain spills spilled forward in front of the reaping device 12 are successively introduced to the transport areas of the left and right scraping transport mechanisms 71A and 71B as the work travels. The pestle is pushed back to the reaping position of the reaping device 12, and the stock side is reaped together with the unreached culms.
 このような穀稈の二度刈りが発生すると、穀稈の稈長が不揃いになり、この不揃いに起因して、穀稈を脱穀装置4に向けて搬送する際の穂先側の揃いが悪くなって、脱穀装置4での脱穀処理の際に扱き残しが発生しやすくなり、結果、穀粒回収効率の低下を招きやすくなる。 When such cereals are cut twice, the culm lengths of the cereals become uneven, and due to this unevenness, the alignment on the tip side when conveying the cereal toward the threshing device 4 becomes worse. In the threshing process in the threshing apparatus 4, unhandled items are likely to occur, and as a result, the grain recovery efficiency is likely to be reduced.
 そこで、図8、図9、図13および図14に示すように、このコンバインでは、左右の掻込搬送装置24A,24Bにおける左右の掻込搬送機構71A,71Bを、それらの直線搬送経路114A,114Bの車体前後方向に対する車体左右方向への傾斜角θa,θbが同じになるように構成してある。また、左側の掻込搬送機構71Aの直線搬送経路114Aと右側の掻込搬送機構71Bの直線搬送経路114Bとの挟角θAが、左側の掻込搬送機構71Aの直線搬送経路114Aと供給搬送装置25における株元挟持搬送機構82の直線搬送経路115との挟角θBよりも大きくなるように、左右の掻込搬送機構71A,71Bおよび供給搬送装置25の姿勢を設定してある。 Therefore, as shown in FIGS. 8, 9, 13 and 14, in this combine, the left and right scratch conveying mechanisms 71A and 71B in the left and right scratch conveying devices 24A and 24B are connected to their linear conveying paths 114A, The inclination angles θa and θb in the lateral direction of the vehicle body with respect to the longitudinal direction of the vehicle body 114B are configured to be the same. In addition, the angle θA between the straight conveyance path 114A of the left-side scratch conveyance mechanism 71A and the straight conveyance path 114B of the right-side scratch conveyance mechanism 71B is equal to the straight conveyance path 114A of the left-side scratch conveyance mechanism 71A and the supply conveyance device. The postures of the left and right scraping transport mechanisms 71A and 71B and the supply transport device 25 are set so as to be larger than the sandwiching angle θB with the straight transport path 115 of the stock holding and transport mechanism 82 at 25.
 このように左右の掻込搬送機構71A,71Bの姿勢を設定すると、それらの直線搬送経路114A,114Bを、刈取装置23の上方において、複数の可動刃68および固定刃69を左右方向に一直線状に連続して並ぶように整列配置することにより、左右方向に一直線状に並んで位置するようになる各可動刃68および固定刃69の刈り取り位置に対して、それらの刈り取り位置に略沿った状態で位置させることができる。 When the postures of the left and right scraping and conveying mechanisms 71A and 71B are set as described above, the plurality of movable blades 68 and the fixed blades 69 are arranged in a straight line in the left and right direction on the straight conveying paths 114A and 114B above the reaping device 23. Are arranged so that they are arranged in a row in a straight line, and the cutting positions of the movable blades 68 and the fixed blades 69 that are positioned in a straight line in the left-right direction are substantially along the cutting positions. Can be positioned at.
 これにより、左右の掻込搬送装置24A,24Bが、刈取装置23による刈り取り前の穀稈に作用することを効果的に抑制することができ、左右の掻込搬送装置24A,24Bが刈り取り前の穀稈に作用することに起因した穀粒回収効率の低下を効果的に抑制することができる。 Thereby, it is possible to effectively suppress the left and right scavenging and conveying devices 24A and 24B from acting on the culm before the cutting by the reaping device 23, and the left and right scavenging and conveying devices 24A and 24B before the reaping. The fall of the grain collection | recovery efficiency resulting from acting on a grain kernel can be suppressed effectively.
 また、刈取装置23による刈り取り直後の穀稈を、左右の掻込搬送装置24A,24Bによって素早く穀稈通過部27に向けて掻き込み搬送することができ、その結果、左右の掻込搬送装置24A,24Bによる穀稈の掻き込み搬送効率を向上させることができる。 In addition, the culm immediately after cutting by the reaping device 23 can be quickly scraped and conveyed toward the culm passing portion 27 by the left and right scraping and transporting devices 24A and 24B, and as a result, the left and right scraping and transporting device 24A. , 24B can improve the scraping and conveying efficiency of the cereal.
 図8および図13に示すように、左右の掻込搬送装置24A,24Bにおいて、それらの案内部材73A,73Bには、刈取搬送部3の左右の端部から対応する左右のパッカ72A,72Bの回転中心に向けて延出する直線案内部73a,73bを備えてある。各直線案内部73a,73bは、車体前後方向と直行する横一直線状に形成してある。 As shown in FIGS. 8 and 13, in the left and right scraping and conveying devices 24 </ b> A and 24 </ b> B, the guide members 73 </ b> A and 73 </ b> B are provided with the left and right packers 72 </ b> A and 72 </ b> B corresponding to the left and right end portions of the cutting and conveying unit 3. Linear guide portions 73a and 73b extending toward the center of rotation are provided. Each linear guide part 73a, 73b is formed in the horizontal straight line shape orthogonal to the vehicle body front-back direction.
 これにより、左右の案内部材73A,73Bの直線案内部73a,73bが、作業走行時に、刈り取り前の穀稈に作用して、その穀稈を車体前方に向けて押し曲げることを防止することができる。その結果、その押し曲げられた穀稈が、刈り取りとともに、押し曲げ状態からの復元作用により、刈取装置12の前方にこぼれ落ちて二度刈りされる虞を未然に回避することができる。 Thereby, it is possible to prevent the straight guide portions 73a and 73b of the left and right guide members 73A and 73B from acting on the culm before cutting and pushing and bending the cereal toward the front of the vehicle body during work travel. it can. As a result, it is possible to avoid the possibility that the pushed and bent cereal is spilled to the front of the reaping device 12 and cut twice due to the restoring action from the pushed and bent state.
 図3および図14に示すように、供給搬送装置25は、その搬送始端部25bが車体正面視で搭乗運転部2と重なり合うように、その搬送姿勢を設定してある。これにより、刈取搬送部3を2枠4条刈り仕様で、左分草部材21Aの分草始端21Aaと左側のクローラ13Aの左端部13Aaとの車体左右方向での位置が一致し、かつ、右分草部材21Bの分草始端21Baと右側のクローラ13Bの右端部13Baとの車体左右方向での位置が略一致するように構成したことにより、走行車体1の左右中間部に位置するようになる穀稈通過部27に対して、供給搬送装置25の搬送始端部25bを、穀稈通過部27を通過した穀稈を直に受け取ることが可能な穀稈通過部27の直後方の位置に位置させることができる。 As shown in FIG. 3 and FIG. 14, the transporting posture of the supply transport device 25 is set so that the transport start end portion 25 b overlaps the boarding operation unit 2 when viewed from the front of the vehicle body. As a result, the cutting and conveying section 3 has a two-frame, four-saw cutting specification, and the positions of the left weeding start end 21Aa of the left weeding member 21A and the left end 13Aa of the left crawler 13A in the left-right direction of the vehicle body match, By configuring so that the weed starting end 21Ba of the weeding member 21B and the right end 13Ba of the right crawler 13B in the left-right direction of the vehicle body substantially coincide with each other, it is positioned at the left-right intermediate portion of the traveling vehicle body 1. With respect to the cereal passing part 27, the conveyance start end 25b of the supply and transport device 25 is positioned immediately after the cereal passing part 27 capable of directly receiving the cereal passing through the cereal passing part 27. Can be made.
 つまり、左右の掻込搬送装置24A,24Bと供給搬送装置25との間に、穀稈の受け渡しを中継する補助搬送装置を装備することなく、2枠4条刈り仕様に構成した刈取搬送部3に適した供給搬送構造を得ることができる。 That is, the cutting and conveying unit 3 configured to have a two-frame four-cutting specification without equipping an auxiliary conveying device that relays the delivery of cereals between the left and right scratch conveying devices 24A and 24B and the supply and conveying device 25. Can be obtained.
 搭乗運転部2は、供給搬送装置25の搬送始端部25bと車体正面視で重なり合うサイドパネル15の前端部に、供給搬送装置25の搬送始端部25bが入り込むことを許容する凹部2aを形成してある。 The boarding operation unit 2 forms a recess 2a that allows the transfer start end 25b of the supply transfer device 25 to enter the front end of the side panel 15 that overlaps with the transfer start end 25b of the supply transfer device 25 when viewed from the front of the vehicle body. is there.
 供給搬送装置25は、その搬送始端部25bが搭乗運転部2の凹部2aに入り込むように、車体前後方向に対する株元挟持搬送機構82の直線搬送経路115の車体左右方向への傾斜角θc、および、車体前後方向に対する穂先係止搬送機構83の直線搬送経路116の車体左右方向への傾斜角θdを大きくしてある。 The supply conveyance device 25 has an inclination angle θc in the vehicle body left-right direction of the straight conveyance path 115 of the stock holding and conveying mechanism 82 with respect to the vehicle body longitudinal direction so that the conveyance start end portion 25b enters the recess 2a of the boarding operation unit 2, and The inclination angle θd of the linear conveyance path 116 of the tip locking conveyance mechanism 83 with respect to the longitudinal direction of the vehicle body in the lateral direction of the vehicle body is increased.
 これにより、搭乗運転部2に凹部2aを形成しない場合に比較して、供給搬送装置25の搬送始端部側を搭乗運転部2に近づけることができ、これにより、供給搬送装置25の車体前後方向での長さを短くすることができ、コンバイン全体としての全長を短くすることができる。 Thereby, compared with the case where the recessed part 2a is not formed in the boarding operation part 2, the conveyance start end part side of the supply conveyance apparatus 25 can be brought close to the boarding operation part 2, and, thereby, the vehicle body front-back direction of the supply conveyance apparatus 25 is obtained. Can be shortened, and the overall length of the combine as a whole can be shortened.
 また、供給搬送装置25の搬送始端側ほど搭乗運転部2に更に近づくようになり、これにより、供給搬送装置25の支持フレーム90に備えた扱き深さ調節用の操作レバー98も、搭乗運転部2に更に近づくようになり、結果、搭乗運転部2からの扱き深さ調節用の操作レバー98の操作が更に行いやすくなる。 Further, the closer to the boarding operation unit 2 is, the closer to the transport start end side of the supply transport device 25, the operation lever 98 for adjusting the handling depth provided in the support frame 90 of the supply transport device 25 is also provided. As a result, the operation lever 98 for adjusting the handling depth from the boarding operation unit 2 becomes easier to operate.
 ところで、供給搬送装置25の車体前後方向に対する車体左右方向への傾斜角θc,θdを大きくすると、供給搬送装置25が左側の掻込搬送機構71Aに近づくことになる。そのため、供給搬送装置25により搬送する穀稈の株元側が左側の掻込搬送機構71Aに接触して、その穀稈の搬送姿勢が乱れる不都合を招く虞がある。 By the way, when the inclination angles θc and θd of the supply / conveyance device 25 in the lateral direction of the vehicle body with respect to the longitudinal direction of the vehicle body are increased, the supply / conveyance device 25 approaches the left-side scraping conveyance mechanism 71A. Therefore, there is a possibility that the stocker side of the cereals conveyed by the supply and transport device 25 comes into contact with the left-side scraping and conveying mechanism 71A, resulting in inconvenience that the conveying posture of the cereals is disturbed.
 そこで、図1、図2、図5~7および図9に示すように、このコンバインでは、左側の掻込搬送機構71Aを右側の掻込搬送機構71Bよりも高さ位置が低くなるように配置してある。これにより、供給搬送装置25により搬送する穀稈の株元側が左側の掻込搬送機構71Aに接触して、その穀稈の搬送姿勢が乱れることを防止することができ、その乱れに起因して、供給搬送装置25により穀稈を脱穀装置4に向けて搬送する際の穂先側の揃いが悪くなり、脱穀装置4での脱穀処理において扱き残しが発生しやすくなる、といった穀粒回収率の低下を防止することができる。 Therefore, as shown in FIG. 1, FIG. 2, FIG. 5 to FIG. 7 and FIG. 9, in this combine, the left scraping transport mechanism 71A is disposed at a lower height than the right scraping transport mechanism 71B. It is. As a result, the stocker side of the corn straw conveyed by the supply conveyance device 25 can be prevented from coming into contact with the left feeding and conveying mechanism 71A, and the conveying posture of the corn straw can be prevented from being disturbed. The grain recovery rate is reduced such that the supply side of the cereals is transported toward the threshing device 4 by the feeding / conveying device 25, and the handling of the threshing process in the threshing device 4 is likely to occur. Can be prevented.
 また、左側の掻込搬送機構71Aを2条用に構成し、かつ、供給搬送装置25の車体前後方向に対する車体左右方向への傾斜角θc,θdを大きくすると、左側の引起枠26Aで刈り取った穀稈は、左側の掻込搬送機構71Aと供給搬送装置25によって略U字状に搬送されるようになる。そのため、その略U字状に搬送される穀稈の搬送方向切り換え地点となる穀稈通過部27においては、その穀稈の株元側が遠心力によって大きく振り回される傾向にある。 Further, when the left side scraping / conveying mechanism 71A is configured for two lines and the inclination angles θc and θd of the supply / conveyance device 25 in the lateral direction of the vehicle body with respect to the longitudinal direction of the vehicle body are increased, the left pulling frame 26A is used for trimming. The cereals are transported in a substantially U shape by the left-handed scraping transport mechanism 71A and the supply transport device 25. For this reason, in the culm passing section 27, which is a transfer direction switching point of the culm that is conveyed in a substantially U shape, the stocker side of the culm tends to be greatly swung by centrifugal force.
 そこで、図1、図2、図6~10および図13に示すように、このコンバインでは、延出部材34と中間部材35との間に前後向きの連結部35Aを介装して、延出部材34を穀稈通過部27から車体後方側に離すことにより、延出部材34と中間部材35との間に、左右の掻込搬送装置24A,24Bから供給搬送装置25に受け渡す穀稈の株元側の通過を許容する前後幅の広い受け渡し経路117を形成してある。 Therefore, as shown in FIGS. 1, 2, 6 to 10, and 13, in this combine, the extending portion 34 and the intermediate member 35 are provided with a front-rear connecting portion 35 A interposed therebetween to extend the combine. By separating the member 34 from the grain passer 27 to the rear side of the vehicle body, between the extending member 34 and the intermediate member 35, A wide delivery path 117 that allows passage on the stock market side is formed.
 これにより、穀稈通過部27において、穀稈の株元側が遠心力によって大きく振り回されるようになったとしても、その穀稈の株元側が延出部材34の延出端に接触することを防止することができ、その接触による穀稈の搬送姿勢の乱れに起因して穀稈の穂先側の揃いが悪くなり、脱穀装置4での脱穀処理において扱き残しが発生しやすくなる、といった穀粒回収率の低下を防止することができる。 As a result, even if the cereal stock side is greatly swung by the centrifugal force in the cereal passing portion 27, the stock side of the cereal is prevented from contacting the extending end of the extending member 34. Kernel recovery that can be performed, and the grain tip side of the cereal is not aligned properly due to the contact posture of the cereal that is caused by the contact, and unhandled residue is likely to occur in the threshing process in the threshing device 4 A decrease in rate can be prevented.
 また、延出部材34を、穀稈通過部27よりも刈取搬送部3の左端側に位置するように配置してある。これにより、穀稈通過部27において、遠心力によって大きく振り回される穀稈の株元側が、延出部材34の延出端に接触することをより確実に防止することができ、その接触に起因した穀粒回収率の低下をより確実に防止することができる。 Further, the extending member 34 is arranged so as to be located on the left end side of the cutting and conveying unit 3 with respect to the grain passing portion 27. Thereby, in the corn straw passage part 27, it can prevent more reliably that the stock source side of the corn straw greatly shaken by the centrifugal force contacts the extension end of extension member 34, and resulted from the contact A drop in the grain recovery rate can be prevented more reliably.
 さらに、左右の掻込搬送装置24A,24Bの案内部材73A,73Bを、穀稈通過部27を通過する穀稈の株元側を供給搬送装置25に向けて案内するように形成し、かつ、左側の案内部材73Aの案内終端部73cを支持部材36に固定し、右側の案内部材73Aの案内終端部73dを延出部材34の延出端部に固定してある。 Furthermore, the guide members 73A and 73B of the left and right scraping and conveying devices 24A and 24B are formed so as to guide the stock source side of the cereal passing through the cereal passing portion 27 toward the supply conveying device 25, and The guide end portion 73c of the left guide member 73A is fixed to the support member 36, and the guide end portion 73d of the right guide member 73A is fixed to the extending end portion of the extending member 34.
 これにより、穀稈通過部27において、穀稈の株元側が遠心力によって大きく振り回されるようになったとしても、その振り回しを右側の案内部材73Bによって効果的に抑制することができ、その穀稈の株元側を、左右の案内部材73A,73Bによって供給搬送装置25の株元挟持搬送機構82に速やかにかつ確実に受け渡すことができる。その結果、受け渡し不良に起因した穀稈詰まりや、受け渡し不良による穀稈の搬送姿勢の乱れに起因した穀粒回収率の低下を防止することができる。 As a result, even if the stock side of the cereal is greatly swung by the centrifugal force in the cereal passing portion 27, the turning can be effectively suppressed by the right guide member 73B, and the Can be quickly and reliably delivered to the stock holding and transporting mechanism 82 of the supply and transport device 25 by the left and right guide members 73A and 73B. As a result, it is possible to prevent the grain recovery rate from being reduced due to clogging of cereals due to poor delivery and the disturbance of the posture of conveying cereals due to poor delivery.
 図6、図9および図13に示すように、連結部35Aの上方には、左右の掻込搬送装置24A,24Bから供給搬送装置25に受け渡す穀稈の下端を下方から受け止め支持する支持プレート118を、延出部材34の延出端から中間部材35にわたるように装備してある。 As shown in FIGS. 6, 9, and 13, above the connecting portion 35 </ b> A, a support plate that receives and supports the lower end of the cereals delivered from the left and right scraping and conveying devices 24 </ b> A and 24 </ b> B to the supply and conveying device 25 from below. 118 is provided so as to extend from the extending end of the extending member 34 to the intermediate member 35.
 これにより、左右の掻込搬送装置24A,24Bから供給搬送装置25に受け渡す穀稈の株元側を揃えやすくすることができる。その結果、穀稈の穂先側が揃うようになり、脱穀装置4での脱穀処理において扱き残しが発生しにくくなり、穀粒回収率を向上させることができる。 Thereby, it is possible to easily align the stock side of the cereals delivered from the left and right scraping and conveying devices 24A and 24B to the supply and conveying device 25. As a result, the tip side of the cereal grains comes to be aligned, and it is difficult for unhandled items to be generated in the threshing process in the threshing device 4, and the grain recovery rate can be improved.
[刈取搬送部の別形態]
 図19は刈取搬送部3の別の形態を示す刈取搬送部3の左側面図、図20は刈取搬送部3の別の形態を示す刈取搬送部3の正面図である。これらの図に示すように、刈取搬送部3は、左分草部材21Aを交換することにより、その左側端部における左分草具51Aと左側の引起装置22Aとの間に、駆動式の分草装置139を装備することができる。
[Another form of cutting and conveying section]
FIG. 19 is a left side view of the cutting and conveying unit 3 showing another form of the cutting and conveying unit 3, and FIG. 20 is a front view of the cutting and conveying unit 3 showing another form of the cutting and conveying unit 3. As shown in these drawings, the cutting and conveying unit 3 exchanges the left weeding member 21A, so that the drive type separating member 21A is disposed between the left weeding tool 51A at the left end and the left pulling device 22A. A grass device 139 can be equipped.
 図5、図19および図20に示すように、分草装置139は、左側の引起装置22Aの入力軸53Aからベベルギヤ式の補助伝動機構140を介して取り出した動力により駆動することができる。そして、その駆動により、その上部に配備した駆動スプロケット141と、その下部に配備した従動スプロケット142とにわたって回し掛けた無端チェーン143が回動することにより、その無端チェーン143に一定ピッチで整列配備した複数の引起爪144により、刈取搬送部3の作業幅内最左の作物Caと、この作物Caと隣り合う左側の作業幅外の作物Cxとを梳き分ける。 As shown in FIGS. 5, 19, and 20, the weeding device 139 can be driven by the power extracted from the input shaft 53A of the left pulling device 22A via the bevel gear type auxiliary transmission mechanism 140. Then, by driving, the endless chain 143 turned over the driving sprocket 141 provided in the upper part and the driven sprocket 142 provided in the lower part is rotated, so that the endless chain 143 is aligned and arranged at a constant pitch. The plurality of raising claws 144 separate the leftmost crop Ca within the work width of the cutting and conveying unit 3 and the crop Cx outside the left work width adjacent to the crop Ca.
 つまり、左分草具51Aと左側の引起装置22Aとの間に駆動式の分草装置139を装備することにより、刈取搬送部3の作業幅内最左の作物Caと、この作物Caと隣り合う左側の作業幅外の作物Cxとの分草精度および分草効率を向上させることができる。この効果は、作物Cの倒伏が激しい圃場で収穫作業を行う場合に特に顕著に現れる。 That is, by installing the drive type weeding device 139 between the left weeding tool 51A and the left pulling device 22A, the leftmost crop Ca within the working width of the cutting and conveying unit 3 and the adjacent crop Ca. It is possible to improve the weeding accuracy and weeding efficiency with the crop Cx outside the working width on the left side. This effect is particularly prominent when the harvesting operation is performed in a field where the crop C is heavily laid down.
 分草装置139は、車体左右方向の車体内方に向けて傾倒する傾斜姿勢で装備してある。これにより、刈取搬送部3の作業幅内最左の作物Caと、この作物Caと隣り合う左側の作業幅外の作物Cxとを梳き分けながら、作業幅内最左の作物Caの穂先側を、左側の引起装置22Aの引き起こし領域Aa1に向けて梳き寄せることができる。 The weeding device 139 is equipped with an inclined posture that tilts toward the inside of the vehicle body in the lateral direction of the vehicle body. Thereby, while separating the leftmost crop Ca within the work width of the cutting and conveying unit 3 and the crop Cx outside the left work width adjacent to the crop Ca, the tip side of the leftmost crop Ca within the work width is The left pulling device 22A can be pulled toward the raising area Aa1.
 これにより、左側の引起装置22Aによる作物Cの引き起こし精度および引き起こし効率を向上させることができる。この効果は、左側の引起装置22Aによって2条の作物Cを引き起こす場合に特に顕著に現れる。 This makes it possible to improve the accuracy and efficiency of the crop C caused by the pulling device 22A on the left side. This effect is particularly prominent when the left pulling device 22A causes two crops C.

[第2実施形態]
 次に、図21~28を参照しながら、第2実施形態について説明する。以下では主として第1実施形態との相違点について説明し、第1実施形態との共通点については同一の符号を付することによって説明を省略する。
[Second Embodiment]
Next, a second embodiment will be described with reference to FIGS. Hereinafter, differences from the first embodiment will be mainly described, and common points with the first embodiment will be denoted by the same reference numerals and description thereof will be omitted.
 図21~26に示すように、刈取搬送部3と脱穀装置4との間には、供給搬送装置25から挟持搬送機構31に株元側が受け渡された穀稈の穂先側を受けながら、挟持搬送機構31の挟持搬送に伴って、その穂先側を脱穀装置の供給口4aに案内する穂先ガイド119を配備してある。そして、運転座席19の左真横に脱穀装置4の供給口4aが位置するように、具体的には、運転座席19の左真横における運転座席19の前端19aと背凭れ19bとの間の位置に脱穀装置4の供給口4aが位置するように構成してある。 As shown in FIGS. 21 to 26, the cutting and transporting unit 3 and the threshing device 4 are sandwiched while receiving the tip side of the cereal that has been transferred from the supply and transport device 25 to the sandwiching and transporting mechanism 31. Along with the nipping and transporting of the transport mechanism 31, a tip guide 119 for guiding the tip side to the supply port 4a of the threshing apparatus is provided. And specifically, in the position between the front end 19a of the driver's seat 19 and the backrest 19b in the right side of the driver's seat 19 so that the supply port 4a of the threshing device 4 is positioned right next to the driver's seat 19. It is comprised so that the supply port 4a of the threshing apparatus 4 may be located.
 これにより、供給搬送装置25の搬送終端部25aと脱穀装置4の供給口4aとの間に位置する穂先ガイド119が、運転座席19の左真横よりも車体前方側に位置するようになる。 Thus, the tip guide 119 located between the conveyance end portion 25a of the supply conveyance device 25 and the supply port 4a of the threshing device 4 is positioned on the front side of the vehicle body with respect to the left side of the driver seat 19.
 その結果、作業走行中においては、収穫する作物Cに対する適正位置から車体位置が外れないように車体の前方を目視しながらも、そのときの視界内に、供給搬送装置25の搬送終端部25aと脱穀装置4の供給口4aとの間を入れることができる。つまり、車体の前方を目視しながらも、挟持搬送機構31により搬送され、穂先ガイド119により案内される穀稈の搬送姿勢の搬送姿勢を監視することができる。 As a result, while working, while looking at the front of the vehicle body so that the vehicle body position does not deviate from the appropriate position for the crop C to be harvested, the conveyance terminal portion 25a of the supply conveyance device 25 is within the field of view at that time. A space between the threshing device 4 and the supply port 4a can be inserted. That is, it is possible to monitor the conveying posture of the corn straw that is conveyed by the clamping conveying mechanism 31 and guided by the tip guide 119 while visually checking the front of the vehicle body.
 また逆に、挟持搬送機構31により搬送され、穂先ガイド119により案内される穀稈の搬送姿勢をより確実に把握するために、供給搬送装置25の搬送終端部25aと脱穀装置4の供給口4aとの間を直視する場合には、そのときの視界内に車体前方の光景を入れることができる。つまり、挟持搬送機構31により搬送され、穂先ガイド119により案内される穀稈を直視した場合であっても、収穫する作物Cに対する適正位置から車体位置が外れる虞を回避しやすくなる。 Conversely, in order to more reliably grasp the transport posture of the cereals that are transported by the sandwiching transport mechanism 31 and guided by the tip guide 119, the transport terminal portion 25a of the supply transport device 25 and the supply port 4a of the threshing device 4 are used. When looking directly between the two, a scene in front of the vehicle body can be put in the field of view at that time. That is, it is easy to avoid the possibility that the vehicle body position is deviated from the appropriate position for the crop C to be harvested even when the grain straws conveyed by the clamping conveyance mechanism 31 and guided by the tip guide 119 are viewed directly.
 そして、供給搬送装置25の搬送終端部25aと脱穀装置4の供給口4aとの間において穀稈の穂先遅れが発生した場合には、その穀稈の穂先側を運転者が手で脱穀装置側に掻き寄せることにより、穀稈の穂先遅れを簡単に解消することができ、穂先遅れに起因した搬送詰まりや穂切れなどの誘発を回避することができる。 And when the tip end of the grain culm occurs between the conveying terminal part 25a of the supply transport device 25 and the supply port 4a of the threshing device 4, the driver manually hands the tip side of the cereal masher side It is possible to easily eliminate the delay in the tip of the cereal, and to avoid the clogging of conveyance and the breakage of the ear due to the delay in the tip.
 図24~26に示すように、穂先ガイド119は、供給搬送装置25の後部から後方に向けて延出するように供給搬送装置25に連結したゴム製の第1ガイド120と、脱穀装置4の前壁121から前方に向けて延出するように前壁121に装備した板金製の第2ガイド122とを、第1ガイド120が第2ガイド122によって受け止め支持された状態となるように重合させることで、刈取搬送部3の昇降揺動を許容しながら刈取穀稈の穂先側を円滑に案内するように構成してある。 As shown in FIGS. 24 to 26, the tip guide 119 includes a first guide 120 made of rubber connected to the supply conveyance device 25 so as to extend rearward from the rear portion of the supply conveyance device 25, and the threshing device 4 The second guide 122 made of sheet metal mounted on the front wall 121 so as to extend forward from the front wall 121 is superposed so that the first guide 120 is received and supported by the second guide 122. Thus, the cutting tip side of the harvested cereal rice cake is smoothly guided while allowing the swinging conveying unit 3 to move up and down.
 第1ガイド120は、後下がりの傾斜面からなる案内面120aを有するように、供給搬送装置25の後部に連結し、かつ、第2ガイド122により受け止め支持させてある。第2ガイド122は、脱穀装置4の供給口4aの下縁に沿って湾曲または傾斜するように形成してある。 The first guide 120 is connected to the rear portion of the supply / conveyance device 25 so as to have a guide surface 120a composed of a rearwardly inclined surface, and is received and supported by the second guide 122. The second guide 122 is formed to be curved or inclined along the lower edge of the supply port 4a of the threshing device 4.
 第1ガイド120の案内面120aは、その車体左側の端部が第2ガイド122に沿って上向きに傾斜し、その車体右側の端部が第2ガイド122に沿って上向きに湾曲し、その左右の端部の間に位置する中央側の領域が左右方向の高さ位置が同じになる水平領域となるように、かつ、その水平領域が第2ガイド122の底部から上方に離間した位置に位置するように形成してある。 The guide surface 120a of the first guide 120 has an end on the left side of the vehicle body inclined upward along the second guide 122, and an end on the right side of the vehicle body curved upward along the second guide 122. The central region located between the end portions of the second guide 122 is a horizontal region having the same height in the left-right direction, and the horizontal region is located at a position spaced upward from the bottom of the second guide 122. It is formed to do.
 そして、上記の構成を利用して、穂先ガイド119を、その案内面119aの高さ位置が、運転座席19の座面19cの高さ位置と略同じになるように構成してある。具体的には、穂先ガイド119の案内面119aとなる第1ガイド120の案内面120aを、その前端部の高さ位置が、運転座席19の座面19cの高さ位置と略一致し、その後部側の高さ位置が、運転座席19の座面19cの高さ位置から徐々に低くなるように設定してある。 And using the above configuration, the tip guide 119 is configured such that the height position of the guide surface 119a is substantially the same as the height position of the seat surface 19c of the driver seat 19. Specifically, the height position of the front end of the guide surface 120a of the first guide 120, which becomes the guide surface 119a of the tip guide 119, substantially coincides with the height position of the seat surface 19c of the driver seat 19, and thereafter The height position on the part side is set so as to gradually decrease from the height position of the seating surface 19c of the driver seat 19.
 また、運転座席19と穂先ガイド119の間に位置するサイドパネル15は、その上面15aの高さ位置が、運転座席19の座面19cおよび穂先ガイド119の案内面119aの前端部よりも低くなる状態で、運転座席19の座面19cおよび穂先ガイド119の案内面119aの高さ位置と略同じになるように構成してある。 In addition, the side panel 15 positioned between the driver seat 19 and the tip guide 119 has a height position of the upper surface 15a lower than the seat 19c of the driver seat 19 and the front end portion of the guide surface 119a of the tip guide 119. In this state, the height of the seat 19c of the driver's seat 19 and the height of the guide surface 119a of the tip guide 119 is substantially the same.
 これにより、穂先ガイド119の案内面119aを、運転座席19に座った運転者の視界に入りやすく手が届きやすい高さ位置に、サイドパネル15によって遮られることのない状態で位置させることができる。 As a result, the guide surface 119a of the tip guide 119 can be positioned at a height that is easy to enter the field of view of the driver sitting on the driver's seat 19 and not easily blocked by the side panel 15. .
 その結果、供給搬送装置25の搬送終端部25aと脱穀装置4の供給口4aとの間において挟持搬送機構31が搬送する穀稈の搬送姿勢の監視が行いやすくなるとともに、その穀稈に穂先遅れが発生した場合の運転者の手作業による穂先遅れの修正が行いやすくなる。 As a result, it becomes easier to monitor the posture of the cereals conveyed by the pinching and conveying mechanism 31 between the conveying terminal part 25a of the supply and conveying device 25 and the supply port 4a of the threshing device 4, and the tip of the cereal is delayed. This makes it easier to correct the head delay due to the driver's manual operation.
 そして、前述したように、搭乗運転部2の刈取搬送部側の前端部となるサイドパネル15の前端部に凹部2aを形成し、その凹部2aに供給搬送装置25の搬送始端部25bが入り込むように、供給搬送装置25の車体前後方向に対する車体左右方向への傾斜角θc,θdを大きくしたことにより、供給搬送装置25の車体前後方向での長さを短くすることができ、これにより、運転座席19の左真横に脱穀装置4の供給口4aを位置させるのに伴って、供給搬送装置25の搬送終端部25aを車体前方側に変位させる必要が生じても、その変位に伴って刈取搬送部3の全体が車体前方側に変位することや、その変位によって左右の引起装置22A,22Bが搭乗運転部2のフロントパネル14から車体前方側に離れることを防止することができる。 And as above-mentioned, the recessed part 2a is formed in the front-end part of the side panel 15 used as the front-end part by the side of the cutting conveyance part of the boarding operation part 2, and the conveyance start end part 25b of the supply conveyance apparatus 25 enters into the recessed part 2a. In addition, by increasing the inclination angles θc and θd in the lateral direction of the vehicle body with respect to the longitudinal direction of the vehicle body of the supply / conveyance device 25, the length of the supply / conveyance device 25 in the longitudinal direction of the vehicle body can be shortened. Even if it is necessary to displace the conveying terminal end 25a of the supply conveying device 25 to the front side of the vehicle body as the supply port 4a of the threshing device 4 is positioned just to the left of the seat 19, the cutting conveyance is performed in accordance with the displacement. It is possible to prevent the entire portion 3 from being displaced to the front side of the vehicle body and to prevent the left and right pulling devices 22A and 22B from moving away from the front panel 14 of the boarding operation unit 2 to the front side of the vehicle body due to the displacement. it can.
 その結果、刈取搬送部3の全体が車体前方側に変位することに起因してコンバイン全体としての全長が長くなる、あるいは、左右の引起装置22A,22Bが搭乗運転部2のフロントパネル14から車体前方側に離れることにより、各分草具51A~51Cと車体の前方に位置する作物Cとの位置関係などを搭乗運転部2から視認する際に、そのときの視界が左右の引起装置22A,22Bによって遮られる、といった不都合の発生を防止することができる。 As a result, the entire length of the combine as a whole is increased due to the entire cutting and conveying unit 3 being displaced forward of the vehicle body, or the left and right pulling devices 22A and 22B are moved from the front panel 14 of the boarding operation unit 2 to the vehicle body. When viewing the positional relationship between each weeding tool 51A to 51C and the crop C located in front of the vehicle body from the boarding operation unit 2 by moving away from the front side, the visibility at that time is the left and right pulling device 22A, Generation | occurrence | production of the problem of being interrupted by 22B can be prevented.
 なお、図25に示す符号123は脱穀装置4の内部に備えた扱胴であり、扱胴123は、脱穀装置4の内部において、その略全体が運転座席19の座面19cよりも上方に位置するように配備してある。そして、この扱胴123が正面視右回りに回転することにより、脱穀装置4の内部に供給した穀稈の穂先側に脱穀処理を施すことができる。また、図25および図26に示す符号127は、脱穀装置4の供給口4aから内部への穀稈の供給を許容し、かつ、脱穀処理により発生するワラ屑などの脱穀装置4の供給口4aからの吹き出しを阻止する暖簾状でゴム製の供給口カバーである。 In addition, the code | symbol 123 shown in FIG. 25 is the handling cylinder with which the inside of the threshing apparatus 4 was equipped, and the inside of the threshing apparatus 123 is located substantially upwards rather than the seat surface 19c of the driver's seat 19 inside the threshing apparatus 4. It is deployed to do. And the threshing process can be performed to the tip side of the cereal straw supplied to the inside of the threshing device 4 by rotating the handling barrel 123 clockwise in front view. Moreover, the code | symbol 127 shown in FIG.25 and FIG.26 accept | permits supply of the cereals from the supply port 4a of the threshing apparatus 4, and is the supply port 4a of the threshing apparatus 4, such as straw scraps which generate | occur | produces by a threshing process. This is a warm, rubber-like supply port cover that prevents the air from blowing out.
 図示は省略するが、上記の脱穀処理で得た処理物には、脱穀装置4の内部に備えた篩い式や風力式などの選別機構によって選別処理を施す。この選別処理で得た単粒化穀粒は、1番回収部に回収し、1番スクリューにより揚送スクリュー6に向けて搬送する。未単粒化穀粒などは、2番回収部に回収し、2番スクリューにより2番還元装置に搬送し、2番還元装置において再脱穀処理を施した後、選別機構による再選別処理が施されるように、2番還元装置により選別機構に向けて搬送する。切れワラやワラ屑などの塵埃は、脱穀装置4の後端部に形成した排塵口から車外に排出する。脱穀装置4に備えた挟持搬送機構31、扱胴123、選別機構、1番スクリュー、2番スクリュー、および2番還元装置などは、揚送スクリュー6とともに、脱穀クラッチなどを介して伝達されるエンジン9からの動力で作動する。 Although illustration is abbreviate | omitted, the processed material obtained by said threshing process performs a sorting process with sorting mechanisms, such as a sieving type | formula provided in the inside of the threshing apparatus 4, and a wind type. The single grain obtained by this sorting process is collected in the No. 1 recovery part and conveyed toward the lifting screw 6 by the No. 1 screw. Unseparated grains etc. are collected in the No. 2 recovery unit, transported to the No. 2 reduction device by the No. 2 screw, re-threshed in the No. 2 reduction device, and then subjected to the re-sorting process by the sorting mechanism. As described above, the sheet is conveyed toward the sorting mechanism by the second reduction device. Dust such as cut straw and straw waste is discharged out of the vehicle through a dust outlet formed at the rear end of the threshing device 4. The threshing device 4 includes a holding and conveying mechanism 31, a handling cylinder 123, a selection mechanism, a first screw, a second screw, and a second reduction device, which are transmitted together with the lifting screw 6 through a threshing clutch or the like. Operates with power from 9.
 ちなみに、脱穀装置4は、4条刈りの作業走行時での処理量に対応する処理能力を有するように構成してある。 Incidentally, the threshing device 4 is configured to have a processing capacity corresponding to the processing amount at the time of the four-row cutting operation.
 図27はエンジンカバー16の構成を示す要部の縦断背面図、図28はエンジンカバー16の構成を示す要部の横断平面図である。図21~23および図25~28に示すように、エンジンカバー16は、運転座席19を支持する天板124と前後壁125,126とを有するようにコの字状に屈曲形成したカバー本体127に右側壁128などを溶接して、前壁125から右側壁128にわたる風路129を有するように構成してある。 27 is a longitudinal rear view of the main part showing the configuration of the engine cover 16, and FIG. 28 is a transverse plan view of the main part showing the configuration of the engine cover 16.

 補強板225は、平板を複数箇所(2箇所)で異なる方向に折り曲げ成形した側面視で屈曲した形状に構成されている。これにより、屈曲した形状で補強板225の強度を向上しながら、一枚板状の補強板225の前部に斜め前方下方に傾斜した傾斜面225Aを形成でき、補強板225の後部に斜め後方上方に傾斜した取り付け部225Bを形成できる。補強板225の傾斜面225Aが形成された傾斜部には、上下に連通する貫通穴が形成されて、この貫通穴に、段付き形状に成形された円筒状の軸支持部材225Cが内嵌挿入されて固着されている。なお、この実施形態では、折り曲げ成形により補強板225を一枚板状に構成して傾斜面225A等を一体形成した例を示したが、例えば複数の平板を溶接等により接合することで補強板225を一枚板状に構成して傾斜面225A等を形成してもよい。 The reinforcing plate 225 is configured in a bent shape in a side view in which a flat plate is bent at a plurality of locations (two locations) in different directions. Thus, while improving the strength of the reinforcing plate 225 with a bent shape, an inclined surface 225A inclined obliquely forward and downward can be formed at the front portion of the single plate-like reinforcing plate 225, and obliquely rearward at the rear portion of the reinforcing plate 225. The attaching part 225B inclined upward can be formed. A through hole communicating with the upper and lower sides is formed in the inclined portion where the inclined surface 225A of the reinforcing plate 225 is formed, and a cylindrical shaft support member 225C formed into a stepped shape is inserted into the through hole. Has been fixed. In this embodiment, an example in which the reinforcing plate 225 is formed into a single plate by bending and the inclined surface 225A is integrally formed is shown. However, for example, a plurality of flat plates are joined by welding or the like to form the reinforcing plate. The inclined surface 225A or the like may be formed by configuring the 225 into a single plate shape.
 軸支持部材225Cには、上下に連通する穴部が形成されており、この穴部にアーム258を支持する支軸261が上方から内嵌挿入されて、支軸261の先端(下端)のネジ部に円盤状のワッシャを介して下方側からナットが締め付けられ、刈刃駆動機構253のアーム258が補強板225に回動自在に支持されている。これにより、傾斜面225Aと平行な軸支持部材225Cの上面がアーム258のボス部を安定支持する支持面として機能する。なお、軸支持部材225Cを設けずに、補強板225の傾斜面225Aが形成されている傾斜部を板厚の更に厚いものに構成する等して傾斜面225Aに直接的にアーム258を接当支持させ、傾斜面225Aがアーム258のボス部を安定支持する支持面として機能するように構成してもよい。 The shaft support member 225C is formed with a hole portion that communicates with the upper and lower sides. A support shaft 261 that supports the arm 258 is inserted into the hole portion from above, and a screw at the tip (lower end) of the support shaft 261 is inserted. A nut is fastened to the portion from below via a disk-shaped washer, and an arm 258 of the cutting blade drive mechanism 253 is rotatably supported by the reinforcing plate 225. Thus, the upper surface of the shaft support member 225C parallel to the inclined surface 225A functions as a support surface that stably supports the boss portion of the arm 258. In addition, without providing the shaft support member 225C, the inclined portion where the inclined surface 225A of the reinforcing plate 225 is formed has a thicker thickness, for example, and the arm 258 is directly contacted with the inclined surface 225A. The inclined surface 225A may be configured to function as a support surface that stably supports the boss portion of the arm 258.
 補強板225の前端部は、角パイプ状の刈取フレーム215の上面側に固着されている。伝動ケース213には、前方に突出する支持部213aが一体形成されており、この支持部213aに補強板225の取り付け部225Bの下面側が当て付けられ、支持部213aのネジ部に上方からボルトが締め付けられて、補強板225が支持部213aに着脱可能に固定されている。補強板225の前後中央部における下面側には、横長の丸パイプフレーム226の内端側が固着されており、この丸パイプフレーム226の外端側は、外側分草フレーム214後端部の内側部分に固着されている。 The front end of the reinforcing plate 225 is fixed to the upper surface side of the square pipe-shaped cutting frame 215. The transmission case 213 is integrally formed with a support portion 213a protruding forward, the lower surface side of the attachment portion 225B of the reinforcing plate 225 is applied to the support portion 213a, and a bolt is applied to the screw portion of the support portion 213a from above. By tightening, the reinforcing plate 225 is detachably fixed to the support portion 213a. The inner end side of the horizontally long round pipe frame 226 is fixed to the lower surface side in the front and rear center part of the reinforcing plate 225, and the outer end side of the round pipe frame 226 is an inner part of the rear end part of the outer weed frame 214.

A large cover plate 352 is connected by a large number of connecting bolts 353. Accordingly, during large-scale maintenance or cleaning, the operator can enter the Glen tank 350 and perform work by removing the cover plate 352.
 前記穀粒搬出装置351は、グレンタンク350の底部に備えられたスクリューコンベヤ354で送り出される穀粒を上方側へ揚上搬送する縦送り筒355と、縦送り筒355の上端箇所から穀粒を横方向へ搬送して、吐出口356Cから外部へ取り出す横送り筒356とを備えて構成されている。前記縦送り筒355は、内部に穀粒搬送用の縦送りスクリュー355Aを備え、横送り筒356は内部に穀粒搬送用の横送りスクリュー356Aを備えている。 The grain carrying-out device 351 has a vertical feed cylinder 355 that lifts and conveys the grain sent out by a screw conveyor 354 provided at the bottom of the Glen tank 350, and a grain from an upper end portion of the vertical feed cylinder 355.

 縦送り筒355の上端側に連設される横送り筒356は、前記縦送り筒355の上端側と、前記横送り筒356の横側部に一体に取り付けてある支持体356Bとの間にわたって設けた油圧シリンダ358(起伏揺動操作用のアクチュエータの一例)によって、前記縦送り筒355の上端側における水平方向軸心x周りで起伏揺動自在に構成されている。 The horizontal feed cylinder 356 provided continuously with the upper end side of the vertical feed cylinder 355 extends between the upper end side of the vertical feed cylinder 355 and the support body 356B integrally attached to the lateral side portion of the horizontal feed cylinder 356. The provided hydraulic cylinder 358 (an example of an actuator for undulation swinging operation) is configured to be able to swing up and down around the horizontal axis x on the upper end side of the vertical feed cylinder 355.
 前記横送り筒356の穀粒搬送終端側における吐出口356Cには、その内面側に、図45に示すような感圧センサ359が付設されている。この感圧センサ359は、吐出口356C内で穀粒の詰まりが生じた場合にその圧力を検出するためのものであり、この感圧センサ359による検出信号は、図外の制御装置によって判別され、必要に応じてエンジン停止、または警報などの処理が行われる。 45. A pressure-sensitive sensor 359 as shown in FIG. 45 is attached to the inner surface of the discharge port 356C on the grain conveyance terminal side of the lateral feed tube 356. The pressure sensor 359 is used to detect the pressure when the grain clogs in the discharge port 356C. The detection signal from the pressure sensor 359 is discriminated by a control device (not shown). If necessary, processing such as engine stop or alarm is performed.
〔ガード部材の構成〕
 図41~図44に示すように、縦送り筒355の上部近くにおける外周面側には、起伏揺動操作用の前記油圧シリンダ358への圧油給排用の油圧ホース358a、及び各種センサ類などの電装品に対する配線用の電線ハーネス358bなどが、縦送り筒355の外周面から大きく離れた状態で縦送り筒355や横送り筒とともに旋回する状態を避けられるようにガード部材306を設けてある。上記の油圧ホース358aが、起伏揺動操作用のアクチュエータである油圧シリンダ358に接続された線材である。
[Configuration of guard member]
As shown in FIGS. 41 to 44, on the outer peripheral surface near the upper part of the vertical feed cylinder 355, a hydraulic hose 358a for supplying and discharging pressure oil to the hydraulic cylinder 358 for undulation swing operation, and various sensors A guard member 306 is provided so that the wire harness 358b for wiring with respect to the electrical components such as the above can be prevented from turning together with the vertical feed cylinder 355 or the horizontal feed cylinder in a state of being largely separated from the outer peripheral surface of the vertical feed cylinder 355. is there. The hydraulic hose 358a is a wire connected to a hydraulic cylinder 358 that is an actuator for undulation swing operation.
 前記ガード部材306は、縦送り筒355の外周面に沿った部分円弧状の丸棒材の両端側を屈曲させて縦送り筒355の上端側のフランジ部分355Cの下側に、取付ボルト361を介して着脱可能に取り付けてあり、前記フランジ部分355Cの外周縁との間に、前記油圧ホース358a及び電線ハーネス358bなどの線材の外径に比べて、縦送り筒355の径方向、及び周方向で十分に寸法上の余裕をもって挿入することのできる空間360を形成している。
 上記ガード部材306は、その両端側に取付板362を備え、この取付板362を前記フランジ部分355Cの下側に当てつけた状態で前記取付ボルト361で固定してある。
 このガード部材306によって前記フランジ部分355Cの外周縁との間に形成される空間360の前記縦送り筒355の周方向での範囲は、横送り筒356の旋回移動可能な角度範囲と同程度の角度範囲に設定されている。
The guard member 306 bends both ends of a partially arc-shaped round bar along the outer peripheral surface of the vertical feed cylinder 355 and attaches a mounting bolt 361 to the lower side of the flange portion 355C on the upper end side of the vertical feed cylinder 355. Between the outer peripheral edge of the flange portion 355C and the outer diameter of the wire such as the hydraulic hose 358a and the electric wire harness 358b, and the radial direction and the circumferential direction of the vertical feed cylinder 355. Thus, a space 360 that can be inserted with a sufficient dimensional margin is formed.
The guard member 306 is provided with mounting plates 362 on both ends thereof, and is fixed with the mounting bolts 361 in a state where the mounting plate 362 is applied to the lower side of the flange portion 355C.
The range in the circumferential direction of the vertical feed cylinder 355 of the space 360 formed between the guard member 306 and the outer peripheral edge of the flange portion 355C is approximately the same as the angular range in which the lateral feed cylinder 356 can turn. The angle range is set.
 上記のようにガード部材306によって、形成される空間360に前記油圧ホース358a及び電源ハーネス358bが挿通されていることで、横送り筒356が前記縦軸心y周りで旋回すると、油圧ホース358a及び電源ハーネス358bは横送り筒356の旋回方向と同方向に移動しようとする。このとき、前記ガード部材306も同方向に移動するので、ガード部材306と前記油圧ホース358a及び電源ハーネス358bとがそれほど大きく相対移動するわけではないが、前記油圧ホース358a及び電源ハーネス358bの機体固定部側の端部は位置固定状態であるため、ある程度の相対移動を生じることになる。つまり、横送り筒356の旋回方向が油圧ホース358a及び電源ハーネス358bの位置固定箇所から遠ざかる方向であれば引っ張られ、逆に近づく方向であれば押し戻されて、ガード部材306の空間360内を周方向に移動する。
 したがって、横送り筒356の旋回揺動がその旋回許容範囲の全体にわたって支障なく行えるように、前記油圧ホース358a及び電源ハーネス358bの長さをある程度余裕をもって設定しておいても、その油圧ホース358a及び電源ハーネス358bが縦送り筒355の外周面から離れる方向への移動が前記ガード部材306によって規制されることになる。
When the hydraulic hose 358a and the power supply harness 358b are inserted into the space 360 formed by the guard member 306 as described above, when the lateral feed cylinder 356 turns around the vertical axis y, the hydraulic hose 358a and The power harness 358b tends to move in the same direction as the turning direction of the lateral feed cylinder 356. At this time, since the guard member 306 also moves in the same direction, the guard member 306 and the hydraulic hose 358a and the power harness 358b do not move so much relative to each other, but the body of the hydraulic hose 358a and the power harness 358b is fixed. Since the end on the part side is in a fixed position, a certain amount of relative movement occurs. That is, if the turning direction of the lateral feed cylinder 356 is away from the position fixing position of the hydraulic hose 358a and the power harness 358b, it is pulled, and if it is in the opposite direction, it is pushed back and goes around the space 360 of the guard member 306. Move in the direction.
Therefore, even if the lengths of the hydraulic hose 358a and the power harness 358b are set with a certain margin so that the swinging movement of the lateral feed cylinder 356 can be performed without any trouble over the entire allowable swing range, the hydraulic hose 358a is provided. The movement of the power harness 358b in the direction away from the outer peripheral surface of the vertical feed cylinder 355 is restricted by the guard member 306.
 そして、横送り筒356が前記水平方向軸心x周りで起伏揺動する際には、前記油圧ホース358a及び電源ハーネス358bは、前記水平方向軸心xの半径方向で屈曲度合いを変化させるように動こうとするが、その動きが前記ガード部材306の存在によって制限されるので、油圧ホース358a及び電源ハーネス358bは、ガード部材306に対して、上下方向である程度相対移動する状態となり、やはり縦送り筒355の外周面から離れる方向への移動を規制されることになる。 When the lateral feed cylinder 356 undulates and swings around the horizontal axis x, the hydraulic hose 358a and the power harness 358b change the degree of bending in the radial direction of the horizontal axis x. The movement is limited by the presence of the guard member 306, so the hydraulic hose 358a and the power harness 358b are relatively moved relative to the guard member 306 in the vertical direction. Movement in a direction away from the outer peripheral surface of the tube 355 is restricted.
〔線材支持体〕
 前記油圧ホース358a及び電源ハーネス358bは、前記ガード部材306のみによって前記横送り筒356の旋回や起伏に伴う動きの規制が行われるだけではなく、線材支持体363によっても規制される。
 つまり、図41及び図43に示すように、一端側に油圧ホース358a及び電源ハーネス358bを囲繞する状態で支持する支持部分363aを備え、他端側に機体固定部側への取付部分363bを備えた線材支持体363を、前記ガード部材306よりも下方側に離れた位置に設けてある。
 この線材支持体363は、その支持部分363aに、図43及び図44に示すように、ガード部材306に設けられた空間360よりも旋回方向での許容角度範囲が少なく設定された空間364を備えている。
[Wire support]
The hydraulic hose 358a and the power harness 358b are not only restricted by the guard member 306 but also by the wire support 363, as well as by the movement of the transverse feed tube 356 that is caused by turning and undulation.
That is, as shown in FIGS. 41 and 43, a support portion 363a that supports the hydraulic hose 358a and the power supply harness 358b in a state of surrounding the hydraulic hose 358a is provided on one end side, and an attachment portion 363b on the airframe fixing portion side is provided on the other end side. A wire support 363 is provided at a position separated from the guard member 306 on the lower side.
As shown in FIGS. 43 and 44, the wire support 363 includes a space 364 in which the allowable angle range in the turning direction is set smaller than the space 360 provided in the guard member 306 in the support portion 363 a. ing.
 したがって、前記ガード部材306よりは少ない角度範囲で油圧ホース358a及び電源ハーネス358bの相対移動を許しながら、油圧ホース358a及び電源ハーネス358bの前記縦送り筒355の外周面からの離反度合いを少なくするように制限している。 Therefore, the hydraulic hose 358a and the power harness 358b are allowed to move relative to each other in an angle range smaller than that of the guard member 306, and the degree of separation of the hydraulic hose 358a and the power harness 358b from the outer peripheral surface of the vertical feed cylinder 355 is reduced. Restricted to
〔旋回高さ規制体〕
 図41,図42及び図46に示すように、前記グレンタンク350の天井部には、穀粒貯留装置305の横送り筒356の旋回角度範囲内において、その横送り筒356の旋回高さを規制するための旋回高さ規制体350cを設けてある。
(Swivel height regulating body)
As shown in FIGS. 41, 42, and 46, the ceiling of the Glen tank 350 has a swiveling height of the transverse feed cylinder 356 within the turning angle range of the transverse feed cylinder 356 of the grain storage device 305. A turning height restricting body 350c for restricting is provided.
 前記検出高さ規制体350cは、前記穀粒貯留装置305の横送り筒356が自走機体の上方を移動するに伴って、水平よりも下向き姿勢にある横送り筒356を上方側へ持ち上げ案内するように機能させるためのものであり、後述する上下向き軸心y回りで旋回する横送り筒356が、自走機体上を移動する際に、前記水平方向軸心x回りで上下揺動して、比較的機体上の高さが高い搭乗運転部308を交わして、機体上の格納用支持台312に載置させるようにするためのものである。
 この検出高さ規制体350cによる案内作用は、横送り筒356の前記上下向き軸心y回りの回動範囲で、前記格納用支持台312が存在する位置から、搭乗運転部308が存在する側の機体横端部との間で機能するものであり、これ以外の範囲では、検出高さ規制体350cによる案内作用は生じない。
The detection height regulating body 350c guides the horizontal feed cylinder 356 in a downward posture from the horizontal as the horizontal feed cylinder 356 of the grain storage device 305 moves above the self-propelled machine body. When the transverse feed cylinder 356 that turns around the vertical axis y, which will be described later, moves on the self-propelled machine body, it swings up and down around the horizontal axis x. Thus, the boarding operation unit 308 having a relatively high height is exchanged and placed on the storage support 312 on the aircraft.
The guiding action by the detection height restricting body 350c is the side where the boarding operation unit 308 exists from the position where the storage support base 312 exists in the rotation range of the transverse feed tube 356 around the vertical axis y. This function functions between the horizontal end of the machine body, and the guide action by the detection height restricting body 350c does not occur outside this range.
〔第4実施形態の別形態1〕
 上記実施形態においては、ガード部材306によって形成される空間360の前記縦送り筒355の周方向での範囲は、横送り筒356の旋回移動可能な角度範囲と同程度の角度範囲に設定したものであるが、この角度範囲はこのような範囲に設定されるだけのものに限らず、任意に設定することができる。すなわち、横送り筒の旋回揺動範囲にもよるが、前記油圧ホース358a及び電源ハーネス358bに過大な引っ張り作用や曲げ作用が作用することを避けられる程度に、ガード部材306と油圧ホース358a及び電源ハーネス358bなどの線材との相対移動が許容される程度であればよい。
[Another embodiment 1 of the fourth embodiment]
In the above-described embodiment, the range of the space 360 formed by the guard member 306 in the circumferential direction of the vertical feed cylinder 355 is set to an angle range comparable to the angular range in which the lateral feed cylinder 356 can move. However, the angle range is not limited to such a range and can be arbitrarily set. That is, the guard member 306, the hydraulic hose 358a, and the power source can be avoided to the extent that an excessive pulling action or bending action is applied to the hydraulic hose 358a and the power supply harness 358b, depending on the swivel swing range of the lateral feed cylinder. It is only necessary to allow relative movement with a wire such as the harness 358b.

Of course, the combine is not limited to the self-removing combine, and may be applied to a normal combine.
 以上説明した通り、この実施形態は、グレンタンクの下端側から取り出された穀粒を上方側へ揚送する縦送り筒と、その縦送り筒の上下軸心周りで旋回移動自在に、かつ、縦送り筒の上端近くの水平軸心周りで起伏揺動自在に構成された横送り筒とからなる穀粒搬出装置を設けたコンバインにおいて、

 この構成は、以下の点で有利である。
As described above, this embodiment is a vertical feed cylinder that feeds the grain taken out from the lower end side of the Glen tank upward, and is capable of swiveling around the vertical axis of the vertical feed cylinder, and In a combine provided with a grain carry-out device composed of a horizontal feed cylinder configured to be swingable up and down around a horizontal axis near the upper end of the vertical feed cylinder,
An actuator for swinging the horizontal feed cylinder between the vertical feed cylinder and the horizontal feed cylinder is provided, and the actuator moves around the vertical axis together with the horizontal feed cylinder that pivots around the vertical axis of the vertical feed cylinder. A guard member is provided outside the outer peripheral surface of the vertical feed cylinder so as to surround the outer side of the wire connected to the actuator, and the wire is longitudinally moved to the guard member as the lateral feed cylinder is swung. A space for allowing relative movement in the circumferential direction of the feed tube is provided.
This configuration is advantageous in the following points.
 上記コンバインでは、縦送り筒の上端側で上下軸心周りで旋回移動自在、かつ起伏揺動自在な横送り筒を縦送り筒に対して起伏揺動させるために設けられたアクチュエータを備え、そのアクチュエータに対して接続された線材を保護するためのガード部材を設けるにあたり、前記ガード部材が、縦送り筒の上下軸心周りで旋回移動する横送り筒とともに前記上下軸心まわりで移動するように縦送り筒の外周面の外側に設け、かつ、そのガード部材に横送り筒の旋回移動にともなって前記線材が縦送り筒の周方向で相対移動することを許容する空間を設けてある。
 つまり、ガード部材を用いて、アクチュエータに対して接続された線材が縦送り筒の外周部付近に位置する状態を維持するようにしながら、横送り筒の旋回時には、前記ガード部材が線材に対して相対移動しながら横送り筒と同方向に移動するので、線材を無理に引っ張ったり必要以上に緩み側へ操作することがない。
 また、横送り筒の起伏揺動時には、前記ガード部材によって縦送り筒から離れる側への線材の移動を制限することができ、しかも、その制限が、縦送り筒に対する横送り筒の位置が前記空間に相当する旋回方向の広範囲で行われるので、他物への線材の接触を回避し易くなる。
 したがって、横送り筒とともに旋回移動するようにガード部材を設け、かつ、そのガード部材に線材が周方向で相対移動することを許容する空間を形成するという、構造的にはきわめて簡単な構成によって、アクチュエータに接続された線材の保護を行うことができる利点がある。
The above combine includes an actuator provided for swinging the vertical feed cylinder up and down with respect to the vertical feed cylinder. In providing a guard member for protecting the wire connected to the actuator, the guard member moves around the vertical axis together with the lateral feed cylinder that pivots around the vertical axis of the vertical feed cylinder. A space is provided outside the outer peripheral surface of the vertical feed cylinder, and the guard member is provided with a space that allows the wire rod to relatively move in the circumferential direction of the vertical feed cylinder as the horizontal feed cylinder turns.
In other words, the guard member is used to maintain the state where the wire connected to the actuator is located near the outer peripheral portion of the vertical feed cylinder, while the lateral feed cylinder is turning, the guard member is in contact with the wire. Since it moves in the same direction as the lateral feed cylinder while relatively moving, there is no need to forcibly pull the wire or operate it more loosely than necessary.
Further, when the horizontal feed cylinder is swung up and down, the guard member can restrict the movement of the wire to the side away from the vertical feed cylinder, and the restriction is that the position of the horizontal feed cylinder relative to the vertical feed cylinder is Since it is performed in a wide range of the turning direction corresponding to the space, it is easy to avoid contact of the wire with other objects.
Therefore, a guard member is provided so as to pivot with the lateral feed cylinder, and a space that allows relative movement of the wire in the circumferential direction is formed in the guard member. There is an advantage that the wire connected to the actuator can be protected.
 さらに好適には、ガード部材に設けられる空間は、横送り筒の旋回移動可能な角度範囲と同程度の角度範囲にわたって形成されていることを特徴とする。
 この構成によれば、ガード部材に設けられる空間が、横送り筒の旋回移動可能な角度範囲と同程度の角度範囲にわたって形成されているから、縦送り筒と横送り筒との相対的な位置関係が、横送り筒の旋回移動可能な角度範囲のどの位置であっても、前記ガード部材によって縦送り筒から離れる側への線材の移動を制限し、他物への線材の接触を回避し易くなる利点がある。
More preferably, the space provided in the guard member is formed over an angular range that is about the same as the angular range in which the lateral feed cylinder can turn.
According to this configuration, since the space provided in the guard member is formed over an angular range that is approximately the same as the angular range in which the horizontal feed cylinder can be swung, the relative position between the vertical feed cylinder and the horizontal feed cylinder. Regardless of the position within the angular range in which the lateral feed cylinder can pivot, the guard member restricts the movement of the wire to the side away from the vertical feed cylinder and avoids contact of the wire with other objects. There is an advantage which becomes easy.
 また、ガード部材よりも下方側に離れた位置で、ガード部材に設けられた空間よりも旋回方向での許容角度範囲が少ない線材支持体を、機体固定部側に設けてあることも好適である。
 この構成によれば、ガード部材よりも下方側に離れた位置にも線材支持体を設けてあるので、アクチュエータに接続された線材の縦送り筒の周辺からの離間をより一層確実に抑制することができる。
 しかも、ガード部材よりも下方側に離れた位置に設けられる前記線材支持体は、ガード部材に設けられた空間よりも旋回方向での許容角度範囲が少ない状態で支持するものであるから、前記線材の支持を、前記ガード部材側での支持と、機体固定部側での支持との中間的な支持状態で行うことができる。
 したがって、アクチュエータに接続された線材の支持を、横送り筒の動きによる影響が少ない機体固定部側から横送り筒の動きによる影響が大きい横送り筒側にわたって、次第に融通度合いが大きくなるような支持形態で支持し、より一層、縦送り筒外周からの線材の離反度合いの少ない状態で支持することができる利点がある。
In addition, it is also preferable that a wire support having a smaller allowable angle range in the turning direction than the space provided in the guard member is provided on the airframe fixing portion side at a position away from the guard member. .
According to this configuration, since the wire support is also provided at a position away from the guard member, the separation of the wire connected to the actuator from the periphery of the vertical feed cylinder can be more reliably suppressed. Can do.
And since the said wire support body provided in the position away from the guard member at the lower side supports a state where the allowable angle range in the turning direction is smaller than the space provided in the guard member, the wire rod This support can be performed in an intermediate support state between the support on the guard member side and the support on the airframe fixing portion side.
Therefore, the support of the wire connected to the actuator is supported so that the degree of flexibility gradually increases from the side of the machine body fixing part where the influence of the movement of the lateral feed cylinder is small to the side of the lateral feed cylinder where the influence of the movement of the lateral feed cylinder is large. There is an advantage that it can be supported in a form and can be supported in a state where the degree of separation of the wire from the outer periphery of the vertical feed cylinder is small.
