As the harvesting and transporting structure of the harvesting and harvesting machine as described above, a rotary body (auxiliary transport apparatus) provided with a plurality of projecting portions for scraping and transporting in the scraping and transporting apparatus, and a rotational center side of the rotating body are covered. Some of them are equipped with a cover that prevents the wrapping of the cereals around the rotating body. In the cutting and transporting structure having such a configuration, when the scraping and transporting device is viewed from the direction perpendicular to the plane of the scraping and transporting device, the cover is positioned on the front side of the vehicle body with respect to the tip of the cutting blade of the cutting device. As described above, a scraping and conveying apparatus is configured (see, for example, Patent Document 1).
JP 2007-289027 A

ところで、掻込搬送装置の回動体には、掻き込み搬送用の複数の突出部を一体形成したゴム製の掻込ベルトを備えるものを採用することが一般的である。そのため、回動体が刈り取り前の作物の穀稈に作用した場合には、掻込ベルトの突出部が、刈り取り前の穀稈の強度に負けて変形することにより、その穀稈が刈り取られるまでの間、その穀稈を回動体によって穀稈通過部に向けて掻き込み搬送することができなくなる。   By the way, it is common to employ | adopt what is provided with the rubber | gum rake belt which integrally formed the several protrusion part for rake conveyance as the rotation body of an rake conveyance apparatus. Therefore, when the rotating body acts on the crop culm before cutting, the protrusion of the scraping belt deforms losing the strength of the culm before cutting, until the culm is harvested. During that time, the cereals cannot be scraped and conveyed by the rotating body toward the cereal passing part.

このような場合に、掻込搬送装置のカバーが、刈取装置の刈刃の先端よりも車体前方側に位置するように構成していると、そのカバーが、車体の走行に伴って、刈り取り前の穀稈に接当して、その穀稈を車体の進行方向に向けて押し曲げるようになる。   In such a case, if the cover of the take-up conveyance device is configured to be positioned on the front side of the vehicle body relative to the tip of the cutting blade of the reaping device, the cover is not cut before the vehicle is traveling. The cedar is touched and bent toward the advancing direction of the vehicle body.

そして、このように押し曲げられた作物の穀稈が、刈取装置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、車体の進行方向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、掻込搬送装置から離れる車体の進行方向に飛び出して、掻込搬送装置の搬送領域から外れることがある。   Then, when the culm of the crop pushed and bent in this way reaches the cutting position of the cutting device and is cut, it tries to return to the straight state from the pushed and bent state toward the traveling direction of the vehicle body with the cutting. Due to the restoring action to be performed, the vehicle may jump out in the traveling direction of the vehicle body away from the picking-up transport device and deviate from the transport region of the picking-up transport device.

このような現象が通常の刈り取り作業時に発生しても、掻込搬送装置の搬送領域から外れた穀稈は、車体の走行とともに掻込搬送装置の搬送領域に向けて次々と導入される後続の穀稈により、掻込搬送装置の搬送領域内に押し戻されるようになることから、掻込搬送装置によって穀稈通過部に向けて掻き込み搬送することができる。   Even if such a phenomenon occurs during a normal mowing operation, the cereals that have deviated from the transport region of the scraping transport device are successively introduced toward the transport region of the scraping transport device as the vehicle travels. Since the culms are pushed back into the transport area of the scraping and transporting device, they can be scraped and transported toward the culm passing section by the scraping and transporting device.

しかしながら、上記の現象が、刈取搬送部による刈り取り搬送を中断する畦際旋回などの直前や、刈取搬送部による穀稈の刈り取り搬送量が少ない圃場の隅部での刈り取り作業時などにおいて発生すると、掻込搬送装置の搬送領域から外れた穀稈を搬送領域内に押し戻すことができなくなり、結果、搬送領域から外れたままこぼれ落ちる穀稈が多発することになる。   However, when the above-mentioned phenomenon occurs immediately before the turning turning to interrupt the cutting and conveying by the cutting and conveying unit, or at the time of the cutting operation at the corner of the farm field where the amount of cutting and conveying of the cereal by the cutting and conveying unit is small, The cereals that have fallen out of the transfer area of the scraping transfer device can no longer be pushed back into the transfer area, resulting in frequent occurrence of cereals that fall out of the transfer area.

本発明の目的は、掻込搬送装置のカバーが刈り取り前の穀稈に接当することに起因して、掻込搬送装置の搬送領域からこぼれ落ちる穀稈が多発することを防止することにある。   An object of the present invention is to prevent frequent occurrence of cereals spilling from the conveying region of the rake conveying device due to the cover of the rake conveying device coming into contact with the culm before cutting. .

Then, the culm of up to two crops C introduced between the right weed member 21 </ b> B and the middle weed member 21 </ b> C is raked 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、左側の引起装置22Aは、刈取搬送部3の入力軸39から、伝動軸41、中継軸43、動力分配軸45、および左伝動軸47、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。   That is, the left pulling device 22A is operated by the power transmitted from the input shaft 39 of the cutting and conveying unit 3 through the transmission shaft 41, the relay shaft 43, the power distribution shaft 45, the left transmission shaft 47, 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39から、伝動軸41、中継軸43、動力分配軸45、右伝動軸49、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 39 of the cutting and conveying unit 3 through the transmission shaft 41, the relay shaft 43, the power distribution shaft 45, the right transmission shaft 49, 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.

さらに、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。   Further, the left and right pulling devices 22A and 22B are supplied with a plurality of pulling claws 59A and 59B, and the grains C of the crop C introduced between the corresponding ones of the three weeding members 21A to 21C. 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.

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、よって、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. Therefore, the centroid position of the cutting and conveying unit 3 can be lowered as compared with the case of adopting an arch structure in which an axial transmission mechanism is installed over the upper parts of the left and right pulling devices 22A and 22B. This can improve the stability of the vehicle body.

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、その穀稈の搬送姿勢に乱れが生じ、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り、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ることから、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 matter such as mud and weeds easily accumulates on the transmission system case. Due to this disturbance, the alignment of the tip side when the supply and transport device 25 transports the cereal toward the threshing device 4 becomes worse, and unhandled residue is likely to occur during the threshing process in the threshing device 4. As a result, the grain recovery efficiency is likely to decrease.

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.

Covers 77A and 77B for preventing the wrapping of the cereals with respect to the The left and right packers 72A and 72B are integrally formed with a plurality of projecting portions 72a and 72b for scraping and transporting on the outer periphery thereof.

左側の掻込搬送装置24Aは、その掻込搬送機構71Aの駆動プーリ75Aとパッカ72Aとを、刈取搬送部3の左右中央側に位置するように、支持部材37に備えた支軸78に回転可能に支持させてある。また、その掻込搬送機構71Aの従動プーリ76Aを、刈取搬送部3の左端部で駆動プーリ75Aよりも前側に位置するように、左支持部材66Aの左端部に一体装備した左補助部材79Aに支持させてある。   The left picking and conveying device 24A rotates the driving pulley 75A and the packer 72A of the picking and conveying mechanism 71A to the support shaft 78 provided in the support member 37 so as to be positioned on the left and right center side of the cutting and conveying unit 3. It is supported as possible. Further, the left auxiliary member 79A integrally provided at the left end portion of the left support member 66A is arranged such that the driven pulley 76A of the scraping transfer mechanism 71A is positioned at the front end of the drive pulley 75A at the left end portion of the cutting transfer portion 3.

その結果、左右の掻込搬送装置24A,24Bにより、刈取装置23により刈り取った穀稈を掻き込み搬送する際には、その穀稈の株元側を刈取装置23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。   As a result, when the left and right scraping and transporting devices 24A and 24B scrape and transport the cereals harvested by the reaping device 23, it is possible to make the stocker side of the cereals less likely to come into contact with the reaping device 23. Thus, due to the contact posture of the cereal being disturbed by the contact, the alignment of the tip side when conveying the cereal toward the threshing device 4 by the supply and transport device 25 becomes worse, and the threshing device 4 In the threshing process, it is possible to avoid a decrease in the grain recovery rate such that unhandled items are easily generated.

図4〜9および図13に示すように、左側の掻込搬送装置24Aは、その掻込搬送機構71Aの駆動プーリ75Aとパッカ72Aとが一体回転するように、その駆動プーリ75Aとパッカ72Aとを連結してある。右側の掻込搬送装置24Bは、その掻込搬送機構71Bの駆動プーリ75Bとパッカ72Bとが筒軸80と一体回転するように、その駆動プーリ75Bとパッカ72Bとを筒軸80に連結してある。筒軸80は、ギア式の減速機構81を介して右伝動軸49と連動する。左側のパッカ72Aは右側のパッカ72Bと噛み合い連動する。 As shown in FIGS. 4 to 9 and FIG. 13, the left-side scraping / conveying device 24 </ b> A includes the driving pulley 75 </ b> A and the packer 72 </ b> A so that the driving pulley 75 </ b> A and the packer 72 </ b> A of the scraping / conveying mechanism 71 </ b> A rotate integrally. Are connected. The right-hand drive mechanism 24B connects the drive pulley 75B and the packer 72B to the cylinder shaft 80 so that the drive pulley 75B and the packer 72B of the drive mechanism 71B rotate integrally with the cylinder shaft 80. is there. The cylindrical shaft 80 is interlocked with the right transmission shaft 49 via a gear type reduction mechanism 81. The left packer 72A meshes with and interlocks with the right packer 72B.

つまり、左右の掻込搬送装置24A,24Bは、右伝動軸49から減速機構81および筒軸80を介して伝達される動力により作動し、この作動により、刈取装置23により刈り取った穀稈を、左右のパッカ72A,72Bの噛合部である穀稈通過部27に向けて掻き込み搬送し、穀稈通過部27から穀稈受け渡し位置に向けて掻き出し搬送するように構成してある。   That is, the left and right scraping and conveying devices 24A and 24B are operated by power transmitted from the right transmission shaft 49 via the speed reduction mechanism 81 and the cylinder shaft 80, and by this operation, the cereals harvested by the reaping device 23 are It is configured such that it is scraped and transported toward the cereal passing part 27 which is the meshing part of the left and right packers 72A and 72B, and is scraped and transported from the stalk passing part 27 toward the cereal passing position.

図1、図2および図4に示すように、供給搬送装置25は、左右の掻込搬送装置24A,24Bにより穀稈受け渡し位置に掻き出し搬送された穀稈の株元側を挟持して搬送する挟持搬送機構82と、その穀稈の穂先側を係止して搬送する係止搬送機構83とを上下に配置して構成してある。挟持搬送機構82および係止搬送機構83は、それらの入力軸として機能する伝動軸84が一対のベベルギア85を介して刈取搬送部3の入力軸39と連動することにより、穀稈通過部27の穀稈を脱穀用の横倒れ姿勢に姿勢変更しながら脱穀装置4に向けて供給搬送するように構成してある。   As shown in FIGS. 1, 2, and 4, the supply and transport device 25 sandwiches and transports the stock side of the cereal that has been scraped and transported to the cereal delivery position by the left and right scraping transport devices 24 </ b> A and 24 </ b> B. The sandwiching and transporting mechanism 82 and the locking and transporting mechanism 83 that locks and transports the tip side of the grain pod are arranged vertically. The holding and conveying mechanism 82 and the locking and conveying mechanism 83 are configured so that the transmission shaft 84 functioning as an input shaft thereof is linked to the input shaft 39 of the harvesting and conveying unit 3 via a pair of bevel gears 85, thereby It is configured to supply and transport the cereals toward the threshing device 4 while changing the posture to the sideways posture for threshing.

図8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 and 13, in the cutting and conveying unit 3, the middle weed member 21 </ b> C is positioned between 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 width of the culm passing unit 27. It is arranged to do.

この配置により、左右の掻込搬送装置24A,24Bにより穀稈を穀稈通過部27に搬送する際に、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 left and right scraping and conveying devices 24A and 24B convey the cereal to the cereal passage section 27, the cereal is prevented from moving across the middle weed member 21C. it can. 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により穀稈通過部27に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 to the cereal passing part 27 by the left and right scavenging and 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 in the posture of the grain straws caused by the contact.

図2、図3および図14に示すように、反搭乗運転部側に位置する左側のクローラ13Aは、その車体横外方側の端部となる左端部13Aaが、刈取搬送部3の最反搭乗運転部側に位置する左分草部材21Aの分草始端21Aaと左右方向で一致するように配置してある。また、搭乗運転部側に位置する右側のクローラ13Bは、その車体横外方側の端部となる右端部13Baが、刈取搬送部3の最搭乗運転部側に位置する右分草部材21Bの分草始端21Baから車体の右外方側に少しだけ食み出すように配置してある。   As shown in FIGS. 2, 3, and 14, the left crawler 13 </ b> A located on the anti-boarding operation unit side has the left end portion 13 </ b> Aa that is the end portion on the laterally outer side of the vehicle body being the farthest farthest of the cutting conveyance unit 3. It arrange | positions so that it may correspond with the weeding start end 21Aa of the left weeding member 21A located in the boarding operation part side in the left-right direction. Further, the right crawler 13B located on the boarding operation part side has a right end part 13Ba that is an end part on the laterally outer side of the vehicle body of the right weeding member 21B located on the most boarding operation part side of the cutting and conveying part 3. It arrange | positions so that it may protrude slightly from the weeding start end 21Ba to the right outer side of a vehicle body.

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、車体の左側に未刈りの作物Cxが存在する回り刈りや車体の左右両側に未刈りの作物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で車体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で車体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 crawler 13 </ b> A causes the left outer side of the vehicle body to move around when the unmoved crop Cx is present on the left side of the vehicle body, or when the left and right sides of the vehicle body are partially divided such that the uncut crops Cx and Cy are present. It is possible to prevent inconveniences such as stepping on an uncut crop Cx located in the vicinity, or mud approaching an uncut crop Cx located near the left outer side of the vehicle body with the left crawler 13A, It is possible to avoid a decrease in work efficiency due to the trampling and mud gathering.

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、車体の左右両側に未刈りの作物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の作業幅内で最搭乗運転部側に位置する作物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すれば、右側のクローラ13Bで車体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 right crawler 13B has its right end portion 13Ba substantially coincided with the weed start end 21Ba of the right weed member 21B in the left-right direction, so that uncut crops Cx, Cy exist on the left and right sides of the vehicle body. During work traveling such as middle splitting, the weed start end 21Ba of the right weed member 21B is located within the work width of the cutting and conveying unit 3 on the side of the most boarding operation unit, and outside the work width adjacent to this crop Cb. If it passes through the side of the crop Cb within the work width with the other crop Cy, the inconvenience of stepping on the uncut crop Cy located near the right outside of the vehicle body with the right crawler 13B Therefore, it is possible to avoid a decrease in work efficiency due to the stepping.

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から車体の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 weeding start end 21Ba to the right outer side of the vehicle body is determined by the right crawler 13B by stepping on the uncut crop Cy near the right outer side of the vehicle body. Can be set to various lengths such as Lz = 1/3 * Sc and Lz = 1/4 * Sc, for example, in relation to 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 with respect to the uncut crop Cy near the right outer side of the vehicle body by the right crawler 13B can be suppressed, and the reduction in work efficiency due to the mud gathering is 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.

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 outer side of the body of the left weeding member 21A within a range in which it is possible to prevent the neighboring uncutting crop Cx from being stepped on and to suppress mud approach to the uncut crop Cx. You may arrange | position so that it may be located.

図14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、搭乗運転部2の前下方に位置する右分草部材21Bの前端側が、刈取搬送部3の作業幅内で最搭乗運転部側に位置する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に対して右分草部材21Bを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の作業幅内で最反搭乗運転部側に位置する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. 14, the three weeding members 21 </ b> A to 21 </ b> C have the front end side of the right weeding member 21 </ b> B located at the front lower side of the boarding operation unit 2 at the time of the operation of harvesting the four crops C. Between the rightmost crop Cb in the work width located on the side of the most boarding operation part within the work width of the section 3 and the crop Cy or crop cut mark Cz outside the right work width adjacent to the crop Cb, When the right weed member 21B is aligned with the crop C so as to pass close to the crop Cb within the work width, the middle weed member 21C is located at the left and right center sides within the work width to be acted on. The left weed member 21A passes through an intermediate position or a substantially intermediate position between the two crops Cc and Cd positioned at the position of the cropping transport unit 3 and is located on the farthest boarding operation unit side. Crop C on the left and crop C outside the working width on the left side adjacent to this crop Ca Or between the cutting marks Cz crops, it is arranged so as to pass through the position close to the crop Ca in the working width than their intermediate position.

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の前端側を、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 front end side of the right weeding member 21 </ b> B with high visibility from the boarding operation unit 2 is positioned at the rightmost position within the work width by being positioned in front of the boarding operation unit 2. 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 aligning them so as to pass near the right side of the crop Cb to be Without visually recognizing, the crop C can be passed through an appropriate position away from the planting position, and pushing and stepping of the crop C by the weeding members 21A and 21C can be avoided.

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。   Thereby, even if the lodging of the crop C is intense, each weeding member 21A-21B can be easily and reliably aligned with the appropriate position with respect to the crop C, and each weeding member 21A-21B and 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って、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って、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。   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 of the left and right scratches is removed. It is possible to prevent a reduction in the conveying efficiency of the cereal straw by the embedded conveying devices 24A and 24B. Further, it is possible to prevent an unnecessary delay in the transportation of the cereals by either one of the left and right scraping and transporting devices 24A, 24B, and the supply and transportation due to the disturbance in the posture of the cereals caused by this delay. 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の前端側を、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。   Moreover, when the left weed member 21A passes near the left side of the leftmost crop Ca within the working width, the front end of the right weed member 21B is always in operation during harvesting of the four crops C. The side needs to be aligned so as to pass near the right lateral side of the crop Cb located at the rightmost position within the working 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〜21C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。   Thereby, at the time of the work traveling for harvesting the four crops C, the weeding members 21A to 21C can be surely passed through the appropriate positions described above with respect to the crop C. It is possible to improve the workability at the time of the work traveling for harvesting the crop C.

図15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、搭乗運転部2の前下方に位置する右分草部材21Bの前端側が、刈取搬送部3の作業幅内の最搭乗運転部側に位置する作業幅内右側の作物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に対して右分草部材21Bの前端側を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の作業幅内の最反搭乗運転部側に位置する作業幅内左側の作物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. 15, the three weeding members 21 </ b> A to 21 </ b> C are cut and transported by the front end side of the right weeding member 21 </ b> B located in front of the boarding operation unit 2 during the operation of harvesting the three crops C. Right with respect to the right crop harvest Cz so as to pass above the right crop Cb adjacent to the right crop Cb within the work width located on the most boarding operation part side within the work width of the section 3 When the front end side of the weeding member 21B is aligned, the middle weeding member 21C is on the right side between the two crops Cb and Cc located on the right side and the left and right center side within the working width to be acted on. The left weed member 21A passes through a position closer to the crop Cc on the left and right center side than the other crop Cb, and is located on the farthest boarding operation unit side within the work width of the cutting and transporting unit 3 as the action target. Crop Ca on the left side in the working width and the crop on the left side adjacent to this crop Ca Is arranged so as to pass through the intermediate position or substantially intermediate position between the width outside the crop Cx or crop cutting marks Cz.

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の前端側を、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。   In other words, during the three-row cutting operation, the front end side of the right weeding member 21B with high visibility from the boarding operation unit 2 is positioned above the right side cutting mark Cz by being positioned in front of and below the boarding operation unit 2. By positioning so as to pass, the left weed member 21A and the middle weed member 21C, which are less visible from the boarding operation unit 2 by moving away from the boarding operation unit 2, can be seen without cropping them. Therefore, it is possible to avoid pushing down or 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 be used to 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って、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。   Thereby, the conveyance efficiency at the time of carrying out the scraping conveyance of the 3 grains of cereals toward the cereal passing part 27 by the left and right rake conveying devices 24A, 24B can be improved. Further, it is possible to prevent an unnecessary delay in the transportation of the cereals by either one of the left and right scraping and transporting devices 24A, 24B, and the supply and transportation due to the disturbance in the posture of the cereals caused by this delay. 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、作業幅内の左側に位置する作物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 on the left side in the work width and the crop Cx or the crop cut mark Cz outside the left work width. During the operation of harvesting the three crops C, the left weeding 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 positioned.

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 weeding members 21A to 21C for satisfying the positional relationship between the three weeding members 21A to 21C and the crop C described above, the left-right distance Sa between the three weeding members 21A to 21C , 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2、図3、図7、図12および図13に示すように、前端側が搭乗運転部2の前下方に位置する右分草部材21Bを備えた右側の引起枠26Bにおいて、この引起枠26Bに備える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. 2, 3, 7, 12, and 13, in the right pulling frame 26 </ b> B that includes the right weed member 21 </ b> B whose front end is positioned in front of the boarding operation unit 2, the pulling frame 26 </ b> B is provided. The two-row pulling device 22 </ b> B provided for is configured such that the raising region Ab <b> 2 is located on the left side away from the boarding operation unit 2.

これにより、右側の引起枠26Bに、引き起こし領域Ab2が搭乗運転部側であ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。   Thus, the vehicle body from the boarding operation unit 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 unit 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.

図2、図3、図7、図12および図13に示すように、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。   As shown in FIG. 2, FIG. 3, FIG. 7, FIG. 12 and FIG. 13, the left and right pulling devices 22A and 22B have the left and right widths Wa and Wb of the raising regions Aa2 and Ab2 of a maximum It is formed wide to accommodate the cause. 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、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わせることができる。   Accordingly, when the left and right pulling devices 22A and 22B are in a four-row mowing operation that always causes two ridges each, the resistance when the cereals pass through the corresponding trigger areas Aa2 and Ab2 on the left and right is within an allowable range. This can be prevented. As a result, it is possible to smoothly and satisfactorily cause cereals to be caused by the left and right pulling devices 22A and 22B even during the four-row mowing 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わせることができる。   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条刈りと4条刈りとにかかわらず、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 3 and 4 cuttings, the left pulling device 22A, to which 2 threads are always fed, causes the left and right width Wa of the area Aa2 to cause a maximum of 2 threads. It may be configured to have a corresponding width, and the pulling claw 59A has a long length corresponding to the wide cause area Aa2.

ところで、左右の掻込搬送装置24A,24Bは、穀稈の株元側の上部を掻き込み搬送する回動体として、ゴム製の掻込ベルト74A,74Bを備えた掻込搬送機構71A,71Bを採用していることにより、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することにより、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。   By the way, the left and right scraping and transporting devices 24A and 24B have a scraping and transporting mechanism 71A and 71B provided with rubber scratching belts 74A and 74B as a rotating body that scrapes and transports the upper part of the cereal stock side. By adopting, when acting on the culm before cutting, the protrusions 74a, 74b of the scraping belts 74A, 74B are deformed by losing the strength of the culm before cutting, so that the grain Until the cocoon is cut off, the cedar is scraped and conveyed toward the cereal passage portion 27.

このような場合に、左右の掻込搬送装置24A,24Bを、それらに備えた穀稈巻き付き防止用のカバー77A,77Bが、刈取装置23の刈刃である可動刃68および固定刃69の先端よりも車体前方側に位置するように構成していると、そのカバーが、車体の走行に伴って、刈り取り前の穀稈に接当して、その穀稈を車体の進行方向に向けて押し曲げるようになる。   In such a case, the left and right scraping and conveying devices 24A and 24B are provided with the cover 77A and 77B for preventing the winding of the culm, and the tips of the movable blade 68 and the fixed blade 69 that are the cutting blades of the reaping device 23. If the cover is configured to be located on the front side of the vehicle body, the cover touches the culm before cutting and pushes the culm toward the traveling direction of the vehicle body as the vehicle travels. Bend.

そして、このように押し曲げられた作物Cの穀稈が、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、車体の進行方向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、左右の掻込搬送装置24A,24Bから離れる車体の進行方向に飛び出して、左右の掻込搬送装置24A,24Bの搬送領域から外れることがある。   Then, when the cereal of the crop C thus bent and bent reaches the cutting position of the cutting device 23 and is cut, the cutting and the cutting are performed in the straight direction from the state pushed and bent toward the traveling direction of the vehicle body. Due to the restoring action to return, the vehicle may jump out in the traveling direction of the vehicle body away from the left and right scraping and conveying devices 24A and 24B, and deviate from the conveying area of the left and right scraping and conveying devices 24A and 24B.

このような現象が通常の刈り取り作業時に発生しても、左右の掻込搬送装置24A,24Bの搬送領域から外れた穀稈は、車体の走行とともに左右の掻込搬送装置24A,24Bの搬送領域に向けて次々と導入される後続の穀稈により、左右の掻込搬送装置24A,24Bの搬送領域内に押し戻されるようになることから、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することができる。   Even if such a phenomenon occurs during a normal mowing operation, the cereals that have deviated from the conveyance area of the left and right scraping and conveying devices 24A and 24B are transported by the left and right scraping and conveying apparatuses 24A and 24B as the vehicle travels. Since the subsequent cereals introduced one after another are pushed back into the conveyance area of the left and right rake conveying devices 24A and 24B, the left and right rake conveying devices 24A and 24B cause the 27 can be scraped and conveyed.

しかしながら、上記の現象が、刈取搬送部3による刈り取り搬送を中断する畦際旋回などの直前や、刈取搬送部3による穀稈の刈り取り搬送量が少ない圃場の隅部での刈り取り作業時などにおいて発生すると、左右の掻込搬送装置24A,24Bの搬送領域から外れた穀稈を搬送領域内に押し戻すことができなくなり、結果、搬送領域から外れたままこぼれ落ちる穀稈が多数発生することになる。   However, the above-mentioned phenomenon occurs immediately before the turning turning to interrupt the cutting and conveying by the cutting and conveying unit 3 or at the time of the cutting operation at the corner of the farm field where the amount of the cutting and conveying of the cereal by the cutting and conveying unit 3 is small. As a result, the cereals that have been removed from the conveyance areas of the left and right scraping conveyance devices 24A and 24B cannot be pushed back into the conveyance area, and as a result, a large number of cereals that fall out from the conveyance area are generated.

そこで、図5〜7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を、それらの平面に対する垂直方向から各掻込搬送装置24A,24Bを見た場合に、それらのカバー77A,77Bが、刈取装置23の刈刃である可動刃68および固定刃69の先端よりも車体後方側に位置するように、好ましくは、可動刃68および固定刃69の車体前後方向での刈取作用範囲の中間部よりも車体後方側に位置するように構成してある。   Therefore, as shown in FIGS. 5 to 7, in this combine, when the left and right scratch conveying devices 24 </ b> A and 24 </ b> B are viewed from the vertical direction with respect to their planes, The cutting of the movable blade 68 and the fixed blade 69 in the longitudinal direction of the vehicle body is preferably performed so that 77A and 77B are located on the rear side of the vehicle body with respect to the distal ends of the movable blade 68 and the fixed blade 69 which are the cutting blades of the cutting device 23. It is configured to be located on the rear side of the vehicle body relative to the middle part of the operating range.

これにより、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た場合であっても、カバー77A,77Bが、車体の走行に伴って、刈り取り前の穀稈に接当して、その穀稈を車体の進行方向に向けて押し曲げるようになることを防止することができる。その結果、その押し曲げに起因して、押し曲げられた穀稈が、刈り取りとともに左右の掻込搬送装置24A,24Bの搬送領域から外れてこぼれ落ちることを防止することができる。   As a result, even if the protrusions 74a and 74b of the scraping belts 74A and 74B are deformed by losing the strength of the cereal before cutting, the covers 77A and 77B are not cut before the vehicle travels. It is possible to prevent the rice cake from being pushed and bent toward the traveling direction of the vehicle body. As a result, it is possible to prevent the pushed and bent cereals from spilling out of the transfer area of the left and right scraping transfer devices 24A and 24B together with the cutting.

図7および図13に示すように、左右の掻込搬送装置24A,24Bは、それらの平面に対する垂直方向から各掻込搬送装置24A,24Bを見た場合に、それらの掻込搬送機構71A,71Bの掻き込み搬送領域で、掻込ベルト74A,74Bの突出部74a,74bの先端が描く軌跡K1a,K1bが、可動刃68および固定刃69の先端と車体前後方向で略一致するように構成してある。   As shown in FIGS. 7 and 13, the left and right scavenging and transporting devices 24A and 24B have their scrambling and transporting mechanisms 71A and 71A when viewed from the direction perpendicular to their planes. The trajectories K1a and K1b drawn by the leading ends of the protrusions 74a and 74b of the scavenging belts 74A and 74B in the scooping and transporting area 71B are configured to substantially coincide with the leading ends of the movable blade 68 and the fixed blade 69 in the vehicle longitudinal direction. It is.

これにより、各掻込ベルト74A,74Bの突出部74a,74bが、刈り取り前の穀稈に作用して変形することを抑制することができ、その変形による耐久性の低下を抑制することができる。また、突出部74a,74bの変形を抑制することにより、刈り取り直後の穀稈を、左右の掻込ベルト74A,74B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、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とともに、搬送遅れに起因した穀稈の搬送姿勢の乱れによる穀粒回収率の低下を防止することができる。   Thereby, it can suppress that protrusion part 74a, 74b of each rake belt 74A, 74B acts on the grain straw before cutting, and can suppress the fall of durability by the deformation | transformation. . Moreover, by suppressing the deformation of the projecting portions 74a, 74b, the culm immediately after cutting can be quickly squeezed and conveyed toward the culm passing portion 27 by the left and right rake belts 74A, 74B. It is possible to improve the efficiency of scraping and transporting the culm by the left and right scraping and transporting devices 24A and 24B, and to prevent a decrease in the grain recovery rate due to the disorder of the transporting posture of the culm due to the transport delay. .

図7および図13に示すように、左右の掻込搬送装置24A,24Bは、それらの平面に対する垂直方向から各掻込搬送装置24A,24Bを見た場合に、各案内部材73A,73Bの案内作用部73a,73bが可動刃68および固定刃69の先端よりも車体後方側に位置するように、好ましくは、可動刃68および固定刃69の車体前後方向での刈取作用範囲の中間部よりも車体後方側に位置するように構成してある。   As shown in FIGS. 7 and 13, the left and right scavenging and conveying devices 24A and 24B guide the guide members 73A and 73B when the scrambling and conveying devices 24A and 24B are viewed from the direction perpendicular to their planes. Preferably, the action portions 73a and 73b are located on the rear side of the vehicle body with respect to the distal ends of the movable blade 68 and the fixed blade 69, preferably more than the middle portion of the cutting action range of the movable blade 68 and the fixed blade 69 in the longitudinal direction of the vehicle body. It is configured to be located on the rear side of the vehicle body.

これにより、案内部材73A,73Bが、車体の走行に伴って、刈り取り前の穀稈に接当して、その穀稈を車体の進行方向に向けて押し曲げるようになることを防止することができる。その結果、その押し曲げに起因して、押し曲げられた穀稈が、刈り取りとともに左右の掻込搬送装置24A,24Bの搬送領域から外れてこぼれ落ちることを防止することができる。   Accordingly, it is possible to prevent the guide members 73A and 73B from coming into contact with the culm before cutting and pushing the culm toward the traveling direction of the vehicle body as the vehicle travels. it can. As a result, it is possible to prevent the pushed and bent cereals from spilling out of the transfer area of the left and right scraping transfer devices 24A and 24B together with the cutting.

図7および図13に示すように、左右の掻込搬送装置24A,24Bは、それらの平面に対する垂直方向から各掻込搬送装置24A,24Bを見た場合に、左右のパッカ72A,72Bの突出部72a,72bの先端が描く軌跡K2a,K2bの前端が、可動刃68および固定刃69の先端と車体前後方向で略一致するように構成してある。   As shown in FIGS. 7 and 13, the left and right scavenging and conveying devices 24A and 24B are projected from the left and right packers 72A and 72B when viewed from the direction perpendicular to their planes. The front ends of the trajectories K2a and K2b drawn by the tips of the portions 72a and 72b are configured to substantially coincide with the tips of the movable blade 68 and the fixed blade 69 in the longitudinal direction of the vehicle body.

これにより、刈り取り直後の穀稈を、左右のパッカ72A,72B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、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とともに、搬送遅れに起因した穀稈の搬送姿勢の乱れによる穀粒回収率の低下を防止することができる。   As a result, the cereal immediately after cutting can be quickly scraped and conveyed by the left and right packers 72A and 72B toward the cereal passing part 27. As a result, the stalks are scraped by the left and right scraping and conveying devices 24A and 24B. In addition to being able to improve the transport efficiency, it is possible to prevent the grain recovery rate from being lowered due to the disordered transport posture of the culm due to the transport delay.

ちなみに、左右の掻込搬送装置24A,24Bを、それらの平面に対する垂直方向から各掻込搬送装置24A,24Bを見た場合に、それらの掻込搬送機構71A,71Bの掻き込み搬送領域で、左右のパッカ72A,72Bの突出部72a,72bの先端が描く軌跡K2a,K2bの前端が、可動刃68および固定刃69の先端と車体前後方向で一致するように構成してもよい。   By the way, when the left and right scraping and conveying devices 24A and 24B are viewed from the direction perpendicular to their planes, the scraping and conveying devices 71A and 71B are in the scraping and conveying region of the respective scraping and conveying mechanisms 71A and 71B. You may comprise so that the front end of locus | trajectory K2a and K2b which the front-end | tip of protrusion part 72a, 72b of left and right packers 72A and 72B draws may correspond with the front-end | tip of the movable blade 68 and the fixed blade 69 in a vehicle body front-back direction.

図4、図5および図7〜9に示すように、刈刃駆動装置70は、左伝動軸47よりも車体横外方側の位置に位置するように中間部材36の左端部に配備してある。   As shown in FIGS. 4, 5, and 7 to 9, the cutting blade driving device 70 is provided at the left end portion of the intermediate member 36 so as to be positioned on the laterally outer side of the vehicle body with respect to the left transmission shaft 47. is there.

これにより、刈取装置23により刈り取った穀稈の株元側が刈刃駆動装置70に接触することを確実に防止することができ、結果、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。   Thereby, it can prevent reliably that the stockholder side of the grain cocoon cut by the reaping device 23 contacts the cutting blade driving device 70, and as a result, the conveyance posture of the corn straw is disturbed by the contact. 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 avoided in advance.

また、刈刃駆動装置70が、搭乗運転部2が隣接せずに開放される刈取搬送部3の左端部に位置することにより、刈刃駆動装置70の組み付けやメンテナンスが行ないやすくなる。   Further, since the cutting blade driving device 70 is located at the left end portion of the cutting conveyance unit 3 that is opened without the boarding operation unit 2 being adjacent to the cutting driving unit 2, the cutting blade driving device 70 can be easily assembled and maintained.
