Description

本発明は、エンジンからの動力を複数の被駆動機器に伝達する伝動手段を備えたコンバインの伝動構造に関する。   The present invention relates to a power transmission structure for a combine that includes power transmission means for transmitting power from an engine to a plurality of driven devices.

上記のようなコンバインの伝動構造としては、エンジンからの動力を第1カウンター軸などを介してカウンタケースの第2出力軸に伝達し、第2出力軸から一方の伝動ベルトを介して脱穀装置に備えた被駆動機器である唐箕及び補助ブロアに伝達し、又、第2出力軸から他方の伝動ベルトを介して、脱穀装置に備えた被駆動機器である1番物搬送用の横送りスクリュコンベア、2番物搬送用の横送りスクリュコンベア、補助ブロア、揺動選別ケースの揺動駆動軸、チョッパ、及び排塵ブロアに伝達するように構成したものがある(例えば特許文献1参照)。   As the above-described combine transmission structure, the power from the engine is transmitted to the second output shaft of the counter case via the first counter shaft and the like, and from the second output shaft to the threshing device via one transmission belt. A transversal screw conveyor for conveying the first item, which is a driven device provided to the threshing device, transmitted from the second output shaft via the other transmission belt to the red pepper and auxiliary blower which are provided driven devices There is one configured to transmit to a horizontal feed screw conveyor for conveying the second article, an auxiliary blower, a swing drive shaft of a swing sorting case, a chopper, and a dust blower (for example, see Patent Document 1).

特開平11−266670号公報(段落番号0022〜0024、図4〜5)JP-A-11-266670 (paragraph numbers 0022 to 0024, FIGS. 4 to 5)

前記特許文献1に記載の伝動構造では、第2出力軸に伝達したエンジンからの動力を、他方の伝動ベルトを介して、風力選別用の強い選別風を得るためや高い細断能力を得るために高速回転させる補助ブロアやチョッパなどとともに各横送りスクリュコンベアに伝達するように構成していることから、各横送りスクリュコンベアに伝達する動力を十分に減速することが難しくなっている。そのため、各横送りスクリュコンベアをそのスクリュによる穀粒の損傷が生じ難い低速で駆動することが難しくなり、各横送りスクリュコンベアによる搬送の際に穀粒が損傷する不都合を招く虞があり、特に比較的軟らかくて損傷し易い大豆などを収穫対象とするコンバインにおいては改善の余地がある。   In the transmission structure described in Patent Document 1, the power from the engine transmitted to the second output shaft is obtained through the other transmission belt in order to obtain a strong sorting wind for wind sorting or to obtain a high shredding ability. Since it is configured so as to be transmitted to each lateral feed screw conveyor together with an auxiliary blower and a chopper that are rotated at a high speed, it is difficult to sufficiently decelerate the power transmitted to each lateral feed screw conveyor. Therefore, it is difficult to drive each transverse feed conveyor at a low speed at which it is difficult to damage the grain due to the screw, which may cause inconvenience that the grain is damaged during conveyance by each transverse feed conveyor. There is room for improvement in combine harvesters that are relatively soft and easily damaged.

本発明の目的は、搬送スクリュによる搬送で穀粒が損傷することに起因した穀粒品質の低下を防止することにある。   The objective of this invention is preventing the fall of the grain quality resulting from a grain being damaged by conveyance by a conveyance screw.

本発明の第1の課題解決手段では、
エンジンからの動力を複数の被駆動機器に伝達する伝動手段を備えたコンバインの伝動構造において、
前記伝動手段を、前記エンジンからの動力を前記複数の被駆動機器のうちの唐箕に伝達し、前記唐箕の唐箕軸にて高速伝動系と低速伝動系とに分岐し、前記低速伝動系からの低速動力を前記複数の被駆動機器のうちの搬送スクリュに伝達するように構成してある。
In the first problem solving means of the present invention,
In the transmission structure of a combine equipped with transmission means for transmitting power from the engine to a plurality of driven devices,
The transmission means transmits the power from the engine to the rotary drive of the plurality of driven devices, branches into a high-speed transmission system and a low-speed transmission system at the rotary shaft of the rotary drive, and from the low-speed transmission system Low-speed power is configured to be transmitted to the conveying screw among the plurality of driven devices.

この課題解決手段によると、エンジンからの動力を低速伝動系により十分に減速した後に搬送スクリュに伝達することができ、これにより、搬送スクリュをそのスクリュによる穀粒の損傷が生じ難い低速で駆動することが可能になり、搬送スクリュによる搬送で穀粒が損傷する虞を防止することができる。   According to this problem solving means, the power from the engine can be transmitted to the conveying screw after being sufficiently decelerated by the low-speed transmission system, and thereby the conveying screw is driven at a low speed that is unlikely to cause grain damage by the screw. This makes it possible to prevent the grain from being damaged by the conveyance by the conveyance screw.

従って、搬送スクリュによる搬送で穀粒が損傷することに起因した穀粒品質の低下を防止することができる。   Accordingly, it is possible to prevent the grain quality from being deteriorated due to the grain being damaged by the conveyance by the conveyance screw.

本発明の第2の課題解決手段では、上記第1の課題解決手段において、
前記伝動手段を、前記エンジンからの動力を前記唐箕軸の一端部に伝達し、かつ、前記唐箕軸の一端部から前記低速伝動系を分岐するように構成してある。
In the second problem solving means of the present invention, in the first problem solving means,
The transmission means is configured to transmit power from the engine to one end portion of the rod shaft, and to branch the low-speed transmission system from one end portion of the rod shaft.

この課題解決手段によると、唐箕軸の一端部に伝達したエンジンからの動力を唐箕軸の他端部から低速伝動系を分岐する場合に比較して唐箕軸に掛かる負荷を軽減することができる。   According to this problem solving means, it is possible to reduce the load applied to the tang shaft compared with the case where the power from the engine transmitted to one end portion of the tang shaft is branched from the other end portion of the tang shaft.

その結果、エンジンからの動力を唐箕軸を経由して各被駆動機器に伝達する構成でありながら唐箕軸の耐久性の向上を図ることができる。   As a result, the durability of the red pepper shaft can be improved while the power from the engine is transmitted to each driven device via the red collar shaft.

本発明の第3の課題解決手段では、上記第1又は2の課題解決手段において、
前記低速伝動系を、前記唐箕軸から第1減速機構を介してアイドラ軸に減速伝動し、前記アイドラ軸から第2減速機構を介して前記搬送スクリュに減速伝動する2段減速式に構成してある。
In the third problem solving means of the present invention, in the first or second problem solving means,
The low-speed transmission system is configured as a two-stage reduction type in which the transmission is transmitted from the hot shaft to the idler shaft through the first reduction mechanism, and is transmitted from the idler shaft to the conveying screw through the second reduction mechanism. is there.

この課題解決手段によると、唐箕軸から単一の減速機構を介して搬送スクリュに減速伝動する場合に比較して、各減速機構での変速比を小さくすることができ、各減速機構に備える伝動回転体として小径のものを採用することができ、伝動回転体などの他物との干渉を容易に回避することができる。   According to this problem solving means, it is possible to reduce the gear ratio in each speed reduction mechanism, compared to the case where the speed reduction shaft is transmitted to the conveying screw through a single speed reduction mechanism, and the transmission provided for each speed reduction mechanism. A rotating body having a small diameter can be adopted, and interference with another object such as a transmission rotating body can be easily avoided.

これにより、唐箕軸から搬送スクリュへの減速伝動が行い易くなるとともに、唐箕軸から他の被駆動機器への伝動も行い易くなり、結果、伝動手段の組み付け性やメンテナンス性を向上させることができる。   As a result, it becomes easy to perform the deceleration transmission from the Karatsu shaft to the conveying screw, and also to facilitate the transmission from the Karatsu shaft to other driven devices, and as a result, it is possible to improve the assembling property and maintainability of the transmission means. .

本発明の第4の課題解決手段では、上記第1〜3の課題解決手段のいずれか一つにおいて、
前記複数の被駆動機器として、前記搬送スクリュとしての1番物搬送用の1番搬送スクリュ及び2番物搬送用の2番搬送スクリュと、粗選別用の選別風を供給する副唐箕及び2番物選別用の選別風を供給する2番唐箕とを備え、
前記伝動手段を、前記低速伝動系からの低速動力を前記1番搬送スクリュ及び前記2番搬送スクリュに伝達し、前記高速伝動系からの高速動力を前記副唐箕及び前記2番唐箕に伝達するように構成してある。
In the fourth problem solving means of the present invention, in any one of the first to third problem solving means,
As the plurality of driven devices, the first transport screw for transporting the first object and the second transport screw for transporting the second object as the transport screws, the sub-carp for supplying the sorting air for rough sorting, and the second With No. 2 Kara to supply sorting wind for sorting items,
The transmission means transmits low-speed power from the low-speed transmission system to the first transfer screw and the second transfer screw, and transmits high-speed power from the high-speed transmission system to the sub-tang and second combination. It is configured.

この課題解決手段によると、1番搬送スクリュ及び2番搬送スクリュを、それらのスクリュによる穀粒の損傷が生じ難い低速で駆動することができ、1番搬送スクリュ及び2番搬送スクリュによる搬送で穀粒が損傷する虞を防止することができる。その結果、1番搬送スクリュ及び2番搬送スクリュによる搬送で穀粒が損傷することに起因した穀粒品質の低下を防止することができる。   According to this problem solving means, the first conveying screw and the second conveying screw can be driven at a low speed at which grain damage caused by those screws is difficult to occur, and the first conveying screw and the second conveying screw can transfer the grain. The possibility that the grains are damaged can be prevented. As a result, it is possible to prevent the grain quality from being deteriorated due to the grain being damaged by the transport by the first transport screw and the second transport screw.

又、副唐箕及び2番唐箕を唐箕とともに高速回転駆動させることができ、これらの各唐箕から強い選別風を発生させることができる。その結果、風力選別による選別精度の向上を図ることができる。   Further, the sub-red pepper and the second hot pot can be rotated at high speed together with the hot pot, and a strong sorting wind can be generated from each of these hot pots. As a result, it is possible to improve the sorting accuracy by wind sorting.

本発明の第5の課題解決手段では、上記第1〜4の課題解決手段のいずれか一つにおいて、
前記伝動手段に、前記低速伝動系からの低速動力を前記複数の被駆動機器のうちの扱胴に伝達する扱胴伝動系を装備してある。
In a fifth problem solving means of the present invention, in any one of the first to fourth problem solving means,
The transmission means is equipped with a handling cylinder transmission system that transmits low-speed power from the low-speed transmission system to a handling cylinder among the plurality of driven devices.

この課題解決手段によると、低速伝動系からの低速動力で負荷の大きい扱胴を駆動することができ、扱胴伝動系での変速比を変更することにより、扱胴の回転速度を、比較的硬くて損傷し難い稲や麦などに扱き処理を施すのに適した高速と、比較的軟らかくて損傷し易い大豆などに扱き処理を施すのに適した低速とに切り換えることができる。   According to this problem solving means, it is possible to drive a handling cylinder having a large load with low-speed power from the low-speed transmission system, and by changing the gear ratio in the handling cylinder transmission system, It is possible to switch between a high speed suitable for handling rice and wheat that are hard and difficult to damage, and a low speed suitable for handling soybean that is relatively soft and easily damaged.

つまり、損傷し難い稲や麦などを収穫する場合には、扱胴の回転速度を稲麦用の高速に切り換えることによって処理能力の向上を図ることができ、損傷し易い大豆などを収穫する場合には、扱胴の回転速度を大豆用の低速に切り換えることによって扱き処理時の損傷による品質の低下を防止することができる。   In other words, when harvesting difficult-to-damage rice or wheat, the processing capacity can be improved by switching the rotation speed of the barrel to the high speed for rice and wheat. In this case, the deterioration of quality due to damage during handling can be prevented by switching the rotation speed of the barrel to a low speed for soybeans.

そして、このように扱胴の回転速度を切り換えるようにしても、搬送スクリュへは低速伝動系からの一定の低速動力を伝達することから、扱胴用の伝動機構での変速比の変更にかかわらず搬送スクリュの駆動速度を一定に維持することができる。   Even if the rotation speed of the cylinder is changed in this way, a constant low-speed power from the low-speed transmission system is transmitted to the conveying screw, so that the gear ratio in the transmission mechanism for the cylinder is changed. Therefore, the driving speed of the conveying screw can be kept constant.

その結果、扱胴の回転速度を大豆用の低速に切り換えた場合であっても、その切り換えに伴って搬送スクリュの駆動速度が低速になって搬送スクリュの搬送性能が低下する不都合の発生を防止することができる。   As a result, even when the rotation speed of the handling cylinder is switched to a low speed for soybeans, the driving speed of the conveying screw is lowered with the switching, and the inconvenience that the conveying performance of the conveying screw is lowered is prevented. can do.

本発明の第6の課題解決手段では、上記第5の課題解決手段において、
前記伝動手段に、穀稈を刈り取って脱穀装置に搬送する刈取搬送装置に前記低速伝動系からの低速動力を伝達する刈取搬送伝動系を前記扱胴伝動系と並列に装備してある。
According to a sixth problem solving means of the present invention, in the fifth problem solving means,
The transmission means is equipped in parallel with the barrel transmission system with a cutting and conveying transmission system that transmits low-speed power from the low-speed transmission system to a harvesting and conveying apparatus that harvests and conveys the cereal husk.

この課題解決手段によると、低速伝動系からの低速動力で負荷の大きい刈取搬送装置を駆動することができる。そして、前述したように扱胴伝動系での変速比を変更して扱胴の回転速度を切り換えるようにしても、刈取搬送装置へは扱胴用の伝動機構を介さずに伝動することから、扱胴伝動系での変速比の変更にかかわらず刈取搬送装置の駆動速度を一定に維持することができる。   According to this problem solving means, it is possible to drive the cutting and conveying apparatus having a large load with the low speed power from the low speed transmission system. And, as described above, even if the gear ratio in the barrel transmission system is changed and the rotation speed of the barrel is changed, the cutting and conveying device is transmitted without going through the transmission mechanism for the barrel, The driving speed of the cutting and conveying apparatus can be kept constant regardless of the change of the gear ratio in the barrel transmission system.

その結果、扱胴の回転速度を大豆用の低速に切り換えた場合であっても、その切り換えに伴って刈取搬送装置の駆動速度が低速になって刈取搬送装置での刈り取り性能や搬送速度が低下する不都合の発生を防止することができる。   As a result, even when the rotation speed of the handling cylinder is switched to a low speed for soybeans, the driving speed of the cutting and conveying device is lowered with the switching, and the cutting performance and conveying speed of the cutting and conveying device are reduced. It is possible to prevent the occurrence of inconvenience.

本発明の第7の課題解決手段では、上記第5の課題解決手段において、
前記伝動手段に、穀稈を刈り取って脱穀装置に搬送する刈取搬送装置に前記低速伝動系からの低速動力を伝達する刈取搬送伝動系を備え、前記刈取搬送伝動系の伝動方向下手側に前記扱胴伝動系を直列に連動連結してある。
In the seventh problem-solving means of the present invention, in the fifth problem-solving means,
The transmission means includes a cutting and conveying transmission system that transmits low-speed power from the low-speed transmission system to a cutting and conveying apparatus that harvests and conveys cereal husks to the threshing device, and the handle is disposed on the lower side in the transmission direction of the cutting and conveying transmission system. The body transmission system is linked in series.

この課題解決手段によると、低速伝動系からの低速動力で負荷の大きい刈取搬送装置を駆動することができる。そして、前述したように扱胴伝動系での変速比を変更して扱胴の回転速度を切り換えるようにしても、刈取搬送装置への伝動には扱胴伝動系を介していないことから、扱胴伝動系での変速比の変更にかかわらず刈取搬送装置の駆動速度を一定に維持することができる。   According to this problem solving means, it is possible to drive the cutting and conveying apparatus having a large load with the low speed power from the low speed transmission system. Even if the gear ratio in the barrel transmission system is changed and the rotation speed of the barrel is switched as described above, the transmission to the cutting and conveying apparatus is not via the barrel transmission system. The driving speed of the cutting and conveying device can be kept constant regardless of the change of the gear ratio in the trunk transmission system.

その結果、扱胴の回転速度を大豆用の低速に切り換えた場合であっても、その切り換えに伴って刈取搬送装置の駆動速度が低速になって刈取搬送装置での刈り取り性能や搬送速度が低下する不都合の発生を防止することができる。   As a result, even when the rotation speed of the handling cylinder is switched to a low speed for soybeans, the driving speed of the cutting and conveying device is lowered with the switching, and the cutting performance and conveying speed of the cutting and conveying device are reduced. It is possible to prevent the occurrence of inconvenience.

It is configured to be connected to the handling cylinder shaft 18 so as to rotate integrally around the trunk shaft 18 clockwise as viewed from the front.

掻込部33は、前細りの円錐台状に形成した胴部分35の外周面に掻き込み搬送用の2枚の螺旋羽根36を装備して、扱胴軸18を中心に正面視右回りに回転することで、穀稈案内板29が案内するフィーダ12からの刈取穀稈の全体を、2枚の螺旋羽根36によって後方の受網16や上部カバー26と扱き処理部34との間の扱き処理空間S1に掻き入れるスクリュ搬送式に構成してある。尚、掻込部33としては、胴部分35に螺旋羽根36に代えて整梳歯や扱歯などの異なる掻込部材を備えたものであってもよい。   The scraping portion 33 is equipped with two spiral blades 36 for scraping and transporting on the outer peripheral surface of the barrel portion 35 formed in the shape of a truncated cone, and rotates clockwise around the barrel shaft 18. By rotating, the entire harvested cereal from the feeder 12 guided by the culm guide plate 29 is handled between the rear receiving net 16 and the upper cover 26 and the handling processing unit 34 by two spiral blades 36. It is configured as a screw conveyance type that is scraped into the processing space S1. In addition, as the scraping part 33, it replaces with the spiral blade | wing 36 in the trunk | drum 35, and may be equipped with different scraping members, such as a clinching tooth and a tooth-handling.

扱き処理部34は、その前端又は後端を形成する円盤状の支持板37,38を、前端用の支持板37が掻込部33の後端に連接し、後端用の支持板38が後側縦板部材28の直前に位置するように扱胴軸18に装備してある。又、円盤状の仕切板39を、扱き処理部34の前後中間部位となる前後の支持板37,38の中間又は略中間に位置するように扱胴軸18に装備してある。そして、これらの支持板37,38及び仕切板39の各外周部に、前後の支持板37,38にわたる長さを有する複数(例えば6本)の棒状部材40を、扱胴軸18に沿う前後向き姿勢で扱胴軸18から等距離の位置に扱胴19の周方向に等間隔で並ぶように連結し、かつ、各棒状部材40に、複数の扱歯41を棒状部材40から扱胴19の外方に向けて突出する姿勢で前後方向に設定間隔をあけて並ぶように配備してある。これにより、扱室17の内部に扱室17に連通する内部空間S2が形成されたバータイプ処理胴を構成してある。   The handling processing unit 34 includes disk-shaped support plates 37 and 38 that form the front end or the rear end thereof, the front end support plate 37 is connected to the rear end of the scoring portion 33, and the rear end support plate 38 is The barrel 18 is equipped so as to be positioned immediately before the rear vertical plate member 28. In addition, a disc-shaped partition plate 39 is mounted on the handling cylinder shaft 18 so as to be located in the middle or substantially in the middle of the front and rear support plates 37 and 38 which are the front and rear intermediate portions of the handling processing unit 34. Then, a plurality of (for example, six) rod-like members 40 having a length over the front and rear support plates 37 and 38 are provided on the outer peripheral portions of the support plates 37 and 38 and the partition plate 39 in the front and rear directions along the barrel 18. In the orientation posture, they are connected at equal distances from the barrel 18 so as to be arranged at equal intervals in the circumferential direction of the barrel 19, and a plurality of teeth 41 are connected to each rod-shaped member 40 from the rod-shaped member 40 to the barrel 19. Are arranged so as to be lined up at a set interval in the front-rear direction with a posture protruding outward. As a result, a bar type processing cylinder is formed in which an internal space S <b> 2 communicating with the chamber 17 is formed inside the chamber 17.

これにより、扱き処理部34は、扱胴軸18を中心に正面視右回りに回転することで、受網16や上部カバー26との間の扱き処理空間S1に位置する刈取穀稈に扱歯41の打撃や扱歯41の梳き込みなどによる扱き処理を施し、この扱き処理で得た処理物の内部空間S2への入り込みを許容し、扱き処理空間S1の処理物と内部空間S2の処理物とを攪拌しながら、これらの処理物に棒状部材40及び扱歯41の打撃や扱歯41の梳き込みなどによる扱き処理を施すように構成してある。   As a result, the handling unit 34 rotates clockwise about the handling cylinder shaft 18 in the front view so that a tooth handling is applied to the harvested cereal culm located in the handling processing space S1 between the receiving net 16 and the upper cover 26. 41, a handling process such as hammering of the teeth 41 and the handling of the tooth handling 41 is performed, and the processed material obtained by this handling process is allowed to enter the internal space S2, and the processed material in the processing space S1 and the processed material in the internal space S2 These processing products are configured to be subjected to a handling process such as striking the bar-shaped member 40 and the tooth handling 41 or scooping the tooth handling 41.

そして、扱き処理部34の内部空間S2を扱き処理用の処理空間に使用することにより、大量の刈取穀稈を扱室17に供給した場合であっても、処理空間での処理物の滞留や処理空間の飽和を回避することができ、これにより、処理物の滞留や処理空間の飽和に起因して十分な扱き処理が行われないまま処理物が受網16から漏下する、あるいは、扱き処理に要する負荷が増大して扱胴19に対する伝動系が損傷する、などの不都合の発生を防止することができる。   Then, by using the internal space S2 of the handling processing unit 34 as a processing space for handling processing, even when a large amount of harvested cereal meal is supplied to the handling chamber 17, the retention of the processed material in the processing space or Saturation of the processing space can be avoided, so that the processing material leaks from the receiving network 16 without sufficient handling processing due to stagnation of the processing material and saturation of the processing space, or It is possible to prevent the occurrence of inconvenience such as an increase in the load required for processing and damage to the transmission system for the handling cylinder 19.

仕切板39は、扱き処理部34に形成した内部空間S2の上手側部分を後側から塞ぐように扱胴軸18を中心にして配備した円板で構成してあり、これにより、脱穀処理物量が減少する扱き処理部34の前後中間部位においては、仕切板39が、扱き処理部34の内部空間S2での脱穀処理物の脱穀処理方向下手側への流動を阻止し、扱き処理部34の回転とともに脱穀処理物を扱き処理部34の周囲に導いて、脱穀処理物に対する扱歯41などの打撃や梳き込みなどによる脱穀や、単粒化穀粒の受網16からの漏下を促すようになることから、脱穀処理物に含まれる単粒化穀粒や未脱粒穀稈などが扱き処理部34の内部空間S2を素通りして、脱粒穀稈とともに脱穀処理方向下手側端部の排稈口32から排出されることに起因した3番ロスの発生を阻止することができる。   The partition plate 39 is composed of a disc disposed around the handling cylinder shaft 18 so as to close the upper side portion of the internal space S2 formed in the handling processing unit 34 from the rear side. In the intermediate part before and after the handling processing unit 34 where the handling processing unit 34 decreases, the partition plate 39 prevents the threshing processed product from flowing downward in the threshing processing direction in the internal space S2 of the handling processing unit 34. The threshing processed product is guided to the periphery of the processing unit 34 along with the rotation so as to promote threshing by hitting or punching the tooth handling 41 or the like with respect to the threshing processed product, or leakage of the single grain from the receiving net 16. Therefore, single grains and unthreshed grains included in the threshing processed material pass through the internal space S2 of the processing section 34, and the threshing cereal and the lower end portion in the threshing processing direction are removed. No. 3 loss due to being discharged from the mouth 32 It is possible to prevent the occurrence.

又、複数の扱歯41だけでなく複数の棒状部材40までもが、扱室内の処理物に作用する扱き処理部材として機能することから、脱穀性能や脱穀効率の向上を図ることができる。   In addition, since not only the plurality of teeth 41 but also the plurality of rod-shaped members 40 function as a handling member that acts on the processed material in the handling chamber, threshing performance and threshing efficiency can be improved.

尚、棒状部材40には、丸パイプ鋼材、角パイプ鋼材、丸棒鋼材、角棒鋼材、アングル材、又はチャンネル材などを採用することができる。各扱歯41には、丸棒鋼材、角棒鋼材、丸パイプ鋼材、又は角パイプ鋼材などを採用することができる。   The rod-shaped member 40 may be a round pipe steel material, a square pipe steel material, a round bar steel material, a square bar steel material, an angle material, a channel material, or the like. For each tooth 41, a round bar steel, a square bar steel, a round pipe steel, a square pipe steel, or the like can be used.

唐箕21は、揺動選別手段20の前下方に配備してあり、左右向きの唐箕軸51を中心に左側面視左回りに回転することで選別風を発生させるとともに、この選別風を、唐箕ケース52の後下部に形成した吹出口52Aから、後上方のグレンシーブ49と1番回収部24との間、グレンシーブ49の全域、及び、グレンシーブ49と2番チャフシーブ50との間、を吹き抜ける精選別用として供給するように構成してある。   The red pepper 21 is arranged in front of and below the swinging sorting means 20 and generates a sorting wind by rotating counterclockwise in the left side view about the left-right facing shaft 51, and this sorting wind is Fine sorting through the blowout opening 52A formed in the lower rear part of the case 52, blows through the rear and upper Glen sheave 49 and No. 1 recovery part 24, the entire area of the Glen sheave 49, and between the Glen sheave 49 and No. 2 chaff sheave 50. It is configured to be supplied for use.

唐箕21の吹出口52Aには、唐箕21からの選別風を、グレンシーブ49及びグレンシーブ49の底面近くを吹き抜ける上層風と、1番回収部24の上方近傍を吹き抜ける下層風とに分ける風向板52Bを配備してある。風向板52Bは、上層風の流速を高めるための絞り面52Baを上部に備え、下層風の吹き出し方向を水平又は水平近くに修正する風向部52Bbを後端部から後下方向きに延出させてある。   At the air outlet 52A of the carp 21, a wind direction plate 52B that divides the sorting air from the carp 21 into an upper wind that blows near the bottom surface of the grain sieve 49 and the grain sheave 49 and a lower wind that blows near the upper part of the first recovery unit 24. It has been deployed. The wind direction plate 52B is provided with a throttle surface 52Ba for increasing the flow velocity of the upper wind at the upper part, and a wind direction part 52Bb for correcting the blowing direction of the lower wind to be horizontal or nearly horizontal is extended from the rear end part to the rear lower direction. is there.

これにより、唐箕21からの選別風を、グレンシーブ49から漏下して1番回収部24に流下する処理物、及び、グレンシーブ49による篩い選別中の処理物に前下方から作用させて、それらの処理物から比重の小さい稈屑などの塵埃を吹き分けて後上方に風力搬送する風力選別を行うことができ、この風力選別により、稈屑などの塵埃の1番回収部24への混入を防止しながらグレンシーブ49から漏下する単粒化穀粒を1番回収部24に回収する1番回収処理を精度良く行なうことができる。   As a result, the sorting air from the tang rice cake 21 leaks from the grain sieve 49 and flows down to the first collecting unit 24, and the treated substance being screened by the grain sieve 49 from the front and lower side, It is possible to perform wind sorting that blows dust such as soot dust with a small specific gravity from the processed material and then winds it upward, and this wind sorting prevents dust such as soot from entering the No. 1 recovery unit 24. However, the 1st recovery process which collects the single grain which leaks from the Glen sieve 49 to the 1st recovery part 24 can be performed with sufficient accuracy.

特に、グレンシーブ49から漏下した直後の処理物には、流速を高めた上層風が作用することにより、比較的大きい稈屑などを効率良く風力選別することができ、比較的大きい稈屑などが取り除かれて1番回収部24の近くまで流下した処理物には、1番回収部24の上方近傍を水平又は略水平に吹き抜ける下層風が作用することにより、この処理物に残留する比較的小さい稈屑などを精度良く風力選別することができる。   In particular, the upper layer wind with an increased flow velocity acts on the processed material immediately after leaking from the grain sieve 49, so that relatively large soot can be efficiently sorted by wind power, and relatively large soot is generated. The processed material that has been removed and has flowed down to the vicinity of the first recovery unit 24 is affected by the lower wind that blows horizontally or substantially horizontally above the first recovery unit 24, so that it remains relatively small in the processed product. Wind power can be accurately sorted for sawdust.

A selection wind is generated by rotating counterclockwise in the left side view about the auxiliary sub-shaft shaft 53 in the direction, and this sort air is supplied from the outlet 54A formed in the lower rear part of the sub-tan case 54 for rough selection. A chaff sheave 46, a fine sorting grain pan 48, and an upper wind direction plate 55 provided on the bottom surface of the grain pan 45, and a lower wind direction plate 56 extending horizontally forward from the fine sorting grain pan 48, It is configured so as to be supplied for rough sorting that blows through between the grain sheave 49 and between the Strollac 47 and the second chaff sheave 50. The outer diameter (rotating diameter) of the auxiliary tongue 22 in a side view is set to ½ (or substantially ½) of the outer diameter (rotating diameter) of the tongue 21 in a side view.

これにより、副唐箕22からの選別風を、上側風向板55と下側風向板56との間の後窄みの空間を通して流速を高めた状態で、チャフシーブ46を漏下して精選別用のグレンパン48及びグレンシーブ49に流下する処理物や、受網16の後端部及びストローラック47から流下する処理物に効果的に作用させることができ、その結果、それらの処理物から比重の小さい稈屑などの塵埃を吹き分けて後上方に風力搬送する風力選別を良好に行うことができ、この風力選別により、稈屑などの塵埃のグレンシーブ49や2番チャフシーブ50への流下をより確実に抑制することができ、グレンシーブ49及び2番チャフシーブ50での選別効率や選別精度の向上を図ることができる。   As a result, the sorting wind from the auxiliary tang 22 is leaked through the chaff sheave 46 in a state where the flow velocity is increased through the space of the rear constriction between the upper wind direction plate 55 and the lower wind direction plate 56, and the fine wind is used for fine sorting. It is possible to effectively act on the processed material flowing down to the grain pan 48 and the grain sieve 49 and the processed material flowing down from the rear end portion of the receiving net 16 and the stroller 47. As a result, the processed material has a small specific gravity. The wind sorting that blows away dust such as scraps and winds it upwards can be performed well, and this wind sorting more reliably suppresses the flow of dust such as soot scraps to the Glen Sheave 49 and No. 2 Chaff Sheave 50. Therefore, it is possible to improve the sorting efficiency and sorting accuracy in the Glen sheave 49 and the second chaff sheave 50.

又、副唐箕22からの選別風がチャフシーブ46のチャフリップ板46Aの間を通過し難くなることから、副唐箕22からの選別風がチャフシーブ46のチャフリップ板46Aの間を勢いよく通過することに起因してチャフシーブ46からの漏下が抑制されて後方のストローラック47に移送される処理物が増えることによる選別効率の低下を防止することができる。   Further, since the sorting air from the sub-tang 22 becomes difficult to pass between the chaff plates 46A of the chaff sheave 46, the sorting air from the sub-tan 22 passes between the chaff plates 46A of the chaff sheave 46 vigorously. Therefore, the leakage from the chaff sheave 46 is suppressed, and the reduction of the sorting efficiency due to the increase in the amount of processed material transferred to the rear stroller 47 can be prevented.

2番唐箕23は、2番チャフシーブ50の前下方における1番回収部24と2番回収部25との間に配備してあり、左右向きの2番唐箕軸57を中心に左側面視左回りに回転することで選別風を発生させるとともに、この選別風を、2番唐箕ケース58の後上部に形成した吹出口58Aから、2番チャフシーブ50の下方を通過して2番チャフシーブ50の後端部から後上方に吹き抜ける2番選別用として、揺動選別手段20の後縦壁であるシーブケース44の後縦壁44Aに向けて供給するように構成してある。又、吹出口58Aは、その吹き出し方向下手側の端部が2番チャフシーブ50の前端と前後方向で一致又は略一致するように後方側に延出してあり、しかも、その上側及び下側の案内面が吹き出し方向下手側ほど上下間隔が狭くなる先窄み形状に形成してある。尚、吹出口58Aの上側の案内面は、側面視で逆V字状に屈曲した形状に形成してある。   The No. 2 Kara 23 is arranged between the No. 1 recovery part 24 and the No. 2 recovery part 25 in the front lower part of the No. 2 chaff sheave 50 and is turned counterclockwise as viewed from the left side around the No. 2 Kara axis 57 The sorting wind is generated by rotating to the rear of the second chaff sheave 50 from the outlet 58A formed at the upper rear portion of the second Karatsu case 58 and passing under the second chaff sheave 50. As for the second sorting that blows out rearward and upward from the section, it is configured to be supplied toward the rear vertical wall 44A of the sheave case 44 that is the rear vertical wall of the swing sorting means 20. Further, the outlet 58A extends rearward so that the end on the lower side in the blowing direction coincides or substantially coincides with the front end of the second chaff sheave 50 in the front-rear direction, and the upper and lower guides thereof. The surface is formed in a tapered shape in which the vertical interval becomes narrower toward the lower side in the blowing direction. The upper guide surface of the air outlet 58A is formed in a bent shape in an inverted V shape when viewed from the side.

つまり、2番唐箕23からの選別風を先窄み形状の吹出口58Aにより流速を高めた状態で2番チャフシーブ50の前端近くから吹き出させることができ、これにより、2番唐箕23からの選別風を2番チャフシーブ50を漏下して2番回収部25に流下する処理物に効果的に作用させることができ、その結果、その処理物から比重の小さい稈屑などの塵埃を吹き分けて、チャフリップ板50Aとの引っ掛かりで2番チャフシーブ50の後端部上に滞留する長い稈屑などとともに、2番チャフシーブ50の後端部から後上方に風力搬送する風力選別を良好に行うことができ、この風力選別により、稈屑などの塵埃の2番回収部25への混入を防止しながら2番チャフシーブ50から漏下する枝梗付き穀粒や二股粒などを2番回収部25に回収する2番回収処理を精度良く行なうことができる。   In other words, the sorting air from the No. 2 Karatsu 23 can be blown out from the vicinity of the front end of the No. 2 Chaff sheave 50 in a state where the flow velocity is increased by the tapered outlet 58A. The wind can effectively act on the processed material flowing down the second chaff sheave 50 and flowing down to the second recovery unit 25. As a result, dust such as sawdust having a small specific gravity is blown from the processed material. In addition to the long sawdust that stays on the rear end portion of the second chaff sheave 50 due to being caught with the chaff flip plate 50A, it is possible to satisfactorily perform wind sorting that winds the wind from the rear end portion of the second chaff sheave 50 to the rear upper side. It is possible to collect the grain and bifurcated grains that are leaked from the second chaff sheave 50 and to the second collection unit 25 while preventing the dust from the second collection unit 25 from entering dust such as sawdust. 2nd recovery processing can be performed accurately that.

又、2番唐箕23からの選別風が2番チャフシーブ50の前部側に配備したチャフリップ板50Aの間を通過し難くなることから、チャフシーブ46の後端部付近で合流した唐箕21及び副唐箕22からの選別風に影響を及ぼし難くなるとともに、2番唐箕23からの選別風が2番チャフシーブ50の前部側のチャフリップ板50Aの間を勢いよく通過することに起因して2番チャフシーブ50の前部側からの漏下が抑制されてシーブケース44の後方に移送される穀粒が増えることによる穀粒回収効率の低下を防止することができる。   Further, since the sorting wind from the No. 2 tang 23 becomes difficult to pass between the chaff plates 50 </ b> A arranged on the front side of the No. 2 chaff sheave 50, No. 2 due to the fact that the sorting wind from the No. 2 Karatsu 23 is not easily affected by the sorting wind from the No. 2 Kara 22 and passes between the cha-flip plates 50A on the front side of the No. 2 chaff sheave 50. Leakage from the front side of the chaff sheave 50 is suppressed, and a decrease in grain recovery efficiency due to an increase in the number of grains transferred to the rear of the sheave case 44 can be prevented.

回収部3Cにおいて、1番回収部24はグレンシーブ49から漏下した1番物を底部の1番物搬出領域に流下案内する側面視底窄まり形状に形成してある。2番回収部25は、2番チャフシーブ50から漏下した2番物を底部の2番物搬出領域に流下案内する側面視底窄まり形状に形成してある。又、2番回収部25の前部上方には、2番唐箕ケース58の吹出口58Aが前方側から覆うように延出している。   In the collecting unit 3C, the first collecting unit 24 is formed in a bottom-constricted shape in a side view that guides the first item leaked from the grain sieve 49 to the first item unloading region at the bottom. The second collecting part 25 is formed in a bottom-squeezed shape in side view that guides the second thing leaked from the second chaff sheave 50 to the second thing unloading area at the bottom. In addition, above the front part of the second collecting unit 25, the air outlet 58A of the second Chinese case 58 extends so as to cover from the front side.

1番回収部24の底部には、左右向きの1番スクリュ軸59を中心に左側面視左回りに回転することで、1番回収部24の1番物搬出領域まで流下した1番物を右方に搬送する1番搬送スクリュ60を配備してある。2番回収部25の底部には、左右向きの2番スクリュ軸61を中心に左側面視左回りに回転することで、2番回収部25の2番物搬出領域まで流下した2番物を右方に搬送する2番搬送スクリュ62を配備してある。   At the bottom of the first collecting part 24, the first thing flowing down to the first thing carrying-out area of the first collecting part 24 by rotating counterclockwise around the first screw shaft 59 facing left and right is seen. The 1st conveyance screw 60 conveyed to the right side is arranged. At the bottom of the second collecting part 25, the second thing that has flowed down to the second thing unloading area of the second collecting part 25 by rotating counterclockwise around the second screw shaft 61 facing left and right. A second conveying screw 62 that conveys to the right is provided.

1番搬送スクリュ60の右端部には、1番搬送スクリュ60が搬送した1番物を袋詰装置4の上部に揚送するバケット式の揚送コンベヤ63を連動連結してある。2番搬送スクリュ62の右端部には、2番搬送スクリュ62が搬送した2番物に再び扱き処理を施す再処理機構64、及び、この再処理機構64による再処理後の2番物を粗選別用のグレンパン45に還元搬送するスクリュ式の2番還元スクリュ65を連動連結してある。   At the right end of the first conveying screw 60, a bucket-type conveying conveyor 63 that conveys the first item conveyed by the first conveying screw 60 to the upper portion of the bagging device 4 is linked and connected. At the right end of the second conveying screw 62, a reprocessing mechanism 64 for re-handling the second object conveyed by the second conveying screw 62, and the second object after the reprocessing by the reprocessing mechanism 64 are roughened. A screw-type second reduction screw 65 that is reduced and conveyed to the sorting gren pan 45 is interlocked and connected.

A chopper 66 for discharging is disposed. The chopper 66 is disposed on the chopper shaft 69 that is directed to the left and right with respect to a plurality of fixed blades 68 that are aligned and arranged at regular intervals in the left and right direction inside the sewage cover 67 that is connected to the lower rear end of the threshing device 3.

図2及び図7に示すように、このコンバインでは、搭乗運転部7における運転座席71の下方にエンジン72を配備してあり、このエンジン72からの動力を、エンジン72から左方に延出した出力軸73において走行用と作業用とに分岐してある。   As shown in FIG. 2 and FIG. 7, in this combine, an engine 72 is arranged below the driver seat 71 in the boarding operation unit 7, and the power from the engine 72 extends leftward from the engine 72. The output shaft 73 is branched for traveling and working.

図7に示すように、走行用の動力は、エンジン72の出力軸73から走行用の伝動手段Aを介して左右のクローラ式走行装置6に伝達する。走行用の伝動手段Aは、ベルト伝動式の伝動機構74、静油圧式無段変速装置75、及び、トランスミッションケース76に内蔵したギア式伝動機構(図示せず)、などから構成してある。   As shown in FIG. 7, the driving power is transmitted from the output shaft 73 of the engine 72 to the left and right crawler type traveling devices 6 via the driving transmission means A.

作業用の伝動手段Bは、エンジン72からの動力を、エンジン72の出力軸73からベルト伝動式の伝動機構77を介して唐箕軸51の右端部に減速伝達し、その唐箕軸51の伝動方向上手側の端部となる右端部において高速伝動系Hと低速伝動系Lとに分岐してある。   The working transmission means B decelerates and transmits the power from the engine 72 from the output shaft 73 of the engine 72 to the right end portion of the tang shaft 51 via the belt transmission type transmission mechanism 77, and the transmission direction of the tang shaft 51. The right end which is the upper end is branched into a high speed transmission system H and a low speed transmission system L.

高速伝動系Hは、唐箕軸51の回転動力を、唐箕軸51の伝動方向下手側の端部となる左端部からベルト伝動式の第1伝動機構78を介して副唐箕軸53の左端部と2番唐箕軸57の左端部と中継軸79とに増速伝達し、中継軸79からベルト伝動式の第2伝動機構80を介してチョッパ軸69の左端部に増速伝達するように構成してある。   The high-speed transmission system H transmits the rotational power of the tang shaft 51 to the left end portion of the auxiliary tang shaft 53 from the left end portion, which is the end portion on the lower side of the transmission direction of the tang shaft 51, via the belt transmission type first transmission mechanism 78. The transmission speed is transmitted to the left end portion of the second tang shaft 57 and the relay shaft 79, and the speed increase transmission is transmitted from the relay shaft 79 to the left end portion of the chopper shaft 69 via the belt transmission type second transmission mechanism 80. It is.

低速伝動系Lは、唐箕軸51の回転動力を、唐箕軸51の右端部からベルト伝動式の第1減速機構81を介して左右向きのアイドラ軸82の右端部に減速伝達し、アイドラ軸82の左端部からベルト伝動式の第2減速機構83を介して1番スクリュ軸59の左端部と2番スクリュ軸61の左端部とに減速伝達する2段減速式に構成してある。又、2番スクリュ軸61の回転動力を、ベルト伝動式の第3伝動機構84を介して揺動選別手段20の揺動軸85に減速伝達するように構成してある。   The low speed transmission system L decelerates and transmits the rotational power of the rotary shaft 51 from the right end portion of the hot shaft 51 to the right end portion of the left and right idler shaft 82 via the belt transmission type first reduction mechanism 81. The two-stage reduction type is configured to transmit the reduced speed from the left end portion to the left end portion of the first screw shaft 59 and the left end portion of the second screw shaft 61 via a belt transmission type second reduction mechanism 83. Further, the rotational power of the second screw shaft 61 is decelerated and transmitted to the swing shaft 85 of the swing sorting means 20 via a belt-transmitting third transmission mechanism 84.

つまり、作業用の伝動手段Bでは、エンジン72からの動力を伝達する唐箕軸51の右端部において高速伝動系Hと低速伝動系Lとに分岐することにより、唐箕軸51の左端部において高速伝動系Hと低速伝動系Lとに分岐する場合に比較して唐箕軸51に掛かる負荷を軽減することができる。   In other words, in the working transmission means B, the high speed transmission system H and the low speed transmission system L are branched at the right end portion of the red shaft 51 that transmits power from the engine 72, so that the high speed transmission is performed at the left end portion of the red shaft 51. Compared with the case of branching to the system H and the low-speed transmission system L, the load applied to the tang shaft 51 can be reduced.

そして、唐箕21、副唐箕22、及び2番唐箕23を高速回転駆動させることができ、これにより、これらの各唐箕21〜23から強い選別風を発生させることができ、結果、風力選別による選別精度の向上を図ることができる。又、チョッパ66も高速回転駆動させることができ、結果、チョッパ66として高い細断性能を確保することができる。   Then, the tang 21, the second tang 22, and the second tang 23 can be driven to rotate at a high speed, thereby generating a strong sorting wind from each of these tangs 21 to 23, and as a result, sorting by wind sorting. The accuracy can be improved. Further, the chopper 66 can also be driven to rotate at a high speed, and as a result, the chopper 66 can ensure high shredding performance.

一方、1番搬送スクリュ60及び2番搬送スクリュ62を、それらのスクリュによる穀粒の損傷が生じ難い低速で駆動することができ、結果、1番搬送スクリュ60及び2番搬送スクリュ62による搬送で穀粒が損傷することに起因した穀粒品質の低下を防止することができる。又、揺動選別手段20を低速で揺動駆動することができ、これにより、揺動選別手段20の高速揺動駆動で穀粒が飛び跳ねることに起因した穀粒回収効率の低下や3番ロスの発生を防止することができる。   On the other hand, the 1st conveyance screw 60 and the 2nd conveyance screw 62 can be driven at a low speed at which grain damage caused by those screws hardly occurs. As a result, the conveyance by the 1st conveyance screw 60 and the 2nd conveyance screw 62 is possible. It is possible to prevent the grain quality from being deteriorated due to the damage of the grain. Further, the swing sorting means 20 can be driven to swing at a low speed, thereby reducing the grain recovery efficiency and the third loss due to the grain jumping by the high speed swing drive of the swing sorting means 20. Can be prevented.

しかも、低速伝動系Lを2段減速式に構成することにより、第1減速機構81及び第2減速機構83などでの変速比を小さくすることができ、第1減速機構81及び第2減速機構83などに備える各プーリ81A,81B,83A〜83Cとして小径のものを採用することができる。これにより、各プーリ81A,81B,83A〜83Cなどの他物との干渉を容易に回避することができ、唐箕軸51から各搬送スクリュ60,62などへの減速伝動が行い易くなる。その結果、作業用の伝動手段Bの組み付け性やメンテナンス性を向上させることができる。   In addition, by configuring the low-speed transmission system L in a two-stage reduction type, the gear ratio in the first reduction mechanism 81 and the second reduction mechanism 83 can be reduced, and the first reduction mechanism 81 and the second reduction mechanism. As the pulleys 81A, 81B, 83A to 83C provided in the 83 or the like, those having a small diameter can be adopted. Thereby, interference with other objects such as the pulleys 81A, 81B, 83A to 83C can be easily avoided, and the speed reduction transmission from the Karatsu shaft 51 to the conveying screws 60, 62, etc. is facilitated. As a result, the assembling property and maintenance property of the working transmission means B can be improved.

作業用の伝動手段Bには、エンジン72からの動力を扱胴軸18に伝達する扱胴伝動系L1と刈取搬送装置2の入力軸であるフィーダ駆動軸14に伝達する刈取搬送伝動系L2とを並列に備えている。   The working transmission means B includes a handling cylinder transmission system L1 that transmits power from the engine 72 to the handling cylinder shaft 18, and a cutting and conveying transmission system L2 that transmits to the feeder drive shaft 14 that is an input shaft of the cutting and conveying apparatus 2.

It is comprised so that it may do. The transmission mechanism 90 for cutting and conveying employs a belt tension clutch that enables intermittent transmission from the idler shaft 82 to the feeder drive shaft 14.

フィーダ駆動軸14に伝達した動力は、チェーン式の第1伝動機構91を介して左右向きの第1中継軸92に伝達し、第1中継軸92から連係機構93を介して切断機構10に伝達し、かつ、第1中継軸92からチェーン式の第2伝動機構94を介して左右向きのオーガ軸95に伝達し、オーガ軸95からチェーン式の第3伝動機構96を介して左右向きの第2中継軸97に伝達し、第2中継軸97からベルト伝動式の第4伝動機構98を介して左右向きのリール軸99に伝達するように構成してある。   The power transmitted to the feeder drive shaft 14 is transmitted to the first relay shaft 92 facing left and right via the chain-type first transmission mechanism 91, and is transmitted from the first relay shaft 92 to the cutting mechanism 10 via the linkage mechanism 93. In addition, the first relay shaft 92 is transmitted to the left-right auger shaft 95 via the chain-type second transmission mechanism 94, and the left-right direction first transmission is performed from the auger shaft 95 via the chain-type third transmission mechanism 96.

It is. The reverse rotation transmission mechanism 101 employs a belt tension clutch that enables intermittent transmission from the reverse rotation shaft 100 to the feeder drive shaft 14.

つまり、収穫作業時には、刈り取り搬送用の伝動機構90を伝動状態とし、逆回転用の伝動機構101を遮断状態とすることにより、刈取搬送装置2を正回転駆動することができ、穀稈を刈り取り搬送することができる。又、刈取搬送装置2において詰まりが発生した場合には、刈り取り搬送用の伝動機構90を遮断状態に切り換え、逆回転用の伝動機構101を伝動状態に切り換えることにより、刈取搬送装置2を逆回転駆動することができ、刈取搬送装置2に詰まった穀稈を簡単に取り除くことができる。   That is, during the harvesting operation, the mowing and conveying mechanism 90 is set in the transmission state, and the reverse rotation transmission mechanism 101 is set in the shut-off state, so that the mowing and conveying device 2 can be driven to rotate forward, and the cereals are harvested. Can be transported. Further, when clogging occurs in the cutting and conveying apparatus 2, the cutting and conveying apparatus 2 is rotated in reverse by switching the transmission mechanism 90 for cutting and conveying to the shut-off state and switching the transmission mechanism 101 for reverse rotation to the transmitting state. It is possible to drive, and the cereals jammed in the cutting and conveying device 2 can be easily removed.

図4、図5及び図7〜9に示すように、扱胴伝動系L1の伝動軸88は、前述したように脱穀フレーム15における上側フレーム部15Aの前端上部に連結した伝動ケース87の左半部に装備してある。フィーダ駆動軸14は、脱穀フレーム15における上側フレーム部15Aの前端下部に左右一対の軸受部材102を介して連結してある。アイドラ軸82は、脱穀装置3における刈取搬送装置2との接続端である前端の外側で、唐箕軸51と副唐箕軸53との間における唐箕軸51よりも副唐箕軸寄りの位置に位置するように、脱穀フレーム15における下側フレーム部15Bの前端上部に左右一対の軸受部材103を介して連結してある。   As shown in FIGS. 4, 5, and 7 to 9, the transmission shaft 88 of the barrel transmission system L <b> 1 is, as described above, the left half of the transmission case 87 connected to the upper front end of the upper frame portion 15 </ b> A in the threshing frame 15. Equipped to the department. The feeder drive shaft 14 is connected to the lower part of the front end of the upper frame portion 15 </ b> A in the threshing frame 15 via a pair of left and right bearing members 102. The idler shaft 82 is located outside the front end, which is the connecting end of the threshing device 3 with the cutting and conveying device 2, at a position closer to the sub-tang shaft than the tang shaft 51 and the sub-pin shaft 53. Thus, it connects with the front-end upper part of the lower frame part 15B in the threshing frame 15 via a pair of left and right bearing members 103.

つまり、扱胴用の入力軸である伝動軸88と刈取搬送装置2の入力軸であるフィーダ駆動軸14とアイドラ軸82とが、その順で脱穀装置3の上部から下部に向けて、アイドラ軸82を伝動軸88及びフィーダ駆動軸14に近づけた状態で、かつ、脱穀装置3の前端に略沿った状態で上下方向に並ぶように配備してある。これにより、アイドラ軸82と伝動軸88とを連動連結する扱胴用の伝動機構86、及び、アイドラ軸82とフィーダ駆動軸14とを連動連結する刈り取り搬送用の伝動機構90を、刈取搬送装置2と脱穀装置3との接続箇所に、前後幅の狭い上下向きでその上下長さを極力短くした状態でコンパクトに配備することができる。   That is, the transmission shaft 88 that is an input shaft for the handling cylinder, the feeder drive shaft 14 that is the input shaft of the cutting and conveying device 2, and the idler shaft 82 are arranged in this order from the upper portion of the threshing device 3 to the lower portion. 82 is arranged so as to be lined up and down in a state of being close to the transmission shaft 88 and the feeder drive shaft 14 and substantially along the front end of the threshing device 3. As a result, the transmission mechanism 86 for the handling cylinder that interlocks and connects the idler shaft 82 and the transmission shaft 88 and the transmission mechanism 90 for cutting and transporting that interlocks and connects the idler shaft 82 and the feeder drive shaft 14 are obtained by the cutting and transporting device. 2 and the threshing device 3 can be compactly deployed in a state where the vertical length is narrow and the vertical length is as short as possible.

図4、図5及び図8に示すように、扱胴用の伝動機構86は、大小一対の伝動回転体86A,86Bとして小径の第1プーリ86Aと大径の第2プーリ86Bとを備え、それらのプーリ86A,86Bを伝動ベルト86Cにより巻き掛け連動するベルト伝動式に構成してある。第1プーリ86Aは、アイドラ軸82の左端部にアイドラ軸82と一体回転するように外嵌したボス部86Aaと、このボス部86Aaと一体回転するようにボス部86Aaに左外側からボルト連結する小径の外周部86Abとから構成してある。第2プーリ86Bは、伝動軸88の左端部に伝動軸88と一体回転するように外嵌したボス部86Baと、このボス部86Baと一体回転するようにボス部86Baに左外側からボルト連結する大径の外周部86Bbとから構成してある。各ボス部86Aa,86Ba及び各外周部86Ab,86Bbは、各ボス部86Aa,86Baに対する各外周部86Ab,86Bbの付け替えが可能となるように、各ボス部86Aa,86Ba及び各外周部86Ab,86Bbの嵌合径及び連結箇所などが一致するように構成してある。   As shown in FIGS. 4, 5, and 8, the transmission mechanism 86 for the handling cylinder includes a first pulley 86 </ b> A having a small diameter and a second pulley 86 </ b> B having a large diameter as a pair of large and small transmission rotating bodies 86 </ b> A and 86 </ b> B. These pulleys 86A and 86B are configured in a belt transmission type in which the pulleys 86A and 86B are wound around and interlocked with a transmission belt 86C. The first pulley 86A is connected to the left end portion of the idler shaft 82 by a boss portion 86Aa externally fitted so as to rotate integrally with the idler shaft 82, and is bolted to the boss portion 86Aa from the left outer side so as to rotate integrally with the boss portion 86Aa. The outer peripheral portion 86Ab has a small diameter.

The outer peripheral portion 86Bb has a large diameter. The boss portions 86Aa, 86Ba and the outer peripheral portions 86Ab, 86Bb are boss portions 86Aa, 86Ba and outer peripheral portions 86Ab, 86Bb so that the outer peripheral portions 86Ab, 86Bb can be replaced with the boss portions 86Aa, 86Ba. The fitting diameter and the connecting location are the same.

この構成により、扱胴用の伝動機構86は、各ボス部86Aa,86Baに対する各外周部86Ab,86Bbの付け替えで、扱胴19に対する伝動状態を、アイドラ軸82と一体回転するボス部86Aaに小径の外周部86Abをボルト連結し、かつ、伝動軸88と一体回転するボス部86Baに大径の外周部86Bbをボルト連結した大豆用の低速伝動状態と、アイドラ軸82と一体回転するボス部86Aaに大径の外周部86Bbをボルト連結し、かつ、伝動軸88と一体回転するボス部86Baに小径の外周部86Abをボルト連結した稲麦用の高速伝動状態とに切り換え可能に構成してある。   With this configuration, the transmission mechanism 86 for the handling cylinder has a small diameter in the boss portion 86Aa that rotates integrally with the idler shaft 82 by changing the outer peripheral portions 86Ab and 86Bb to the boss portions 86Aa and 86Ba. Low-speed transmission state for soybean, in which a large-diameter outer peripheral portion 86Bb is bolted to a boss portion 86Ba rotating integrally with the transmission shaft 88, and a boss portion 86Aa rotating integrally with the idler shaft 82 A large-diameter outer peripheral portion 86Bb is connected to a bolt, and a high-speed transmission state for rice wheat in which a small-diameter outer peripheral portion 86Ab is connected to a boss portion 86Ba rotating integrally with the transmission shaft 88 is configured to be switchable. .

図4、図5、図7及び図8に示すように、フィーダ駆動軸14、アイドラ軸82、及び伝動軸88は、それぞれ、それらの各左端部が走行車体1の左側端に位置するように左外方に向けて延出させてある。アイドラ軸82の左端部には、刈取搬送伝動系L2での伝動方向最上手側の伝動回転体である刈り取り搬送用の伝動機構90の出力プーリ90Aをキー連結でアイドラ軸82と一体回転するように外嵌してある。出力プーリ90Aの右端部には第2減速機構83の出力プーリ83Aを一体形成してある。出力プーリ90Aの左端部には第1プーリ86Aのボス部86Aaを一体形成してある。   As shown in FIGS. 4, 5, 7, and 8, the feeder drive shaft 14, the idler shaft 82, and the transmission shaft 88 have their left end portions positioned on the left end of the traveling vehicle body 1. It extends to the left outward. At the left end of the idler shaft 82, an output pulley 90A of a cutting and conveying transmission mechanism 90, which is a transmission rotating body on the uppermost side in the transmission direction of the cutting and conveying transmission system L2, is rotated integrally with the idler shaft 82 by key connection. It is fitted outside. An output pulley 83A of the second reduction mechanism 83 is integrally formed at the right end portion of the output pulley 90A. A boss portion 86Aa of the first pulley 86A is integrally formed with the left end portion of the output pulley 90A.

図1及び図2に示すように、脱穀装置3の左側部には、脱穀装置3の左外側前端部に配備した扱胴用の伝動機構86及び刈り取り搬送用の伝動機構90などを左外側から覆う第1カバー104と第2カバー105、脱穀装置3の左外側下部に配備した第1伝動機構78、第2伝動機構80、第2減速機構83、及び第3伝動機構84などを第2カバー105とともに左外側から覆う第3カバー106を着脱可能に装備し、かつ、脱穀部3Aの左側部を左外側から覆う第4カバー107をその後端部に備えた縦軸芯を支点にした開閉揺動操作が可能となるように装備してある。   As shown in FIGS. 1 and 2, on the left side of the threshing device 3, a transmission mechanism 86 for a handling cylinder and a transmission mechanism 90 for harvesting and conveying provided at the left outer front end of the threshing device 3 are provided from the left outer side. The first cover 104 and the second cover 105 that cover the first transmission mechanism 78, the second transmission mechanism 80, the second reduction mechanism 83, the third transmission mechanism 84, and the like that are disposed in the lower left lower portion of the threshing device 3 are covered with the second cover. A third cover 106 that is detachably mounted along with 105 from the left outer side, and is provided with a fourth cover 107 that covers the left side of the threshing part 3A from the left outer side. It is equipped to enable dynamic operation.

上記の構成から、作業用の伝動手段Bは、脱穀装置3の左側部から第1カバー104と第2カバー105とを取り外して、走行車体1の左側端部に位置する扱胴用の伝動機構86における各ボス部86Aa,86Baに対する各外周部86Ab,86Bbの付け替えを行うことにより、扱胴19に対する伝動状態を稲麦用の高速伝動状態と大豆用の低速伝動状態とに簡単に切り換えることができ、その結果、損傷し難い稲や麦などを収穫する場合には、扱胴19に対する伝動状態を稲麦用の高速伝動状態に切り換えることによって処理能力の向上を図ることができ、損傷し易い大豆などを収穫する場合には、扱胴19に対する伝動状態を大豆用の低速伝動状態に切り換えることによって扱き処理時の損傷による品質の低下を防止することができる。   From the above configuration, the working transmission means B removes the first cover 104 and the second cover 105 from the left side portion of the threshing device 3, and the transmission mechanism for the handling cylinder located at the left end portion of the traveling vehicle body 1. By changing the outer peripheral portions 86Ab and 86Bb to the boss portions 86Aa and 86Ba in 86, the transmission state for the handling drum 19 can be easily switched between the high-speed transmission state for rice and the low-speed transmission state for soybeans. As a result, when harvesting difficult-to-damage rice, wheat, etc., the processing capacity can be improved by switching the transmission state for the handling drum 19 to the high-speed transmission state for rice wheat, which is easily damaged. When harvesting soybeans and the like, the deterioration of quality due to damage during handling can be prevented by switching the transmission state for the barrel 19 to the low-speed transmission state for soybeans. That.

そして、扱胴19に対する伝動状態の切り換えにかかわらず、刈取搬送装置2を正回転駆動する際の駆動速度、並びに、揺動選別手段20、各唐箕21〜23、各搬送スクリュ60,62,65、及びチョッパ66の各駆動速度を一定に維持することができ、これにより、扱胴19に対する伝動状態の切り換えに起因した刈取搬送装置2での刈取搬送性能の低下、選別部3Bでの選別性能や選別効率の低下、各搬送スクリュ60,62,65の搬送性能の低下、及び、チョッパ66の細断性能の低下、などを防止することができる。   Then, regardless of the switching of the transmission state with respect to the handling cylinder 19, the driving speed when the cutting and conveying apparatus 2 is driven to rotate in the forward direction, the swing selecting means 20, the tangs 21 to 23, and the conveying screws 60, 62, and 65. , And the drive speed of the chopper 66 can be kept constant, thereby reducing the cutting and conveying performance of the cutting and conveying device 2 due to the switching of the transmission state with respect to the handling cylinder 19, and the selecting performance of the selecting unit 3B. In addition, it is possible to prevent a decrease in sorting efficiency, a decrease in the transport performance of the transport screws 60, 62, 65, a decrease in the shredding performance of the chopper 66, and the like.

尚、作業用の伝動手段Bにおいては、上記の構成に代えて例えば以下のように構成することも可能である。
〔1〕高速伝動系Hを、唐箕軸51の回転動力を、唐箕軸51の伝動方向上手側の端部である右端部から副唐箕軸53の右端部と2番唐箕軸57の右端部とチョッパ軸69の右端部とに増速伝達するように構成する。

〔5〕高速伝動系Hの第1伝動機構78と第2伝動機構80、及び、低速伝動系Lの第1減速機構81と第2減速機構83などにチェーン伝動式のものを採用する。あるいは、低速伝動系Lの第1減速機構81にギア伝動式のものを採用する。
〔6〕扱胴用の伝動機構86及び刈り取り搬送用の伝動機構90としてチェーン伝動式のもの又はギヤ伝動式のものを採用する。
〔7〕扱胴用の伝動機構86を、この伝動機構86を介して連動連結する伝動方向下手側の伝動軸(アイドラ軸82又は唐箕軸51)と伝動方向下手側の伝動軸88とに対する大小一対の伝動回転体86A,86B(ボス部86Aa,86Baと外周部86Ab,86Bbとを一体形成したもの)そのものの付け替えで扱胴19に対する伝動を高低2段に切り換えるように構成する。又は、扱胴用の伝動機構86を介して連動連結する伝動方向下手側の伝動軸(アイドラ軸82又は唐箕軸51)と伝動方向下手側の伝動軸88とに対するコンバインに付属した低速伝動専用の一対の伝動回転体(ボス部と外周部とを一体形成したもの)と高速伝動専用の一対の伝動回転体(ボス部と外周部とを一体形成したもの)との交換で扱胴19に対する伝動を高低2段に切り換えるように構成する。あるいは、扱胴用の伝動機構86を介して連動連結する伝動方向下手側の伝動軸(アイドラ軸82又は唐箕軸51)と伝動方向下手側の伝動軸88とのそれぞれに高低伝動兼用に構成した伝動回転体のボス部を一体回転するように外嵌し、これらの各ボス部に対するコンバインに付属した低速伝動専用の一対の伝動回転体の外周部と高速伝動専用の一対の伝動回転体の外周部との交換で扱胴19に対する伝動を高低2段に切り換えるように構成する。
〔8〕逆回転動力取り出し用のベベルギア89A、逆回転軸100、及び、逆回転用の伝動機構101を装備しないことで、刈取搬送装置2の逆回転駆動を行えないように構成する。
The working transmission means B can be configured as follows, for example, instead of the above configuration.
[1] The high-speed transmission system H is driven by rotating the rotary shaft 51 from the right end, which is the upper end of the transmission direction of the rotary shaft 51, to the right end of the auxiliary rotary shaft 53 and the right end of the second rotary shaft 57. The speed increasing transmission is made to the right end portion of the chopper shaft 69.
[2] The low-speed transmission system L is driven by rotating the rotary shaft 51 with the right end of the first screw shaft 59 and the right end of the second screw shaft 61 from the right end, which is the upper end of the transmission shaft 51 in the transmission direction. And a speed reduction transmission to the right end of the swing shaft 85.
[3] The handling cylinder transmission system L <b> 1 is configured to be transmitted to the handling cylinder 19 from the right end or left end of the red collar shaft 51 or the right end of the idler shaft 82.
[4] The cutting and conveying transmission system L2 is configured to be transmitted to the cutting and conveying apparatus 2 from the right end or the left end of the rod shaft 51 or the right end of the idler shaft 82.
[5] The first transmission mechanism 78 and the second transmission mechanism 80 of the high-speed transmission system H, the first reduction mechanism 81 and the second reduction mechanism 83 of the low-speed transmission system L, and the like are employed. Alternatively, a gear transmission type is used for the first reduction mechanism 81 of the low-speed transmission system L.
[6] A chain transmission type or a gear transmission type is adopted as the transmission mechanism 86 for the handling cylinder and the transmission mechanism 90 for the cutting and conveying.
[7] Large and small with respect to the transmission shaft on the lower side in the transmission direction (the idler shaft 82 or the Karatsu shaft 51) and the transmission shaft 88 on the lower side in the transmission direction, in which the transmission mechanism 86 for the barrel is linked and connected via the transmission mechanism 86. By replacing the pair of transmission rotating bodies 86A and 86B (the boss portions 86Aa and 86Ba and the outer peripheral portions 86Ab and 86Bb are integrally formed), the transmission with respect to the handling cylinder 19 is switched between two levels. Alternatively, a dedicated low-speed transmission attached to the combine for the transmission shaft on the lower side in the transmission direction (the idler shaft 82 or the Karatsu shaft 51) and the transmission shaft 88 on the lower side in the transmission direction that are linked and connected via the transmission mechanism 86 for the barrel. Transmission to the handling cylinder 19 by exchanging a pair of transmission rotators (integrated boss and outer periphery) and a pair of transmission rotators dedicated to high speed transmission (integrated boss and outer periphery) Is configured to switch between two levels of high and low. Alternatively, the transmission shaft on the lower side in the transmission direction (the idler shaft 82 or the Karatsu shaft 51) and the transmission shaft 88 on the lower side in the transmission direction that are linked and connected via the transmission mechanism 86 for the barrel are configured to be used for both high and low transmission. The outer periphery of a pair of transmission rotors dedicated to low-speed transmission and the outer periphery of a pair of transmission rotors dedicated to high-speed transmission are fitted to the bosses of the transmission rotor so as to rotate integrally. The transmission with respect to the handling cylinder 19 is configured to be switched between two stages of high and low by exchanging with the part.
[8] Since the reverse rotation power take-out bevel gear 89A, the reverse rotation shaft 100, and the reverse rotation transmission mechanism 101 are not provided, the cutting and conveying device 2 is configured not to be driven in reverse rotation.

図1、図4及び図5に示すように、車体フレーム5における脱穀装置3の直前箇所には、アイドラ軸82の下方空間を利用して作動油タンク108を配備してある。   As shown in FIGS. 1, 4, and 5, a hydraulic oil tank 108 is disposed in the body frame 5 immediately before the threshing device 3 by using a space below the idler shaft 82.

図3に示すように、揺動選別手段20は、その前端上部に配備する粗選別用のグレンパン45の前後長さを短くして前方への延出長さを短くすることで、その前端の前方への揺動限界位置が前後方向で受網16の前端(扱胴19の扱き処理部34の前端)と一致(略一致でも可)するように構成してある。又、受網16の前端を支持する支持部材に利用する穀稈案内板29の後端部と揺動選別手段20の前端とにわたって揺動選別手段20の前方への処理物の漏出を防止する漏出防止手段109を装備してある。漏出防止手段109は、穀稈案内板29の後端部から下方に垂下した上側漏出防止板109Aと、シーブケース44の前端に立設した下側漏出防止板109Bとから構成してある。各漏出防止板109A,109Bには帆布やゴム板などを採用してある。   As shown in FIG. 3, the swing sorting means 20 shortens the front and rear lengths of the rough sorting grain pan 45 disposed on the front end upper portion and shortens the front extension length, thereby reducing the front end. The forward swing limit position is configured to coincide with (or substantially coincide with) the front end of the receiving net 16 (the front end of the handling section 34 of the handling cylinder 19) in the front-rear direction. In addition, the leakage of the processed material to the front of the swing sorting means 20 is prevented over the rear end portion of the grain guide plate 29 used as a support member for supporting the front end of the receiving net 16 and the front end of the swing sorting means 20. Leakage prevention means 109 is provided. The leakage prevention means 109 is composed of an upper leakage prevention plate 109 </ b> A that hangs downward from the rear end portion of the grain straw guide plate 29 and a lower leakage prevention plate 109 </ b> B that is erected at the front end of the sheave case 44. For each leakage prevention plate 109A, 109B, a canvas or a rubber plate is employed.

この構成から、揺動選別手段20が受網16の前端位置よりも前方に不必要に揺動することを防止することができ、これにより、唐箕21と穀稈案内板29との間における揺動選別手段20の前方に大きい空間を確保することができ、この空間を利用してより大型の副唐箕22を装備することで、大量の処理物に対してより十分な選別風を確保することができる。   With this configuration, it is possible to prevent the rocking sorting means 20 from unnecessarily rocking forward from the front end position of the receiving net 16, and thereby, the rocking between the tang rice bowl 21 and the grain straw guide plate 29. A large space can be secured in front of the dynamic sorting means 20, and by using this space to equip a larger sub-tang 22 to secure a sufficient sorting wind for a large amount of processed material. Can do.

又、揺動選別手段20の前方への揺動限界が受網16の前端位置又は前端位置の近くになるように構成しながらも、受網16の前端部から漏下する処理物を揺動選別手段20に確実に供給することができ、処理物が揺動選別手段20の前方に漏出することに起因した穀粒回収率の低下を防止することができる。   Further, while the swing limiter 20 is configured so that the forward swing limit of the swing sorting means 20 is close to the front end position of the receiving net 16 or near the front end position, the workpiece leaking from the front end of the receiving net 16 is swung. It is possible to reliably supply the sorting means 20, and it is possible to prevent the grain recovery rate from being lowered due to the processed material leaking forward of the swing sorting means 20.

図3に示すように、揺動選別手段20は、その後端であるシーブケース44の後端が受網16の後端よりも後方で扱胴19の後端(扱き処理部34の後端)寄りの位置に位置するようにシーブケース44の後端側を後方に延出させてある。又、2番チャフシーブ50は、その前端がチャフシーブ46の後端と前後方向で一致又は略一致するように前端側を前方に延出し、かつ、その後端側をシーブケース44の後端まで延出してある。   As shown in FIG. 3, in the swing sorting means 20, the rear end of the sheave case 44, which is the rear end, is rearward of the rear end of the receiving net 16 and the rear end of the handling cylinder 19 (rear end of the handling unit 34). The rear end side of the sheave case 44 is extended rearward so as to be located at a close position. The second chaff sheave 50 has a front end that extends forward and a rear end that extends to the rear end of the sheave case 44 so that the front end thereof coincides or substantially coincides with the rear end of the chaff sheave 46. It is.

つまり、揺動選別手段20の後端が受網16の後端よりも扱胴19の後端(扱き処理部34の後端)寄りに位置する状態となるように揺動選別手段20を扱胴19(扱き処理部34)に対して後側寄りに配備した構成となっており、これにより、受網16の後端部から漏下する処理物を揺動選別手段20に確実に供給することができ、処理物が揺動選別手段20の後方に漏出することに起因した穀粒回収率の低下を防止することができる。又、2番チャフシーブ50の処理面積(漏下面積)が大きくなることから2番チャフシーブ50の2番処理物に対する選別処理能力を向上させることができる。   In other words, the swing sorting means 20 is handled so that the rear end of the swing sorting means 20 is positioned closer to the rear end of the handling cylinder 19 (the rear end of the handling section 34) than the rear end of the receiving net 16. It is configured to be arranged closer to the rear side with respect to the barrel 19 (the handling processing unit 34), and thereby, the processed material leaking from the rear end portion of the receiving net 16 is reliably supplied to the swing sorting means 20. It is possible to prevent the grain recovery rate from being lowered due to the leakage of the processed material to the rear of the rocking and sorting means 20. In addition, since the processing area (leakage area) of the second chaff sheave 50 is increased, the sorting processing capacity of the second chaff sheave 50 for the second processed product can be improved.

尚、図3において実線で示す揺動選別手段20の状態(位置)は、揺動選別手段20の前端が前方の揺動限界位置に達している状態であり、図3において仮想線(二点鎖線)で示す揺動選別手段20の後端部の状態(位置)は、揺動選別手段20の後端が後方の揺動限界位置に達している状態である。   The state (position) of the swing sorting means 20 indicated by a solid line in FIG. 3 is a state in which the front end of the swing sorting means 20 has reached the forward swing limit position. The state (position) of the rear end portion of the swing sorting means 20 indicated by a chain line is a state in which the rear end of the swing sorting means 20 has reached the rear swing limit position.

図3及び図6に示すように、後側支持部材31には、その下部から揺動選別手段20の後方に向けて後下がり傾斜姿勢で延出して、排稈口32から流下する脱粒穀稈や長い稈屑などの排出物を揺動選別手段20の後方に配備したチョッパ66に案内する排稈案内板110を装備してある。これにより、受網16から漏下せずに排稈口32から流下する脱粒穀稈や長い稈屑などの排出物が2番チャフシーブ50に供給されることに起因した2番チャフシーブ50での選別効率や選別精度の低下などを防止することができる。   As shown in FIGS. 3 and 6, the rear support member 31 extends from the lower part toward the rear of the swing sorting means 20 in a rearwardly inclined posture and flows down from the discharge port 32. In addition, a waste guide plate 110 is provided for guiding a discharged material such as long waste dust to a chopper 66 disposed behind the swing sorting means 20. As a result, the sorting at the second chaff sheave 50 caused by the discharge of the cereal cereals and the long swarf flowing down from the discharge port 32 without leaking from the receiving net 16 is supplied to the second chaff sheave 50. It is possible to prevent a decrease in efficiency and sorting accuracy.

図3に示すように、チャフシーブ46は、扱胴19の扱き処理部34の前後中間部位に配備した仕切板39からチャフシーブ46の前端までの前後長さLaが仕切板39からチャフシーブ46の後端までの前後長さLbよりも長くなるように仕切板39に対して前側に偏倚した状態で配備してある。つまり、この揺動選別手段20では、チャフシーブ46における仕切板39よりも前側の処理面積(漏下面積)を大きく確保するようにしてあり、これにより、仕切板39によって扱き処理後の処理物の多くが揺動選別手段20の前部側に漏下するようになったとしても、その処理物をチャフシーブ46によって効率良く粗選別することができる。   As shown in FIG. 3, the chaff sheave 46 has a longitudinal length La from the partition plate 39 to the front end of the chaff sheave 46 arranged at the front and rear intermediate portion of the handling section 34 of the handling cylinder 19. It is arranged in a state of being biased forward with respect to the partition plate 39 so as to be longer than the longitudinal length Lb. In other words, the swing sorting means 20 ensures a large processing area (leakage area) on the front side of the partition plate 39 in the chaff sheave 46, so that the processed material after the handling process is performed by the partition plate 39. Even if many of them leak to the front side of the swing sorting means 20, the processed material can be roughly roughly sorted by the chaff sheave 46.

尚、粗選別用のグレンパン45の前後長さは、仕切板39からチャフシーブ46の前端までの前後長さLaと略同じ長さ(又は仕切板39からチャフシーブ46の前端までの前後長さLaよりも短い長さ)に設定してあり、粗選別用のグレンパン45の後端部及びチャフシーブ46の前端部が前端用の支持板37と仕切板39との前後中間部に位置するように構成してある。   The front and rear length of the rough sorting grain pan 45 is substantially the same as the front and rear length La from the partition plate 39 to the front end of the chaff sheave 46 (or the front and rear length La from the partition plate 39 to the front end of the chaff sheave 46). The rear end portion of the rough sorting grain pan 45 and the front end portion of the chaff sheave 46 are positioned at the front and rear intermediate portions of the support plate 37 and the partition plate 39 for the front end. It is.

図4及び図5に示すように、脱穀フレーム15における下側フレーム部15Bの前部には、脱穀部3Aの前部側を支持する左右一対の前側支柱部材111と左右一対の後側支柱部材112とを唐箕ケース52の左右両端部に形成した唐箕用の吸気口52Cを前後から挟むように立設してある。そして、左右同じ側に位置する前側支柱部材111の下部側と後側支柱部材112の下部側とにわたって唐箕軸51の左右の端部を回転可能に支持する前後向きの唐箕支持部材113を唐箕用の吸気口52Cを横断するように架設してある。又、左右同じ側に位置する前側支柱部材111の上部側と後側支柱部材112の上部側とにわたって副唐箕軸53の左右の端部を回転可能に支持する前後向きの副唐箕支持部材114を副唐箕ケース54の左右両端部に形成した副唐箕用の吸気口54Bを横断するように架設してある。   As shown in FIG.4 and FIG.5, in the front part of the lower frame part 15B in the threshing frame 15, a pair of left and right front column members 111 and a pair of left and right rear column members supporting the front side of the threshing unit 3A 112 is erected so as to sandwich the intake port 52C for the red pepper formed at the left and right ends of the red pepper case 52 from the front and rear. Then, a front / rear facing rod support member 113 for rotatably supporting the left and right end portions of the rod shaft 51 across the lower side of the front column member 111 and the lower side of the rear column member 112 located on the same left and right side is used for the rod. It is constructed so as to cross the intake port 52C. Further, a front and rear side auxiliary rod support member 114 for rotatably supporting the left and right end portions of the auxiliary rod shaft 53 across the upper side of the front column member 111 and the upper side of the rear column member 112 located on the same left and right side is provided. The auxiliary tang case 54 is installed so as to traverse the auxiliary tang air inlets 54B formed at both left and right ends of the case.

つまり、脱穀部3Aの前部側を支持するために高い強度を有するように構成した左右一対の前側支柱部材111と左右一対の後側支柱部材112とを利用して唐箕21及び副唐箕22を支持するようにしていることから、支持構造の簡素化を図ることができる。   That is, using the pair of left and right front strut members 111 and the pair of left and right rear strut members 112 configured to have high strength to support the front side of the threshing portion 3A, Since support is made, the support structure can be simplified.

図4に示すように、左右の各副唐箕支持部材114には、副唐箕軸53を挟んだ前後の位置に副唐箕用の補助吸気口114Aを形成してある。これにより、副唐箕用の吸気口54Bを副唐箕支持部材114が横断することによって不足し易くなる副唐箕22に対する吸気量を改善することができ、副唐箕22からの選別風による風力選別を良好に行うことができる。   As shown in FIG. 4, auxiliary intake ports 114 </ b> A for the auxiliary tang are formed in the left and right auxiliary tang support members 114 at positions before and after the auxiliary tang shaft 53. As a result, it is possible to improve the amount of intake air to the auxiliary tang 22 that is likely to be insufficient when the auxiliary tang support member 114 crosses the intake port 54B for the auxiliary tang, so that the wind selection by the selected air from the auxiliary tang 22 is good. Can be done.

図3に示すように、唐箕21は、その唐箕軸51の直上近傍方位置(直上方位置でも可)に揺動選別手段20の前端の前方への揺動限界位置が位置するように配備してある。又、前述したように、揺動選別手段20の前端の前方への揺動限界位置は前後方向で受網16の前端と一致(略一致でも可)させてある。そして、このように揺動選別手段20の前端の前方への揺動限界位置を設定し、かつ、受網16及び唐箕21を配備することにより、唐箕21の前半部の直上方位置に収容空間を形成してあり、この収容空間に、唐箕21の前端と副唐箕22の前端とが前後方向で略一致(一致でも可)させた状態で副唐箕22を配備してある。   As shown in FIG. 3, the red pepper 21 is arranged so that the forward swing limit position of the front end of the swing sorting means 20 is located at a position immediately above the hot shaft 51 (or a position directly above). It is. Further, as described above, the forward swing limit position of the front end of the swing sorting means 20 is aligned with the front end of the receiving net 16 in the front-rear direction (may be substantially matched). In this way, by setting the swing limit position forward of the front end of the swing sorting means 20 and arranging the receiving net 16 and the tang 21, the accommodation space is located immediately above the front half of the tang 21. The auxiliary tang 22 is arranged in this accommodating space in a state where the front end of the tang 21 and the front end of the tang 22 are substantially matched (possibly coincident) in the front-rear direction.

つまり、揺動選別手段20の前端の前方への揺動限界位置と唐箕21の唐箕軸21と受網16の前端とが略鉛直線上(鉛直線上でも可)に並ぶように構成してあり、これにより、揺動選別手段20が受網16の前端位置よりも前方に不必要に揺動することを防止するとともに、唐箕21の前半部の上方で揺動選別手段20の前方に大きい収容空間を確保することができ、この収容空間を利用してより大型の副唐箕22を装備することができ、結果、大量の処理物に対してより十分な選別風を確保することができる。   That is, the swing limit position forward of the front end of the swing sorting means 20, the head shaft 21 of the head 21 and the front end of the receiving net 16 are arranged on a substantially vertical line (or on the vertical line). Accordingly, the swing sorting means 20 is prevented from unnecessarily swinging forward from the front end position of the receiving net 16, and a large accommodation space is provided in front of the swing sorting means 20 above the front half of the tang 21. Can be secured, and a larger sub-tang 22 can be equipped using this accommodation space, and as a result, a more sufficient sorting wind can be secured for a large amount of processed material.

図3に示すように、唐箕21及び副唐箕22は、それらの前端が脱穀フレーム15における上側フレーム部15Aの内部に装備する扱胴19の前端と前後方向で略一致(一致でも可)するように脱穀フレーム15の下側フレーム部15Bに装備してある。これにより、揺動選別手段20の前下方に配備する唐箕21をその前端が扱胴19の前端よりも後方に位置するように後方寄りに配備する場合に比較して、揺動選別手段20の下部に配備するグレンシーブ49の前後長さを長くすることができ、グレンシーブ49の処理面積(漏下面積)を大きく確保できることから、グレンシーブ49での穀粒回収効率の向上を図ることができる。又、副唐箕22を脱穀フレーム15の前端から前方に張り出さない状態でコンパクトに配備することができ、副唐箕22を装備することに起因した脱穀選別構造の大型化を防止することができる。   As shown in FIG. 3, the tangs 21 and the tangs 22 are arranged so that their front ends substantially coincide with the front ends of the handling cylinders 19 provided in the upper frame portion 15 </ b> A of the threshing frame 15 in the front-rear direction. Is mounted on the lower frame portion 15B of the threshing frame 15. Thereby, compared with the case where the Kara 21 arranged at the front lower side of the swing sorting means 20 is placed rearward so that the front end thereof is located behind the front end of the handling cylinder 19, Since the front and rear lengths of the grain sieve 49 arranged at the lower portion can be increased and a large processing area (leakage area) of the grain sieve 49 can be secured, the grain recovery efficiency at the grain sieve 49 can be improved. In addition, the auxiliary tang 22 can be compactly arranged without protruding forward from the front end of the threshing frame 15, and an increase in the size of the threshing sorting structure resulting from the provision of the auxiliary tang 22 can be prevented.

尚、脱穀装置3の脱穀選別構造においては、上記の構成に代えて例えば以下のように構成することも可能である。
〔1〕副唐箕22からの選別風がチャフシーブ46のチャフリップ板46Aの間を積極的に通過するように副唐箕22からの選別風を揺動選別手段20に供給する。

In addition, in the threshing selection structure of the threshing device 3, it can also be configured as follows instead of the above configuration, for example.
[1] The sorting air from the sub-tang 22 is supplied to the oscillating sorting means 20 so that the sorting air from the sub-tan 22 is positively passed between the chaff plates 46A of the chaff sheave 46.
[2] The swing sorting means so that the swing limit position to the rear of the rear end of the swing sorting means 20 coincides or substantially coincides with the rear end of the handling cylinder 19 (the rear end of the handling processing unit 34) in the front-rear direction.
