上記特許文献１記載の構成によれば、扱室内のフィードチェン側に配置された抵抗板と扱胴の間に被処理物を扱室内方へ案内するガイド体やガイド体と扱胴の間に被処理物の搬送に抵抗を与える仕切板を設けている。また、扱室から排塵処理室への連通口には扱胴の搬送方向上手側に被処理物を送塵する逆リード板が設けられ、容易に排塵処理室へ導かれようとする処理物を被処理物の搬送方向上手側に戻す構成が開示されている。
また、上記特許文献２記載の構成によれば、扱室の後板と中後板間に扱胴の扱歯の回転外周に沿ってガイド部材を設け、更に扱室の中後板の外側面には平面視がへの字（Ｌ字）形状の穂先支えガイドを側面視左外側へ向けて上り傾斜に設けた構成が開示されている。 According to the configuration described in Patent Document 1, a guide body that guides an object to be processed toward the inside of the handling chamber between the resistance plate disposed on the feed chain side in the handling chamber and the handling cylinder, or between the guide body and the handling cylinder. A partition plate that provides resistance to the conveyance of the workpiece is provided. The communication port from the handling chamber to the dust disposal chamber is provided with a reverse lead plate that sends the workpiece to the upper side in the transport direction of the barrel, so that it can be easily guided to the dust disposal chamber. The structure which returns a thing to the conveyance direction upper direction side of a to-be-processed object is disclosed.
Moreover, according to the structure of the said patent document 2, a guide member is provided along the rotation outer periphery of the tooth-handling of a handling cylinder between the rear plate and middle rear plate of a handling chamber, and also the outer side surface of the middle rear plate of a handling chamber Discloses a configuration in which a tip support guide having a U-shape (L-shape) in plan view is provided so as to be inclined upward toward the left outer side in a side view.

上記特許文献１記載の構成によれば、ガイド体により扱室内の被処理物を扱室内方に導き、株元にささり込む穀粒を低減し、更にガイド体と仕切板により扱胴の搬送方向下手側に移送される被処理物を制限するので、仕切板後方でのササリ粒の回収が良好となる。また、排塵処理室の連通口の直前に、被処理物の戻し方向（搬送方向上手側）にリード角度を有する逆リード板を設け、容易に排塵処理室へ導かれようとする被処理物を制限している。このように、扱胴の外周を連れ回るササリ粒（正常な穀粒が藁と連れ回ることで藁に刺さって発生する）などの被処理物を扱胴の搬送方向上手側に戻し、四番穀粒のロス低減を図っている。 According to the configuration described in Patent Document 1, the material to be processed in the handling chamber is guided to the inside of the handling chamber by the guide body, and the grains that are crushed into the stock are reduced. Since the object to be processed transferred to the lower side is limited, the recovery of the scorpion grains at the rear of the partition plate is improved. In addition, a reverse lead plate having a lead angle in the return direction of the object to be processed (upper side in the transport direction) is provided immediately before the communication port of the dust disposal chamber, and the object to be treated is easily guided to the dust disposal chamber. Things are restricted. In this way, the processing object such as scorpion grains that rotate around the outer periphery of the handling cylinder (generated by normal grains being stuck in the cocoon along with the cocoon) is returned to the upper side in the conveying direction of the handling cylinder, and the fourth The grain loss is reduced.

また、上記特許文献２記載の構成によれば、上記特許文献１記載の構成と同様に、扱歯の回転外周に沿って設けたガイド部材により扱室内の被処理物を扱室内方に導き、ガイド部材と各扱歯との相互作用により、ササリ粒の除去を良好にしている。また、平面視がへの字形状の穂先支えガイドを側面視左外側に向けて上り傾斜になるように扱室後方側に設けており、すなわち特許文献１記載の逆リード板と同様に、被処理物の戻し方向（搬送方向上手側）にリード角度を設けて配置し、ササリ粒を回収している。 Moreover, according to the structure of the said patent document 2, like the structure of the said patent document 1, it guides the to-be-processed object in a handling chamber to the inside of a handling chamber by the guide member provided along the rotation outer periphery of a tooth-handling, By the interaction between the guide member and each tooth handling, the removal of the scorpion grains is made good. Further, the tip support guide having a U-shape in a plan view is provided on the rear side of the handling chamber so as to be inclined upward toward the left outer side in a side view, that is, in the same manner as the reverse lead plate described in Patent Document 1. A lead angle is provided in the return direction of the processed material (upper side in the conveying direction) to collect the scorpion grains.

このように、従来は扱室内の被処理物を扱室内方に導いたり、扱胴の搬送方向下手側に移送される被処理物を制限することで、穀粒の回収効率を向上させていた。 Thus, conventionally, the collection efficiency of the grain has been improved by guiding the object to be processed in the handling chamber toward the inside of the chamber or limiting the object to be transferred to the lower side in the conveyance direction of the handling cylinder. .

しかし、被処理物量が多い場合など、負荷が大きい条件下では、扱胴の搬送方向下手側に移送される被処理物が制限されて、扱室内に被処理物が溜まり、被処理物の排塵処理室への流れも制限されるという問題がある。また、扱室内に被処理物が溜まることで、扱室内の異音発生の要因ともなっていた。一方で、扱胴の搬送方向下手側に移送される被処理物を制限しないと扱室下方にある扱網から後方側に安易に被処理物が送塵されてしまい、穀粒の回収効率の低下を招く。 However, under heavy load conditions, such as when the amount of workpieces is large, the workpieces that are transferred to the lower side of the handling cylinder in the transport direction are limited, and the workpieces are collected in the handling chamber, and the waste of the workpieces is discharged. There is a problem that the flow to the dust treatment chamber is also restricted. In addition, accumulation of objects to be processed in the handling chamber has been a cause of abnormal noise in the handling chamber. On the other hand, if there is no restriction on the object to be transferred to the lower side in the conveying direction of the handling cylinder, the object to be processed is easily sent to the rear side from the handling net below the handling chamber, and the efficiency of grain recovery is reduced. Incurs a decline.

本発明の課題は、上記問題点を解決することであり、負荷が大きい条件下においても、被処理物を濾過する扱網から後方側に安易に被処理物が送塵されることを防止して、扱網による被処理物のろ過を促進するとともに、被処理物の排塵処理室への流れを制限せず、一層の四番穀粒のロス低減が図れる脱穀装置の提供である。また、負荷が大きい条件下においても、扱室内の異音発生を防止できる脱穀装置の提供である。 An object of the present invention is to solve the above-mentioned problems, and even under heavy load conditions, it is possible to prevent the processed material from being easily sent to the rear side from the handling net for filtering the processed material. In addition, the present invention provides a threshing device that promotes filtration of the object to be processed by the handling net, and does not restrict the flow of the object to be processed into the dust disposal chamber, and can further reduce the fourth grain loss. Moreover, it is provision of the threshing apparatus which can prevent generation | occurrence | production of the noise in a handling chamber also on the conditions with heavy load.

刈取装置６で刈り取った穀稈は刈取装置６に装着された穀稈搬送、調節装置で扱深さが調節され、脱穀装置１５の主脱穀部である扱室６６内に挿入される。扱室６６に軸架された扱胴６９は、その表面に多数の扱歯６９ａが設けられており、図示しない駆動機構により、エンジンからの動力により、図４ないし図５の矢印Ｂ方向に回転する。扱室６６に挿入された穀粒の付いた穀稈は、移動するフィードチェン１４により図４の矢印Ａ方向に移送されながら、矢印Ｂ方向に回転する扱胴６９の扱歯６９ａと扱網７４との相互作用により脱穀される。また、扱網７４のフィードチェン１４側の下部を、前板９７から後方中板９６Ｒにかけて網押さえ７７により支持している。穀稈から分離された被処理物（穀粒や藁くず）は扱網７４を矢印Ｃ１方向（図５）に通過して、揺動棚５１で受け止められる。 The grain husks harvested by the reaping device 6 are adjusted in the handling depth by the cereal conveyance and adjusting device attached to the reaping device 6 and inserted into the handling chamber 66 which is the main threshing portion of the threshing device 15. A handling drum 69 pivoted in the handling chamber 66 has a large number of teeth 69a on its surface, and is rotated in the direction of arrow B in FIGS. To do. Grains with grains inserted in the handling chamber 66 are transferred in the direction of arrow A in FIG. 4 by the moving feed chain 14, and the teeth 69 a and the handling net 74 of the handling drum 69 that rotate in the direction of arrow B are rotated. Is threshed by the interaction. Further, the lower part of the handling net 74 on the feed chain 14 side is supported by a net presser 77 from the front plate 97 to the rear middle plate 96R. The object to be processed (grains and wastes) separated from the cereals passes through the handle net 74 in the direction of arrow C1 (FIG. 5) and is received by the swing shelf 51.

揺動棚５１は、扱室６６の扱網７４の下方に配置した移送棚５２とその後方に配置した上方の第１チャフシーブ５３、第２チャフシーブ５４とその下方の選別網６３と最後端部に配置したストローラック６２などから構成されている。 The swing shelf 51 includes a transfer shelf 52 arranged below the handling net 74 of the handling chamber 66, an upper first chaff sheave 53 and a second chaff sheave 54 arranged behind it, and a sorting net 63 below and a rearmost end. It is comprised from the stroller 62 etc. which were arrange | positioned.

第１チャフシーブ５３と第２チャフシーブ５４は、揺動しながら各シーブ間から被処理物を漏下させ、唐箕７９からの送風により風力選別する点で共通しているが、被処理物の搬送方向前方側の第１チャフシーブ５３の方が後方側にある第２チャフシーブ５４に比べて各シーブの大きさが小さく、各シーブ間の距離が多少狭い構成である。被処理物の搬送方向前方側では、被処理物中における単粒の含有率が高く、藁屑の漏下を抑えながら単粒だけを漏下させ、藁屑をより後方へ移送するために、このような構成としている。 The first chaff sheave 53 and the second chaff sheave 54 are common in that the workpiece is leaked from between the sheaves while swinging and the wind is selected by blowing air from the tang 79, but the conveying direction of the workpiece The first chaff sheave 53 on the front side is smaller in size than the second chaff sheave 54 on the rear side, and the distance between the sheaves is somewhat narrow. On the front side in the transport direction of the workpiece, the single grain content in the workpiece is high, so that only the single grain is leaked while suppressing the leakage of the sawdust, and the sawdust is transferred to the rear. Such a configuration is adopted.

また、第１チャフシーブ５３の上方に、揺動棚５１上の被処理物を拡散させる拡散ガイド８８を、被処理物の搬送方向に向かって拡散ガイド８８の前端が前記移送棚５２の上方に位置するように設けている。

Further, the communication port 101 may be provided on the near side in the conveyance direction of the object to be processed, or a plurality thereof may be provided. Further, as shown in FIGS. 5 and 6, a simple structure can be obtained by providing it on the handling cylinder cover 102 above the handling cylinder 69.

前述のように、従来は、扱室６６から排塵処理室６８への連通口には扱胴６９の搬送方向上手側に被処理物の戻し方向（搬送方向上手側）にリード角度を設けた逆リード板が設けられ、容易に排塵処理室６８へ導かれようとする処理物を被処理物の搬送方向上手側に戻していた。しかし、被処理物量が多い場合などの負荷が大きい条件下では、扱胴６９の搬送方向下手側に移送される被処理物が制限されて、扱室６６内に被処理物が溜まり、被処理物の排塵処理室６８への流れも制限されるという問題があった。すなわち被処理物の排塵処理室６８への流れが考慮されていなかった。 As described above, conventionally, the communication port from the handling chamber 66 to the dust disposal chamber 68 is provided with a lead angle in the return direction of the workpiece (upper side in the transport direction) on the upper side in the transport direction of the handling cylinder 69. A reverse lead plate was provided, and the processed material that was easily guided to the dust removal processing chamber 68 was returned to the upper side in the conveyance direction of the workpiece. However, under a heavy load condition such as when the amount of the object to be processed is large, the object to be processed transferred to the lower side in the conveying direction of the handling cylinder 69 is limited, and the object to be processed accumulates in the handling chamber 66, and the object to be processed There is a problem that the flow of the object to the dust disposal chamber 68 is also limited. That is, the flow of the object to be treated to the dust disposal chamber 68 has not been considered.

また、扱室６６内に被処理物が溜まることで、扱室６６内の異音発生の要因ともなっていた。一方で、扱胴６９の搬送方向下手側に移送される被処理物を制限しないと扱室６６下方にある扱網７４から後方側に安易に被処理物が送塵されてしまい、穀粒の回収効率の低下を招くこともある。 In addition, accumulation of objects to be processed in the handling chamber 66 is a cause of abnormal noise in the handling chamber 66. On the other hand, if the object to be transferred to the lower side in the conveying direction of the handling cylinder 69 is not restricted, the object to be processed is easily sent to the rear side from the handling net 74 below the handling chamber 66, There may be a decrease in recovery efficiency.

しかし、本構成を採用することにより、抵抗ガイド板（案内板）８４を設けることで、負荷が大きい条件下においても、ある程度被処理物の後方への流れが制限され、被処理物を濾過する扱網７４から後方側に安易に被処理物が送塵されるのを防止して、扱網７４による被処理物のろ過を促進できる。すなわち扱室６６における被処理物の後方への搬送に抵抗を与える抵抗板としての機能を有する。 However, by adopting this configuration, by providing the resistance guide plate (guide plate) 84, the flow to the rear side of the workpiece is limited to some extent even under heavy load conditions, and the workpiece is filtered. It is possible to prevent the workpiece from being easily sent to the rear side from the handling net 74 and to facilitate the filtration of the workpiece by the handling net 74. That is, it has a function as a resistance plate that gives resistance to the rearward transfer of the workpiece in the handling chamber 66.

一方、抵抗ガイド板（案内板）８４は、扱胴６９の軸芯と略直交する方向に平面部を有しており、リード角度をほどんど設けていないことから、リード角度を設けている場合よりも扱室６６内が過負荷となることを防止できる。そして、リード角度を設けている場合よりも被処理物の排塵処理室６８への流れが制限されず、一層の四番穀粒のロス低減が図れる。また、負荷が大きい条件下においても、扱室６６内の異音発生を防止できる。このように、排塵処理室６８へ被処理物を搬送するガイド板としての機能を有する。
すなわち、抵抗ガイド板（案内板）８４は、扱室６６における被処理物の後方への搬送に抵抗を与える抵抗板としての機能と、排塵処理室６８へ被処理物を搬送するガイド板としての機能を適度に併せ持つ。 On the other hand, the resistance guide plate (guide plate) 84 has a flat portion in a direction substantially orthogonal to the axis of the handling cylinder 69 and has almost no lead angle. As a result, the inside of the handling chamber 66 can be prevented from being overloaded. And the flow to the dust disposal chamber 68 of a to-be-processed object is not restrict | limited compared with the case where the lead angle is provided, and the loss reduction of a 4th grain can be aimed at. Further, it is possible to prevent the generation of abnormal noise in the handling chamber 66 even under a heavy load condition. Thus, it has a function as a guide plate for transporting the object to be processed to the dust disposal chamber 68.
That is, the resistance guide plate (guide plate) 84 functions as a resistance plate that gives resistance to the rearward transfer of the object to be processed in the handling chamber 66 and serves as a guide plate for transferring the object to be processed to the dust disposal chamber 68. With moderately combined functions.

そして、連通口１０１よりも後方の扱室６６内に被処理物中のササリ粒などを回収する回収室６６ａを設けると、上記のように抵抗ガイド板（案内板）８４にリード角度を設けている場合よりも扱室６６内が過負荷とならず、後方への搬送が制限されないことから、適度に回収室６６ａにおいてササリ粒を回収することができ、回収効率が向上する。 When the recovery chamber 66a for recovering the scorpion particles in the object to be processed is provided in the handling chamber 66 behind the communication port 101, the lead angle is provided to the resistance guide plate (guide plate) 84 as described above. Since the inside of the handling chamber 66 is not overloaded and the rearward transfer is not restricted as compared with the case where the dust is present, it is possible to appropriately collect the scorpion grains in the recovery chamber 66a, thereby improving the recovery efficiency.

また、案内板８４は連通口１０１の前方中板９６Ｆよりも前側に設けてもよいし、図３及び図４に示すように、前方中板９６Ｆを挟んで前後に複数個設けても良い。すなわち、扱室６６内における扱胴６９の被処理物の搬送方向に互いに位置をずらせて設けても良い。
本構成を採用することにより、案内板８４ａ,８４ｂを扱胴６９における被処理物の搬送経路の前後方向に複数設けて被処理物の移送に抵抗を加えることで、扱網７４における被処理物のろ過を促進でき、選別効率が向上する。また、被処理物の搬送方向の前後に分けて案内板８４ａ,８４ｂを設けることで、一度に連通口１０１付近に穀粒が流入し負荷が増大することなく、扱室６６内の前方（被処理物の搬送方向始端部側）から中間部位においても扱網７４からの濾過が促進されるので、扱室６６内の濾過効率が高まり、三番、四番穀粒の回収ロスの低減効果が高まる。 Further, the guide plate 84 may be provided in front of the front middle plate 96F of the communication port 101, or as shown in FIGS. 3 and 4, a plurality of guide plates 84 may be provided on the front and rear sides of the front middle plate 96F. That is, the positions of the processing cylinders 69 in the handling chamber 66 may be shifted from each other in the conveying direction of the workpiece.
By adopting this configuration, a plurality of guide plates 84a and 84b are provided in the front-rear direction of the conveyance path of the object to be processed in the handling cylinder 69, and resistance is applied to the transfer of the object to be processed. Filtration can be promoted, and the sorting efficiency is improved. Further, by providing the guide plates 84a and 84b separately before and after in the conveyance direction of the object to be processed, the grain flows into the vicinity of the communication port 101 at a time and the load increases without increasing the load. Since the filtration from the handling net 74 is promoted even in the intermediate part from the conveyance direction starting end side of the processed material, the filtration efficiency in the handling chamber 66 is increased, and the effect of reducing the recovery loss of the third and fourth grains is improved. Rise.

また、図６に示すように、案内板８４の下端部が扱胴６９回転時の扱歯６９ａの先端軌跡Ｕとほぼ同じ高さ位置になるように案内板８４を設置してもよい。
すなわち、扱胴６９における被処理物の搬送方向から見て案内板８４の下端部と扱胴６９回転時の扱歯６９ａの先端軌跡が重なる程度まで案内板８４の下端部を下方に延ばしても良い。 In addition, as shown in FIG. 6, the guide plate 84 may be installed so that the lower end portion of the guide plate 84 is positioned at substantially the same height as the tip locus U of the teeth 69 a when the handle 69 rotates.
That is, even if the lower end portion of the guide plate 84 is extended downward until the lower end portion of the guide plate 84 overlaps the tip locus of the tooth 69a when the handle barrel 69 rotates as viewed from the conveying direction of the workpiece in the handle barrel 69. good.

案内板８４の前端部と後端部の前後位置を変えている（リード角度も持たせている）場合は、案内板８４の平面部が扱胴６９の軸芯に対し斜めに交わるため、案内板８４の下端部を扱歯６９ａの先端軌跡Ｕとほぼ同じ高さ位置になるように設置すると、案内板８４の下端部が扱胴６９の前後の扱歯６９ａ,６９ａに当たってしまう。したがって、このように設置することはできない。 When the front and rear positions of the front end portion and the rear end portion of the guide plate 84 are changed (the lead angle is also given), the plane portion of the guide plate 84 intersects with the axis of the handling cylinder 69 at an angle. If the lower end portion of the plate 84 is installed so as to be at substantially the same height as the tip locus U of the tooth handle 69 a, the lower end portion of the guide plate 84 hits the tooth handles 69 a and 69 a before and after the handle barrel 69. Therefore, it cannot be installed in this way.

しかし、本実施形態によれば、案内板８４は扱胴６９の軸芯に対し略直交する方向に平面部を設けているので、扱歯６９ａの先端軌跡と同じ高さ程度まで下端部を延ばしても前後の扱歯６９ａ,６９ａ間に案内板８４の平面部が位置し、扱歯６９ａには当たらない。 However, according to the present embodiment, since the guide plate 84 is provided with a flat portion in a direction substantially orthogonal to the axis of the handling drum 69, the lower end is extended to the same height as the tip locus of the tooth handling 69a. However, the flat portion of the guide plate 84 is positioned between the front and rear teeth 69a and 69a and does not hit the teeth 69a.

本構成を採用することにより、案内板８４と扱歯６９ａの相互作用によって被処理物の後方への搬送に抵抗を加える効果が高まるので、フィードチェン１４のスピードが速い大型のコンバインなどでも扱室６６内の処理時間を長く保つことができ、穀粒の単粒化や三番、四番穀粒の回収ロスの低減が可能である。 By adopting this configuration, the effect of adding resistance to the rearward conveyance of the object to be processed is increased by the interaction between the guide plate 84 and the teeth 69a. Therefore, even in a large combine where the speed of the feed chain 14 is fast, etc. The processing time in 66 can be kept long, and the grain loss can be reduced and the recovery loss of the third and fourth grains can be reduced.

更に、図３から図６に示すように、扱室６６内のフィードチェン１４側に設けられた株元側ガイド体８２の内面（扱胴６９側）に、株元側ガイド体８２の長手方向に直交する方向に板状平面部を有し、扱胴６９における搬送方向下手側への被処理物の搬送を制限する株元側仕切板（仕切体）９３を設けても良い。 Further, as shown in FIG. 3 to FIG. 6, the longitudinal direction of the stock-side guide body 82 is formed on the inner surface (hand barrel 69 side) of the stock-side guide body 82 provided on the feed chain 14 side in the handling chamber 66. A stock-side partition plate (partition body) 93 that has a plate-like flat portion in a direction perpendicular to the handle and restricts the conveyance of the object to be processed to the lower side in the conveyance direction in the handling cylinder 69 may be provided.

扱胴カバー１０２内面の案内板８４や上部仕切板８３により後方への搬送に抵抗を与えられた被処理物は扱室６６内に停滞しがちになるが、フィードチェン１４側に設けられた株元側仕切板９３により再度被処理物を搬送穀稈の株元にささり込むことがないように止めて、扱室６６から外部に排出されることを防止できる。 The object to be processed which is given resistance to the rearward conveyance by the guide plate 84 and the upper partition plate 83 on the inner surface of the handling cylinder cover 102 tends to stagnate in the handling chamber 66, but the stock provided on the feed chain 14 side. The original side partition plate 93 can prevent the object to be processed again from entering the stock of the transported cereal and prevent it from being discharged from the handling chamber 66 to the outside.

また、図３に示すように、扱胴６９における被処理物の搬送方向に向かって、案内板８４と株元側仕切板９３の前後位置をほぼ同じにしても良い。案内板８４及び株元側仕切板９３によって、搬送方向に向かって左右方向から被処理物の搬送経路が塞がれるため、より扱室６６後方への被処理物の送塵を止める効果が高まり、三番穀粒、四番穀粒の回収ロスも低減する。 As shown in FIG. 3, the front and rear positions of the guide plate 84 and the stockholder side partition plate 93 may be made substantially the same in the direction of conveyance of the object to be processed in the handling drum 69. Since the guide plate 84 and the stockholder side partition plate 93 block the transfer path of the object to be processed from the left and right directions in the transfer direction, the effect of stopping the dust from being supplied further to the rear of the handling chamber 66 is enhanced. The recovery loss of No. 3 and No. 4 grains is also reduced.

更に、扱室６６内の後方側（回収室６６ａ側）であってフィードチェン１４側に後方ガイド板１０５を設けても良い。図７及び図８に示すように、後方ガイド板１０５を網押さえ７７の後方であって扱室６６内のフィードチェン１４側から選別室５０内の揺動棚５１上方に突出させて設けると、揺動棚５１の左右方向幅内におけるササリ粒の回収が良好となる。 Furthermore, a rear guide plate 105 may be provided on the rear side (collection chamber 66a side) in the handling chamber 66 and on the feed chain 14 side. As shown in FIGS. 7 and 8, when the rear guide plate 105 is provided behind the mesh presser 77 and protrudes from the feed chain 14 side in the handling chamber 66 to the upper side of the swing shelf 51 in the sorting chamber 50, The recovery of the scorpion grains within the lateral width of the swing shelf 51 is improved.

後方ガイド板１０５が扱室６６に搬送される穀稈の入り口側であるフィードチェン１４側から選別室５０側に突出していると、フィードチェン１４により扱室６６に搬送される穀稈は後方ガイド板１０５の上面に沿って矢印Ｒ方向（図７）に流れる。したがって、扱室６６内の回収室６６ａに搬送される穀稈を扱胴６９の扱歯６９ａ側に寄せることができるため、扱歯６９ａにより株元側にささり込んでいる穀粒を削ぎ落として回収できる。そして、図７及び図８に示すように、後方ガイド板１０５のフィードチェン１４側から選別室５０側への突出端部を扱歯６９ａの先端軌跡に沿うように設けると、より後方ガイド板１０５と扱歯６９ａの相互作用によって削ぎ落としが促進される。 When the rear guide plate 105 protrudes from the feed chain 14 side, which is the entrance side of the cereals conveyed to the handling chamber 66, to the sorting chamber 50 side, the cereals conveyed to the handling chamber 66 by the feed chain 14 are guided backwards. It flows in the direction of arrow R (FIG. 7) along the upper surface of the plate 105. Accordingly, since the cereals conveyed to the collection chamber 66a in the handling chamber 66 can be brought closer to the tooth handling 69a side of the handling drum 69, the grains that are being crushed to the stock side by the tooth handling 69a are shaved off. Can be recovered. Then, as shown in FIGS. 7 and 8, if the protruding end portion of the rear guide plate 105 from the feed chain 14 side to the sorting chamber 50 side is provided along the tip locus of the teeth 69a, the rear guide plate 105 is further provided. The scraping off is promoted by the interaction of the teeth 69a.

このように、扱胴６９の扱歯６９ａにより搬送中の穀稈から除去された穀粒は扱室６６の後方から終端部における除去であっても、揺動棚５１の第２チャフシーブ５４で回収され易い。したがって、本構成を採用することにより、扱室６６内の回収室６６ａ側の被処理物は扱室６６後方の横断流ファン９１又は揺動棚５１の終端部からコンバイン１の外部に排出される三番穀粒の回収ロスとはなりにくく、穀粒の回収効率が向上する。 In this way, even if the grain removed from the cereal being conveyed by the tooth handling 69a of the handling drum 69 is removed from the rear end of the handling chamber 66 at the terminal end, it is recovered by the second chaff sheave 54 of the swing shelf 51. It is easy to be done. Therefore, by adopting this configuration, the object to be processed on the collection chamber 66a side in the handling chamber 66 is discharged to the outside of the combine 1 from the end of the cross flow fan 91 or the swing shelf 51 behind the handling chamber 66. The recovery loss of the third grain is less likely to occur, and the grain recovery efficiency is improved.

更に、後方ガイド板１０５の他に扱胴６９の下方に搬送穀稈を支持する搬送穀稈支持ガイド体１０７を設け、搬送穀稈を支持しても良い。揺動棚５１上方のスペースはほぼ開放されており、このスペースを利用して搬送穀稈支持ガイド体１０７を設けることで、搬送穀稈支持ガイド体１０７と扱胴６９の扱歯６９ａとの相互作用により処理された被処理物は揺胴棚５１上に落下して回収される。搬送穀稈支持ガイド体１０７は、扱胴６９の軸芯に対して平面視斜めに配置し、搬送方向上手側が左寄り、搬送方向下手側が右寄りで左右方向に傾斜を持たせており、フィードチェン１４によって搬送される排藁の穂先側を、扱胴６９後端部の扱歯６９ａの回転域内へ支持案内するものである。 In addition to the rear guide plate 105, a transported culm support guide body 107 that supports the transported culm may be provided below the handling cylinder 69 to support the transported culm. The space above the swing shelf 51 is almost open. By using this space to provide the transporting culm support guide body 107, the transporting culm support guide body 107 and the tooth handling 69 a of the barrel 69 are mutually connected. The object to be processed that has been processed by the action falls on the rocking rack 51 and is collected. The transporting culm support guide body 107 is disposed obliquely in plan view with respect to the axis of the handling cylinder 69, and is inclined leftward and leftward on the upper side in the transporting direction and rightward on the lower side in the transporting direction. The tip of the waste that is conveyed by the above is supported and guided into the rotation region of the tooth 69a at the rear end of the barrel 69.

したがって、本構成を採用することにより、扱室６６後方側（回収室６６ａ側）で扱胴６９により処理され取り除かれた四番穀粒は揺動棚５１においてほぼ全量が回収可能となる。このように、揺動棚５１における四番穀粒の回収が良好となることで、四番穀粒の回収ロスの低減を図ることができる。また、開放されているスペースを有効利用でき、経済的である。 Therefore, by adopting this configuration, almost the entire amount of the fourth grain processed and removed by the handling drum 69 on the rear side of the handling chamber 66 (recovery chamber 66a side) can be collected in the swing shelf 51. As described above, the recovery of the fourth grain in the swing shelf 51 becomes good, so that the recovery loss of the fourth grain can be reduced. Moreover, the open space can be used effectively and is economical.
