PROBLEM TO BE SOLVED: To provide a combine with a configuration having a conveyance device for conveying/supplying grain culms reaped by a reaping part to a threshing part, which is capable of performing an operation in a reverse rotation direction of a conveyor in the conveyance device by a simple structure without causing the complication of the structure, eliminating the clogging of grain culms in the conveyance device, and improving operability of a reverse rotation operation of the conveyor.SOLUTION: A combine 1 is equipped with a feeder 30 for supplying reaped grain culms to a threshing part 7. The feeder 30 includes a conveyor 36 with a reaping input shaft 38 as a drive shaft in a feeder house 35, and is provided so as to be lifted and lowered by the rotation around the reaping input shaft 38 relatively to a combine main machine. The combine includes a reverse rotation mechanism 110 for transmitting a lifting operation of the feeder 30 to the reaping input shaft 38, and rotating the reaping input shaft 38 in a direction opposite to the rotation direction at the time of conveying the grain culms using the lifting operation of the feeder 30, and the actuation/non-actuation of the reverse rotation mechanism 110 is operated by the operation of an operation clutch lever 23.SELECTED DRAWING: Figure 5COPYRIGHT: (C)2019,JPO&INPIT【課題】刈取部にて刈り取られた穀稈を脱穀部へと搬送・供給する搬送装置を備えた構成において、構造の複雑化を招くことなく、簡単な構造により、搬送装置におけるコンベヤの逆転方向への動作を可能とし、搬送装置における穀稈の詰まりの解消を可能とし、しかも、コンベヤの逆転操作の操作性を向上させる。【解決手段】刈り取った穀稈を脱穀部7へと供給するフィーダ30を備えたコンバイン1であって、フィーダ30は、フィーダハウス35内に刈取入力軸38を駆動軸とするコンベヤ36を有し、本機に対して刈取入力軸38を中心として昇降回動するように設けられたものであり、フィーダ30の上昇動作を刈取入力軸38に伝達し、フィーダ30の昇降動作を用いて刈取入力軸38を穀稈の搬送時の回転方向と逆方向に回動させる逆転機構110を備え、作業クラッチレバー23の操作により、逆転機構110の作動・非作動が操作されるように構成されている。【選択図】図5
