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, and capable of eliminating the clogging of grain culms in the conveyance device.SOLUTION: A combine is equipped with a feeder 30 for conveying grain culms reaped by a reaping part 3 and supplying them to a threshing part. The feeder 30 includes a conveyor 36 with a reaping input shaft 38 for receiving the transmission of power with the lateral direction as the axial direction, 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 accompanying the lifting operation of the feeder 30.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するコンバインを提供する。【解決手段】刈取部3にて刈り取られた穀稈を搬送して脱穀部へと供給するフィーダ30を備えたコンバインであって、フィーダ30は、フィーダハウス35内に、左右方向を軸方向として動力の伝達を受ける刈取入力軸38を駆動軸とするコンベヤ36を有し、コンバインの本機に対して刈取入力軸38を中心とした回動により昇降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の上昇動作にともなって刈取入力軸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を備える。【選択図】図5
