PROBLEM TO BE SOLVED: To provide technologies for preventing the clothes, etc. of an operator from being easily caught in a feed chain when the operator performs manual stripping work using a combine harvester.SOLUTION: The combine harvester which drives respective work devices by dividing the drive force of an engine (14) includes: a feed chain drive clutch (29) for intermittently continuing the transmission of the power to a drive passage of the feed chain (12) of a thresher (4); and a feed chain brake (31) on the downstream side of transmission of the feed chain drive clutch (29). The combine harvester also includes an emergency stopping controller (43) for simultaneously operating the feed chain drive clutch (29) and the feed chain brake (31) at such a position on a side of a machine body of the combine harvester as to be operated by the operator in the manual stripping work.COPYRIGHT: (C)2012,JPO&INPIT【課題】コンバインで手扱ぎ作業を行っている際に、作業者の衣服等がフィードチェンに巻き込まれにくくする技術を提供する。【解決手段】エンジン(14)の駆動力を分岐して各作業装置を駆動するコンバインにおいて、脱穀装置(4)のフィードチェン(12)の駆動経路に動力の伝動を断続するフィードチェン駆動クラッチ(29)を設けると共にこのフィードチェン駆動クラッチ(29)の伝動下手側にフィードチェンブレーキ(31)を設け、手扱ぎ作業時に作業者が操作可能なコンバインの機体側部の位置に、フィードチェン駆動クラッチ(29)とフィードチェンブレーキ(31)を同時に作動させる緊急停止操作具(43)を設ける。【選択図】図7
