PROBLEM TO BE SOLVED: To provide a combine harvester precisely delivering grain culms from a conveying device of a pretreatment part to a feed chain of a threshing device, and preventing disorder of the grain culms by conveying.SOLUTION: The combine harvester conveying the grain culms reaped by the pretreatment part 10 by an ear tip-conveying device 18 and a root-conveying device 21, and delivering the grain culms to the feed chain 26 of the threshing device 25 is constituted as follows. An assistant conveying device 22 for conveying the grain culms with the ear tip-conveying device 18 and the root-conveying device 21 is arranged at the delivering part of the grain culms from the ear tip-conveying device 18 and the root-conveying device 21 to the feed chain 26 and at the position for conveying the root sides of the grain culms from the root-conveying device 21, and the end terminal positions of the conveyance of the ear tip-conveying device 18, the root-conveying device 21 and the assistant conveying device 22 are regulated so as to be the same in the conveying direction of the grain culms.COPYRIGHT: (C)2007,JPO&INPIT【課題】前処理部の搬送装置から脱穀装置のフィードチェーンへ確実に引渡し、かつ穀稈の搬送乱れを防止するようにしたコンバインを提供する。【解決手段】前処理部10で刈取った穀稈を、穂先搬送装置18及び株元搬送装置21により搬送して、脱穀装置25のフィードチェーン26に引渡すようにしたコンバインにおいて、前記穂先搬送装置18及び株元搬送装置21から前記フィードチェーン26への穀稈の引渡し部分にあって、かつ前記株元搬送装置21より穀稈の株元側を搬送する位置に、前記穂先搬送装置18及び株元搬送装置21と共に穀稈を搬送する補助搬送装置22を配置し、前記穂先搬送装置18、前記株元搬送装置21及び前記補助搬送装置22の搬送終端位置を、穀稈の搬送方向で略々同一とした。【選択図】図2
