PROBLEM TO BE SOLVED: To simplify a structure for sufficiently transferring reaped grain straws from an auxiliary conveying device to a feed chain and to reduce the cost.SOLUTION: A combine 1 includes a grain straw-conveying device 55 which transfers the root side of reaped grain straws reaped by a reaping device 54 from a vertical conveying device 74 to the feed chain 90 of a threshing unit 5 through the auxiliary conveying device 75. At a reaping unit 4 of the combine 1, a guide member 101 for guiding the root side of grain straws which guides the root side of the reaped grain straws from the side of the auxiliary conveying device 75 to the side of the feed chain 90 is provided between the rear part of the auxiliary conveying device 75 and the front part of the feed chain 90.COPYRIGHT: (C)2008,JPO&INPIT【課題】刈取穀稈を補助搬送装置からフィードチェンへ良好に受け渡すための構造を簡単なものとして、低コストでの実現を図る。【解決手段】刈取装置54で刈り取った刈取穀稈の株元部を縦搬送装置74から補助搬送装置75を介して脱穀部5のフィードチェン90に受け渡す穀稈搬送装置55を備えるコンバイン1の刈取部4において、前記補助搬送装置75の後部と前記フィードチェン90の前部との間に、刈取穀稈の株元部を補助搬送装置75側からフィードチェン90側へ案内する株元ガイド部材101を設けた。【選択図】図6
