PROBLEM TO BE SOLVED: To smoothen the conveyance of grain culms by preventing a nipping guide member from being derailed from a main stream-side conveying chain.SOLUTION: The reaped grain culm conveyor for a combine harvester constituted by joining end terminal parts of a plurality of branch-side conveying routes to the main-side conveying route is equipped with a first nipping guide member (20) for delivering and guiding the reaped grain culms from the terminal end parts of the branch-side conveying routes to the main-side conveying route, and holding the delivered grain culms so as to be elastically displaceable so that the grain culms may be nipped and conveyed between a first nipping guide member (20) and the main side conveying chain (14), derailing-preventing guide members (23, 23) for preventing the first nipping guide member (20) from being derailed from the main side conveying chain (14) in the upper and lower direction by arranging the draining-preventing guide members (23, 23) at the positions sandwiching the first nipping guide member (20) from upper and lower directions, and a stopper (25) for restricting the elastic displacement in the direction of being separated from the main side conveying chain (14) of the first nipping guide member (20).COPYRIGHT: (C)2012,JPO&INPIT【課題】主流側搬送チェンからの挟持ガイド部材の脱線を防止し、穀稈搬送を円滑化する。【解決手段】主流側搬送経路に対して複数の支流側搬送経路の終端部を合流させて構成したコンバインの刈取穀稈搬送装置であって、刈取穀稈を支流側搬送経路の終端部から主流側搬送経路に受け渡し案内すると共にこの受け渡された刈取穀稈を主流側搬送経路に備えた主流側搬送チェン(14)との間で挟持搬送すべく弾性変位可能に保持した第1挟持ガイド部材(20)と、該第1挟持ガイド部材(20)を上下から挟む位置に配置して主流側搬送チェン(14)からの上下方向への脱線を防止する脱線防止ガイド部材(23,23)と、第1挟持ガイド部材(20)の主流側搬送チェン(14)から離間する方向への弾性変位を規制するストッパ(25)を備える。【選択図】 図3
