PROBLEM TO BE SOLVED: To eliminate a clogging trouble occurring in conventional combine harvesters due to the conveyance retardation of ear tip portions, and to dispose the feeding port of a threshing device at a place close to the final end of an ear tip-conveying device as much as possible on the front side of the machine frame to shorten the total machine frame length of a combine harvester.SOLUTION: The combine harvester is characterized by disposing the grain straw-feeding port 2 of the threshing device 1 at a place close to the final end of the ear tip-conveying device 3 for conveying the ear tip sides of reaped grain straws and disposing a rotary raking member 4 on the lower side of the grain straw-feeding port 2, thereby forcibly feeding the grain straw ear tip sides received from the ear tip-conveying device 3 into the threshing device 1 by the raking action of the rotary raking member 4 in the threshing feeding device of the combine harvester.COPYRIGHT: (C)2012,JPO&INPIT【課題】本発明は、従来のコンバインで発生していた穂先遅れによる詰まりを無くすると共に脱穀装置の供給口を穂先搬送装置の終端に極力近づけて脱穀装置を機体の前寄りに配置することでコンバイン全体の機体長を短くすることを課題とする。【解決手段】脱穀装置1の穀稈供給口2を刈取穀稈の穂先側を搬送する穂先搬送装置3の終端に接近して設けると共に該穀稈供給口2の下側に回転掻込体4を設け、該回転掻込体4の掻込作用で前記穂先搬送装置3から引き継いだ穀稈穂先側を脱穀装置1内へ強制的に送り込むよう構成してコンバインの脱穀供給装置を構成した。【選択図】図3
