PROBLEM TO BE SOLVED: To smoothly transfer reaped grain culms from a grain culm conveyance device arranged in a reaping conveyance device to a receiving chain and a feed chain.SOLUTION: In a combine harvester, an operator seat (19) is arranged at a front right section of a vehicle body (1) having left and right crawlers (18). A thresher device (2) is arranged at a left rear section of the operator seat (19). A reaping conveyance device (3) is arranged in front of the thresher device (2). A receiving chain (11) and a feed chain (10) which receive the reaped grain culms from a grain culm conveyance device (27) arranged in a reaping conveyance device (3) and convey them are provided. A mission case (9) for driving the reaping conveyance device (3) is arranged at a section in front of the threshing device (2). The driving force is input from a shaft (12) arranged at a rear part of the mission case (9), and is output from a shaft (15) arranged at a front part of the mission case (9) to the reaping conveyance device (3).COPYRIGHT: (C)2014,JPO&INPIT【課題】刈取搬送装置に備えた穀稈搬送装置から受継ぎチェンとフィードチェンへ刈取穀稈を円滑に受け継ぐことができるものとする。【解決手段】左右のクローラ(18)を備えた車体(1)の前部右寄りの部位に操縦席(19)を設け、操縦席(19)の左側後部には脱穀装置(2)を設け、脱穀装置(2)の前側に刈取搬送装置(3)を設けたコンバインにおいて、刈取搬送装置(3)に備えた穀稈搬送装置(27)から刈取穀稈を受け継いで搬送する受継ぎチェン(11)とフィードチェン(10)を設け、刈取搬送装置(3)を駆動する伝動ケース(9)を脱穀装置(2)の前方の部位に配置し、伝動ケース(9)の後部に備えた軸(12)から駆動力を入力し、伝動ケース(9)の前部に備えた伝動軸(15)から刈取搬送装置(3)側へ出力する構成とする。【選択図】図2
