PROBLEM TO BE SOLVED: To place an operation lever for displacing a grass dividing guide between a grass dividing active position and a storage position at an upper portion of a grain culm conveyance passage so as to prevent the conveyance action of grain culms from being blocked.SOLUTION: A combine harvester includes a vertically movable reaper/conveyer (7) provided at a front portion of a thresher (2) mounted on a vehicle body (1), and a grain culm conveyer (6) that conveys grain culm reaped by the reaper/conveyer (7) toward the thresher (2) and is disposed between the reaper/conveyer (7) and the thresher (2). In the combine harvester, the grass dividing guide (10) for dividing grain is provided at the outside of the reaper/conveyer (7), and the operation lever (12) for displacing the grass dividing guide (10) between the grass dividing active position and the storage position is provided at a portion upper than the grain culm conveyance passage (9) formed by the grain culm conveyer (6). The operation lever (12) is disposed under a dust cover (40) which is disposed at an upper portion of the grain culm conveyance passage (9).COPYRIGHT: (C)2012,JPO&INPIT【課題】分草ガイドを分草作用位置と格納位置とに切り替える操作レバーを、穀稈搬送通路の上方に配置することで、穀稈の搬送作用を阻害しにくくする。【解決手段】車体(1)上に搭載した脱穀装置(2)の前方に昇降自在な刈取搬送装置(7)を設け、刈取搬送装置(7)と脱穀装置(2)の間には、刈取搬送装置(7)で刈り取った穀稈を脱穀装置(2)へ向けて搬送する穀稈搬送装置(6)を設けたコンバインにおいて、刈取搬送装置(7)の外側部に穀稈を分草する分草ガイド(10)を設け、分草ガイド(10)を分草作用位置と格納位置とに切り替える操作レバー(12)を穀稈搬送装置(6)によって形成される穀稈搬送経路(9)よりも上方の部位に配置する。また、この操作レバー(12)を穀稈搬送通路(9)の上方に配置した防塵用のカバー(40)の下側に配置する。【選択図】図1
