PROBLEM TO BE SOLVED: To provide a combine harvester capable of preventing unloaded grains in the grains from being dispersed to an unexpected direction by stopping the connection action of an auger clutch synchronously connected to an unloading auger when a tip unloading cylinder is tilted at a prescribed angle or over.SOLUTION: The combine harvester is constituted as follows: the tip unloading cylinder 69 is connected to the end terminal part of an unloading auger cylinder 15 of the unloading auger 14 through a spindle so as to be freely turnable, and the tip unloading cylinder 69 is constituted so that the grains may be unloaded by opening an end terminal opening part of the unloading auger 14 by the downward turning of the tip unloading cylinder 69, and the end terminal opening part of the unloading auger 14 may be closed in a storage state in which the tip unloading cylinder 69 has the axis line nearly equal to that of the unloading auger 14. The auger clutch 25 synchronously connected to the unloading auger 14 is constituted so as not to be connected and operated in a tilted state of the tip unloading cylinder 69 except a downward prescribed angle.COPYRIGHT: (C)2010,JPO&INPIT【課題】先端排出筒が一定の角度以上に傾斜した場合には、排出オーガと連動連結したオーガクラッチの接続作動を停止して穀粒の排出穀粒が予定外の方向に飛散することを防止することのできるコンバインを提供するものである【解決手段】排出オーガ14の排出オーガ筒15の終端部に支軸を介して先端排出筒69を回動自在に連設し、先端排出筒69を下方に回動することにより排出オーガ14の終端開口部が開放されて穀粒の排出を可能に構成し、しかも、先端排出筒69が排出オーガ14と軸線を略同じくした収納状態おいて排出オーガ14の終端開口部は閉塞すべく構成すると共に、先端排出筒69が下向きの一定角度以外の傾斜状態では、排出オーガ14と連動連結したオーガクラッチ25が接続作動しないように構成している。【選択図】図2
