PROBLEM TO BE SOLVED: To enable a horizontal unloading cylinder at a folding side, constituted so that the horizontal unloading cylinder for unloading the grain from a grain tank may be folded in two, to be smoothly turned by a small operation force in an apparatus for unloading grain in a combine harvester.SOLUTION: The apparatus for unloading the grain in the combine harvester is constituted as follows. An operation tool 25 for carrying out the turning operation of the second horizontal unloading cylinder 11b from an operating part 4 side is pivotally supported by the base terminal side of the second horizontal unloading cylinder 11b, and the second horizontal unloading cylinder 11b is constituted so as to be turnably operated through a lever fulcrum P contacting with a midway part of the operation tool 25. When the midway part of the operation tool 25 is brought into contact with the lever fulcrum P to change the posture of the second horizontal unloading cylinder 11b from a housed posture to a grain-unloading posture, the tip of the operation tool 25 is regulated so as to protrude from the extended line X of the circumference of the first horizontal unloading cylinder 11a in the threshing part 5 side in the plane view and so as to face to the operating part 4.COPYRIGHT: (C)2008,JPO&INPIT【課題】穀粒タンクから穀粒を排出する横向き排出筒を2つ折りに折り畳み可能に構成したコンバインの穀粒排出装置において、折り畳み側の横向き排出筒を少ない操作力でスムーズに揺動できるようにする。【解決手段】第2の横向き排出筒11bの基端側に、この第2の横向き排出筒11bを操縦部4側から揺動操作するための操作具25を枢支し、該操作具25の中途部に当接する梃子支点Pを介して第2の横向き排出筒11bを揺動操作可能に構成すると共に、該第2の横向き排出筒11bを格納姿勢から穀粒排出姿勢に姿勢変更すべく梃子支点Pに操作具25の中途部を当接させた時、平面視における当該操作具25の先端が第1の横向き排出筒11aの脱穀部5側外周の延長線Xから突出して操縦部4に臨むように構成した。【選択図】図5
