PROBLEM TO BE SOLVED: To improve working efficiency of grain discharging of a combine harvester.SOLUTION: In the combine harvester, a transferring beginning end part of a vertical transferring part (50) of a discharge auger (8) is communicated with a transferring stopping end part of a discharge screw (42) arranged in the bottom part of a grain tank (6), wherein, the discharge auger is used for discharging the grain in the grain tank (6) to the outside. Besides, one end part of a middle transferring part (53) is communicated with the upper end part of the vertical transferring part (50), and the base part of a transverse transferring part (56) is communicated with the other end part of the middle transferring part (53). In addition, the axial position of the discharge screw (42) is arranged in the location more deviated to the outside of the machine body than the outer end of a crawler (2a) on the right.COPYRIGHT: (C)2013,JPO&INPIT【課題】コンバインの穀粒排出作業の能率を向上させる。【解決手段】上記課題は、グレンタンク(6)に貯留した穀粒を外部へ排出する排出オーガ(8)の縦移送部(50)の移送始端部を、グレンタンク(6)の底部に設けた排出螺旋(42)の移送終端部に連通させる。また、縦移送部(50)の上端部に中間移送部(53)の一端部を連通させ、該中間移送部(53)の他端部に横移送部(56)の基部を連通させる。また、排出螺旋(42)の軸心位置を右側のクローラ(2a)の外側端よりも機体外側に偏倚する位置に配置する。【選択図】図1
