PROBLEM TO BE SOLVED: To provide a combine harvester which is enabled not only to perform a grain supply by using a grain carrying-out auger and a grain flow exit separately but also to avoid easily the extraction leakage of grain at the time of using the grain flow exit.SOLUTION: A combine harvester comprises a discharge screw 50 disposed in the bottom of a grain tank 20, and a grain carrying-out auger 51 communicating with the discharge screw 50. Further comprised is a drive mechanism 66 for rocking and switching the grain tank 20 on an ascending/descending axis Y into an ascending position and a descending position. Still further comprised is a freely openable/closable grain outlet 26 which is formed in such a side wall 25 of the grain tank 20 as faces outward and downward of a running machine body at the ascending position of the grain tank 20.COPYRIGHT: (C)2014,JPO&INPIT【課題】穀粒搬出オーガと穀粒流出口との使い分けによる穀粒供給を行なえるのみならず、穀粒流出口を使用する際の穀粒の取り出し漏れを回避し易くする。【解決手段】穀粒タンク20の底部内に設けた排出スクリュー50と排出スクリュー50に連通する穀粒搬出オーガ51とを備えてある。穀粒タンク20を上昇姿勢と下降姿勢とに昇降軸芯Yまわりに揺動切換え操作する駆動機構66を設けてある。穀粒タンク20の上昇姿勢において走行機体外方向きにかつ下方向きになる穀粒タンク20の側壁25に開閉自在な穀粒流出口26を設けてある。【選択図】図8
