PROBLEM TO BE SOLVED: To provide a combine capable of performing grain discharge work efficiently in an extension posture of a grain discharge auger, and discharging grains smoothly in a shortened posture.SOLUTION: In a grain tank 4, a flow plate 21, which covers an upper side of a grain discharge spiral 13 discharge-conveying grains on a bottom part of the grain tank 4 to a grain discharge auger 15 side so as to include a grain flow path, is arranged so as to be switched between a vibration drive state of forcibly flowing down the grains and a vibration stop state of naturally flowing down the grains. A discharge rotation speed of a spiral of the grain discharge auger 15 is a dry grain discharge rotation speed for discharging dry grains when a tip grain discharge auger 15d is in a maximum extension posture. Selection can be made between a dry grain discharge work of discharging the grains by vibration-driving the flow plate 21 when the grain discharge auger 15 is in an extension state and a wet grain discharge work of discharging the grains by vibration-stopping the flow plate 21 when the grain discharge auger 15 is in a shortened posture.COPYRIGHT: (C)2016,JPO&INPIT【課題】穀粒排出オーガの、伸長姿勢で穀粒排出作業を能率よく行うと共に、短縮姿勢において穀粒の排出をスムーズにすることができるコンバインを提供する。【解決手段】穀粒タンク4内に、その底部で穀粒を穀粒排出オーガ15側に排出搬送する穀粒排出螺旋13の上方を穀粒流路を有して覆う流板21を、穀粒を強制流下させる振動駆動状態と、穀粒を自然流下させる振動停止状態とに切換え自在に設け、且つ前記穀粒排出オーガ15の螺旋体の排出回転数を、先端穀粒排出オーガ15dを最伸長姿勢にしたとき乾燥穀粒を排出させる乾燥穀粒排出回転数とし、前記穀粒排出オーガ15が伸長姿勢にあるとき流板21を振動駆動させて穀粒を排出する乾燥穀粒排出作業と、穀粒排出オーガ15が短縮姿勢にあるとき流板21を振動停止させて穀粒を排出する濡れ穀粒排出作業とを選択自在に構成した。【選択図】図1
