PROBLEM TO BE SOLVED: To solve a problem in a simple tilting type grain lifting tube for discharge in which a tank being a conveyance destination of grain cannot be approached by a tilting space to be tilted because the grain is discharged while the grain lifting tube is tilted.SOLUTION: A terminal of a discharging horizontal spiral 10 in a grain tank 5 is connected to a connection metal 11 provided outside the grain tank 5, and a fixed grain lifting tube 13 connected to the connection metal 11 is provided at a machine body side in a fixed state. A movable discharge tube 14 is turnably provided around a longitudinal axis to the fixed grain lifting tube 13 in the upper part of the fixed grain lifting tube 13, and the movable discharge tube 14 has a length in the axial direction formed shorter than the fixed grain lifting tube 13, and thereby a discharging device 12 is constituted in a combine.COPYRIGHT: (C)2015,JPO&INPIT【課題】簡易の傾動型の排出用揚穀筒では、揚穀筒が斜めになった状態で排出するので、斜めにするための傾動スペース分に穀粒の搬送先であるタンクに接近できないという課題がある。【解決手段】グレンタンク5内の排出横螺旋10の終端はグレンタンク5の外部に設けた接続メタル11に接続し、該接続メタル11に接続した固定揚穀筒13を機体側に固定状態に設ける。、固定揚穀筒13の上部には該固定揚穀筒13に対して前後軸回りに回動自在に可動排出筒14を設け、可動排出筒14は前記固定揚穀筒13よりも軸心方向の長さを短く形成して排出装置12を構成したコンバイン。【選択図】図2
