PROBLEM TO BE SOLVED: To solve the problem in which the support of a grain lifting cylinder of a conventional vertical grain lifting device is unstable.SOLUTION: A thresher 3 is provided above a machine body frame 1 in which a traveling device 2 is provided below. A grain tank 5 is provided at the lateral side of the thresher 3. A terminal of a tank discharge device 10 provided in the grain tank 5 for discharging grains in the grain tank 5 is made to face a connection metal 11. A lower part of a grain lifting cylinder 20 of a vertical grain lifting device 12 is attached to the connection metal 11 so as to be rotatable around a vertical axis. The connection metal 11 connects a horizontal cylinder part 15 on the upstream side of a transportation direction and a vertical cylinder part 30 on the downstream side through a connection part 31 and forms an L shape in a side view. The lower part of the grain lifting cylinder 20 of the vertical grain lifting device 12 is inserted into the vertical cylinder part 30 of the connection metal 11. A turning gear 52 of the grain lifting cylinder 20 is fixed to a predetermined position at the lower side of the grain lifting cylinder 20. An undersurface of the turning gear 52 is brought into contact with a top face of the vertical cylinder part 30 of the connection metal 11.SELECTED DRAWING: Figure 5COPYRIGHT: (C)2016,JPO&INPIT【課題】従来の縦揚穀装置の揚穀筒の支持が不安定となるという課題がある。【解決手段】下方に走行装置2を設けた機体フレーム1の上方に脱穀装置3を設け、脱穀装置3の側方にグレンタンク5を設け、グレンタンク5内に設けたグレンタンク5内の穀粒を排出するタンク排出装置10の終端を、接続メタル11に臨ませ、接続メタル11に縦揚穀装置12の揚穀筒20の下部を縦軸回転自在に取付け、前記接続メタル11は搬送方向の上手側の横筒部15と下手側の縦筒部30とを連結部31により連結して、側面視でL型状に形成し、接続メタル11の縦筒部30には、縦揚穀装置12の揚穀筒20の下部を挿入し、揚穀筒20の下側所定位置には揚穀筒20の旋回用ギヤ52を固定し、旋回用ギヤ52の下面は接続メタル11の縦筒部30の上面に当接させたコンバイン。【選択図】図5
