PROBLEM TO BE SOLVED: To provide a combine harvester allowing the center of gravity of grains in a tank to lower while preventing a capacity reduction of the grain tank further without causing trouble in bottom control of the grain tank.SOLUTION: A part for supporting the tank for swinging the grain tank 6 into a closed posture and an opened posture around the vertically directed shaft center of a traveling machine body is installed in a machine body frame 2. Furthermore, a tank housing space 22 is provided in such a state as to be opened toward the transverse outside of the traveling machine body in the machine body frame 2. The bottom 6a of the grain tank 6 enters the tank housing space 22 in such a state that the grain tank 6 is supported in the closed posture. A mud-removing cover 35 acting on a lid body 30 of a maintenance opening 6b installed in the bottom 6a of the grain tank 6 is disposed under the bottom 6a and in the tank housing space 22.COPYRIGHT: (C)2012,JPO&INPIT【課題】穀粒タンクの容量減少を防止しながらタンク内穀粒の重心を低くすることができ、さらに穀粒タンクの底部管理に支障が生じないコンバインを提供する。【解決手段】穀粒タンク6を走行機体上下向き軸芯まわりに閉じ姿勢と開き姿勢とに揺動させるタンク支持部を、機体フレーム2に設けてある。機体フレーム2にタンク収容空隙22を走行機体横外側向きに開口した状態で設けてある。穀粒タンク6が閉じ姿勢に支持された状態で穀粒タンク6の底部6aがタンク収容空隙22に入り込む。穀粒タンク6の底部6aに設けられたメンテナンス開口6bの蓋体30に作用する泥除けカバー35を底部6aの下方で、かつタンク収容空隙22に配設してある。【選択図】図8
