PROBLEM TO BE SOLVED: To provide a simplified grain discharge device intended to simplify its mount constitution on a combine harvester, diminish the damage of carried grains, facilitate relevant works and improve the working efficiency. SOLUTION: In a combine harvester having a reaping section 8 set up in front of a travel unit 7, a threshing device 2 and a grain tank 3 each set up above a machine body frame 1, and the grain discharge device 13 for discharging grains in the grain tank 3, the grain discharge device 13 is constituted by connecting the intermediate portion of a discharging cylinder member 14 having a grain discharge port 16 on the tip and intended to carry grains by the aid of pressurized air from a blower 15 to the grain tank 3, and the grain tank 3 is provided with a discharge mechanism 50 for discharging grains in the grain tank 3, a motor 58 for driving the mechanism 50 and a feeder 57 for joining discharged grains together.
