PURPOSE:To effectively prevent a blower from being jammed by providing a conveying device for conveying grains to a grain lifting machine installing part, a relaying machine interposed on the way to the main lifting machine, and a thrower type grain lifting device on a device for discharging the grains stored in a grain tank of a combine. CONSTITUTION:A grain tank 9 including a grain discharging device is provided on a combine. There are provided rotary shafts 23, 24 in the grain tank 9, which are coupled with a drive shaft 28 by belts 23a, 24a. The rotary shaft 24 includes a spiral blade 29 mounted therearound to serve as a conveying device 30, and a lifting blade 31 mounted on a final end part thereof. The circumference of the rotary shaft 23 is covered with a casing 33 to form small chambers 35, 36 connected with each other via a passage 34. A spiral blade 39 is attached to the rotary shaft 23 within the small chamber 36 to form a relaying device 40. In addition, a thrower 42 of a grain lifting device 44 is mounted in the thrower case 28. Further, a slidable shutter 46 for blocking the small chambers 36, 35 is mounted on the passage 34. |
