As shown in fig. 1, the grain box 5 has a peripheral wall including four wall portions, i.e., a front wall 5A, a rear wall 5B, a left side wall 5C, and a right side wall 5D, as an outer peripheral portion, and a top plate 5E covering an upper side. As shown in fig. 2, a grain inlet 15 is provided in the left side wall 5C of the grain tank 5. Further, a screw type grain conveying device 16 is provided, which connects the threshing device 4 and the grain inlet 15, conveys the threshed grains from the threshing device 4 to the grain inlet 15, and feeds the grains from the grain inlet 15.
The grain and straw harvested by the harvesting unit 1 is transported to a threshing device 4. The harvested grain stalks are threshed in a threshing device 4. The threshed grains are carried from the threshing device 4 to the grain inlet 15 by the grain carrying device 16, and are thrown into the grain tank 5 from the grain inlet 15 and stored.
