PROBLEM TO BE SOLVED: To secure the ahead power of sweep auger toward the direction of revolution and to prevent grain from being damaged. SOLUTION: A driving wheel 5 for the revolution of a sweep auger 4 laterally installed in a rice-cabin 1 is provided at the back of the peripheral wall 3 side of the sweep auger 4. The driving wheel 5 is pressed against the peripheral wall 3 with its rotary shaft center D vertically positioned. In this case, it is desirable that the rotary shaft center D of the wheel 5 should be slightly tilted forward for acting the ahead power toward the front, downward direction and that the wheel 5 positioned between a support wheel 6 and an end wheel 7 in the back. Also it is desirable that a moving blade 14 should be installed at the front of the peripheral wall 3 side of the sweep auger 4 for sweeping grain toward a central part.
