PURPOSE:To properly prevent the adhesion of the muck on the box interior and the remains of rice grains on the bottom by connecting or removing a rotating unit to or from a connection control unit, transferring a sweeper to both positions, sweep and non-sweep, and sweeping the inner wall of the box in a very short time with the sweeper. CONSTITUTION:When the interior of a grain lifter is to be swept, an erecting solenoid portion provided on a sweeper erecting/prostrating connection control unit 8 is operated to protrude a rack 20A inside the wall surface, a pinion 19 pivotally fitted to the screw shaft 10 of a sweeping device provided on a rotary belt 5 is engaged with the rack 20A to be rotated in the positive direction, both screw holes 11, 12 are shifted to both sides respectively via the positive direction of the screw shaft 10, individual fitting frames 13, 14 are expanded into a predetermined shape, a sweeper erecting/prostrating hook plate 15 is pushed up by an erecting/prostrating support shaft 17 to erect a sweeper 6. The erected sweeper 6 and a bucket are rotated in the box, and the muck adhering to the inner surface of the wall and rice grains remaining on the bottom are swept by this sweeper 6, received into the bucket and discharged outside. |
