[0025] The working process of the present invention is as follows: the second motor 901 drives one of the screening drums 6 to rotate through the belt 902, and the screening drum 6 drives the other screening drums 6 to rotate synchronously through the transmission belt 8. When the screening drum 6 rotates, when the screening slot 6011 moves into the screening box 302, the arc baffle is completely located in the sliding slot, and the reset spring is in a natural state at this time. At this time, the screening slot is connected to the screening box. After the rice enters the screening slot 6011, the screening drum 6 continues to rotate. When the screening slot 6011 is about to leave the screening box 302, the connecting locking block 702 is just in contact with the damping rotary The baffle plate 305 on the turntable 304 contacts the damping turntable 304, and the damping turntable 304 provides a certain supporting force for the baffle plate 305.

The connecting locking block 702 continues to rotate, and the connecting locking block 702 pushes the baffle 305, the thrust is increased, the damping rotary table 304 drives the baffle 305 to rotate, and the baffle 305 avoids the connecting locking block 702, and does not affect the rotation of the screening drum 6; after the screening drum 6 rotates one circle, the screening groove 6011 is filled with rice, and the rice is confined in the screening groove 6011 by the arc-shaped baffle device 7; the screening drum 6 continues to rotate, and the rice rolls in the screening groove 6011. Under the screening of the screening baffle 605, the broken rice enters the receiving groove 6012, and the whole rice remains in the screening groove 6011, when the broken rice is in the receiving trough 6012, under the action of the conveying spiral bar 6021, the broken rice enters the discharging trough 6042 from the receiving trough 6012, and is finally discharged from the outer end of the discharging shaft 6041, and the broken rice falls into the second receiving box 5. After the screening and separation of the broken rice is completed, when the screening trough 6011 rotates to the lowest point, the locking device 6014 automatically releases the lock on the arc baffle 701, and under the action of the reset spring 703, the arc baffle 701 automatically rebounds into the sliding groove 6013, and the whole rice falls into the first receiving box 4, completing the discharging.
