[0027] The staff puts the rice into the hopper 7, and the staff pushes the device by hand on the machine base 1. The whole device can be moved to any designated work place through the universal wheel 16. The setting of the universal wheel 16 increases the flexibility and convenience of the device. When shelling is needed, first adjust the discharge valve 10 according to the amount of rice to be discharged, and turn on the motor 61 and the fan 3 at the same time. The discharge valve 10 controls the feeding speed and feeding amount of the rice to prevent a large amount of rice from being discharged and accumulating and reducing the shelling efficiency. The discharge pipe 8 and the guide trough 9 transport the rice to the shelling mechanism 5.

The husked brown rice falls on the conveying plate 2 and is discharged from the discharge port 12, and the rice husks are blown out through the discharge port 42 of the husk collecting cover 4, so that the rice husks are separated from the brown rice, thereby improving work efficiency, eliminating the need to use the husking device for separate screening again, and reducing the labor intensity of the staff. The dust collecting pad 15 can absorb the dust in the husk to make it adhere, so that it will not be directly discharged into the air, reducing the harm of the dust to the staff. At the same time, the brown rice is collected by the conveying plate 2, which is convenient and quick. During the husking process, the staff can observe the husking situation of the internal rice in real time through the protective cover 11.
