The bottom inner wall of the box body is funnel-shaped for convenient and rapid feeding. A dust removal mechanism is provided on the box body. The dust removal mechanism includes: an air suction hood and a dust prevention box. The air suction hood is fixedly connected to the inner wall of the back of the box body, and the air suction hood is funnel-shaped. The dust prevention box is fixedly connected to the back of the box body. A suction fan is fixedly installed on the top of the dust prevention box. The input end of the suction fan is fixedly connected with an air suction pipe, and the other end of the air suction pipe is fixedly connected to the back of the air suction hood and is connected in a communicating manner. The output end of the suction fan is fixedly connected with an exhaust pipe, and the other end of the exhaust pipe is fixedly connected to the top of the dust prevention box and is connected in a communicating manner. A dust prevention net is fixedly connected to the inner wall of the dust prevention box. This screening device can suck the dust generated during the screening process of rice through the provided dust removal mechanism, filter the air, prevent the dust from flying around and polluting the environment, and at the same time reduce the impact of dust on the respiratory tract of the operator, improve the physical health of the operator. Through the provided rotating mechanism, the sieve plate can vibrate up and down reciprocally under the action of the self-elastic force of the spring to screen the rice, thereby preventing the screening holes from being blocked and improving the screening speed of the rice.

[0004] When using the above screening device, after the rice is poured into the box body, the motor drives the top plate to rotate, thereby pushing the sieve plate to move up and down. When the top plate rotates, it will damage the rice in the box body, thereby reducing the weight of the screened rice and causing losses of rice. In addition, the sieve plate realizes the vibration effect through the rotation of the top plate and the elastic force of the spring. As the use time increases, the elastic force of the spring will decrease, the vibration effect will decrease, and the efficiency of rice screening will be reduced.
