The connecting rod is rotationally connected with a turntable through a connecting column. The bottom of the turntable is fixedly connected with a motor, and the motor is connected with the side wall of the box body through a support plate. By setting the driving motor, the utility model prevents the feed inlet from being blocked due to excessive accumulation of rice, improves the efficiency of rice processing, and then completes the processing of rice through the arranged motor, spring and screen, and further improves the quality of rice processing through a blower.

[0004] However, when the utility model is actually used, when the rice is sieved, the surface of the rice is prone to carry fine dust. The dust is light in weight and is easily adsorbed on the surface of the rice. It is difficult to shake off the dust during vibration, and the dust cleaning is difficult, thus affecting the quality of the sieved rice. Therefore, it needs to be improved. Content of the Utility Model

[0005] The purpose of the utility model is to provide a vibrating screen for rice processing, which has the effects of strong dust removal effect, cleaner surface of the sieved rice, and improved quality of rice.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: a vibrating screen for rice processing, including a vibrating box, the inner wall of the vibrating box is fixedly connected with a screen, the top of the vibrating box is respectively clamped with a first box cover and a second box cover, the top of the first box cover is fixedly connected with a feed hopper, the bottom of the first box cover is movably installed with a mounting frame, the inside of the mounting frame is threadedly connected with a bolt, the bottom of the mounting frame is fixedly connected with a first frame, the bottom of the first frame is fixedly connected with a connecting rod, the bottom of the connecting rod is fixedly connected with a second frame, the inner walls of the first frame and the second frame are both rotationally connected with cleaning rollers, the outer surface of the cleaning rollers is provided with a dust-absorbing cloth layer, and the bottom of the vibrating box is fixedly connected with a support plate.

Static electricity is generated by the friction of the anti-slip plastic plate, which adsorbs dust. The suspension rod supports the connecting frame. There are several rows of anti-slip plastic rods, and there are gaps for the rice to pass through between each row of anti-slip plastic rods. When the rice passes through, it rubs against the anti-slip plastic rods, and the anti-slip plastic rods are charged with static electricity to adsorb dust, making the dust removal more comprehensive. After screening, the anti-slip plastic rods can be taken out of the vibration box to clean the adsorbed dust on the surface. The vibration motor is started to vibrate the vibration box, which is convenient for screening out broken rice. The spring expands and contracts to promote the vibration of the vibration box. The base contacts the ground. The rice after screening and dust removal is discharged from the discharge port, and the broken rice is discharged from the impurity discharge port.
