Description

Technical Field

[0002] A rice husker is a device for processing rice. Its working principle is to allow the rice to flow between two parallel and opposite fast and slow rubber rollers that rotate at a certain linear speed difference.

The number of rotary blades 440 is several and they are arranged alternately on the surface of the main shaft 410. The rubber cylinder 430 is fixedly installed on the inner side of the filter cylinder 250 and is located on the outer periphery of the moving disk group 420. The output end of the drive motor 220 is connected to one end of the main shaft 410, and the main shaft 410 is rotatably installed on the inner side of the shelling cylinder 200. The moving disk group 420 includes several adjacently connected eccentric grinding discs 421, and the central axis of each eccentric grinding disc 421 is evenly arranged in a circumferential direction on the outer periphery of the main shaft 410. The air inlet end of the discharge fan 300 is connected to the suction hopper 310 fixed to the bottom surface of the shelling cylinder 200.

[0025] In this embodiment, the discharge fan 300 is a shaftless fan structure, and the air outlet end of the discharge fan 300 is fixedly connected with an interface flange 320, and the interface flange 320 is used to connect with a sandbag to collect rice husks and discharge airflow.

[0026] In this embodiment, a plurality of air inlet grilles 240 are provided on the surface of the shelling cylinder 200 for guiding the airflow to enter.

[0033] Rice is fed at one end of the feed hopper 210 so that the rice grains enter the shelling cylinder 200 and the rubber cylinder 430. When the moving disc group 420 rotates, the moving disc group 420 rotates eccentrically to push the rice to slide along the inner side of the rubber cylinder 430. The surface of the rice is shelled by the relative movement friction between the eccentric grinding disc 421 and the rubber cylinder 430 at the point where the gap between the eccentric grinding disc 421 and the rubber cylinder 430 is the smallest, so that the rice husk outside the rice grain is broken and the shelling work is achieved in the continuous rotation friction of the moving disc group 420 and the mutual squeezing friction between the rice grains. After the grains slide out of the rubber cylinder 430 due to gravity, they are rotated by the conveying rotor 440 to enter the next-level rubber cylinder 430 for shelling again to ensure the shelling rate. After the grains are shelled, the rice husks can be sucked out and collected by the negative pressure of the discharge fan 300 through the filter holes 251 on the surface of the filter cylinder 250, and the rice grains are discharged and collected through the discharge hopper 230.
