[0025] Working principle:

[0026] Working status

[0027] When the rice needs to be polished, the user pours the unpolished rice from the hopper 10 into the housing 1, and turns on the external power supply of the servo motor 302. The servo motor 302 starts to work, and the output end of the servo motor 302 drives the roller body 303 to rotate. The rotation of the roller body 303 also drives the material stripping bar 305 to rotate, so that the material stripping bar 305 moves the unpolished rice up and down on the arc plate 401 for friction, so that the unpolished rice is polished on the arc plate 401, and the polished rice is polished. The volume of the body becomes smaller, and the rice will fall downward from the filter screen 402 on the surface of the arc plate 401, and will fall to the second polishing structure at the lower end after being guided by the direction of the first material guide hopper 9, and will be moved again by the roller body 303 with denser material strips 305 than the upper end, which will accelerate the speed of the second polishing of the rice and improve the polishing effect of the rice. Finally, the rice will fall outward from the discharge barrel 12 into the collecting box 6 under the guidance of the second material guide hopper 9, and the discharge pipe 403 can also be used to bag the polished rice.

[0028] Collection Phase

[0029] The external power supply of the exhaust fan 405 is turned on, and the exhaust fan 405 starts to work. The suction force generated by the exhaust fan 405 during operation, due to the weight of the rice and the polished rice husk of the rice, enables the air volume generated by the extraction pipe 403 to extract the rice husk and debris from the rice to the installation box 404, and follows the fluidity of the exhaust pipe 406 into the externally installed breathable mesh bag for collection.
