[0003] A search revealed that utility model patent CN218637430U discloses a "rice hulling and polishing machine". This rice hulling and polishing machine, through the setting of a filter plate, rotates a motor to drive a second connecting rod to rotate, and the second connecting rod drives a first connecting rod to rotate. The first connecting rod drives the filter plate to reciprocate through a baffle, screening out the floating chaff on the surface of the polished rice. The floating chaff falls into the floating chaff box, which helps to improve the quality of the rice, eliminating the need for further processing and improving polishing efficiency.

[0004] The device is unable to remove the rice husks after the rice has been dehulled, which affects the next step of polishing the rice and results in poor processing quality.

[0005] Therefore, it is necessary to provide a rice hulling and polishing machine to solve the above-mentioned technical problems. Utility Model Content
