The output end of the third motor rotates to drive the rotating rod 21 and the stirring rod 22 to stir the rice raw material to prevent its accumulation from affecting the feeding. The rotation of the output end of the first motor can drive a rice milling roller 2 to rotate. Under the action of a pair of gears, the other rice milling roller 2 rotates at the same time to grind the rice raw material. The exhaust end of the exhaust fan 18 draws the air in the bran collecting box 16, so that the bran suction bucket 4 can draw the rice bran in the crushed rice raw material. The rice bran is made to flow from the bran suction bucket 4 and the connecting pipe 17 into the bran collecting box 4, and the filter screen 20 can block the rice bran to prevent the rice bran from being discharged to the outside, the electric fan 23 rotates to blow the fallen rice raw material, and the rice bran missed by the bran suction bucket 4 is blown away, the second motor output end rotates to drive the rotating shaft 14 and the cam 15 to rotate at the same time, and the cam 15 rotates to drive the sliding rod 10 and the connecting rod 11 to move, so that the screening frame 7 drives the screen 8 to vibrate, so that the screen 8 can screen the rice raw material, and at the same time, the screened rice raw material falls into the shell 5 through the through opening 6, and the rice raw material bran removal is completed, which brings convenience to people.
