[0039] In this embodiment, a control groove is provided on the top of the material feeding moving baffle 26, and a control protrusion 25 is rotatably disposed inside the control groove; the control groove facilitates the control protrusion 25 to drive the material feeding moving baffle 26 to reciprocate linearly after rotation.

[0040] In this embodiment, the debris screening plate 31 is inclined, the striking block 34 is elliptical in shape, and the striking block 34 is made of soft rubber.

[0041] In this embodiment, the diameter of the pulley 18 on the outer side of the first rotating shaft 11 is larger than the diameter of the pulley 18 on the outer side of the drive shaft 16. The dust discharge fan blade 17 needs to rotate at high speed, while the material feeding baffle 26 needs to move evenly and stably to feed the material. The smaller pulley 18 can drive the larger pulley 18 to decelerate, thereby making the device operate more stably.

[0042] The specific operation is as follows: Rice is placed inside the feed box 6, and the controllable motor 15 is started. After starting, the motor 15 drives multiple first rotating shafts 11 and the rice hulling rollers 12 through the cooperation of the drive shaft 16, pulley 18, synchronous belt 19, and transmission gear 13, thus hulling the rice. After the first rotating shafts 11 rotate, they drive the second rotating shaft 22 and the turntable 24 through the first bevel gear 23. The turntable 24 and the control protrusion 25 work together to achieve the reciprocating linear motion of the feeding moving baffle 26. The cooperation between the feeding moving baffle 26 and the feeding trough above the feeding fixed baffle 27 ensures uniform feeding of the rice, preventing excessive rice from being fed at the same time. After hulling, the rice grains are discharged from the dust discharge guide frame 8 through the cooperation of the drive shaft 16 and the dust discharge fan blade 17. More impurities and rice grains can fall to the top of the impurity screening plate 31. The rice grains can be screened and discharged from the dust discharge guide frame 8 through the discharge guide block 7. When the second rotating shaft 22 rotates, it can drive the movable shaft 32 and the striking block 34 to rotate through the cooperation of the second bevel gear 33. After the striking block 34 rotates, it can make the impurity screening plate 31 vibrate, preventing the rice grains above the impurity screening plate 31 from accumulating, so that the screening effect of the device is better. After the impurity discharge baffle 36 is opened, the impurities can be discharged and collected.
