[0026] The feeding and dust removal assembly includes a first feeding box 3 fixedly arranged on the rice crushing box 2, a rotating wheel 4 is rotatably arranged in the first feeding box 3, a feeding trough 5 is provided on the rotating wheel 4, and a plurality of feeding troughs 5 are provided, a first servo motor 6 is fixedly arranged on the first feeding box 3, and the output end of the first servo motor 6 is connected to the rotating wheel 4. A connecting box 7 is fixedly arranged on the first feeding box 3, a second feeding box 8 is fixedly arranged on the top of the connecting box 7, a feeding hopper 9 is fixedly arranged on the top of the second feeding box 8, a fixing plate 10 is fixedly arranged on both sides of the top of the feeding hopper 9, a dust removal fan 11 is fixedly arranged on the fixing plate 10, and an air duct 12 is fixedly arranged on the fixing plate 10, and the air duct 12 extends into the second feeding box 8 at one end away from the fixing plate 10. A guide plate 13 is fixedly provided in the second loading box 8 , and both ends of the guide plate 13 extend to below the two air guide pipes 12 . Two collecting plates 14 are fixedly provided in the fixing plate 10 , and the two collecting plates 14 are located below both ends of the guide plate 13 .

[0027] In this example, when the rice is thrown into the crushing box 2, the first servo motor 6 and the dust removal fan 11 are started first. The start of the first servo motor 6 drives the rotation of the runner 4. The start of the dust removal fan 11 sucks dust from the guide plate 13 through the air duct 12. Then the rice is thrown into the second loading box 8 through the feeding hopper 9. In the process of the rice being thrown into the feeding hopper 9, the friction between the rice will separate all the fine particles attached to the rice from the rice. The rice thrown into the second loading box 8 will fall on the guide plate 13. The guide plate 13 will divert the rice thrown into the second loading box 8 to the two sides of the inner side of the second loading box 8. The rice diverted to the two sides of the inner side of the second loading box 8 will fall on the two collecting plates 14 diverted to the inner side of the second loading box 8. When the rice falls on the guide plate 13, since the weight of the rice is greater than the weight of the dust mixed in the rice, this process During the process, the dust mixed in the rice will be separated from the rice. At this time, the air duct 12 will use the suction force provided by the dust removal fan 11 to suck the dust out of the second feeding box 8. Since the weight of the rice is greater than the weight of the fine particles mixed in the rice, and the free fall speed of the heavy particles is greater than the free fall speed of the light particles, when the rice on the guide plate 13 falls to the collecting plate 14, the fine particles mixed with the rice will usually be on the surface of the rice on the collecting plate 14. At this time, the air duct 12 will use the suction force provided by the dust removal fan 11 to suck the fine particles on the surface of the rice on the collecting plate 14 out of the second feeding box 8, and the rice falling on the collecting plate 14 will fall into the connecting box 7. The rice in the connecting box 7 will fill the feeding trough 5 on the rotating wheel 4 below it. When the notch of the filled feeding trough 5 turns downward, the rice in the feeding trough 5 will fall into the rice crushing assembly for crushing.

[0028] By setting the feeding dust removal component, the dust mixed in the rice is separated and removed by the free fall method, and the rice and fine particles falling on the guide plate 13 are layered, and then the layered fine particles are removed according to the weight difference, so as to reduce the degree of dust mixed in the rice. In addition, the rice and fine particles falling on the guide plate 13 can be layered by the free fall method, and then the layered fine particles can be removed according to the weight difference. In this way, the reduction of dust and fine particles in the rice can improve the quality of the processed rice; the rice is transported to the rice crushing component at a uniform speed and in equal amounts for crushing, so as to avoid stockpiling at the rice crushing component due to excessively fast rice feeding speed, thereby affecting the rice crushing efficiency.

[0029] The rice grinding assembly includes a feed plate 15 disposed below the rice crushing box 2, a feed hole 160 is provided on the feed plate 15, a collection box 16 is rotatably provided on the upper end surface of the feed plate 15, a feed port 17 is provided on the inner bottom end of the collection box 16, a grinding box 18 is fixedly provided on the lower end surface of the feed plate 15, a grinding wheel 19 is rotatably provided in the grinding box 18, and the grinding wheel 19 is docked with the collection box 16 on the feed plate 15 through a transmission shaft. A support base 20 is fixedly provided on the lower end surface of the grinding box 18, a second servo motor 21 is fixedly provided in the support base 20, the output end of the second servo motor 21 is docked with the grinding wheel 19 in the grinding box 18, and a discharge pipe 22 is fixedly provided on the grinding box 18.

[0030] In this example, the rice crushed by the rice crushing assembly will fall into the collecting box 16. At this time, the second servo motor 21 is started. The start of the second servo motor 21 drives the grinding wheel 19 to rotate. The rotation of the grinding wheel 19 drives the collecting box 16 to rotate. The rice falling into the collecting box 16 will fall onto the discharge plate 15 through the discharge port 17. The rice on the discharge plate 15 will fall into the grinding box 18 through the discharge hole 160. The rotating collecting box 16 drives the discharge port 17 to rotate. The rotation of the discharge port 17 causes the rice in the collecting box 16 to fall into the grinding box 18 along the inner wall of the grinding box 18. The rice in the grinding box 18 is ground under the rotation of the grinding wheel 19.

[0031] The rice grinding assembly is arranged so that the rice can be evenly spread in the grinding box 18, thus preventing the grinding box 18 from having more rice in some parts and less rice in some parts, which affects the rice grinding efficiency.
