[0002] After the brown rice is milled into cooked rice, a small amount of bran powder is still present on the surface of the rice grains, which affects the appearance quality, storage properties and taste of the cooked rice. Therefore, it is necessary to grind and polish the rice, which is beneficial to completely remove the rice bran on the surface of the rice grains, and can also make the starch on the surface of the rice grains gelatinized, improve the smoothness of the rice, improve the appearance of the rice, and facilitate preservation. After searching: a rice processing grinding and polishing device with patent number CN220514246U belongs to the field of rice processing technology. A rice processing grinding and polishing device includes a frame, a frame groove is provided inside the frame, a feed port is provided at the upper end of the frame groove, a discharge port is provided at the lower end of the frame groove, a loading hopper is fixed to the upper end of the frame, a fixed frame is fixed to the middle of one end of the frame, a stepper motor is fixed to the middle of the fixed frame, a connecting rod is fixed to the driving end of the stepper motor, a first gear is fixed to one end of the connecting rod, a second gear is meshed and connected to the outer surface of the first gear, and a fixing rod is fixed to the middle of the second gear.
[0003] However, the rice processing grinding and polishing device mentioned above still has some shortcomings.

[0026] Specifically, the microdermabrasion and polishing mechanism includes a servo motor 14 fixedly connected to one side of the cover body 5, a guide hopper 7 and a lower grinding disc 11 fixedly connected to the body 1, and a transmission shaft 18 rotatably connected to one side of the body 1. The bottom of the guide hopper 7 is fixedly connected to a discharge pipe 8, and the outer rotating sleeve of the discharge pipe 8 is provided with an upper grinding disc 9, and the outer fixed sleeve of the upper grinding disc 9 is provided with a driven bevel gear 20.

The outer fixed sleeve of the transmission shaft 18 is provided with a driven tooth 17 and a driving bevel gear 19. The driving tooth 16 is meshed with the driven tooth 17, and the driving bevel gear 19 is meshed with the driven bevel gear 20. The upper grinding disc 9 cooperates with the lower grinding disc 11. The rice that has been preliminarily ground and polished falls into the discharge pipe 8 along the guide hopper 7 and finally flows to the top of the lower grinding disc 11. At this time, the worm 15 is driven to rotate by the servo motor 14, and the upper grinding disc 9 is driven to rotate through the transmission of the driving gear 16 and the driven gear 17, as well as the driving bevel gear 19 and the driven bevel gear 20. With the cooperation of the lower grinding disc 11, the rice can be ground and polished again. Under the centrifugal rotation of the upper grinding disc 9, the ground and polished rice can be driven outward from the middle of the lower grinding disc 11 and fall to the top of the filter plate 13. After filtering by the filter plate 13, the rice powder in the grinding and polishing process can be filtered out and fall into the collection box 2, and the ground and polished rice is discharged from the discharge pipe 3.
[0027] Specifically, four connecting rods 12 are fixedly connected to the outer side of the lower grinding disc 11, and the four connecting rods 12 are fixedly connected to the inner side of the body 1 on all sides, which is conducive to supporting and fixing the lower grinding disc 11 without hindering the falling of rice.
[0028] Specifically, a bearing is fixedly sleeved inside the upper grinding disc 9 , and the inner ring of the bearing is fixedly sleeved on the outside of the discharge pipe 8 , so that the upper grinding disc 9 can be rotatably sleeved on the outside of the discharge pipe 8 .
[0029] Specifically, the shaking mechanism includes a worm gear 23 rotatably connected to the inner wall of one side of the cover body 5 and a plurality of springs 21 fixedly connected to the inner wall of one side of the cover body 5. One end of each of the springs 21 is fixedly connected to one side of the filter plate 13. The top of the filter plate 13 is fixedly connected to the force plate 10. The worm 15 is meshed with the worm gear 23. The front side of the worm gear 23 is fixedly connected to a toggle column 22. The toggle column 22 is movably abutted against one side of the force plate 10. When filtering, the worm 15 The rotation drives the rotation of the worm gear 23 and the toggle column 22, so that the toggle column 22 is intermittently in contact with the force-bearing plate 10. When in contact, it will drive the force-bearing plate 10 and the filter plate 13 to move right and stretch the spring 21. When there is no contact, the filter plate 13 is reset to the left under the elastic force of the spring 21, thereby driving the filter plate 13 to reciprocate left and right, greatly improving the efficiency of separating rice and powder, and avoiding the clogging of the filter plate 13 by rice and powder.
[0030] Specifically, a through hole is opened on one side of the body 1, and a slide groove is opened on the inner wall of the other side of the body 1. The filter plate 13 is slidably mounted in the through hole and the slide groove, which can guide the filter plate 13 and make its movement more stable.

[0033] Specifically, a discharge pipe 3 is fixedly connected to the other side of the machine body 1, and the discharge pipe 3 corresponds to the filter plate 13, which facilitates the discharge of rice after grinding and polishing.
[0034] Specifically, a feed port is provided on the top of the machine body 1 , and a feed hopper 6 is fixedly connected to the feed port to facilitate feeding.
[0035] In the present invention, when in use, the rice is slowly poured into the feed hopper 6 and the machine body 1, and the two driving motors 4 drive the rotation of the two grinding rollers 24, thereby performing preliminary grinding and polishing on the rice. Then, the rice falls into the discharge pipe 8 along the guide hopper 7 and finally flows to the top of the lower grinding disc 11. At this time, the servo motor 14 drives the rotation of the worm 15, and the transmission of the driving gear 16 and the driven gear 17, as well as the driving bevel gear 19 and the driven bevel gear 20, drives the rotation of the upper grinding disc 9. With the cooperation of the lower grinding disc 11, the rice can be ground and polished again. Under the centrifugal rotation of the upper grinding disc 9, the ground and polished rice can be driven outward from the middle of the lower grinding disc 11. And it falls to the top of the filter plate 13. After filtering by the filter plate 13, the rice powder in the grinding and polishing process can be filtered out and fall into the collection box 2, and the rice after grinding and polishing is discharged from the discharge pipe 3. During filtering, the rotation of the worm 15 drives the rotation of the worm gear 23 and the toggle column 22, so that the toggle column 22 is intermittently abutted against the force-bearing plate 10. When abutting, it will drive the force-bearing plate 10 and the filter plate 13 to move right and stretch the spring 21. When there is no contact, under the elastic force of the spring 21, the filter plate 13 is reset to the left, thereby driving the filter plate 13 to move back and forth, greatly improving the efficiency of separating rice and powder, and avoiding the clogging of the filter plate 13 by rice and powder.
