The through holes on the polishing bin 4 are for ensuring the passage of water mist, and the through holes on the conveying bin 5 are for the passage of hot air. A connecting plate 8 is fixed and penetrated on the opposite side walls of the polishing bin 4 and the conveying bin 5, and the same guide soft board 6 is fixed on the opposite side walls of the polishing bin 4 and the main box 2; the material selection of the guide soft board 6 is preferably but not limited to rubber material, and the rubber material is durable and not easy to damage.
[0027] The main box 2 is provided with a shaking structure for vertically and synchronously shaking the polishing bin 4 and the conveying bin 5 , and the main box 2 is provided with a spray structure for spraying the rice in the polishing bin 4 .
[0028] The shaking structure includes a motor 19 fixedly connected to the vertical outer wall of the main box 2. The output end of the motor 19 extends into the main box 2 and is fixedly connected to a rotating rod 10. A cam 11 is fixedly connected to the rotating rod 10. A rectangular plate 12 is fixedly connected to the vertical inner wall of the main box 2. A limit plate 13 is fixed to the rectangular plate 12. A long plate 14 slides vertically on the limit plate 13. The limit plate 13 limits the long plate 14 to ensure that the long plate 14 shakes stably in the vertical direction. A plate body 15 is fixed to the inner wall of the main box 2. A spring 16 is fixed to the top of the plate body 15. The spring 16 is pulled back and forth, which also plays a buffering and shock-absorbing role to a certain extent. The top and bottom ends of the long plate 14 are fixedly connected to a transmission plate 17. The transmission plate 17 is fixedly connected to a connecting block 18. The two connecting blocks 18 are fixed relative to the polishing chamber 4 and the conveying chamber 5 respectively. The top transmission plate 17 is in contact with the wheel surface of the cam 11, and the bottom transmission plate 17 is fixedly connected to the spring 16.
[0029] The spray mechanism includes a water tank 20 fixedly connected to the top of the main tank 2. A water pump is installed within the water tank 20, which pumps water from the tank 20. A water pipe 21 is fixedly mounted on the water tank 20. The end of the water pipe 21, away from the water tank 20, extends into the interior of the main tank 2 and is fixedly connected to a limit ring 22. A rotating pipe 23 is rotatably connected to the limit ring 22. A spray head 29 is fixedly installed through the bottom of the rotating pipe 23. Water flows through the water pipe 21 and the rotating pipe 23, then moves to the spray head 29 for spraying. The rotating pipe 23 and the water pipe 21 are interconnected.
[0030] The main box 2 is provided with an auxiliary part for rotating the rotating pipe 23 to rotate and spray when the polishing chamber 4 is shaken vertically.
[0031] The auxiliary parts include a rotating shaft 24 rotatably connected to the inner wall of the top of the main box 2, a bevel gear 25 is fixedly provided on the rotating rod 10, a bevel gear 2 26 is fixedly connected to the bottom of the rotating shaft 24, and the bevel gear 1 25 and the bevel gear 2 26 are engaged. A sprocket 27 is fixedly provided on the rotating shaft 24 and the rotating tube 23, and the two sprockets 27 are engaged with the same chain 28.
[0032] The partition 7 is provided with a through-port 19 for facilitating the vertical shaking of the long plate 14, and a plurality of electric heating plates 34 are fixedly connected to the bottom of the partition 7. The setting of the electric heating plates 34 makes the rice in the conveying bin 5 dry, removes the moisture on the surface of the rice, and prevents the rice from getting moldy.
[0033] A polishing rod 30 is rotatably connected to the polishing chamber 4. A plurality of polishing paddles are fixed to the polishing rod 30. A second motor 31 is fixedly connected to the polishing chamber 4 for driving the polishing rod 30. A third motor 32 is fixedly connected to the conveying chamber 5.

[0034] A partition plate 7 is fixedly connected inside the main box 2 . The partition plate 7 is arranged on opposite sides of the polishing chamber 4 and the conveying chamber 5 , and the partition plate 7 and the connecting plate 8 are vertically slidably connected.
[0035] The functional principle of this utility model can be explained through the following operation modes:
[0036] First, the rice to be polished is sequentially added into the polishing bin 4 in the main box 2 through the feed hopper and the guide soft plate 6 .
[0037] The shaking mechanism is activated, and motor 9 begins to operate, driving the rotating rod 10 and cam 11 to rotate. The rotation of cam 11 causes the top transmission plate 17 to move up and down, thereby driving the polishing chamber 4 and the conveying chamber 5 to achieve vertical synchronous shaking through the long plate 14, the pulling spring 16, and the bottom transmission plate 17. This shaking helps to rub the rice against each other during the polishing process, improving the polishing effect and also ensuring that the rice is fully dried.
[0038] At the same time, the spray mechanism also begins operating. Water from the water tank 20 flows through the water pipe 21 into the rotating pipe 23, ultimately being sprayed out from the spray head 29, wetting the rice in the polishing chamber 4. As the polishing chamber 4 shakes vertically, bevel gears 1 25 and 2 26 in the auxiliary unit mesh, rotating the rotating shaft 24. The rotating shaft 24 drives the rotating pipe 23 via the sprocket 27 and chain 28, achieving uniform spraying.
[0039] Inside the polishing chamber 4, the polishing rod 30 rotates under the drive of motor 2 31, and the polishing paddle polishes the rice. The polished rice then enters the conveyor chamber 5 through the connecting plate 8. Inside the conveyor chamber 5, the conveyor rod 33 rotates under the drive of motor 32, and the spiral blades convey the rice to one side. After being heated by the electric heating plate 34, the rice is discharged through the second port 35, completing the polishing and heating process.
[0040] During the whole process, the observation window 3 is convenient for the operator to observe the internal situation of the equipment and adjust the parameters in time to ensure the polishing effect.
[0041] In summary, the rice polishing equipment realizes automatic polishing, wetting and heating treatment of rice through the synergistic effect of the shaking structure, spray structure and polishing transmission structure, thereby improving the efficiency and quality of rice polishing.
[0042] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
