Therefore, through the setting of the spiral rod 303, the rice grains stay in the cleaning cylinder 204 for a longer time, so that the rice grains are cleaned more thoroughly.

[0038] The guide mechanism 3 also includes a threaded rod 306 threadedly inserted into the surface of the movable plate 301, one end of the threaded rod 306 is fixedly connected to a servo motor 307 fixedly connected to the inside of the hollow cylinder 103, the movable plate 301 is slidably connected to the inside of the hollow cylinder 103 through the servo motor 307 and the threaded rod 306, both sides of the surface of the movable plate 301 are slidably inserted with guide rods 308 fixedly connected to the guide cylinder 201, the setting of the guide rod 308 makes the movable plate 301 more stable when sliding, the guide cylinder 201 is sealed by the sliding plate 202, so that the inside of the guide cylinder 201 can store cleaning water, the servo motor 307 is started, and its output end drives the threaded rod 306 to rotate, so that the movable plate 301 slides inside the hollow cylinder 103 and the guide cylinder 201, so that the movable plate 301 drives the rice grains to be soaked and cleaned inside the guide cylinder 201, so that the rice grains are cleaned more thoroughly;

[0039] The guide mechanism 3 also includes a push block 309 slidably sleeved on the surface of the guide rod 308, and a return spring 310 fixedly connected to the guide cylinder 201 is fixedly connected to the surface of the push block 309.

Cleaning mechanisms 4 are installed on both sides of the surface of the bracket assembly 1. The cleaning mechanism 4 includes a linkage box 401 installed on the surface of the bracket assembly 1. The downward movement of the movable plate 301 drives the push block 309 to move synchronously, so that the push block 309 pushes the sliding plate 202 to move downward, compressing the elastic rod 203, so that the sliding plate 202 no longer seals the guide cylinder 201, so that the rice grains on the surface of the movable plate 301 and the soaking water inside the guide cylinder 201 enter the interior of the linkage box 401;

[0040] A cleaning bin 402 connected to the linkage box 401 is fixedly connected to one side of the linkage box 401. Two corresponding cleaning rollers 403 are rotatably connected to the interior of the cleaning bin 402 through a bearing seat. Linkage gears 404 are fixedly connected to the surfaces of the two cleaning rollers 403. The two linkage gears 404 are meshed with each other. One end of one of the cleaning rollers 403 is fixedly connected to a cleaning motor 405 fixedly connected to the cleaning bin 402. A discharge chute 406 is provided on one side of the cleaning bin 402. The cleaning motor 405 is started to drive the corresponding cleaning roller 403 to rotate at its output end. The linkage gear 404 is set so that the two cleaning rollers 403 rotate in opposite directions to squeeze the rice grains, thereby absorbing the water droplets on the surface of the rice grains, so that the rice grains can be dried after being cleaned, which is convenient for subsequent processing of the rice grains.

[0041] Ventilation fans are installed on both sides of the surface of the cleaning bin 402, and drainage grooves 407 are provided on the lower surface of the linkage box 401 in a path array. A filter screen plate 408 corresponding to the cleaning bin 402 is fixedly connected inside the linkage box 401.

The surface of the cleaning roller 403 is attached with a scraper plate 409 fixedly connected to the cleaning bin 402. Through the setting of the scraper plate 409, after the cleaning roller 403 cleans the water droplets on the rice grains, the surface of the cleaning roller 403 is squeezed by the rotation of the cleaning roller 403, so that the water droplets adsorbed inside the cleaning roller 403 are squeezed out, which facilitates the secondary use of the cleaning roller 403.

[0042] Specifically, when the rice grain cleaning device is in use: the feeding pipe 205 is set so that the rice grains enter the feeding pipe 205, so that the rice grains fall onto the surface of the corundum roller 207, the driving device 209 is started to drive the corresponding corundum roller 207 to rotate, and the driving gear 208 is meshed so that the corresponding corundum roller 207 rotates in the opposite direction, so that the bran powder on the surface of the rice grains is cleaned by the nano brush on the surface of the corundum roller 207, which facilitates the subsequent cleaning of the rice grains, and the bran powder on the surface of the corundum roller 207 is cleaned by the cleaning plate 212, so that the bran powder is prevented from adhering to the surface of the nano brush and affecting the cleaning of the rice grains by the corundum roller 207;

[0043] The rice grains are transported to the inside of the cleaning cylinder 204 through the feeding pipe 205, so that the rice grains fall on the surface of the spiral rod 303. By starting the driving motor 302, the output end of the driving motor 302 drives the spiral rod 303 to rotate, so that the rice grains are transported inside the cleaning cylinder 204. Then, through the setting of the water inlet pipe 304, water in the external water source is sprayed through the atomizing nozzle 305 to clean the rice grains on the surface of the spiral rod 303. Therefore, through the setting of the spiral rod 303, the rice grains stay in the cleaning cylinder 204 for a longer time, so that the rice grains are cleaned more thoroughly.

[0044] After the rice grains are cleaned by the atomizing nozzle 305, the rice grains fall onto the surface of the movable plate 301. The sewage after cleaning is discharged through the filter cylinder 211, thereby avoiding the secondary impact of the sewage on the rice grains. After the sewage is discharged, the guide cylinder 201 is sealed by the sliding plate 202, so that the cleaning water can be stored inside the guide cylinder 201. The servo motor 307 is started, and its output end drives the threaded rod 306 to rotate, so that the movable plate 301 slides inside the hollow cylinder 103 and the guide cylinder 201, so that the movable plate 301 drives the rice grains to be immersed and cleaned inside the guide cylinder 201, so that the rice grains are cleaned more thoroughly.

[0045] When the rice grains are soaked, the movable plate 301 moves downward, driving the push block 309 to move synchronously, so that the push block 309 pushes the sliding plate 202 to move downward, compressing the elastic rod 203, so that the sliding plate 202 no longer seals the guide cylinder 201, so that the rice grains on the surface of the movable plate 301 and the soaking water inside the guide cylinder 201 enter the interior of the linkage box 401, and the rice grains and the soaking water mixture are filtered by the setting of the filter screen plate 408, so that the soaking water is discharged from the linkage box 401 through the drainage groove 407, so that the soaking water no longer mixes the rice grains, and the rice grains slide to the interior of the cleaning bin 402 through the setting of the filter screen plate 408, and the cleaning motor 405 is started, so that the output end of the cleaning motor drives the corresponding cleaning roller 403 to rotate, so that the two cleaning rollers 403 rotate in opposite directions through the setting of the linkage gear 404, squeeze the rice grains, so as to absorb the water droplets on the surface of the rice grains, so that the rice grains are dried at the same time after being cleaned, which is convenient for the subsequent treatment of the rice grains;

[0046] And by setting the scraper plate 409, after the cleaning roller 403 cleans the rice grains and water droplets, the cleaning roller 403 rotates to squeeze the surface of the cleaning roller 403, so that the water droplets adsorbed inside the cleaning roller 403 are squeezed out, which facilitates the secondary use of the cleaning roller 403.

[0047] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
