[0027] A rotating shaft 12 is rotatably arranged on the material distributing convex block 10. The rotating shaft 12 passes through the feeding pipe at the bottom of the impurity removing hopper 11 and rotates and extends into the rice washing bucket 8. A disturbing rod 13, a pushing plate 14, and a stirring blade 15 are arranged on the rotating shaft 12 from top to bottom in sequence.

[0029] During specific use, first add clear water into the rice washing tank 1 through the feeding hopper 2. The clear water added into the rice washing tank 1 will pass through the conduit 16 and enter the water collection area 9. The water level in the water collection area 9 can be observed through the transparent observation window 31. Only after adding the clear water can the rice washing operation be started.

[0030] When washing rice, add the rice into the feeding hopper 2 and start the first motor 20, the water pump 23, and the second motor 30. The water pump 23 can pump out the water in the water collection area 9 and send the water into the feeding hopper 2 and the rice washing bucket 8 respectively through the water delivery pipe 25 and the shunt pipe 26. The first motor 20 drives the gear 21 to rotate, the gear 21 drives the toothed ring 22 to rotate, and the toothed ring 22 drives the feeding hopper 2 to rotate. By rotating the feeding hopper 2, the water delivery pipe 25 can flush the feeding hopper 2 along the circumferential direction of the feeding hopper 2 to prevent the rice from sticking to the inner wall of the feeding hopper 2. The second motor 30 drives the rotating shaft 12 to rotate, and the rotating shaft 12 drives the stirring rod 13, the push plate 14, and the stirring blade 15 to rotate.

[0031] The rice in the feeding hopper 2 enters the rice washing tank 1 along with the water flow and first falls onto the material dividing convex block 10. After being dispersed by the material dividing convex block 10, it falls onto the impurity removing hopper 11 more evenly and dispersedly. The fine solid impurities mixed in the rice are separated through the filter holes on the impurity removing hopper 11, so that the water and fine impurities first pass through the filter holes and fall onto the partition plate 5, and then are concentrated in the water collection area 9 through the conduit 16. The rice enters the rice washing bucket 8 through the feeding port at the bottom of the impurity removing hopper 11. The rotation of the stirring rod 13 can prevent the rice from blocking the feeding port at the bottom of the impurity removing hopper 11. The rotation of the push plate 14 can push the floating impurities floating at the mouth of the rice washing bucket 8 into the water collection area 9. The rotation of the stirring blade 15 can turn over and wash the rice in the rice washing bucket 8.

[0032] This rice washer can automatically separate the impurities in the rice and improve the washing effect of the rice. The circulating flushing mechanism 3 can recycle the water resources and reduce the waste of water resources. The filter screen 27 can intercept the impurities inside the water collection area 9 to prevent the impurities from participating in the water cycle again. After the rice washing is completed, just turn off the first motor 20, the water pump 23, and the second motor 30, and open the first solenoid valve 18. The washed rice can be discharged through the discharge pipe 17. When it is necessary to discharge the water in the water collection area 9, just open the second solenoid valve 29, and the water in the water collection area 9 can be discharged through the sewage discharge pipe 28.

[0033] In summary, this solution is provided with a material distribution bump 10 and a impurity removal hopper 11. The top of the material distribution bump 10 is arc-shaped, and the impurity removal hopper 11 is provided with filter holes, so that the rice falling on the material distribution bump 10 can be dispersed, and the rice can fall into the impurity removal hopper 11 more evenly. The small solid impurities mixed in the rice can be filtered and separated through the filter holes on the impurity removal hopper 11, so that the solid impurities can pass through the conduit 16 and be concentrated in the water collection area 9. In this solution, the rotating shaft 12 can drive the disturbance rod 13, the push plate 14 and the stirring blade 15 to rotate. By rotating the disturbance rod 13, it can prevent the rice from blocking in the feeding pipe at the bottom of the impurity removal hopper 11. By rotating the push plate 14, the floating impurities floating at the mouth of the rice washing bucket 8 can be pushed into the water collection area 9. By rotating the stirring blade 15, the rice in the rice washing bucket 8 can be turned and washed. In this solution, the first motor 20 can drive the feeding hopper 2 to rotate. Due to the rotation of the feeding hopper 2, the water flowing out of the water delivery pipe 25 can wash the feeding hopper 2 more comprehensively. This solution is provided with a circulating flushing mechanism 3, and the circulating flushing mechanism 3 can recycle the water resources and reduce the waste of water resources.
