[0042] The driving mechanism is disposed in the housing 2 and is used to drive the first annular block 3 and the second annular block 5 to rotate.

[0043] Specifically, the driving mechanism includes:

[0065] Working principle: First, the staff starts the driving member 11 and the vibrator 15, and adds rice from the feeding hopper and the feeding port to the first cylindrical filter 4. At this time, the output end of the driving member 11 drives the rotating shaft 9 and the gear 10 to rotate, so that the gear 10 drives the outer ring gear 7 and the inner ring 8 to rotate at the same time. At this time, the rotation of the outer ring gear 7 drives a pair of first annular blocks 3 and the first cylindrical filter 4 to rotate, so that the first cylindrical filter 4 screens the rice. At this time, the larger rice grains remain in the first cylindrical filter 4 and are discharged from the first outlet 12, which is convenient for the staff to collect. Smaller rice grains fall into the second cylindrical filter 6. At the same time, the rotation of the inner gear ring 8 can drive a pair of second annular blocks 5 and the second cylindrical filter 6 to rotate. The rotation of the second cylindrical filter 6 can screen the rice grains again, and the broken impurities in the rice grains are screened out. At the same time, the rice grains in the second cylindrical filter 6 are discharged from the second outlet 13, which is convenient for the staff to collect. At this time, the vibrator 15 vibrates the lower wall of the shell 2, and the broken impurities on the lower wall surface inside the shell 2 flow out of the shell 2 through the third outlet 14, which is convenient for the staff to collect, bringing convenience to people.
