[0023] A group of supporting legs 2 are fixedly connected to the bottom surface of the shell 1, and the bottom end of each supporting leg 2 is fixedly connected to an anti-skid seat 3. The supporting legs 2 and the anti-skid seat 3 can be used to place the device firmly and facilitate use. A slag discharge pipe 4 is fixedly connected to the bottom surface of the shell 1, and a control valve 5 is arranged on the outer surface of the slag discharge pipe 4.

The reinforcing ribs 6 can be used to reinforce the motor 11 to make it run more smoothly.
[0024] The outer surface of the shell 1 is fixedly connected with a control box 7 and two first handles 8, respectively. The outer surface of each grading screen bucket 17 is fixedly connected with two second handles 22. The control box 7 is used to facilitate the staff to operate the device. The first handle 8 can be used to move the device, and the grading screen bucket 17 can be taken out by the second handle 22. A cover plate 9 is hinged on the upper surface of the shell 1.

During the placement process, due to the different sizes of the sieve holes of the grading screen bucket 17, it is necessary to place them in sequence from small holes to large holes, and the grading screen bucket 17 can be firmly fixed by using the vertical rod 20 and the fixing plate 19. After completion, the white rice to be screened can be placed in the upper grading screen bucket 17, and then the device is started to run. The motor 11 can drive the rotating rod 13, the supporting plate 14 and the grading screen bucket 17 to rotate at the same time, so that the white rice in the grading screen bucket 17 moves, so that it falls into the lower grading screen bucket 17 in sequence according to size, thereby completing the grading screening. At the same time, since each grading screen bucket 17 is provided with a slag discharge hole 18 on its surface, during its rotation, the slag discharge hole 18 can be used to directly discharge relatively fine slag, which is beneficial to improving efficiency.
