A cleaning brush 6 is rotatably provided between the cleaning shaft 5 and the soil removal ring seat 4. A cleaning spring piece 61 is provided on the brush shaft of the cleaning brush 6. Both the soil removal ring seat 4 and the cleaning shaft 5 are in transmission connection with the motor shaft of the variable frequency motor 2. The cleaning brush 6 is in transmission connection with the soil removal ring seat 4. Thus, the water is conveyed to the onions on the filter screen 41 through the sprinkler head 13 connected to the water inlet pipe 12. At the same time, through the cooperation of the variable frequency motor 2, the installation ring seat 3, the soil removal ring seat 4, the filter screen 41, the cleaning shaft 5, the cleaning brush 6 and the cleaning spring piece 61, the cleaning brush 6 will rotate self while relatively rotating with the filter screen 41. At the same time, when the cleaning brush 6 rotates self, it will drive the cleaning spring piece 61 to turn over the onions, so as to ensure the cleaning effect of the cleaning brush 6 on the onions and prevent the onion skin from being damaged during cleaning. Finally, the muddy water is discharged through the water outlet pipe 14.

[0029] As Figures 2 to 6As shown, a linkage box 21 is provided inside the soil removal box. The motor shaft of the variable-frequency motor 2 rotates and extends into the interior of the linkage box 21. A first linkage shaft 22 and a second linkage shaft 23 are rotatably provided inside the linkage box 21. The first linkage shaft 22 is in transmission connection with the second linkage shaft 23. The first linkage shaft 22 is in transmission connection with the soil removal ring seat 4, and the second linkage shaft 23 is in transmission connection with the cleaning shaft 5. Thus, through the cooperation of the variable-frequency motor 2, the linkage box 21, the first linkage shaft 22 and the second linkage shaft 23, the soil removal ring seat 4 driven by the first linkage shaft 22 rotates relative to the cleaning shaft 5 driven by the second linkage shaft 23, and further, the filter screen 41 on the soil removal ring seat 4 rotates relative to the cleaning brush 6 on the cleaning shaft 5.

[0030] As Figure 5 shown, a first gear 24 is provided on the shaft body of the first linkage shaft 22 inside the linkage box 21, and a second gear 25 is provided on the shaft body of the second linkage shaft 23 inside the linkage box 21. The first gear 24 is meshed and connected with the second gear 25. Thus, through the cooperation of the first gear 24 and the second gear 25, the first linkage shaft 22 and the second linkage shaft 23 rotate synchronously.

[0031] As Figure 5 shown, a first reverse ring 26 is provided on the filter screen 41. A first reverse block 27 is rotatably provided on the first reverse ring 26. The shaft end of the first linkage shaft 22 outside the linkage box 21 is connected to the first reverse block 27. The cleaning shaft 5 is provided on the first reverse block 27. Thus, through the cooperation of the first linkage shaft 22, the filter screen 41, the first reverse ring 26, the first reverse block 27 and the cleaning shaft 5, the cleaning shaft 5 drives the cleaning brush 6 to rotate.

[0032] As Figure 6 shown, an installation groove is provided on the installation ring seat 3. A reverse gear 28 is provided on the shaft end of the second linkage shaft 23 inside the installation groove. A reverse ring gear 29 is rotatably provided at the notch of the installation groove. The reverse gear 28 is meshed and connected with the reverse ring gear 29. The soil removal ring seat 4 is provided on the reverse ring gear 29. Thus, through the cooperation of the second linkage shaft 23, the soil removal ring seat 4, the reverse gear 28 and the reverse ring gear 29, the filter screen 41 on the soil removal ring seat 4 rotates relative to the cleaning brush 6 on the cleaning shaft 5.

[0033] As Figure 4 and Figure 7As shown, a linkage groove is provided on the soil removal ring seat 4. A first linkage ring 62 is rotatably provided at the notch of the linkage groove. A first linkage block 63 is rotatably provided on the first linkage ring 62. One end of the brush shaft of the cleaning brush 6 is rotatably connected to the cleaning shaft 5, and the other end of the brush shaft of the cleaning brush 6 is connected to the first linkage block 63. A self-rotating gear 64 is provided on the first linkage block 63, and a self-rotating ring gear 65 is provided inside the linkage groove. The self-rotating gear 64 is meshed and connected with the self-rotating ring gear 65. Thus, through the cooperation of the soil removal ring seat 4, the first linkage ring 62, the first linkage block 63, the self-rotating gear 64 and the self-rotating ring gear 65, the cleaning brush 6 rotates self when relatively rotating with the filter screen 41.

[0034] As Figure 1 shown, an installation ring plate 15 is provided on the soil removal box body 1. The box body cover plate 11 is arranged on the installation ring plate 15. Lifting handles 16 are symmetrically arranged on the box body cover plate 11. Thus, the box body cover plate 11 is installed on the soil removal box body 1 through the installation ring plate 15, and at the same time, the box body cover plate 11 is opened or closed through the lifting handles 16.

[0035] Working principle: When the variable-frequency motor 2 drives the first linkage shaft 22 to rotate forward, the first linkage shaft 22 will drive the first reverse block 27 connected to the first reverse ring 26 to rotate forward. When the first reverse block 27 rotates forward, it will drive the cleaning brush 6 connected to the cleaning shaft 5 to rotate forward. At the same time, when the first linkage shaft 22 rotates forward, it will also drive the second gear 25 connected to the first gear 24 to rotate. When the second gear 25 rotates, it will drive the reverse gear 28 connected to the second linkage shaft 23 to rotate. When the reverse gear 28 rotates, it will drive the soil removal ring seat 4 connected to the reverse ring gear 29 to rotate in reverse. Thus, the cleaning brush 6 and the soil removal ring seat 4 rotate relatively. When the cleaning brush 6 and the soil removal ring seat 4 rotate relatively, the cleaning brush 6 will drive the first linkage ring 62 connected to the soil removal ring seat 4 to rotate forward. When the first linkage ring 62 rotates forward, it will drive the self-rotating gear 64 connected to the first linkage block 63 to rotate forward. At the same time, when the soil removal ring seat 4 rotates in reverse, it will drive the reverse ring gear 29 to rotate in reverse. Thus, the self-rotating gear 64 rotates self when rotating forward. When the self-rotating gear 64 rotates self, it will drive the cleaning brush 6 connected to the first linkage block 63 to rotate self. Furthermore, the cleaning brush 6 rotates self when relatively rotating with the filter screen 41. It can not only clean the onions through the cleaning brush 6, but also turn the onions through the cleaning elastic pieces 61 driven by the self-rotation of the cleaning brush 6, ensuring the cleaning effect of the onions.
