[0025] One end of the mounting chamber 51 is equipped with a drive shaft 56, and an incomplete gear 55 is provided on the outside of the drive shaft 56. The incomplete gear 55 meshes with the gear ring 53. One end of the mounting chamber 51 is equipped with a drive motor 513.

The top of the sorting chamber 6 is provided with a feed inlet 4.

[0027] Working principle: In the process of sand and soil sorting, the sand and soil are first poured in from the top of the feed inlet 4, and then the drive motor 513 is started. At this time, the drive motor 513 drives the drive shaft 56 and the incomplete gear 55 to rotate. During the rotation, the incomplete gear 55 drives the gear ring 53 to reciprocate. Then the gear ring 53 drives the moving slide bar 52, the first connecting rod 58 and the hammer block 59 to move. Then the hammer block 59 hits the connecting bin 510, and the vibration force generated by the impact is transmitted to the sorting bin 6 and the sand and soil screen plate 10. In the subsequent sorting process, the sorting effect can be improved and the sand and soil can be prevented from clogging the mesh opening of the sand and soil screen plate 10.

[0028] As the toothed ring 53 moves, it uses the protruding teeth 54 to drive the semi-arc toothed ring 511 and the second connecting rod 512 to deflect along the axis. During the deflection, it also drives the connecting shaft 9. Then the connecting shaft 9 drives the sand screen plate 10 to swing back and forth. During the swing, particles of qualified size fall into the bottom of the sorting bin 6 through the mesh and are discharged along the guide pipe 14. Larger particles are intercepted at the top of the sand screen plate 10. After the sand screen plate 10 is tilted, it falls into the interior of the extension bin 3 along the slope and is conveyed to the top of the grinding plate 13 through the sand pipe 2 and the guide plate 11.

[0029] After the sand falls onto the top of the grinding plate 13, the servo motor 15 is started. The servo motor 15 drives the gear 18 to rotate back and forth through the rotating shaft 19. During the rotation, the gear 18 drives the two sets of racks 20 to move up and down in different directions. Then, the racks 20 drive the grinding plate 13 to move up and down through the connecting block 12. During the process of the two sets of grinding plates 13 moving up and down in different directions, the sand is ground to ensure that the size of the sand particles meets the standard.
