[0030] Working principle: When the device is homogenizing the sand material, the sand material can be added into the mixing box 11 through the feed hopper. At this time, the motor B19 and the air pump 18 are started to run. The motor B19 can drive the rotating rod 15 to rotate, and then the rotating rod 15 drives the stirring rod 12. The sand material in the mixing box 11 can be stirred by the stirring rod 12. During stirring, the agglomerated sand material can be broken up, and the dust in the sand material will be stirred out. The air flow in the mixing box 11 can be extracted by the air pump 18. At this time, the sand material can be filtered by the filter box 13, and the dust can follow the air flow into the filter box 16, and then the dust is filtered out by the filter screen 17, thereby completing the dust removal of the sand material.

[0031] After the sand material is stirred and broken up, it can fall into the screening plate 3 through the diversion of the guide pipe 10. At this time, the cam 24 can be driven to rotate by the rotating rod 15, and then the cam 24 can rotate along the movable groove 23 to push the movable plate 25 to move back and forth, and then the screening plate 3 is driven by the movable plate 25, so that the screening plate 3 can screen the sand material. Qualified sand material can fall into the conveyor belt 2 and be discharged from the discharge port through the conveyor belt 2. Unqualified sand material can fall into the diversion box 5 through the diversion of the screening plate 3, and then enter the conveying cylinder 7. At this time, the motor A4 is started to run, and the unqualified sand material can be driven by the motor A4 to be transported upward, and then diverted into the crushing bin 8 through the guide pipe 27. The crushing roller 9 is started again to run and the unqualified sand material is crushed by the crushing roller 9. After crushing, it falls on the screening plate 3 for screening, thereby homogenizing the sand material and ensuring uniform sand material particles.

[0032] When the exhaust pipe 20 discharges the airflow, the airflow flows to the nozzle 21 and is sprayed onto the conveyor belt 2, blowing the gravel adhering to the conveyor belt 2 into the collection box 22 for collection, thereby improving the convenience of cleaning the conveyor belt 2.
