[0029] Working principle: When the device processes the sand material, the sand material can be fed through the feed hopper 11, and the sand material can fall onto the conveyor belt 8 through the guide of the feed hopper 11 and the spreading pipe 10, and be transported through the conveyor belt 8. When feeding, the motor 2 is started to run, and the motor 2 can drive the rotating rod 6 to rotate, and then the rotating rod 6 can drive the spreading pipe 10 to rotate through the transmission component 9, so that the spreading pipe 10 can evenly spread the sand material on the conveyor belt 8 when it rotates, and there will be no accumulation. The evenly laid sand material can enter the diversion trough 28 for diversion when it is transported. At this time, the fan 16 and the heater 17 can be started to run, and the external air flow can be extracted by the fan 16 to dry the sand material, and the air flow can be heated by the heater 17.

When the screening box 22 moves back and forth, it can drive the rack A21 to move. At this time, the rack A21 can drive the gear 20 to rotate back and forth, so that when the dried sand material falls into the mixing box 18, the agglomerated material can be broken up by the stirring of the stirring rod 19. After stirring and breaking up, the sand material can fall into the screening box 22. Through the rocking of the screening box 22, the sand material that meets the standards can be filtered through the sieve plate 23 and fall into the collecting box 24, while the sand material that does not meet the standards can be discharged through the discharge port 25 and fall into the unqualified slot in the collecting box 24.
