[0021] The screening mechanism 1 includes a screen 7 and a support platform 8. The screen 7 is slidably arranged on the support platform 8 and is arranged above the conveyor belt 6. Unqualified particles screened out will remain on the screen 7, and qualified regenerated sand particles will fall onto the conveyor belt 6 through the screen 7 for transportation. A fixed block is fixedly connected to the screen 7, and the fixed block is slidably arranged on the support platform 8. A lever 10 for sliding the fixed block is also fixedly connected to the output shaft of the motor 3. A cross plate 11 is fixedly arranged on the support platform 8, and a spring 12 is fixedly connected to the cross plate 11. The spring 12 One end away from the cross plate 11 is fixedly connected to the fixed block, and the support platform 8 includes a support rod 13 and a baffle 14. Two baffles 14 and two support rods 13 are provided. The two support rods 13 are symmetrically fixed on both sides of the conveyor belt 6. The two baffles 14 are respectively fixed on the two support rods 13. The screen 7 is slidably set between the two baffles 14. After the motor 3 is turned on, the screen 7 will reciprocate horizontally relative to the two baffles 14 under the drive of the lever 10 and the spring 12, and the regenerated sand particles will be reciprocated to speed up the screening process.

[0022] A brush plate 15 is slidably provided on the screen 7, and a cross bar 16 is fixedly installed on the two baffles 14. The brush plate 15 is also slidably connected to the cross bar 16. A handle 17 is fixedly installed on one end of the brush plate 15 close to the cross bar 16. When the screen 7 slides back and forth, the brush plate 15 will also slide back and forth with the screen 7 and cooperate with the screen 7. After the screening is completed, the staff pulls the brush plate 15 to slide on the screen 7 so that the unqualified particles on the screen 7 are pushed and gathered together.

[0023] A vertical plate 18 is fixedly provided at one end of the screen 7, and a rotating plate 19 is rotatably provided at the other end. A support assembly 20 for controlling the rotation angle of the rotating plate 19 is fixedly provided on the screen 7, and the output end of the support assembly 20 abuts against the end of the rotating plate 19 away from the screen 7. The support assembly 20 supports the rotating plate 19 to keep it in a vertical state or a rotated downward state. The support assembly 20 includes a mounting plate 21, a hydraulic rod 22 and a support block 23. The mounting plate 21 is fixedly provided on a side of the screen 7 close to the conveyor belt 6, the hydraulic rod 22 is fixedly installed on the mounting plate 21, and the support block 23 is fixedly provided on the output shaft of the hydraulic rod 22, and the support block 23 abuts against the rotating plate 19.

[0024] One end of the two baffles 14 close to the rotating plate 19 is fixedly connected with a vertical rod 24, and a placement plate 25 is fixedly connected between the two vertical rods 24. A receiving box 26 is slidably provided on the placement plate 25. The receiving box 26 is used to receive unqualified regenerated sand particles. When the receiving box 26 is full, the receiving box 26 can be slid away to reprocess the particles in the receiving box 26.

[0025] When the utility model is in use, the regenerated sand that needs to be screened is poured onto the screen 7, the motor 3 is started, the motor 3 controls the rotating roller 1 4 to rotate, and the rotating roller 1 4 drives the conveyor belt 6 and the rotating roller 2 5 to rotate, and at the same time, the lever 10 fixedly connected to the output shaft of the motor 3 rotates, and when the lever 10 rotates, the lever 10 contacts the connecting block 9, driving the connecting block 9 to slide relative to the baffle 14, and the connecting block 9 is fixedly connected to the screen 7, then the screen 7 is relative to the baffle 14. When the lever 10 rotates away from the connecting block 9, the spring 12 drives the connecting block 9 to return to the initial position, and waits for the next time when the lever 10 rotates and contacts the connecting block 9, and then drives the connecting block 9 to slide;

[0026] When the screening of the regenerated sand is completed, the qualified regenerated sand falls onto the conveyor belt 6 and is transported to the next process via the conveyor belt 6. The regenerated sand with larger particles is left on the screen 7. The hydraulic rod 22 is started, and the support block 23 fixedly connected to the top of the hydraulic rod 22 moves down, and the turn plate 19 rotates downward to cooperate with the receiving box 26. At this time, the staff pulls the handle 17 to make the brush plate 15 slide on the screen 7. The brush plate 15 pushes the large-particle regenerated sand on the screen 7 to the turn plate 19, and the large-particle regenerated sand rolls into the receiving box 26 through the turn plate 19, completing the collection and processing of the residual regenerated sand after screening.
