First side plates 5 are fixedly provided on both the front and rear sides of the top end of the first discharge plate 2. Second side plates 6 are fixedly provided on both the front and rear sides of the top end of the second discharge plate 3. A second adjustment groove 7 is opened on the outside of the first side plate 5. One end of the second side plate 6 extends into the inside of the second adjustment groove 7;

[0030] Four support legs 8 are respectively fixedly provided at the four corners of the bottom end of the dewatering screen main body 1. A support plate 9 is provided at the bottom of one end of the second discharge plate 3 away from the first discharge plate 2. The top end of the support plate 9 is hinged to the bottom end of the second discharge plate 3. A length adjustment component is provided between the support leg 8 and the support plate 9, and a height adjustment component is provided on the support leg 8.

[0031] The length adjustment component includes four first threaded rods 10 provided on the outside of two support legs 8 and the inside of the support plate 9. Two of the first threaded rods 10 are fixedly connected to the support plate 9. A threaded sleeve 11 is provided between the two first threaded rods 10 on both sides. One ends of the two first threaded rods 10 respectively extend into both ends of the threaded sleeve 11 and are threadedly connected to the threaded sleeve 11. A first turntable 14 is fixedly provided at the outer end of the threaded sleeve 11. A first synchronous pulley 12 is fixedly provided at the outer end of the threaded sleeve 11. The first synchronous pulley 12 is provided on one side of the first turntable 14. The two first synchronous pulleys 12 are connected by a first synchronous belt 13.

[0032] The height adjustment assembly includes a T-shaped chute 15 opened on one side of the support leg 8. Inside the T-shaped chute 15, there is a T-shaped slider 16. Two T-shaped sliders 16 are fixedly connected to another two first threaded rods 10. Inside the T-shaped chute 15, there is a second threaded rod 17. The top end of the second threaded rod 17 passes through the T-shaped slider 16 and is threadedly connected with the T-shaped slider 16. Both ends of the second threaded rod 17 are rotatably connected to the top end and the bottom end inside the T-shaped chute 15 through bearings. A second synchronous pulley 18 is fixedly provided at the bottom end of the second threaded rod 17. The two second synchronous pulleys 18 are connected by a second synchronous belt 19. Communication ports 20 are opened on the opposite sides of the two support legs 8. The second synchronous belt 19 passes through the inside of the communication port 20. A turntable groove 21 is opened on the bottom inner wall of the T-shaped chute 15. A second turntable 22 is fixedly provided on the outer side of the bottom end of the second threaded rod 17. The second turntable 22 is arranged inside the turntable groove 21. The second turntable 22 is arranged on top of the second synchronous pulley 18.

[0033] A first elastic band 23 is fixedly provided between the discharge end of the dewatering screen main body 1 and the top end of the first blanking plate 2. Second elastic bands 24 are fixedly provided between the dewatering screen main body 1 and the two first side plates 5.

[0034] Rotate the first turntable 14. The first turntable 14 drives a threaded sleeve 11 to rotate. The threaded sleeve 11 drives another threaded sleeve 11 to rotate through two first synchronous pulleys 12 and a first synchronous belt 13. Since the threaded sleeve 11 is threadedly connected to the first threaded rod 10, the two first threaded rods 10 extend outward as the threaded sleeve 11 rotates. The two first threaded rods 10 drive the support plate 9 to move outward. The support plate 9 drives the second blanking plate 3 to move outward. In this way, the total length of the first blanking plate 2 and the second blanking plate 3 can be adjusted.

[0035] Rotate the second turntable 22. The second turntable 22 drives a second threaded rod 17 to rotate. The second threaded rod 17 drives another second threaded rod 17 to rotate through two second synchronous pulleys 18 and a second synchronous belt 19. Since the second threaded rod 17 is threadedly connected to the T-shaped slider 16, the T-shaped slider 16 moves up and down inside the T-shaped chute 15 as the second threaded rod 17 rotates. The T-shaped slider 16 drives the first threaded rod 10 and the threaded sleeve 11 to move up and down. The first threaded rod 10 and the threaded sleeve 11 drive the bottom end of the second blanking plate 3 to move up and down. The second blanking plate 3 drives the first blanking plate 2 to rotate. In this way, the discharge height of the first blanking plate 2 and the second blanking plate 3 can be adjusted.

[0036] The utility model adjusts the total length and the discharging height of the first discharging plate 2 and the second discharging plate 3 through a length adjusting component and a height adjusting component. When there are errors in the installation position and the installation height of the subsequent conveying device of the dewatering screen, the length and the height of the discharging can be adjusted to adapt to the position of the conveying device, avoiding the situation of re-welding the discharging structure, and having relatively strong practicability. This embodiment specifically solves the problem existing in the prior art that in the actual use of the sand material dewatering screen, most of the discharging frames on the dewatering screen are directly welded to the main body and cannot adjust the discharging height and length. When there are some errors in the installation position and the installation height of the subsequent conveying device of the dewatering screen, the discharging height and length cannot be adapted, and at this time, it is necessary to re-weld the discharging frame, which is rather troublesome and the practicability is not strong enough.

[0037] Only some exemplary embodiments of the present utility model have been described by way of illustration. Undoubtedly, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present utility model. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present utility model.
