The bottom end of the outer surface of the push rod is sleeved with a second spring, and the bottom end of the push rod is provided with a limiting plate. The second spring is located between the upper end of the limiting plate and the top wall of the cylinder to provide impact buffering.

[0010] Furthermore, the vibration mechanism also includes a rotating shaft, a turntable, a rotating column and a connecting rod.

[0015] 1. When the rotating column on the turntable changes from the lowest point to the highest point, the cylinder drives the push rod to push up, and the push rod hits the bottom end of the screen frame. Then, as the rotating column rotates further and rises, the second spring is moderately compressed to the maximum extent (to avoid direct hard impact and reduce the service life of accessories). Then, the screen frame is lifted by the push rod, the first spring is stretched, and the slide column slides in the slide hole at the top of the leg. When the rotating column on the turntable changes from the highest point to the lowest point, the cylinder moves down. First, the second spring returns to normal, and then drives the push rod to fall. The screen moves down by the deadweight of the tailings sand it carries. As the turntable rotates at high speed, the treated tailings sand is dehydrated during the reciprocating process, which can increase the vibration amplitude of the screen and make the tailings sand dehydration effect faster.

[0016] 2. Slide the sealing plate upwards, pull out the screen, insert the new screen and slide the sealing plate downwards to quickly replace the screen. The screen can be replaced quickly and conveniently to better meet the dehydration effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Vibration mechanism 5: It includes a slide post 509, a spring 1 510 and a support block 511. The slide holes at the top of the support legs 1 are respectively connected with slide posts 509 in a sliding manner. The tops of the slide posts 509 are respectively provided with support blocks 511. Springs 1 510 are respectively sleeved on the outer surfaces of the slide posts 509. Springs 1 510 are respectively located between the bottom ends of the support blocks 511 and the upper surfaces of the support legs 1. The inner sides of the support blocks 511 are fixedly connected to the outer side surfaces of a screen frame 6 through support columns. The vibration mechanism 5 also includes a cylinder 505, a slide 506, a push rod 507 and a spring 2 508. The slide 506 is respectively arranged on the front and rear sides of the bottom of the screen frame 6. The interior of the slide 506 is slidably connected to the cylinder 505. The interior of the cylinder 505 is slidably connected to the push rod 507. The bottom end of the outer surface of 507 is sleeved with a spring 2 508, and the bottom end of the top rod 507 is provided with a limit plate. The spring 2 508 is located between the upper end of the limit plate and the top wall of the cylinder 505. The vibration mechanism 5 also includes a rotating shaft 501, a turntable 502, a rotating column 503 and a connecting rod 504. The left and right inner walls of the adjustment seat 4 are respectively rotatably connected with the rotating shaft 501. The end of the rotating shaft 501 close to the center of the adjustment seat 4 is provided with a turntable 502. A rotating column 503 is respectively provided between the eccentric points of the two turntables 502 located in the same adjustment seat 4. The outside of the rotating column 503 is respectively rotatably connected with the connecting rod 504. The top end of the connecting rod 504 is rotatably connected to the bottom end of the vertically adjacent cylinder 505. The vibration mechanism 5 also includes a motor 512. 512 are respectively arranged on the right side of the adjustment seat 4, and the output shaft of the motor 512 is fixedly connected to the right end of the right rotating shaft 501, and the input end of the motor 512 is respectively electrically connected to the output end of the single-chip computer 2. When the tailings sand needs to be dehydrated after the sand making and sand washing process, the treated sand is first poured onto the screen 8, and the motor 512 starts to run. The output shaft of the motor 512 will drive the right rotating shaft 501 to start rotating, and drive the turntable 502 to start rotating, and will drive the rotating column 503 to start rotating with the rotating shaft 501 as the center. The bottom end of the connecting rod 504 rotates and tilts with the rotating column 503, and then the connecting rod 504 and the bottom end of the cylinder 505 rotate relative to each other, so that the cylinder 505 slides inside the slide 506. When the rotating column 503 on the turntable 502 03 changes from the lowest point to the highest point, the cylinder 505 drives the push rod 507 to push up, and the push rod 507 hits the bottom end of the screen frame 6. Then, as the rotating column 503 rotates and rises further, the spring 2 508 is moderately compressed to the maximum extent (to avoid direct hard impact and reduce the service life of accessories), and then the screen frame 6 is lifted by the push rod 507, the spring 1 510 is stretched, and the sliding column 509 slides in the sliding hole at the top of the support leg 1. When the rotating column 503 on the turntable 502 changes from the highest point to the lowest point, the cylinder 505 moves down. First, the spring 2 508 returns to normal, and then drives the push rod 507 to fall. The screen 8 moves down by the dead weight of the tailings sand it carries. As the turntable 502 rotates at high speed, the treated tailings sand is dehydrated during the reciprocating process.

[0024] The working principle of a vibrating dewatering screen for sand making and washing based on tailings sand provided by the present invention is as follows: when the tailings sand needs to be dehydrated after the sand making and washing treatment, the treated tailings sand is first poured onto the screen 8, and the motor 512 starts to run through the regulation of the single chip microcomputer 2. The output shaft of the motor 512 will drive the rotating shaft 501 on the right to start rotating, and drive the turntable 502 to start rotating, which will drive the rotating column 503 to start rotating with the rotating shaft 501 as the center of the circle. The bottom end of the connecting rod 504 rotates and tilts with the rotating column 503, and then the connecting rod 504 and the bottom end of the cylinder 505 rotate relative to each other, so that the cylinder 505 slides inside the slide 506. When the rotating column 503 on the turntable 502 changes from the lowest point to the highest point, the cylinder 505 drives the push rod 507 to push up, and the push rod 507 hits the bottom end of the screen frame 6. As the rotating column 503 rotates and rises further, spring 2 508 is moderately compressed to the maximum extent (to avoid direct hard impact and reduce the service life of accessories), and then the screen frame 6 is lifted by the top rod 507, spring 1 510 is stretched, and the sliding column 509 slides in the sliding hole at the top of the support leg 1. When the rotating column 503 on the turntable 502 changes from the highest point to the lowest point, the cylinder 505 moves down. First, spring 2 508 returns to normal, and then drives the top rod 507 to fall. The screen 8 moves down by the weight of the tailings sand it carries. As the turntable 502 rotates at high speed, the processed tailings sand is dehydrated during the reciprocating process. When the screen 8 needs maintenance after long-term use, the cover plate 9 is slid upward, the screen 8 is pulled out, and the new screen 8 is inserted into the downward sliding cover plate 9. The screen 8 is quickly replaced, thereby achieving the required dehydration effect.
