[0002] The sieve plate is also called a porous plate. It has good wear resistance, long service life, good moisture resistance and wear resistance. It is suitable for machinery such as ore washing, screening, grading, slag removal, mud removal, and dehydration. The sieve plate is a punching sieve plate with various hole types such as rectangular, square, round, herringbone, rod, narrow hole, rectangular, flower plate, oblong hole, triangular hole, square hole, plum blossom hole, shell hole, fish scale hole, etc. The sieve plate is an important working part of the screening machinery to complete the screening process. Each screening machine must select a sieve plate that meets its working requirements according to the different materials. The traditional sieve plate is mostly a flat plate with evenly distributed sieve holes on the upper surface. It has a simple structure and is easy to make. It can also achieve the purpose of screening. However, the traditional sieve plate cannot realize multi-stage screening of materials, and it is not convenient to screen out materials of different specifications at the same time. The screening operation efficiency is low and the performance is single. For this reason, we propose a rubber wear-resistant vibrating sieve plate. Utility Model Content

The tops of the plurality of conical plugs 7 in the same horizontal row are fixedly connected with the same cross bar 8. The two partitions 2 are provided with limited slots 9, and the two limited slots 9 are separated from each other by a lifting plate 10. One end of the plurality of cross bars 8 distributed up and down respectively penetrates the inner cavity of the adjacent limited slots 9 and is fixedly connected to the adjacent lifting plate 10. The two lifting plates 10 are provided with There is a threaded hole, and the inner cavity of the threaded hole is threadedly connected with a threaded rod 11 adapted thereto. Bearings are fixedly connected to the two horizontal plates 3, and the top ends of the two threaded rods 11 respectively penetrate the inner cavities of adjacent bearings and are fixedly connected with hand-cranked wheels 12. By turning the hand-cranked wheels 12, the threaded rods 11 can be driven to rotate, and the height of the lifting plate 10 can be adjusted. The movement of the lifting plate 10 can adjust the size of the gap between the conical plug 7 and the adjacent leakage hole 6 to achieve the purpose of adjusting the screening particle size, thereby improving the practicality of the use of the sieve plate 5, and the lifting plate 10 is away from One side of the limiting groove 9 is fixedly connected to a limiting plate 13, and a limiting rod 14 is slidably passed through the limiting plate 13, and the top of the limiting rod 14 is fixedly connected to the bottom of the adjacent horizontal plate 3. The limiting plate 13 can slide on the limiting rod 14 to limit the vertical position of the lifting plate 10, thereby improving the stability and smoothness of the lifting and lowering of the lifting plate 10. Layered plates 4 are fitted on the left and right sides of the bottom of the two sieve plates 5, and the layered plates 4 are fixedly connected to the adjacent partition plates 2, which can support the sieve plates 5 in the vertical direction, thereby maintaining the horizontal state of the sieve plates 5.

[0021] A fixing hole 16 is provided on the sieve plate 5 near the front side, and a fixing plate 17 is provided on one side of the sieve plate 5. The fixing plate 17 is fixedly connected to the front side wall of the U-shaped base 1, and a T-shaped rod 18 compatible with the fixing hole 16 is slidably penetrated through the fixing plate 17. The longer end of the T-shaped structure of the T-shaped rod 18 penetrates the inner cavity of the fixing hole 16, and a reset spring 19 is sleeved on the outer wall of the T-shaped rod 18, and the two ends of the reset spring 19 are respectively fixedly connected to the T-shaped rod 18 and the fixing plate 17.

[0024] Working principle: When the utility model is in use, the U-shaped base 1 is installed on the screening machine by using screws and oblong holes 22, and the material to be screened is first thrown onto the upper screen plate 5, and the material can be screened by setting the leakage hole 6. When the material needs to be screened at multiple levels, the right hand-cranked wheel 12 can be rotated to drive the threaded rod 11 to rotate, and the rotation of the threaded rod 11 drives the right lifting plate 10 to move vertically downward. The downward movement of the right lifting plate 10 can drive the several conical plugs 7 below to move downward through the cross bar 8, thereby reducing the gap between the leakage hole 6 and the leakage hole 6, so that the pores of the leakage hole 6 on the lower screen plate 5 are smaller than the pores of the upper leakage hole 6, thereby realizing multi-level screening of the material. In addition, the left hand-cranked wheel 12 can be rotated to drive the threaded rod 11 to rotate, and drive the left lifting plate 10 to move downward, so as to reduce the pores of the leakage hole 6 on the upper screen plate 5. The gap size can be adjusted, and the pore size of the lower leakage hole 6 is always kept smaller than the upper pore size, so that the material can be screened at more levels. When the screened material falls on the upper surface of the guide plate 15, the two sides of the guide plate 15 can be tilted to guide the material to the left and right sides of the U-shaped base 1, so as to facilitate the staff to collect the material. In addition, by arranging wear-resistant rubber pads 20 on the surfaces of the sieve plate 5 and the guide plate 15, the friction between the sieve plate 5 and the guide plate 15 and the material can be reduced during the material screening process, thereby improving the service life of the sieve plate 5 and the guide plate 15. When it is necessary to further expand the screening particle size of the material, the T-shaped rod 18 can be pulled to overcome the resistance of the reset spring 19 and move it, and the T-shaped rod 18 can be removed from the inner cavity of the fixing hole 16, so that the sieve plate 5 can be removed from the U-shaped base 1, thereby improving the convenience of disassembly and replacement of the sieve plate 5.
