Description

Technical Field

[0001] The utility model relates to the technical field of vibrating screens, in particular to a sealing structure for a vibrating screen plate. Background Art

[0002] The vibrating screen operates by utilizing the reciprocating vibration generated by the vibrator. The upper rotating weight of the vibrator causes the screen surface to produce a planar gyratory vibration, while the lower rotating weight causes the screen surface to produce a conical gyratory vibration. The combined effect of these two causes the screen surface to produce a complex gyratory vibration.

[0003] When the existing vibrating screen is in use, a gap will be left between the screen plate body and the hollow vibrating screen side plate during installation. This gap may cause coarse particles on the screen plate body to fall under the screen, reducing the screening effect. Therefore, we propose a vibrating screen screen plate sealing structure.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] Reference Figure 1-Figure 3 A vibrating screen plate sealing structure includes a screen plate body 3, and fixed plates 4 are provided on both sides of the screen plate body 3 at both ends. The same hollow vibrating screen side plate 1 is fixedly installed on the two fixed plates 4 at one end of the screen plate body 3, and sealing strips 2 are provided between the two hollow vibrating screen side plates 1 and the screen plate body 3. Multiple mounting components are provided on the two hollow vibrating screen side plates 1.

[0020] The mounting assembly includes a mounting block 12 fixedly mounted on the inner wall of the side plate 1 of the hollow vibrating screen away from the screen plate body 3, a threaded rod 14 is rotatably connected between the mounting block 12 and the inner top of the hollow vibrating screen side plate 1, a second block 13 is threadedly sleeved on the threaded rod 14, a guide rod 10 is fixedly connected between the inner walls of the two sides of the hollow vibrating screen side plate 1, a first block 9 is provided on the guide rod 10, a connecting rod 11 is provided between the first block 9 and the second block 13, the first block 9 and the second block 13 are rotatably connected to the two ends of the first block 9 respectively, and the hollow vibrating screen is fixedly connected to the inner wall of the hollow vibrating screen side plate 1. A circular hole 7 is provided on one side wall of the sieve side plate 1 close to the sieve plate main body 3, and an insertion rod 8 is fixedly installed on the side wall of the first block 9 close to the sieve plate main body 3. The first block 9 is located below the mounting block 12, and the insertion rod 8 is adapted to the circular hole 7. A plurality of insertion holes 6 are provided on the side of the two sealing strips 2 away from the sieve plate main body 3. The diameters of the plurality of insertion holes 6 are the same as the diameters of the plurality of circular holes 7. Teeth are provided on the two sealing strips 2, and one end of the threaded rod 14 passes through the inner top of the hollow vibrating screen side plate 1 and is fixedly installed with a knob 5 located outside the hollow vibrating screen side plate 1.

[0021] When the second block 13 moves downward, the first block 9 is caused to slide in the direction away from the threaded rod 14 by setting the connecting rod 11, so that the plug rod 8 passes through the circular hole 7 and is inserted into the plug hole 6. In this way, the sealing strip 2 can be fixed. Since a gap will be left between the sieve plate body 3 and the hollow vibrating screen side plate 1 when the sieve plate body 3 is installed, this gap may cause the coarse particles on the sieve plate body 3 to fall under the sieve, reducing the screening effect. The teeth on the sealing strip 2 cooperate with the sieve plate body 3 to improve the sealing effect, and at the same time, it plays a role in fixing the sealing strip 2 to prevent it from falling off. By turning the knob 5, the threaded rod 14 is rotated in the other direction, so that the plug rod 8 can be moved away from the plug hole 6, so that the sealing strip 2 can be removed.

[0022] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
