[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] The vibrating screen frame with self-cleaning function is a vibrating screening equipment that can automatically remove blocked materials on the screen.

[0025] See also Figure 1-Figure 4 As shown, this embodiment provides a vibrating screen frame with a self-cleaning function, including a base 1. In order to facilitate the removal of things in the mesh 11, the details are as follows: side plates 29 are fixedly connected to both sides of the inner surface of the upper side of the base 1, the end of a threaded rod 28 is rotatably connected to the interior of the side plate 29 on one side, the end of a sliding rod 281 is fixedly connected to the outer surface of the side plate 29, and the outer surface of the sliding rod 281 is slidably connected to a moving block 24, and the outer surface of the side plate 29 on the other side is fixedly connected to a cylindrical rod 291, the outer surface of the threaded rod 28 is threadedly connected to the interior of the moving block 24, and the outer surface of the cylindrical rod 291 is slidably connected to another moving block. The movable block 24 is rotatably connected to a rotating rod 25 inside the movable block 24, and the end of the rotating rod 25 is fixedly connected to the mounting block 2. A slide groove 23 is provided on the inner surface of the mounting block 2, and a slider 21 is slidably connected to the inner wall of the slide groove 23. The inner surface of the slider 21 is fixedly connected to the mesh 11, and the mounting block 2 rotates with the rotating rod 25 on the rotating rod 25. However, in the existing vibrating screen frame with a self-cleaning function, during use, more things that cannot be screened out in the screen accumulate and fall everywhere. If the things in the screen need to be cleaned out, they need to be shoveled out with something, or the screen needs to be taken down and poured out, which is very cumbersome.

[0026] The improvement of this embodiment is that:

[0027] First, the first motor 282 rotates to drive the threaded rod 28 to rotate, and then the threaded rod 28 rotates to drive the moving block 24 to move, and then the moving block 24 moves to drive the rotating rod 25, the mounting block 2, the slider 21 and the mesh screen 11 to move, and the handle 27 is rotated to drive the rotating rod 25, the mounting block 2, the slider 21 and the mesh screen 11 to rotate, so that the mesh screen 11 can be moved to the other side and flipped over, so that the things in the mesh screen 11 will not be mixed with the things sieved out, and the things in the mesh screen 11 can be quickly taken out, thereby improving the screening efficiency of the mesh screen 11.

[0028] In order to prevent the slider 21 from sliding randomly when the mesh 11 rotates, the end of a spring 22 is fixedly connected to the top of the slider 21, and the other end of the spring 22 is fixedly connected to the inner surface of the slide groove 23. First, when the slider 21 slides, the spring 22 rebounds, and then the rebound of the spring 22 drives the slider 21 not to slide easily, so that the slider 21 does not slide randomly when the mesh 11 rotates.

[0029] In order to prevent the rotating rod 25 from rotating at will, a rotating handle 27 is fixedly connected to the other end of the rotating rod 25, a hole groove 251 is opened on the outer surface of the rotating rod 25, and the end of the U-shaped block 26 is inserted into the front of the moving block 24, and the other end of the U-shaped block 26 is inserted into the inside of the hole groove 251. First, the moving block 24 fixes the U-shaped block 26, and then the U-shaped block 26 fixes the rotating rod 25, so that the rotating rod 25 does not rotate at will.

[0030] Secondly, in order to facilitate the rotation of the threaded rod 28, a first motor 282 is fixedly connected to the front of the side panel 29. The end of the output shaft of the first motor 282 extends into the interior of the side panel 29 and is fixedly connected to the end of the threaded rod 28. First, the first motor 282 rotates to drive the threaded rod 28 to rotate, and then the threaded rod 28 is rotated conveniently.

[0031] Taking into account that some things are stuck on the mesh screen 11 and cannot fall down when the mesh screen 11 is flipped over, a mounting plate 31 is fixedly connected to the bottom of the mounting block 2, and a rotating shaft 32 is rotatably connected inside the mounting plate 31. The outer surface of the rotating shaft 32 is fixedly connected to the cam 3, and the outer surface of the mounting plate 31 is fixedly connected to the end of the second motor 33. The end of the output shaft of the second motor 33 extends into the interior of the mounting plate 31 and is fixedly connected to the end of the rotating shaft 32. First, the second motor 33 rotates to drive the rotating shaft 32 to rotate, and then the rotating shaft 32 rotates to drive the cam 3 to rotate, and then the cam 3 rotates and hits the mesh screen 11, so that the mesh screen 11 vibrates to shake off the things stuck on the mesh screen 11, so that the things stuck on the mesh screen 11 can fall down when the mesh screen 11 is flipped over.

[0032] In summary, the working principle of this solution is as follows:

[0033] When the mesh screen 11 is screening things, the first motor 282 is connected to the power supply, and the threaded rod 28 is driven to rotate by the rotation of the first motor 282, and the moving block 24 is moved by the rotation of the threaded rod 28, and the rotating handle 27, the rotating rod 25, the mounting block 2, the slider 21 and the mesh screen 11 are moved by the movement of the moving block 24, and the other moving block 24 slides to one side on the cylindrical rod 291, and the second motor 33 is connected to the power supply, and the rotating shaft 32 is driven to rotate by the rotation of the second motor 33, and the cam 3 is driven to rotate by the rotation of the rotating shaft 32, and the impact on the mesh screen 11 is carried out by the rotation of the cam 3 for screening. When it is necessary to clean the things in the base 1, the mesh screen 11 is moved to the other side by the rotation of the threaded rod 28 to manually pull out the U-shaped block 26 When the mesh screen 11 is tilted or turned over, the slider 21 will slide due to the influence of gravity, but the rebound of the spring 22 will make it difficult for the slider 21 to slide. By knocking on the mesh screen 11 through the cam 3, it is easier to shake off the things stuck on the mesh screen 11. After the things come out, the mesh screen 11 is manually turned flat, and the handheld U-shaped block 26 is inserted into the hole slot 251 and the moving block 24, so that the mesh screen 11 will not rotate and cause things to fall out when in use, so that the things in the mesh screen 11 are easy to take out and clean.
