[0001] The utility model relates to the technical field of vibrating screens, in particular to a self-centering vibrating screen with high stability. Background Art

[0002] During long-term use, the holes of the screen plate of the existing vibrating screen will gradually be clogged with particulate matter, which will affect the operating effect of the vibrating screen and thus reduce the screening efficiency. The existing manual cleaning method is not only time-consuming and labor-intensive, but also when manual cleaning is performed, the materials stuck in the holes will be more firmly stuck in the holes of the screen plate due to long-term vibration and collision of the top materials, increasing the cleaning burden.

[0003] Therefore, the present application provides a high-stability self-centering vibrating screen to meet the needs. Utility Model Content

[0004] The purpose of the present application is to provide a highly stable self-centering vibrating screen, which aims to solve the problem of materials stuck in the holes, where long-term vibration and collision of top materials cause part of the materials to be more firmly stuck in the holes of the screen plate, increasing the cleaning burden.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a self-centering vibrating screen with high stability, comprising a vibrating screen body, a sieve plate is provided on the vibrating screen body, a material receiving plate is provided on the bottom surface of the sieve plate, an anti-blocking mechanism is provided below the material receiving plate, and a driving mechanism is provided on the outer wall of the vibrating screen body, and the driving mechanism is connected to the anti-blocking mechanism;

The dredging plate is slidably connected to the vibrating screen body, and a plug is provided on the top surface of the dredging plate. The plug and the hole are adapted to each other. A bottom plate is installed on the inner bottom surface of the vibrating screen body. The bottom plate and the dredging plate are connected by an elastic member, and the holes correspond to the positions of the holes on the screen plate and the sizes match. When the vibrating screen body is working, the dredging plate moves synchronously with the vibrating screen body, so that the plug on the dredging plate and the screen plate are in a relatively static state. Therefore, driven by the anti-blocking mechanism and the driving mechanism, when the dredging plate is reciprocating up and down, its plug and the hole on the screen plate are in a relatively static state. The plug is inserted into the hole to perform an anti-blocking dredging on the screen plate to avoid blockage of the screen plate and affect work efficiency.

[0007] Preferably, the elastic member is a spring or an elastic sheet.

[0008] Preferably, the driving mechanism includes a rack, a mounting plate and a slide plate, a rotating shaft, a driving gear, a gear set, and a driving motor. A perforation is provided on the outer wall of the vibrating screen body, and a mounting plate is fixed at the position of the perforation by bolts. There are two groups of perforations, which are symmetrically arranged. The two groups of mounting plates are connected by a slide plate. The rack is provided on the bottom surface of the dredging plate, and a slide groove is provided on the rack. The slide plate is located in the slide groove. A rotating shaft is rotatably connected on the mounting plate, and a driving gear is provided on the rotating shaft. The driving gear and the rack are meshed with each other.

[0009] Preferably, the driving gear is a half gear. Without changing the rotation direction of the driving motor, the rack can efficiently reciprocate, the rack is limited in the tooth segment of the half gear, and the spring is stored; when the driving gear passes through the tooth segment of the half gear and moves to the toothless segment, the limit on the rack is released, the elastic force of the spring is released, and the plug is inserted into the hole of the screen plate to clear the screen plate.

[0010] Preferably, the gear set includes a first bevel gear and a second bevel gear, the first bevel gear is arranged on the end face of the rotating shaft, the second bevel gear is arranged on the driving shaft of the driving motor, and the first bevel gear and the second bevel gear are meshed with each other.

[0011] Preferably, a fixing block for enhancing the rotation stability of the rotating shaft is provided on the outer wall of the slide plate, and the rotating shaft is rotatably connected to the fixing block.

[0012] In summary, the technical effects and advantages of the utility model are:

[0013] In the utility model, when the vibrating screen body is working, the dredging plate moves synchronously with the vibrating screen body, so that the plug on the dredging plate and the screen plate are in a relatively static state. Therefore, driven by the anti-blocking mechanism and the driving mechanism, when the dredging plate performs up and down reciprocating motion, its plug and the hole on the screen plate are in a relatively static state. The plug is inserted into the hole to perform an anti-blocking dredging on the screen plate to avoid blockage of the screen plate and affect the work efficiency.

[0014] In the utility model, the driving gear is a half gear, and when the rotation direction of the driving motor remains unchanged, the dredging plate is made to move up and down regularly in cooperation with a spring, thereby preventing the screen plate from being blocked.

[0015] The plug is matched with the hole on the receiving plate. When the dredging plate moves to the bottom, the top surface of the plug is flush with the top surface of the receiving plate, so that the receiving plate can transport materials. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Anti-blocking mechanism: a dredging plate 4 is slidably connected to the lower side of the receiving plate 3 (the inner top surface of the vibrating screen body 1), a plug 41 is provided on the top surface of the dredging plate 4, the plug 41 corresponds one to one with the holes of the receiving plate 3, and a bottom plate 5 is provided on the inner bottom surface of the vibrating screen body 1, the bottom plate 5 is connected to the dredging plate 4 through springs 6, three groups of bottom plates 5 are provided, and five groups of springs 6 are provided on the top surface of each group of bottom plates 5; through the structural description of this paragraph, when the anti-blocking mechanism is controlled to descend driven by the driving mechanism, the spring 6 is squeezed, and after the squeezing state of the spring 6 is released, the elastic force of the spring 6 is released, so that the dredging plate 4 is lifted up, the plug 41 slides out of the hole of the receiving plate 3, and is inserted into the hole of the screen plate 2, so as to achieve the purpose of dredging the screen plate 2.

[0028] Driving mechanism: A through hole connecting the interior is provided on the outer wall of the vibration screen body 1, and a mounting plate 8 is fixed at the position of the through hole by bolts, and the two sets of mounting plates 8 are connected by a slide plate 9; two sets of racks 7 are installed on the bottom surface of the dredging plate 4, and a slide groove 71 is provided on the rack 7, and the slide plate 9 is located in the slide groove 71. The structural design here provides power transfer for the reciprocating motion of the dredging plate 4. A rotating shaft 11 is provided on the front side of the slide plate 9, and the rotating shaft 11 is rotatably connected to the mounting plate 8, and a driving gear 12 is provided on the rotating shaft 11. The driving gear 12 is a half gear. When the driving gear 12 is driven, the driving gear 12 cooperates with the rack 7 to move the rack 7 downward, squeeze the spring 6, and store energy in the spring 6. Then, when passing through the toothless area, the spring 6 is released to realize the reciprocating motion of the dredging plate 4; a driving motor 15 is installed on the outer wall of the vibration screen body 1, and the driving motor 15 is connected to the rotating shaft 11 through a gear group to control the rotation of the rotating shaft 11.

[0029] Gear set: The first bevel gear 13 is coaxially connected to the rotating shaft 11, and the second bevel gear 14 is arranged on the driving shaft of the driving motor 15. The first bevel gear 13 and the second bevel gear 14 are meshed with each other to realize power steering.

[0030] Two groups of fixing blocks 10 are arranged on the outer wall of the slide plate 9, and cooperate with the mounting plate 8 to reinforce the rotating shaft 11 at multiple points to improve the rotation stability.

[0031] The working principle of the utility model is as follows: the driving motor 15 is started, and the driving shaft of the driving motor 15 drives the meshing No. 1 bevel gear 13 to rotate through the No. 2 bevel gear 14, and then the No. 1 bevel gear 13 drives the rotating shaft 11 to rotate on the mounting plate 8, and the rotating rotating shaft 11 drives the driving gear 12 to rotate, and the teeth on the driving gear 12 mesh with the rack 7, so that the rack 7 slides vertically on the slide plate 9 through the slide groove 71. During this process, the rack 7 drives the dredging plate 4 to move downward and squeezes the spring 6, so that the spring 6 is in an energy storage state (in this state, the top surface of the plug 41 is flush with the top surface of the receiving plate 3). Subsequently, after the tooth segment of the driving gear 12 leaves the rack 7, its toothless segment releases the limit on the rack 7. The spring 6 releases its elastic force at this time, causing the dredging plate 4 to move upward, and the plug 41 slides in the hole of the receiving plate 3 and is inserted into the hole of the sieve plate 2 to dredge the sieve plate 2 to avoid blockage.
