[0012] Compared with the prior art, the beneficial effects of this utility model are: this clay block vibrating screen that avoids screen hole clogging is reasonable and has the following advantages:

[0013] (1) This vibrating screen effectively solves the problem of easy clogging in traditional screening equipment through the innovative bidirectional tilting structure and the synergistic effect of the cleaning mechanism, thereby improving screening efficiency and extending the service life of the equipment. When the motor drives the paddle to swing, it will alternately push the two sets of sliding plates to move up and down, so that the screen plate will tilt periodically left and right. This dynamic tilting design produces a triple anti-clogging mechanism: First, the tilting action causes the material to slide on the screen plate, using gravity and inertia to decompose the agglomerated material; Second, the triangular cleaning block and the tilted screen plate form a wedge-shaped scraping surface, and its sharp edge can penetrate into the screen hole to scrape off the embedded particles; Finally, the inclined structure of the fixed frame guides the impurities to slide to both sides to avoid secondary accumulation. Compared with the traditional linear vibrating screen This design improves the screening efficiency of clay blocks. In addition, the servo motor controls the tilting frequency, which can prevent material splashing caused by excessive tilting and ensure sufficient cleaning action, achieving the best balance between anti-clogging and screening efficiency. The cooperation between the spring and the fixed plate in the reset assembly ensures the rapid reset of the sliding plate. The elastic deformation of the spring not only buffers the mechanical impact, but also stores some kinetic energy for reverse movement, forming an energy-saving reciprocating mechanism. The sliding connection between the sliding plate and the inner wall of the box reduces friction loss and further improves energy efficiency. In addition, the mounting rod and the mounting frame are connected by a rotating connection of the connecting block and the connecting frame, which transforms the vertical movement of the sliding plate into multi-angle tilting of the screen plate, simplifying the power system structure.

[0024] Example 1:

[0025] A clay block vibrating screen for preventing screen hole clogging includes a housing 100, a screen plate 101 installed inside the housing 100, a collection assembly inside the housing 100, mounting frames 200 symmetrically fitted on the outer surface of the screen plate 101, the mounting frames 200 and the screen plate 101 connected by a sliding assembly, a connecting frame 203 at the bottom of the mounting frame 200, a mounting rod 204 below the mounting frame 200, a connecting block 205 on the mounting rod 204 that cooperates with the connecting frame 203 and is rotatably disposed within the connecting frame 203, a sliding plate 206 fixedly mounted at the bottom of the mounting rod 204 and slidably connected to the inner wall of the housing 100, a toggle mechanism inside the housing 100 for driving two sets of sliding plates 206 to move up and down, a reset assembly installed on the sliding plate 206, and a cleaning mechanism between the two sets of mounting frames 200.

[0026] The collection assembly includes a collection box 102 disposed inside the housing 100, and the collection box 102 is located directly below the sieve plate 101.

[0027] The sliding assembly includes symmetrically formed grooves 202 on the outer wall of the sieve plate 101, and symmetrically formed sliders 201 that cooperate with the grooves 202 on the inner wall of the mounting frame 200.

[0028] The reset assembly includes a fixing plate 207 symmetrically fixed to the inner wall of the housing 100. The bottom end of the fixing plate 207 is connected to one end of a spring 208, and the other end of the spring 208 is connected to a sliding plate 206.

[0029] The actuating mechanism includes a toggle block 407 located between two sets of sliding plates 206. The rear end of the housing 100 is provided with a mounting box 400, and the mounting box 400 is provided with a driving component that drives the toggle block 407 to swing left and right.

[0030] The drive assembly includes a mounting frame 401 disposed in the mounting box 400, a motor 402 mounted on the mounting frame 401, the output end of the motor 402 being connected to a first bevel gear 403, a second bevel gear 404 meshing with the first bevel gear 403 on one side, a rotating rod 405 disposed in the middle of the second bevel gear 404, and the rotating rod 405 being disposed in a lever block 407, the end of the rotating rod 405 away from the second bevel gear 404 being connected to a connecting plate 406, and the connecting plate 406 being located on the collection box 102.

[0031] The cleaning mechanism includes a fixed frame 300 fixed inside the housing 100, and the fixed frame 300 is located outside the sieve plate 101. The fixed frame 300 is provided with a cleaning block 301, and the cleaning block 301 has a triangular cross section and is in contact with the sieve plate 101.

[0032] Working principle: During use, the material to be sieved is placed into the sieve plate 101. Impurities in the material will be filtered through the sieve holes on the sieve plate 101 and finally fall into the collection box 102. During the sieving process, the sieve holes may gradually become blocked. At this time, the sliding plate 206 can be moved up and down alternately by driving the actuating mechanism, thereby tilting the sieve plate 101. This, together with the cleaning mechanism, prevents blockage. The motor 402 is started to drive the first bevel gear 403 to rotate. The rotation of the first bevel gear 403 drives the second bevel gear 404 meshing with it on one side. The rotation drives the rotating rod 405 to rotate, causing the lever 407, which is fixedly sleeved on the outer surface of the rotating rod 405, to swing. It should be noted that the motor 402 here is a servo motor, which drives the shaft to rotate forward and reverse and controls the speed. When the drive assembly drives the lever 407 to rotate slowly to one side, when the lever 407 touches the sliding plate 206 on one side, it will cause the sliding plate 206 to move upward. The fixed plate 207 also limits the maximum sliding distance of the sliding plate 206, preventing the lever 407 from exceeding the sliding plate 206. The mounting rod 204 and the mounting frame 200 are rotatably connected via the connecting frame 203 and the connecting block 205, and the mounting frame 200 and the screen plate 101 are slidably connected via the slider 201 and the sliding groove 202. Therefore, as one set of sliding plates 206 moves upward, the screen plate 101 tilts. When the screen plate 101 tilts, it slides within the mounting frame 200, contacting the cleaning block 301. This causes the cleaning block 301 to scrape material from the screen plate 101, preventing screen hole blockage. Since the cleaning block 301 has a triangular cross-section, it... Impurities falling from the sieve plate 101 fall into the fixed frame 300. Due to the design of the cleaning block 301, it slides down from both sides of the slope to prevent impurities from accumulating in the fixed frame 300. When the push block 407 reverses, the push block 407 moves away from the sliding plate 206. The sliding plate 206 is reset under the action of the spring 208. At the same time, the push block 407 rotates to the other side and contacts the other side of the sliding plate 206, thereby causing the sieve plate 101 to tilt in the opposite direction, so that the cleaning block 301 cleans the other half. This method increases the screening efficiency by driving the sieve plate 101 to tilt back and forth.
