Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 2 and Figure 4 This utility model provides an embodiment of a self-cleaning vibrating filter screen, including a base 1 designed to provide good support. A vibration mechanism 2 is mounted on the top of the base 1. The vibration mechanism 2 includes multiple guide columns 21 designed to provide good guidance. The bottoms of the guide columns 21 are fixedly connected to the top of the base 1. Vibration springs 22 are respectively sleeved on the outside of the guide columns 21. The support of the guide columns 21 prevents the vibration springs 22 from shifting during processing. A vibrator 23 is fixedly connected to the bottom of a support plate 3, driven by an electric power source to generate vibration energy, causing the support plate 3 to vibrate. The vibrator 23 is located on an adjacent side of the guide columns 21. The top of the vibration mechanism 2 is fixedly connected to... The support plate 3 is designed to provide good support capacity. The support plate 3 has a reciprocating mechanism 4 inside. The filter plate 5 is fixedly connected inside the support plate 3. By placing materials on the top of the filter plate 5, the materials can be screened. The filter plate 5 has a fixing mechanism 7 inside. The support plate 3 has a discharge mechanism 6 outside. The discharge mechanism 6 includes an inclined plate 61. The inclined plate 61 is designed to transport and collect the screened solid particles. The inclined plate 61 is fixedly connected to the outside of the support plate 3, that is, to the outside side of the filter plate 5. The support plate 3 has a discharge plate 62 fixedly connected to the outside. The discharge plate 62 is designed to collect the screened materials. The discharge plate 62 is located at the bottom of the inclined plate 61.

[0034] The reciprocating mechanism 4 includes a top plate 41, designed to provide good support. The bottom of the top plate 41 is fixedly connected to the top of the support plate 3. A motor 42 is fixedly connected to the top of the top plate 41, designed to provide good driving capability. A rotating rod 48 is fixedly connected to the output end of the motor 42. The rotation of the motor 42 drives the rotating rod 48 to rotate. A connecting rod 43 is rotatably connected to the outer side of the rotating rod 48, designed to provide good rotation capability. When the rotating rod 48 rotates, the connecting rod 43 can rotate accordingly. A support rod 46 is rotatably connected to the bottom of the connecting rod 43, designed to provide good connection capability. The rotation of the connecting rod 43 by the rotating rod 48 drives the support rod 46 to move accordingly. Sliding components are slidably connected to the outer sides of the support rod 46. The sliding components include two sliders 45, designed to provide good... The sliding capability is achieved by fixing two sliders 45 to the outer sides of the support rod 46. Sliding grooves 44 are provided on both sides of the inner wall of the support plate 3, providing ample sliding space for the sliders 45 to rotate smoothly within the grooves 44. The two sliders 45 are slidably connected to the inside of the grooves 44. A scraper 47 is fixedly connected to the bottom of the support rod 46, providing excellent scraping capability. After processing, when the support rod 46 moves towards the discharge mechanism 6, the scraper 47 scrapes the material on the surface of the filter plate 5, removing any remaining solid particles. A cleaning brush 49 is fixedly connected to the bottom of the support rod 46. When the support rod 46 returns to its original position, the cleaning brush 49 cleans the surface of the filter plate 5. The outer side of the cleaning brush 49 is located behind the scraper 47.

[0035] Reference Figure 1 and Figure 3The fixing mechanism 7 includes two support plates 71, designed to provide good support. The two support plates 71 are externally fixedly connected to both sides of the inner wall of the support plate 3. Multiple locking posts 72 are slidably connected to the outside of the two support plates 71, designed to pass through the interior of the support plates 71 and the filter plate 5 in sequence, so that the filter plate 5 can be fixed to the top of the support plate 71. Two fixing blocks 76 are fixedly connected to both sides of the multiple locking posts 72, designed to provide good support. Movable posts 77 are fixedly connected to adjacent sides of the two fixing blocks 76, and the movable posts 77 can provide good rotation ability through the support of the fixing blocks 76. Pressing rods 75 are rotatably connected to the outside of the two movable posts 77, and the pressing rods 75 can rotate through the support of the movable posts 77. Conical plates 78 are fixedly connected to the outside of the two pressing rods 75. Its design is conical. After the conical plate 78 is slid to the top of the filter plate 5, its larger circular bottom surface can be fixed to the top of the filter plate 5. The internal part of the locking post 72 is fixedly connected to the support column 73, which provides good guiding ability. The external part of the support column 73 is fitted with a return spring 74. By pressing the two conical plates 78, the two conical plates 78 can be brought closer together and pass through the top of the filter plate 5. Then, releasing them allows the conical plates 78 to separate at the top of the filter plate 5, thus fixing the filter plate 5. After fixing, by pressing the pressing rods 75 on both sides, the two conical plates 78 can be brought closer together again and slide out from the top of the filter plate 5. The external sides of the return spring 74 are fixedly connected to the adjacent side of the two conical plates 78, and the external part of the locking post 72 is on the adjacent side of the two conical plates 78.

[0036] Working Principle: When using the device, firstly, the material to be screened is placed on top of the filter plate 5. The vibrator 23, driven by an electric power source, generates vibration energy, causing the support plate 3 to vibrate. This vibration is transmitted to the filter plate 5, causing the material to be screened on the filter plate 5. During the vibration process, small particles in the material fall through the sieve holes of the filter plate 5, while larger particles remain on the filter plate 5. At the same time, the motor 42 starts working, and its output end drives the rotating rod 48 to rotate. The rotation of the rotating rod 48 causes the connecting rod 43, which is rotatably connected to it, to rotate as well. The other side of the connecting rod 43 is rotatably connected to the support rod 46, so the rotation of the connecting rod 43 will drive the support rod 46 to move linearly. The outer sides of the support rod 46 are slidably connected to the sliding grooves 44 on both sides of the inner wall of the support plate 3 through the slider 45. This sliding connection allows the support rod 46 to move back and forth smoothly within the sliding grooves 44. When the support rod 46 moves towards the discharge mechanism 6, the scraper 47 fixedly connected to its bottom scrapes the material on the surface of the filter plate 5. This process scrapes away solid particles remaining on the filter plate 5, preventing material accumulation and clogging of the screen holes. Subsequently, when the support rod 46 returns to its original position, the cleaning brush 49 fixed at its bottom cleans the surface of the filter plate 5. Located on the outer rear side of the scraper 47, the cleaning brush 49 further removes residual material and impurities from the surface of the filter plate 5, ensuring unobstructed screen holes and thus achieving the self-cleaning function of the filter plate 5. After screening, small particles fall through the screen holes of the filter plate 5, allowing the inclined plate 61 to convey and collect the screened solid particles, while the discharge plate 62 collects the screened material. Through this design, the vibrating filter screen not only efficiently completes the screening of materials but also maintains the filter plate 5 in good working condition through its self-cleaning function, improving screening efficiency and extending the equipment's service life.

[0037] When installing filter plate 5, first place filter plate 5 on top of the two support plates 71, aligning the locking holes on filter plate 5 with the locking posts 72. Then, the operator presses the pressing rods 75 on both sides, which, through the movable post 77, move the two conical plates 78 closer together. Due to the conical design of the conical plates 78, their larger circular bases gradually taper, allowing the two conical plates 78 to pass through the top of filter plate 5. During this process, the return spring 74 is compressed, generating elastic force. After the conical plates 78 have passed through the top of filter plate 5, the operator releases the pressing rods 75. At this point, the return spring 74 releases its elastic force, pushing the two conical plates 78 apart. The larger circular base of the conical plates 78 is then fixed to the top of filter plate 5, thus firmly securing filter plate 5 to the top of support plates 71, ensuring a secure and reliable fixation of filter plate 5. When filter plate 5 needs to be removed, the operator presses the pressing levers 75 on both sides again. The pressing levers 75, through the movable column 77, drive the two conical plates 78 closer together. The conical plates 78 slide out from the top of filter plate 5, and at the same time, the return spring 74 is compressed. At this time, filter plate 5 is no longer fixed by the conical plates 78 and can be easily removed from the support plate 71. This design allows for convenient and quick installation and removal of filter plate 5, while ensuring the filter plate 5 is firmly fixed during operation, thus improving the efficiency of equipment maintenance and replacement.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
