Technical Field
[0001] This utility model belongs to the field of screening technology, specifically relating to a screening device with a self-cleaning function. Background Technology
[0002] The process of separating loose materials into different particle sizes by passing them through one or more screens is called screening. A screening machine is a vibrating screening machine that uses the relative motion between the loose material and the screen surface to allow some particles to pass through the screen holes and separate them into different grades according to particle size.
[0003] Current equipment cannot effectively self-clean the filter, and prolonged use may cause the filter to become clogged, thus affecting the product's usability. Therefore, improvements are needed. Utility Model Content
[0004] The purpose of this invention is to provide a screening device with a self-cleaning function to solve the problems existing in the background art.
[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:
[0006] A screening device with a self-cleaning function includes a screening frame, an inclined screening screen installed inside the screening frame, a feeding frame installed at the upper end of the screening frame, four mounting columns fixedly installed at the upper end of the screening frame, a threaded rod rotatably installed between two of the mounting columns, a drive motor connected to the threaded rod installed on the mounting column, and a concave-convex plate fixedly installed on the other two mounting columns. The threaded rod is threadedly connected to a mounting plate slidably connected to the concave-convex plate, and a U-shaped plate is slidably installed left and right inside the mounting plate. Several brushes are installed at the lower end of the U-shaped plate.
[0007] The U-shaped plate is fixedly installed with an abutment plate that matches the concave-convex plate, and the U-shaped plate is elastically connected to the mounting plate.
[0008] The mounting plate has an internal mounting groove that slides up and down with the U-shaped plate. A sliding block is fixedly installed at the upper end of the mounting plate. A spring plate is slidably connected to the sliding block from left to right. A first spring is installed between the spring plate and the mounting plate. The spring plate is installed together with the U-shaped plate.
[0009] An adjusting threaded rod that is threadedly connected to the spring plate is rotatably mounted on the upper end of the U-shaped plate, and a handle is mounted on the upper end of the adjusting threaded rod.
[0010] The threaded rod is fixedly mounted with a circular plate extending into the mounting column. An eccentric column is eccentrically mounted on the circular plate. A rectangular groove matching the circular plate is opened inside the mounting column. A limiting frame that slides and connects with the rectangular groove is sleeved on the outside of the eccentric column. An L-shaped rod that abuts against the inclined screening screen is fixedly mounted at the lower end of the limiting frame. Several second springs are installed at the lower end of the inclined screening screen. The inclined screening screen and the screening frame are slidably connected up and down.

Detailed Implementation
[0025] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.
[0026] Example 1: As Figure 1-7 As shown, a screening device with a self-cleaning function of the sieve according to the present invention includes a screening frame 1, an inclined screening screen 11 installed inside the screening frame 1, a feeding frame 12 installed at the upper end of the screening frame 1, four mounting columns 13 fixedly installed at the upper end of the screening frame 1, a threaded rod 14 rotatably installed between two mounting columns 13, a drive motor 15 connected to the threaded rod 14 and the other two mounting columns 13 are fixedly installed with concave and convex plates 16, the threaded rod 14 is threadedly connected to a mounting plate 17 that is slidably connected to the concave and convex plates 16, a U-shaped plate 18 is slidably installed inside the mounting plate 17, and several brushes 19 are installed at the lower end of the U-shaped plate 18;
[0027] The U-shaped plate 18 is fixedly installed with an abutment plate 20 that matches the convex and concave plate 16, and the U-shaped plate 18 is elastically connected to the mounting plate 17.
[0028] In use, the items to be screened are placed into the feed frame 12, allowing them to slide downwards from the top of the inclined screen 11. During this sliding process, items that fit the screen holes will fall through the holes. By placing the existing collection device at the bottom of the screening frame 1, items passing through the inclined screen 11 can be collected. At this time, the mounting plate 17 is located at the bottom of the inclined screen 11. When cleaning is required, the drive motor 15 drives the threaded rod 14 to rotate. Since the mounting plate 17 is slidably connected to the upper and lower sides of the concave and convex plates 16, the rotation of the threaded rod 14 will drive the mounting plate 17 to rotate. Plate 17 slides along the direction of threaded rod 14, thereby driving U-shaped plate 18 and several brushes 19 to slide. During the sliding process of U-shaped plate 18, under the action of elastic connection, the abutting plate 20 will always abut against the concave and convex plate 16 on the side facing threaded rod 14. Then, during the sliding process of mounting plate 17, the abutting plate 20 will overcome the rebound force of elastic connection and move towards threaded rod 14. Under the action of elastic connection, when it encounters the concave part of concave and convex plate 16, it will move towards concave and convex plate 16. In this way, U-shaped plate 18 will sweep left and right during the back and forth movement of inclined screening screen 11, improving cleaning efficiency.
[0029] This invention can sweep the inclined screen back and forth along the direction of the brush, and sweep the inclined screen left and right with the cooperation of the concave and convex plates and the elastic connection, thereby improving the cleaning efficiency.
[0030] The mounting plate 17 has an internal mounting groove that slides vertically and vertically with the U-shaped plate 18. A sliding block 21 is fixedly installed on the upper end of the mounting plate 17. A spring plate 22 is slidably connected to the sliding block 21. A first spring 23 is installed between the spring plate 22 and the mounting plate 17. The spring plate 22 is installed together with the U-shaped plate 18.
[0031] An adjusting threaded rod 24, which is threadedly connected to the spring plate 22, is rotatably mounted on the upper end of the U-shaped plate 18. A handle 25 is mounted on the upper end of the adjusting threaded rod 24.
[0032] The sliding block 21 and the spring plate 22 are slidably connected to each other, which can drive the adjusting threaded rod 24 and the U-shaped plate 18 rotatably mounted thereto to slide left and right. The spring plate 22 is equipped with the first spring 23, which will cause the spring plate 22 to drive the threaded rod 24 and the U-shaped plate 18 rotatably mounted thereto to have elastic potential energy, and then cooperate with the concave and convex plate 16 to slide left and right.
[0033] The installation of handle 25 allows for easy rotation of the adjusting threaded rod 24. Simultaneously, when cleaning is required, rotating the adjusting threaded rod 24 causes the U-shaped plate 18 to slide downwards, exposing the mounting plate 17. This allows the brush 19 to contact the inclined screening screen 11 for cleaning. When not in use, the brush 19 can be stored inside the mounting plate 17 without affecting the screening of items.
[0034] Example 2: Based on Example 1, a further improvement is made. A circular plate 26 extending into the mounting column 13 is fixedly installed on the threaded rod 14. An eccentric column 27 is eccentrically fixedly installed on the circular plate 26. A rectangular groove 28 matching the circular plate 26 is opened inside the mounting column 13. A limiting frame 29 that is slidably connected to the rectangular groove 28 is sleeved on the outside of the eccentric column 27. An L-shaped rod 30 that abuts against the inclined screening screen 11 is fixedly installed at the lower end of the limiting frame 29. Several second springs 31 are installed at the lower end of the inclined screening screen 11. The inclined screening screen 11 and the screening frame 1 are slidably connected up and down.
[0035] When cleaning is required, starting the drive motor 15 will rotate the circular plate 26, which in turn will cause the eccentric column 27 to rotate eccentrically. Since the fiber frame 29 and the rectangular groove 28 are slidably connected, and the limiting frame 29 is located outside the eccentric column 27, the rotation of the eccentric column 27 will cause the limiting frame 29 to slide up and down, which in turn will cause the L-shaped rod 30 to slide up and down, causing the inclined screening screen 11 to move upward and pull the second spring 31. After the tension is released, the second spring 31 will cause the inclined screening screen 11 to return to its initial state. In this way, the inclined screening screen 11 can be made to shake up and down by the drive motor 15 to improve the screening efficiency.
[0036] The inclined screening screen 11 consists of a fine screen 32, a medium screen 33, and a coarse screen 34. This allows small particles to pass through the inclined screening screen 11 first, thereby separating items of different sizes.
[0037] The U-shaped plate 18 has a water channel 35 inside, and a water outlet 36 connected to the water channel 35 is opened at the lower end of the U-shaped plate 18. When cleaning water is added to the water channel 35, the cleaning water will be discharged from the water outlet 36. The water outlet 36 is located between the brushes 19, which, together with the brushing motion of the brushes 19, improves the cleaning efficiency and also cleans the brushes 19.
[0038] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
