Description

Technical Field

[0001] This utility model relates to the field of vibrating screen technology, and in particular to a vibrating screen that is easy to replace the screen mesh. Background Technology

[0002] In vibrating screens, the grading efficiency and operational reliability of the vibrating screen have a decisive impact on the overall production capacity and product quality of the process. To achieve precise and efficient material screening, it is usually necessary to use structurally optimized vibrating screen equipment. This equipment typically includes core functional modules such as excitation drive, screen frame structure, and shock-absorbing support. Especially when processing high-moisture or fine powder materials, the ease of screen cleaning and sealing performance directly affect the operating efficiency and working environment, as screen clogging and wear intensify. Therefore, developing a modular, efficient, and easy-to-maintain vibrating screen device has become an important direction for process optimization.

[0003] In existing technologies, vibrating screens used for material screening generally include a vibrator system, a screen fixing mechanism, and a sealing and dustproof structure. Structurally, the screen frame is equipped with a clamping device for installing the screen, using bolts, wedges, or other methods to secure it. It is also equipped with rubber sealing strips or dust covers to prevent dust from escaping during the screening process, thus improving the working environment. In actual use, the screen is usually tightly fitted to the screen frame clamping structure, requiring the removal of numerous bolts for replacement or cleaning. Furthermore, the sealing components and screen cleaning device are mostly fixed designs, making maintenance inconvenient and time-consuming.

[0004] However, existing vibrating screens still have certain problems in practical applications. On the one hand, it is not convenient and quick to clean the waste on the filter screen. Traditional structures cannot be cleaned quickly and easily, which affects the filtration work. On the other hand, replacing the filter screen is cumbersome. The above problems reduce the convenience of the vibrating screen and urgently need to be optimized in structural design. Therefore, a vibrating screen that is easy to replace the screen is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a vibrating screen that facilitates screen replacement, aiming to improve the problem of the inability to clean the filter screen in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a vibrating screen that facilitates screen replacement, comprising a baffle, a cleaning component inside the baffle, a quick-change component inside the baffle, a vibration component at the bottom of the baffle, and a filter screen on the inner wall of the baffle;

[0007] The cleaning assembly includes a brush plate, the outer wall of which slides inside a baffle. The baffle has two inner grooves: a second inner groove and a seventh inner groove. A sliding block is slidably connected inside the baffle. A limit block is fixedly connected to the outer wall of the sliding block, which is slidably connected inside the seventh inner groove. A connecting post is fixedly connected to the bottom of the sliding block. The outer wall of the connecting post is slidably connected inside the second inner groove. A spring is sleeved on the outer wall of the connecting post. One end of the spring is fixedly connected to one end of the sliding block, and the other end is fixedly connected inside the baffle. The outer wall of the brush plate slides inside the first inner groove.

[0008] As a further description of the above technical solution:

[0009] The vibration assembly includes a fixed frame, the outer wall of which is fixedly connected to the outer wall of the baffle, a second fixed column is fixedly connected to the bottom of the fixed frame, and a first fixed column is fixedly connected to the bottom of the second fixed column.

[0010] As a further description of the above technical solution:

[0011] A spring three is fitted on the outer wall of the second fixed column. One end of the spring three is fixedly connected to the bottom of the fixed frame, and the other end of the spring three is fixedly connected to the top of the first fixed column.

[0012] As a further description of the above technical solution:

[0013] The quick-change assembly includes a drive column, the outer wall of which is slidably connected to the inside of the baffle, a push post fixedly connected to one end of the drive column, and a fixing block fixedly connected to the other end of the drive column.

[0014] As a further description of the above technical solution:

[0015] A second spring is sleeved on the outer wall of the drive column. One end of the second spring is fixedly connected to one end of the push column, and the other end of the second spring is fixedly connected to the outer wall of the baffle.

[0016] As a further description of the above technical solution:

[0017] A limiting strip is fixedly connected to the outer wall of the baffle, the bottom of the filter screen slides on the top of the limiting strip, and the outer wall of the filter screen slides on the outer wall of the baffle.

[0018] As a further description of the above technical solution:

[0019] The filter screen has an inner groove five, an inner groove eight, an inner groove six, and the baffle has an inner groove three.

[0020] As a further description of the above technical solution:

[0021] The fixing block slides inside inner groove five, the fixing block slides inside inner groove eight, the fixing block slides inside inner groove six, the driving column slides inside inner groove eight, and the outer wall of the fixing block slides inside inner groove three.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the brush plate is first pulled upward. The sliding block has an inclined structure. When the brush plate is pulled upward, it will compress the sliding block inward. The sliding block compresses the spring, and the brush plate slides to the top. Then it is pulled to the right to clean the filter screen. After cleaning, the brush plate is reset. The sliding block limits the brush plate under the action of the spring, thus achieving the effect of cleaning the filter screen. This solves the problem that the vibrating screen cannot clean the filter screen and improves the convenience of the vibrating screen.

[0024] 2. In this utility model, pressing down the push button compresses the spring, and then rotating the push button causes the column to rotate, which in turn moves the fixing column away from the inner groove six. Then, releasing the push button allows the fixing block to slide into the inner groove three under the spring's rebound. After removing the filter screen, the replacement filter screen is slid in. Pressing down the push button again and rotating it, and releasing the push button allows the fixing block to slide into the inner groove six under the spring's rebound, thus achieving the effect of convenient filter screen replacement. This solves the problem of the vibrating screen's inability to conveniently replace the filter screen and improves the convenience of the vibrating screen. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 Figures 1-2 The present invention provides an embodiment of a vibrating screen with easy screen replacement, including a baffle 1, which forms the main structure of the vibrating screen, provides material screening space, and withstands vibration impact. A cleaning component is provided inside the baffle 1 to clean the filter screen 13, making the screening more accurate. A quick-change component is provided inside the baffle 1 to quickly and conveniently replace the filter screen 13, improving work efficiency. A vibration component is provided at the bottom of the baffle 1 to accelerate the screening process and greatly improve screening efficiency. A filter screen 13 is provided on the inner wall of the baffle 1, and the replaceable mesh design can adapt to the separation needs of materials with different particle sizes.

[0034] The cleaning assembly includes a brush plate 3, used to scrape away residual material clogging the mesh of the filter screen 13, maintaining the screen's permeability and improving screening efficiency. The outer wall of the brush plate 3 slides inside the baffle 1. The baffle 1 has an inner groove 6 to limit the vertical and horizontal movement of the connecting column 8, preventing overload damage to the mechanism or deviation from its position. The baffle 1 also has an inner groove 18 to provide a vertical sliding track for the sliding block 4, ensuring linear motion accuracy. A sliding block 4 is slidably connected inside the baffle 1 to limit the brush plate 3. The sliding block 4 has an inherent inclined structure, which can compress the spring 7 inward when the brush plate 3 slides over it, allowing the brush plate 3 to slide over. A limit block 5 is fixedly connected to the outer wall of the sliding block 4 to limit its displacement range, preventing collision damage and detachment. The outer wall of the sliding block 4 is slidably connected inside the inner groove 18 to provide a vertical sliding track for the sliding block 4, ensuring linear motion accuracy. A connecting column 8 is fixedly connected to the bottom of the sliding block 4 to provide stable support for the spring 7. To prevent deviation during compression and thus affect compression, the outer wall of the connecting column 8 is slidably connected to the inside of the inner groove 6. The outer wall of the connecting column 8 is fitted with a spring 7 to provide elastic restoring force, so that the sliding block 4 automatically resets and realizes continuous scraping cycle. One end of the spring 7 is fixedly connected to one end of the sliding block 4, and the other end of the spring 7 is fixedly connected to the inside of the baffle 1. The outer wall of the brush plate 3 slides inside the inner groove 2. The vibration assembly includes a fixed frame 20 for installing the shock absorption mechanism and transmitting the working load of the vibrating screen. The outer wall of the fixed frame 20 is fixedly connected to the outer wall of the baffle 1. The bottom of the fixed frame 20 is fixedly connected to a fixed column 23 for connecting the shock absorption spring, which serves as the core support of the vibration buffer system. The bottom of the fixed column 23 is fixedly connected to a fixed column 21 to provide the equipment grounding support point and disperse the vibration energy to the ground. The outer wall of the fixed column 23 is fitted with a spring 32. One end of the spring 32 is fixedly connected to the bottom of the fixed frame 20, and the other end of the spring 32 is fixedly connected to the top of the fixed column 11.

[0035] Reference Figures 3-5The quick-change assembly includes a drive column 10 for transmitting operating force and driving the fixed block 11 to move within the multi-channel, enabling quick unlocking and locking of the filter screen 13. The outer wall of the drive column 10 is slidably connected to the inside of the baffle 1. One end of the drive column 10 is fixedly connected to a push post 9, which provides a human-machine interface. The quick-change assembly is controlled by pressing, reducing the operational intensity of changing the screen. One end of the drive column 10 is fixedly connected to the fixed block 11, which is used to fix the position of the filter screen 13 through mechanical interlocking, withstand vibration and impact, and prevent the screen from shifting. A second spring 14 is sleeved on the outer wall of the drive column 10. After the push post 9 is released, it automatically pushes the fixed block 11 back to its locked position, ensuring a stable working state. One end of the second spring 14 is fixedly connected to one end of the push post 9, and the other end of the second spring 14 is fixedly connected to the outer wall of the baffle 1. A limit strip 19 is fixedly connected to the outer wall of the baffle 1, which provides the installation benchmark and horizontal positioning of the filter screen 13, ensuring more stable screen operation. When changing filters, the bottom of the filter 13 slides on the top of the limiting strip 19, and the outer wall of the filter 13 slides on the outer wall of the baffle 1. The filter 13 has an inner groove 5 15, which forms a main locking track with the fixing block 11. The filter 13 has an inner groove 8 16, which provides a linkage channel to ensure that the moving column 10 and the fixing block 11 move synchronously. The filter 13 has an inner groove 6 17, which forms a locking track for the fixing block 11 to enhance vibration resistance and fix the filter 13 to the outer wall of the baffle 1. The baffle 1 has an inner groove 3 12, which allows the fixing block 11 to retract when the filter 13 is removed, so that the filter 13 can be removed without damage. The fixing block 11 slides inside the inner groove 5 15, the inner groove 8 16, and the inner groove 6 17, causing the moving column 10 to slide inside the inner groove 8 16. The outer wall of the fixing block 11 slides inside the inner groove 3 12.

[0036] Working principle: First, pull the brush plate 3 upward. The sliding block 4 has an inclined structure. When the brush plate 3 is pulled upward, it will compress the sliding block 4 inward. The sliding block 4 compresses the spring 7, and the brush plate 3 slides to the upper end. Then, it is pulled to the right to clean the filter screen 13. After cleaning, the brush plate 3 is pulled to the left and then pulled downward to compress the sliding block 4. The sliding block 4 compresses the spring 7. When the brush plate 3 returns to its original position, the sliding block 4 limits the brush plate 3 under the action of the spring rebound, thus achieving the effect of cleaning the filter screen 13.

[0037] Press the button 9, which compresses the spring 14. The button 9 then drives the drive column 10 inward, which in turn compresses the fixing block 11, disengaging it from the inner groove 17. Then rotate the button 9 and release it. Under the rebound of the spring 14, the fixing block 11 and the drive column 10 slide out of the inner groove 16, and the fixing block 11 slides into the inner groove 12. At this point, the filter screen 13 and the baffle 1 are no longer fixed. Remove the filter screen 13 and slide the replacement filter screen 13 into the designated position. Press the button 9 again and rotate it. Under the rebound of the spring 14, the fixing block 11 is fixed in the inner groove 17, thus achieving the effect of replacing the filter screen 13.

[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.
