Description

Technical Field

[0001] This utility model belongs to the field of screen plate technology, specifically relating to a vibrating screen plate for mining with quick-release function. Background Technology

[0002] Mining vibrating screen plates refer to screening components used on mining vibrating screens. They are mainly used for screening and grading materials such as ores and mineral powders. Mining vibrating screen plates are widely used in mining, metallurgy, coal and other industries for screening and grading, improving production efficiency, optimizing product quality, protecting downstream equipment, and saving energy and protecting the environment.

[0003] Chinese patent CN219073570U discloses a novel vibrating screen plate for mining, comprising a screen plate body. Two mounting plates are fixedly installed at the bottom of the screen plate body, and a through-type screw is rotatably installed between the two mounting plates. A slider is threadedly connected to the outer side of the screw, and a guide rod is fixedly installed between the two mounting plates. The slider and guide rod are slidably connected. This utility model has a reasonable structural design. By using a striking plate to strike the screen plate body, it can knock off ore and other debris stuck in the screen holes on the surface of the screen plate body. This avoids the problem of the screen holes being blocked by ore and other debris after long-term use, thus preventing the need for manual replacement of the screen plate body. The striking plate moves while striking, significantly increasing the striking range and greatly improving cleaning efficiency.

[0004] Although the aforementioned mining vibrating screen plate can greatly improve cleaning efficiency by slapping the screen with the slapping plate, the screen plate has a relatively fixed structure, which makes disassembly and assembly inconvenient and affects the maintenance and replacement efficiency of the equipment. Therefore, we propose a mining vibrating screen plate with quick disassembly function. Utility Model Content

[0007] Positioning blocks are provided on both sides above the screen plate body. A telescopic spring is fixed on the upper part of the positioning block. A rotating block is fixed above the telescopic spring. A limit slide is slidably installed on the upper part of the rotating block.

[0008] As a preferred embodiment of the vibrating screen plate with quick-release function for mining, the screen plate body is engaged with the mounting block through the hook and the mounting groove, and the size of the hook and the mounting groove are matched.

[0009] As a preferred embodiment of the vibrating screen plate with quick-release function for mining applications according to this utility model, the rotating block forms an elastic structure with the positioning block through the telescopic spring.

[0010] In a preferred embodiment of this utility model, a vibrating screen plate for mining with a quick-release function is provided, wherein the vibrating motor is connected to the screen plate body via the vibrating block and the mounting block.

[0011] As a preferred embodiment of the vibrating screen plate with quick-release function for mining applications according to this utility model, a linkage block is fixed on one side below the limiting slide plate, and one end of the linkage block is connected to a telescopic push rod.

[0012] As a preferred embodiment of the vibrating screen plate with quick-release function for mining, a positioning shaft is provided on one side of the rotating block, and the rotating block is movably connected to the screen box through the positioning shaft.

[0013] Compared with the prior art, the beneficial effects of this utility model are: in this application, the screen plate body is engaged with the mounting block through hooks and mounting grooves, which facilitates the quick installation and disassembly of the screen plate body. The horizontal sliding of the limiting slide plate can realize the fixing and unlocking of the screen plate body, preventing the screen plate from having a relatively fixed structure, which has problems with inconvenient disassembly and assembly, and affecting the maintenance and replacement efficiency of the equipment.

[0021] 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.

[0022] Example 1

[0023] like Figures 1-5 As shown;

[0024] A mining vibrating screen plate with quick-release function includes a screen box 1. Vibrating motors 2 are bolted to both sides of the screen box 1. Vibrating blocks 3 are fixed to the drive end of the vibrating motors 2. Mounting blocks 4 are fixed to the inner side of the vibrating blocks 3. Screen plate body 6 is mounted on the inner side of the mounting blocks 4. Hooks 7 are fixed to both sides of the screen plate body 6. Mounting grooves 5 are provided at the connection between the hooks 7 and the mounting blocks 4. Positioning blocks 10 are provided on both sides above the screen plate body 6. A telescopic spring 9 is fixed to the upper part of the positioning block 10. A rotating block 8 is fixed above the telescopic spring 9. A limit slide plate 12 is slidably mounted above the rotating block 8.

[0025] In this implementation scheme: the screen plate body 6 is engaged with the mounting block 4 through the hook 7 and the mounting groove 5, thereby facilitating the quick installation and disassembly of the screen plate body 6. The horizontal sliding of the limiting slide plate 12 can realize the fixing and unlocking of the screen plate body 6.

[0026] Furthermore:

[0027] In an optional embodiment, the screen plate body 6 is engaged with the mounting block 4 by means of hooks 7 and mounting grooves 5, wherein the dimensions of the hooks 7 and the mounting grooves 5 are matched.

[0028] In this implementation scheme: the screen plate body 6 can be engaged with the mounting block 4 through the hook 7 and the mounting groove 5, thereby enabling the screen plate body 6 to be quickly installed and disassembled.

[0029] Furthermore:

[0030] In an optional embodiment, the rotating block 8 forms an elastic structure with the positioning block 10 via the telescopic spring 9.

[0031] In this implementation plan, the elastic structure formed by the telescopic spring 9 and the rotating block 8 automatically compensates for the displacement deviation caused by vibration through dynamic compression and reset functions, ensuring the continuous pressing force of the limit slide plate 12 on the screen plate body 6, preventing the hook 7 from accidentally coming off, and enhancing the reliability of the equipment.

[0032] Furthermore:

[0033] In an optional embodiment, the vibration motor 2 is connected to the screen plate body 6 via the vibration block 3 and the mounting block 4.

[0034] In this implementation scheme: the vibration motor 2 directly drives the screen plate body 6 through the vibration block 3 and the mounting block 4. The rigid connection design between the mounting block 4 and the screen plate body 6 improves vibration synchronization, avoids local stress concentration on the screen plate, and extends service life.

[0035] Furthermore:

[0036] In an optional embodiment, a linkage block 13 is fixed to one side below the limiting slide plate 12, and one end of the linkage block 13 is connected to a telescopic push rod 14.

[0037] In this implementation scheme: the telescopic push rod 14 can drive the limiting slide plate 12 to slide laterally through the linkage block 13, which facilitates locking and unlocking of the rotating block 8.

[0038] Furthermore:

[0039] In an optional embodiment, a positioning shaft 11 is provided on one side of the rotating block 8, and the rotating block 8 is movably connected to the screen box 1 through the positioning shaft 11.

[0040] In this implementation scheme: the positioning shaft 11 provides a stable rotation fulcrum for the rotating block 8, which facilitates the rotation of the rotating block 8 and the installation and removal of the screen plate body 6.

[0041] Working principle: First, install the screen plate body 6, and engage the hooks 7 on both sides of the screen plate body 6 into the mounting grooves 5 inside the mounting block 4. Initial positioning is achieved through the engagement of the hooks 7 with the grooves. Then, rotate the rotating block 8 to a horizontal position and activate the telescopic push rod 14. The telescopic push rod 14 drives the linkage block 13 to slide the limiting slide plate 12 laterally inward, thus limiting the rotation of the rotating block 8. The rotating block 8 has a square lower end and an arc upper end, and can only rotate upwards, not downwards. Secondly, under the elastic force of the telescopic spring 9, the rotating block 8 interacts with the positioning block 10, thereby limiting the screen plate body 6 and preventing the screen plate from coming off during vibration. Then, start the vibration motor 2 and feed the material into the screen box 1. The drive end of the vibration motor 2 drives the vibrating block 3 to generate high-frequency vibration. Kinetic energy is transmitted through the vibrating block 3 to the mounting block 4, which is fixedly connected to it. The mounting block 4 further transmits the vibration to the screen plate body 6, causing it to reciprocate within the screen box 1, thereby achieving the screening function for materials such as ores. The dynamic compensation mechanism of the vibrating motor 2, vibrating block 3, mounting block 4, screen plate body 6, and elastic structure takes into account both screening efficiency and equipment operation stability. After use, the screen plate body 6 should be maintained regularly. When the screen plate body 6 needs to be disassembled, the telescopic push rod 14 is activated. The telescopic push rod 14 drives the linkage block 13 to slide the limit slide plate 12 laterally outward, thereby unlocking the limit on the rotating block 8. Then, the rotating block 8 is rotated upward to the maximum angle through the positioning shaft 11, so that the positioning block 10 is moved away from the screen plate body 6, making it easy to remove the screen plate body 6.

[0042] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
