[0002] Mining machinery is machinery directly used for operations such as mineral mining and enrichment, including mining machinery and mineral processing machinery. Since mining machinery is directly used for mineral excavation, the mechanical parts are subject to greater wear, so wear-resistant liners are required on the equipment. Wear-resistant liners refer to various wear-resistant liners made from wear-resistant steel plates through production processes such as cutting, rolling, punching and welding. The application range of wear-resistant liners is very wide, such as conveyor liners, coal feeder bottom plates, cyclone separator inverted cones and liners, wear-resistant blades, etc. In these applications, wear-resistant liners can improve the wear resistance and durability of the equipment, extend the service life of the equipment, and reduce production and maintenance costs. Wear-resistant liners have excellent wear resistance and impact resistance, and can effectively protect mechanical equipment and structural parts from wear and damage.

[0003] The wear-resistant lining plates currently on the market have wear-resistant balls fixedly installed on the surface of the wear-resistant plates during use. The wear-resistant balls rub against the same place for a long time, resulting in uneven wear of the wear-resistant balls and shortening the service life of the wear-resistant lining plates. In addition, the connecting bolts used for fixed connection are all exposed to the outside and are prone to wear during use, causing the wear-resistant lining plates to fall off during use. Therefore, there is an urgent need for a special wear-resistant lining plate for mining machinery to improve the above problems.

[0027] Example 1

[0028] Reference Figure 1 、 Figure 2 and Figure 3, is a special wear-resistant lining for mining machinery disclosed by the utility model, including a lining plate body 1, a slide groove 2 is opened inside the lining plate body 1, a card slot 3 is opened inside the slide groove 2, a wear-resistant mechanism 4 is arranged inside the card slot 3, and the wear-resistant mechanism 4 includes a mounting box 5, a slider 6 is arranged at the bottom of the mounting box 5, a spring rod 7 is arranged inside the mounting box 5, a ball groove 8 is opened inside the spring rod 7, a wear-resistant ball 9 is arranged inside the ball groove 8, and a baffle 10 is arranged on the top of the wear-resistant ball 9. A limiting plate 11 is provided on one side of the mounting box 5, a mounting hole 12 is opened inside the limiting plate 11, a limiting groove 13 is opened inside the baffle 10, and a fixing mechanism 14 is provided at the bottom of the mounting box 5. In this embodiment, the slide groove 2 plays a role in allowing the slider 6 to pass through, the card slot 3 plays a role in limiting when fixing the mounting box 5, and the spring rod 7 plays a role in buffering when the wear-resistant ball 9 is subjected to a strong impact.

[0029] Reference Figure 2 and Figure 3 The mounting box 5 is slidably assembled with the lining body 1, and the slider 6 is fixed with the card slot 3. In this embodiment, the slider 6 plays the role of connecting to the lining body 1, and the mounting box 5 plays the role of setting the wear-resistant mechanism 4.

[0030] Reference Figure 2 The wear-resistant ball 9 is rotatably connected to the inside of the ball groove 8, and the wear-resistant ball 9 is snap-fitted and assembled with the limiting groove 13. In this embodiment, the wear-resistant ball 9 plays a role in improving the wear resistance, and the limiting groove 13 plays a role in preventing the wear-resistant ball 9 from falling off.

[0031] Reference Figure 2 and Figure 3 The fixing mechanism 14 includes a threaded barrel 15, a fixing bolt 16 is provided inside the threaded barrel 15, an anti-slip hole 17 is provided inside the lining body 1, and a connecting bolt 18 is provided inside the anti-slip hole 17. The fixing bolt 16 passes through the mounting hole 12 in the threaded barrel 15 by screwing, and the limit plate 11 is assembled on the inner side of the lining body 1 through the slide groove 2. In this embodiment, the threaded barrel 15 and the fixing bolt 16 play the role of fixing the mounting box 5, and the anti-slip hole 17 plays the role of limiting the slippage of the connecting bolt 18 during installation.

[0032] The implementation principle of this embodiment is:

[0033] When it is necessary to install the wear-resistant lining, first use a wrench to remove the fixing bolt 16 from the inside of the threaded cylinder 15, lift one end of the installation box 5, so that the slider 6 enters the inside of the slide groove 3 from the slot 3, slide the installation box 5 out of the inside of the slide groove 2, so that the anti-slip hole 17 is exposed to the outside, and install the connecting bolt 18 into the inside of the anti-slip hole 17. Then, the slider 6 enters the inside of the slot 3 from the slide groove 2, the installation hole 12 is concentric with the threaded cylinder 15, and the fixing bolt 16 is rotated and installed in the inside of the threaded cylinder 15 through the installation hole 12, so that the installation box 5 protects the connecting bolt 18. The connecting bolt 18 is used to be installed on the surface of the mining machinery. When wear occurs, the mineral will first contact the wear-resistant ball 9. During the friction of the wear-resistant ball 9, it will rotate under the action of friction, which prolongs the service life of the wear-resistant ball 9. When the mineral rushes to the surface of the wear-resistant lining and contacts the wear-resistant ball 9, the spring rod 7 can play a buffering role to prevent the installation box 5 from being damaged due to the impact force. Therefore, the device has certain practicality.

[0034] Compared with the prior art, the present invention has the following beneficial effects:

[0035] By using the ball groove 8 in conjunction with the limit groove 13, the wear-resistant ball 9 rotates when experiencing friction, so that the wear-resistant ball 9 can be fully worn. By adding the spring rod 7, when the mineral falls off to the liner, it can play a buffering role, avoiding long-term wear of the wear-resistant ball 9 and causing unnecessary waste, thereby extending the service life of the wear-resistant liner. By using the threaded barrel 15 in conjunction with the fixing bolt 16, the installation box 5 can be fixed to the top of the liner body 1, and the connecting bolt 18 is set to the inside of the liner body 1. Then the connecting bolt 18 extends from the inside of the liner body 1 through the anti-slip hole 17, which effectively protects the connecting bolt 18 and avoids the connecting bolt 18 from falling off due to severe wear.

[0036] The embodiments of this specific implementation method are all preferred embodiments of the present utility model, and are not intended to limit the scope of protection of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the scope of protection of the present utility model.
