Description

Technical Field

[0001] This utility model relates to the field of wear-resistant materials and components, and in particular to a detachable and combinable wear-resistant ball. Background Technology

[0002] Traditional wear-resistant balls are mostly solid structures, and often need to be replaced as a whole after the surface wears down during use, resulting in high maintenance costs and serious material waste. Although modular wear-resistant balls with replaceable wear-resistant ball surfaces have emerged, early connection methods have defects such as easy separation. With the development of mechanical connection technology, more robust detachable structures such as threads and snaps have been applied, so that when wear-resistant ball parts are damaged, only the damaged parts need to be replaced, reducing costs and facilitating maintenance. Thus, detachable modular wear-resistant balls have emerged.

[0003] When the detachable and modular wear-resistant balls are in operation, they fall to a high position as the ball mill cylinder rotates. They impact the material with gravity and kinetic energy, and are crushed by squeezing and friction. The modular structure optimizes the function. The outer grinding shell bears the main wear and can be replaced separately when damaged. The inner weight-bearing skeleton and other components are not affected. The threaded and snap-fit ​​connection structure ensures that each component is subjected to force in a coordinated manner, avoiding stress concentration. This maintains grinding efficiency and improves resource utilization and maintenance efficiency through flexible disassembly.

[0004] Modern modular wear-resistant balls significantly reduce maintenance costs and improve resource utilization, injecting new momentum into grinding operations in industries such as mining and cement. However, in practical applications, when some components wear out and need to be replaced, improper selection of the connection structure or insufficient assembly precision can easily lead to the risk of insecure fixing. During operation, there is severe impact and vibration inside the high-speed rotating cylinder, and loose components may detach from the main body. This can cause a sharp drop in grinding efficiency or even blockage of cylinder gaps, leading to equipment downtime or mechanical failure, which in turn exacerbates the risk of production interruption. This highlights the urgency of optimizing connection technology and assembly processes. Therefore, modular wear-resistant balls are proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a detachable and combinable wear-resistant ball, which aims to improve the problem in the prior art where loose components detach from the main body due to improper selection of the connection structure or insufficient assembly precision.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A detachable and combinable wear-resistant ball includes a base, a plurality of connecting posts are fixedly connected to the outer wall of the base, a fixing plate is fixedly connected to the end of each of the plurality of connecting posts away from the base, the fixing posts are internally threaded to the fixing plate, a plurality of outer shells are installed on the outside of the base, and mounting components are provided on the outer wall of the fixing posts;

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

[0009] The mounting assembly includes screw threads, the outer wall of the fixing column is provided with screw threads, and a positioning plate is placed on the side of the fixing plate away from the connecting column;

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

[0011] The positioning disk has screw threads inside, and the outer wall of the fixing column and the inner wall of the positioning disk are connected by the screw threads.

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

[0013] A protrusion is provided on the side of the fixing post away from the fixing plate, and one side of the protrusion is in contact with one side of the positioning plate;

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

[0015] The fixing post has a groove on the side away from the fixing plate, and the groove is cross-shaped.

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

[0017] The outer wall of the positioning disk slides on the inner wall of the outer shell, and the cross-section of the positioning disk is T-shaped;

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

[0019] One side of the fixed plate is in contact with one side of the outer shell, and multiple pits are formed on the side of the outer shell away from the base;

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

[0021] The protrusion has a hexagonal cross-section, and one side of the positioning disk is in contact with one side of the fixing disk.

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

[0023] 1. In this utility model, by precisely embedding the tip of a screwdriver into the inner wall of the groove at the top of the fixing post, and smoothly rotating it counterclockwise, the screwdriver overcomes the resistance of the thread by lever principle, and the fixing post is unscrewed from the inside of the fixing plate for disassembly. Subsequently, the damaged outer shell can be easily removed from one side of the fixing plate because it is no longer constrained by the fixing post. After replacing it with a new outer shell, the positioning plate is aligned with the preset slot inside the outer shell and pressed vertically to ensure accurate positioning. Finally, the screwdriver is used again to press against the groove and rotate clockwise. Through the thread engagement, the outer shell and the fixing plate are gradually tightened, so that the outer shell and the fixing plate are tightly locked. The test shows that it is stable and does not wobble, thus completing the efficient repair.

[0024] 2. In this utility model, multiple irregularly arranged pits are provided on one side of the outer shell. Their distribution follows the principles of fluid mechanics and tribology. During the grinding operation, these pits can effectively disrupt the contact pattern between the material and the surface of the outer shell, forming a buffer layer of air or lubricating medium, significantly reducing the coefficient of sliding friction. This not only reduces energy consumption but also avoids material peeling and wear caused by excessive local friction, thus extending the average service life of the outer shell and greatly improving the overall economy and reliability of the wear-resistant ball.

[0031] 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.

[0032] Reference Figure 1 and Figure 2This utility model provides an embodiment of a detachable and combinable wear-resistant ball, including a base 1, which serves as a support. Multiple connecting posts 2 are fixedly connected to the outer wall of the base 1, and the connecting posts 2 are evenly distributed on the outer wall of the base 1. A fixing plate 3 is fixedly connected to the end of each connecting post 2 away from the base 1. A fixing post 4 is threadedly connected to the inside of the fixing plate 3, allowing the fixing post 4 and the fixing plate 3 to be detached and fixed. Multiple outer shells 7 are installed on the outside of the base 1, and the outer shells 7 play an important grinding role. An installation component, including screw threads 5, is provided on the outer wall of the fixing post 4. A positioning plate 9 is placed on the side of the fixing plate 3 away from the connecting posts 2, making the entire ball more stable. Screw threads 5 are provided inside the positioning plate 9. The outer wall of the fixing post 4 and the inner wall of the positioning plate 9 are threadedly connected by screw threads 5, so that the fixing post 4 is located inside the positioning plate 9.

[0033] Reference Figures 2 to 4 The fixing post 4 has a protrusion on the side away from the fixing plate 3. One side of the protrusion contacts one side of the positioning plate 9, so that the fixing post 4 can firmly fix the positioning plate 9. The fixing post 4 has a groove 6 on the side away from the fixing plate 3. The groove 6 is cross-shaped, so that the screwdriver can just abut against the groove 6. The outer wall of the positioning plate 9 slides on the inner wall of the outer shell 7, so that the positioning plate 9 can slide out from the inside of the outer shell 7. The cross-section of the positioning plate 9 is T-shaped, making the whole ball more stable. One side of the fixing plate 3 contacts one side of the outer shell 7. The outer shell 7 has multiple pits 8 on the side away from the base 1, which greatly reduces the friction force on the outer shell 7 during grinding, thereby extending the service life of the outer shell 7. The protrusion has a hexagonal cross-section. One side of the positioning plate 9 contacts one side of the fixing plate 3, so that the positioning plate 9 can firmly fix the outer shell 7.

[0034] Working principle: When the detachable and combinable wear-resistant ball has been in operation for a certain period of time, and part of the outer shell 7 is worn and needs to be replaced, use a screwdriver to press against the inner wall of the groove 6 and then rotate it to remove the fixing post 4 from the inside of the fixing plate 3. Then remove the worn outer shell 7 from one side of the fixing plate 3, place the new outer shell 7, press the positioning plate 9 into the inside of the outer shell 7, and then use a screwdriver to press against the groove 6 and rotate it to make the outer shell 7 firmly fixed.

[0035] 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.
