Description

Technical Field

[0001] This utility model relates to the field of cone crusher technology, and in particular to a cone crusher liner. Background Technology

[0002] A cone crusher is a typical piece of equipment for fine crushing of materials, widely used in mining, metallurgy, construction, road building, and chemical industries. It features high crushing force, high efficiency, high throughput, low operating costs, convenient adjustment, and economical use. The cone crusher forms a crushing chamber between the moving cone liner and the fixed cone liner. The moving cone liner's high-frequency oscillation applies compression or high-frequency vibration impact to the material, achieving crushing. In a cone crusher, the fixed and moving cone liners are the most critical components. Their working conditions mainly involve harsh conditions such as ore wear and impact. Their service life is affected by factors such as the liner's structure, material, wear resistance, and impact toughness.

[0003] Traditional cone crushers have some drawbacks. During operation, material enters the machine through the feed inlet and directly contacts the moving liner, causing a large amount of material to accumulate and block the top of the crushing chamber. This results in the moving liner being subjected to severe wear and impact from the material during operation, thus shortening its service life. Utility Model Content

[0004] The main purpose of this utility model is to provide a cone crusher liner that can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

Detailed Implementation

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figure 1-4 As shown, a cone crusher liner includes a crushing chamber 1, a fixed liner 2, and a feed inlet 4. A crushing auxiliary mechanism 6 is provided inside the crushing chamber 1. The crushing auxiliary mechanism 6 includes a fixed frame 61 fixedly connected to the inner wall of the crushing chamber 1. A support rod 62 is fixedly connected to the inner wall of the fixed frame 61. A connecting seat 63 is fixedly connected to the rear end of the support rod 62. A drive shaft 64 is movably installed inside the connecting seat 63. A movable liner 65 is fixedly connected to the upper end of the drive shaft 64. A crushing corresponding groove 66 is opened on the outer side of the movable liner 65. A connecting rod 67 is fixedly connected to the upper end of the movable liner 65. An internal threaded ring 68 is threadedly connected to the outer side of the connecting rod 67. A distribution plate 69 is fixedly connected to the outer side of the internal threaded ring 68. The movable liner 65 is conical in shape.

[0021] In this embodiment, a retaining ring 610 is fixedly connected to the outer side of the connecting rod 67 near the lower side of the internal threaded ring 68. The center lines of the crushing chamber 1, the fixing frame 61, the connecting seat 63, the transmission shaft 64, and the moving liner 65 are located on the same straight line. There are multiple sets of crushing corresponding grooves 66. The material distribution plate 69 is conical in shape. The lower end of the internal threaded ring 68 is in contact with the upper end of the retaining ring 610. The center lines of the moving liner 65, the connecting rod 67, the internal threaded ring 68, the material distribution plate 69, and the retaining ring 610 are located on the same straight line.

[0022] Specifically, the drive unit rotates the transmission shaft 64 within the connecting seat 63, and the transmission shaft 64 also rotates the moving liner 65 within the fixed liner 2. This causes the distribution plate 69 to rotate along with the moving liner 65. At this point, the worker pours material into the feed inlet 4, causing the material to contact the distribution plate 69. The material then slides down the distribution plate 69 in all directions, falling into the gap between the fixed liner 2 and the moving liner 65. This causes the moving liner 65 to... The outer crushing groove 66, in conjunction with the crushing groove 5 on the inner wall of the fixed liner plate 2, crushes the material. By pouring the material into the feed inlet 4 and making it contact the distribution plate 69, the material slides down the surface of the distribution plate 69 to the surrounding areas. This facilitates the material falling into the gap between the fixed liner plate 2 and the moving liner plate 65, thereby preventing a large amount of material from accumulating on the moving liner plate 65 and avoiding excessive wear and impact on the moving liner plate 65.

[0023] In this embodiment, a mounting base 3 is fixedly connected to the upper end of the crushing chamber 1. The fixed liner 2 is installed inside the mounting base 3 and is located above the crushing chamber 1. The feed inlet 4 is installed at the upper end of the fixed liner 2. A crushing groove 5 is opened on the inner wall of the fixed liner 2. The moving liner 65 is located inside the fixed liner 2. There is a small gap between the moving liner 65 and the fixed liner 2. The crushing groove 5 and the corresponding crushing groove 66 intersect.

[0024] Specifically, the worker first installs the crushing chamber 1 on the external equipment, and then installs the drive shaft 64 on the drive equipment. Next, the worker aligns the material distribution plate 69 with the connecting rod 67, and secures the internal threaded ring 68 on the outside of the connecting rod 67. Then, the worker rotates the material distribution plate 69 so that the internal threaded ring 68 rotates along the connecting rod 67. Finally, the worker screws the internal threaded ring 68 onto the outside of the connecting rod 67 and makes the internal threaded ring 68 contact the retaining ring 610. The material distribution plate 69 can then be installed above the moving liner 65, thus completing the preliminary preparation work for crushing materials.

[0025] Working principle:

[0026] In use, the worker first installs the crushing chamber 1 on the external equipment, and then installs the drive shaft 64 on the drive equipment. Next, the distributor plate 69 is aligned with the connecting rod 67, and the internal threaded ring 68 is secured to the outside of the connecting rod 67. The distributor plate 69 is then rotated, causing the internal threaded ring 68 to rotate along the connecting rod 67. The internal threaded ring 68 is then screwed onto the outside of the connecting rod 67 and contacts the retaining ring 610. The distributor plate 69 can then be installed above the moving liner plate 65. The drive equipment then drives the drive shaft 64 to rotate within the connecting seat 63, and the drive shaft 64 drives the moving liner plate 65 to rotate within the fixed liner plate 2. This causes the distributor plate 69 to rotate following the moving liner plate 65. At this point, the worker pours the material into the feed inlet 4, ensuring the material contacts the distribution plate 69. The material then slides down the distribution plate 69 in all directions, falling into the gap between the fixed liner plate 2 and the moving liner plate 65. This allows the crushing groove 66 on the outer side of the moving liner plate 65 to engage with the crushing groove 5 on the inner wall of the fixed liner plate 2, thus crushing the material. By pouring the material into the feed inlet 4 and ensuring it contacts the distribution plate 69, the material slides down the surface of the distribution plate 69 in all directions. This facilitates the material falling into the gap between the fixed liner plate 2 and the moving liner plate 65, preventing a large amount of material from accumulating on the moving liner plate 65 and avoiding excessive wear and impact on the moving liner plate 65.
