Description

Technical Field

[0001] This utility model relates to the technical field of sealing components for multi-cylinder cone crushers, specifically a dustproof sealing assembly for a multi-cylinder cone crusher. Background Technology

[0002] The multi-cylinder cone crusher is a crushing equipment applicable to multiple industries. It evolved from the spring cone crusher, and its basic structure is similar, except that the original multiple springs are replaced with multiple hydraulic cylinders. Dustproof sealing components are mainly used between relatively moving parts in the multi-cylinder cone crusher. Common dustproof sealing structures consist of I-shaped sealing rings and irregularly shaped sealing rings.

[0003] During operation, the core moving components of a multi-cylinder cone crusher, such as the internal eccentric copper sleeve, rely on lubricating oil for lubrication and cooling. However, the working environment is typically harsh and dusty. If dust enters the oil passages, it will contaminate the lubricating oil, leading to rapid wear of the internal core components, reducing the equipment's lifespan and performance, and increasing maintenance costs and downtime. Therefore, a flexible contact sealing structure is adopted to prevent dust from entering the crusher.

[0004] A search revealed that Chinese patent document CN222458363U discloses a dustproof sealing structure for a multi-cylinder cone crusher, including a moving cone and a balance ring. A labyrinth seal structure is provided between the moving cone and the balance ring. The labyrinth seal structure includes a sealing element and a first sealing ring groove provided on the moving cone. A second sealing ring groove is provided at the bottom of the first sealing ring groove. The upper part of the sealing element is provided in the second sealing ring groove. A third sealing ring groove is provided at the top of the balance ring and is adapted to the lower part of the sealing element. The lower part of the sealing element is inserted into the third sealing ring groove.

[0005] The aforementioned patent documents disclose that by using an I-shaped sealing ring, the installation difficulty and the amount of adhesive used can be reduced. However, in actual use, after a long period of use, the I-shaped sealing ring may delaminate, which can easily cause it to fall off and affect the use of the device. Therefore, how to prevent the sealing ring from falling off is an urgent problem to be solved. Utility Model Content

[0029] Specifically, the sealing ring 1 includes an upper part 101, a middle part 102, and a lower part 103. The upper part 101, the middle part 102, and the lower part 103 are arranged from top to bottom. The upper part 101 and the lower part 103 have vertical cross sections, the middle part 102 has a horizontal cross section, and the sealing ring 1 has a cross-shaped cross section. The inner and outer walls of the middle part 102 are respectively provided with a second protrusion 12. When the sealing ring 1 is engaged in the moving cone 14, and the second protrusion 12 fits against the moving cone 14, the connection effect between the sealing ring 1 and the moving cone 14 is improved.

Glue can be applied to the empty space in the outer mounting groove 11 to limit the connection between the inner and outer limiting strips 16, thereby improving the connection effect of the sealing ring 1 connection end and playing a reinforcing role.

[0034] The working principle and usage process of this utility model are as follows: Before use, insert the inner limiting strip 16 into the inner mounting groove 11. The connecting block 17 passes through the sealing ring 1 and extends to the outer mounting groove 11. Insert the outer limiting strip 16 into the upper position of the outer mounting groove 11. Then, move the outer limiting strip 16 down in the outer mounting groove 11 so that the connecting block 17 gradually connects with the groove. The locking strip 18 is inserted into the dovetail groove on the connecting block 17 until the outer limiting strip 16 can no longer move down and stops moving. Apply glue to the empty space of the outer mounting groove 11, and then it can be used.

[0035] In use, the sealing ring 1 is inserted into the moving cone 14, and the guide groove 13 is slidably connected to the moving cone 14 to limit and guide the sealing ring 1, thereby facilitating the quick and easy location of the corresponding installation position of the elastic block 2. During this process, the second convex ring 12 is in contact with the moving cone 14, and the elastic block 2 is inserted into the moving cone 14. The threaded rod 4 is screwed in with a screwdriver until it is fully screwed into the second connecting groove 9. During the screwing process, the push block 3 is pushed upward, gradually pushing the elastic blocks 2 on both sides. The elastic blocks 2 rotate outward, so that the elastic blocks 2 are engaged with the moving cone 14. After screwing, the plug 5 is inserted into the first connecting groove 8 to cover the threaded rod 4, and the bottom ring 6 is in contact with the bottom of the sealing ring 1.
