Description

Technical Field

[0001] This utility model relates to the field of crusher technology, specifically a dustproof ring for a single-cylinder hydraulic cone crusher. Background Technology

[0002] Single-cylinder hydraulic cone crushers are widely used in various ferrous, non-ferrous, and non-metallic mines and sand and gravel industries. Their characteristics, such as high crushing force, high production efficiency, layered crushing, uniform finished product particle shape, low consumption of consumables, and low operating costs, make them an indispensable and important component in the crushing industry. Their principle involves a pair of meshing gears driving an eccentric mechanism to perform an eccentric oscillating motion, which compresses and crushes the material within the crushing chamber.

[0003] Because it is commonly used for crushing minerals and stones, dust inevitably rises from the crushing chamber during operation. This dust flows in two directions: one towards the outside of the crusher, and the other towards the inside, specifically the interior of the dust cover. Once inside, the dust travels with the lubricating oil through the main transmission structures, significantly reducing the lifespan of precision-fitted transmission parts, increasing the frequency of lubricating oil changes, damaging filter elements, and causing a series of losses. This also leads to more frequent equipment downtime for maintenance.

[0004] The traditional dust control method for single-cylinder hydraulic cone crushers is to introduce high-pressure, high-speed airflow through an external blower system. This airflow is then divided into several streams and sprayed upwards from inside the dust cover. However, this only achieves a uniform, vertically upward airflow from inside the dust cover. There is still a distance between the airflow streams, which means that some areas inside the dust cover are not exposed to the airflow. Therefore, although the traditional dust control method is effective, there are still areas inside the dust cover that are not protected by airflow. Dust can enter the dust cover from these areas and mix with the lubricating oil. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this utility model provides a dustproof ring for a single-cylinder hydraulic cone crusher, which solves the problem of dust easily entering the dust cover of the crusher and contaminating the lubricating oil.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dustproof ring for a single-cylinder hydraulic cone crusher, comprising:

[0007] A dustproof ring, which is installed on the dust cover of the cone crusher;

[0008] A dust collection trough is provided on the inner arc surface of the dustproof ring to store dust and prevent dust from entering.

[0009] Furthermore, the outer surface of the dustproof ring is a slope, and the outer side of the dustproof ring extends into the gap between the moving cone and the sealing ring on the cone crusher. The cross-sectional shape of the gap between the moving cone and the sealing ring is the same as the cross-sectional shape of the dustproof ring and is in the same direction.

[0010] Furthermore, the dustproof ring is made of elastic and wear-resistant nylon.

[0011] Furthermore, a dust cover is installed on the frame of the cone crusher, and a main shaft is also installed on the frame. The dust cover surrounds the outside of the main shaft; the moving cone is installed on the main shaft.

[0012] Furthermore, a sealing ring is located at the bottom of the moving cone and is connected by bolts.

[0013] Furthermore, the frame and dust cover are connected by connecting rods.

[0014] Compared with existing technologies, this invention has the following advantages: By setting a dust storage groove on the inner arc surface of the dustproof ring, dust can be stored, preventing dust from entering; by setting the outer side of the dustproof ring as an inclined surface, the length of the dustproof channel can be greatly increased, making it difficult for dust to enter the dustproof cover and contaminate the lubricating oil. Furthermore, when the moving cone moves, the gap between the moving cone and the sealing ring squeezes the inclined surface of the dustproof ring, causing the dustproof ring to quickly adhere to the dustproof cover, reducing the dustproof gap between the dustproof ring and the dustproof cover, making it difficult for dust to enter the dustproof cover through the gap; by using a dustproof ring made of elastic and wear-resistant nylon material, the wear resistance and durability of the dustproof ring can be greatly improved, significantly increasing its service life.

[0018] like Figures 1-2 As shown, this utility model provides a technical solution: a dustproof ring for a single-cylinder hydraulic cone crusher, comprising:

[0019] Dustproof ring 1, which is installed on the dust cover 8 of the cone crusher;

[0020] Dust storage tank 9 is disposed on the inner arc surface of the dustproof ring 1 and is used to store dust and prevent dust from entering.

[0021] The outer surface of the dustproof ring 1 is inclined. The outer side of the dustproof ring 1 extends into the gap between the moving cone 7 and the sealing ring 6 on the cone crusher. The cross-sectional shape of the gap between the moving cone 7 and the sealing ring 6 is the same as the cross-sectional shape of the dustproof ring 1 and is in the same direction. By setting the outer surface of the dustproof ring 1 as inclined, the length of the dustproof channel 10 can be greatly increased, making it difficult for dust to enter the dust cover 8 and contaminate the lubricating oil. When the moving cone 7 moves, the gap between the moving cone 7 and the sealing ring 6 squeezes the inclined surface of the dustproof ring 1, causing the dustproof ring 1 to quickly adhere to the dust cover 8, reducing the dustproof gap 5 between the dustproof ring 1 and the dust cover 8, making it difficult for dust to enter the dust cover 8 through the dustproof gap 5.

[0022] In this embodiment, the cross-section of the dustproof ring 1 and the cross-section of the gap between the moving cone 7 and the sealing ring 6 can be set as "V" shape, with the opening side of the "V" shape facing the dust cover 8. The conical surface of the dustproof ring 1 extends into the gap between the moving cone 7 and the sealing ring 6. By setting the cross-section of the dustproof ring 1 as a "V" shape, the length of the dustproof channel 10 is greatly increased, making it difficult for dust to enter the dust cover 8 and contaminate the lubricating oil. By setting the cross-section of the gap between the moving cone 7 and the sealing ring 6 and the cross-section of the dustproof ring 1 as a "V" shape, when the moving cone 7 moves, the gap between the moving cone 7 and the sealing ring 6 squeezes the inclined surface of the dustproof ring 1, causing the dustproof ring 1 to quickly adhere to the dust cover 8, reducing the dustproof gap 5 between the dustproof ring 1 and the dust cover 8, making it difficult for dust to enter the interior of the dust cover 8 through the dustproof gap 5.

[0023] The surface of the dust collection tank 9 can be arc-shaped.

[0024] The dustproof ring 1 is made of elastic and wear-resistant nylon material, which can greatly improve the wear resistance and durability of the dustproof ring 1, thus significantly increasing its service life.

[0025] The dust cover 8 is installed on the frame 4 of the cone crusher, and the main shaft 3 is also installed on the frame 4. The dust cover 8 surrounds the outer periphery of the main shaft 3; the moving cone 7 is installed on the main shaft 3.

[0026] The sealing ring 6 is located at the bottom of the moving cone 7 and is connected by bolts.

[0027] The frame 4 and the dust cover 8 are connected by a connecting rod 2.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
