Description

Technical Field

[0001] The invention belongs to the field of rotary pendulum crushers, and in particular relates to a composite dust-proof device for a transmission part of a rotary pendulum crusher. Background Art

[0002] At present, the common dust-proof structure of the mainframe of the cone swing crusher is: there is no compensation structure after the inner hole of the dust ring is worn. As the inner hole of the dust ring and the outer ring of the dust cover wear, the gap between them increases, the dust-proof effect is significantly reduced, and dust easily enters the mainframe. The dust ring material is basically phenolic resin or nylon. Their common characteristics are that the dust-proof effect increases with wear, and the dust-proof effect is reduced. Dust easily enters the mainframe, causing the lubricating oil to become dirty, thereby affecting the lubrication effect and life of the main parts such as the eccentric copper sleeve. Frequent replacement of lubricating oil greatly increases the maintenance cost. The bottom of the dust cover will also wear, and the dust ring should be replaced frequently. Summary of the invention

[0003] The purpose of the present invention is to provide a composite dustproof device for the transmission part of a swing crusher, which can greatly increase the service life of the flexible rubber cover, minimize the entry of dust into the main system of the swing crusher, maintain the purity of the main lubricating oil, and reduce maintenance time.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a composite dustproof device for the transmission part of a rotary swing type crusher, comprising a rotary swing cone assembly, a dust cover, and a frame assembly, wherein the lower part of the frame assembly is a lower frame, the rotary swing cone assembly is installed on the lower frame through a main shaft assembly, and the main shaft assembly is driven by an eccentric assembly to drive the rotary swing cone assembly to rotate and swing, the dust cover is sleeved between the rotary swing cone assembly and the lower frame, the dust cover is a flexible rubber cover, the lower part of the flexible rubber cover is fixed to the lower frame through a lower connecting ring, a spherical dust ring is arranged on the upper part of the flexible rubber cover, an upper connecting spherical ring is installed on the moving cone assembly, and the spherical dust ring is pressed against the lower part of the moving cone assembly through the upper connecting spherical ring to form a seal.

[0005] Furthermore, one end of the spherical dust ring is provided with a spherical surface extending outward, and the other end is provided with an anti-rotation groove.

[0006] Furthermore, the facing surfaces of the lower connecting ring and the spherical dust ring are provided with an anti-rotation plate protrusion that cooperates with the anti-rotation groove, and the end of the anti-rotation plate protrusion is inserted into the anti-rotation groove.

[0007] Furthermore, it also includes an auxiliary dustproof structure, which includes a dustproof ring and a groove plate. The groove plate is fixed on the outside of the spherical dustproof ring by long bolts and forms a groove with the upper connecting spherical ring. A dustproof ring connecting ring is provided on the outside of the dustproof ring and is installed on the upper connecting spherical surface through the dustproof ring connecting ring, and the inner side of the dustproof ring is embedded in the groove.

[0008] Furthermore, it also includes a blower, and an air duct connected to the flexible rubber cover is opened in the lower frame, and the air duct is connected to the blower.

[0009] Compared with the prior art, the present invention has the following beneficial effects: 1. The flexible rubber cover is flexible and swings with the spherical dustproof ring, ensuring that the spherical dustproof ring can be close to the upper connecting spherical ring and the moving cone assembly in real time, effectively ensuring the reliability of the seal. 2. The anti-rotation groove is stuck in the anti-rotation plate convex plate of the lower connecting ring to limit its rotation, and the flexible rubber cover on the protective connection can only rotate in a small range in the anti-rotation groove when swinging, so that the pulling on the flexible rubber cover caused by its rotation is limited, greatly extending the service life of the flexible rubber cover. 3. The dustproof ring is an auxiliary dustproof structure, and its material is rubber. Through the auxiliary dustproof structure of the dustproof ring, the dust entering the main unit is greatly reduced, further enhancing the dustproof effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0016] Reference Figure 1-3 A composite dust-proof device for the transmission part of a rotary swing type crusher comprises a rotary swing cone assembly 2, a dust cover, and a frame assembly 1. The lower part of the frame assembly 1 is a lower frame 3. The rotary swing cone assembly 2 is installed on the lower frame 3 through a main shaft assembly, and the main shaft assembly is driven by an eccentric assembly to drive the rotary swing cone assembly 2 to rotate and swing. The dust cover is sleeved between the rotary swing cone assembly 2 and the lower frame 3. The dust cover is a flexible rubber cover 19. The lower part of the flexible rubber cover 19 is fixed to the lower frame 3 through a lower connecting ring 23 and a lower connecting ring screw 22. The flexible rubber cover 19 The lower end is fixedly connected to the lower connecting ring 23 through the lower connecting screw 20 of the flexible rubber cover in cooperation with the lower connecting washer 21. A spherical dust ring 13 is arranged on the upper part of the flexible rubber cover 19. The upper part of the flexible rubber cover 19 is fixedly connected to the spherical dust ring 13 through the inner bolt 24, the outer bolt 25 and the long connecting nut 26. The upper connecting spherical ring 11 is installed on the moving cone assembly. The upper connecting spherical ring 11 is fixedly connected to the moving cone assembly through the upper connecting spherical ring screw 12. The spherical dust ring 13 is pressed against the lower part of the moving cone assembly through the upper connecting spherical ring 11 to form a seal. Therefore, when the swing crusher is working, the swing cone assembly 2 will drive the upper connected spherical ring 11 to move together. Under the action of friction, the spherical dust ring 13 will swing along the spherical surface A, and the flexible rubber cover 19 is flexible and swings along with the spherical dust ring 13, ensuring that the spherical dust ring 13 can be close to the upper connected spherical ring 11 and the moving cone assembly in real time, effectively ensuring the reliability of the seal.

[0017] Among them, one end surface of the spherical dust ring 13 extends outwardly and is provided with a spherical surface 132, and the other end surface is provided with an anti-rotation groove 131. The spherical dust ring 13 is provided with a countersunk hole 133, which is used to fix the upper end of the flexible rubber cover 19 with the inner bolt 24 and the outer bolt 25. The spherical dust ring 13 is made of wear-resistant nylon to increase the service life and replacement cycle.

[0018] Among them, the facing surfaces of the lower connecting ring 23 and the spherical dust ring 13 are provided with an anti-rotation plate protrusion 231 that cooperates with the anti-rotation groove slot 131, and the end of the anti-rotation plate protrusion 231 is inserted into the anti-rotation groove slot 131. A connecting hole 232 is opened on the lower connecting ring 23, and the connecting hole 232 is used to fix the lower end of the flexible composite dustproof device with the lower frame 3 using the lower connecting ring 23 bolts.

[0019] In order to prevent the rotating and swinging cone assembly 2 from rotating when swinging, which may cause the flexible rubber cover 19 to tear due to fatigue caused by long-term stress, when the rotating and swinging cone assembly 2 swings, the anti-rotation groove 131 is stuck in the anti-rotation plate convex plate 231 of the lower connecting ring 23, limiting its rotation, and protecting the flexible rubber cover 19 on the connection so that it can only rotate in a small range in the anti-rotation groove 131 when swinging, so that the pulling on the flexible rubber cover 19 caused by its rotation is limited, and the flexible rubber cover 19 of the flexible composite dustproof device realizes the up and down movement between the moving cone and the main machine, and the flexible rubber cover 19 is prevented from being subjected to large torque by the anti-rotation groove 131 of the spherical dustproof ring 13 and the anti-rotation plate convex plate 231 of the lower connecting ring 23, thereby greatly extending the service life of the flexible rubber cover 19.

[0020] Among them, it also includes an auxiliary dustproof structure, which includes a dustproof ring 17 and a groove plate 18. The groove plate 18 is fixedly sleeved on the outside of the spherical dustproof ring 13 by long bolts, and forms a groove with the upper connecting spherical ring 11. A dustproof ring connecting ring 14 is arranged on the outside of the dustproof ring 17. The dustproof ring 17 and the dustproof ring connecting ring 14 are fixedly connected by rivets 16 and are installed on the upper connecting spherical surface through the dustproof ring connecting ring 14. The dustproof ring connecting ring 14 and the upper connecting spherical surface are fixedly connected by dustproof ring connecting ring screws 15. The inner side of the dustproof ring 17 is embedded in the groove. The dustproof ring 17 is an auxiliary dustproof structure, and its material is rubber. Through the auxiliary dustproof structure of the dustproof ring 17, the dust entering the main unit is greatly reduced, thereby further enhancing the dustproof effect.

[0021] The blower is also included, and the lower frame 3 is provided with an air duct 5 connected to the flexible rubber cover 19, and the air duct 5 is connected to the blower. The blower assembly 4 is connected to the air duct 5 through a hose and a joint, and transmits positive air pressure to the inner cavity of the crusher, forming a positive air pressure dustproof effect, and blocking dust outside the inner cavity of the crusher.

[0022] The present invention uses a flexible rubber cover 19 to achieve a seamless flexible connection between the swing cone assembly 2 and the cone swing crusher main unit; the anti-rotation groove 131 card design greatly increases the service life of the flexible rubber cover 19, and achieves that the flexible rubber cover 19 is restricted by the anti-rotation groove 131 card during the swinging process, thereby avoiding bearing a large rotational torque and achieving an efficient dust-proof effect for the swing crusher main unit, greatly increasing the service life of the flexible rubber cover 19, and minimizing the dust from entering the swing crusher main unit system, providing the swing crusher main unit with high-purity lubricating oil, greatly extending the oil change time, and effectively ensuring the core transmission parts' need for high-purity lubricating oil.

[0023] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
