DETAILED DESCRIPTION

[0026] The following are specific embodiments of the present invention, and the technical solution of the present invention is further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0027] like Figure 1-6As shown, a crusher anti-retraction copper plate structure comprises an adjusting cylinder 4, an adjusting cylinder cover 1 is provided at the bottom of the adjusting cylinder 4, a fixing seat 13 is provided inside the adjusting cylinder 4, an adjusting piston 2 is provided between the fixing seat 13 and the adjusting cylinder cover 1, an oil delivery groove 14 is provided between the fixing seat 13 and the adjusting piston 2, a bushing 3 is provided on the side wall of the adjusting cylinder 4, an adjusting bolt 5 is provided between the adjusting cylinder cover 1 and the adjusting piston 2, the adjusting bolt 5 passes through the adjusting cylinder cover 1 and is connected with the adjusting piston 2, a locking nut 1010 is threadedly connected to the lower part of the adjusting bolt 5, and the locking nut 1010 can thread-lock the adjusting bolt 5 after the adjusting piston 2 completes the supply of lubricating oil, a lower anti-retraction copper plate 9 is provided on the fixing seat 13, a anti-retraction gasket 8 is provided on the upper part of the lower anti-retraction copper plate 9, an upper anti-retraction copper plate 7 is provided on the upper part of the anti-retraction gasket 8, and the upper end of the upper anti-retraction copper plate 7 is connected to the main shaft assembly 6 through a retaining spring.

[0028] Among them, the bushing 3 is sealed and connected with the adjusting cylinder 4, and the adjusting piston 2, bushing 3 and fixed seat 13 form a sealed oil chamber. The adjusting piston 2 can slide up and down in the sealed oil chamber. The adjusting bolt 5 is threadedly connected with the adjusting piston 2. By rotating the adjusting bolt 5 outside the adjusting cylinder cover 1, the adjusting piston 2 can be controlled to slide up and down.

[0029] The adjusting piston 2, bushing 3 and fixing seat 13 form a sealed oil chamber, which ensures the sealing of the oil chamber and can ensure that lubricating oil can be provided to the anti-retraction copper disk structure in a timely and sufficient manner. When lubricating oil is needed, the adjusting bolt 5 can be rotated to push the adjusting piston 2 upward through the threaded connection to push the lubricating oil in the oil chamber into the anti-retraction copper disk structure through the oil delivery groove 14.

[0030] The upper stop copper plate 7 includes a left half 701 and a right half 702 , and the left half 701 and the right half 702 are asymmetrical structures.

[0031] By adopting an asymmetric structural design, when the main shaft assembly 6 is running, the upper stop copper plate 7 that needs to be subjected to force is in full contact with the stop gasket 8, so that the force on the upper stop copper plate 7 is more evenly distributed; the side that is not subjected to force and is not in contact can allow the lubricating oil to fully contact with it, which is more conducive to lubrication, thereby avoiding the burning of the upper stop copper plate 7 due to lack of oil, reducing the vibration of the equipment and increasing the service life of the equipment.

[0032] A plurality of mutually overlapping annular lubricating oil grooves 12 are disposed on the upper portion of the upper copper stop plate 7 and the upper portion of the lower copper stop plate 9 , and a through hole 11 is disposed at the center of the upper copper stop plate 7 and the lower copper stop plate 9 .

[0033] A lubricating oil groove 12 is set on the upper part of the upper stop copper plate 7 and the upper part of the lower stop copper plate 9. When the lubricating oil liquid is input into the lubricating oil groove 12 through the oil supply groove 14, the upper stop copper plate 7 and the lower stop copper plate 9 can be lubricated in all directions. At the same time, the lubricating oil groove 12 can also play the role of storing a part of the lubricating oil. A through hole 11 is set at the center of the upper stop copper plate 7, the stop gasket 8 and the lower stop copper plate 9, which can ensure that the lubricating oil liquid is smoothly input into the upper stop copper plate 7, the stop gasket 8 and the lower stop copper plate 9.

[0034] Among them, a through hole 11 is provided at the center of the anti-retreat gasket 8, an oil groove 801 is provided in the middle and lower part of the anti-retreat gasket 8, and two annular grooves 803 are provided in the upper part of the anti-retreat gasket 8. The cross-section of the oil groove 801 is a cross-shaped structure, and the through hole 11 vertically passes through the center of the oil groove 801 to form a hollow structure. The outer end of the oil groove 801 extends outward to the outermost layer of the annular groove 803 and is connected with the bottom of the two annular grooves 803. Balls 802 are installed on the upper part of the connection between the oil groove 801 and the bottom of the annular groove 803. The ball 802 is slightly higher than the upper plane of the anti-retreat gasket 8, and the ball 802 is embedded in the annular groove 803 and can rotate in the annular groove 803.

[0035] By adopting the matching structure of setting the oil groove 801, the annular groove 803 and the ball 802 inside the anti-retraction gasket 8, the lubricating oil can enter the oil groove 801 and the annular groove 803 through the through hole 11. The upper anti-retraction copper plate 7 is driven by the operation of the main shaft assembly 6 to contact the ball 802 on the anti-retraction gasket 8, driving the ball 802 to rotate. When the ball 802 contacts and rotates with the upper anti-retraction copper plate 7, the lubricating oil in the annular groove 803 can be brought into the upper anti-retraction copper plate 7, which plays a role in continuous lubrication of the upper anti-retraction copper plate 7, greatly The lubrication effect is improved and the service life of the cone crusher is further prolonged. In addition, the ball 802 is designed to be slightly higher than the upper plane of the anti-retreat gasket 8. On the one hand, it can ensure that the upper anti-retreat gasket 8 can be fully lubricated by the lubricating oil under the action of the ball 802. On the other hand, it can also reduce the friction between the upper anti-retreat copper plate 7 and the anti-retreat gasket 8 by rolling, so that the upper anti-retreat gasket 8 can run more smoothly. The design method of being slightly higher than the upper plane of the anti-retreat gasket 8 further ensures the stability of the operation of the upper anti-retreat gasket 8 and makes the force more uniform.

[0036] Among them, oil-absorbing cotton 804 is arranged inside the annular groove 803, and the end of the oil-absorbing cotton 804 is squeezed and connected with the ball 802. The oil-absorbing cotton 804 can store more lubricating oil. At the same time, the end of the oil-absorbing cotton 804 and the ball 802 form a squeezing effect, and more lubricating oil can also be added to the ball 802 when the ball 802 rotates.

[0037] The regulating oil cylinder cover 1, the fixing seat 13 and the regulating oil cylinder 4 are all sealed and connected, which can ensure that the regulating piston 2 can quickly complete the lubricating oil delivery work in a sealed state.

[0038] The working principle of the utility model is as follows:

[0039] When the utility model needs to add lubricating oil, the adjusting bolt 5 is manually turned, and the adjusting piston 2 is pushed upward through the threaded connection to push the lubricating oil in the oil chamber into the anti-retraction copper plate structure through the oil delivery groove 14 and the through hole 11. At the same time, the lubricating oil groove 12 of the upper anti-retraction copper plate 7 and the lower anti-retraction copper plate 9 can also store some lubricating oil, and the lubricating oil will also be stored by entering the oil groove 801 and the annular groove 803 on the anti-retraction gasket 8. When the main shaft assembly 6 drives the upper anti-retraction copper plate 7 to move, the bottom of the upper anti-retraction copper plate 7 contacts the ball 802 on the anti-retraction gasket 8, driving the corresponding ball 802 to move, and the lubricating oil on the ball 802 is also brought to the upper anti-retraction copper plate 7 and enters the lubricating oil groove 12. At the same time, the upper anti-retraction copper plate 7 that needs to be subjected to force can fully contact with the anti-retraction gasket 8, and the force is more uniform, which enhances the working stability. At the same time, since the upper anti-retraction copper plate 7 is non Symmetrical structure, the lubricating oil will flow to the side of the upper stop copper plate 7 that is not stressed due to the extrusion force, and sufficiently lubricate the upper stop copper plate 7 and the stop gasket 8, thereby avoiding the burning of the upper stop copper plate 7 due to lack of oil, reducing the vibration of the equipment and increasing the service life of the equipment. In addition, oil-absorbing cotton 804 can also be added in the annular groove 803. The oil-absorbing cotton 804 can store more lubricating oil. At the same time, the end of the oil-absorbing cotton 804 forms an extrusion effect with the ball 802, and more lubricating oil can be added to the ball 802 when the ball 802 rotates, thereby further improving the lubrication effect. When there is no need to add lubricating oil, the locking nut 10 at the end of the rotating adjusting bolt is locked to the adjusting bolt 5, thereby avoiding the influence of the vibration caused by the movement of the main shaft assembly 6 on the position of the adjusting bolt 5, and ensuring that the lubricating oil can be provided to the stop copper plate in a sufficient, stable and continuous manner.

[0040] In general, the utility model has a reasonable design, ensures uniform force and good lubrication effect of the upper stop copper plate 7, reduces the vibration amount during equipment operation, enhances working stability, and increases the service life of the equipment.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above 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 utility model shall be included in the protection scope of the utility model.
