Technical Field

[0001] The utility model relates to the technical field of crusher equipment, in particular to a mantle for a cone crusher. Background Art

[0002] The mantle is an important accessory of a cone crusher, which together with the frame, horizontal shaft, moving cone, balance wheel, eccentric bushing, lower crushing wall, hydraulic coupling, lubrication system, hydraulic system, and control system constitutes a cone crusher; large-sized crushed stones are gradually crushed from top to bottom after passing through the inner cavity formed by the mantle and the crushing wall, and small-sized crushed stones are produced when exiting from the discharge port.

[0003] During the operation of the existing cone crusher, the stone material will be crushed into small stones by extrusion on the inner surface of the conical mantle, resulting in extremely high impact force and large wear on the mantle, leading to the problem of short service life of the existing mantle.

[0004] Existing patent (Publication No.: CN216799952U) A mantle for a cone crusher with a long service life, by arranging a damper between the fixed block and the connecting block, enables the main body in the crushing work to offset and buffer the impact force when bearing the impact force of the stone material, and reduces the impact wear on the crushing cavity. At the same time, the damper can also absorb the vibration generated by the main body during the crushing process and reduce the noise generated during operation.

[0005] In view of the above problems, the existing patent gives a solution, but there are still certain limitations in its working process. Although the above patent can absorb vibration through the damper, it will cause certain damage to the damper during the absorption process, and the damper is a relatively delicate instrument, and the damper is prone to damage after long-term work, which will reduce the practicability of the mantle. Summary of the Invention

[0006] The purpose of the utility model is to provide a mantle for a cone crusher, which can solve the problem of poor practicability of the mantle.

[0007] To achieve the above purpose, the utility model provides the following technical solution: A mantle for a cone crusher, including a mantle body, a cavity is opened on the mantle body, an elastic membrane is fixedly installed in the cavity, a counterweight block is fixedly installed on the elastic membrane, and air holes communicating with the outside are evenly opened on the cavity.

[0008] Preferably, grinding rods are evenly inserted on the inner wall of the mantle body, an impact plate is fixedly installed at one end of the grinding rod away from the elastic membrane, and a limiting plate is fixedly installed at one end of the grinding rod close to the elastic membrane.

[0009] Preferably, a collection box for collecting pulverized dust is provided on the main body of the crushing wall, and a collection pipe communicating with the main body of the crushing wall is inserted into the wall of the collection box.

[0010] Preferably, an exhaust valve is inserted into the air hole, and an intake valve communicating with the connecting pipe is inserted into the side wall of the main body of the crushing wall.

[0011] Preferably, a filter screen for filtering dust is provided in the collection box, the collection pipe is located below the filter screen, and the connecting pipe is located above the filter screen.

[0012] Preferably, a sound insulation cover is sleeved outside the main body of the crushing wall.

[0013] Preferably, a cleaning groove is formed in the bottom wall of the collection box, a sealing plate is hinged in the cleaning groove, a fixing groove is fixedly installed on the side wall of the cleaning groove, and a fixing rod is slidably installed on the sealing plate.

[0014] Preferably, a first magnet and a second magnet that attract each other are respectively embedded in the fixing rod and the fixing groove.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] 1. By arranging the elastic membrane in this application, during the working process of the crusher, the main body of the crushing wall will be driven to vibrate, and then the main body of the crushing wall will transfer the vibration to the elastic membrane, and then transfer it to the counterweight block through the elastic membrane. Then the counterweight block vibrates back and forth, driving the elastic membrane to stretch and contract. During the stretching and contracting process of the elastic membrane, the air in the cavity can be driven to flow, thereby converting the kinetic energy during vibration into cavity air intake and exhaust, reducing the energy during the vibration of the crusher, reducing the vibration of the main body of the crushing wall while also reducing noise, and further improving the practicability of the main body of the crushing wall;

[0017] 2. By arranging the collection box in this application, during the process of the counterweight block driving the elastic membrane to stretch towards the inner side of the crushing wall body, the pressure in the cavity located in the space outside the elastic membrane close to the outer side of the crushing wall body decreases. At this time, under the action of the pressure, the cavity inhales air from the collection box through the intake valve and the connecting pipe, and then the collection box inhales air from the inside of the crushing wall body through the collection pipe. During the process of the collection box inhaling air from the inner side of the crushing wall body through the collection pipe, the dust on the inner side of the crushing wall body flows into the collection box along with the airflow, thereby collecting the dust, improving the safety of the user, and reducing the safety hazard of the user.

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0027] Please refer to Figures 1 to 5 , the present invention provides a technical solution:

[0028] A crushing wall for a cone crusher, including the main body 1 of the crushing wall, a cavity 2 is provided on the main body 1 of the crushing wall, an elastic membrane 3 is fixedly installed in the cavity 2, a counterweight 4 is fixedly installed on the elastic membrane 3, and air holes communicating with the outside are uniformly provided on the cavity 2.

[0029] The inner wall of the crushing wall body 1 is evenly inserted with grinding rods 5. One end of the grinding rod 5 away from the elastic membrane 3 is fixedly installed with an impact disc 6, and one end of the grinding rod 5 close to the elastic membrane 3 is fixedly installed with a limiting plate 7.

[0030] During use, the item to be crushed is placed into the crushing wall body 1 for crushing. During the operation of the crusher, it will drive the crushing wall body 1 to vibrate. Then the crushing wall body 1 transmits the vibration to the elastic membrane 3, and through the elastic membrane 3 to the counterweight 4. Then the counterweight 4 vibrates back and forth, driving the elastic membrane 3 to contract and expand. During the process of the elastic membrane 3 contracting and expanding, it can drive the air flow in the cavity 2, and then the kinetic energy during vibration can be converted into the air intake and exhaust of the cavity 2, thereby reducing the energy during the vibration of the crusher, reducing the vibration of the crushing wall body 1 while also reducing noise, and further improving the practicality of the crushing wall body 1.

[0031] When the counterweight 4 drives the elastic membrane 3 to move towards the outside of the crushing wall body 1, the pressure in the space of the cavity 2 located on the inner side of the elastic membrane 3 close to the crushing wall body 1 decreases. Then under the action of the pressure, the grinding rod 5 moves into the cavity 2. When the counterweight 4 drives the elastic membrane 3 to move towards the inside of the crushing wall body 1, the pressure in the space of the cavity 2 located on the outside of the elastic membrane 3 away from the inner side of the crushing wall body 1 increases. Then under the action of the pressure, the grinding rod 5 drives the impact disc 6 to move towards the inside of the crushing wall body 1. At this time, the impact disc 6 can impact the object to be crushed, and at the same time can also increase the friction of the object to be crushed, thereby improving the crushing efficiency and playing a role in improving the practicality of the crushing wall body 1.

[0032] Specifically, as Figure 2 、 Figure 3 、 Figure 4 shown, a collection box 8 for collecting crushed dust is provided on the crushing wall body 1, and a collection pipe 11 communicating with the crushing wall body 1 is inserted on the wall of the collection box 8.

[0033] An exhaust valve 12 is inserted in the air hole, and an intake valve 9 communicating with the connecting pipe 13 is inserted on the side wall of the crushing wall body 1.

[0034] A filter screen 10 for filtering dust is provided in the collection box 8, and the collection pipe 11 is located below the filter screen 10, and the connecting pipe 13 is located above the filter screen 10.

[0035] A sound insulation cover 14 is sleeved outside the crushing wall body 1.

[0036] By adopting the above technical solution, during the process of crushing stones, there will be fine particulate dust, and then the dust is easily inhaled into the body by the user, which will bring great discomfort to the user. During the process of the counterweight 4 driving the elastic membrane 3 to stretch towards the inner side of the crushing wall body 1, the pressure in the cavity 2 located in the space of the elastic membrane 3 close to the outer side of the crushing wall body 1 decreases. At this time, under the action of the pressure, the cavity 2 inhales air from the collection box 8 through the air inlet valve 9 and the connecting pipe 13, and then the collection box 8 inhales air from the inside of the crushing wall body 1 through the collection pipe 11. During the process of the collection box 8 inhaling air from the inner side of the crushing wall body 1 through the collection pipe 11, the dust on the inner side of the crushing wall body 1 flows into the collection box 8 along with the air flow, so that the dust can be collected, thereby improving the safety of the user and playing a role in reducing the safety hazards of the user.

[0037] After the dust flows into the collection box 8, the dust will be blocked below the filter screen 10, effectively preventing the dust from entering the cavity 2 and affecting the normal stretching of the elastic membrane 3, playing a role in ensuring the normal operation of the device.

[0038] By setting the sound insulation cover 14, the noise generated during the operation of the crusher can be reduced, playing a role in reducing noise.

[0039] Specifically, as Figure 4 shown, a cleaning groove is formed in the bottom wall of the collection box 8, a blocking plate 15 is hinged in the cleaning groove, a fixing groove is fixedly installed on the side wall of the cleaning groove, and a fixing rod 16 is slidably installed on the blocking plate 15.

[0040] A first magnet 17 and a second magnet 18 that attract each other are respectively embedded in the fixing rod 16 and the fixing groove.

[0041] By adopting the above technical solution, after using for a period of time, the user can first push the fixing rod 16 to be separated from the fixing groove, then open the blocking plate 15, and clean the dust in the collection box 8, playing a role in facilitating the cleaning of the dust; and when the user finishes cleaning, the user can push the fixing rod 16 into the fixing groove. At this time, under the suction force between the first magnet 17 and the second magnet 18, the fixing rod 16 and the fixing groove are attracted together, effectively preventing the fixing rod 16 from being separated from the fixing groove during the operation of the collection box 8, playing a role in ensuring the normal operation of the collection box 8.

[0042] Working principle: When in use, the item to be crushed is placed into the mantle body 1 for crushing. During the operation of the crusher, it will drive the mantle body 1 to vibrate. Then the mantle body 1 transmits the vibration to the elastic membrane 3, and through the elastic membrane 3 to the counterweight 4. Then the counterweight 4 vibrates back and forth, driving the elastic membrane 3 to stretch and contract. During the stretching and contraction process of the elastic membrane 3, it can drive the air flow in the cavity 2, thereby converting the kinetic energy during vibration into the suction and exhaust of the cavity 2, reducing the energy during the vibration of the crusher, and reducing the vibration of the mantle body 1 while also reducing noise; when the counterweight 4 drives the elastic membrane 3 to move outward from the mantle body 1, the pressure in the space of the cavity 2 inside the elastic membrane 3 close to the inner side of the mantle body 1 decreases. Then under the action of the pressure, the grinding rod 5 moves into the cavity 2. When the counterweight 4 drives the elastic membrane 3 to move into the mantle body 1, the pressure in the space of the cavity 2 outside the elastic membrane 3 away from the inner side of the mantle body 1 increases. Then under the action of the pressure, the grinding rod 5 drives the impact plate 6 to move into the mantle body 1. At this time, the impact plate 6 can impact the object to be crushed and also increase the friction force of the object to be crushed; during the process of the counterweight 4 driving the elastic membrane 3 to stretch inward from the mantle body 1, the pressure in the space of the cavity 2 inside the elastic membrane 3 close to the outer side of the mantle body 1 decreases. At this time, under the action of the pressure, the cavity 2 sucks air from the collection box 8 through the intake valve 9 and the connecting pipe 13. Then the collection box 8 sucks air from the mantle body 1 through the collection pipe 11. During the process of the collection box 8 sucking air from the inner side of the mantle body 1 through the collection pipe 11, the dust on the inner side of the mantle body 1 flows into the collection box 8 along with the air flow, thereby collecting the dust; after using for a period of time, the user can first push the fixed rod 16 to disengage from the fixed groove, then open the blocking plate 15, and clean the dust in the collection box 8, which plays a role in facilitating the cleaning of the dust; and when the user finishes cleaning, the user can push the fixed rod 16 into the fixed groove. At this time, under the suction force between the first magnet 17 and the second magnet 18, the fixed rod 16 and the fixed groove are attracted together, effectively preventing the fixed rod 16 from disengaging from the fixed groove during the operation of the collection box 8.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
