Technical Field

[0001] The utility model relates to the technical field of cone crushers, and in particular to a safe cone crusher. Background Art

[0002] A cone crusher is a crushing machine suitable for raw materials in the metallurgical, construction, road construction, chemical, and silicate industries. During the operation of the cone crusher, the body has a very high rotational speed before no material enters the equipment. In related technologies, speed limiting is mostly carried out by abutting a contact piece against the body, and the rotational speed can be controlled at about 1 / 2 of the rotational speed of the eccentric sleeve. However, even such a rotational speed will cause a very large extrusion force on the bushing on the body, and in extreme working conditions, accidents such as runaway and bushing burning may occur, affecting the safety of production. Therefore, improvement is needed. Content of the Utility Model

[0003] In order to limit the rotational speed of the body, reduce the occurrence of production accidents, and improve the safety of using the crusher, the present application provides a safe cone crusher.

[0004] The safe cone crusher provided by the present application adopts the following technical solutions:

[0005] A safe cone crusher includes a housing and a body rotatably arranged on the housing. A damping ring is installed on the housing. The length of the damping ring is arranged along the circumferential direction of the body. The surface of the damping ring abuts against the surface of the body. An annular groove is arranged on the surface of the damping ring for storing lubricating grease. The damping ring is made of polyurethane material.

[0006] By adopting the above technical solutions, when the body rotates, the damping ring made of polyurethane material abuts against the surface of the body, increasing the contact area with the body. At the same time, the damping ring has a high hardness, significantly reducing the rotational speed of the body. At the same time, the situation of dust entering the crusher is reduced. The lubricating grease in the annular groove can lubricate the surface of the damping ring, which is beneficial to extending the service life of the damping ring, ensuring that there is a certain pressure between the body and the damping ring after installation, forming sufficient friction to reduce the rotational speed, and thus reducing the phenomenon of bushing burning on the body and improving the safety of using the crusher.

[0007] Preferably, an oil inlet pipe and an oil outlet pipe are arranged on the side wall of the damping ring. Both the oil inlet pipe and the oil outlet pipe are communicated with the annular groove, and valves are arranged on the oil inlet pipe and the oil outlet pipe.

[0008] By adopting the above technical solutions, after the damping ring is used for a long time, the lubricating grease in the annular groove can be replaced through the oil inlet pipe and the oil outlet pipe to ensure a good lubricating effect on the damping ring.

[0010] By adopting the above technical solution, when the damping ring is subjected to the pressure of the body, the buffer spring abuts against the bottom wall of the installation ring, and the installation ring can slide in the installation groove, giving the damping ring a certain space for yielding. Furthermore, the buffer spring can play a buffering role on the damping ring, which is beneficial to extending the service life of the damping ring and reducing the situation that the damping ring is damaged due to excessive pressure from the body.

[0011] Preferably, a plurality of guide rods are arranged in the installation groove, and guide grooves for inserting and sliding the guide rods are formed on the bottom wall of the installation ring. The guide grooves and the guide rods are mutually adapted, and the buffer springs are sleeved on the guide rods.

[0012] By adopting the above technical solution, when the installation ring slides in the installation groove under buffering, the guide rods play a guiding role on the installation ring. The guide rods slide in the guide grooves and limit the buffer springs at the same time, reducing the phenomenon that the buffer springs are offset and bent.

[0013] Preferably, a plurality of connection holes are penetrated through the bottom wall of the installation groove, connection blocks are threadedly connected in the connection holes, the guide rods are fixedly arranged on the connection blocks, and the buffer springs can pass through the connection holes.

[0014] By adopting the above technical solution, rotate the connection block to separate the connection block from the connection hole. At this time, the guide rod can be taken out of the installation groove, and then the buffer spring can be taken out of the installation groove through the connection hole, so that the buffer spring can be replaced to ensure that the buffer spring has a good abutting effect on the installation ring and is convenient for maintaining the equipment.

[0017] Preferably, a plurality of installation bolts are penetrated through the installation seat, and the installation bolts are threadedly connected with the housing.

[0018] By adopting the above technical solution, the detachable connection between the mounting seat and the housing is realized by using the mounting bolts, and the mounting seat can be disassembled conveniently for the installation, replacement and maintenance of the damping ring.

[0019] Preferably, a bending part is arranged between the mounting ring and the damping ring, and the bending part is integrally formed with the mounting ring and the damping ring.

[0021] In summary, the present application includes at least one of the following beneficial technical effects:

[0022] 1. By arranging the damping ring and the annular groove, when the body rotates, the damping ring made of polyurethane material abuts against the surface of the body, increasing the contact area with the body, significantly reducing the rotation speed of the body, and at the same time reducing the situation of dust entering the crusher.

[0028] The following will further elaborate on this application Figure 1-2 in conjunction with the attached drawings.

[0029] An embodiment of this application discloses a safe cone crusher. Referring to Figure 1 and Figure 2 , it includes a housing 1 and a body 11 rotatably arranged on the housing 1. A damping ring 2 is installed on the housing 1. The length of the damping ring 2 is arranged along the circumferential direction of the body 11, and the damping ring 2 abuts against the surface of the body 11. When the body 11 rotates self - rotatably, the damping ring 2 made of polyurethane material abuts against the surface of the body 11, increasing the contact area with the body 11. At the same time, the damping ring 2 has a relatively high hardness, significantly reducing the self - rotation speed of the body 11 and reducing the situation of dust entering the crusher. An annular groove 21 is provided on the surface of the damping ring 2. The length direction of the annular groove 21 is arranged along the circumferential direction of the damping ring 2. The annular groove 21 is used to store lubricating grease. When the body 11 rotates on the damping ring 2, the lubricating grease in the annular groove 21 can lubricate the surface of the damping ring 2, which is beneficial to extending the service life of the damping ring 2, ensuring that there is a certain pressure between the body 11 and the damping ring 2 after installation, forming sufficient frictional force to reduce the speed, and thus reducing the phenomenon of bushing burning on the body 11 and improving the safety of the crusher during use.

[0030] Referring to Figure 1 , an inlet oil pipe 31 and an outlet oil pipe 32 are provided on the side wall of the damping ring 2. The inlet oil pipe 31 and the outlet oil pipe 32 are located on both sides of the damping ring 2. Both the inlet oil pipe 31 and the outlet oil pipe 32 are in communication with the annular groove 21. Valves are provided on the inlet oil pipe 31 and the outlet oil pipe 32. The lubricating grease in the annular groove 21 is sucked away through the outlet oil pipe 32, and at the same time, new lubricating grease enters through the inlet oil pipe 31, realizing the replacement of the lubricating grease in the annular groove 21 and ensuring a good lubricating effect on the damping ring 2.

[0031] Referring to Figure 1 and Figure 2, an installation ring 22 is integrally provided at the bottom end of the damping ring 2. The length of the installation ring 22 is arranged along the circumferential direction of the damping ring 2, and the height of the installation ring 22 is arranged along the vertical direction. An installation seat 4 is provided on the housing 1. An installation groove 41 for inserting and sliding the installation ring 22 is formed on the surface of the installation seat 4, and the installation ring 22 and the installation groove 41 are mutually adapted. A plurality of buffer springs 5 abutting against the bottom wall of the installation ring 22 are arranged in the installation groove 41. A plurality of guide rods 51 are arranged in the installation groove 41. The guide rods 51 are arranged along the depth direction of the installation groove 41. A guide groove 221 for inserting and sliding the guide rods 51 is formed on the bottom wall of the installation ring 22. The guide groove 221 and the guide rods 51 are mutually adapted. The buffer springs 5 are sleeved on the guide rods 51. When the damping ring 2 is subjected to the pressure of the body 11 and the installation ring 22 slides in the installation groove 41 under pressure, the guide rods 51 play a guiding role for the installation ring 22. The guide rods 51 slide in the guide groove 221. The buffer springs 5 abut against the bottom wall of the installation ring 22, and the buffer springs 5 deform, giving a certain displacement space to the damping ring 2. The buffer springs 5 play a certain buffering role for the damping ring 2, which is beneficial to extending the service life of the damping ring 2 and reducing the situation that the damping ring 2 is damaged due to excessive pressure from the body 11.

[0032] Refer to Figure 1 and Figure 2 , a plurality of connection holes 6 are penetrated and arranged on the bottom wall of the installation groove 41. A connection block 61 is threadedly connected in the connection holes 6. The guide rods 51 are fixedly arranged on the connection block 61. By rotating the connection block 61, the connection block 61 is separated from the connection holes 6. At this time, the guide rods 51 can be taken out of the installation groove 41, and then the buffer springs 5 can be taken out of the installation groove 41 through the connection holes 6, so that the buffer springs 5 can be replaced to ensure that the buffer springs 5 have a good abutting effect on the installation ring 22, which is convenient for maintaining the equipment. An abutting disc 611 is integrally provided on the connection block 61. An abutting groove 62 is formed on the inner wall of the connection hole 6.

[0033] Refer to Figure 1 , a plurality of installation bolts 7 are penetrated and arranged on the installation seat 4. The length direction of the installation bolts 7 is arranged horizontally. The installation bolts 7 are threadedly connected with the housing 1. The detachable connection between the installation seat 4 and the housing 1 is realized by using the installation bolts 7. Removing the installation seat 4 is convenient for installing, replacing and maintaining the damping ring 2.

[0034] Refer to Figure 1 and Figure 2, a bending portion 23 is provided between the mounting ring 22 and the damping ring 2. The bending portion 23 is integrally formed with the mounting ring 22 and the damping ring 2. The bending portion 23 improves the toughness between the mounting ring 22 and the damping ring 2, making the damping ring 2 not easily damaged when subjected to a large pressure, and further extending the service life of the damping ring 2.

[0035] The implementation principle of a safety type cone crusher in an embodiment of the present application is as follows: when the body 11 generates self-rotation, the damping ring 2 made of polyurethane material abuts against the surface of the body 11, increasing the contact area with the body 11. At the same time, the damping ring 2 has a relatively high hardness, significantly reducing the self-rotation speed of the body 11 and reducing the situation of dust entering the crusher. A circular groove 21 is provided on the surface of the damping ring 2. The length direction of the circular groove 21 is arranged along the circumferential direction of the damping ring 2. The circular groove 21 is used to store lubricating grease. When the body 11 rotates on the damping ring 2, the lubricating grease in the circular groove 21 can lubricate the surface of the damping ring 2, which is beneficial to extending the service life of the damping ring 2. Ensure that there is a certain pressure between the body 11 and the damping ring 2 after installation, forming sufficient friction to reduce the speed, thereby reducing the phenomenon of bushing burning on the body 11 and improving the safety of the crusher during use.

[0036] The above are all preferred embodiments of the present application. The protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
