A wear-resistant inner liner for easy-to-replace mining crushers

Abstract

This utility model discloses a wear-resistant inner liner plate for a mining crusher that is easy to replace. Applied in the mining field, it includes a crusher housing. An installation rod is slidably fitted onto the inner wall of the crusher housing. One end of the installation rod is bolted to an inner plate. A fixing block is bolted to the surface of the crusher housing, and the fixing block slidably fits onto the surface of the installation rod. A fixing pin is provided through the inner wall of the installation rod and the fixing block. This utility model achieves the purpose of convenient replacement by moving a pulling block to move a locking rod, which disengages from the fixing pin. The fixing pin is then removed, allowing the inner liner plate to be removed. This reduces workload and improves replacement efficiency. Furthermore, when ore impacts the outer plate, the outer plate causes the damper and second spring to contract, absorbing the impact energy and achieving a buffering effect, reducing the impact force on the equipment and increasing its service life.

Description

Technical Field

[0001] This utility model relates to the field of mining, and in particular to a wear-resistant inner liner plate for a mining crusher that is easy to replace. Background Technology

[0002] A search of Chinese patents revealed publication number CN218962832U, concerning ball mill liners, which falls under the technical field of ball mill technology and addresses the current problem of short lifespan for ball mill liners. The design includes a cylinder with a lower fixing hole and a bottom plate. The bottom plate has a protrusion and an upper fixing hole, both containing fixing screws. The protrusion has upper and lower threaded holes, each containing a bolt. Replacement is achieved through these bolts and the lower fixing hole, thus extending the lifespan of the ball mill liner.

[0003] Existing inner liner plates are inconvenient to replace. Generally, the inner liner plates are fixed to the crusher shell with bolts. When replacing them, tools are required for disassembly and assembly, which is cumbersome, increases workload, reduces replacement efficiency, and lacks a buffer function. During use, the ore constantly impacts the inner liner plates, which affects the stability of the equipment structure and reduces the service life of the equipment over a long period of time. In order to solve the above problems, we propose a wear-resistant inner liner plate for mining crushers that is easy to replace. Utility Model Content

[0004] The purpose of this invention is to provide a wear-resistant inner liner for a mining crusher that is easy to replace. Its advantages are that it is easy to replace and has a cushioning function.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a wear-resistant inner liner plate for a mining crusher that is easy to replace, comprising a crusher housing, an installation rod slidably sleeved on the inner wall of the crusher housing, an inner plate bolted to one end of the installation rod, a fixing block bolted to the surface of the crusher housing, and the fixing block slidably sleeved with the surface of the installation rod, a fixing pin penetrating through the inner walls of the installation rod and the fixing block, a snap-fit ​​rod slidably sleeved on the inner wall of the fixing block, and the snap-fit ​​rod slidably sleeved with the inner wall of the fixing pin, a limit plate fixedly sleeved on the surface of the snap-fit ​​rod, and a first spring provided between the limit plate and the inner wall of the fixing block.

[0006] By adopting the above technical solution, the locking rod is moved by moving the pull block, and the locking rod is disengaged from the fixing pin. Then the fixing pin is removed, and the inner liner is removed. This method can achieve the purpose of making replacement inconvenient, reduce the workload, and improve the efficiency of replacement.

[0007] The present invention is further configured such that: a damper is fixedly sleeved on the inner wall of the inner plate, and the damper is slidably sleeved on the inner wall of the crusher housing; an outer plate is bolted to one end of the damper; a second spring is sleeved on the surface of the damper, and the second spring is located between the outer plate and the inner plate.

[0008] By adopting the above technical solution, when the ore hits the outer plate, the outer plate drives the damper and the second spring to contract, thereby absorbing the impact energy, achieving the purpose of buffering, reducing the impact force on the equipment, and improving its service life.

[0009] The present invention is further configured such that: the outer plate includes a base plate, a buffer plate and a wear-resistant plate, and the buffer plate is located between the base plate and the wear-resistant plate.

[0010] By adopting the above technical solution, by setting a base plate, a buffer plate, and a wear-resistant plate, the buffer plate improves the buffering effect, and the wear-resistant plate improves the wear resistance of the outer plate and extends its service life.

[0011] The present invention is further configured such that a pull block is bolted to one end of the locking rod.

[0012] By adopting the above technical solution, the locking rod can be easily moved by setting a pull block.

[0013] The present invention is further configured such that the surface of the outer plate is provided with anti-wear texture.

[0014] By adopting the above technical solution, the wear resistance is improved by setting anti-wear texture.

[0015] The present invention is further configured such that the buffer plate is made of rubber.

[0016] By adopting the above technical solution and setting the material of the buffer plate to rubber, the buffering effect is good.

[0017] The present invention is further configured such that the wear-resistant plate is made of high manganese steel.

[0018] By adopting the above technical solution, the wear-resistant plate is made of high manganese steel, which has high strength and high wear resistance and can withstand large impact loads.

[0019] The present invention is further configured such that one end of the snap-fit ​​rod is arc-shaped.

[0020] By adopting the above technical solution, one end of the snap-fit ​​rod is made into an arc shape, which facilitates insertion into the fixing pin.

[0021] In summary, this utility model has the following beneficial effects:

[0022] 1. This utility model achieves the purpose of inconvenient replacement by moving the pull block to move the locking rod, and the movement of the locking rod causes the locking rod to disengage from the fixing pin. Then the fixing pin is removed and the inner liner is removed. This reduces the workload and improves the efficiency of replacement.

[0023] 2. This utility model achieves the purpose of buffering by causing the outer plate to contract when the ore hits the outer plate, thereby reducing the impact force on the equipment and improving its service life. Attached Figure Description

[0040] Brief description of the usage process: Move the pull block 15. The movement of the pull block 15 drives the locking rod 6 to move. The movement of the locking rod 6 disengages the locking rod 6 from the fixing pin 5. Then, remove the fixing pin 5 and replace the inner liner plate. Insert the mounting rod 2 on the new inner liner plate into the fixing block 4 from inside the crusher. Then, insert the fixing pin 5 and release the pull block 15. The locking rod 6 passes through the fixing pin 5 under the action of the first spring 8, fixing the fixing pin 5 and completing the replacement, thus achieving the purpose of easy replacement. When the ore hits the outer plate 10, the outer plate 10 drives the damper 9 and the second spring 11 to contract, absorbing the impact energy and achieving the purpose of buffering.
