Description

Technical Field

[0001] This utility model relates to the technical field of jaw crusher liners, specifically to a wear-resistant structure for jaw crusher liners. Background Technology

[0002] Jaw crusher liners are wear-resistant and vulnerable components installed on the working surfaces of the fixed and movable jaws of the crusher. They are used to crush materials by directly contacting them and bearing the squeezing and impact. They are mostly made of wear-resistant materials such as high manganese steel and wear-resistant alloy steel. The structural design needs to be adapted to the movement trajectory of the jaw plate and the crushing characteristics of the material. They can not only protect the jaw body from wear, but also improve crushing efficiency and reduce energy consumption by optimizing the tooth shape, thickness and installation method.

[0003] However, the wear-resistant structure of existing jaw crusher liners mostly adopts a right-angle convex tooth design to achieve material crushing. However, traditional flat or simple toothed liners have obvious defects: In actual working conditions, due to the compound movement of the moving jaw, the material and the liner will inevitably slide relative to each other. The flat liner has a smooth contact surface, and the simple convex tooth has insufficient meshing depth. As a result, the extrusion force pushes the material to slide along the liner surface, forming a mode of extrusion as the main force and sliding friction as the auxiliary force. Friction not only consumes energy, but also aggravates the wear of the liner. On the other hand, existing liners are mostly integral structures. Disassembly and maintenance require disassembly and assembly of the entire liner, which is cumbersome and not very convenient to use. Utility Model Content

[0004] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0005] In view of the problems existing in the above and / or existing jaw crusher liners, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a wear-resistant structure for jaw crusher liners.

[0007] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0008] A wear-resistant structure for a jaw crusher liner includes a liner body. A snap-fit ​​groove is formed on the front outer wall of the liner body, and crushing components for crushing are snapped into the inner walls of multiple snap-fit ​​grooves. The crushing components include snap-fit ​​plates, guide strips, corrugated ribs, and crushing protrusions. A slot is formed on the rear outer wall of the liner body, and a limiting component for limiting and fixing multiple crushing components is installed on the inner wall of the slot. The limiting component includes a connecting block, bolts, and a limiting baffle.

[0009] In a preferred embodiment of the wear-resistant structure of the jaw crusher liner described in this utility model, the snap-fit ​​plate is slidably snapped into the snap-fit ​​groove, and both the snap-fit ​​plate and the snap-fit ​​groove are mutually compatible cross-shaped.

[0010] As a preferred embodiment of the wear-resistant structure of the jaw crusher liner of this utility model, the corrugated ribs are integrally formed on the front outer wall of the snap-fit ​​plate.

[0011] As a preferred embodiment of the wear-resistant structure of the jaw crusher liner of this utility model, a plurality of crushing protrusions are integrally formed on the outer wall in front of the corrugated rib, and the heights of the plurality of crushing protrusions are distributed in a gradient.

[0012] In a preferred embodiment of the wear-resistant structure of the jaw crusher liner described in this utility model, the connecting block is located inside the slot, and multiple connecting blocks are fixed to the inner wall of the slot by bolts.

[0013] As a preferred embodiment of the wear-resistant structure of the jaw crusher liner of this utility model, a limiting baffle is integrally formed on the front outer wall of the plurality of connecting blocks, and the limiting baffle is located on the top of the plurality of snap-fit ​​plates.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: In practical applications, the device features multiple wavy convex strip structures on the working surface of the liner body. These wavy convex strip structures, through their curved peaks and groove contours, can create a better biting and locking effect on multiple edges of the material, significantly increasing the meshing depth and friction, constraining material sliding, and converting all the motion energy of the moving jaw into squeezing and shearing forces on the material. This reduces energy waste due to frictional loss and decreases wear caused by sliding friction. Secondly, multiple gradient-arranged crushing protrusions can further form a vertical biting and positioning of the material, further suppressing additional wear caused by excessive material sliding and extending the service life of its wear-resistant structure. Thirdly, the modular disassembly design allows for easy replacement of damaged or severely worn parts by simply removing bolts and taking out the limiting baffle. This eliminates the need for complete disassembly of the liner body, avoiding the high costs associated with overall replacement, simplifying the maintenance process, shortening downtime, and significantly improving the convenience of equipment use and maintenance.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0026] This utility model provides a wear-resistant structure for a jaw crusher liner, including a liner body 100. The front outer wall of the liner body 100 has a snap-fit ​​groove 102. Multiple snap-fit ​​grooves 102 have crushing parts snapped into their inner walls. The crushing parts include a snap-fit ​​plate 200, a guide strip 210, a corrugated rib 220, and a crushing protrusion 230. The rear outer wall of the liner body 100 has a slot 101. The inner wall of the slot 101 is equipped with a limiting component for limiting and fixing multiple crushing parts. The limiting component includes a connecting block 110, a bolt 120, and a limiting baffle 130.

[0027] Specifically, the snap-fit ​​plate 200 is slidably snapped into the snap-fit ​​groove 102. Both the snap-fit ​​plate 200 and the snap-fit ​​groove 102 are cross-shaped and compatible, which makes it easier for the snap-fit ​​plate 200 of the broken part to be better snapped and limited inside the snap-fit ​​groove 102.

[0028] Specifically, the corrugated strip 220 is integrally formed on the front outer wall of the snap-fit ​​plate 200.

[0029] In some embodiments: the liner body 100 is made of manganese steel, and the crushing parts are made of YG15 / YG20 cemented carbide.

[0030] Specifically, multiple crushing protrusions 230 are integrally formed on the outer wall in front of the corrugated ribs 220, and the heights of the multiple crushing protrusions 230 are distributed in a gradient, which facilitates better crushing of materials.

[0031] Specifically, the connecting block 110 is located inside the slot 101. More specifically, the front outer wall of the multiple connecting blocks 110 is integrally formed with a limiting baffle 130. The limiting baffle 130 is located on the top of the multiple snap-fit ​​plates 200, which facilitates the limiting baffle 130 to limit and fix the top of the multiple broken parts.

[0032] In this embodiment, in practical application, the device features multiple corrugated ribs 220 on the working surface of the liner body 100. These corrugated ribs 200, through their curved peaks and grooves, create a better locking effect on the multiple edges of the material, significantly increasing the engagement depth and friction, constraining material sliding, and converting all the motion energy of the moving jaw into squeezing and shearing forces on the material. This reduces energy waste due to frictional loss and minimizes wear caused by sliding friction. Secondly, multiple gradient-arranged crushing protrusions 230 further form a vertical engagement and positioning of the material, further suppressing additional wear caused by excessive material sliding and extending the service life of its wear-resistant structure. Thirdly, the modular design allows for easy replacement of damaged or severely worn parts by simply removing the bolts 120 and taking out the limiting baffle 130. This eliminates the need for complete disassembly of the liner body, avoiding the high costs associated with overall replacement, simplifying maintenance procedures, shortening downtime, and significantly improving the convenience of equipment use and maintenance.

[0033] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
