Technical Field
[0001] This utility model relates to the technical field of crushers with a quick-change structure for wear-resistant liners, and particularly to a crusher with a quick-change structure for wear-resistant liners. Background Technology
[0002] In industries such as mining, construction, and metallurgy, crushers are key equipment for material crushing and processing. Their feed inlets, crushing chambers, and other parts are in constant contact with hard materials and are therefore highly susceptible to impact and wear. As a result, wear-resistant liners are usually installed to protect the equipment body and extend its service life.
[0003] Existing crushers with quick-change wear-resistant liners may have issues with the inability to quickly position and disassemble the liners at the feed inlet. In actual use, excessive positioning time will extend the overall operation time for liner replacement, leading to increased downtime maintenance cycles for the crusher. Furthermore, the disassembly and assembly process is cumbersome, requiring more manual operation, which may increase the probability of errors due to the complexity of the operation steps. Therefore, we propose a crusher with a quick-change wear-resistant liner structure. Utility Model Content
[0004] The purpose of this utility model is to provide a crusher with a quick-replacement structure for wear-resistant liners, so as to solve the problem mentioned in the background art that the liner at the feed inlet may not be able to be quickly positioned and disassembled. In actual use, the positioning time is too long, which will prolong the overall operation time of liner replacement, resulting in an increase in the downtime maintenance cycle of the crusher. The disassembly and assembly process is cumbersome, requiring more manual operation, and the complexity of the operation steps may increase the probability of error.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a crusher with a quick-change structure for wear-resistant liners, comprising a crusher body, a crushing device disposed inside the crusher body, a feed inlet disposed at the top of the crusher body, and a quick-change assembly disposed outside the feed inlet. The quick-change assembly includes a liner body, a wing bolt, a sealing ring, and a thin wear-resistant rubber plate. The liner body is connected to a limit rod via a connecting block. A connecting plate is fixedly connected to the top side of the liner body. Threaded grooves are provided on the top of the connecting plate and the top of the feed inlet.
[0006] As a preferred embodiment, the feed inlet has limit holes on both the top front and the top back. There are two sets of connecting blocks and limit rods. The two sets of connecting blocks are fixedly connected to the top front and the top back of the liner body, respectively, and the two sets of limit rods are fixedly connected to the bottom of the two sets of connecting blocks.
[0007] As a preferred embodiment, the two sets of limiting rods are slidably connected inside the two limiting holes, the top of the connecting plate is provided with a sealing groove, the sealing groove is located above the threaded groove, and the sealing ring is set on the outer wall of the wing bolt.
[0008] As a preferred embodiment, the sealing ring is adapted to the sealing groove, the wing bolt is threaded into the inside of the thread groove, the thin wear-resistant rubber plate is fixedly connected to the outer wall of the liner body, and the outer wall of the thin wear-resistant rubber plate is in contact with the inner wall of the feed inlet.
[0009] As a preferred embodiment, the liner body is provided with a disassembly assembly, which includes screws. The liner body is symmetrically divided into two groups. One group of the liner body has three sets of inserts fixedly connected to its inner wall, and the other group of the liner body has three sets of insertion holes on its inner wall.
[0010] As a preferred embodiment, the three sets of inserts are inserted into the interior of the three sets of sockets. Threaded holes are provided inside the three sets of inserts, the three sets of sockets, and the interior of the liner body. The screw is threaded into the interior of the threaded holes.
[0011] The technical effects and advantages of this utility model are as follows: With the quick-change components, the limiting rod and limiting hole slide together to provide precise guidance for the liner body and achieve rapid positioning. The threaded groove of the connecting plate and the feed port are matched with the wing bolts, allowing workers to fix and disassemble by hand without tools, thus speeding up the replacement process. The sealing ring and sealing groove ensure a seal without increasing the installation difficulty. In summary, the cooperation of each component enables the quick positioning and disassembly of the liner body, shortening the replacement time, reducing the difficulty, and improving maintenance efficiency. With its modular design and disassembly components, the liner body is symmetrically divided into two groups. It is modularly disassembled by inserting three sets of blocks and holes. When the liner body is partially worn, it is not necessary to replace the whole body; only the worn group needs to be replaced. This reduces material waste. After the blocks and holes are quickly positioned and connected, they can be securely spliced by passing screws through the threaded holes. The installation is efficient. When replacing, simply unscrew the corresponding screws and pull out the blocks. The operation is simple, greatly shortening the replacement time and improving efficiency. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] Please see the appendix Figure 1 - Appendix Figure 5 A crusher with a quick-change structure for wear-resistant liners includes a crusher body 1, a crushing device 2 inside the crusher body 1, a feed inlet 3 on the top of the crusher body 1, and a quick-change assembly 4 outside the feed inlet 3. The quick-change assembly 4 includes a liner body 403, a wing bolt 407, a sealing ring 408, and a thin wear-resistant rubber plate 410. The liner body 403 is connected to a limit rod 405 via a connecting block 404. A connecting plate 406 is fixedly connected to the top side of the liner body 403. Threaded grooves 402 are provided on the top of the connecting plate 406 and the top of the feed inlet 3. Limit holes 401 are provided on the top front and the top back of the feed inlet 3. Two sets of connecting blocks 404 and limit rods 405 are provided. The two sets of connecting blocks 404 are fixedly connected to the top front and the top back of the liner body 403, respectively, and the two sets of limit rods 405 are fixedly connected to the bottom of the two sets of connecting blocks 404.
[0016] The crushing device 2 is the core working component of the crusher body 1, responsible for crushing the incoming material. A motor that drives the crushing device 2 is installed on the side of the crusher body 1. The feed inlet 3 is the channel for material to enter the crusher body 1 and is the direct installation position of the liner body 403. Since the material will scour the inner wall when it enters at high speed, it is easy to cause wear. Therefore, the liner body 403 is needed for protection. At the same time, the limiting hole 401 and the threaded groove 402 opened on the top of the feed inlet 3 are the connection basis for the quick replacement component 4.
[0017] Two sets of limiting rods 405 are slidably connected to the inside of two limiting holes 401 respectively. A sealing groove 409 is opened on the top of the connecting plate 406. The sealing groove 409 is located above the threaded groove 402. The sealing ring 408 is set on the outer wall of the wing bolt 407. The sealing ring 408 is adapted to the sealing groove 409. The wing bolt 407 is threadedly connected to the inside of the threaded groove 402. The thin wear-resistant rubber plate 410 is fixedly connected to the outer wall of the liner body 403. The outer wall of the thin wear-resistant rubber plate 410 is in contact with the inner wall of the feed port 3.
[0018] A thin, wear-resistant rubber sheet 410 is fixed to the outer wall of the liner body 403 on the side that contacts the inner wall of the feed inlet 3. The sheet is made of wear-resistant rubber and can buffer the hard contact between the liner body 403 and the inner wall of the feed inlet 3, reducing vibration and noise during equipment operation. It can also fill the tiny gap between the liner body 403 and the feed inlet 3, further enhancing the sealing performance and preventing material from seeping in. Utilizing the elasticity of the rubber, the liner body 403 is installed more closely, avoiding excessive local stress caused by gaps.
[0019] Specifically, through the quick-change component 4, the limiting rod 405 and the limiting hole 401 slide to provide guidance for the liner body 403 and achieve positioning. The connecting plate 406 and the threaded groove 402 of the feed port 3 are matched with the wing bolt 407, allowing the staff to complete the fixing and disassembly by hand, eliminating the need for tools and speeding up the replacement. The sealing ring 408 and the sealing groove 409 ensure sealing without increasing the installation difficulty. In summary, the cooperation of each component realizes the positioning and disassembly of the liner body 403, shortens the replacement time, reduces the difficulty, and improves maintenance efficiency.
[0020] Please see the appendix Figure 1 Appendix Figure 3 and appendix Figure 5 The liner body 403 is provided with a disassembly assembly 5 inside. The disassembly assembly 5 includes screws 504. The liner body 403 is symmetrically divided into two groups. Three sets of insert blocks 501 are fixedly connected to the inner wall of one group of liner bodies 403. Three sets of insertion holes 503 are opened on the inner wall of the other group of liner bodies 403. The three sets of insert blocks 501 are inserted into the three sets of insertion holes 503. Threaded holes 502 are opened in the interior of the three sets of insert blocks 501, the interior of the three sets of insertion holes 503, and the interior of the liner body 403. Screws 504 are threadedly connected to the interior of the threaded holes 502.
[0021] The threaded hole 502 penetrates the interior of the insert block 501, the insert hole 503, and the liner body 403, forming a continuous threaded channel. This provides a screw path for the screw 504, allowing the two sets of liner bodies 403 to be connected as a whole by the screw 504.
[0022] Specifically, through the set disassembly component 5, the liner body 403 is symmetrically divided into two groups. The three groups of insert blocks 501 are inserted into the sockets 503 to achieve modular disassembly. When the liner body 403 is partially worn, it does not need to be replaced as a whole. Only the worn group is replaced, which reduces material waste. After the insert block 501 is positioned and connected with the socket 503, the screw 504 is passed through the threaded hole 502 to achieve a firm splicing. The installation is efficient. When replacing, simply unscrew the corresponding screw 504 and pull out the insert block 501. The operation reduces replacement time and improves efficiency.
[0023] Working principle of this utility model: This utility model is a crusher with a quick-replacement structure for wear-resistant liners. First, when installing the liner body 403, the operator aligns and inserts the insert blocks 501 of the two sets of liner bodies 403 in the disassembly assembly 5 with the insert holes 503, aligning the threaded holes 502. Then, the screws 504 are screwed into the threaded holes 502 to complete the splicing and fixing of the two sets of liner bodies 403. Subsequently, the operator picks up the spliced liner body 403, aligns the limiting rods 405 on its front and back with the limiting holes 401 of the feed inlet 3, and slides them in to achieve positioning. Then, the threaded groove 4 on the top of the connecting plate 406 is aligned with the limiting holes 401 of the feed inlet 3. Align the threaded groove 402 at the top of the feed inlet 3 with the 02, and manually screw the wing bolt 407 with the sealing ring 408 into the threaded groove 402, so that the sealing ring 408 is embedded in the sealing groove 409, thus completing the fixed installation of the liner body 403. At this time, the thin wear-resistant rubber plate 410 is in contact with the inner wall of the feed inlet 3. When it is necessary to replace the liner body 403, the worker first unscrews the wing bolt 407 by hand, and pulls out the liner body 403 along the limiting hole 401. If there is only local wear, unscrew the screw 504 of the corresponding liner body 403, pull out the insert 501, replace the worn group, reassemble, and then fix it according to the above installation steps.
[0024] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
