Description

Technical Field

[0001] This utility model relates to the field of grinding or crushing technology, and in particular to a structure for easy disassembly and assembly of a mining crusher liner. Background Technology

[0002] In the field of mining and ore processing, mining crushers are the core equipment for primary crushing of ore, and liners, as key components that come into direct contact with the ore inside the mining crusher, are like the "armor" of the crusher, playing an irreplaceable role in the entire crushing process.

[0003] Currently, most mining crushers on the market use liners with a flat surface design. However, in actual use, due to the irregular shape and large hardness differences of the ore, the flat surface of the liner cannot effectively restrict the sliding trajectory of the ore when it moves in the crushing chamber. After being subjected to crushing force, the ore is prone to sliding disorderly on the liner surface, resulting in dispersed crushing force and difficulty in concentrating the force to crush the ore efficiently. This not only prolongs the crushing time and reduces the crushing efficiency, but also increases the energy consumption of the crusher. Since the crushing force cannot be precisely applied to the key parts of the ore, the crusher needs to repeatedly crush the same batch of ore to achieve the expected particle size requirements, which greatly reduces the efficiency of the entire production process. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a convenient disassembly and assembly structure for mining crusher liners. This structure can solve the problem that the flat surface of the liner cannot effectively restrict the sliding trajectory of the ore. After the ore is subjected to crushing force, it is easy for the ore to slide randomly on the liner surface, resulting in the dispersion of crushing force and difficulty in concentrating the crushing force on the ore for efficient crushing. This not only prolongs the crushing time and reduces the crushing efficiency, but also increases the energy consumption of the crusher. Since the crushing force cannot be accurately applied to the key parts of the ore, the crusher needs to repeatedly crush the same batch of ore to achieve the expected particle size requirements, which greatly reduces the efficiency of the entire production process.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a convenient disassembly and assembly structure for mining crusher liners, comprising an installation frame, two installation plates, and four liners, wherein each of the four liners is provided with multiple protective strip components; The protective strip assembly includes a protective component and a second T-shaped slider. When the protective component is a corrugated protective strip, the second T-shaped slider is fixedly installed on the outer wall of the protective component. The lower outer wall of the protective component is threaded with a second fixing bolt. Multiple second T-shaped slider grooves are opened on the outer walls of the four liner plates. Among them, the inner walls of multiple second T-shaped slider grooves are equipped with magnetic seats, the lower outer walls of the four liners are provided with multiple second fixing bolt grooves, the outer wall of the second T-shaped slider away from the protective component is equipped with a magnetic positioning block, and multiple protective strip assemblies are installed on the outer walls of the liners and used in conjunction.

[0006] Preferably, the outer wall of the second T-shaped slider is slidably connected to the interior of the corresponding second T-shaped slider groove.

[0007] Preferably, the magnetic positioning block is used in conjunction with the magnetic base.

[0008] Preferably, the end of the second fixing bolt near the second fixing bolt groove extends outward to the outside of the protective member and is respectively connected to the internal thread of the corresponding second fixing bolt groove.

[0009] Preferably, the mounting frame is U-shaped, with two mounting plates fixedly installed on the left and right outer walls of the mounting frame, and a first T-shaped slider groove provided on the left and right inner walls of the mounting frame.

[0010] Preferably, the left and right outer walls of the four liner plates are all fixedly installed with first T-shaped sliders, and the left and right outer walls of the upper end of the mounting frame are all threaded with first fixing bolts.

[0011] Preferably, the four liner plates are slidably connected to the inner grooves of the corresponding first T-shaped sliders on the left and right outer walls, allowing the liner plates to be quickly installed inside the mounting frame.

[0012] Preferably, the outer walls of the two first T-shaped sliders on the upper liner are provided with first fixing bolt grooves, and the ends of the two first fixing bolts near the first fixing bolt grooves are threaded into the interior of the first T-shaped slider grooves and respectively connected to the internal threads of the corresponding first fixing bolt grooves.

[0013] Preferably, when all of the protective components are serrated protective strips, the serrated protective strips are installed on the outer wall of the corresponding liner plate and used in conjunction with each other via a second T-shaped slider and a second fixing bolt.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. This easy-to-assemble and disassemble mining crusher liner structure allows for two types of protective strips in the protective strip assembly: corrugated or serrated. When using corrugated protective strips, the continuous alternating peaks and troughs create a dual "blocking-guiding" effect. As the ore moves within the crushing chamber, the peaks effectively restrict the disorderly sliding of the ore, guiding it along a preset trajectory. This ensures that the crushing force is precisely applied to the part of the ore to be crushed, preventing the crushing force from being dispersed due to ore slippage. When using serrated protective strips, the serrated protrusions can be directly embedded into the ore surface, enhancing the gripping force on the ore. This is especially effective for ores with high hardness and prone to slippage, preventing them from shifting during the crushing process and ensuring that the impact and compression of the crushing components, such as the crusher rotor and jaw plates, on the ore is concentrated and efficient.

[0017] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] In the description of this utility model, terms such as greater than, less than, and exceeding are understood to exclude the stated number, while terms such as above, below, and within are understood to include the stated number. The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0020] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0021] Example 1: Reference Figure 1-4 A typical example of conventional ore crushing basic construction (corrugated protective strip + magnetic positioning). Suitable for processing conventional ores with low hardness such as limestone and clay, it provides basic protection through corrugated protective strips and magnetic positioning. The protective strips are made of ordinary wear-resistant rubber with a corrugated structure, which uses the corrugated surface to disperse the impact force of the ore. The second T-shaped slider is slidably connected to the second T-shaped slider groove of the liner plate. The magnetic positioning block and the magnetic seat cooperate to achieve quick positioning, and then it is tightened with the second fixing bolt. In daily crushing operations, the corrugated protective strips effectively buffer the impact of the ore, and the magnetic positioning ensures accurate installation. Disassembly can be achieved by unscrewing the bolts. It is suitable for daily maintenance in small and medium-sized mines.

[0022] Example 2: Reference Figure 5 Example of wear-resistant design for high-hardness ores (serrated protective strip + high-strength bolts) For applications involving the handling of high-hardness ores such as quartz and iron ore, a serrated protective strip and high-strength bolts are used to enhance wear resistance. The protective strip is replaced with a serrated protective strip cast from high-manganese steel. The serrated edge can break the sharp edges of the ore, reducing direct wear. The second fixing bolt is replaced with a high-strength alloy bolt, and the second T-shaped slider is thickened. Under the frequent impact of high-hardness ores, the serrated protective strip actively breaks the ore, reducing liner wear. The high-strength bolts ensure a stable connection and extend the service life of the liner. It is suitable for heavy-duty crushing operations in large mines.

[0023] Furthermore, when using this device, firstly, the mounting frame 1 is fixed in the designated position inside the crusher using the mounting plate 2. Then, the four liners 4 are slid into the first T-shaped slider grooves 6 on the left and right inner walls of the mounting frame 1 via the first T-shaped sliders 5 on the left and right outer walls, achieving the initial installation of the liners 4. Finally, the first fixing bolts 3 at the upper end of the mounting frame 1 are tightened, so that the bolt ends are screwed into the first fixing bolt grooves 11 of the upper liner 4, completing the fixing of the liner 4 to the mounting frame 1. Then, when installing the corrugated protective strip... The protective strip 7 is slid into the second T-shaped slider groove 10 of the liner plate 4 via the second T-shaped slider 9 on the outer wall. At this time, the magnetic positioning block 12 on the second T-shaped slider 9 is magnetically attracted to the magnetic seat 13 in the groove, thus achieving the pre-fixation of the protective strip 7. Then, the second fixing bolt 8 at the lower end of the protective strip 7 is tightened so that the bolt end is screwed into the second fixing bolt hole 14 of the liner plate 4, completing the final fixation of the protective strip 7. Then, when using the serrated protective strip 15, the installation principle is the same as that of the corrugated protective strip. The second T-shaped slider 9 and the second T-shaped slider 9 are connected to the liner plate 4 to fix the protective strip 7. Positioning is achieved through the cooperation of the second T-shaped slider groove 10, and then fixed by the connection of the second fixing bolt 8 and the second fixing bolt hole 14. When the crusher is working, the ore comes into direct contact with the protective strip 7 (corrugated or serrated) on the surface of the liner 4. The protective strip 7, with its special shape, disperses the impact force of the ore, reducing wear on the liner 4. Simultaneously, the firm connection between the protective strip 7 and the liner 4 (the second fixing bolt 8 and magnetic attraction) ensures that it will not fall off under the impact of the ore. Meanwhile, the liner 4 is connected to the mounting frame via the first T-shaped slider 5. The first T-shaped slider groove 6 of 1 fits tightly, and with the locking of the first fixing bolt 3, it ensures that there will be no displacement during the violent vibration of the crushing operation, ensuring the stability of the overall structure. Then, when disassembling the protective strip 7, simply loosen the second fixing bolt 8, and the protective strip 7 can be slid out along the second T-shaped slider groove 10. The separation of the magnetic positioning block 12 and the magnetic seat 13 is convenient and labor-saving. When replacing the liner 4, loosen the first fixing bolt 3, and the liner 4 can be slid out along the first T-shaped slider groove 6. No complicated tools are required, and quick disassembly and assembly are achieved.

[0024] The protective strip 7 in the protective strip assembly can adopt two structures: corrugated or sawtooth protective strip 15. When the corrugated protective strip is used, its continuous alternating crests and troughs can form a dual function of "blocking and guiding". When the ore moves in the crushing chamber, the crests can effectively limit the disorderly sliding of the ore and guide the ore to move along the preset trajectory, so that the crushing force is accurately applied to the part of the ore to be crushed and the crushing force is not dispersed due to the sliding of the ore. When the sawtooth protective strip 15 is used, the sawtooth protrusions can be directly embedded into the surface of the ore to enhance the gripping force on the ore. Especially for ores with high hardness and easy slippage, it can effectively prevent them from shifting during the crushing process and ensure that the impact and squeezing action of the crushing components (such as the crusher rotor and jaw plates) on the ore is concentrated and efficient.

[0025] Structural Description: Mounting Frame 1: The frame has an overall "U" shape and serves as the basic support component for the entire liner structure, providing a mounting carrier for the liner 4. The left and right inner walls are symmetrically provided with first T-shaped slider grooves 6 for sliding installation of the liner 4. Mounting plates 2 are fixedly installed on the upper left and right outer walls, which can fix the entire device inside the crusher. The upper left and right outer walls are also threaded with first fixing bolts 3 for locking the installation position of the liner 4.

[0026] Mounting plate 2: There are two mounting plates 2, which are fixed to the left and right outer walls of the mounting frame 1 respectively. Their main function is to fix the mounting frame 1 to the designated position of the crusher by bolts and other connecting parts, so as to ensure that the entire liner structure remains stable when the crusher is working.

[0027] First fixing bolt 3: Installed on the left and right outer walls of the upper end of the mounting frame 1, its screw part can be threaded into the inside of the first T-shaped slider groove 6. When the liner 4 slides into the mounting frame 1 through the first T-shaped slider 5, the first fixing bolt 3 can be screwed into the first fixing bolt groove 11 of the upper liner 4 to fix the liner 4 and prevent it from sliding during operation.

[0028] Liner 4: There are four liner plates 4 in total. They are the core components that come into direct contact with the ore. First T-shaped sliders 5 are fixedly installed on the left and right outer walls. The sliders are slidably installed by cooperating with the first T-shaped slider grooves 6 of the mounting frame 1. Multiple second T-shaped slider grooves 10 are opened on the outer wall for installing the protective strip assembly. Multiple second fixing bolt holes 14 are opened on the lower outer wall for fixing the protective strip 7 with the second fixing bolts 8.

[0029] The first T-shaped slider 5 is fixedly installed on the left and right outer walls of the liner plate 4 and matches the first T-shaped slider groove 6 of the mounting frame 1. Through the sliding cooperation between the slider and the groove, the liner plate 4 can be quickly embedded into the mounting frame 1 to achieve convenient installation. The outer wall of the first T-shaped slider 5 of the upper liner plate 4 is also provided with a first fixing bolt groove 11, which is used to lock the position with the first fixing bolt 3.

[0030] The first T-shaped slider groove 6 is formed on the left and right inner walls of the mounting frame 1 to provide a sliding track for the first T-shaped slider 5. The size of the groove matches the first T-shaped slider 5, which not only ensures smooth sliding of the slider, but also restricts the vertical displacement of the liner 4 to ensure installation stability.

[0031] Protective strip 7: As a protective structure that directly contacts the ore, it has two forms: corrugated protective strip and serrated protective strip 15. It is installed on the outer wall of the liner plate 4 through the second T-shaped slider 9 and the second fixing bolt 8. It can enhance the wear resistance of the liner plate surface, and at the same time, the special shape can change the movement trajectory of the ore and improve the crushing efficiency.

[0032] The second fixing bolt 8 is threaded onto the lower outer wall of the protective strip 7. Its threaded portion can extend to the outside of the protective strip 7 and is threaded into the second fixing bolt hole 14 of the liner plate 4. It is used to firmly fix the protective strip 7 onto the liner plate 4 to prevent it from falling off under the impact of ore.

[0033] The second T-shaped slider 9 is fixedly installed on the outer wall of the protective strip 7 and matches the second T-shaped slider groove 10 of the liner plate 4. Through the sliding cooperation between the slider and the groove, the protective strip 7 can be quickly positioned and installed on the liner plate 4, while limiting the lateral displacement of the protective strip 7.

[0034] The second T-shaped slider groove 10 is formed on the outer wall of the liner plate 4 to provide a sliding track for the second T-shaped slider 9. A magnetic seat 13 is installed on the inner wall of the groove, which can cooperate with the magnetic positioning block 12 of the protective strip 7 to achieve the pre-fixation of the protective strip 7.

[0035] First fixing bolt groove 11: It is opened on the outer wall of the first T-shaped slider 5 of the upper liner plate 4 and corresponds to the position of the first fixing bolt 3. When the first fixing bolt 3 is screwed into the groove, the liner plate 4 and the mounting frame 1 can be locked to prevent relative sliding.

[0036] Magnetic positioning block 12: Installed on the outer wall of the second T-shaped slider 9 away from the protective strip 7, it magnetically attracts the magnetic seat 13 in the slide groove 10 of the second T-shaped slider, providing pre-fixing force during the installation of the protective strip 7, which facilitates the subsequent installation of the second fixing bolt 8.

[0037] Magnetic base 13: Installed on the inner wall of the second T-shaped slider groove 10, and used in conjunction with the magnetic positioning block 12, to temporarily fix the protective strip 7 to the liner 4 through magnetic attraction, so as to prevent the protective strip 7 from slipping off during installation.

[0038] The second fixing bolt hole 14 is located on the lower outer wall of the liner plate 4, corresponding to the position of the second fixing bolt 8. The protective strip 7 is finally fixed to the liner plate 4 through the threaded connection with the second fixing bolt 8, ensuring a firm connection.

[0039] Serrated Protective Strip 15: Another form of protective strip 7, which is installed on the outer wall of liner 4 by the second T-shaped slider 9 and the second fixing bolt 8. The serrated structure can enhance the crushing effect on ore and is suitable for crushing scenarios of ore with different hardness.

[0040] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
