DETAILED DESCRIPTION

[0034] In order to more clearly illustrate the technical solutions of the embodiments of the present application or the prior art, the specific implementation manners of the present application will be described below with reference to the drawings. Obviously, the drawings described below are only some embodiments of the present application, and for those skilled in the art, other drawings can be obtained from these drawings without creative labor, and other embodiments can also be obtained.

[0035] In order to make the drawings simple, only the parts related to the present application are shown in the drawings, and they do not represent the actual structure of the product. In addition, in order to make the drawings simple and easy to understand, in some drawings, only one of the parts with the same structure or function is shown, or only one of them is marked. In this paper, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0036] ​In this article, it is necessary to explain that, unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connecting" should be broadly understood, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, and it can be connected inside two elements. For those skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0037] In addition, in the description of the present application, the terms "first", "second" and the like are only used for differentiation and description, and cannot be understood as indicating or implying relative importance.

[0038] Reference Figures 1-6 For the first embodiment of the utility model, a side plate of a grading crusher is provided, comprising: a side plate base body 1, the outer side of the side plate base body 1 has a comb tooth port 101, and the inner side of the side plate base body 1 has a mounting plate 102; a comb tooth plate 2, the comb tooth plate 2 has a long hole 201 and a comb tooth part 202, the comb tooth part 202 exposes the comb tooth port 101; a fastener one 3, the comb tooth plate 2 is detachably arranged on the mounting plate 102 through the fastener one 3, and the fastener one 3 penetrates the long hole 201, and the extension line of the length direction of the long hole 201 penetrates the comb tooth port 101.

[0039] In this embodiment, during the assembly process of the side plate, the comb tooth part 202 of the comb tooth plate 2 is aligned with the comb tooth port 101 of the side plate base body 1, and the long hole 201 of the comb tooth plate 2 is aligned with the corresponding mounting position on the mounting plate 102, then the fastener one 3 is inserted through the long hole 201 of the comb tooth plate 2, and the comb tooth plate 2 is fixed on the mounting plate 102. During the installation process, the position of the comb tooth plate 2 can be preliminarily adjusted as needed, so that the comb tooth part 202 extends out of the comb tooth port 101 to an appropriate length. Compared with the traditional integral side plate structure, the side plate structure allows online adjustment to a certain extent. For example, when it is found that the crushing particle size does not meet the requirements, it is not necessary to completely stop the machine and disassemble the side plate and other complex operations. Only by appropriately loosening the fastener one 3, adjusting the position of the comb tooth plate 2 and then fastening again, the crushing particle size can be quickly changed, the influence on the production continuity is reduced, and therefore the extension line of the length direction of the long hole 201 penetrates the comb tooth port 101, so as to accurately control the length of the comb tooth part 202 extending out of the comb tooth port 101. This makes it possible to more accurately adjust the crushing particle size when facing different material characteristics or different crushing requirements, and improves the adaptability of the crushing effect.

[0040] And if the traditional side plate comb plate 2 is damaged or severely worn, the disassembly and replacement process can be more cumbersome, can involve more parts disassembly and complex operation steps, and can take a long time. The comb plate 2 of the side plate is detachably arranged on the mounting plate 102 by the fastener 1 3, and only needs to loosen the fastener 1 3 to quickly remove and replace the comb plate 2, greatly shortening the maintenance time and improving the maintainability of the equipment. The specific disassembly process is to loosen the fastener 1 3 so that it no longer fastens the comb plate 2 and the mounting plate 102, then remove the fastener 1 3 from the long hole 201, and then remove the comb plate 2 from the mounting plate 102 of the side plate base 1 to complete the disassembly of the comb plate 2. If the comb plate 2 needs to be replaced, a new comb plate 2 can be installed according to the above assembly process.

[0041] Further, the mounting plate 102 is a horizontal mounting plate 102, and the comb plate 2 further has an L-shaped mounting portion 203, the bottom of the L-shaped mounting portion 203 has a long hole 201, and the bottom of the L-shaped mounting portion 203 is detachably arranged on the mounting plate 102 by the fastener 1 3.

[0042] In this embodiment, the horizontal mounting plate 102 and the L-shaped mounting portion 203 of the comb plate 2 cooperate to provide a clear positioning reference for the installation of the comb plate 2, and are more stable. When welding and assembling, the operator can more intuitively align the bottom of the L-shaped mounting portion 203 with the horizontal mounting plate 102, making the installation process more convenient and accurate, reducing installation errors, and this structure can better disperse stress when subjected to impact force and vibration force during the crushing process, reducing the possibility of comb plate 2 loosening or displacement, and ensuring stable operation of the equipment.

[0043] The material of the side plate base 1, the mounting plate 102 and the comb plate 2 should have high strength and wear resistance to adapt to the harsh working conditions of coal, ore and other materials during crushing. For example, the side plate base 1 and the mounting plate 102 can be made of high-strength alloy steel such as Q345B, which has good comprehensive mechanical properties and can withstand large impact force and pressure. The comb plate 2 can be made of more wear-resistant materials such as high manganese steel (ZGMn13), which will harden the surface when subjected to impact and wear, further improving wear resistance and extending the service life of the comb plate 2.

[0044] The size of the horizontal mounting plate 102 should be reasonably designed according to the size of the side plate base 1 and the installation requirements of the comb plate 2. Its length and width should be able to stably support the comb plate 2, and when multiple comb plates 2 are installed, there should be a suitable gap between each mounting plate 102 to facilitate the flow and crushing of the material. The thickness of the mounting plate 102 also needs to consider its carrying capacity, which can generally be 10-20mm, and the L-shaped mounting part 203 of the comb plate 2 should be tightly matched with the horizontal mounting plate 102, and the length and width of the long hole 201 at the bottom should be designed according to the specifications of the fastener 3. The length of the long hole 201 should be able to meet the requirements of adjusting the position of the comb plate 2, and the length of the long hole 201 can be 30-50mm, and the width is 1-2mm larger than the diameter of the fastener 3, to facilitate the installation and adjustment of the fastener 3.

[0045] Further, the comb tooth part 202 and the long hole 201 are both several, and the several comb tooth parts 202 and the several long holes 201 are arranged in the width direction of the side plate base 1.

[0046] In this embodiment, the plurality of comb tooth parts 202 are arranged in the width direction of the side plate base 1, which can form multiple crushing points during the crushing of the material, so that the material is subjected to more uniform crushing force in the entire width range, avoiding the accumulation of the material in a local area or uneven crushing, thereby improving the consistency of the crushing effect and ensuring the uniformity of the product particle size, which is more conducive to subsequent material processing and processing.

[0047] Each comb tooth part 202 corresponds to a long hole 201, and the length of each comb tooth part 202 protruding from the comb tooth opening 101 of the side plate base 1 can be adjusted individually through the long hole 201. This allows for targeted adjustment of each comb tooth part 202 according to actual conditions when facing different material characteristics or different crushing requirements, achieving more precise and flexible control of the crushing particle size.

[0048] Further, it also includes: fastener 4, the L-shaped mounting part 203 has a mounting hole 204, the L-shaped mounting part 203 is detachably arranged on the side plate base 1 through the fastener 4, and the fastener 4 penetrates the mounting hole 204, and the fastener 1 and the fastener 4 are both high-strength bolt groups.

[0049] In this embodiment, the double fixing effect: through the fastener one 3 (high-strength bolt set) to fix the bottom of the L-shaped mounting part 203 on the horizontal mounting plate 102, and the fastener two 4 (high-strength bolt set) to fix the top of the L-shaped mounting part 203 on the side plate base body 1, through the mounting hole 204, the fixing of the comb plate 2 in two vertical positions is realized. This double fixing method makes the installation of the comb plate 2 on the side plate base body 1 more stable and reliable, can effectively resist the impact force and vibration force from all directions in the crushing process, reduce the risk of loosening, displacement and even falling of the comb plate 2, so as to ensure the stable operation of the equipment.

[0050] When it is necessary to maintain or replace the comb plate 2, whether it is because the comb tooth part 202 is worn or other components are damaged, the fastener two 4 can be disassembled first, the top of the L-shaped mounting part 203 is loosened from the side plate base body 1, and then the fastener one 3 is disassembled, the bottom of the L-shaped mounting part 203 is removed from the mounting plate 102, so that the comb plate 2 is conveniently disassembled as a whole. This step-by-step disassembly method is relatively simple to operate and convenient for maintenance personnel to operate.

[0051] Further, the comb tooth part 202 is trapezoidal in cross section, the L-shaped mounting part 203 has a gap 5 with the side plate base body 1, and further comprising: an adjusting gasket 6, the adjusting gasket 6 is arranged in the gap 5, and the comb tooth part 202 penetrates the adjusting gasket 6.

[0052] In this embodiment, the comb tooth part 202 is trapezoidal in cross section, which has a unique advantage in crushing materials. The inclined edge design of the trapezoid makes it easier for materials to be guided to the center of the crushing area during the crushing process, promoting the effective gathering and action of the crushing force on the materials in the crushing cavity.

[0053] The adjusting gasket 6 is arranged in the gap 5 between the L-shaped mounting part 203 and the side plate base body 1, and the comb tooth part 202 penetrates the adjusting gasket 6. By increasing or decreasing the number of adjusting gaskets 6, the protruding length of the comb tooth part 202 relative to the comb tooth opening 101 of the side plate base body 1 can be accurately changed. This fine adjustment method is simple to operate and has low cost, without the need for complex modification or replacement of large components of the overall structure of the side plate. In actual production, when it is necessary to adjust the crushing particle size according to different material characteristics or product particle size requirements, the operator can conveniently adjust the comb tooth protruding length by increasing or decreasing the adjusting gaskets 6 during equipment downtime, so that the equipment can quickly adapt to changes in production requirements, improving the flexibility and adaptability of the equipment.

[0054] Further, the adjusting gasket 6 is a plurality of adjusting gaskets 6, the plurality of adjusting gaskets 6 are arranged in the gap 5, and the adjusting gasket 6 is used to fill and support the gap 5.

[0055] In this embodiment, several adjusting washers 6 are arranged to fill the support gap 5. During the crushing process, the material will produce a relatively large impact force on the comb tooth part 202, and these impact forces will be transmitted to the side plate base body 1 through the comb tooth part 202. The adjusting washers 6 play a buffering role between the L-shaped mounting part 203 and the side plate base body 1, which can effectively absorb and disperse part of the impact force, reducing the direct effect of the impact force on the side plate base body 1. This helps to protect the side plate base body 1 from excessive impact damage, prolong the service life of the side plate base body 1, and reduce the maintenance and replacement costs of the equipment due to damage to the side plate base body 1.

[0056] Further, it further comprises a wear-resistant lining plate 7 which is detachably arranged on the side plate base body 1.

[0057] Further, the wear-resistant lining plate 7 is provided on both sides of the comb tooth opening 101.

[0058] Further, the side plate base body 1 has a connecting hole 103, and further comprises a fastener three 8, the wear-resistant lining plate 7 is detachably arranged on the side plate base body 1 through the fastener three 8, and the fastener three 8 penetrates through the connecting hole 103.

[0059] Further, the connecting hole 103 is provided on both sides of the comb tooth opening 101.

[0060] In this embodiment, the wear-resistant lining plate 7 is detachably arranged on the connecting hole 103 of the side plate base body 1 through the fastener three 8. During the crushing process of coal, ore and other materials, the side plate base body 1 is easily impacted and worn by the material. The arrangement of the wear-resistant lining plate 7 can effectively withstand the direct wear of the material, protect the side plate base body 1, and prolong the service life of the side plate. Since the wear-resistant lining plate 7 is directly in contact with the material, its material usually has high hardness and wear resistance, such as being made of high manganese steel, high chromium cast iron and other wear-resistant materials. Compared with the material of the side plate base body 1 (which may pay more attention to comprehensive performance such as strength), it can better resist wear and reduce the risk of failure of the side plate due to wear.

[0061] When the wear-resistant lining plate 7 is worn to a certain extent, the detachable design allows it to be quickly and conveniently removed from the side plate base body 1 for replacement without the need to repair or replace the entire side plate. This greatly shortens the equipment maintenance time, reduces the impact of equipment downtime on production, and improves the maintainability and availability of the equipment. At the same time, the cost of replacing only the wear-resistant lining plate 7 is relatively low, which helps to reduce the long-term operating cost of the equipment.

[0062] The comb tooth opening 101 is an important passage for material to enter and exit the crushing area, and is also a part of the side plate base body 1 that is more likely to be damaged during the crushing process. By arranging the wear-resistant lining plate 7 on both sides of the comb tooth opening 101, additional protection can be provided for the comb tooth opening 101 to prevent the material from causing wear and impact damage to the surrounding side plate base body 1 during the entering and exiting process. This helps to maintain the shape and size accuracy of the comb tooth opening 101, ensures the accuracy of the cooperation between the comb tooth plate 2 and other crushing components (such as toothed rollers), and thus ensures the stable operation and good crushing effect of the crushing equipment.

[0063] By arranging the wear-resistant lining plate 7 on both sides of the comb tooth opening 101, the wear of the side plate base body 1 in the area of the comb tooth opening 101 is effectively controlled, avoiding the local damage of the side plate caused by excessive wear in this area. At the same time, the presence of the wear-resistant lining plate 7 makes the wear of the side plate base body 1 more uniform in other parts, prolongs the service life of the side plate as a whole, reduces equipment failures caused by local damage of the side plate, and improves the reliability and stability of the equipment operation.

[0064] The shape of the wear-resistant lining plate 7 should be designed according to its installation position and protection range. Since the wear-resistant lining plate 7 is installed on both sides of the comb tooth opening 101, its shape is generally long strip-shaped or block-shaped, which is adapted to the shape of the comb tooth opening 101 and can cover the area around the comb tooth opening 101 that is prone to wear. The length direction of the wear-resistant lining plate 7 is consistent with the length direction of the comb tooth opening 101, and the width and thickness are determined according to the actual wear condition and the required wear resistance performance. Generally, the width can be between 50mm-200mm, and the thickness can be between 10mm-50mm, to provide sufficient thickness of wear-resistant material while not being too thick and heavy to affect the overall performance of the equipment. The edges of the wear-resistant lining plate 7 can be chamfered to avoid injury to the operator during installation and use, and also facilitate smooth flow of the material and reduce accumulation of the material at the edges of the lining plate.

[0065] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not limiting. Although the present utility model has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present utility model can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present utility model, and all of them should be covered in the scope of the claims of the present utility model.
