[0002] In many industries such as ore mining, building material processing and solid waste treatment, the crusher plays a very key role. It crushes various materials through cutters to meet the particle size requirements of subsequent production processes. However, the existing crusher cutters have a series of technical defects that need to be solved in actual application. First, the cutter head of the crusher cutter needs to be replaced frequently due to wear and tear during operation. However, the existing crusher cutter is inconvenient to replace, and the cutter body cannot be reasonably protected, which can easily be damaged.

[0003] After searching, the Chinese utility model patent with the authorization announcement number CN216419672U discloses a cutter for crusher, which comprises a detachably connected cutter seat and cutter blade. The cutter seat is formed with cutter teeth. The cutter seat and cutter blade are made of different materials. The cutter blade is multiple. The cutter blades are distributed on the two side surfaces of the cutter seat. The cutter blades are uniformly distributed around the center of the cutter seat. A cutter groove is provided on the cutter seat. The cutter groove is a dovetail groove. A cutter block is embedded in the cutter groove. The cutter block and the cutter blade are made of the same material. The cutter blade can be replaced, prolonging the service life.

[0004] The above-mentioned cutter has at least the following technical defects:

[0005] 1. The dovetail groove on the cutter seat has a cutter block embedded in it. The dovetail groove has a special shape and requires high processing precision. This means that when disassembling the cutter block, precise tools and operation methods are required due to the close fit between the cutter block and the dovetail groove. Moreover, the internal space of the dovetail groove is narrow, making it difficult to use disassembly tools. During disassembly, the cutter block or the dovetail groove structure of the cutter seat can be easily damaged.

[0006] 2. The detachably connected cutter seat and cutter blade are greatly affected by vibration and impact force during the operation of the crusher. After a long period of work, the connection part is prone to looseness. When the crusher is processing large and hard materials, high-frequency vibration will also occur, which will gradually loosen the connection part between the cutter seat and the cutter blade, causing the cutter blade to shift on the cutter seat and affecting the crushing effect.

[0024] The following is a specific embodiment of the utility model, and the technical scheme of the utility model is further described in combination with the drawings, but the utility model is not limited to these embodiments.

[0025] As Figures 1-4 shown, the utility model provides a cutter assembly for crusher, including the cutter seat 1 that sets up the mounting hole 4 in the center position still including multiple cutter teeth 6, the cutter tooth 6 is integrally formed with cutter seat 1, the thickness of cutter tooth 6 is less than the thickness of cutter seat 1, cutter block 3, multiple cutter blocks 3 are detachably installed on cutter tooth 6, protection plate 2, two protection plates 2 are installed in cutter seat 1 and bottom respectively, the protection plate 2 is used to limit the position of cutter block 3, and the through hole corresponding with mounting hole 4 is set up on protection plate 2.

[0026] The protection plate 2 is uniformly provided with the convex plate corresponding with the cutter tooth 6.

[0027] The protection plate 2 is uniformly provided with the convex plate corresponding with the cutter tooth 6.

[0028] One side of the convex plate is provided with the stop block 8 abutting with the cutter tooth 6.

[0029] The upper and lower ends of the cutter tooth 6 are respectively provided with the mounting groove 7, the cutter block 3 is provided with the groove 11, and the mounting block 12 matched with the mounting groove 7 is mounted on the inner wall of the groove 11.

[0030] The upper and lower ends of the cutter block 3 are respectively provided with the limiting groove 10.

[0031] One side of the convex plate is further fixedly connected with the limiting block 9 matched with the limiting groove 10.

[0032] The working principle of the device is: first, the tool holder 1 is installed in the corresponding position of the crusher through the center mounting hole 4. Then, the tool block 3 is installed on the tool tooth 6, and the installation of the tool block 3 is through the cooperation of the installation groove 7 on the upper and lower ends of the tool tooth 6 and the installation block 12 on the inner wall of the tool block 3 groove 11, so that the tool block 3 can be accurately installed on the tool tooth 6. At the same time, the protective plate 2 is positioned and installed on the upper and lower ends of the tool holder 1 through the positioning holes 5 uniformly distributed on it and penetrating the tool holder 1. The protective plate 2 is fixed in position with the tool holder 1 through the positioning holes 5 via bolts. The protruding plate on the protective plate 2 corresponds to the tool tooth 6. The limiting block 9 on one side of the protruding plate cooperates with the limiting groove 10 on the upper and lower ends of the tool block 3, further fixing the position of the tool block 3 and preventing it from shifting during work.

[0033] When the crusher starts working, the tool assembly with the tool block 3 starts rotating or performing actions such as extrusion on the material, and the tool block 3 contacts the material. Since the tool block 3 is detachably installed on the tool tooth 6 and has the limiting and fixing of the protective plate 2, the tool block 3 can stably crush the material. The crushing action of the tool block 3 can be cutting, tearing, extruding and other ways, which can crush large pieces of material into smaller particles.

[0034] When the tool block 3 needs to be replaced due to wear, the protective plate 2 is removed, and then the worn tool block 3 is removed from the tool tooth 6. The specific operation is to remove the installation block 12 in the tool block 3 groove 11 from the installation groove 7 of the tool tooth 6, and then the tool block 3 can be removed. Then install a new tool block 3, and then reinstall the protective plate 2 to complete the replacement process of the tool block 3.

[0035] In the device, the tool tooth 6 is integrally formed with the tool holder 1, so that the connection between the tool tooth 6 and the tool holder 1 is firm and can withstand a large crushing force. The protective plate 2 is installed on the tool holder 1 through the positioning holes 5, and the protruding plate, limiting block 9 and other structures on the protective plate 2 cooperate with the tool tooth 6 and tool block 3 to limit the tool block 3 from multiple directions, ensuring the structural stability of the tool assembly during work and reducing the loosening or damage of parts due to vibration and other reasons.

[0036] The tool block 3 is detachably installed, and through the cooperation of the installation groove 7 and the installation block 12 and the limiting groove 10 and the limiting block 9, the tool block 3 is easy to disassemble and install when it needs to be replaced, which facilitates the user to replace the tool block 3 in time after it is worn, reduces the maintenance cost and time, and improves the working efficiency of the crusher.

[0037] Two protective plates 2 are respectively installed at upper and lower ends of the tool holder 1, which not only can limit the position of the tool block 3, but also can play a certain protective role to the tool holder 1, the tool tooth 6 and the tool block 3, so as to prevent foreign matters from entering the connecting position of the tool tooth 6 and the tool block 3, avoid the damage of components or the influence on the normal work of the tool block 3 due to the entry of foreign matters, the convex plate and the stop block 8 and other structures on the protective plate 2 can also prevent the tool block 3 from accidentally falling off during the work process, and the safety of the tool assembly is improved.

[0038] The specific embodiments described herein are merely illustrative of the spirit of the present application. Those skilled in the art to which the present application belongs can make various modifications or supplements to the described specific embodiments or replace them with similar ways, but will not deviate from the spirit of the present application or exceed the scope defined by the appended claims.
