Description
Technical Field
[0001] The utility model relates to the technical field of crushing machinery, and particularly relates to a split-type movable cutter for a crusher with a replaceable blade structure. Background Art
[0002] In the traditional crusher industry, as a core component, the performance of the movable cutter directly affects the crushing efficiency and the service life of the machine. For a long time, the movable cutter generally adopts an integral design, that is, the blade and the cutter body are integrally cast or forged. Although this design has a compact structure and high strength, it has significant limitations in actual use. The wear problem of the blade of the integral movable cutter is particularly prominent. Due to the continuous impact and friction of the material on the blade during the crushing operation, the blade will soon show wear, which will in turn affect the crushing effect and the equipment performance. At this time, the user has to replace the whole movable cutter, including the cutter body part that has not been worn, which undoubtedly increases the use cost. In addition, frequently replacing the movable cutter will also affect the production efficiency and increase the downtime.
[0003] To sum up, the traditional integral movable cutter has the problems of high cost and inconvenient maintenance. Therefore, there is an urgent need in the market for a design scheme of a split-type movable cutter for a crusher with a simple structure, convenient installation and disassembly, and high cost-effectiveness.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0022] In order to more clearly understand the above-mentioned objects, features, and advantages of the present utility model, the present utility model will be described in detail below with reference to the drawings and specific embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other. In the following description, many specific details are set forth to fully understand the present utility model. The described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.
[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments, and are not intended to limit the present utility model.
[0024] This embodiment discloses a split-type crushing machine moving knife with an innovative design of a detachable blade structure, and its structure is as Figures 1 to 2As shown in the figure, it mainly includes a tool holder 1 and a tool bit 2 assembly that matches it. A plurality of mounting seats 10 are arranged on the outer circumference of the tool holder 1, and the number of these mounting seats 10 exactly corresponds to the number of tool bits 2, ensuring that each tool holder 1 can be detachably connected to the corresponding tool bit 2, greatly improving the flexibility and convenience of use. Specifically, as Figure 1 shown, three mounting seats 10 are evenly distributed on the outer circumference of the tool holder 1. Correspondingly, the number of tool bits 2 is also three. Of course, according to the actual requirements of the crushing operation, the numbers of the tool holder 1 and the tool bit 2 can be flexibly adjusted to meet different production requirements.
[0025] The tool bit 2 is designed with an integrated solution, that is, the cutting edge and the tool body are integrated into one whole. This integrated design not only endows the tool bit 2 with excellent strength and durability, but also enables it to maintain stable performance when facing high-intensity crushing operations. When the cutting edge is worn due to long-term use, the user only needs to replace the tool bit 2 part without replacing the entire moving tool, which greatly reduces the use cost and significantly improves the maintenance efficiency.
[0026] To achieve a firm connection between the tool bit 2 and the tool holder 1, a first end face 100 is provided on the outer side of the mounting seat 10, and a first mounting hole 101 communicating with the outside is opened on this end face. Correspondingly, one end of the tool bit 2 away from the tool tip is the second end face 20, and a first fixing hole 21 matching the first mounting hole 101 is opened on the second end face 20. By fitting the first end face 100 and the second end face 20 together, and at the same time the screw passes through these aligned mounting holes and fixing holes, the tool bit 2 and the tool holder 1 are firmly fixed together, ensuring the smooth progress of the crushing operation.
[0027] To further enhance the connection firmness between the tool bit 2 and the tool holder 1, a first clamping step 102 is added to the first end face 100, and a second clamping step 22 matching the first clamping step 102 is designed on the second end face 20. When the tool bit 2 is connected to the tool holder 1, these two sets of clamping steps are buckled together, not only increasing the contact area, but also increasing the mutual limiting surfaces, thus forming an extremely firm connection structure, effectively preventing the tool bit 2 from loosening or falling off during the working process.
[0028] To further improve the connection firmness, a second mounting hole 103 perpendicular to the first mounting hole 101 is provided on the first clamping step 102. Correspondingly, a second fixing hole 23 matching the second mounting hole 103 is also opened on the second clamping step 22. By passing additional screws through these two sets of perpendicular mounting holes and fixing holes, the positional relationship between the tool bit 2 and the tool holder 1 is further fixed and limited, ensuring that they always maintain a tight connection state during work and will not loosen or shift.
[0029] In addition, in order to achieve the precise positioning and stable connection between the cutter head 2 and the cutter seat 1, a structure of clamping blocks 24 and clamping openings 104 is additionally provided on the first clamping step 102 or the second clamping step 22. These clamping openings 104 and clamping blocks 24 cooperate with each other, which not only makes the installation of the cutter head 2 more convenient and rapid, but also effectively prevents the cutter head 2 from shaking during the working process, further enhancing the stability of the connection.
[0030] On the side of the mounting seat 10 close to the cutter seat 1, a third end face 105 is provided, which is in close contact with the cutter head 2. This design not only ensures that the cutter head 2 can maintain a stable state and accuracy during operation, but also effectively prevents the cutter head 2 from shaking or shifting during the crushing operation.
[0031] In order to achieve the precise positioning and installation of the cutter seat 1 on the crusher, a special positioning groove 11 is provided in the inner ring of the cutter seat 1, and this positioning groove 11 is connected with the cutter shaft in a matching manner. Through this design, the cutter seat 1 can always maintain the correct position and angle during operation, thus ensuring the smooth progress of the crushing operation.
[0032] Finally, in order to further enhance the connection stability between the cutter seat 1 and the cutter shaft, a ferrule 12 is additionally provided on one side of the cutter seat 1. This ferrule 12 is tightly sleeved around the cutter shaft and is fixedly connected with the cutter seat 1, effectively preventing the cutter seat 1 from loosening or falling off during operation, and providing a strong guarantee for the smooth progress of the crushing operation.
[0033] To sum up, through a series of designs and innovations, a split-type crushing moving cutter with a detachable blade structure in this embodiment realizes the rapid replacement of the blade, reduces the use cost, improves the maintenance efficiency, and demonstrates excellent stability and accuracy.
[0034] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Therefore, any modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the technical solution of the present invention.
