Description

Technical Field

[0001] This utility model relates to the field of crusher technology, and in particular to a double-edged crusher blade. Background Technology

[0002] Currently, waste recycling crushers are widely used in industrial production, and the performance of their core component, the cutting tools, directly affects crushing efficiency and equipment operating costs. With increasing environmental protection requirements and growing demand for resource recycling, the frequency of use and maintenance costs of crushers have become a focus of industry attention. The durability and ease of maintenance of the cutting tools are key directions for technological development.

[0003] Current crusher cutters typically employ a single-edged cutter head design, with one side being the cutting edge and the other a fixed structure. When the cutter wears out, the machine must be shut down for repair or replacement. The repair process involves disassembly, grinding, or welding a new cutter head, which is time-consuming. Another solution is to use high-hardness materials to manufacture the cutter head, but this is costly and still doesn't eliminate the need for frequent maintenance. Furthermore, some equipment uses a symmetrical cutter body design, but the cutter head remains single-edged, preventing bidirectional use. Utility Model Content

[0004] Therefore, it is necessary to provide a double-edged crusher blade to address the problems of needing to stop the machine for repair or replacement after the blades wear out, which takes a long time and cannot be used in both directions.

[0005] A double-bladed crusher blade includes: a crusher body, a cutter shaft rotatably connected within the crusher body, and crusher blades mounted on the cutter shaft. The crusher blades are used to crush items placed inside the crusher body.

[0006] In one embodiment, the crusher cutter includes a cutter body disposed on the crusher body, and a plurality of fixed claws are evenly distributed on the surface of the cutter body, with cutting edges provided on both sides of the fixed claws.

[0007] In one embodiment, a pointed conical blade is provided between the fixing claw and the blade.

[0008] In one embodiment, a tapered portion is provided between the blade and the blade body.

[0009] In one embodiment, both the blade and the retaining claw are made of high-alloy tool steel.

[0010] In one embodiment, multiple sets of cutter shafts are provided, and the crusher body is provided with a drive device connected to the cutter shafts. The drive device includes a motor, a reducer, and a coupling, which is used to drive the cutter shafts to rotate and crush the materials.

[0011] In one embodiment, the cutter bodies on the two cutter shafts are arranged alternately.

[0012] In one embodiment, the internal cavity of the blade is hexagonal.

[0013] Beneficial effects The aforementioned blades feature a double-edged design, extending their service life to twice that of traditional blades. The crusher can crush materials in both forward and reverse directions, and the blades can be reused after wear in the forward direction, thus reducing operating costs. Furthermore, due to the conical section and pointed conical cutter head, the wear on the blade body and both sides of the cutting edge during crushing eventually forms a new conical structure, preventing a decrease in efficiency due to blade wear and reducing maintenance frequency. Additionally, the pointed conical cutter head provides greater crushing force. Attached Figure Description

The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0022] The following is combined with Figures 1-4 This invention describes a double-edged crusher blade.

[0023] In one embodiment, a double-edged crusher blade includes: a crusher body 101, a cutter shaft 102 rotatably connected within the crusher body 101, and a crusher blade 200 mounted on the cutter shaft 102. The crusher blade 200 is used to crush items placed inside the crusher body 101. The crusher blade 200 includes a blade body 201 disposed on the crusher body 101, and a plurality of fixing claws 202 are evenly distributed on the surface of the blade body 201. Each fixing claw 202 has a cutting edge 203 on both sides.

[0024] The rotation of the cutter shaft 102 drives the cutter body 201 to rotate, and the materials fed into the crusher body 101 are crushed by the action of the blades 203. When the blades 203 are damaged after long-term use, the rotation direction of the cutter shaft 102 can be changed, causing the cutter body 201 to rotate in the opposite direction, and the other blade 203 can continue to perform crushing, extending the service life of the cutter body 201, reducing the number of downtime maintenance, and facilitating use. Figure 4 As shown, the existing blade body 300 has multiple arc-shaped cutting edges 301 and blade backs 302 evenly arranged on its surface. The single-edged blade has a short service life and needs to be replaced frequently. The repair and replacement process causes equipment downtime and reduces production efficiency. After the blade becomes dull, it increases the load on the equipment and causes energy loss. This design has cutting edges on both sides of the fixed claw 202, which can crush in both directions, has a longer service life, and a longer maintenance cycle.

[0025] like Figure 2 , Figure 2 and Figure 3 As shown, a conical cutter head 204 is provided between the fixed claw 202 and the blade 203. The conical cutter head 204 is provided to improve the crushing effect and provide a higher crushing efficiency. A tapered portion 205 is provided between the blade 203 and the blade body 201. Both the blade body 201 and the fixed claw 202 are made of high-alloy tool steel. Multiple sets of cutter shafts 102 are provided. The crusher body 101 is provided with a drive device connected to the cutter shafts 102. The drive device includes a motor, a reducer, and a coupling, used to drive the cutter shafts 102 to rotate and crush the materials. The cutter bodies 201 on the two cutter shafts 102 are staggered. The internal cavity of the cutter body 201 is hexagonal.

[0026] In this embodiment, high-alloy tool steel undergoes secondary hardening and tempering at 500-550℃ to form M7C3 carbides, improving wear resistance. The surface nitriding layer is 0.1-0.3mm deep, with a hardness ≥1000HV. A motor drives a reducer to rotate, thereby reducing the motor speed and increasing torque. The cutter shaft 102 is connected to the output shaft of the reducer, driving the cutter body 201 to rotate. The cutting edge 203 then crushes the material. The motor, reducer, and coupling are all existing, mature components, selected as needed, and will not be elaborated further.

[0027] Working Principle: The blade body 201 is mounted on the cutter shaft 102, with the blade bodies 201 on the two cutter shafts 102 staggered to avoid collision. A motor drives the two cutter shafts 102 to rotate relative to each other, causing the blade bodies 201 to rotate relative to each other. The material to be crushed is placed into the crusher body 101, where the rotating blades 203 crush the material. The conical cutter head 204 improves the crushing effect and increases the crushing force. The conical section 205 ensures that during the crushing process, a new conical structure is eventually formed between the blade body 201 and the blade 203 on the fixed claw 202 side, preventing reduced efficiency due to blade wear and thus reducing maintenance frequency. If the blade 203 on the fixed claw 202 side breaks, the motor is reversed, causing the blade body 201 to rotate in the opposite direction, allowing the other blade 203 to crush the material until the other blade 203 breaks. This double-blade design extends service life, reduces maintenance frequency, and improves production efficiency.

[0028] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0029] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
