Abstract
Description
Technical Field
[0001] This utility model provides a hammer blade for a wood shredder with high impact resistance and wear resistance, belonging to the field of wood processing machinery technology. Background Technology
[0002] Wood processing machinery refers to mechanical equipment used in the wood processing industry, commonly including wood shredders and wood screening machines. In the wood processing industry, wood shredders are a frequently used piece of equipment for crushing wood into small particles or powder. The hammer blades are a key component of the wood shredder, and their performance directly affects the shredding effect and the service life of the equipment.
[0003] Existing hammer blades can generally meet normal usage needs. Wood shredder hammer blades mostly adopt a one-piece cast structure. However, after a period of use, due to the continuous impact and wear of the wood on the hammer blades, they are prone to damage. Their impact resistance and wear resistance need improvement, leading to reduced shredding efficiency and increased equipment maintenance costs. Therefore, this utility model provides a wood shredder hammer blade with high impact resistance and wear resistance. Utility Model Content
[0004] The technical problem solved by this utility model is that the impact resistance and wear resistance of the hammer blades of the wood shredder with the one-piece cast structure need to be improved, as they are prone to damage, resulting in reduced shredding efficiency and increased equipment maintenance costs.
[0005] To solve the technical problem, the technical solution provided by this utility model is as follows: a hammer blade for a wood shredder with high impact resistance and wear resistance, including a hammer head, an integrally formed hammer handle at the bottom of the hammer head, an octagonal groove at the top of the hammer head, the side of the octagonal groove being inclined downwards, the bottom surface of the octagonal groove being rhomboid in shape, and four blades being equidistantly arranged circumferentially between the side of the octagonal groove and the top edge of the hammer head.
[0006] Furthermore, the hammerhead is made of high-strength alloy material.
[0007] Furthermore, the hammer handle has a mounting hole at its center.
[0008] Furthermore, the side inclination angle of the concave octagonal groove is 35°-55°.
[0009] Furthermore, the cutter head is fixed to the side of the concave octagonal groove and the top edge of the hammer head by plasma welding.
[0010] Furthermore, the four sides of the hammer head are inclined outwards at an angle of 75°-85°.
[0011] The beneficial effects of this utility model are:
[0012] The inclined design of the four sides of the hammer head and the diamond-shaped bottom structure with an octagonal groove in the center enable the hammer blade to effectively disperse and absorb impact force when subjected to impact, reducing wear. The application of high-strength alloy materials and plasma cladding technology further improves the impact resistance and wear resistance of the hammer blade, ensuring that it can maintain high efficiency in long-term high-load working environment, is not prone to damage, improves crushing efficiency, and effectively reduces equipment maintenance costs.

[0019] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly mentioned in this specification are defined relative to their structure and are relative concepts. Therefore, they may vary depending on their location and usage; thus, these or other directional terms should not be interpreted as restrictive terms.
[0020] The singular forms “a,” “the,” and “the” used in this specification are intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes one or more of the associated listed items, any or all possible combinations thereof.
[0021] To make the technical problems to be solved, the technical solutions, and the beneficial effects of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described herein are merely illustrative and not intended to limit the scope of this application.
[0022] According to the appendix Figure 1-5 As shown: This utility model provides a high-impact and wear-resistant wood shredder hammer blade: including a hammer head 1, with an integrally formed hammer handle 2 at the bottom of the hammer head 1. The hammer head 1 and hammer handle 2 are manufactured by casting or forging processes. The hammer handle 2 has a mounting hole 5 in the center for fixing the hammer blade to the rotating shaft of the wood shredder. The hammer head 1 is made of high-strength alloy material, which has excellent impact resistance and wear resistance. The four sides of the hammer head 1 are inclined outward at an angle of 75°-85°. Specifically, the hammer head 1 is the main working part of the hammer blade and is made of high-strength alloy material to ensure its impact resistance and wear resistance under high-load working environment. It can effectively disperse the impact force of the wood and reduce the wear of the hammer blade.
[0023] As per the instruction manual Figure 1 , 2 As shown in Figure 3: The top of the hammer head 1 is provided with a concave octagonal groove 3. The side of the concave octagonal groove 3 is inclined downwards at an angle of 35°-55°. The bottom surface of the concave octagonal groove 3 is rhomboid in shape. Four cutter heads 4 are equidistantly arranged circumferentially between the side of the concave octagonal groove 3 and the top edge of the hammer head 1. This design not only increases the structural strength of the hammer head 1, but also provides an ideal fixed position for the installation of the cutter heads 4. The cutter heads 4 are clad and fixed to the side of the concave octagonal groove 3 and the top edge of the hammer head 1 by plasma cladding. Specifically, the hammer cutter head is heat-treated and surface-treated to further improve its impact resistance and wear resistance. The plasma cladding process ensures a firm connection between the cutter head and the hammer head, and improves the wear resistance and impact resistance of the cutter head.
[0024] The principle of this utility model
[0025] During use, the hammer blades rotate at high speed with the shaft during the wood crushing process, using the blade head 4 to cut and crush the wood. The inclined design of the four sides of the hammer head 1 and the diamond-shaped bottom structure of the concave octagonal groove 3 enable the hammer blades to effectively disperse and absorb impact force when subjected to impact, reducing wear. The application of high-strength alloy materials and plasma surfacing technology further improves the impact resistance and wear resistance of the hammer blades, ensuring that they can maintain high efficiency in long-term high-load working environments. The high impact resistance and wear resistance wood crusher hammer blades of this utility model are suitable for various wood crushers, especially when processing hard wood and high-moisture wood, their excellent impact resistance and wear resistance can significantly improve the working efficiency and service life of the wood crusher.
[0026] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
