Combined material breaking tooth structure for waste treatment

Abstract

The invention discloses a combined material breaking tooth structure for waste treatment. The combined material breaking tooth structure is formed by combining a tooth head and a tooth seat, wherein the tooth head comprises a cuboid block-shaped body; two sides of the upper part of the block-shaped body are inwards retracted to form a working head part; a whole large hard alloy block with a forwards upwarp head sharp corner is inwards embedded into the sharp end part of the upper part of the working surface in the front in a tilting manner; slopes facing the outside of two sides of the middle part of the front surface of the block-shaped body are respectively arranged on the two sides, and cuboid hard alloy blocks are respectively embedded into the slopes; an arc-shaped transitional edge which extends into the block-shaped body in a tilting manner to the bottom is arranged at the lower part of the back surface of the block-shaped body; a downwards square groove is further formed in the back surface; a circular assembling through hole is formed in the middle of the square groove; the tooth seat is a tooth head base with an inwards sunken arc-shaped welding surface formed on the bottom surface and externally protruded arc-shaped surfaces formed on the front and rear sides; based on a middle line serving as a boundary on the upper surface of the tooth head base, a perpendicular concave gap where the tooth head is inserted is formed in one side, and an upwards protruded assembling pillar is integrally arranged on the other side; and a locating through hole located on the same central line with the circular assembling through hole is transversely formed in the assembling pillar. The combined material breaking tooth structure for waste treatment has the characteristics of reasonable structure and convenience for use and mounting, and the characteristics that the whole tooth head structure is high in firmness and wear resistance, so that the use cost is reduced, and the working efficiency is improved, and the like.

Description

technical field [0001] The invention relates to a combined scrap tooth structure for waste treatment, which belongs to the field of scrap machinery equipment for waste treatment. Background technique [0002] Shredder is a common waste processing equipment, usually used to crush waste, wood, gravel or bulk waste and so on. The crushing teeth of the existing shredder are combined by the tooth head and the tooth seat, and after the tooth seat is connected with the drive pivot, the tooth head makes collision contact with waste products such as trees and garbage during work, so that the waste products However, the tooth head of the existing crusher is made of hard metal material, and the structure of the tooth head is easily damaged under the impact and vibration of the material, even if the working head of the tooth head is made of hard alloy material, etc. , but due to the unreasonable structural design, especially the unreasonable combination with the tooth seat, it is easy ...

AI Technical Summary

Problems solved by technology

The crushing teeth of the existing shredder are combined by the tooth head and the tooth seat, and after the tooth seat is connected with the drive pivot, the tooth head makes collision contact with waste products such as trees and garbage during work, so that the waste products Crushing; however, the tooth head of the existing crusher is made of hard metal material. Under the impact and vibration of the material, the structure of the tooth head is easily damaged, even if the working head of the tooth head is made of hard alloy material, etc. , but due to the unreasonable structural design, especially the unreasonable combination with the tooth seat, it is easy to cause other parts of the tooth head to be impacted by materials, thereby damaging the entire tooth head structure, so the tooth head needs to be replaced frequently, which affects the work. Efficiency, increased cost of use
