Combination scrap tooth structure for waste treatment

Abstract

A combined material crushing tooth structure used for waste processing is formed by combining a tooth head with a tooth holder. The tooth head comprises a blocky body with one side face shaped like a flag. The front face of the blocky body is a working face. Two hard alloy blocks which are connected in parallel and are each provided with a head sharp corner are obliquely embedded in the sharp end portion of the upper portion of the working face. Vertical inclined faces aligned with the outer lateral sides of the two head sharp corners correspondingly are arranged on the two outer sides of the front face of the blocky body. Long-strip-shaped hard alloy strips are embedded in the vertical inclined faces on the two outer sides and a vertical plane in the middle correspondingly. An inner concave part matched with the tooth holder and connected with the tooth holder in an inserted manner is arranged on the lower face of the blocky body. The tooth holder comprises a tooth base, wherein a connection end portion matched with the inner concave part of the blocky body is arranged on the front end portion of the tooth base, the rear end portion of the tooth base is in a conical shape, an outwards-protruding triangular part is formed in the middle of the upper portion of the tooth holder, and an arc-shaped welding face is arranged on the lower face of the connection end portion and the lower face of the tooth base. The combined material crushing tooth structure has the beneficial effects that the structure is reasonable, use and installation are convenient, the whole tooth head is good in structure firmness, wear resistance is achieved, the binding strength of the tooth head and the tooth holder is good, the mutually-combined structure is reasonable, and therefore the use cost is reduced, and the work efficiency is improved.

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 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 to cause other parts of the tooth head to be impacted by waste 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
