Branch crusher tooth head structure

Abstract

The invention discloses a branch crusher tooth head structure. The branch crusher tooth head structure comprises a square block-shaped tooth head body; the upper end surface of the tooth head body is a working surface; the working surface is formed by four corner parts symmetrically and aslant downwards connected to an inclined surface with a square end surface or an inclined arc surface in middle; the four corner parts form sharp knife corners upwards projected; the lower end surface of the tooth head body is an assembly surface; a positioning thread through hole is vertically and upwards formed in middle of the assembly surface; four side surfaces of the tooth head body are inclined surfaces inwards shrunk from top to bottom to form a four-cone body with an upper area larger than a lower area; and chamfering transition edges are respectively arranged at four corner edges among the four side surfaces. The branch crusher tooth head structure has such characteristics as reasonable structure, convenience for use and installation, good firmness of the whole tooth head structure, wear resistance, reduction of the use cost and improvement of the working efficiency.

Description

technical field [0001] The invention relates to a tooth head structure of a shredder, belonging to the technical field of shredder machinery. Background technique [0002] Shredder is a common shredding equipment, usually used for shredding trees and garbage. After the teeth of the existing shredder are connected with the drive pivot, they collide with trees and garbage during work, thereby crushing the materials; however, the teeth of the existing shredder are made of hard metal materials , 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 materials, but the structural design is not reasonable enough, it is easy to cause other parts of the tooth head to be impacted by the material , so that the structure of the entire tooth head is damaged, and it is often necessary to replace the tooth head, which affects work efficiency and increases the cost of use.
