Wood chipper tooth head

Abstract

The invention discloses a wood chipper tooth head. The wood chipper tooth head comprises a square block-shaped tooth head body. The upper end face of the tooth head body is a working plane. The working plane consists of an arc-shaped end face which is formed in the way that a spherical body is tangent to the upper end face of the tooth head body, and convex sharp knife corners are formed at the four corners of the working plane. The lower end face of the tooth head body is an assembling plane. A counterbore hole is formed in the middle of the assembling plane, and a positioning threaded through hole is vertically formed in the middle of the counterbore hole in an upward mode. The four side faces of the tooth head body are all provided with oblique planes which are shrunken inwards from top to bottom, and accordingly a rectangular pyramid with the upper area being larger than the lower area is formed. Chamfer transition edges are arranged at the four corner edges of the four side faces. The wood chipper tooth head has the characteristics that the structure is reasonable, using and installing are convenient, the overall tooth head structure is good in firmness, abrasion resistance is achieved, and therefore the using cost is reduced, and the working efficiency is improved.

Description

technical field [0001] The invention relates to a tooth head 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.
