Mechanical tooth matched with pulverizer and used for waste disposal

Abstract

A mechanical tooth matched to a pulverizer and waste treatment, which includes a block-shaped tooth head body, and the upper surface of the tooth head body is a working surface, which is composed of a square concave plane in the middle and four corners It consists of a four-corner bevel formed from the outside to the inside and obliquely downward to the sides of the square concave plane. A hard alloy layer is welded firmly on the four corners of the plane; the middle of the square concave plane is vertically The bottom is provided with a positioning threaded through hole; the four side walls of the tooth head body are respectively tapered surfaces expanding obliquely from bottom to top, forming a tapered square block body with a large upper part and a smaller lower part; the four An embedded cylindrical cemented carbide block is arranged on the middle upper part of the side wall and below the junction of two adjacent sloped cemented carbide layers; the bottom surface of the tooth head body is a plane and forms an assembly surface with the four side walls; It has the characteristics of reasonable structure, convenient use and installation, good overall structure firmness, wear resistance, good fastness to the tooth seat, and reasonable structure combined with each other, thereby improving work efficiency and so on.

Description

technical field [0001] The invention relates to a mechanical tooth matched with a pulverizer and waste product treatment, and belongs to the field of crushing mechanical equipment for waste treatment. Background technique [0002] The pulverizer is a common waste treatment equipment, usually used for waste crushing such as wood, gravel or bulk waste. The mechanical teeth of the existing pulverizer are combined with the gear seat and connected with the drive pivot through the tooth seat. During work, the mechanical teeth collide with waste products such as trees and garbage, thereby crushing the waste products; The mechanical teeth of the pulverizer 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, the structural design is not enough.

Problems solved by technology

The mechanical teeth of the existing pulverizer are combined with the gear seat and connected with the drive pivot through the tooth seat. During work, the mechanical teeth collide with waste products such as trees and garbage, thereby crushing the waste products; The mechanical teeth of the pulverizer 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, the structural design is not enough. Reasonable, especially if the combination with the tooth seat is not reasonable enough, it is easy to cause the mechanical teeth and other parts to be impacted by waste materials, so that the structure of the tooth head of the entire mechanical tooth is damaged, so the tooth head needs to be replaced frequently, which affects work efficiency and increases The cost
