Mechanical tooth head for pulverizer and waste disposal

Abstract

The invention discloses a mechanical tooth head structure for a pulverizer and waste disposal. The mechanical tooth head structure comprises a block-shaped lock block body, wherein upwardly protrudinggranular cemented carbide welding layers are welded on the upper two symmetrical side portions of the lock block body. Outer protruding blocks integrated with the lock block body are arranged at themiddle positions of the two symmetrical sides of the lock block body, wherein the thickness of the outer protruding blocks is equal to the thickness of the lock block body. A hexagonal positioning single hole is formed in the upper middle position of the lock block body, and an assembly through hole is formed in the middle of the hexagonal positioning single hole. Surfaces inclined downwards and retracted inwards are arranged on the two symmetrical side surfaces of the lock block body, that is, the outer side surfaces of the granular cemented carbide welding layers. The mechanical tooth head structure has the characteristics of reasonable structure, convenient use and installation, good firmness of the overall structure, abrasion resistance, good binding strength with a tooth holder, reasonable combined structure, improved work efficiency and the like.

Description

technical field [0001] The invention relates to a mechanical tooth head structure, in particular to a mechanical tooth head for pulverizers and waste products 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 then 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 th...

Problems solved by technology

The mechanical teeth of the existing pulverizer are combined with the tooth seat, and then 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 tooth head structure of the entire mechanical tooth is damaged, so the tooth head needs to be replaced frequently, which affects work efficiency and increases The cost
