Mechanical tooth for crusher and waste product treatment

Abstract

The invention relates to a mechanical tooth for a crusher and waste product treatment. The mechanical tooth comprises a block-shaped body with an upper part as a working surface and a lower part as anassembling surface. Symmetrical triangular working blocks are externally and integrally connected to two corresponding side edges of the block-shaped body. The outer tip part of each triangular working block is obliquely and upwardly bulged to form a sharp corner part. At least one granular hard alloy welding layer is welded to the upper oblique and upward surface and the outer side surfaces of the two oblique edges of each triangular working block. A square convex block with a conical surface is arranged on the lower part of the block-shaped body. A vertically-upward positioning threaded hole is formed in the middle of the bottom of the square convex block. Transitional arc-shaped step surfaces are arranged on the portions, connected with the symmetrical triangular working blocks, of thetwo sides of the lower part of the block-shaped body, and a second-order assembly surface with the middle positioning threaded hole as the center and the two sides symmetrical is formed. The mechanical tooth has the beneficial effects that the mechanical tooth is reasonable in structure, convenient to use and mount, good in overall structure firmness and resistant to wear, so that the use cost islowered, and the working efficiency is improved.

Description

technical field [0001] The invention relates to a pulverizer and a mechanical tooth used for waste treatment, and belongs to the technical field of scrap machinery equipment. Background technique [0002] Shredder is a common waste disposal equipment, usually used for shredding trees and garbage. After the mechanical teeth of the existing pulverizer are connected with the drive pivot, they collide with waste products such as trees and garbage during work, thereby crushing the waste products; however, the mechanical teeth of the existing pulverizer are made of hard metal materials. However, under the impact and vibration of the material, the structure of the mechanical teeth is still easily damaged. Even if the working head of the mechanical teeth is made of cemented carbide, but the structural design is not reasonable enough, it is easy to cause damage to other parts of the mechanical teeth. The impact of the material damages the structure of the entire tooth head, and the ...

After the mechanical teeth of the existing pulverizer are connected with the drive pivot, they collide with waste products such as trees and garbage during work, thereby crushing the waste products; however, the mechanical teeth of the existing pulverizer are made of hard metal materials. However, under the impact and vibration of the material, the structure of the mechanical teeth is still easily damaged. Even if the working head of the mechanical teeth is made of hard alloy materials, the structural design is not reasonable enough, which can easily cause damage to other parts of the mechanical teeth. The impact of the material damages the structure of the entire tooth head, and the teeth often need to be replaced, which affects work efficiency and increases the cost of use
