Symmetrical mechanical tooth of crusher and for waste product disposing

Abstract

A symmetrical mechanical tooth of a crusher and for waste product disposing comprises a strip-shaped block body, point parts symmetrically protrude upwards from the upper portions of the two long endsides of the strip-shaped block body, granular hard alloy weld layers are subjected to build up welding from the point parts to the surfaces of the lower portions, and the interiors of the point partson the two sides transit downwards in arc shapes to a middle surface plane; a square block protruding downwards is arranged in the middle of the lower portion of the strip-shaped block body, assemblybottom faces of the strip-shaped block body are arranged on the two sides of the square block, and assembly through holes communicating with the middle surface plane are formed in the middle of the square block upwards; and the middles of the outer surfaces of the two long end sides of the strip-shaped block body protrude outwards, the upper portions and the lower portions of the outer surfaces of the two long end sides of the strip-shaped block body form inclined faces shrinking outwards correspondingly, and the granular hard alloy weld layers on the outer surfaces of the two long end sidesform the side faces with the middles of the lower portions being provided with n-shaped openings. The symmetrical mechanical tooth has the characteristics that the structure is simple, using and installing are convenient, the wear resistance of a tooth head can be greatly improved, the service life of the tooth head can be greatly prolonged, the using cost can be reduced, the working efficiency isimproved, and the material crushing rate is increased.

Description

technical field [0001] The invention relates to a pulverizer and symmetrical mechanical teeth for waste treatment, belonging to the technical field of material pulverizing machinery. Background technique [0002] Shredders are common item handling equipment, usually used to shred items such as waste, gravel, wood, and bulk waste. The mechanical teeth used in the existing shredders are connected to the drive pivot, and collide with the objects during work, thereby crushing and pulverizing the objects; however, the mechanical teeth used in the existing shredders basically use hard It is made of high-quality metal materials. Under the impact and vibration of materials, the structure of the tooth head of the mechanical tooth 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 damage. The other parts of the tooth head are impacted by the material, which damages the ...

AI Technical Summary

Problems solved by technology

The mechanical teeth used in the existing shredders are connected to the drive pivot, and collide with the objects during work, thereby crushing and pulverizing the objects; however, the mechanical teeth used in the existing shredders basically use hard It is made of high-quality metal materials. Under the impact and vibration of materials, the structure of the tooth head of the mechanical tooth 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 damage. The other parts of the tooth head are impacted by the material, which damages the entire structure of the tooth head. Therefore, the tooth head needs to be replaced frequently, which affects the work efficiency and increases the cost of use.
