Abstract

The utility model relates to a fixed cutter of a crusher, which is arranged on a cutter holder; both sides of the fixed cutter are provided with a plurality of cutter grooves; the fixed cutter is in a split structure, and the fixed cutter on both sides are respectively provided with bolt holes. In the utility model, the fixed cutter is designed into two halves, so that the cutter grooves on both sides can meet different assembly conditions, and the positions can be appropriately adjusted according to the bolt holes. Consequently, the fixed cutter on both sides is not mutually constrained, the workload of assembly and grinding is reduced, the processing precision requirements on parts are reduced, and the processing cost is effectively saved.

Description

Crusher fixed knife

technical field

The utility model relates to a fixed knife of a crusher.

Background technique

Crusher is one of the key equipment in biomass power generation. It is mainly used to cut and crush straw, cotton straw, bark, etc., and make full use of biomass energy to generate electricity. The crusher is designed with a knife holder to install the fixed knife. When the shaft drives the knife head to rotate, a cutting space is formed between the blade of the moving knife and the fixed knife. In this way, the moving cutting edge can shear and break the straw. . Since the gap between the blade of the cutter head and the fixed knife is very high, one is very small and the other is uniform, and the existing fixed knife is an integral structure, so the requirements for the installation and manufacturing process are very strict, and because the material is Die steel is difficult to process after heat treatment, and wire cutting is used for processing. If you want to adjust to the ideal gap, it is guaranteed by manual grinding. One is that the cost is high, the other is that the efficiency is low, the production cycle is long, and the quality is difficult to guarantee. Because the accumulative errors of the assembly can no longer be adjusted, the assembly positions are mutually restricted, which brings great trouble to the assembly and grinding work.

Utility model content

In order to solve the above problems, the utility model provides a crusher fixed knife that can be adjusted and meets different assembly conditions.

The technical scheme of the utility model is: the fixed knife is arranged on the knife holder, and several knife grooves are arranged on both sides of the fixed knife, and the fixed knife is a split structure, and bolt holes are respectively arranged on the fixed knife on both sides.

In the utility model, the fixed knife is designed into two halves, so that the knife grooves on both sides can meet different assembly conditions, and can also be properly adjusted according to the bolt holes. In this way, the moving knives on both sides of the fixed knife no longer restrict each other, which reduces the workload of assembly and grinding, and also reduces the processing accuracy requirements of parts, effectively saving the processing cost.
