Problems solved by technology

[0002] As we all know, the fixed knife design of the current high-speed crusher is to install a single row of knives on the rotating shearing position of the knife roller, so when the knife is working at high speed, it will only cut the material once per revolution, and the This undoubtedly has the problem of low fragmentation efficiency.

Abstract

The invention discloses a stationary knife structure which comprises a frame, first knife teeth and second knife teeth, the frame is provided with an arc-shaped surface, and the arc-shaped surface is provided with a reference end; the first cutter teeth are arranged on the frame, the first cutter teeth protrude outwards relative to the arc-shaped surface, and a first arc distance is formed between the first cutter teeth and the reference end in the circumferential direction of the arc-shaped surface; the second cutter teeth are arranged on the frame, the second cutter teeth protrude outwards relative to the arc-shaped face, a second arc distance exists between the second cutter teeth and the reference end in the circumferential direction of the arc-shaped face, and the first arc distance is different from the second arc distance. The first cutter teeth and the second cutter teeth are used for making contact with and colliding with the materials to be crushed, the materials to be crushed can be crushed at least twice in the process that the frame rotates by one circle, and therefore the effect of improving the working efficiency of crushing operation can be effectively achieved.

Description

technical field [0001] The invention relates to the field of crushers, in particular to a fixed knife structure. Background technique [0002] As we all know, the fixed knife design of the current high-speed crusher is to install a single row of knives on the rotating shearing position of the knife roller, so when the knife is working at high speed, it will only cut the material once per revolution, and the This undoubtedly has the problem of low crushing efficiency. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, the present invention proposes a fixed knife structure, which can improve the crushing efficiency. [0004] The fixed knife structure according to the embodiment of the first aspect of the present invention includes: a frame, a first knife tooth and a second knife tooth, the frame is provided with an arc-shaped surface, and the arc-shaped surface is provide...
