Abstract

The invention provides a rotary cutting edge mounting structure for crusher and a crusher using such mounting structure, wherein the cutting edge portion is produced with a small size to improve the utilization ratio of resources, reduce the material cost of the cutting edge portion and allow the rotary cutting edge to be mounted on a rotor detachably conveniently. The crusher comprises a rotary rotor, a plurality of rotary cutting edges mounted on the surface of the rotor, and fixed cutting edges arranged on a housing to shear and crusher the crushed material between the rotary cutting edges, wherein the rotary cutting edge mounting structure for crusher comprises a plurality of mounting grooves processed on the surface of the rotor and provided with an even surface on bottoms thereof, wherein the rotary cutting edges are mounted on the inner side of the mounting grooves; the bottom surfaces of the rotary cutting edges are formed as even surfaces, and the rotary cutting edges are provided with a cutting edge portion for shearing and crushing the material to be crushed; the cutting edge portions are substantially triangle-shaped on front side faces formed as front sides thereof relative to the rotating direction of the rotary cutting edges.

Description

technical field [0001] The invention relates to a rotating blade installation structure of a crusher for shearing and crushing waste wood, waste plastics, old paper, etc. Install structure breakers. Background technique [0002] As an example of previous crushers, there are Figure 17(a) , Figure 17(b) The crusher shown (for example, refer to Patent Document 1). This shredder 1 is a shredder that shears and shreds objects to be shredded, such as waste wood and waste plastic, between a plurality of rotating blades 3 mounted on the surface of a rotor 2 and fixed blades provided on a fixing portion (not shown). And, if Figure 17(a) As shown, a plurality of plates 4 are detachably mounted on the outer peripheral surface of the rotor 2 with bolts 5 , and a plurality of mounting grooves 6 are formed on the surface of each plate 4 . And the rotating blade 3 is welded and installed on each mounting groove 6 . These rotating blades 3 are the same rotating blades and include a b...
