欠点があつた。 Typically, a rotary shear crusher has a pair of fixed blades protruding from opposing parts of the crushing chamber surrounded by a casing, while the blades are mounted on a rotating main shaft that is rotatably supported in the crushing chamber. A rotary blade is attached to the table, and pulverized materials such as film, runners, plastic scraps such as defective molded products, and industrial waste materials are input from the material input port of the crushing chamber, and the rotary blade and fixed blade are separated by rotation of the rotating main shaft. The combined shear force is used to crush the material. However, conventionally, this type of rotary blade (so-called flat blade) has a cutting edge that is formed in a continuous straight line parallel to the axial direction of the rotating main shaft, so it can handle crushed materials of hard-to-catch materials and shapes, such as hard films. In this case, there was a drawback that the biting was poor, there was a high risk of slippage, and a good crushing function could not be achieved. On the other hand, there is a crusher that has a structure in which multiple mammoth blades are fixed to the rotating main shaft with their phases shifted to improve the efficiency of biting into the crushed material, but the materials and processing for the mammoth blades are expensive, and the assembly work is also difficult. It had the disadvantage of being time consuming.

された点にある。 In view of the above-mentioned problems, the present invention aims to improve the efficiency of biting into the crushed material and reduce the noise during the operation of the crusher. In a rotary blade for a rotary shear crusher that crushes the crushed material in cooperation with a fixed blade that is fixed to the rotating main shaft side and protrudes into the crushing chamber, the rotary blade has a blade in the longitudinal direction of the blade at the blade edge of the rotary blade. A plurality of concave stepped portions are formed along the rotary blade, and the outer edge of the bottom surface of the stepped portion is located on the rotational locus of the cutting edge of the rotary blade cutting edge portion to serve as the stepped cutting edge.

ある。 The embodiment of the present invention is constructed as described above, and a large number of edge portions 23 are formed on the cutting edge 21 of the rotary blade 17 when pulverizing the pulverized material. The edge portion 23 allows for efficient hooking and winding, thus preventing slipping of the pulverized material.
Biting efficiency can be greatly improved. Therefore, not only ordinary pulverized materials but also pulverized materials made of materials and shapes that are difficult to catch, such as hard films, can be efficiently and well pulverized, and a sufficient pulverizing function can be exhibited. In addition, since the outer edge of one side of the bottom surface of the stepped portion 22 is located on the rotation locus P of the cutting edge 21 to form the stepped cutting edge 24, each stepped cutting edge 24 and each fixed blade 8 cooperate with each other. The pulverized material can also be pulverized by the cutting edge 21 of each rotating blade 17.
The pulverization process can be carried out over the entire lengthwise direction, and no waste is produced. Furthermore, conventional rotary blades in which the entire surface of the blade edge is formed into a single plane have the disadvantage of generating a large amount of wind noise during rotation, but in this embodiment, when the rotary blade 17 rotates, each stage is Since the air is appropriately released through the portion 22, no large wind noise is generated, which has the advantage that the noise during operation of the crusher can be reduced.

The rotary blade 17 may be attached to each of the parts. Furthermore, the shape of the stepped portion 22 of the rotary blade 17 may be formed into an arcuate notch as shown in FIG. 5, and the depth, shape, and number of the stepped portion 22 are not limited to those in the embodiment. Further, the bolt insertion hole 25 may also be appropriately provided in correspondence with the blade mounting base 16.

Not only ordinary pulverized materials, but also pulverized materials such as hard films and other materials and shapes that are difficult to catch can be efficiently and well pulverized, and sufficient pulverization performance can be achieved. Further, as in the conventional case, the crushing process can be performed over the entire area of the rotary blade 17, so there is no waste. Furthermore, noise during operation of the crusher can be reduced. Moreover, it has a simple structure in which a stepped portion is formed on the rotary blade, and has the advantage of being easily manufactured.
