  According to the crushing device described in Patent Document 1, when the rotary blade 90 meshes with the fixed blade 92 from the cutting edge, the crushing object is like a ridge at two points of each facing blade portion with respect to the object to be crushed. Since the force acts, there is an advantage that the material can be smoothly crushed. However, when the object to be crushed is sheared by each blade, an improvement has been desired in that noise caused by vibration is large.

  The present invention has been made in view of the above-described problems, and an object thereof is to provide a crushing device, a fixed blade, a fixed blade portion, and a rotary blade that can improve crushing efficiency while reducing the power cost for crushing. And

  In order to achieve the above-mentioned object, the crushing device according to the present invention is characterized in that a plurality of rotary blades arranged in the axial direction are fixed to a peripheral surface as described in claim 1 of the claims. A crushing apparatus comprising a crushing processing unit in which a crushing rotor and a plurality of fixed blades that mesh with the rotary blade as the crushing rotor rotates are arranged to face each other along the axis. The blade includes a rotating blade portion that is paired so as to be continuous at a predetermined cutting edge angle, and a fixed blade portion that is paired so as to mesh with the paired rotating blade portion. , One of the rotary blade portions is engaged with one of the fixed blade portions from the blade base, and the other of the rotary blade portions is engaged with the other of the fixed blade portions from the blade edge. .

  According to the configuration described above, when the rotary blade and the fixed blade are engaged with each other, one of the rotary blade portions is engaged with one of the fixed blade portions from the blade base, and the other of the rotary blade portions is in contact with the other of the fixed blade portions. Because the blades mesh with each other, the crushing object is sheared by each blade, so that a force acts like a heel at one point, so that the crushing rotor can be rotated with a small torque so that it can be crushed very smoothly. Thus, not only vibration and noise can be reduced, but also the power cost can be reduced.

  The second characteristic configuration is that, as described in the second aspect, in addition to the first characteristic configuration described above, the elevation angles of the pair of fixed blade portions are set to different angles.

  According to the above-described configuration, first, one rotary blade portion meshes with the fixed blade portion having a large elevation angle from the blade base, and then the other rotary blade portion meshes with the fixed blade portion with a small elevation angle from the blade edge. As a result, a force always acts on the object to be crushed at one point.

Although it becomes expensive, according to the above-described configuration, the labor of processing is reduced. For example, in the case of processing so that the first fixed blade part is formed flush with the surface of the plate-like body that is the material, a wide range of plate-like bodies required to form the second fixed blade part Therefore, it is only necessary to form a concave mounting seat.

  In the fifth feature configuration, as described in claim 5, in addition to the third feature configuration described above, a plurality of concave mounting seats are formed along the end portion of the flat plate-like support portion. The first fixed blade portion and the second fixed blade portion that are formed are in such a manner that they are alternately inserted into the mounting seat and fastened.

  According to the above-described configuration, it is not necessary to use an expensive material such as tool steel or cemented carbide for the support portion, and only the tip members constituting the first fixed blade portion and the second fixed blade portion are tool steel or cemented carbide. Etc. may be used, and even when the blade is worn, it can be easily replaced.

  In addition to any one of the first to fifth feature configurations described above, the sixth feature configuration includes the pair of rotary blade portions in a side view of the crushing rotor. The difference is that it is set at a different angle with respect to the radial direction.

  Even if the rotary blade is set to a different angle with respect to the radial direction of the crushing rotor instead of the fixed blade, one of the rotary blades meshes with one of the fixed blades from the blade base and rotates. It can comprise so that the other of a blade part may mesh | engage from the blade edge with respect to the other of a fixed blade part.
