When being processed, an object to be cut falling on the rotor blade 3 is smoothly guided and guided in the direction of the blade part 4 and 4 in a state where the centrifugal force action is sufficiently utilized, and such an unprocessed object to be cut. The state that the object is always supplied to the position of the blade part 4 is always maintained during the operation of the apparatus, which greatly assists the immediate cutting processing action by the rotor blade unit 2 described later. In particular, such an effect can be sufficiently obtained by forming an appropriate R shape as in the embodiment.

FIGS. 2-1, 2-2, and 2-3 are photographic diagrams illustrating an example of a procedure for overlapping rotor blades according to the embodiment of the present invention. Also,
FIG. 3 is a photograph showing the overall appearance of the rotor blade unit according to the embodiment of the present invention. As shown in these figures, in the shearing-type cutting structure 1 of the embodiment of the present invention, a plurality of rotor blades 3 are stacked and pivotally supported to constitute a rotor blade unit 2. The shearing-type cutting structure 1 is configured by including one or a plurality of receiving blades (not shown) provided outside the rotation radius of the rotor blade unit 2. Here, the rotor blades 3, 3,... Constituting the rotor blade unit 2 are provided such that adjacent ones are overlapped at different angles.

  As shown in these drawings, in particular, the rotor blades 3, 3,...

With this configuration, after the object to be cut is supplied into the apparatus, it is possible to increase the opportunity for this to be cut (crushed) by the blade part 4, and the processing at the previous rotor blade 3. The opportunity to process the unprocessed workpiece leaked from the container will be early, and the speed of processing and the certainty of processing will be improved.

    As illustrated, this angular change can be continuous. With such a configuration, the opportunity to process the unprocessed cut material in the above-described apparatus comes earlier, and the speed and reliability of the processing are further increased. Further, as in the illustrated embodiment, the angular intervals may be equal angular intervals. This is advantageous not only in terms of manufacturing cost and process, but also in terms of mechanism uniformity, durability, and maintenance management. In the embodiment, the rotor blades are overlapped so that adjacent ones are substantially orthogonal to each other, and every other blade is provided continuously and at different angular intervals.

  FIG. 5 is an explanatory diagram showing a positional relationship between the rotor blade unit and the receiving blade according to the embodiment of the present invention. In the drawing, the rotor blade unit shows only a part of the rotor blades constituting the rotor blade unit for the sake of clarity. As shown in the figure, the degree of crushing of the workpiece, that is, the particle size can be appropriately set depending on the distance (gap S) between the rotor blade 3a1 and the like and the receiving blade 6. For this purpose, the receiving blade 6 is preferably provided so as to be adjustable. Further, as shown in the figure, by providing the receiving blade 6 at two places, or three or more places, the number of cutting and crushing processing points increases, and the processing speed can be further increased.

FIG. 6 is an explanatory diagram in a plan view showing the method of changing the angle of every other rotor blade to be stacked in the embodiment of the present invention. Also,
FIG. 7 is an explanatory diagram in a side view showing the arrangement of the tip end portions (cutlery portions) of every other rotor blade arranged by the rotor blade arrangement method shown in FIG. 6. As shown in these figures, in the shearing type cutting structure 1 of this embodiment, the rotation angle formed by every other rotor blade 3A1, 3A2,... When the angle range of 90 ° between the rotor blades 3B1, 3B2,... Arranged orthogonally or substantially orthogonally is viewed from the end surface direction, a total of 11 rotor blades can be filled. .

  Further, as shown in the side view explanatory view of FIG. 7, every other pair of rotor blades is provided so as to reciprocate a total of 11 sheets when the 90 ° angle range is viewed from the end face direction. A total of 41 rotor blades (including one in the center overlap) and 20 rotor blades (not shown) of the other set provided between each rotor blade, and the rotor The blade unit 2 can be configured. However, the present invention is not limited to such specifications.

A rotor blade unit 2 is configured in which a plurality of rotor blades (such as 3) having any one of the above-described configurations are pivotally supported by being stacked in any one of the stacking methods, and the rotation radius of the rotor blade unit 2 is configured. One or a plurality of receiving blades (FIG. 5 receiving blade 6) are provided on the outer side to constitute the shearing cutting structure of the present invention.

FIG. 8 is a side view showing an embodiment of the shearing cutter according to the present invention.

  A cutting machine using the shearing-type cutting structure of the present invention was prototyped and its action and effect were tested. A shearing-type cutting structure was constructed based on the above-mentioned embodiment using 41 rotor blades having a plate thickness of 12 mm, and the workpiece was supplied to the apparatus for cutting treatment. All were crushed in one revolution of the rotor. Moreover, most of the workpieces have already been crushed by a single shearing operation by the rotor blade, and those leaked by the first shearing operation have been efficiently processed by the next rotor blade. Therefore, unlike the prior art, it is not necessary to rotate the apparatus indefinitely until the remaining unprocessed workpiece is subjected to the crushing process, and the remarkably high processing speed and processing efficiency have been confirmed.

  This also considerably reduces the size of the required motor. For example, if a 120 kW motor is conventionally required, the present invention can achieve the same capability with a 45 kW motor.

  The processing size of the workpiece can be determined by the thickness of the rotor blade. For example, when it is desired to set the processing size to 6 mm or less, the plate thickness may be set to 6 mm. The processing size was 3.2, 4.5, 6, 9, 12, 16mm, and the shearing-type cutting structure was manufactured and tested with rotor blades of each plate thickness. Moreover, the cutting (crushing) processing to a predetermined size with high accuracy was possible, and the result was good. Since the entire amount of the workpiece to be supplied can be efficiently miniaturized to a predetermined size, it is not necessary in the present invention to provide a sieve that has been necessary in the past.

  Further, the receiving blade can be processed with a size smaller than the plate thickness of the rotor blade by using a configuration in which the receiving blade can be freely inserted and removed.

  According to the shearing-type cutting structure of the present invention, the rotor blade constituting the shearing cutting structure, and the cutting machine, it is possible to cut an object to be cut (object to be crushed) to a desired size significantly faster and more efficiently than before. it can. In addition, the size of the crushing process can be freely set to a considerably fine size, and a crushing process with high uniformity can be performed. In addition, a screen equipment can be eliminated. Therefore, the invention has high industrial utility value. It can be used for cutting and crushing various wood resources, processing plastics, papers, and other materials that require a wide range of materials at extremely high speeds and with high accuracy.
