Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

3 and 4 are exploded perspective views of the shredding disk according to the present invention.

As shown in Figures 3 and 4, the shredding disk (A) according to the present invention, a disc member formed by overlapping a plurality of first and second through holes 20, 40 having a seating groove 30 on one side (c), and a locking jaw 62 is formed on the upper surface, a support 6 inserted into and coupled to the seating groove 30, and blades 82 and 83 are formed at both ends, and the locking jaw 62 is formed. The stepped 86 is formed to be coupled to the support 6, it is composed of a cutter (8) installed in the first and second through holes (20, 40).

In more detail,

The disc member c includes a top plate 2 having a plurality of first through holes 20 formed at equal intervals, and a second through hole 40 coinciding with the first through holes 20. It consists of a lower plate (4) coupled to the lower portion of the fastener (5) for fastening the upper plate (2) and the lower plate (4).

5 is a plan view of the shredding disk according to the present invention.

3 to 5, the upper plate (2) is a circular plate-like, the center hole 22 is formed in the center is coupled to the axis (R2) of the rotating device (R), the rectangular first through hole 4 are formed symmetrically.

Here, the four first through holes 20 are divided into a through d through holes 201 to 204 for convenience of description.

The a and b through holes 201 and 202 are formed symmetrically on both the left and right sides with respect to the center hole 22, are formed adjacent to the outer peripheral end of the upper plate 2, and are formed so that the long sides are arranged horizontally. .

The c and d through holes 203 and 204 are formed symmetrically on both upper and lower sides with respect to the center hole 22, and are formed adjacent to the center hole 22, and are formed so that the long sides are vertically arranged.

The lower plate 4 has a circular plate shape having the same diameter as the upper plate 2, and a center hole 42 is formed at the center thereof to which the shaft R2 of the rotating device R is coupled, and has a rectangular second through hole 40. The four are formed symmetrically.

The second through hole 40 is formed to have a smaller size than the first through hole, and for convenience of description, the second through hole 40 is divided into e through h through holes 401 to 404.

Accordingly, the e through h through holes 401 to 404 constituting the second through hole 40 of the lower plate 4 are inserted into the through through holes 201 to 204 forming the first through hole 20 of the upper plate 2. The upper plate 2 and the lower plate 4 are overlapped to each other so that the fasteners 5 composed of bolts and nuts are combined and integrated.

In addition, the plurality of fastening holes 41 are formed on the long side of the second through hole 40, and a part where the fastening holes 41 are formed is exposed through the first through hole 20, and the exposed part is exposed. The support 6 and the cutter 8 will be a mounting groove 30 to be mounted (see Fig. 4).

6A and 6B are partial cross-sectional views of a shredding disc according to the present invention.

As shown in FIG. 4, the support 6 is a rectangular knitted body inserted into the seating groove 30, and a locking jaw 62 is formed at one side of the upper surface in parallel with the long side, as shown in FIG. 6A. Likewise, a detachable part 64 having a bolt hole 66 which is inclined downward from the other end of the upper surface and coincides with the fastening hole 41 is formed.

As shown in FIGS. 4 and 6A, the cutter 8 includes a body 80 having a plurality of holes 81 that are rectangular and coincide with the bolt holes 66, and both sides of the body 80. Comprising the blades (82,83) formed on the long side, the lower step of the body 80 is formed with a stepped jaw corresponding to the engaging jaw 62 on both sides.

Hereinafter, the binding and action of the present invention will be described.

The upper plate 2 and the lower plate 4 are connected to each other by overlapping the lower plate 4 to the lower portion of the upper plate 2 so that the first through hole 20 and the second through hole 40 coincide with each other. .

At this time, the fastening hole 41 formed at one side of the long side of the second through hole 40 is exposed to the outside through the first through hole 20 so that the seating groove 30 is formed.

Then, as shown in Figure 6a, after the support 6 is coupled to the seating groove 30, and seated so that the stepped jaw 86 of the cutter 8 is caught on the locking jaw 62 of the support (6) By fastening with the bolt 100, the blades 82 and 83 of the cutter 8 are installed to be inclined upward toward the first and second through holes 20 and 40.

In addition, as shown in Fig. 5, it is preferable that the blades 82, 83 of the cutter 8 are installed at positions covering about half of the first and second cylinder holes 20,40.

The crushing disk A in which the coupling is completed as described above is installed in the crushing device P and is connected to the rotating device R.

Therefore, the crushing disk A rotates at high speed in conjunction with the driving of the rotating device R, and when the object such as wood is input through the feeding unit 200, the crushing disk A is passed through the moving device 300. It collides with the cutter 8 and starts to be crushed.

That is, the chips cut and crushed by the blades 82 and 83 are discharged through the first and second through holes 20 and 40 and are discharged to the outside through the discharge port 4010 by the rotational force.

Since the impact force generated when the blades 82 and 83 collide with the object may be transmitted to the bolt 100 and at the same time, the impact force may be canceled by being dispersed in the stepped portion 86 of the cutter 8 and the latched portion 62 of the support 6. Impact force applied to the bolt 100 can be alleviated.

In addition, when one side of the blade is blunt, the cutter 8 is separated and then the other side of the blade can be used by changing the direction so that the operation can be performed continuously.

Although the present invention has been described in connection with the above-mentioned preferred embodiments, it will be readily apparent to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the invention, all such modifications and modifications being attached It is obvious that the claims belong to the claims.

As described above, according to the present invention, the impact force applied to the blade is transmitted and distributed to the support, thereby reducing the breakage rate of the bolt fixing the cutter, so that the durability can be significantly improved.
