(from the left side). Further, the serrated upper shearing blade 11 has each inclined portion 1 of the cutting edge.
1a are all formed in parallel. Moreover, all of the plurality of upper crushing blades 12 are inclined diagonally downward from the upper side to the lower side in the conveying direction of the object to be crushed.

However, as mentioned above, in the conventional hydraulic shearing crusher blade device, the distance between the tool rests 18 and 18 is narrower than the distance between the lower crushing blades 13 and 13, so the difference between FIGS. Turret 1 as shown
Since the material to be crushed 19 which has been sheared and crushed is sandwiched between the pieces 8 and 18, a force is required to push it out, resulting in a problem that the shearing and crushing performance deteriorates.

The present invention solves the above-mentioned conventional drawbacks, and has two
To provide a blade device for a hydraulic shear crusher, which is equipped with two crushing blades and prevents objects to be crushed that have been sheared and crushed from getting stuck between the tool rests of the lower crushing blades.

In order to achieve the above object, the cutter device of the hydraulic shear crusher of the present invention consists of an upper shearing blade and a lower shearing blade, which cut the material to be crushed in a direction perpendicular to the direction in which the material is inserted; A crushing blade that is provided on the downstream side of the direction and is composed of two pairs of an upper crushing blade and a lower crushing blade and cuts the object to be crushed in a direction parallel to the insertion direction; and a cylinder device that vertically approaches and separates the blade and the crushing lower blade, and the two crushing lower blades are
The two upper crushing blades enter between the two lower crushing blades and work together with the two lower crushing blades to perform the cutting operation. The cutting edges of the two upper crushing blades are each configured to be inclined in opposite directions to the horizontal direction, and the cutting edge of the shearing upper blade has a portion corresponding to between the two upper crushing blades extending in the horizontal direction. Moreover, both sides thereof are configured to extend diagonally downward.

According to this configuration, the distance between the two lower crushing blades and the distance between the two turrets can be made the same dimension, so that the sheared and crushed object does not get stuck between the turrets.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

FIG. 4 is a side view of a hydraulic shear crusher using a cutter device according to an embodiment of the present invention, and the same components as those shown in FIG. 1 are given the same reference numerals and explained. omitted. In Figure 4,
20 is a shearing force formed by an upper shearing blade 21 and a lower shearing blade 22; 23 is a pair of crushing upper blades 24 and a lower crushing blade 25;
The shearing blade 20 is a crushing blade consisting of
Further, the crushing blades 23 are respectively arranged downstream of the shearing blades 20 in the direction of insertion of the objects to be crushed along a direction parallel to the direction of insertion of the objects to be crushed. The upper shearing blade 21 and the upper crushing blade 24 are attached to the elevating member 10 with bolts not shown, and the lower shearing blade 22
is attached to a pedestal 26 that supports the receiving plate 3, and the lower crushing blade 25 is attached to a tool rest 27 by bolts not shown. As shown in FIG. 5, the blade edge of the shearing upper blade 21
A portion corresponding to between 4 and 24 is along the horizontal direction, and both sides thereof extend diagonally downward. Further, the cutting edges of the two upper crushing blades 24 are the upper crushing blades 24,
It is formed on the surface opposite to the facing surface of 24,
Therefore, the cutting edges of the two lower crushing blades 25 are formed on the opposing surfaces of the lower crushing blades 25, 25, and
7 and 27 support the crushing lower blades 25 and 25 from the side opposite to the opposing surface of the crushing lower blades 25 and 25;
The upper crushing blades 24 enter between the two lower crushing blades 25 and work together with the two lower crushing blades 25 to cut the object to be crushed. That is, the interval between the lower crushing blades 25, 25 and the interval between the tool rests 27, 27 are formed to have the same dimension. In addition, the upper crushing blades 24, 24 of the two plates
As shown in FIG. 4, the cutting edges of the blades are inclined in opposite directions with respect to the horizontal direction.

Next, the operation will be explained. When the object 19 to be crushed, such as coarse waste (for example, wood) that has been pre-compressed in the previous process, is pushed onto the receiving plate 3 in the direction of arrow A, the stamper main body 4 descends and the object 19 to be crushed is pushed into the stamper main body 4. It is firmly clamped and fixed between and the receiving plate 3. Next, the lifting member 10 descends, and the object 19 to be crushed is sheared and crushed by the shearing blade 20 and the crushing blade 23. In this case, the cutting edge of the upper shearing blade 21 is not serrated but symmetrical, In addition, two upper crushing blades 2
Since the cutting edges of No. 4 are inclined in opposite directions to the horizontal direction, the sliding force acting on the shearing upper blade 21 and the crushing upper blade 24 during shearing and crushing can be canceled out, and therefore the lifting member 10 The structure of the main body of the hydraulic shear crusher for controlling the position can be simplified. That is, in the conventional configuration, the upper shearing blade 11 slides in the direction of arrow B in FIG. As a result, the lifting member 10 attempts to move as it slides in the direction of arrow A in the figure, but in this embodiment, the shearing upper blade 21 cancels the sliding force by itself, and the crushing upper blade 24 Since the sliding forces cancel each other out, the force acting on the elevating member 10 is very small. After shearing and crushing, lifting member 1
0 rises, then the stamper body 4 rises,
The object to be crushed 19 is pushed in a predetermined distance again, and the object to be crushed 19 is sheared and crushed by a predetermined size by the same operation. Since the intervals are the same size, the object 19 to be crushed is sheared and crushed as in the conventional method.
does not get stuck between the tool rests 18 and 18, and therefore no force is required to push out the object 19 to be crushed that is stuck between the tool rests 18 and 18 during shear crushing, improving shear crushing performance. do.

As explained above, according to the present invention, the distance between the two tool rests can be made greater than the distance between the two lower crushing blades, so there is no risk of the sheared and crushed material getting stuck between the tool rests. Therefore, during shear crushing, there is no need to force the object to be crushed that is stuck between the tool rests.Moreover, both sides of the cutting edge of the shearing upper blade extend diagonally downward, and the two upper crushing blades The cutting edges of the blades are tilted in opposite directions relative to the horizontal direction, so that the sliding force acting on the upper shearing blade and the upper crushing blade during shearing and crushing can be canceled out, and the cutting can be done with one operation of the cylinder device. In combination with this, the shear crushing performance can be improved.
