にようになる。As shown in FIG. 1, the crusher 1 according to the present embodiment is provided with a cutting blade 2 having a novel shape on a fixed cutter portion 34 and a cutting blade 3 having a novel shape on a movable cutter portion 35. Is. Here, the cutting blade 2 corresponds to the first cutting blade in the present invention, and the cutting blade 3 corresponds to the second cutting blade. As shown in FIGS. 1 and 2, the cutting blades 2 and 3 are fixed cutter parts.
It is provided so as to cover substantially the entire area of the movable cutter portion 35 and the movable cutter portion 35 in the longitudinal direction. Note that an embodiment of the crusher including a cutting blade having a straight cutting surface can be easily understood by those skilled in the art, and thus the description thereof will be omitted. However, the cutting blade 2 is shown in FIG.
As shown by the solid line, the movable cutter portion 35 is diagonally crossed, that is, provided on a substantially diagonal line, and the cutting blade 3 is also provided so as to diagonally cross the fixed cutter portion 34 as shown by the imaginary line. Has been. Further, the cutting structure of the cutting blades 2 and 3 performs so-called shearing similarly to a commonly used scissor or a cutter used for cutting a piece of paper with an office or the like. Therefore, when showing the positional relationship between the cutting blades 2 and 3 in a state where the movable cutter portion 35 is fitted to the fixed cutter portion 34, the cutting blades 2 provided diagonally as shown by the solid line in FIG. , The cutting blade 3 shown by the imaginary line comes to follow.

説明する。Next, the crushing action of reinforced concrete or the like by the crusher 1 will be described. When the object to be crushed is crushed, the hydraulic cylinder 36 is driven to rotate the movable cutter portion 35 in the direction of arrow B as shown in FIG.
An object to be crushed, such as reinforced concrete, should be caught between the fixed cutter section (34). Following this state, when the hydraulic cylinder 36 is driven to drive the movable cutter portion 35 in the direction of arrow A, the movable cutter portion 35 approaches the fixed cutter portion 34 as shown in FIG. Is crushed by the projecting teeth 34a, 35a (see FIG. 8), that is, crushed. Also, the rebar is cut by the cutting blades 2 and 3,
The cutting action will be described in more detail with reference to FIGS.

る。By breaking the concrete of the reinforced concrete as described above, the reinforcing bars 5 are separated as shown in FIG. In addition, since the reinforcing bar 5 has a mesh shape, it may actually be sandwiched between the cutting blades 2 and 3 in an irregular direction, and a lump of concrete may be integrally attached to a part thereof. In any state, while the movable cutter unit 35 is being rotated in the direction of arrow A, as shown in FIG.
As shown in FIG. 3, the reinforcing bar 5 hooked between the crests 3b and 3c of the cutting blade 3 moves toward the trough 3a as the movable cutter 35 rotates in the direction of arrow A, and is unlikely to come off the cutting blade 3.

Rebar 5 is enclosed in the diamond-shaped space formed between and. From this state, when the movable cutter portion 35 is further rotated in the direction of arrow A, the reinforcing bar 5 sandwiched between the valley portions 2a and 3a is cut by the cooperation of the press contact blades 2 and 3. In addition, not all the reinforcing bars 5 are sandwiched between the troughs 2a and 3a during the crushing work, and some of them are cut as shown in FIG.
Some are cut outside b and 3c.

However, the cutting blades 2 and 3 extend over substantially the entire length of the fixed cutter portion 34 and the movable cutter portion 35 in the longitudinal direction, and further in the width direction. It is installed diagonally across. Therefore, a space for holding the cut rebar 5 and the crushed concrete is formed on both sides of the substantially central portion of the cutting blades 2 and 3, so that the work such as further pulling out while holding the cut rebar 5 can be performed. it can. Further, since the cutting blades 2 and 3 are formed with the valley portions 2a and 3a, it is possible to prevent the rebar or the like from coming off in combination with the fact that the cutting blades 2 and 3 are formed in the longitudinal shape as described above. The cutting work can be performed efficiently.

On the other hand, a trough is formed substantially at the center of the facing surface of each cutting blade. Therefore, when the movable cutter portion is rotated to hold the crushed object, the crushed object is sandwiched between the two valleys and can be cut while preventing falling. Further, after cutting, it can be sandwiched with other crushed materials in the space formed on both sides of the cutting blade.
