である。2. Description of the Related Art In recent years, there have been various crushers for crushing concrete structural members such as walls and columns of structures (buildings and the like) made of reinforced concrete or the like. In many cases, a fixed jaw and a movable jaw are provided so as to be openable and closable by a hydraulic cylinder mechanism or the like, and the fixed jaw and the movable jaw are provided with cutting blades that open and close with the jaws to crush and cut concrete structural materials. .

The invention of the half-cut pearl-shaped cutting blade was already filed by the applicant in August 1981, and was subsequently published as Japanese Patent Publication No. 60-43513, which was later patented. This halved cutting blade cuts into a concrete structure sandwiched between a fixed jaw and a movable jaw in the form of a wedge when crushing a concrete structure, and as the bite depth increases, the concrete structure The structure is cracked, and the concrete structure is crushed as the cracks spread.

Concrete structures such as walls and columns can be crushed. In particular, in the type in which the above-mentioned side surface shape is trapezoidal, the front edge side is substantially right-angled, and the entire rear edge side is substantially arcuate, the movable jaw is sandwiched between the fixed jaw and the movable jaw is closed first. It comes into contact with the concrete structural material from the entire edge side, and the concrete structural material is crushed.

て有効である。[0006] The arc-shaped blade surface abuts on the surface of the concrete structural material over a relatively wide area, and the concrete structural material can be crushed while cracking the portion almost instantaneously. This is extremely effective when the internal structure of the concrete structural material itself is weak.

It becomes very hard and may have a very high resistance to crushing. When crushing such a hard concrete structural material, in particular, as described above, if the entire trailing edge is formed in a substantially arc shape, the contact portion between the movable crushing blade and the surface of the concrete structural material in the initial stage of crushing is used. , The crushing force is dispersed on the line-contacting contact surface, the crushing force is reduced in a unit area, and crushing becomes extremely difficult. Further, in the case of the conventional type, when the concrete structural material is crushed, slippage occurs and the concrete structural material is often displaced from the fixed jaw and the movable jaw, which hinders the crushing operation.

The state of the force that the movable crushing blade 5 exerts on the object S to be crushed, such as a concrete structural material, when crushing is described. First,
The object S to be crushed such as a concrete structural material generated by dismantling the structure with the fixed jaw main body 2 and the movable jaw main body 3 is added. Then, the movable jaw main body 3 is brought closer to the fixed jaw main body 2, and the movable crushing blade 5 comes into contact with the surface of the crushed object S such as a concrete structural material (see FIG. 4 (A)). At this time, the movable-side crushing blade 5, the small arc edge portion 5a around 1 comes into contact with the surface of the object to be crushed S such as concrete structural material, and small circular arc cutting edge 5

The contact state of the contact portion 1 with the surface of the crushed object S such as a concrete structural material is a point contact state (including a substantially point contact state).
Since the, in the initial stage to the crush material S concrete structural members or the like by the movable-side crushing blade 5, the crushing load becomes concentrated load by abutment of the small arcuate edge portion 5a 1 part. That is,
The crushing load is concentrated on the contact portion of the small arc blade tip portion 5a 1 without dispersing in substantially one place, so that even the crushed object S such as a concrete structure material having a hard surface has the contact portion as a center. It cuts in (see FIG. 4B).

する。According to the first aspect of the present invention, the fixed jaw main body 2 and the movable jaw main body 3 are provided on the crusher outer housing 1 so as to be openable and closable. the movable-side crushing blade 5 provided in, moving side crushing blades 5 is made from the rear edge portion 5a 2 and the tip edge portion 5a 3 Prefecture, small circular arc cutting edge 5
It said via a 1 rear edge portion 5a 2 and the tip edge portion 5a 3
And a trailing edge 5a continuously formed substantially in a right angle,
A leading edge 5b having substantially a large arc-shaped edge, the trailing edge 5a faces the inner side of the movable jaw main body 3, and the fixed jaw main body 2 has a predetermined interval along the longitudinal direction. A plurality of small crushing blades 6, 6,... Arranged in two rows having a plurality of small crushing blades 6 are arranged so that the blade line direction of each small crushing blade 6 is substantially orthogonal to the blade line direction of the movable side crushing blade 5. First, the crusher is suitable for crushing the object S to be crushed, such as a hard concrete structure material, and the concrete structure material and the like which are fixed by the fixed jaw main body 2 and the movable jaw main body 3 during the crushing operation. Can be reliably crushed without slipping,
Second, the structure has various effects such as being extremely simple.

ある。The trailing edge 5a of the movable crushing blade 5
Is connected to the trailing edge 5a 2 via the small arc edge 5a 1.
And a distal tip portion 5a 3 since it is substantially a continuum formed at a right angle shape with, contact with the surface of the crush material S becomes mainly abutment of the small arcuate edge portion 5a 1, minor arc cutting edge Part 5a 1
Has a very small radius, the contact state with the crushed object S such as a concrete structure material is point contact (including substantially point contact).
Becomes Therefore, in the initial stage of crushing to-be-crushed object S concrete structural members or the like by the movable-side crushing blade 5 of intensive by abutment to the crush material S concrete structural members or the like of the small circular arc cutting edge 5a 1 part The crushing load can be set, and the movable side crushing blade 5 can satisfactorily penetrate even the crushed object S such as a concrete structure material having a hard surface.

In, it is possible to increase the biting angle at which bite in the contact portion between the crush material S concrete structural members or the like of the small circular arc edge portion 5a 1. That is, the movable-side crushing blade 5 becomes wedge-shaped and bites into the crushed object S such as a concrete structural material while making it hard to slip. Therefore, there is the greatest advantage that the crushing operation can be made extremely efficient because the crushing load acts intensively and the concentrated portion becomes less slippery.
