Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a crusher for crushing an object to be treated, such as earth and stones having a high water content, which has high adhesion.

[0002]

2. Description of the Related Art Since excavated soil excavated at a construction site contains clayey soil and weathered lumps of stone, it cannot be reused because it has no bearing capacity as a subgrade for backfilling. Therefore, these excavated soils have to be discarded, and the amount of waste is increasing due to the construction rush and heightening of the building in recent years. There is the problem of having to pay high costs. In addition, deterioration of the environment of the disposal site has become a problem. Therefore, in order to make it possible to recycle the excavated soil, the conventional method disclosed in Japanese Patent Laid-Open No. Sho 60
Devices such as those described in JP-A-48151 and JP-A-64-15151 have been proposed.

However, in the above-mentioned proposed apparatus, a stone block struck by a striking plate simply collides with a liner attached to a suspended chain (the liner and the chain constitute a colliding plate). If like goodwill,
By absorbing the collision energy, the most important purpose cannot be disintegrated, and the particles are dropped and discharged, so that there is a problem that sufficient regeneration processing cannot be performed.

In addition, in case the excavated soil adheres to a plurality of liners at the same time, a prime mover for bending the collision plate is provided to shake off the excavated soil.
Since the bending motion by this prime mover is not configured to be given to each of the links that form the chain,
The entire impact plate does not have an effective wiping action against the adhered matter, so that the adhering matter that flies temporarily drops at once, is discharged as a large lump, and is unstable in mechanical motion. There was a problem such as becoming.

[0005]

SUMMARY OF THE INVENTION Therefore, the present invention solves the above-mentioned conventional problems, maximizes the crushing effect, can sufficiently perform the regeneration process, and has an effect of shaking off. The object of the present invention is to provide a disintegrator capable of performing efficient treatment without agglomeration of the object to be treated and adhesion growth.

In order to achieve the above-mentioned object, the invention of claim 1 provides a crusher as described above,
A plurality of wear-resistant collision plates arranged in parallel in at least one side position of the rotor in the axial direction of the rotor, and pivotably supported at the upper or lower part of the casing so as to be swingable in the direction of coming into contact with and separating from the rotor; An operating member is provided which supports these collision plates and swings the supported collision plates so as to alternately approach or separate from the rotor at predetermined intervals. According to a second aspect of the present invention, in the first aspect, the collision plate is divided into a plurality of pieces in the height direction, and the divided collision plates are each swung by the operating member.

According to a third aspect of the present invention, in the crusher as described above, a plurality of mounting plates are arranged in parallel at least at one side of the rotor in the axial direction of the rotor, and are pivotally supported at the upper or lower part of the casing. To the rotor side surface of these mounting plates so that they can be attached and detached with wear resistant impact plates by means of mounting tools such as bolts.
An operating member is provided which supports the mounting plate and swings the supported mounting plate so as to alternately approach or separate from the rotor at predetermined intervals. According to a fourth aspect of the present invention, in the third aspect, the surface of the collision plate on the rotor side has a step shape. According to a fifth aspect of the present invention, in the third or fourth aspect, the mounting plate is divided into a plurality of pieces in the height direction, and the divided mounting plates are each swung by the operating member.

[0008]

As described above, since a plurality of collision plates arranged in parallel in the axial direction of the rotor are rocked by the actuating member so as to alternately approach or separate from the rotor at predetermined intervals, a plurality of objects to be fly-in are scattered. Even if it adheres to the collision plate, the adhesion area is divided and the adhesion area is reduced to reduce the adhesion force. Therefore, the attached matter is peeled off and dropped due to its own weight. Also, since the surface of the collision plate is in a state where there is no adhered material due to the above-mentioned separation of the adhered material and its own weight drop due to peeling, the effective crushing action does not reduce the collision energy that comes in the object to be processed. Can be continuously given.
