Description of the Related Art Conventionally, a crushed object such as rock or concrete waste is visually divided by an operator by operating a hydraulic breaker attached to an attachment such as a hydraulic shovel. Moreover, the concrete waste material including the reinforcing steel material is cut and processed by a hydraulic cutter or the like. It may also be processed by crushing.

[0003]

When the object to be crushed is to be broken into small pieces by the hydraulic breaker, (1) the operator is required to have constant operation and skill of the hydraulic breaker.
(2) When a crushed object is processed by a crusher, the crusher has a limit to the size that can be charged, and a large-sized crushed object cannot be processed. Although large classifiers exist, they are expensive and uneconomical. (3) The conventional crusher has a problem that it is difficult to separate the concrete and the reinforcing bar material at the time of processing when processing the concrete waste material containing the reinforcing bar material.

The present invention is proposed in view of the above problems, and the object thereof is to automatically and quickly crush a crushed body, for example, a large lump of reinforced concrete or unreinforced concrete. Another point is to provide a crushing device capable of separating the crushed concrete and the reinforcing steel material at the time of crushing.

[0005]

In order to achieve the above object, the crushing apparatus of the present invention is provided with a crushing chamber into which an object to be crushed such as rock or concrete waste is put, and a crushing chamber that can be moved forward and backward. It comprises a crushing crushing plate provided, a hydraulic cylinder for moving the crushing crushing plate forward and backward, and a plurality of impact crushing breakers arranged on the crushing plate.

[0006]

The crushing apparatus of the present invention is constructed as described above, and the crushed object is put into the crushing chamber, and then each hydraulic cylinder is operated in the extension direction to push out the crushing plate for crushing. Operate the impact crushing breaker, collide the chisel at high speed with the crushed object, divide the crushed object into small pieces, then shrink the chisel of each impact crushing breaker, then operate each hydraulic cylinder in the extension direction The crushing plate for crushing and the fixed blade on the crushing chamber side crush the crushed object, shatter the crushed object, and discharge it from the discharge port at the bottom of the crushing chamber. The body, for example, large blocks of reinforced concrete or unreinforced concrete, can be automatically and quickly crushed.

If the object to be crushed is, for example, reinforced concrete, the reinforced material remains on the discharge port at the bottom of the crushing chamber, so that the crushed concrete and the reinforced material can be separated at the time of crushing.
