Abstract

(57) [Abstract] [Purpose] The concrete crusher is a skeleton bucket type to improve the efficiency of the crushing work of crushed objects. [Structure] A movable frame 3 having a plurality of claws is attached to a skeleton bucket 1 whose bottom portion is formed in a lattice shape, and the movable frame 3 operates a cylinder 8 to open and close with a shaft 7 as a fulcrum. A plurality of middle claws 5 are skeleton buckets 1.
The bottom grid is formed so that it fits in the grid 4. The claws 2 and 6 at the tip end are formed so as to mesh with each other, and an edge 9 is attached to the back of the skeleton bucket.

Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to a front attachment mounted on a shovel-type construction machine, and relates to a crusher used for secondary crushing such as dismantling of a building.

[0002]

[Prior art]

 After crushing concrete debris with a crusher attached to a conventional construction machine, sieving with a skeleton bucket attached to another construction machine, and crushing large concrete debris that could not be seen by the skeleton bucket grid again with a crusher Was.

[0003]

[Problems to be solved by the device]

 Conventionally, in order to make concrete debris smaller than a certain size by using only a crusher, the crushing work must be repeated many times, which requires sieving work with a construction machine equipped with a conventional skeleton bucket. The grid had to be re-crushed by a crusher for a large amount of concrete trash that could not be seen.

In addition, in the conventional bucket and skeleton bucket shapes, when pushing the concrete back, there is a radius, and the bucket often rides on the concrete back, making it difficult to use.

The present invention is capable of grasping and moving concrete debris and reinforcing bars, and by simply pressing and crushing a large number of concrete debris at one time, the crushing and sieving operations that were conventionally performed separately can be performed efficiently at the same time. The purpose of the present invention is to provide a concrete crusher with a wider range of use, such as improving work efficiency when pulling concrete debris backward.

[0006]

[Means for Solving the Problems] In order to achieve the above object, the present invention uses a skeleton bucket type crusher, in which the claws of the skeleton bucket and the claws at the tip of the movable frame are engaged with each other. The lattice part of the skeleton bucket and the movable frame provided with a plurality of claws are formed so as to crush and crush concrete trash.

An edge is attached to the back of the skeleton bucket.

[0008]

[Action]

 The above skeleton bucket concrete crusher was attached to the bucket arm of a hydraulic excavator, etc., and concrete shavings of various sizes scooped up by a skeleton bucket were pressed and crushed by a movable frame, and then passed through a grid to achieve a certain size You can get concrete trash.

In addition, by forming the claws of the skeleton bucket and the claws of the tip of the movable frame at the tip part, it is possible to grab and move concrete debris and rebar, and also pick up with the skeleton bucket. It can also be crushed without.

Since the edge of the skeleton bucket is attached to the back of the skeleton bucket, it is possible to bring concrete trash, rebar, etc. to the rear without the bucket riding on the concrete trash.

[0011]

【Example】

 In the embodiment shown in the drawings, the skeleton bucket 1 has a bottom portion of the bucket integrally formed of vertical and horizontal fixed beam members in a lattice shape, and a pawl 2 is formed at a tip thereof.

The movable frame 3 is provided with a plurality of inner claws 5 so as to fit in the lattice cells 4 of the skeleton bucket, and the claws 6 at the tip of the movable frame 3 are formed so as to mesh with the claws 2 of the skeleton bucket. . The movable frame 3 is driven onto the shaft 7, and the cylinder 8 is operated to open and close the shaft 7 as a fulcrum.

An edge 9 is attached to the back of the skeleton bucket.

By using a hydraulic shovel equipped with the skeleton bucket type concrete crusher as described above, the skeleton bucket 1 scoops up various sizes of concrete debris, and the size of the concrete debris that passes through the grid is downward. , And the remaining concrete debris remains inside the skeleton bucket 1.

Therefore, the concrete debris remaining inside is forcibly crushed by the movable frame 3 to forcefully pass through the lattice cells 4 and fall.

In addition, by engaging the claws 6 at the tip of the movable frame 3 and the claws 2 of the skeleton bucket at the tip part, it is possible to grab and move concrete debris and reinforcing bars, etc., without scooping up with the skeleton bucket 1. It can also be crushed.

When concrete glass or rebar is moved forward and the concrete glass is moved backward, it can be pushed by the edge 9 of the back of the skeleton bucket.

[0018]

[Effect of the invention]

 According to the present invention, a skeleton bucket type crusher can be used to scoop a large amount of concrete dust at one time. In addition, the concrete skeleton can be pressed and crushed to a certain size or smaller by forcing it through the mesh, so no skeleton bucket is required. Therefore, the time required for the crushing can be shortened to improve the efficiency of the crushing work, and vibration and noise can be reduced because there is no movement that occurs when the conventional skeleton bucket is used.

Further, since concrete scraps and reinforcing bars can be grasped and moved at the tip portion and can be crushed without scooping with a skeleton bucket, the range of use can be expanded.

The work efficiency when pulling concrete debris or reinforcing bars backward is improved.
