Abstract

The present invention relates to a breaker for a crusher or a breakage hammer for crushing a rock or a concrete structure, and more particularly, to a crusher for crushing a rock or a concrete structure by inserting a special metal 12 into a crushing portion 11 having a pointed tip at the tip of the chisel body 10 The breaker chisel is less worn and damaged, and the life span and the crushing efficiency are improved, so that crushing workability is very easily provided.

Description

My, wear-enhanced chisel {Chisel}

[0001]

      The present invention relates to a breaker for an excavator or a breaker hammer which crushes a rock or a concrete structure, and more particularly to a crusher and a tip of a chisel at a tip of a chisel body, The present invention relates to a chisel having excellent fracture efficiency by inserting a metal.

[0002]

Generally, breakers for excavators and chisels for destructive hammers are used for crushing rocks and concrete structures. [0003]

Such a conventional chisel is simply made of a cylindrical body, and a pointed crushing part is formed at the tip of the cylindrical body, so that the rock, concrete structure, and the like are crushed by the sharp crushing part.

[0004]

However, such a conventional chisel has a disadvantage in that the crushing efficiency of the crushing part of the tip of the cylindrical body is reduced due to wear and tear of the crushing part at the tip of the body due to friction that crushes the rock or concrete structure or the like.

[0005]

Furthermore, since the conventional chisel is simply formed in a cylindrical body shape, there is a problem that the end of the chisel is worn and damaged at the time of crushing operation of a rock or a concrete structure, shortening the life span and breaking efficiency.

[0007]

It is an object of the present invention to solve the above-mentioned problems of the prior art and to provide an excellent life of the breaker chisel by inserting a special metal at the tip of the chisel body.

[0008]

The present invention is characterized in that a special metal is inserted into a pointed shape at the tip of a cylindrical chisel body to enhance the fracture efficiency and prolong the service life.

[0009]

The present invention is an operation to increase the fracture efficiency by inserting a special metal into the tip of a crushing part and a crushing part at the tip of a chisel body, and it has an excellent working efficiency compared to the conventional chisel, It also has a very easy effect.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0012]

The special metal 12 is inserted into the end of the crushing part having the damage and abrasion preventing function of the present invention to increase the crushing efficiency and to prevent damage to the crushing part of the chisel.

[0013]

At this time, a special metal 12 is formed on the end 11.

[0014]

At this time, the special metal 12 is made of a stronger metal than the chisel body 10.

[0015]

Hereinafter, the operation and operation of the present invention will be described.

[0016]

The chisel of the present invention is mounted on a breaker or a breaking hammer of an excavator to crush rocks, concrete structures, and the like.

[0017]

In this crushing operation, crushing efficiency of the rock, concrete structure and the like is excellent due to crushing operation of the special metal 12 at the crushing part 11 having a pointed shape at the tip of the chisel body 10.

[0018]

That is, it has an excellent effect of improving the durability as well as the fracture efficiency as compared with the conventional cylindrical type chisel.
