Description

[0001] SURFACE PROCESSING APPARATUS FOR STONE [0002]

The present invention relates to a stone surface machining apparatus, and more particularly, to a stone surface machining apparatus capable of preventing slippage by irregularly cutting a cut surface of a stone and adjusting the height of the polishing roller according to the thickness of the stone, The present invention relates to a stone surface machining apparatus capable of uniformly performing a machining process on a surface of a stone and preventing scattering of dust in the machining process.

Generally, stone such as a sidewalk block is processed so as to form irregular cut surfaces to prevent slipping, and this process is referred to as a Dod lock operation.

In general, the dod-lock operation refers to the operation of crushing the surface of a stone with a tool having a carbide attached to the surface of the stone.

When a stone is cut into a plate shape, the processed surface becomes smoother, and this smoothening operation smoothes the smooth surface for slip prevention and decoration.

In the conventional docking operation, it is usual that the operator uses a Dodrok hammer equipped with a cemented carbide portion on the bottom to manually bend the stone and finish the uniformly. Such a manual dodeclocking operation requires a lot of force and a great deal of attention Therefore, there is a problem that workability and productivity are deteriorated.

In addition, there is a disadvantage in that when a docking operation is performed by a striking method using a Dodrok hammer, the stone is shocked and crowded.

In order to solve the problem of the manual dodlock operation, the air hammer is used recently to perform the dodlock operation much more conveniently.

When the air hammer is moved to the part to be processed, the air hammer vibrates and strikes the surface of the stone.

However, the dodlock operation using the air hammer has the problem that the vibration force of the air hammer is transmitted to the worker because the worker is holding the air hammer, and the worker's body is impacted thereby causing a physical side effect.

Also, even if an air hammer is used, there is a disadvantage that a shock and a crowd are applied to a stone when a docking operation is performed by a hitting method.

In order to solve the above-mentioned problem, an apparatus for irregularly processing the surface of a stone by rotating a polishing roller has been developed.

BACKGROUND ART [0002] The background art of the present invention is disclosed in Korean Patent Registration No. 10-0767042 (published on September 7, 2007, entitled "Tool for Dodlock Device").

Since a general stone surface processing apparatus is difficult to variously change the height of the polishing roller, there is a problem that the height of the polishing roller must be manually adjusted by the operator depending on the thickness of the stone.

In addition, since a general stone surface processing apparatus is rotated in a fixed state in which the position of the polishing roller is fixed, there is a problem in that processing is not performed uniformly on the surface of the stone but processing is partially performed.

In addition, a general stone surface machining apparatus can not prevent the dust generated during the machining process on the surface of the stone from being scattered, and thus can not suppress environmental pollution caused by the operator and the surroundings.

Therefore, there is a need for improvement.

The present invention can prevent slippage by irregularly cutting the cut surface of the stone, and can adjust the height of the polishing roller according to the thickness of the stone to perform the machining process, and it is possible to perform the machining process evenly on the surface of the stone, And to prevent the dust from being scattered on the surface of the stone surface.
