When the second structure 420 is a steel plate, dust scattering and noise blocking effect Is superior to the mesh network, but has the disadvantage that the drilling process is covered by the steel plate, and when the second structure 420 is a mesh network, the dust scattering and noise blocking effect is weaker than that of the steel plate. It has the advantage of being able to observe the drilling process.

Therefore, the second structure 420 may be selectively configured as a steel plate or a mesh network according to the site situation.

In addition, in the drawings of the present invention, the second structure 420 is illustrated as a mesh network, and this is to make it easier to understand the operation relationship of other components, and the second structure 420 is a mesh network. It does not mean that only it is composed.

Referring to FIG. 6, the lower partial vibration prevention part 400 is configured to further include an open/closed structure 450, and the open/closed structure 450 is formed under the lower partial vibration prevention part 400 through a perforation operation. It is a configuration that opens and closes so that the slime discharged to the ground can be discharged to the outside of the lower partial dust prevention unit 400.

The slime discharged from the ground by the drilling work is accumulated on the ground, but if a large amount is accumulated, it interferes with the drilling work. Therefore, when a certain amount is accumulated, the accumulated slime must be discharged to the outside of the lower partial vibration preventing unit 400, and the manager opens the open/closed structure 450 to discharge the accumulated slime to the outside of the lower partial vibration preventing unit 400.
