Description

CYCLONE DUST COLLECTOR FOR WORKING DRILL

The present invention relates to a dust collecting device for drilling that prevents dust generated during a drilling operation from being scattered.

Recently, it is a tendency to remodel the old buildings by repairing and reinforcing them rather than demolishing them and rebuilding them. The government is also encouraging remodeling rather than reconstruction considering the economic conditions such as environmental burden.

In the past, reinforced concrete structures such as steel plates and carbon fiber have been used for repair and reinforcement of old buildings made of reinforced concrete. In order to fix these reinforcement materials to reinforced concrete, drilling works are essential , Drilling is also performed to install household appliances having piping such as an air conditioner or a boiler, or to fix small items for interior such as picture frames and lighting.

When drilling is performed using a drill, there is a problem that debris or powdery dust generated by the contact friction between the drill bit and the concrete is scattered and dispersed in the air.

These dusts can cause the drill to break down due to the penetration of concrete dust and steel chips generated during the drilling operation into the drill, which may reduce the useful life of the drill.

In addition, the concrete dust and small particle fragments scattered during the drilling operation are scattered by the drill, and this dust can be absorbed into the inside of the body when the operator inhales for a long time, which can damage the respiratory organs, There is a drawback that when the work is blown, the worker's body is traumatized.

In order to prevent such concrete dust, water is sprayed on the wall surface to be drilled and drilled using a drill. However, when the water is evaporated or absorbed by the concrete dust, There are disadvantages that affect.

In order to solve such a disadvantage, a dust collector mounted on a drill has been developed to prevent concrete dust. However, it is not compatible with a product manufactured by other companies, and a suction device for sucking concrete dust, such as a vacuum cleaner, It is troublesome to proceed with the work.

In addition, there is a problem in usability because it is formed separately from the drill.
