In addition to being able to, there is an effect that the scattering dust can be removed locally.

In addition, according to the present invention, since the proximity of the suction unit to the source of scattering dust is achieved by remote control, the operator can freely select a location in the workplace to perform work in a state that sufficiently secures a view of the scattered dust generation point. , The risk of safety accident is small.

In addition, the movable scattering dust removal device according to the present invention is equipped with a container-type movable dust collecting device and a movable duct in consideration of practical mobility, so that it can be mounted or mounted on a vehicle or trailer configured as an integrated type to move.

It is obvious to those of ordinary skill in the art that the present invention is not limited to the described embodiments, and can be variously modified and modified without departing from the spirit and scope of the present invention. Therefore, such modifications or variations will have to belong to the scope of the claims of the present invention.
