Auxiliary device for tunnel construction dust removal and using method thereof

The invention discloses an auxiliary device for tunnel construction dust removal and a using method thereof.The auxiliary device comprises a wind power mechanism, the wind power mechanism comprises three outer frames, the inner bottom face of each outer frame is fixedly connected with a mounting frame, and the inner top face of each mounting frame is fixedly connected with a placing frame; a driving motor is fixedly connected to the inner bottom surface of each placement frame, and fan blades are rotationally connected to the outer surface of one side of each placement frame. During use, the mounting pipes and the compression pipes can be conveniently spliced through the first connecting ring and the second connecting ring, after the two wind power mechanisms are connected with the output component, one wind power mechanism is placed at a tunnel exit, and the other wind power mechanism is placed at an actual construction position; and meanwhile, it is ensured that the two wind power mechanisms can synchronous
