Abstract

A dust suction hood includes a tapered outer cover, a cylindrical outer cover, a tapered inner baffle plate disposed in the tapered outer cover, and a first blocking member matched with an opening in the other end of the cylindrical outer cover. A top opening of the tapered outer cover is matched with an opening in one end of the cylindrical outer cover. A side wall opening of the cylindrical outer cover serves as a dust outlet. A first gap is formed in the tapered outer cover. A first dust suction port is formed between bottom openings of the tapered inner baffle plate and the tapered outer cover. A first drill pipe connecting port is formed in the first blocking member. A drill pipe of the mine drill passes through the first drill pipe connecting port to penetrate the dust suction hood on the drill pipe.
