description The utility model provides a coal mining machine drum additional external spraying device based on a coal mine fully mechanized coal mining face, relates to the technical field of mining engineering, and aims to solve the problems that according to an existing spraying device, due to different densities of dust on a coal mine, the angle of a spraying head needs to be adjusted, spraying is carried out on a position with more dust, and if the angle of the spraying head cannot be adjusted, spraying cannot be carried out. The spraying and dust falling device comprises a bearing plate, wherein the bearing plate is arranged on the bearing plate; a clamping groove is formed in the middle of the top end of the bearing plate; the four corners of the bearing plate are each provided with a through round hole. A box body is placed in the clamping groove of the bearing plate; a through pipe hole is formed in the middle of the top end of the box body; symmetrical small covers are installed at the top end of the box body.
