Coal mine automatic spraying dust removal device

The invention relates to the technical field of coal mine dust removal, in particular to a coal mine automatic spraying dust removal device. A dust interception mechanism and a sewage precipitation mechanism are arranged above a mounting bottom plate, the dust interception mechanism is used for adsorbing, collecting and intercepting dust in a coal mine tunnel by using water, and the sewage precipitation mechanism is used for filtering and separating a mixture formed by the dust and the water; Therefore, water can be recycled in the dust intercepting mechanism. The dust interception mechanism comprises an interception net mechanism, a spray pipe mechanism and an adsorption cotton mechanism which are sequentially fixed on the mounting bottom plate, the sewage precipitation mechanism comprises a mounting box body, and a precipitation chamber, a water collection chamber and a water storage chamber through which a mixture formed by dust and water sequentially flows are arranged in the mounting box body. The technical scheme is used for solving the problems that in the prior art, a spraying dust removal system is high in water source consumption, water resources are wasted, the dust removal effect is poor, and the dust removal requirement in a coal mine tunnel cannot be met.
