An apparatus for sucking dust by spraying high-pressure water in a sublevel caving hydraulic support for sublevel caving hydraulic support

摘要

The utility model relates to a composite hydraulic chock high-pressure water mist duster, which is used for spraying and removing dust of composite working face chocks and coal placing openings. The utility model is composed of a spray pipe, a nozzle which is positioned the inner back part of the spraying pipe and on an axial lead, a dust pipe which is connected with the back end of the spraying pipe, etc., and the dust pipe can be a straight pipe or a U-shaped pipe. A sliver-shaped dust sucking hole is arranged on the pipe wall of the straight dust pipe which is connected with the spraying pipe to form a chock space duster, and the U-shaped dust pipe is a U-shaped bent pipe and is connected with the spraying pipe to form a coal placing opening dust remover. High pressure water is led into the spraying pipe from the nozzle which sprays mist, and the front end of the spraying pipe sprays mist and removes dust and the back end generates negative pressure to suck dust. The utility model has the advantages of small volume, little water consumption, low water pressure and good dust removing effect.
