The anti-spray equipment that leaks out of coal and rock of the present utility model, its power section all adopts source of the gas portion that the pneumatic means of power is provided, utilize same source of the gas to drive its work, its mode of operation can be mixed stirring and spraying to materials such as resinae water-repellent paints in proportion under the working condition of harshness;
The anti-spray equipment that leaks out of coal and rock of the present utility model, adopt pneumatic single-screw (single screw) pump 4 to drive extrusion screw rod 41, by the extrusion screw rod 41 of bleed pressure control and regulation, thus the conveying capacity of control and regulation conveying pipeline 51, both no pulse influences can unidirectionally transfer out the mixing material resin emulsion paint again continuously.
As a kind of embodiment, the anti-spray equipment that leaks out of coal and rock of the present utility model, described source of the gas portion 1 can be that air pump or load volume are the liquid gas storage tank of 1-3 kilogram.
Described pneumatic stirring pump 2 is the pneumatic stirring pump of 2.2-2.5KW for power.
Described cylindrical housings 31 is the cylindrical tube of 400-800L for volume.
Further, preferably, described paddle 33 is fixedly installed on steel blade on the teeter column for continuously spiral; Perhaps for evenly erectting the rectangle steel blade a plurality of not of uniform size that is fixedly installed on the teeter column both sides, the steel blade of its middle and lower part is greater than the steel blade on top.
As a kind of embodiment, described pneumatic spray gun 54 comprises gun body 55, spray material port 56;
Described spray material port 56 is arranged on the front portion of gun body 55, and described gun body 55 rear portions are provided with air inlet port 57 and charging aperture 58;
Wherein charging aperture 58 is connected with the efferent 53 of conveying pipeline 51, and air inlet port 57 is connected with air hose 6.
