Abstract
Briefly, disclosed is an ultra high pressure blasting head for a mobile marking removal system. The blasting head includes a hydraulic motor that is constructed and arranged for direct connection to a spray bar for controlled rotation thereof. The output shaft of the hydraulic motor is constructed to be hollow or tubular so that the ultra high pressure water can be supplied to the spray bar through the output shaft. The spray head assembly is particularly suited for mobile systems utilized to remove markings and/or coatings from surfaces with high or ultra high pressure liquid.
Claims12
A cleaning device for discharging fluid under high pressure towards a surface to remove coatings therefrom comprising:
- a blast head, said blast head having at least one nozzle constructed and arranged to deliver high pressure fluid toward a surface;
- said blast head having a shroud, said shroud having a top, sides and an open bottom;
- a fluidic motor mounted on said shroud, said hydraulic motor having a first fluid input and a first fluid output, said fluidic motor having a spindle passing through said fluidic motor;
- an inlet delivering high pressure fluid connected to one end of said spindle;
- said at least one nozzle fluidly connected to another end of said spindle;
- a second fluid outlet located on said spindle, said second fluid outlet being in fluid communication with said at least one nozzle;
- and
- said fluidic motor being driven by a plurality of gears located within said fluidic motor;
- said gears being in fluid communication with said first fluid inlet and said first fluid outlet, whereby fluid delivered to said fluidic motor drives said motor and spins said spindle, said nozzle connected to said spindle is rotated thereby to deliver high pressure fluid to a surface to remove coatings.
