Abstract
Longitudinally extending nozzles are formed along a leading edge of the scraper blade of snow removal equipment to direct planar jets of air at a road surface to lift snow and ice from the surface of a roadway. A plate, in which pockets have been machined, is mounted on the ground engagement tool of the scraper blade to create the nozzles. The nozzles are connected to a source of compressed air mounted on the snow removal equipment.
Claims25
Apparatus for directing air at a surface for clearing the surface comprising:
- a first longitudinally extending substantially planar member;
- a longitudinally extending plate for mounting on the first planar member;
- one or more longitudinally extending nozzles formed between the first planar member and the longitudinally extending plate;
- and
- one or more inlets formed in one of either the first planar member or the plate and adapted for connection to a source of pressurized air,
- wherein the one or more inlets are fluidly connected to the one or more nozzles for flowing the pressurized air through the one or more nozzles for forming one or more substantially planar jets of air directed at the surface.
