WORKING ELEMENT TO REMOVE SNOW AND ICE SLIPPERY COAT FROM SURFACE OF ROADS AND AERODROMES Russian patent published in 2010 - IPC E01H5/12 

FIELD: construction, road engineering.

SUBSTANCE: invention relates to machines for cleaning of compacted snow, snow and ice formations and glase ice from surface of roads and aerodromes. Working element for removal of snow and ice slippery coat from surface of roads and aerodromes comprises frame and cutting disks. Frame is arranged in the form of mouldboard equipped with two vertical front brackets with plate fixed on them and two vertical back brackets for fixation of mouldboard to support plate. In lower part of plate there are cutting disks arranged, every of which is installed on axis, with the possibility of free rotation around it, with angle of lower disk base inclination towards surface of snow and ice slippery coat of not more than 10°. Longitudinal axis of working element is arranged in horizontal plane with the possibility of rotation by angle of not more than 43° in direction of its movement. Along edges of mouldboard on its back side there are two royal wheels arranged, every of which is fixed to mouldboard by means of horizontal bracket and fork with axis, between support surfaces of which there are packets of adjustment gaskets arranged, and elastic knife is fixed along lower edge of mouldboard.
