MACHINE FOR CLEANING ROADS FROM SNOW AND ICE FORMATIONS Russian patent published in 2022 - IPC E01H5/12 E01H10/00 

FIELD: road surfaces processing and cleaning.

SUBSTANCE: invention relates to technical means of urban utilities and is intended for the processing and cleaning of road surfaces from compacted snow and ice. Machine for cleaning roads from snow and ice formations contains a base machine with a frame on which a hydraulic station is installed, a tank and pipelines for liquid reagents, a collector and sprinklers fixed on the frame of the machine, a tank with a conical bottom for bulk material, a mechanism for its supply and spreading device. The hydraulic station includes a pump for supplying liquid reagents and hydraulic motors for driving a bulk material feeder. Liquid reagent spraying devices and loose material spreading devices are made in the form of hydroabrasive jet heads. Loose material feed mechanism contains paddle feeder, pipeline, collector and is connected with jet heads by means of flexible pipelines. The tank for bulk materials is equipped with a vibrator and is mounted on the frame of the machine by means of anti-vibration supports.

EFFECT: increasing the efficiency of cleaning the road surface from snow-ice formations by creating the kinetic energy of a sand-liquid mixture jet, which ensures the destruction of the snow-ice formation layer due to hydrodynamic pressure and the penetration of the mixture to a solid surface.
