FIELD: mechanical engineering; public service machinery. ^ SUBSTANCE: invention relates to machines and equipment designed for removing ice coat and compacted snow from motor roads and sidewalks. Proposed device consists of frame, screw with right-hand and left-hand helix spirals, two scrapers, support twin wheels, transmission of working members, lowering and lifting hydraulic cylinders, and rotor. Rotor consists of shaft on which disk saws are key-mounted at definite pitch. Saws are separate by hammers with attached plates with sharp edge hinge-mounted on axles passing through disk saws. Support gear wheels are installed on shaft from end faces of sliding bearings. Outer diameter of gear wheels exceeds outer diameter of disk saws and hammers with sharp edge plates. ^ EFFECT: increased capacity. ^ 4 dwg |
