Rake blade for use in e.g. snow shovel for clearing snow from streets, has lateral and rear limiting edge, where blade is formed from steel plate board made from steel alloy that is completely hardened or hardened only in partial areas

摘要

The blade (1) has a clearing edge (2) lying in a working direction, two lateral limiting edges (3) and a rear limiting edge (4), where the blade is formed from a single-piece steel plate board made from hardenable steel alloy that is completely hardened or hardened only in partial areas. A clearing strip is formed in U-shape in a cross-section and attached to the clearing edge. A flank is formed at the lateral limiting edges perpendicular to a blade surface (8). A fastening device made from steel is attached to a snow-clearing vehicle.
