Definitions

  • the invention relates to a scraper blade for the plow blade of a snow plow, which is provided at the top with a steel mounting neck for attachment to the plow blade.
  • a problem with using these scrapers is that the lateral end portion of the scraper bar, i. H. the area that clears the roadside of ice and snow, wears laterally. In particular, upon impact of the scraper on obstacles such. As curbs, this is damaged and thus reduced in their Räumbreite.
  • the ploughshare is already equipped with separate edge deflectors.
  • the object of the invention is therefore to provide a curb for a scraper, which is separately replaceable and yet enters into a solid connection to the scraper.
  • the invention proposes that at least at one side edge of the scraper a Randsteinabweiser is arranged, wherein the side edge of the scraper is inserted into a recess of the curb deflector.
  • the curb deflector is additionally reinforced by the scraper blade in it and a form-locking connection between the scraper bar and curb deflector manufactured, which has large support surfaces which extend transversely to the direction of the forces acting on the curb during broaching forces.
  • a tearing of the curb deflector of the scraper is almost impossible.
  • the curb deflector has a polygonal or rounded contour in cross-section and is preferably cylindrical. This shape of the curb deflector allows extensive protection of the Räumangnkante in all directions. Likewise, there are no additional edges that could catch on the obstacle and thus be damaged.
  • the invention provides that the Randsteinabweiser has in cross-section two pitch circle elements, which are so assembled to form a Retro Vietnameseneuveelement that the side edge of the Räumang between the pitch circle elements is arranged.
  • This two-part version of the curb deflector improves the positive connection of the Räumangnkante with the pitch circle elements of the Curb Repellent.
  • a particularly advantageous embodiment of the invention provides that the first part circle element in cross-section substantially describes a 3 ⁇ 4-circle cutout and the side edge of the Räummann from the front and from the side includes, and that the second part circle element in cross-section substantially describes a 1 ⁇ 4-circle cutout and rests against the scraper from behind.
  • This design protects the most heavily loaded portions of the curb deflector with a one-piece design of the 3 ⁇ 4 part circle element, while the 1 ⁇ 4 pitch element, which can be positively connected with the 3 ⁇ 4 part circle element, serves to stabilize and secure the entire curb deflector. Due to the positive connection of the scraper with the subcircuit elements a shifting of the individual parts is additionally prevented from each other.
  • the Randsteinabweiser is screwed to the scraper, with a screw so through the scraper and the Randsteinabweiser can be passed that a screw head in the direction of travel of the snowplow in the curb stone deflector is retractable and a nut in the direction of travel opposite direction behind the ploughshare and the curb deflector can be screwed.
  • the curb deflector consists essentially of a steel body, with which a plurality of hard metal pieces is materially connected, in particular soldered, is.
  • a trained curb scraper is due to the integrated carbide pieces very resistant to abrasive wear.
  • tungsten carbide which is already used for similar tasks, is recommended as hard metal.
  • the curb repellent can consist of a wear-resistant, hardened steel or chilled cast iron.
  • Chilled cast iron refers to a metastable cast iron with a high carbide content.
  • a scraper 1 is shown with a curb deflector 2 according to the invention.
  • the curb deflector 2 consists of a 3 ⁇ 4 pitch circle element 3 and a 1 ⁇ 4 pitch circle element 4, between which the Scraper 1 is arranged.
  • the pitch circle elements 3, 4 and the scraper 1 are bolted together by a screw 5 and a nut 6 attached thereto.
  • the invention works so that the two pitch elements 3, 4 are screwed to the scraper 1 so that a positive arrangement is created.
  • the 3 ⁇ 4 pitch circle element 3 is placed from the front and from the side around the side edge of the scraper 1 and the 1 ⁇ 4 pitch circle element 4 is applied to the scraper 1 from behind, against the direction of travel of the snow plow.
  • a screw 5 is now pushed through the 3 ⁇ 4 pitch circle element 3, the scraper 1 and the 1 ⁇ 4 pitch circle element 4 so that the screw head 5 is countersunk in the 3 ⁇ 4 pitch circle element 3 of the curb stone deflector 2.
  • a nut 6 is screwed to the screw 5 so that the 1 ⁇ 4 pitch circle element 4 of the curb stone 2 firmly abuts the scraper 1.
