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.
  • 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 pitch circle element in cross-section substantially describes a% -Kreisausschnitt and includes the side edge of the Räummann from the front and from the side, and that the second pitch circle element in cross-section substantially describes a% -Kreisaus bainites and rests against the scraper from behind.
  • the most heavily loaded portions of the curb deflector are protected by a one-piece design of the% - circle part, while the% subcircuit element positively connectable -Teilnikelement used to stabilize and attach the entire curb repellent. 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 curb deflector prefferably screwed to the scraper blade, whereby a screw connection can be screwed through the scraper and the curb.
  • 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 curb deflector is screwed.
  • the fact that the screw head is sunk in the curb stone, the attack surface between snow and screw head minimized, so that a loosening of the screw connection is prevented. Since the associated nut is bolted in the opposite direction, ie against the direction of travel of the snowplow, behind the plow blade with the screw, this comes with the snow not in contact. Thus, a loosening of the screw and thus prevent falling of the curb deflector of the scraper.
  • 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.
  • Fig. 1 A 3D view of the scraper
  • Fig. 2 a plan view of the scraper
  • a scraper 1 is shown with a curb deflector 2 according to the invention.
  • the curb deflector 2 consists of a% partial circle element 3 and a ⁇ pitch circle element 4, between which the Scraper 1 is arranged.
  • the pitch 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% - part circle element 3 is placed from the front and from the side to the side edge of the scraper 1 and the VA- part circle element 4 from behind, against the direction of travel of the snow plow, applied to the scraper 1.
  • a screw 5 is now so pushed through the% - circle part 3, the scraper 1 and the VA pitch circle 4 that the screw head 5 is sunk in the% - part circle element 3 of the curb stone 2.
  • a nut 6 is screwed to the screw 5 so that the VA pitch circle element 4 of the curb deflector 2 rests firmly on the scraper 1.
