More Information
Summary:The device has a leveling roller including multiple rollers, and a drive provided for a landing gear and the leveling roller, where a part of the tool is designed as freely rotating rotary bodies i.e. round shaped cutting discs. The rotary bodies are identically designed, where each rotary body is free-rotatably supported at an outside of a cylindrical shell (18) of the leveling roller. Rotation axes (20) of the rotary bodies run anti-parallel to a rotation axis of a support roller under angle of 10 degree. Selbstfahrende Straßenfräsen (10) und andere selbstfahrende Vorrichtungen zum Abtragen von Asphalt, Beton oder Gestein von Untergründen verfügen über eine Fräswalze (11) mit Spitzen aufweisenden Fräsmeißeln. Die Spitzen der Fräsmeißel verschleißen beim Abtragen von Asphalt, Beton oder Gestein sehr stark. Die Fräsmeißel müssen deshalb häufig gewechselt werden. Die Erfindung sieht es vor, die Fräswalze (11) mit frei drehbaren Schneidscheiben (19) zu versehen. Diese verfügen über umlaufende Schneidkanten (25), die infolge der freien Drehbarkeit der Schneidscheiben (19) im Vergleich zu bekannten Fräsmeißeln zu längeren Standzeiten führen.
