Scraper System With Fixed Working-Angle Lift And Toothed Tool Assembly

Abstract

A riding machine for scraping floor surfaces includes a fixed working-angle lift assembly allowing upward and downward movement of a tool to/from the floor independent of rotation of the tool to/from a working angle. A slide assembly slides on pins or shafts in slots in the frame of the riding machine and includes a blade slide and a blade swivel that rotates relative to the blade slide on a shaft. Upward and downward movement and rotation are effected by hydraulic cylinders. A toothed tool assembly includes a tool base mounted to the lift assembly by a shaft, the tool base including a mounting point for one or more teeth for scraping, and a loading surface on a transverse rail for transmitting force from the riding machine to the teeth. The teeth are mounted with a face against the loading surface. A carbide insert on the teeth has a diamond profile.
