ABSTRACT:
A wall scraping mixing tool for mixing, drying or reacting dry materials, semi-dry materials, or viscous, pasty materials with or without fillers or fibers, within the walls of a mixing container having a main shaft, and at least one support arm coupled to said main shaft. The mixing tool has a generally flat, rectangular plate mounted perpendicular to the radial plane of the support arm having a forward straight edge disposed adjacent to the container wall and a rear edge disposed away from the container wall so that the rectangular plate is inclined with respect to the container wall. There are two substantially triangular planes disposed on the rectangular plate, having side surfaces inclined relative to each other and connected at one edge thereof forming a wedge-shaped double-sided body for connection to the end of the support arm. The forward edges define a point located on the forward straight edge of the plate. The point rotates in the radial plane of the support arm connected to the main shaft of the mixing container. The side surfaces may be concave or convex in shape, and the tool can be constructed from a one piece casting of metal or fabricated as a weldment.
