Material spreading, levelling and comminuting mechanism - has plate-shaped levelling elements with surfaces orthogonal to rotary axis

摘要

The material distributing, spreading and levelling machine on a surface consists of a grader (2) with several U-shaped, oscillating elements (10) equipped with rolling edges (10''') adjacent to the surface to be treated. A horizontal revolving shaft (3) with radial arms (5) is located inside the U-shaped elements, which are flat bars and swing on axles (12) mounted in a frame (4). The axles are in line and parallel to the surface to be treated. USE/ADVANTAGE - For road building and repair, with simple, robust design, and high reliability.
