Abstract:
A screeding assembly for loose or plastic materials previously placed on the ground or another support surface, and especially placed and/or poured, uncured, concrete, said assembly adapted to be supported and moved along a path in a predetermined direction over an area of the material to be screeded, said assembly comprising:a support;an elongated rotatable auger having an axis of rotation generally transverse to said predetermined direction and mounted on said support to move the material laterally of said predetermined direction and grade the material;a vibratory screed mounted on said support and positioned behind said auger with respect to said predetermined direction to smooth the material;an elongated engaging member mounted on said support and positioned intermediate said auger and said vibratory screed to engage and smooth the material, and an oscillating assembly which reciprocates said engaging member in a direction generally parallel to said axis of rotation of said auger whereby the material is spread across said path, graded, and smoothed at a desired height above the ground/support surface by said screening assembly when said screening assembly is moved in said predetermined direction along said path; anda pivot axis extending generally parallel to said axis of rotation of said auger, said screeding assembly including said support said auger, said vibratory screed, and said elongated engaging member being pivotally movable about said pivot axis whereby contact of at least said vibratory screed and said elongated engaging member with the material being screeded may be varied and adjusted.
