Abstract:
A trench-padding apparatus for maximizing conversion of excavated material to trench-padding material, wherein the trench-padding apparatus includes a lead assembly, comprising a feeder housing having a front rotating unit with protrusions, wherein the front rotating unit is attached to a frame of the trench-padding apparatus immediately in front of an elevator device adapted to receive and transport said excavated material to at least a first mesh screen attached to said frame, said screen configured and adapted for separating the excavated material into at least two grades of material, wherein the front rotating unit is adapted to force clumps of the excavated material between the front rotating unit and a base of the feeder housing to aid in reducing clump size, and wherein said apparatus further comprises means for transporting material that fails to pass through said at least first mesh screen to a location removed from said screen.
