System and method for pipeline padding

摘要

An apparatus for padding a pipeline lying in a ditch separates fine particles from coarse particles in the material excavated from the ditch and windrowed along the side of the ditch. The apparatus includes a frame having an open ended hollow separating drum having a plurality of scoop members adapted to lift and drop excavated material through a screen located beneath the scoop members. The scoop members are spaced above the screen a distance such that the efficiency of the separating drum is increased.
