Abstract

A backfilling device for backfilling an open trench and padding a pipe within the trench has a lateral earth moving device and a sifting device. The backfilling device is attached to a tractor that moves the lateral earth moving device into a backfill spoil pile adjacent to the trench with the sifting device located above the trench. The lateral earth moving devices moves the backfill spoil material laterally into a rotating drum of the sifting device. Smaller particles of the backfill material fall through the rotating drum, which is also vibrating to backfill the trench and pad the pipe with backfill fines. The oversize debris in the backfill material continues to move laterally and falls out the end of the rotating drum to form a pile of large piece backfill material on the side of the trench opposite from the backfill spoil pile.
