Abstract: A ditch cleaning apparatus is formed by a prime mover driving a chassis having endless metal belts for moving along the bottom of a vertical wall ditch and supporting an upright frame having a rearwardly and upwardly inclined elevator depositing debris on a first horizontal conveyor discharging debris laterally of a ditch position. A second horizontal conveyor, supported by the frame above the chassis, receives loose soil from the elevating conveyor for deposit on the ditch bottom rearwardly of the chassis. Sweep wings extend forwardly in diverging relation from the depending forward end of the elevating conveyor to guide debris toward the entrance end of the elevating conveyor. An operator position in the frame, above the upper limit of a ditch to be cleaned, is provided with controls for moving the machine and its several operating components in a ditch cleaning action.

Abstract: A backhoe operated bucket is provided with an opening containing a screen frame opposite its scraper blade equipped loading opening for separating coarse material contained by soil excavated from a pipeline ditch and depositing fine padding soil on a pipeline in the ditch. A motor driven eccentric supported by the screen frame vibrates the screen frame in several directions to achieve a separation of fine and coarse material, the latter being deposited in the ditch above the padding soil.
