Pipeline padding machine attachment for a vehicle
First Claim
1. Self-contained padding vehicle attachment for attachment to a sub-frame of a vehicle for moving with the vehicle along one side of a ditch to pick up at least a portion of a pile of excavated material placed parallel to and along said one side of the ditch and processing the excavated material into padding material for placement in the ditch, the attachment apparatus comprising:
- a padding attachment comprising means removably connecting said attachment to the vehicle sub-frame at a position whereby said attachment is located at the front end of said vehicle and said attachment can be raised and lowered as desired to accommodate the padding operation;
a component part of said padding attachment having a moving framework with spaced openings, said openings being of a size to permit passage of suitable padding material therethrough while rejecting all other material as residual material, said framework further including a plurality of spaced excavated material engaging elements mounted to move with said framework whereby excavated material is scooped onto said framework;
a conveyor mounted on said padding attachment in a position to receive the suitable padding material passing through said framework, said conveyor being of sufficient length to extend over said ditch whereby said suitable padding material can be placed in said ditch.

Abstract
A padding machine attachment for a vehicle is provided. When padding of a ditch for a pipeline or cable is required, the padding machine is removably attached in a position at one end of a conventional bucket loader, bulldozer, or other base machine or vehicle, whereby said attachment moves along the path of travel of the vehicle. As the vehicle moves the padding machine attachment along one side of the pipeline ditch, the padding machine attachment picks up at least a portion of a pile of excavated material placed parallel to and along the same side of the ditch and processes the excavated material into padding material for placement into the ditch for padding the pipeline or cable.

4. A self-contained padding apparatus for moving along one side of a pipeline ditch, picking up excavated material from said one side of the ditch, and processing the excavated material into padding material for placement in the ditch, said apparatus comprising in combination:
-
a vehicle; and a padding attachment comprising means removably connecting said padding attachment to the front end of said vehicle whereby said attachment moves along the path of travel of said vehicle;
a component part of said padding attachment having a moving framework with spaced openings, said openings being of a size to permit passage of suitable pipeline padding material therethrough while rejecting all other material as residual material, said framework further including a plurality of spaced excavated material engaging elements mounted to move with said framework whereby excavated material is scooped onto said framework;

8. A padding apparatus for attachment to one end of a vehicle so that the vehicle can be moved alongside a trench while the padding apparatus processes soil into padding material, the padding apparatus comprising:
-
a support structure; attachment means for removably attaching said support structure of the padding apparatus to one end of the vehicle whereby the vehicle moves the padding apparatus along the path of the vehicle; lifting and screening means supported by said support structure to move around an endless path to carry soil upwardly as the padding apparatus is moved along the path of the vehicle and to selectively separate the soil into relatively fine padding material and relatively coarse residual material; and a transverse conveyor supported by said support structure and positioned at least partially within the path of said lifting and screening means to receive padding material that passes therethrough and to transport the padding material to the trench. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)
