Abstract

A device for filling an open trench with the dirt previously removed from the trench lying alongside the trench, using a skid-mounted frame having blades to initially fill the trench and leveling the dirt, followed by a compactor.

Claims

1. A device for filling an open trench with the dirt previously removed from the trench lying alongside the trench, comprising:

a skid-mounted frame having a forward end and a rear end and sized to span the open trench;

means in the forward end of the frame for moving the previously removed dirt generally into and over the trench;

means in the frame for temporarily leveling the dirt moved into and over the trench; and

means in the frame for compacting the temporarily leveled dirt.

2. The device of claim 1 for use with a towing vehicle wherein the skid-mounted frame includes brackets for attaching the forward end of the frame to a towing vehicle.

3. The device of claim 1 wherein the skid-mounted frame includes a vertical side plate at each side thereof and a skid along the lower edge of each side plate.

4. The device of claim 1 wherein the means in the forward end of the frame for moving the previously removed dirt generally into and over the trench comprises a pair of converging scraper blades adjustably supported in the frame.

5. The device of claim 1 wherein the means in the frame for temporarily leveling the dirt moved into and over the trench comprises a scraper blade extending across the frame.

6. The device of claim 1 wherein the means in the frame for compacting the temporarily leveled dirt comprises a compaction roller rotatably supported across the frame.

7. The device of claim 1 wherein the means for temporarily leveling the dirt comprises a rubber tired wheel rotatably supported in the frame.

8. The device of claim 7 further including a compression spring connecting the rubber tired wheel to the frame for urging the wheel toward the trench.

9. The device of claim 7 further including scraper blades mounted in the frame between the rubber tired wheel and the means for compacting the temporarily leveled dirt positioned to re-distribute dirt moved by the rubber tired wheel before the dirt is compacted.
