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 dirt previously removed from the trench lying alongside the trench, comprising:

a frame having a forward end and a rear end, the frame sized to span the open trench and the dirt lying alongside thereof, the frame having a vertical side plate at each side thereof and a skid along the lower edge of each side plate for facilitating movement of the device along the open trench;

a pair of rearwardly converging blades supported by the frame for engaging and moving the previously removed dirt generally into and over the trench, the pair of rearwardly converging blades adjustably supported on the frame on either side of an axis that extends from the forward end of the frame to the rear of the frame such that the spacing between rear end portions of the rearwardly converging blades is adjustable inwardly and outwardly relative the axis; and

a compaction roller rotatably supported in the rear end of the frame for compacting dirt moved into and over the trench.

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

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

a frame having a forward end and a rear end, the frame sized to span the open trench and the dirt lying alongside thereof, the frame having a vertical side plate at each side thereof and a skid along the lower edge of each side plate for facilitating movement of the device along the open trench;

a pair of rearwardly converging blades supported by the frame for engaging and moving the previously removed dirt generally into and over the trench, the pair of rearwardly converging blades adjustably supported on the frame on either side of an axis that extends from the forward end of the frame to the rear of the frame such that the spacing between rear end portions of the rearwardly converging blades is adjustable inwardly and outwardly relative the axis; and

a wheel rotatably supported in the frame for compressing the dirt generally moved into and over the trench by the pair of rearwardly converging blades.

4. The device of claim 3 wherein the frame includes brackets for attaching the forward end of the frame to a towing vehicle.

5. The device of claim 3 further includes a compression spring connecting the wheel to the frame for urging the wheel toward the trench.

6. The device of claim 3 further comprising:

a second pair of rearwardly converging blades supported by the frame rearwardly of the wheel to move dirt that was forced out of the trench by the wheel back into the trench.

7. The device of claim 6, wherein the second pair of rearwardly converging blades is adjustably supported on the frame on either side of an axis that extends from the forward end of the frame to the rear of the frame such that the spacing between rear end portions of the second pair of rearwardly converging blades is adjustable inwardly and outwardly relative the axis.
