Trench filling device
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.
This invention relates to a device for filling a trench with the dirt previously removed to form the trench.
BRIEF DESCRIPTION OF THE DRAWINGS
Referring to the drawings in detail, and particularly
As shown in
As shown in
The forward end 42 of each of the rearwardly converging scraper blades 16 is suitably secured to the forward end 18 of the respective side of the frame 14 by a suitable bracket 44 as shown in
As indicated in
As shown in
An alternate embodiment 10a is shown schematically in
It will be understood by those skilled in the art that the blades 16 and 64 in
The purpose of device 10 is to move the dirt 72 (
The dirt moved by the scraper blades 16 will extend above the level of the ground on each side of the trench and the horizontally extending scraper blade 20 will temporarily level that dirt, before it is contacted and somewhat compressed or compacted by the roller 22. The level of the dirt behind the device 10 will be a short distance above the ground on each side of the trench, allowing for the dirt to settle in the trench and eventually end up with a relatively level surface where the trench had been.
The modified device 10A shown in
Changes may be made in the combination and arrangement of parts or elements as here to fore set forth in the specification and shown in the drawing without departing from the spirit and scope of the invention as defined in the following claims.
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.
