Abstract

A skid steer rolling compactor attachment may include a universal attachment plate configured to attach to the skid steer. A boom extending from the attachment plate may pivot about at least one articulating hinge attached to the boom. The boom may be configured to move a roller to compact a ground surface as the skid steer travels in a forward direction. In order to prevent roll-overs on uneven surfaces, the skid steer may be operated on a level surface and articulate the boom such that the roller contacts the ground parallel to the direction of travel. The skid steer may then compact inclined surfaces while travelling on level surfaces thus improving worker safety.

Claims

1. A skid steer rolling compactor attachment comprising:

an attachment plate configured to attach to the skid steer;

a boom configured to attach to the attachment plate;

a pivot hinge disposed between the attachment plate and the boom and configured to allow the boom to pivot about a vertical axis;

a lift hinge disposed between the attachment plate and the boom and configured to allow the boom to lift about a horizontal axis;

a roller attached to the boom opposite the attachment plate configured to compact a ground surface;

a tilt hinge joining the roller to the boom configured to tilt the roller with respect to a level road; and

a twist hinge configured to twist the roller about a vertical axis.

2. The skid steer rolling compactor attachment according to claim 1, further comprising:

an adjustable scraper extending a length of the roller configured to scrape a debris off of the roller as the roller revolves about a bearing.

3. The skid steer rolling compactor attachment according to claim 1, further comprising a hydraulic lift cylinder attached to the attachment plate and the boom configured to lift and lower the boom about the lift hinge.

4. The skid steer rolling compactor attachment according to claim 1, further comprising:

a frame attached to the boom supporting the roller; and

a hydraulic twist cylinder attached to the frame and the boom configured to twist the roller about the twist hinge.

5. The skid steer rolling compactor attachment according to claim 1, further comprising:

a frame attached to the boom supporting the roller; and

a hydraulic tilt cylinder attached to the frame and the boom configured to tilt the roller about the tilt hinge.

6. The skid steer rolling compactor attachment according to claim 1, further comprising a frame attached to the boom supporting the roller, wherein the frame is coupled to a central axis of the roller by way of at least one bearing.

7. The skid steer rolling compactor attachment according to claim 1, further comprising a pivot lift cylinder attached to the attachment plate and the boom configured to pivot the boom about the pivot hinge.

8. The skid steer rolling compactor attachment according to claim 1, wherein the lift hinge is configured to allow the boom to lift about the horizontal axis between a fully raised position and a fully lowered position, wherein the fully raised position places the roller above the skid steer, and wherein the fully lowered position places the roller below the skid steer.

9. A skid steer rolling compactor attachment comprising:

an attachment plate configured to attach to the skid steer;

a pivot hinge attached to the attachment plate;

a lift hinge attached to the attachment plate;

a boom attached to the attachment plate by way of the pivot hinge and the lift hinge, wherein the boom is configured to move about the pivot hinge in a horizontal direction, and wherein the boom is configured to move about the lift hinge in a vertical direction;

a twist hinge attached to the boom opposite the attachment plate;

a tilt hinge attached to the boom opposite the attachment plate;

a roller attached to the twist hinge and configured to twist in a horizontal direction about the twist hinge and the roller attached to the tilt hinge and configured to tilt in a vertical direction about the tilt hinge; and

wherein the roller is configured to compact a ground surface.

10. The skid steer rolling compactor attachment according to claim 9, further comprising:

a frame attached to the boom and configured to support the roller on a bearing; and

an adjustable scraper mounted to the frame and extending a length of the roller configured to scrape a debris off of the roller as the roller revolves about the bearing.

11. The skid steer rolling compactor attachment according to claim 9, further comprising:

a hydraulic lift cylinder attached to the attachment plate and the boom configured to lift and lower the boom about the lift hinge;

a hydraulic twist cylinder attached to the frame and the boom configured to twist the roller about the twist hinge;

a hydraulic tilt cylinder attached to the frame and the boom configured to tilt the roller about the tilt hinge; and

a hydraulic pivot cylinder attached to the attachment plate and the boom configured to pivot the boom about the pivot hinge.

12. The skid steer rolling compactor attachment according to claim 10, further comprising:

a pair of side plates attached to the frame surrounding the roller; and

a guide attached to each one of the side plates.

13. The skid steer rolling compactor attachment according to claim 11, wherein each one of the hydraulic cylinders of the rolling compactor attachment are configured to be remotely and hydraulically controlled from within a skid steer.

14. The skid steer rolling compactor attachment according to claim 10, wherein the frame is attached to a central axis of the roller.

15. A method of operating a skid steer comprising:

attaching a mounting plate to a skid steer;

attaching a boom to the mounting plate by way of a pivot hinge and a lift hinge;

attaching a frame to the boom opposite the mounting plate;

attaching a roller to the frame;

articulating the roller to a side of the skid steer;

lowering the roller to contact a sloped surface;

maintaining the skid steer on a level ground; and

compacting the inclined sloped as the skid steer is driven on the level ground.

16. The method of operating a skid steer according to claim 15, further comprising pivoting the boom about the pivot hinge with a pivot cylinder operated from within the skid steer.

17. The method of operating a skid steer according to claim 15, further comprising lifting the boom about the lift hinge with a lift cylinder operated from within the skid steer.

18. The method of operating a skid steer according to claim 15, further comprising twisting the roller about a twist hinge with a twist cylinder operated from within the skid steer.

19. The method of operating a skid steer according to claim 15, further comprising tilting the roller about a tilt hinge with a tilt cylinder operated from within the skid steer.

20. The method of operating a skid steer according to claim 15, wherein attaching a roller to the frame comprises attaching the frame to a central axis of the roller.
