Abstract

A skid steer rolling compactor attachment may include a universal attachment plate configured to attach to the skid steer. A boom includes a first end coupled to the attachment plate via a pivot hinge and a lift hinge. A hydraulic lift cylinder is coupled to the attachment plate and the boom in order to move the boom about the lift hinge, and a hydraulic pivot cylinder is coupled to the attachment plate and the boom in order to move the boom about the pivot hinge. A roller is attached to a second end of the boom via a tilt hinge and a twist hinge. A hydraulic tilt cylinder is coupled to the roller and the boom in order to move the roller about the tilt hinge, and a hydraulic twist cylinder is coupled to the roller and the boom in order to move the roller about the twist hinge.

Claims

1. A rolling compactor attachment comprising:

an attachment plate configured to attach to a host vehicle;

a boom having a first end coupled to the attachment plate via a pivot hinge and a lift hinge;

a lift cylinder coupled to the attachment plate and the boom and configured to move the boom about the lift hinge;

a pivot cylinder coupled to the attachment plate and the boom and configured to move the boom about the pivot hinge;

a roller attached to a second end of the boom via a tilt hinge and a twist hinge; and

a twist cylinder coupled to the roller and the boom and configured to move the roller about the twist hinge.

2. The rolling compactor attachment according to claim 1 wherein the boom is in the form of a hollow tube configured to allow hydraulic lines to run through an interior of the boom.

3. The rolling compactor at according to claim 1 wherein the attachment plate is oriented at an angle from vertical.

4. The rolling compactor attachment of claim 3 wherein the attachment is oriented at an angle 10 degrees forward from vertical.

5. The rolling compactor attachment of claim 1 wherein at least one of the lift cylinder, the pivot cylinder, and the twist cylinder is in the form of a hydraulic cylinder.

6. The rolling compactor attachment of claim 1 further comprising a frame attached to the boom and configured to support the roller.

7. The skid steer rolling compactor attachment according to claim 6 further comprising at least one adjustable scraper mounted to the frame on at least one side of the roller and extending a length of the roller.

8. The rolling compactor attachment according to claim 1 further comprising at least one side plate mounted to at least one of a left end and a right end of the roller.

9. The rolling compactor attachment according to claim 1 wherein each one of the cylinders of the rolling compactor attachment are configured to be remotely controlled from within a skid steer.

10. The roiling compactor attachment according to claim 1 wherein at least one of the lift cylinder, the pivot cylinder, and the twist cylinder is an electronic actuator.

11. A rolling compactor attachment device comprising:

an attachment plate configured to attach to a host vehicle;

a boom coupled to the attachment plate by way of a pivot hinge and a lift hinge;

a roller attached to an end of the boom opposite the attachment plate by way of a tilt hinge and a twist hinge, the roller being supported by a frame;

a pivot acuator coupled to the attachment plate and the boom to horizontally transition the boom about the pivot hinge; and

a lift acuator coupled to the attachment plate and the boom to vertically transition the boom about the lift hinge.

12. The rolling compactor attachment device of claim 11 wherein the boom comprises a plurality of sidewalls surrounding an interior configured to receive hydraulic lines.

13. The rolling compactor attachment device of claim 11 wherein the attachment plate is oriented at an angle.

14. The rolling compactor attachment device of claim 13 wherein the attachment plate is oriented 10 degrees forward of vertical.

15. The rolling compactor attachment device of claim 11 wherein at least one of the hydraulic actuator and the pivot actuator is a hydraulic cylinder that includes a counter balance valve.

16. The rolling compactor attachment device of claim 11 wherein the actuators are configured to be remotely and individually controlled from within the host vehicle.

20. The rolling compactor attachment device of claim 11 wherein at least one of the lift actuator and the pivot actuator is an electronic actuator.

17. A method of manufacturing a rolling compactor attachment device comprising:

pivotally coupling a first end of a boom to an attachment plate via a pivot hinge and a lift hinge;

pivotally coupling a roller to a second end of the boom via a tilt hinge and a twist hinge;

disposing a lift cylinder between the attachment plate and the boom to transition the boom vertically about the lift hinge;

disposing a pivot cylinder between the attachment plate and the boom to transition the boom horizontally about the pivot hinge; and

disposing a twist cylinder between the boom and the roller to pivot the roller about the twist hinge.

18. The method of claim 17 wherein at least one of the lift cylinder, the pivot cylinder, and the twist cylinder is in the form of a hydraulic cylinder.

19. The method of claim 17 further comprising orienting the attachment plate at an angle 10 degrees forward from vertical.
