Abstract

The present invention is a flexible skid steer road widening and shouldering attachment device with an adjustable spreader system which gives the operator precise control over the placement of debris.

Claims

1. A highly resilient skid steer attachment for a skid steer comprised of:

a support frame supported by at least two support brackets having a first end, a second end, a first side, and a second side opposite said first side;

a hopper having four a plurality of angled walls for receiving debris at an angle of deflection which minimizes the impact of debris on a conveyer belt;

wherein one of said four angled walls is vertical relative to a horizontal plane;

wherein three a plurality of said four angled walls further include a vertical deflection component oriented vertically for directing debris downward;

a conveyor system comprised of a conveyer belt and a pulley, said pulley being at least two inches wider than said conveyer belt;

at least one hydraulic power system for powering said conveyor system;

a spreader system;

a plurality of tandem casters rotatably attached at a said first end of said support frame, said plurality of tandem casters comprised of steel polyurethane plastic;

at least one contact roller rotatably attached to said first end of said support frame; and

a universal mounting plate attached at a said second end of the support frame in a manner that allows said mounting plate to be engaged by a skid steer.

2. The highly resilient skid steer attachment for a skid steer of claim 1 further including a second spreader system.

3. The highly resilient skid steer attachment for a skid steer of claim 1 wherein said angled walls have varying different slopes ranging from 100 to 170 degrees as measured from a point on a horizontal plane.

4. The highly resilient skid steer attachment for a skid steer of claim 1 wherein said angled walls have angles ranges ranging from 90 to 170 degrees relative to a horizontal plane.

5. The highly resilient skid steer attachment for a skid steer of claim 1 wherein at least one of said angle wails is vertical relative to a horizontal plane.

6. The highly resilient skid steer attachment for a skid steer of claim 1 further including a width ranging from 100 inches to 170 inches, a length ranging from 75 inches to 175 inches, and a height ranging from 28 inches to 58 inches.

7. The highly resilient skid steer attachment for a skid steer of claim 1 wherein said spreader system is comprised of two walls formed at a right angle.

8. The apparatus skid steer attachment for a skid steer of claim 1 which further includes a spreader system angular adjustment for adjusting the slope of said spreader system when extended.

9. The apparatus skid steer attachment for a skid steer of claim 1 wherein said spreader system is capable of creating shoulders ranging from 0 to 7 feet wide.

10. A skid steer attachment device comprising:

a support frame;

a hopper with a plurality of angled walls, wherein at least one of said plurality of angled walls is vertical relative to a horizontal plane, and wherein at least one of said plurality of angled walls further includes a vertical deflection component configured to direct debris vertically downward;

a conveyor system including a conveyer belt and at least one pulley wherein the at least one pulley is wider than said conveyer belt;

a pulley that is at least 2 inches wider than the conveyer belt and configured to prevent the conveyer belt from moving off an edge of the pulley;

at least one system for powering said conveyor system;

a spreader system comprising a first wall extending at a first angle from the support frame and a second wall extending at a second angle from the first wall;

a plurality of tandem casters rotatably attached at a first end of said support frame;

at least one contact roller rotatably attached to said first end of said support frame configured for engagement with at least one rear wheel of a vehicle; and

a universal mounting plate attached at a second end of the support frame configured for attachment to a skid steer.

11. The skid steer attachment device of claim 10 wherein said plurality of angled walls has angles ranging from 90 to 170 degrees relative to a horizontal plane.

12. The skid steer attachment device of claim 11 wherein the spreading system includes a an adjustable slope and an extendable spreader for angular adjustment configured to adjust the slope of said spreader when extended.

13. The skid steer attachment device of claim 12 further including a width ranging from 100 inches to 170 inches, a length ranging from 75 inches to 175 inches, and a height ranging from 28 inches to 58 inches.

14. The skid steer attachment device of claim 10 wherein said at least one system for powering said conveyor system comprises a hydraulic system.

15. A highly resilient skid steer attachment for a skid steer comprised of:

a support frame supported by at least two support brackets;
