Abstract

A conveyor system includes a plurality of crawler members, a frame supported via the crawler members, a skid pad moveable relative to the frame to raise and lower the frame relative to a ground surface, and an intake structure supported by the frame. The intake structure includes a first conveyor. The conveyor system further includes a discharge boom supported by the frame. The discharge boom includes a second conveyor.

First claim

What is claimed is:

1. A conveyor system comprising:
a plurality of crawler members configured to move along a ground surface;
a frame supported by the crawler members and extending along a longitudinal axis;
a skid pad moveable relative to the frame to raise and lower the frame relative to a ground surface;
an intake structure supported by the frame, the intake structure including a first conveyor; and
a discharge boom supported by the frame, the discharge boom including a second conveyor, wherein the boom is configured to pivot 90 degrees from a horizontal position along the longitudinal axis to a vertical position relative to the longitudinal axis so as to extend vertically relative to the ground surface.

2. The conveyor system of claim 1 , wherein the discharge boom includes a first end pivotally coupled to the frame and a second, opposite end spaced from the frame.

3. The conveyor system of claim 2 , further comprising a boom mast coupled to the frame, and a hydraulic piston-cylinder assembly extending between the boom mast and the second end of the discharge boom.

4. The conveyor system of claim 2 , wherein the intake structure includes a first end and a second, opposite end, wherein the second end of the intake structure overlaps the first end of the discharge boom, such that material moving along the first conveyor is configured to drop from the second end of the intake structure and onto the second conveyor.

5. The conveyor system of claim 1 , wherein each of the first conveyor and the second conveyor includes a head drive shaft at one end of the first or second conveyor, a tail drive shaft at an opposite end of the first or second conveyor, a first chain disposed along one side of the first or second conveyor, a second chain disposed along an opposite side of the first or second conveyor, and a plurality of flights coupled between the first and second chains.

6. The conveyor system of claim 1 , wherein each of the crawler members is rotatable relative to the frame.

7. The conveyor system of claim 6 , wherein each of the crawler members is rotatable at least 90 degrees relative to the frame.

8. The conveyor system of claim 6 , wherein the crawler members are independently rotatable relative to the frame.

9. The conveyor system of claim 1 , further comprising a control system configured to receive a signal remotely from an operator, wherein the control system is configured to operate at least one of the plurality of crawler members, the skid pad, the first conveyor, or the second conveyor.

10. The conveyor system of claim 1 , wherein the skid pad is movable between a retracted position and an extended position relative to the frame.

11. The conveyor system of claim 1 , wherein the crawler members include at least four crawler members each having a crawler track driven by a drive system, and wherein the skid pad is disposed adjacent one of the four crawler members.

12. The conveyor system of claim 1 , wherein the skid pad is a first skid pad, and further comprising a second skid pad movable relative to the frame to raise and lower the frame, wherein the plurality of crawler members are positioned between the first skid pad and the second skid pad.

13. A conveyor system comprising:
a plurality of crawler members;
a frame supported by the crawler members;
an intake structure supported by the frame, the intake structure including a first conveyor; and
a discharge boom supported by the frame, the discharge boom including a second conveyor;
wherein each of the crawler members is independently rotatable relative to the frame.

14. The conveyor system of claim 13 , wherein each of the crawler members is rotatable at least 90 degrees relative to the frame.

15. The conveyor system of claim 13 , wherein the discharge boom includes a first end pivotally coupled to the frame, and a second opposite end spaced from the frame.

16. The conveyor system of claim 15 , further comprising a boom mast coupled to the frame, and a hydraulic piston-cylinder assembly extending between the boom mast and the second end of the discharge boom.

17. The conveyor system of claim 15 , wherein the intake structure includes a first end and a second, opposite end, wherein the discharge boom includes a first end and a second, opposite end, and wherein the second end of the intake structure overlaps the first end of the discharge boom, such that material moving along the first conveyor is configured to drop from the second end of the intake structure and onto the second conveyor.

18. The conveyor system of claim 15 , wherein the conveyor system is configured to move along a ground surface, and wherein the discharge boom is pivotal at least 90 degrees relative to the frame.

19. The conveyor system of claim 13 , wherein each of the first conveyor and the second conveyor includes a head drive shaft at one end of the first or second conveyor, a tail drive shaft at an opposite end of the first or second conveyor, a first chain disposed along one side of the first or second conveyor, a second chain disposed along an opposite side of the first or second conveyor, and a plurality of flights coupled between the first and second chains.
