Abstract

A self propelled vehicle for transport and placement of an onboard supply of fill material in an onboard hopper. The hopper is connected to said vehicle at a point operatively positioned to discharge fill material placed therein on a conveyor belt mounted to a support structure. The fill material is deposited on the conveyor at a receiving and discharged at the distal end of the conveyor either directly or via a flow director attached to the distal end attached thereto. The flow director bifurcates the stream of fill material allowing the operator to place more or less of the fill in two streams using a plurality of independently adjustable channeling ramps. The hopper is optionally adjustable from an angle normal to the vehicle to allow for adjustment in the vehicle center of gravity on grades. The flow director can also be configured for attachment to existing conveyors to increase their utility or used as part of the entire self propelled device in a single unit. Optionally, the distal end of the conveyor may be elevated or lowered for proper positioning.

Claims

1. A vehicle for transport and placement of an on board supply of fill material, comprising:

a hopper connected to a chassis of said vehicle at an attachment point, said hopper having discharge aperture operatively positioned to discharge a stream of fill material contained in said hopper, onto a conveyor;

said conveyor having a support structure attached to said chassis, a conveyor belt, a receiving end adjacent to said hopper, a distal end opposite said receiving end, a means for powering rotation of said belt; and

whereby said stream of fill material transported by said conveyor from said hopper may be adjustably deposited onto a selected target position by repositioning said distal end.

2. The vehicle for transport and placement of an on board supply of fill material of claim 1 wherein said conveyor is telescopic.

3. The vehicle for transport and placement of an on board supply of fill material of claim 1 further comprising:

means for adjustment of the center of gravity of said vehicle.

4. The vehicle for transport and placement of an on board supply of fill material of claim 2 further comprising:

means for adjustment of the center of gravity of said vehicle.

5. The vehicle for transport and placement of an on board supply of fill material of claim 3 wherein said means for adjustment of the center of gravity of said vehicle comprises:

said hopper rotationally attached at said attachment point to said vehicle using an axil; and

means for rotation of said fill hopper on said axil whereby said fill hopper may be tilted by remote control to thereby change the center of gravity of the fill hopper and the attached vehicle.

6. The vehicle for transport and placement of an on board supply of fill material of claim 4 wherein said means for adjustment of the center of gravity of said vehicle comprises:

said hopper rotationally attached at said attachment point to said vehicle using an axil; and

means for rotation of said fill hopper on said axil whereby said fill hopper may be tilted by remote control to thereby change the center of gravity of the fill hopper and the attached vehicle.

13. The vehicle for transport and placement of an on board supply of fill material of claim 1 additionally comprising:

means for adjustment of the elevation of the distal end.

14. The vehicle for transport and placement of an on board supply of fill material of claim 2 additionally comprising:

means for adjustment of the elevation of the distal end.

15. The vehicle for transport and placement of an on board supply of fill material of claim 3 additionally comprising:

means for adjustment of the elevation of the distal end.

16. The vehicle for transport and placement of an on board supply of fill material of claim 2 additionally comprising:

means for adjustment of the elevation of the distal end.

17. The vehicle for transport and placement of an on board supply of fill material of claim 5 additionally comprising:

means for adjustment of the elevation of the distal end.

18. The vehicle for transport and placement of an on board supply of fill material of claim 6 additionally comprising:

means for adjustment of the elevation of the distal end.

7. A vehicle for transport and placement of an on board supply of fill material, comprising:

a hopper connected to a chassis of said vehicle at an attachment point, said hopper having discharge aperture operatively positioned to discharge a stream of fill material contained in said hopper, onto a conveyor;

said conveyor having a support structure attached to said chassis, a conveyor belt, a receiving end adjacent to said hopper, a distal end opposite said receiving end, a means for powering rotation of said belt; and

means for bifurcating said stream of fill material communicated to said distal end of said conveyor from said receiving end into two separated material streams.

8. The vehicle for transport and placement of an on board supply of fill material of claim 7 wherein said conveyor is telescopic.

9. The vehicle for transport and placement of an on board supply of fill material of claim 7 further comprising:

means for adjustment of the center of gravity of said vehicle.

10. The vehicle for transport and placement of an on board supply of fill material of claim 8 further comprising:

means for adjustment of the center of gravity of said vehicle.

11. The vehicle for transport and placement of an on board supply of fill material of claim 9 wherein said means for adjustment of the center of gravity of said vehicle comprises:

said hopper rotationally attached at said attachment point to said vehicle using an axil; and

means for rotation of said fill hopper on said axil whereby said fill hopper may be tilted by remote control to thereby change the center of gravity of the fill hopper and the attached vehicle.

12. The vehicle for transport and placement of an on board supply of fill material of claim 10 wherein said means for adjustment of the center of gravity of said vehicle comprises:

said hopper rotationally attached at said attachment point to said vehicle using an axil; and

means for rotation of said fill hopper on said axil whereby said fill hopper may be tilted by remote control to thereby change the center of gravity of the fill hopper and the attached vehicle.

19. The vehicle for transport and placement of an on board supply of fill material of claim 7 additionally comprising:

means for adjustment of the elevation of the distal end.

20. The vehicle for transport and placement of an on board supply of fill material of claim 8 additionally comprising:

means for adjustment of the elevation of the distal end.

22. The vehicle for transport and placement of an on board supply of fill material of claim 9 additionally comprising:

means for adjustment of the elevation of the distal end.
