Abstract

An adaptable material-spreading vehicle includes in combination a truck body frame, an engine mounted on the frame, a cab mounted in a forwardly positioned cab region, a removable hopper positioned behind the cab region, and a conveyor running from beneath the hopper directly through the cab region to a forwardly mounted material spreader with the hopper and conveyor being removably mounted to the truck frame, such that the material spreader vehicle can be converted to some other use. In one embodiment, the cab is provided with a central channel through the floor to accommodate the section of the conveyor passing through the cab region, with the cab being provided with sealable conveyor ports aligned fore and aft through which the cab-carrier conveyor section is passed. In a preferred embodiment, the conveyor runs the entire length of the bottom of the hopper through such that material is initially removed from the rear of the hopper, thereby providing that the majority of the weight of the dispensed material is as far forward as possible.

Claims

1. An adaptable material spreading vehicle comprising:

a vehicle body having a frame and front and rear wheels;

an engine mounted to said frame operably connected to said wheels;

an operator cab mounted to said frame at a forwardly positioned cab region centrally disposed between the wheels;

a removable hopper mounted to said frame rearward of said cab region;

a conveyor positioned in a channel passing through said cab region and extending from beneath said hopper to the forward end of said vehicle body, and wherein said channel passes through said cab region to permit visual inspection of dispensed material carried by said conveyor from said operator cab; and

a spreader attached to the end of said conveyor mounted to the forward end of said vehicle body and means for driving said conveyor and spreader.

2. The vehicle according to claim 1 wherein said engine is mounted over the rear wheels of said vehicle body.

3. The vehicle according to claim 1, wherein said spreader is mounted ahead of said cab such that said spreader is visible from said cab.

4. The vehicle according to claim 1 wherein said cab has a front face positioned forward of an operator position within the cab;

at least part of said spreader being mounted substantially rearward of said front face such that at least some of said spreader is mounted within said cab region.

5. The vehicle according to claim 4 further including a bumper mounted directly forward of said front face.

6. The vehicle according to claim 1 wherein said conveyor includes two mateable sections, one carried by the hopper with a portion thereof extending forwardly of said hopper, the other section being positioned through said cab region to abut said one section, and means for coupling said sections together.

7. The vehicle according to claim 1 wherein said cab region has a longitudinally extending channel therethrough for said conveyor with front and back walls each having a port adjacent an end of said channel.

8. The vehicle according to claim 7 wherein said conveyor is at least partially exposed in said cab.

9. The vehicle according to claim 7 wherein said cab includes a cover over at least a portion of said channel and said conveyor whereby said conveyor is at least partially covered with said cab.

10. The vehicle according to claim 9 wherein said cover includes a trap door.

11. The vehicle according to claim 9 wherein at least a portion of said cover is optically transparent.

12. The vehicle according to claim 1 wherein said drive means includes a hydraulic motor mounted to said conveyor, and further including a hydraulic pump driven by said engine, the output of said pump having means for operably coupling hydraulic fluid to said hydraulic motor.

13. The vehicle according to claim 12 wherein said cab includes hydraulic fluid control means and wherein said hydraulic fluid coupling means includes hydraulic fluid lines from said pump to said control means and from said control means to said hydraulic motor.

14. The vehicle according to claim 13 and further including quick disconnect couplings between said control means and said hydraulic motor.

15. The vehicle according to claim 1 and further including members extending forward of said cab and surrounding and projecting in front of said spreader, said members adapted to receive additional apparatus at the forward ends thereof.

16. The vehicle according to claim 1 wherein said conveyor extends the entire bottom length of said hopper, thereby to initially remove hopper-carried material from the back portion of said hopper during conveyor operation.

17. The vehicle according to claim 1 wherein said cab occupies only a portion of said cab region to one side of said conveyor.

18. An adaptable material spreading vehicle, comprising:

a vehicle body having a frame and front and rear wheels;

an engine mounted to said frame operably connected to said wheels;

an operator cab mounted to said frame at a forwardly positioned cab region centrally disposed between the wheels, said cab region having a longitudinally extending channel therethrough and front and back walls each having a port adjacent an end of said channel;

a removable hopper mounted rearward of said cab region;

a conveyor positioned in said channel passing through said cab region and extending from beneath said hopper to the forward end of said vehicle body and wherein said conveyor is least partially exposed in said cab; and

a spreader attached to the end of said conveyor mounted to the forward end of said vehicle body and means for driving said conveyor and spreader.
