Abstract

An adaptable material-spreading vehicle includes in combination a truck body frame, a rear-mounted engine on the frame above the rear wheels, a forward cab, a removable hopper positioned between the cab and the rear-mounted engine, and a conveyor running from beneath the hopper directly through the cab to a material spreader mounted forward of the cab in view of the operator, 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, with the cab being provided with sealable conveyor ports aligned fore and aft through which the cab-carried conveyor section is passed. In a preferred embodiment, the conveyor runs the entire length of the bottom of the hopper trough 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 the frame over the rear wheels and operably connected to drive the rear wheels;

a cab forwardly mounted to said frame, said cab having a longitudinally extending channel therethrough and having front and back walls each having a port adjacent an end of said channel;

a removably mounted hopper between said cab and said engine;

a conveyor positioned through said cab and extending both beneath said hopper and ahead of said cab;

a spreader attached to the end of said conveyor ahead of said cab, said spreader being visible from said cab; and

means for driving said conveyor and spreader.

2. The vehicle of 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 to abut said one section, and means for coupling said sections together.

3. The vehicle of claim 1 wherein said conveyor is at least partially exposed in said cab.

4. The vehicle of claim 1, whereby 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.

5. The vehicle of claim 4 wherein said cover includes a trap door.

6. The vehicle of claim 4 wherein at least a portion of said cover is optically transparent.

7. The vehicle of 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.

8. The vehicle of claim 7 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.

9. The vehicle of claim 8 and further including quick disconnect couplings between said control means and said hydraulic motor.

10. The vehicle of 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.

11. The vehicle of 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.
