US 4,022,386 A · Material spreader for trucks

Abstract

A material spreader usable at the rear of dump trucks for distributing sand, salt, gravel, asphalt and the like, utilizes a dispensing means to drop material downwardly from the rear of the truck bin. A conveyor is positioned below the dispensing means and has a hopper to receive dropping material. The conveyor moves the material laterally to the right or left side of the truck. One or more flat, generally rectangular shields are swingably mounted to the hopper to swing between an operating position, wherein the shield overlies the hopper, intercepts falling material, and serves as a ramp in guiding it rearwardly and downwardly over the hopper to drop it behind the truck, and a storage position, wherein the shield is clear of the hopper so that material from the dispensing means moves freely into the hopper so as to be conveyed laterally by the conveyor. Latches are provided to retain the shields in storage and blocking positions. A splash panel is provided forwardly of the conveyor to intercept snow, mud, and the like which would otherwise be splashed into the conveyor by the moving truck.

Dependent claims

A material spreader usable with a dump truck having a material carrying bin with a pair of lateral sidewalls to dispense material from the bin and onto a roadway, comprising:

a material moving apparatus attachable to the truck and mountable adjacent the rear of the bin, said apparatus including dispensing means positionable to receive material from the bin and to release the material in a rearward and downward direction to define a flow of material extending substantially between the lateral sidewalls of the bin, and further including an open-ended conveyor positioned below said dispensing means to receive material from said dispensing means and capable of moving material received from said dispensing means laterally relative to the truck and discharging the material laterally from the open-ended conveyor and onto the roadway;
and
ramp means movably mounted to said material moving apparatus and movable between a storage position permitting unobstructed flow of material from said dispensing means to said conveyor, and an operating position overlying said conveyor, wherein said ramp means intercepts material released from said dispensing means, said ramp means when in operating position being angled transversely to said rearward and downward direction of flow rearwardly and downwardly from said dispensing means to rearwardly deflect and distribute the material.
