Abstract
A twin discharge conveyor mounted on a spreader truck is shown including two parallel mounted conveying mechanisms such as augers, belt conveyors and chain conveyors contained within a conveyor trough that is mounted laterally on a truck chassis adjacent the front end of a frame mounted material storage container. The conveying mechanisms are independently controlled by separate hydraulic motors so that material can be discharged to the left and to the right of the truck simultaneously and in varying amounts.
Claims19
A material spreader mounted on a truck having a chassis, said material spreader comprising:
- a trough mounted laterally on the chassis of the truck, and
- at least two conveying mechanisms mounted within said trough, each of said conveying mechanisms being independently driven to rotate in a desired direction and at a desired speed, wherein
- each of said at least two conveying mechanisms is adapted to be driven in a first direction to convey material to one side of the chassis outboard of the chassis, and in a second direction to convey material to the opposite outboard side of the chassis.
A method of distributing material from a truck mounted material storage container, the truck including a longitudinal conveyor for moving the material to a laterally mounted trough mounted on the chassis of the truck having at least two lateral conveyors, said method comprising:
- moving material from said material storage container along said longitudinal conveyor into said trough, and independently controlling the rate of movement of said at least two lateral conveyors to distribute the material to opposite sides of said trough in a desired ratio, wherein
- each of said at least two lateral conveyors is adapted to be driven in a first direction to convey material to one side of the chassis outboard of the chassis and in a second direction to convey material to the opposite outboard side of the chassis.
A device for distributing material from a truck having a chassis and a material storage container mounted on the chassis comprising:
- means for moving material from said material storage container in a longitudinal direction relative to said material storage container;
- means for moving a first portion of said material in a first lateral direction relative to said material storage container and to one side of the chassis outboard of the chassis and depositing said first portion of said material on a first distributing means;
- and
- means for moving a second portion of said material in a second lateral direction different from said first lateral direction relative to said material storage container and to the opposite outboard side of the chassis and depositing said second portion of said material on a second distributing means, wherein
- said means for moving a first portion of said material in a first lateral direction is also adapted to move said first portion of said material in said second lateral direction, and said means for moving a second portion of said material in a second lateral direction is also adapted to move said second portion of said material in said first lateral direction.
