Backfilling apparatus with dual telescopically positionable material dispensers
First Claim
1. A vehicle for transport and placement of fill material, comprising:
- a hopper, said hopper connected to-a central portion of a chassis of said vehicle at an attachment point, said central portion located between a front end and rear end of said chassis;
a first conveyor having a first moving surface, said first conveyor extending from a first end engaged to said chassis, toward a distal end;
a second conveyor having a second moving surface, said second conveyor extending from a first end engaged to said chassis, to a distal end;
a first discharge positioned to communicate a flow of said fill material in said hopper, onto-said first end of said first conveyor;
a second discharge positioned to communicate a flow of said fill material in said hopper, onto said first end of said second conveyor;
means for a tilting said hopper about said attachment point between a rearward angle substantially toward said rear end of said chassis and a forward angle substantially toward said front end of said chassis, said tilting thereby providing a means for adjusting the center of gravity of said vehicle;
one of said distal ends of said first and said second conveyor being positionable a distance from said chassis further than the other of said first and second conveyor; and
whereby said fill material deposited upon said first conveyor and said second conveyor, is depositable on or adjacent to a target position in two independent streams of said fill material, each of which communicates in a separate respective volume of said fill material from said hopper to said target position.

Abstract
A vehicle for transport and placement of fill material in trenches and for backfilling. The vehicle features a tiltable hopper connected to a central portion of a chassis which may be tilted to adjust the vehicle'"'"'s center of gravity. Two conveyors deposit two independent volumes of fill material on or adjacent to a target through the positioning of one conveyor a distance from the hopper further than the other. The speed of the conveyors or the volume of fill material placed thereon may be varied to vary each respective discharged volume of material from each conveyor. The conveyors and hopper may be engaged to the base of the vehicle on a chassis that is rotatable on the base and fluid dispensers may be positioned over each conveyor to dampen the fill material.
