Combined dump truck and spreader apparatus
DCFirst Claim
1. A combined dump truck and spreader apparatus for selectively dumping and spreading materials, said apparatus comprising:
- a truck chassis;
a dump body for receiving and dispensing the materials, said body having a first and a second end and a first and a second side wall, said body being pivotally secured to said chassis about a pivotal axis;
hoist means extending between said body and said chassis for selectively pivoting said body about said pivotal axis;
a tailgate secured to said first end of said body for selectively permitting dumping of the materials therethrough when said body is pivoted about said pivotal axis;
drive means;
endless conveyor means trained over said drive means, said conveyor means being disposed at a bottom of said walls and within said body and extending between said first and second ends thereof for conveying the materials along said body;
spreader means cooperating with said conveyor means for spreading the materials;
said tailgate defining an opening which co-operates with said conveyor means for permitting the flow therethrough of the materials, the arrangement being such that selective spreading and dumping of the materials from said opening is permitted; and
said side walls curving downwardly and inwardly towards said conveyor means such that said dump body defines a substantially semi-elliptical cross sectional configuration for guiding and evenly deflecting all of the materials within said body towards said conveyor means along the entire length of said conveyor means.

Abstract
A combined dump truck and spreader apparatus is disclosed for selectively dumping and spreading materials. The apparatus includes a truck chassis and a body for receiving and dispensing the materials. The body has a first and a second end and a first and second curved side wall. The body is secured to the chassis and a tailgate is secured to the first end of the body. An auger arrangement is disposed within the body and extends between the first and second ends thereof for transporting the materials along the body. The tailgate defines an opening which co-operates with the auger arrangement for permitting the flow therethrough of the materials. The arrangement is such that selective spreading and dumping of the materials from the opening is permitted.
