US 8,403,594 B2 · Aggregate-spreading device

Abstract

An aggregate-spreading device is disclosed for widening roads, filling trenches, spreading any kind of road construction material, and creating shoulders on the side of roads at a controllable, quick, and steady pace. The aggregate-spreading device may be controlled by electronic motors and electronic actuators. The aggregate-spreading device is equipped with a skeletal frame, either a first and a second adjustable spreader assembly attached on opposing ends of the skeletal frame, or a single spreader assembly for allowing an operator precise control over placement of an aggregate. The aggregate may be supplied to the first or second adjustable spreader assemblies by adjusting the rotation of a reversible conveyor system. The skeletal frame simplifies manufacturing of the aggregate-spreading device and allows for easy repairs and maintenance. The electronic motors and electronic actuators eliminate the need for hydraulics, allowing an operator to control the device from a remote location with a controller.

4 more elements

An aggregate-spreading device comprising:

a skeletal frame with a plurality of integrated roller mounts;
a hopper connected to the skeletal frame, the hopper configured to receive an aggregate from a proximate vehicle;
a single hopper support bar configured to support the hopper above the skeletal frame at an adjustable distance;
a conveyor system attached to the skeletal frame including:
a) a conveyor drive unit with a plurality of threaded rods engaging the skeletal frame, the conveyor drive unit including a plurality of T shaped extensions with ends in contact with the conveyor, the T shaped extensions converging on a single roller with ends;
b) a bearing joined to each one of the ends of the single roller;
c) a conveyer with an adjustable speed and a reversible rotation configured to receive the aggregate from the hopper, a plurality of rollers attached to the integrated roller mounts;
and
d) a spreader assembly attached to an end of the skeletal including:
i. a controllable piston configured to extend and retract the spreader assembly from the skeletal frame wherein the spreader assembly receives the aggregate from the conveyor and spreads the aggregate evenly.
