Material handling conveyor vehicle

摘要

Material handling solutions for a mobile conveyor vehicle are provided. In one aspect, a vehicle having an infeed and output conveyor is provided, one of the conveyors being mounted non-rotatably to the vehicle and positioned by rotation-in-place of the vehicle via four wheel steering. In another aspect, a dust control cover for a telescoping conveyor is provided, having a pair of flexible flaps which are parted by a plough-shaped chute which travels through a gap between the flaps and delivers material to the lower conveyor section. In another aspect, a hydraulic fluid transmission system for a mobile conveyor vehicle is provided which makes use of at least one hollow structural element to route the hydraulic fluid. The structural member may radiate heat from the fluid for example to melt snow on the vehicle structure.

主权项

1. A mobile conveyor vehicle for transporting material, comprising:
a chassis; a first conveyor system mounted to the chassis and non-rotatable horizontally relative to the chassis; a second conveyor system mounted to the chassis and rotatable relative to the chassis in the horizontal direction, the second conveyor system cooperating with the first conveyor system to transport the material; a steerable, powered drive system mounted to and supporting the chassis and configured for both transporting the vehicle and rotating the vehicle, wherein rotation of the vehicle causes corresponding rotation of the first conveyor system for position control thereof, and wherein the powered drive system comprises a plurality of independently steered and driven wheels; a plurality of pivotable support arms extending from the chassis, wherein each of the wheels is located on a respective one of the support arms; a wheel assembly pivotably mounted on one of the support arms and comprising one of said wheels; and a hydraulic cylinder mounted on said one of the support arms and coupled to the wheel assembly for pivoting of the wheel assembly to facilitate steering.
