Abstract

An auxiliary conveying apparatus for receiving and conveying mined material from a bridge conveyor that is pivotally attached to the discharge end of a mobile articulated conveyor. The apparatus includes an endless belt conveyor that is disposed at an angle between the first and second stationary conveyors that intersect at right angles to one another. First and second guide rails are provided to guide the bridge conveyor at a predetermined height along the first and second stationary conveyors. Third and fourth guide rails are provided to guide the discharge end of the bridge conveyor in a curvilinear path at a second predetermined height above the endless belt conveyor. Hinged transition guides are attached to the ends of the fourth guide rail to create a ramp between the first and fourth guide rails while a fixed guide rail section creates a ramp between the first and third guide rails. A four-wheeled dolly is pivotally attached to the discharge end of the bridge conveyor and is adapted to support the discharge end thereof along the four guide rails. A two-wheeled dolly, adapted to ride on the second guide rail, is pivotally attached to the discharge end of the mobile articulated conveyor. Cam shaped members are provide on the two-wheeled dolly to raise the hinged transition rail above the two-wheeled dolly so that it may freely pass thereunder and thus remain on second guide rail.
