Radial stacking conveyor system with feeder

A device for conveying a solid material into a radially-arranged stockpile, comprising:

• a trailer chassis, having, at a first end thereof, at least one wheeled axle and, at a second end thereof, means provided for attaching the trailer chassis to a tractor in a mobile condition and for fixed mounting in an operational condition;
• a turret, arranged near the first end of the trailer chassis on a top surface thereof for rotation about an axis normal thereto;
• a stacking conveyor, having an arm with at least a withdrawn length and an extended length with a first end thereof fixedly mounted to the turret near the first end of the trailer chassis;
• a stand-alone power unit for generating electrical and hydraulic power that is mounted to the trailer chassis between the feed system and the stacking conveyor;
• and
• a feed system, mounted to the trailer chassis and extending generally along the length thereof from the second end to the first end, to receive the solid material at the second end and transport the solid material to the stacking conveyor, the feed system comprising:
• a feed hopper mounted to the trailer chassis near the second end thereof;
• a first feed conveyor and a second feed conveyor that is an articulated conveyor, with an arm having first and second arm portions connected by an elbow joint, the arm movable between a folded or stowed condition for transport and an open or extended condition for operation;
• wherein, in the mobile condition, the second feed conveyor is in the folded condition and the turret rotates the stacking conveyor so that the stacking conveyor extends from the first end of the trailer chassis towards the second end of the trailer chassis, above the second feed conveyor with a second end of the stacking conveyor above the feed hopper.
