ABSTRACT:
A base member having ground traction devices is connected by an elevation device to a vehicle frame. The vehicle frame supports a feeder portion that includes a fixed storage hopper. A power source for operating the ground traction devices is positioned forwardly of the feeder portion. At the discharging end portion of the feeder portion a pair of scrolls positioned in a trough feed the loose mined material into a breaker unit and therefrom onto a conveyor underlying the vehicle. A movable hopper is positioned for reciprocal longitudinal movement relative to the storage hopper by operation of a pair of piston cylinder assemblies. The movable hopper includes a hinged tailgate operable to move between an open position for loading the vehicle and a closed position for feeding the material to the breaker unit. With the tailgate in the closed position, the movable hopper is advanced the length of the storage hopper forcing the material into the rotating path of the scrolls that feed the material to the breaker unit. To complete the feeding operation the tailgate is advanced the length of the movable hopper discharging the remaining material into the scroll-breaker unit. When the discharging operation is completed, the movable hopper and tailgate return to the receiving end portion of the storage hopper to receive the next load of material from a haulage unit.
