Abstract:
A transportable apparatus for unloading materials from a dump truck and directing the material onto a conveyor assembly, the apparatus comprising:an inclined ramp adapted to receive the dump truck driving thereon, the height of the inclined ramp increasing from a front end to a rear end; anda hopper assembly mounted to the rear end of the inclined ramp, the hopper assembly including a hopper bin extending past the rear end of the ramp to receive the material unloaded from the dump truck and simultaneously direct the material from a discharge opening of the hopper bin onto the conveyor assembly, wherein the hopper bin is pivotally mounted to the inclined ramp by a pair of support arms each connected to the hopper bin at an outer end and connected to a drive member at an inner end,wherein the drive member is operable to raise and lower the hopper bin relative to the inclined ramp between an upper position and a lower position along an arc defined by the pivoting movement of the support arms,wherein the distance between the discharge opening of the hopper bin and the rear end of the ramp varies as the hopper bin is moved along the arc between the upper position and the lower position.
