Abstract
A bulk unloader for emptying powder from an original box-shaped shipping container has a support platform with a cradle angularly mounted thereto for holding the container in a tilted position so that one of its corners is lower than the others. A vibrator, attached to the cradle, loosens the powder to facilitate movement of the powder towards the container's lowest corner. A pump connected to the outlet end of a hollow pick-up tube, having an inlet end positioned adjacent the container's lowest corner, draws powder from the container, into the inlet end of the pick-up tube, and then transfers the powder to a powder spray gun. The lower end of the pick-up tube is designed to prevent the plastic bag lining the shipping container from blocking the inlet end of the pick-up tube. A vibration dampening is provided between the cradle and the support platform to prevent vibrations from being transferred from the cradle to the support platform.
