ABSTRACT:
A compressed air discharge system for facilitating the unloading of material from the dump bed of such as a dump truck, and which is designed for interconnection with the compressed air system of the dump truck. The compressed air discharge system preferably includes an air tank having a conduit interconnected therewith for discharge of compressed air from such air tank and into the dump bed in juxtaposition to generate air shear planes through material lodged within the dump bed, an air supply circuit being interconnected to the compressed air system of the dump truck and the air tank for transmission of compressed air from the dump truck compressed air system to the air tank, the air supply circuit including a valve for selectively bleeding compressed air from the dump truck compressed air system and into the air supply circuit, a valve for preventing discharge of air from the air tank and back through the air supply circuit, and a quick release valve for discharge of a substantial blast of compressed air from the air tank and into the dump bed through the conduit interconnected to the air tank.
