An unloading apparatus is coupled to a dump truck loaded with dry bulk material to quickly unload the truck for return to service. The unloading apparatus is coupled to the outlet of the truck carrying its dry material load, and coupled to a receiver which receives the dry material discharged from the auger as the truck load bed is raised. Compressed air is delivered to the load bed along the sides and outlet to force the dry material dust to the outlet and out of the truck. A vibrator is coupled to the bed of the truck to aid in the discharge of the dry material load.

1. An apparatus for rapidly unloading a dry bulk material from a dump truck having a box trailer with a bed and sides, a hydraulic lift for raising and lowering a front end of the box trailer, and a rear panel, said apparatus comprising: an outlet having a generally pyramidal frustum shape with a base coupled to the box trailer below the rear panel and a truncated top opposite said base and projecting away from the box trailer,a valve having open and closed positions and coupled to said outlet to selectively control discharge of the dry bulk material from the dump truck, andan unloading auger having a receiver coupled to said truncated top of said outlet, a housing coupled to said receiver, a channel within said housing for receiving an auger, a motor for driving said auger, and a discharge,wherein dry bulk material is discharged from the box trailer and funneled through said outlet when the front end of the box trailer is raised by the hydraulic lift and said valve is in said open position, andwherein the dry bulk material is received by said unloading auger receiver and transferred through said housing channel to said discharge by said auger rotated by said motor. 2. The apparatus of claim 1 further comprising air rails coupled to air nozzles extending through opposite sides of said outlet to aerate the dry bulk material and blow the bulk dry material away from the sides of said outlet. 3. The apparatus of claim 1 further comprising a vibration unit coupled to the bed of the box trailer to aid in transfer of the bulk dry material from the box trailer to said outlet. 4. The apparatus of claim 1 further comprising an air line coupled to said discharge to force the bulk dry material through said discharge. 5. The apparatus of claim 1 wherein said motor is an electric motor. 6. The apparatus of claim 1 wherein said motor is a hydraulic motor. 7. The apparatus of claim 1 wherein said motor is a pneumatic motor. 8. An apparatus for rapidly unloading a dry bulk material from a dump truck having a box trailer with a bed and sides, a hydraulic lift for raising and lowering a front end of the box trailer, and a rear panel, said apparatus comprising: an outlet having a generally pyramidal frustum shape with a base coupled to the box trailer below the rear panel and a truncated top opposite said base and projecting away from the box trailer,a valve having open and closed positions and coupled to said outlet to selectively control discharge of the dry bulk material from the dump truck,an unloading auger having a receiver coupled to said outlet, a housing coupled to said receiver, a channel within said housing for receiving an auger, a motor for driving said auger, and a discharge,air rails coupled to air nozzles extending through opposite sides of said outlet and the box trailer, anda vibration unit coupled to the bed of the box trailer,wherein dry bulk material is discharged from the box trailer through said outlet when the front end of the box trailer is raised by the hydraulic lift and said valve is in said open position,wherein compressed air from said air nozzles aerate the dry bulk material and blow the bulk dry material away from the sides of said outlet and the box trailer,wherein vibrations from said vibration aid in transfer of the bulk dry material from the box trailer through said outlet, andwherein the dry bulk material is received by said unloading auger receiver and transferred through said housing channel to said discharge by said auger rotated by said motor. 9. The apparatus of claim 8 further comprising an air line coupled to said discharge to force the bulk dry material through said discharge. 10. The apparatus of claim 8 wherein said motor is an electric motor. 11. The apparatus of claim 8 wherein said motor is a hydraulic motor. 12. The apparatus of claim 8 wherein said motor is a pneumatic motor. 13. An apparatus for rapidly unloading a dry bulk material from a dump truck having a box trailer with a bed and sides, and a hydraulic lift for raising and lowering a front end of the box trailer, said apparatus comprising: an outlet having a generally pyramidal frustum shape with a base coupled to the box trailer below the rear panel and a truncated top opposite said base and projecting away from the box trailer,a valve having open and closed positions and coupled to said outlet to selectively control discharge of the dry bulk material from the dump truck through said outlet,an unloading auger having a receiver, a housing coupled to said receiver, a channel within said housing for receiving an auger, a motor for driving said auger, and a discharge,said receiver having a flange adapted to couple said unloading auger to said outlet,air rails coupled to air nozzles extending through opposite sides of said outlet and the box trailer,a vibration unit coupled to the bed of the box trailer, andan air line coupled to said discharge,wherein dry bulk material is discharged from the box trailer through said outlet when the front end of the box trailer is raised by the hydraulic lift and said valve is in said open position,wherein compressed air from said air nozzles aerate the dry bulk material and blow the bulk dry material away from the sides of the box trailer and said rear panel,wherein vibrations from said vibration aid in transfer of the bulk dry material from the box trailer through said outlet,wherein the dry bulk material is received by said unloading auger receiver and transferred through said housing channel to said discharge by said auger rotated by said motor, andwherein compressed air from said air line coupled to said discharge forces the bulk dry material through said discharge. 14. The apparatus of claim 13 wherein said motor is an electric motor. 15. The apparatus of claim 13 wherein said motor is a hydraulic motor. 16. The apparatus of claim 13 wherein said motor is a pneumatic motor.
