Abstract
A material injection hopper is adapted for mounting on a movable working arm of a self-propelled vehicle. The injection hopper is carried downwardly by the working arm into a waste storage lagoon to deliver waste-processing material to a predetermined subsurface target area in the lagoon. The injection hopper includes a hopper body including an inlet for receiving the material to be delivered to the lagoon, and an outlet downstream of the inlet for discharging the material. An auger conveyor is located within the hopper body and arranged between the inlet and the outlet for moving the material entering the hopper body downstream and outwardly through the outlet to the subsurface target area in the lagoon.
