Injection hopper for use in a material delivery system
First Claim
1. A material injection hopper adapted for mounting on a movable working arm of a self-propelled vehicle, and for being 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, said injection hopper comprising:
- (a) a hopper body having an inlet for receiving the material to be delivered to the lagoon, and an outlet downstream of said inlet for discharging the material, said hopper body comprising a longitudinal injection chute formed at said outlet thereof, and a plurality of baffles extending longitudinally within said hopper body between said inlet and said outlet thereof for dividing said hopper body into separate compartments;
(b) an auger conveyor extending within the injection chute of said hopper body and arranged between said inlet and said outlet, and cooperating with the injection chute of said hopper body for moving the material entering said body downstream and outwardly through said outlet to the subsurface target area in the lagoon; and
(c) a protective guard attached to a free end of said injection chute to protect the end from damage as the working arm of the vehicle carries the injection hopper downwardly into and through the waste lagoon.

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.

8. A material injection hopper adapted for mounting on a movable working arm of a self-propelled vehicle, and for being 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, said injection hopper comprising:
-
(a) a hopper body having an inlet for receiving the material to be delivered to the lagoon, and an outlet downstream of said inlet, and a plurality of baffles extending longitudinally within said hopper body between said inlet and said outlet thereof for dividing said hopper body into separate compartments;
(b) a longitudinal injection chute formed at the outlet of said hopper body for delivering the material to a predetermined subsurface target area in the waste lagoon, the length of said injection chute being at least three times the diameter of said injection chute;
(c) an auger conveyor located within said hopper body and arranged between said inlet and said outlet for moving the material entering said body downstream and outwardly through said injection chute to the subsurface target area in the waste lagoon; and
(d) a protective guard attached to a free end of said injection chute to protect the end from damage as the working arm of the vehicle carries the injection hopper downwardly into and through the waste lagoon.

9. In combination with a waste mixer mounted on a free end of a movable and extendable working arm of a self-propelled vehicle, a material injection hopper attached to the working arm adjacent the waste mixer for being carried downwardly into and through a waste storage lagoon upon downward movement and extension of the working arm, said injection hopper comprising:
-
(a) a hopper body having an inlet for receiving a waste-processing material to be delivered to the lagoon, and an outlet downstream of said inlet, said hopper body comprising a longitudinal injection chute formed at said outlet thereof for discharging the waste-processing material to an area adjacent the waste mixer; and
(b) an auger conveyor extending within the injection chute of said hopper body and arranged between said inlet and said outlet, and cooperating with the injection chute of said hopper body for moving the waste-processing material entering said hopper body downstream and outwardly through said outlet, said auger conveyor permitting direct and controlled delivery of the waste-processing material from the injection chute to the area adjacent the waste mixer for immediate blending with the waste in a predetermined subsurface target area in the lagoon, such that the treated areas of the lagoon result in uniform hardness and consistency. - View Dependent Claims (10, 11, 12, 13, 14)
