Patent Images
1. A chemical applicator for a farm implement with a conveyor, comprising:
- a hopper including a trough and a discharge spout;
an auger rotatably moving in said discharge spout and said trough of the hopper, said auger having a longitudinal axis of rotation; and
at least one agitator disc rotatably mounted in the hopper, the at least one agitator disc including a main body and a plurality of teeth protruding outwardly from the main body,wherein said at least one agitator disc is positioned in said hopper such that said auger engages one or more teeth of an agitator disc and causes the agitator disc to rotate when the auger rotates about said longitudinal axis of rotation.

Abstract
A chemical applicator for use in a farm implement including a hopper, an auger, at least one agitator disc mounted to the hopper and a proportional rate device. The chemical applicator is configured to store material in the hopper and discharge the material from the auger on to seed or grain discharged from the farm implement. The at least one agitator disc is positioned such that it is driven by the auger. Therefore, the agitator disc does not need a separate motor to drive it. The proportional rate device controls the rate of the auger relative to the rate at which seed or grain is discharged from the farm implement.
