Seed Wheel - USC LPV Series Operator's Manual

The hopper is equipped with three proximity switches. The top switch controls the inlet
conveyor and the lower switches, located in the seed wheel, control the pump(s).
Refer to H-O-A Screen in section D. See the Proximity Switch Adjustment Guide
in Section F for more in-depth information on these switches.
The Seed Wheel is designed to simplify and increase seed flow calibration accuracy.
A rotating wheel is driven by a variable speed motor, which is set prior to treating the
seed. This is mounted above the atomizer. The wheel consists of 8 identical pockets
approximately 4 inches deep. As it rotates, the wheel captures a certain amount
of seed in each pocket. After the seed is caught, the wheel continues rotation and
dispenses the seed into the atomizer chamber. With the constant turn of the wheel,
there is a consistent amount of seed always sent through the atomizer.
A cup is used to represent a certain percentage of one of the wheels pockets.
To calibrate the seed flow, take a sample of the seed to be treated using the cup and
weigh it. (Refer to automation manual.) By entering the cup weight of the seed sample
the system will automatically adjust the RPM of the Seed Wheel according to the en-
tered target weight.
The purpose of the seed wheel is to simplify calibration and make seed flow calibration
more accurate. The seed wheel saves time when switching to different seed sizes and
seed types
