Supply Hopper & Seed Wheel - USC LPX 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 and Section F: Troubleshooting;
"Proximity Switch Adjustment Guide" 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. From the weight of the seed sample and by also knowing the RPM of the
wheel, you can determine how fast that seed type will pass through the seed treater.
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.
