Lpx300 Seed Wheel Overview - USC LPX 2000 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 G: 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 24 pockets
(8 small, 8 medium and 8 large) approximately 2 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 the wheels pockets. To calibrate
the seed flow, take a sample of the seed to be treated using the cup and weigh it
(see page 43). By entering the cup weight of the seed sample the system will
automatically adjust the RPM of the Seed Wheel according to the entered 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.
