SEEDER CALIBRATION APPARATUS AND METHOD

摘要

A system for performing an air-seeder calibration procedure comprises a calibration motor rotationally driving a plurality of metering devices simultaneously, thereby dispensing product from each metering device while the air-seeder cart is stationary. Meter controls, located on the air-seeder cart, are operative to stop any metering device while allowing the other metering devices to continue rotating. Containers collect the product dispensed from each metering device during the calibration procedure. Counters determine the number of revolutions turned by each metering device and are connected to a microprocessor. An input device allows entering of the weights dispensed by each metering device into the micro- processor and the micro-processor is operative to determine dispensing rates, being a weight of product dispensed per revolution, for each metering device. A distance sensor can be operatively connected to the microprocessor to determine the application rate for each metering device, and display the application rates to an operator.
