BALER WITH A CONTROLLED RATE PRESERVATIVE APPLICATOR

摘要

BALER WITH A CONTROLLED RATE PRESERVATIVE APPLICATOR A rectangular baler has a preservative applicator for applying a fluid preservatipn to crop material as it is being baled as a function of the baling rate. The application rate is determined by a control circuit which repetitively measures the displacement of a charge of crop material through the baling for each cycle of the plunger and which repetitively opens solenoid controlled valves regulating a pressurized source of fluid preservative for a length of time proportionate to the magnitude of the displacement signal for one plunger cycle.
