Abstract
The present invention is directed to an applicator having an agricultural product pneumatic conveying system which meters particulate material from one or more source containers at the application equipment and transports the particulate material to evenly distribute the particulate material from the applicator. The pneumatic conveying system employs supply lines connected between the metering devices at the source containers and delivery nozzles. The conveying system also includes a dynamic baffle system that directs the air flow towards a supply line detected as having increased resistance to the air flow in order to equalize the air flow into each of the supply lines. The baffle system accomplishes this by obstructing a portion of the air flow towards a supply line having less resistance to the air flow and concurrently re-directing the obstructed portion of the air flow into the supply line with higher air flow resistance.
