Abstract
A distribution ramp system for a dry product applicator with a pneumatic conveyance system is provided which lifts product that drags along a bottom surface(s) of a delivery line's wall(s) back into a main central or primary airflow portion that carries the product downstream through the pneumatic conveyance system. The system may include a ramp that nests against a bottom wall of the delivery line with a narrow front and wide back so the ramp presents a gradual wedge facing toward the incoming upstream airflow entrained with particulate material of the product, urging particulate material dragging on the bottom wall to lift away from the bottom wall and toward reentry into the primary airflow portion.
