Air flow distribution control for curve compensation on air-seeding carts and tools

Abstract:

An air distribution system for a seed cart provides for improved air flow distribution upon identification of a turning event. The seed cart may have a fan operable to create an air stream. A set of primary tubes coupled to the fan may receive separate portions of the air stream from the fan. A distribution manifold may have a first plurality of passages therethrough and a second plurality of passages therethrough. A restrictor assembly may comprise a first end, a second end oppositely disposed from the first end, and a plurality of inlets and a plurality of outlets disposed therebetween. The restrictor assembly may have a plurality of restriction components. Restriction of air flow proximate the first end is different than the restriction of air flow proximate the second end.
