Abstract

An air cart has a drop chute for conveying an agricultural product such as seed, from a metering device to a venturi portion of a product conveyance tube. The drop chute has a contoured downstream sidewall resulting in changes in drop chute width which introduce vortices providing an enhanced product flow. The downstream sidewall has an inward sloping region reducing the drop chute width beginning closely adjacent the metering device and continuing down about one-third the way from the metering device to the conveyance tube, and an abrupt corner causing an increase in drop chute width near the product conveyance tube followed by a curved region creating a gradual further increase in width terminating adjacent to the product delivery tube. A large low speed vortex is created near the inward sloping region and a small strong vortex is created adjacent the curved region.
