Abstract:
In an agricultural seeding implement having a frame adapted for movement over the ground; a hopper supported on said frame for carrying a supply of seed, said hopper having a lower portion including a discharge opening through which seed particles pass to exit said hopper; and a mechanism supported on said frame for creating a flow of air through a conduit, the improvement comprising:a nurse mechanism supported on said hopper to communicate with said discharge opening and said conduit so as to receive seeds from said hopper and intercept the flow of air coming from said mechanism for creating an air stream through said mechanism to distribute seed to a secondary metering mechanism, said nurse mechanism having:a partition wall positioned between a mass of seeds and a flow path for said stream of air created within said nurse mechanism, said partition wall helping to direct said flow of air in a serpentine path passing adjacent to a pile of seed particles to create a turbulence to enhance the entrainment of said seed particles into said flow of air, and said partition wall defining an access opening through which said mass of seeds are funneled into a pile of seed particles adjacent said flow path for said air such that said stream of air can entrain individual seed particles; anddischarge tubes in communication with said flow path for said stream of air to direct the entrained seed particles to a remote planting mechanism.
