Abstract
A nurse adapter mechanism for an agricultural seeding implement converts an air seeder meter box into a nurse inductor box to convey seed particles to the singulator of a planting mechanism. The nurse adapter mechanism is detachably mounted on the meter box of the air seeder to receive a supply of seed particles therefrom and utilizes the normal air flow for the metering mechanism to effect a nursing of seed particles to a planting mechanism. The nurse adapter mechanism diverts the stream of air into engagement with a pile of seed particles and induce the entrainment of the seed particles for conveyance thereof to the remote planting mechanism. A partition wall divides the nurse induction mechanism into a seed side and an air side. The seed side receives the supply of seed particles from the hopper and allows the seed to pass through a passageway into the air side for engagement by the stream of air. Divider walls are provided to isolate each discharge tube from the other discharges tube so that the planter mechanisms can provide a continuous supply of seed particles. The discharge tubes pass through the seed side of the nurse adapter mechanism in a stacked pair, modular configurat…
