Abstract
A nurse inductor 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 inductor mechanism is detachably mounted on the meter box of the air seeder to receive a supply of seed particles therefrom. The nurse induction mechanism intercepts the normal air flow for the metering mechanism to divert 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 nurse induction mechanism in a stacked pair, modular configuration with the respective discharge tubes being adequately separated with r…
