Nurse receiver and header for air seeders

In an agricultural implement for planting seeds into the ground and having a hopper for transporting a first supply of seeds, an air flow mechanism for creating a flow of air through a conduit to engage said first supply of seeds to entrain said seeds into a stream of air;

• and a planting mechanism to receive said flow of air and entrained seeds, the improvement comprising:
• a receiver header in flow communication with said air flow mechanism and a secondary reservoir, said receiver header being operable to direct the flow of seeds entrained in said air flow to at least two secondary reservoirs;
• a vent operatively coupled to each said reservoir and being operable to dissipate the air from said air stream and allow the entrained seeds to move into said secondary reservoir, said vent being located relative to said receiver header and the corresponding reservoir so that when said supply of seeds in said reservoir covers said vent, seeds are no longer conveyed to said reservoir;
• and
• said planting mechanism having a singulator for controlling the spacing of seeds being planted into the ground, the reservoir operatively coupled with said singulator providing a second supply of seeds for engagement by said singulator.

A seeding implement comprising:

• a mobile frame adapted for movement over the ground;
• a mechanism mounted on said mobile frame for creating and channeling a stream of air through a conduit;
• a hopper supported on said mobile frame for carrying a supply of seed particles, said hopper having a discharge opening for the passage of said seed particles;
• a planting mechanism for planting seeds into the ground, said planting mechanism having a singulator for spacing the planting of said seeds into the ground;
• a nurse mechanism operatively engaged with said hopper to communicate with said discharge opening and said conduit to receive seeds from said hopper and intercept the flow of air coming from said mechanism for creating an air stream through said nurse mechanism, said nurse mechanism entraining seeds within said air stream for conveyance through a discharge tube in flow communication with said nurse mechanism;
• a receiver operatively coupled to said singulator at said planting mechanism in flow communication with said discharge tube to receive seeds conveyed from said nurse mechanism through said discharge tube, said receiver accumulating a supply of seeds for utilization by said singulator;
• and
• a receiver header operatively coupled with said discharge tube and with said receiver to direct seeds entrained in said air stream toward said receiver, said receiver header having a vent therein for the dissipation of said air stream, said vent being located so that said seed can fall into said receiver after the air is dissipated from said air stream, the filling of said receiver with a supply of seeds sufficient to cover said vent halting the flow of air and entrained seeds to said reservoir.

• and
• a vent for the dissipation of said air stream, said vent being located so that said seed can fall by gravity into said receiver, the filling of said receiver with sufficient seeds to cover said vent effecting a halting of the flow of air and entrained seeds to said reservoir.

• and
• a hood covering said vent to minimize the entrance of contaminants into said vent.
