Abstract

A planter apparatus includes a seed meter including a housing assembly with a cover releasably connected to a shell. The housing assembly includes at least one opening formed therein adjacent a seed discharge area to promote the release of seeds from a disc rotatably attached to the housing assembly. The disc divides an interior of the housing assembly to include a vacuum chamber and a seed chamber. The disc including a plurality of openings formed adjacent a periphery of the disc. The planter apparatus may also include a singulator assembly having rotatably spools, a rotatable chute door, a disc having clusters of openings for simultaneous release, and a one-piece baffle.

Claims

1. A seed planter apparatus comprising:

a seed meter including a housing assembly, the housing assembly including a cover releasably connected to a shell, the housing assembly including at least one opening formed in the housing assembly adjacent a seed discharge area to promote the release of seeds from a disc rotatably attached to the housing assembly, the disc dividing an interior of the housing assembly to include a vacuum chamber and a seed chamber, the disc including a plurality of openings formed adjacent a periphery of the disc, and wherein

the at least one opening formed in the housing assembly comprises a plurality of openings formed through the housing assembly.

2. The planter apparatus of claim 1 wherein the at least one opening is formed through the shell.

3. The planter apparatus of claim 1 wherein the at least one opening is formed in the cover.

4. The planter apparatus of claim 3 wherein the disc includes a center opening to receive an end portion of a rotatable shaft.

5. The planter apparatus of claim 3 wherein the shaft is received in an opening formed in a hub formed in the shell.

6. The planter apparatus of claim 5 wherein the hub is adapted to receive a baffle.

7. The planter apparatus of claim 1 wherein the seeds are partially covered by a singulator spool.

8. The planter apparatus of claim 7 wherein the singulator includes a plurality of spools.

9. The planter apparatus of claim 1 wherein the housing assembly includes an axially extending circumferential wall, the circumferential wall including an opening formed thereon to allow air to flow into the seed chamber.

10. The planter apparatus of claim 9 wherein the opening found in the circumferential wall is covered by a screen.

11. The planter apparatus of claim 1 wherein the seed disc is comprised of aliphatic polyketone.

12. The planter apparatus of claim 1 wherein the cover is comprised of plastic resin.

13. A method of operating a seed planter apparatus comprising the steps of:

providing a housing assembly including a cover releasably connected to a shell, the housing assembly including at least one opening formed in the housing assembly adjacent a seed discharge area, a disc rotatably attached to the housing assembly, the disc dividing an interior of the housing assembly to include a vacuum chamber and a seed chamber, the disc including a plurality of openings formed adjacent a periphery of the disc;

rotating the disc;

holding seeds in the disc openings while the disc openings align with the vacuum chamber for seed and air flow communication therewith;

releasing the seeds from the openings as the disc openings align with the vacuum chamber; and

flowing air through the opening formed in the housing assembly to promote the release of seeds from the disc.
