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.

2. The apparatus of claim 1 wherein the shell includes a seed opening found thereon to receive seed from a hopper, the seed opening movably covered by a baffle.

3. The apparatus of claim 2 wherein the baffle includes an adjustment handle which extends through an elongated opening found in the shell.

4. The apparatus of claim 3 wherein the shell includes a plurality of indentions to receive the adjustment handle and allows the baffle to be positioned to allow more or less seed to flow from the hopper into the seed chamber.

5. A seed metering apparatus for a seed planter comprising:

a housing including a seed chamber opening for communicating with a hopper, a baffle rotatably attached to the housing, the baffle including a body portion and a handle portion, the handle portion extending through an opening formed in the housing, the housing including a plurality of notches formed on an outer surface of the housing to allow the handle to be positioned within the notches to rotate the body portion and vary the size of the seed chamber opening.

6. The apparatus of claim 5 wherein the body portion of the baffle is retained by at least one retaining member.

7. The apparatus of claim 6 wherein the body portion is retained by a first retaining portion positioned adjacent a hub formed in the housing, the body portion including an opening for fitting onto the hub, the baffle rotatable about the hub.

8. The apparatus of claim 7 wherein the body portion is retained by a second retaining portion positioned adjacent a periphery of the housing.

9. The apparatus of claim 5 wherein the baffle is a one-piece baffle formed of plastic.

10. The apparatus of claim 5 wherein the baffle is a one-piece baffle formed of steel.

11. The apparatus of claim 5 further comprising a cover engaged with the housing, the cover including indicators inscribed on an outside surface of the cover and aligned with the notches.

12. A method of operating a seed metering apparatus for a seed planter comprising:

providing a housing including a seed chamber opening for communicating with a hopper, a baffle rotatably attached to the housing, the baffle including a body portion and a handle portion, the handle extending through an opening formed in the housing, the housing including a plurality of notches formed on an outer surface of the housing;

moving the handle portion between the notches;

retaining the handle portion in the notch;

rotating the body portion to vary the size of the seed chamber opening.

13. A seed planter apparatus comprising:

a seed meter including a housing assembly;

a disc rotatably mounted in the housing assembly and 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 for releasably holding seeds in response to a vacuum force;

a seed discharge area provided in the housing assembly to promote the release of seeds from the disc;

a seed opening in the housing to receive seeds from a source of seeds; and

a movable baffle associated with the seed opening to allow more or less seed to flow from the seed source into the seed chamber.

14. The apparatus of claim 13 wherein the baffle is movable between a closed position and an opened position.

15. The apparatus of claim 14 wherein the apparatus includes a mechanism to releasably retain the baffle in the closed position and a plurality of selected open positions.

16. The apparatus of claim 15 including indicia to indicate the position of the baffle and the degree of opening of the seed opening.

17. The apparatus of claim 13 wherein the apparatus includes a flexible handle connected to the baffle and extending through an elongated opening in the housing.

18. The apparatus of claim 17 wherein the baffle and handle are rotatably mounted and wherein the handle extends through an arcuate opening in the housing.

19. The apparatus of claim 18 wherein the housing includes a plurality of detents engagable with the flexible handle to releasably retain the baffle in a plurality of positions.
