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 chute portion and a seed chamber, the chute portion including a first opening for receiving seed from a hopper which communicates with the first opening, the chute portion including a second opening formed therein, a bar extending from a portion of the chute portion and positioned above the second opening, a door shaped to cover the second opening and including a clip portion for snap-fitting onto the bar to allow the door to rotate on the bar.

2. The apparatus of claim 1 wherein the door is made of plastic.

3. A method of operating a seed planter apparatus comprising:

providing a seed meter including a housing assembly, the housing assembly including a chute portion and a seed chamber, the chute portion including a first opening in communication with a hopper, the chute portion including a second opening formed therein, a bar extending from a portion of the chute portion and positioned above the second opening, a door shaped to cover the second opening and including a clip portion snap fitted to the bar;

rotating the door about the bar;

passing seed from the hopper through the first opening; and

passing seed through the second opening.

4. A seed planter apparatus comprising:

a seed meter including a housing assembly including a chute portion and a seed chamber, the chute portion including a first opening for receiving seed from a seed source, a lower portion of the chute portion further including a second opening for removing seeds from the chute portion, a door shaped to cover the second opening movably mounted on the housing assembly, and a retaining member to releasably retaining the door in a position to close the second opening in the chute portion.

5. The seed planter apparatus of claim 4 wherein the door is removably mounted on the housing assembly for easy installation and removal.

6. The seed planter apparatus of claim 4, Wherein the retaining member comprises a locking member positioned on the lower portion of the chute portion.

7. The seed planter apparatus of claim 6, wherein the housing assembly includes a receiving member adjacent the lower portion of the second opening positioned to receive and releasably retain the locking member.

8. A method of operating a seed planter apparatus comprising:

providing a seed meter including a housing assembly, the housing assembly including a seed chamber and a chute portion, the chute portion including a first opening to receive seeds and a second opening to discharge seeds, and a door mounted to the housing assembly shaped to cover the second opening and movable between an open position and a closed position covering the second opening;

passing seed into the chute portion through the first opening with the door in a closed position;

moving the door from the closed position to the open position to open the second opening; and

passing seed through the second opening in the chute.

9. A method of operating a seed planter apparatus comprising:

providing a seed meter including a housing assembly, the housing assembly including a seed chamber in a chute portion, the chute portion including a first opening to receive seeds and a second opening to discharge seeds, a door mounted to the housing assembly shaped to cover the second opening and movable between an open position and a closed position covering the second opening, and a retaining member to releasably retain the cover in the closed position;

passing seed into the chute portion through the first opening with the door in a closed position;

releasing the retaining member and moving the door from the closed position to the open position to open the second opening; and

passing seed through the second opening in the chute portion.

10. A seed planter apparatus comprising:

a seed meter including a housing assembly, the housing assembly including a chute portion and a seed chamber, the chute portion including a first opening for receiving seed from a hopper which communicates with the first opening, the chute portion including the second opening formed therein, a bar extending from a portion of the chute portion and positioned above the second opening, a door shaped to cover the second opening and including a clip portion for snap-fitting onto the bar to allow the door to rotate on a bar and further including a receiving portion, and a pin for insertion into the receiving portion on the door which locks the door to the housing assembly.

11. A seed planter apparatus comprising:

a seed meter including a housing assembly including a chute portion and a seed chamber;

the chute portion including a first opening for receiving seed from a seed source, a lower portion of the chute portion further including a second opening for removing seeds from the chute portion, a door shaped to cover the second opening movably mounted on the housing assembly above the second opening, and a locking member positioned on a lower portion of the chute portion to releasably lock the door in a position to close the second opening in the chute portion.

12. The seed planter apparatus of claim 11 wherein the door is removably mounted on the housing assembly for easy installation and removal.
