Abstract

A method and system for planting one of a plurality of seed types, hybrids and/or varieties is provided. A planter is provided with a plurality of row units. The row units include metering systems, which can include a drum meter capable of metering multiple types of seed at the single drum. The metering system including the drum is configured such that the seed meter will plant different seed types or varieties. The operation the drum meter will provide for the planting of a particular seed variety. The invention provides for on-the-go changing of a seed being planted by the operation of the drum seed meter at each of the row units and provides for almost infinite variation among the row units for planting particular seed varieties or not planting at all.

First claim

What is claimed is:

1. A row unit for use with an agricultural planting implement and capable of planting a variety of seed types in a single field, the row unit comprising:
a seed meter comprising:
a. a rotatable seed drum including a plurality of seed paths comprising a plurality of seed cells spaced about the seed drum, each of said seed paths corresponding to one of the variety of seed types to be planted and each of the seed paths adjacent to one another on a single drum, said rotatable seed drum further comprising a plurality of seed pools corresponding to the number of seed paths; and
b. a discharge mechanism operatively connected to the plurality of seed paths, wherein operation of the discharge mechanism with a seed path will discharge a seed variety associated with said path from the seed cells; and

a seed to ground system for directing the selected seed variety associated with the selected seed path to the ground for planting.

2. The row unit of claim 1 , further comprising a seed delivery system for providing a plurality of varieties of seed to the row unit.

3. The row unit of claim 2 , wherein the seed delivery system comprises an air seed delivery system comprising at least one hose attached to at least one seed tank.

4. The row unit of claim 3 , wherein the air seed delivery system provides a separate seed variety to each seed pool.

5. The row unit of claim 4 , wherein seed is attached to the rotating drum as a particular seed cell of a seed path passes through the seed pool.

6. The row unit of claim 1 , wherein the rotatable seed drum is a substantially circular member.

7. The row unit of claim 1 , wherein the seed to ground system comprises a seed tube operatively attached to an exit of a seed chute to direct the seed to the ground.

8. The row unit of claim 1 , wherein the discharge mechanism comprises a member to knock a seed from a seed cell.

9. The row unit of claim 1 , wherein the discharge mechanism comprises a plurality of wheels selectively covering the seed paths, wherein the seed drum includes a reservoir for providing a pressure differential at the seed cells.

10. A method of planting one of a variety of seed in a field and switching the variety of seed being planted as a planter travels through the field, the method comprising:
delivering multiple varieties of seed to a seed drum at a row unit, said seed drum including a plurality of seed paths comprising a plurality of seed cells spaced about the seed drum, each of said seed paths corresponding to one of the variety of seed types to be planted and each of the seed paths adjacent to one another on a single drum;
determining one of the seed varieties to plant based, in part, on the location of the row unit in the field;
activating a discharge mechanism to the seed path associated with the determined seed variety to be planted, wherein the seed variety associated with the seed path will be directed towards an exit of the seed drum; and
directing the seed from the exit of the seed drum towards a planting location in the field.

11. The method of claim 10 , further comprising deactivating the seed paths associated with non-elected seed varieties, wherein the deactivating comprises shutting off a pressure differential at the seed paths.

12. The method of claim 10 , wherein the step of directing the seed from the exit of the seed drum towards a planting location in the field comprises the use of a seed to ground system.

13. The method of claim 12 , wherein the seed to ground system comprises a seed tube to control the movement of the seed after the exit from the seed drum.

14. The method of claim 10 , further comprising rotating the seed drum as the planter moves through the field.

15. The method of claim 10 , further comprising determining, based upon the location of the planter, if a different seed variety is to be planted.

16. The method of claim 15 , further comprising activating the discharge mechanism associated with the seed path for the different seed variety that has been determined to be planted, based upon the location of the planter in the field.

17. An agricultural planter for planting multiple varieties of seed in a field and capable of switching the variety of seed being planted as the planter travels through the field, the planter comprising:
a plurality of seed tanks containing different varieties of seed;
a plurality of row units operatively connected to the plurality of seed tanks for receiving the varieties of seed, the row units each comprising:
a seed meter comprising:
a. a seed drum including a plurality of seed paths comprising a plurality of seed cells spaced about the seed drum, each of said seed paths corresponding to one of the variety of seed types to be planted and each of the seed paths adjacent to one another on a single drum, said seed drum further comprising a plurality of seed pools corresponding to the number of seed paths; and
b. a discharge mechanism selectively operable with at least one of the plurality of seed paths such that operation of the discharge mechanism with a seed path will discharge a seed variety associated with said path from the seed cells.

18. The agricultural planter of claim 17 , further comprising a seed to ground system for directing the selected seed variety associated with the selected seed path to the ground for planting.

19. The row unit of claim 18 , wherein the seed to ground system comprises a seed tube extending substantially from the seed drum towards the ground.
