Abstract

A dual-disk seed meter for a planter may include a housing defining a first seed chamber configured to receive first seeds of a first seed type and a second seed chamber configured to receive second seeds of a second seed type. The seed meter may also include a first seed disk rotatable within the housing to convey the first seeds from the first seed chamber, a second seed disk rotatable within the housing to convey the second seeds from the second seed chamber, and a drive assembly configured to simultaneously rotate the first and second seed disks. In addition, the seed meter may include a seed deflector movable relative to the first seed disk and/or the second seed disk to control which of the seed types is discharged from the housing based on a selected seed type to be delivered by the seed meter.

First claim

What is claimed is:

1. dual-disk seed meter for a planter, the dual-disk seed meter comprising:
a housing defining a first seed chamber configured to receive a plurality of first seeds of a first seed type and a second seed chamber configured to receive a plurality of second seeds of a second seed type;
a first seed disk rotatable within the housing to convey the first seeds from the first seed chamber;
a second seed disk rotatable within the housing to convey the second seeds from the second seed chamber;
a drive assembly configured to simultaneously rotate the first and second seed disks relative to the housing; and
a seed deflector positioned within the housing and movable relative to at least one the first seed disk or the second seed disk to control which of the first and second seed types is discharged from the housing based on a selected seed type to be delivered by the seed meter.

2. The dual-disk seed meter of claim 1 , wherein, when the selected seed type is the first seed type, the seed deflector is moveable to a first position such that the first seeds remain coupled to the first seed disk as the first seeds are conveyed past the seed deflector with rotation of the first seed disk, and wherein, when the selected seed type is the second seed type, the seed deflector is moveable to a second position such that the first seeds conveyed towards the seed deflector with rotation of the first seed disk contact the seed deflector and fall back down into the first seed chamber.

3. The dual-disk seed meter of claim 2 , wherein, when in the first position, the seed deflector is disposed relative to the second seed disk such that the second seeds conveyed towards the seed deflector with rotation of the second seed disk contact the seed deflector and fall back down into the second seed chamber and, when in the second position, the seed deflector is disposed relative to the second seed disk such that the second seeds remain coupled to the second seed disk as the second seeds are conveyed past e seed deflector with rotation of the second seed disk.

4. The dual-disk seed meter of claim 3 , wherein the seed deflector includes a first deflector portion configured to be positioned relative to the first seed disk and a second deflector portion configured to be positioned relative to the second seed disk.

5. The dual-disk seed meter of claim 4 , wherein, when the seed deflector is at the first position, the first deflector portion is spaced apart from the first seed disk a spacing distance to allow the first seeds to pass by the first deflector portion with rotation of the first seed disk without contacting the first deflector portion and the second deflector portion is positioned directly adjacent to the second seed disk such that the second seeds conveyed towards the second deflector portion with rotation of the second seed disk contact the second deflector portion and fall back down into the second seed chamber.

6. The dual-disk seed meter of claim 4 , wherein, when the seed deflector is at the second position, the first deflector portion is positioned directly adjacent to the first seed disk such that the first seeds conveyed towards the first deflector portion with rotation of the first seed disk contact the first deflector portion and fall back down into the first seed chamber and the second deflector portion is spaced apart from the second seed disk a spacing distance to allow the second seeds to pass by the second deflector portion with rotation of the first seed disk without contacting the second deflector portion.

7. The dual-disk seed meter of claim 2 , wherein the seed deflector comprises a first seed deflector movable relative to the first seed disk between the first and second positions and further comprising a second seed deflector movable relative to the second seed disk between third and fourth positions.

8. The dual-disk seed meter of claim 7 , wherein, when the selected seed type is the first seed type, the second seed deflector is moved to the third position such that the second seeds conveyed towards the second seed deflector with rotation of the second seed disk contact the second seed deflector and fall back down into the second seed chamber, and wherein, when the selected seed type is the second seed type, the second seed deflector is moved to the fourth position such that the second seeds remain coupled to the second seed disk as the second seeds are conveyed past the second seed deflector with rotation of the second seed disk.

9. The dual-disk seed meter of claim 2 , wherein the seed deflector comprises a first upper seed deflector movable relative to the first seed disk, further comprising a first lower seed deflector movable relative to the first seed disk, the first upper and lower seed deflectors configured to be spaced radially apart from each other when at the first position.

10. The dual-disk seed meter of claim 9 , further comprising a second seed deflector separate from the seed deflector, the second seed deflector including second upper and lower seed deflectors movable relative to the second seed disk.

11. A dual-disk seed meter for a planter, the dual-disk seed meter comprising:
a housing defining a first seed chamber configured to receive a plurality of first seeds of a first seed type and a second seed chamber configured to receive a plurality of second seeds of a second seed type;
a first seed disk rotatable within the housing to convey the first seeds from the first seed chamber;
a second seed disk rotatable within the housing to convey the second seeds from the second seed chamber;
a drive assembly configured to simultaneously rotate the first and second seed disks relative to the housing; and
a seed deflector movable relative to at least one the first seed disk or the second seed disk to control which of the first and second seed types is discharged from the housing based on a selected seed type to be delivered by the seed meter,
wherein the seed deflector is configured to knock off at least one of the first seeds or the second seeds from the at least one of the first seed disk or the second seed disk, respectively, based on the selected seed type to be delivered by the seed meter.

12. The dual-disk seed meter of claim 11 , wherein, when the selected seed type is the first seed type, the seed deflector is moveable to a first position such that the first seeds remain coupled to the first seed disk as the first seeds are conveyed past the seed deflector with rotation of the first seed disk, and wherein, when the selected seed type is the second seed type, the seed deflector is moveable to a second position such that the first seeds conveyed towards the seed deflector with rotation of the first seed disk contact the seed deflector and fall back down into the first seed chamber.

13. The dual-disk seed meter of claim 12 , wherein, when in the first position, the seed deflector is disposed relative to the second seed disk such that the second seeds conveyed towards the seed deflector with rotation of the second seed disk contact the seed deflector and fall back down into the second seed chamber and, when in the second position, the seed deflector is disposed relative to the second seed disk such that the second seeds remain coupled to the second seed disk as the second seeds are conveyed past the seed deflector with rotation of the second seed disk.

14. The dual-disk seed meter of claim 13 , wherein the seed deflector includes a first deflector portion configured to be positioned relative to the first seed disk and a second deflector portion configured to be positioned relative to the second seed disk.
