Abstract

A trench opener/closer is provided for an agricultural seeding machine movable in a planting direction. The trench opener/closer includes a disc opener assembly, a gauge wheel assembly, a closing assembly, a boot member, and a seed delivery member. The disc opener assembly has a first axis of rotation. The gauge wheel assembly has a second axis of rotation disposed rearward of the first axis of rotation in the planting direction. The closing assembly has a third axis of rotation disposed rearward of the second axis of rotation in the planting direction. The boot member extends between the disc opener assembly and the closing assembly. The seed delivery member is disposed rearward of the disc opener assembly in the planting direction. The seed delivery member is disposed adjacent to both a trailing edge of the boot member and the closing assembly.

Claims

1. A trench opener/closer for an agricultural seeding machine movable in a planting direction comprising:

a disc opener assembly having a first axis of rotation;

a gauge wheel assembly having a second axis of rotation disposed rearward of said first axis of rotation in said planting direction;

a closing assembly having a third axis of rotation disposed rearward of said second axis of rotation in said planting direction;

a boot member extending from the disc opener assembly to the closing assembly; and

a seed delivery member disposed rearward of said disc opener assembly in said planting direction, the seed delivery member disposed adjacent to both a trailing edge of said boot member and the closing assembly.

2. The trench opener/closer of claim 1 wherein the disc opener assembly comprises a pair of disc opener blades.

3. The trench opener/closer of claim 1 wherein the gauge wheel assembly comprises two gauge wheels.

4. The trench opener/closer of claim 1 wherein said gauge wheel assembly is coupled to said disc opener assembly, and said gauge wheel assembly is vertically adjustable for adjusting a vertical position of the disc opener assembly relative to soil.

5. The trench opener/closer of claim 1 wherein said gauge wheel assembly is disposed adjacent or against a portion of said disc opener assembly, with the gauge wheel assembly overlapping the portion of said disc opener assembly relative to said planting direction, for removing soil from the disc opener assembly.

6. The trench opener/closer of claim 1 wherein said disc opener assembly includes a bearing housing, said gauge wheel assembly overlapping said bearing housing relative to said planting direction.

7. The trench opener/closer of claim 1 wherein said disc opener assembly defines a contact line with soil, and said gauge wheel assembly defines a gauge wheel contact patch with the soil, wherein said contact line is positioned forward and below said contact patch relative to said planting direction.

8. The trench opener/closer of claim 1 wherein said closing assembly is vertically adjustable for adjusting a vertical position of the closing assembly relative to soil.

9. The trench opener/closer of claim 1 wherein said closing assembly comprises two closing discs or two closing wheels.

10. The trench opener/closer of claim 1 wherein a bottom portion of said boot member is configured to keep a seed soil trench open from the disc opener assembly to the seed delivery member.

11. The trench opener/closer of claim 10 wherein the closing assembly is configured to close the seed soil trench as soon as the seed delivery member deposits seed in the seed soil trench.

12. The trench opener/closer of claim 1 wherein a leading edge of said boot member, relative to said planting direction, is disposed within said disc opener assembly and the trailing edge of said boot member, relative to said planting direction, is disposed within said closing assembly.

13. The trench opener/closer of claim 1 wherein the seed delivery member comprises a seed tube.

14. The trench opener/closer of claim 1 wherein the seed delivery member is coupled to the trailing edge of the boot member.

15. The trench opener/closer of claim 1 wherein the seed delivery member is disposed between two closing discs or two closing wheels of the closing assembly.

16. The trench opener/closer of claim 1 wherein the boot member extends from the disc opener assembly to the seed delivery member.

17. The trench opener/closer of claim 1 further comprising a frame carrying said disc opener assembly, said gauge wheel assembly, said closing assembly, said boot member, and said seed delivery member.

18. An agricultural seeding machine movable in a planting direction comprising:

a frame;

a disc opener assembly, carried by said frame, having a first axis of rotation;

a gauge wheel assembly, carried by said frame, having a second axis of rotation disposed rearward of said first axis of rotation in said planting direction;

a closing assembly, carried by said frame, having a third axis of rotation disposed rearward of said second axis of rotation in said planting direction;

a seed delivery member, carried by said frame, disposed rearward of said disc opener assembly in said planting direction; and

a boot member, carried by said frame, extending from the disc opener assembly to the closing assembly, wherein both the seed delivery member and a trailing edge of the boot member are positioned adjacent to the closing assembly.

19. A method of planting with an agricultural seeding machine moving in a planting direction comprising:

providing a disc opener assembly having a first axis of rotation disposed forward of a second axis of rotation of a gauge wheel assembly in said planting direction;

opening a seed trench in the soil with the disc opener assembly;

keeping the seed trench open from the disc opener assembly to a seed delivery member, disposed rearward of said disc opener assembly in said planting direction, using a boot member extending from the disc opener assembly to the closing assembly;

depositing a seed in the opened seed trench using the seed delivery member; and

closing the seed trench, as soon as the seed is deposited in the opened seed trench, using a closing assembly positioned proximate both a trailing edge of the boot member and the seed delivery member, wherein a third axis of rotation of the closing assembly is disposed rearward of said second axis of rotation in said planting direction.

20. The method of claim 19 further comprising removing the soil from the disc opener assembly using the gauge wheel assembly.
