Abstract

A shank-mounted opener assembly connected to a seed distribution system is provided for both till and no-till operations. The opener assembly includes a spike member that is supported on the shank, a firming point, a seed sensor connected to the seed supply, a seed boot, a seed locking mechanism, and a multi media delivery tube assembly. The seed boot encloses the seed sensor and includes a pair of lateral side walls. The seed boot protects the seed sensor from moving soil and debris. The seed locking mechanism pushes the seed into the soil and forms a shallow layer of soil over the seed dispensed through the seed sensor. If desired, assistive media can be dispensed into the furrow at the same time as seeding. The assistive media are dispensed through the multi-media delivery tube assembly. The assistive media are not dispensed to the furrow until after the seed locking mechanism covers the seed with a shallow layer of soil.

Claims

1. A ground opener assembly attachable to a mounting device and connectable to a seed distribution system that is conveyed by an off road vehicle comprising:

a downwardly-pointing spike member attachable to said mounting device conveyed by said vehicle for engagement with the ground so as to form a furrow therein;

a seed sensor in communication with said seed distribution system through which seed is dispensed into said furrow;

a seed boot enclosing said seed sensor; and

a firming point positioned between said spike member and said seed boot.

2. The opener assembly of claim 1 wherein said seed boot comprises a first lateral side wall located adjacent one side of said seed sensor and a second lateral side wall located adjacent an other side of said seed sensor.

3. The opener assembly of claim 2 wherein the firming point is mounted to said seed boot.

4. The opener assembly of claim 2 wherein said seed sensor is positioned between said first and said second lateral side walls of said seed boot.

5. The opener assembly of claim 1 further comprising a seed locking mechanism attached to said seed boot to push said seed into said furrow and to urge a layer of soil over said seed dispensed into said furrow.

6. The opener assembly of claim 1 further comprising at least one media delivery tube integral with said seed boot, said at least one media delivery tube in communication with at least one storage container carried on said off-road vehicle.

7. The opener assembly of claim 1 further comprising at least two media delivery tubes integral with said seed boot, said at least two media delivery tubes in communication with at least two storage containers carried on said off-road vehicle.

8. The opener assembly of claim 7 wherein said media delivery tubes dispense particulates from said storage containers conveyed by said off-road vehicle.

9. The opener assembly of claim 1 further comprising at least one sweep mounted between said spike member and said seed boot.

10. The opener assembly of claim 9 wherein said sweep can be mounted between said spike member and said seed boot at more than one height.

11. A ground opener assembly attachable to a mounting device and connectable to a seed distribution system that is conveyed by an off road vehicle comprising:

a downwardly pointing spike member attachable to said mounting device conveyed by said vehicle for engagement with the ground so as to form a furrow therein;

a seed sensor in communication with said seed distribution system, said seed sensor having an open lower distal end from which seed is dispensed into said furrow; and

a seed boot enclosing said open lower distal end of said seed sensor.

12. The opener assembly of claim 11 further comprising a firming point mounted to said seed boot between said spike member and said seed sensor.

13. The opener assembly of claim 11 further comprising at least one sweep mounted between said spike member and said seed boot.

14. The opener assembly of claim 11 further comprising a seed locking mechanism attached to said seed boot to push said seed into said furrow and to urge a layer of soil over said seed dispensed into said furrow.

15. The opener assembly of claim 11 further comprising at least one media delivery tube integral with said seed boot, said at least one media delivery tube in communication with at least one storage container carried on said off-road vehicle.

16. A ground opener assembly attachable to a mounting device and connectable to a seed distribution system that is conveyed by an off road vehicle comprising:

a spike member attachable to said mounting device conveyed by said vehicle for engagement with the ground so as to form a furrow therein;

a seed sensor in communication with said seed distribution system to dispense seed into said furrow;

a seed boot enclosing said seed sensor;

a seed locking mechanism attached to said seed boot to push said seed into said furrow and to urge a layer of soil over said seed dispensed into said furrow; and

at least one media delivery tube positioned so as to trail said seed locking mechanism on said seed boot, said at least one media delivery tube in communication with at least one storage container carried on said off-road vehicle.

17. The opener assembly of claim 16 wherein said seed boot comprises a first lateral side wall located adjacent one side of said seed sensor and a second lateral side wall located adjacent an other side of said seed sensor.

18. The opener assembly of claim 16 wherein said seed sensor has an open lower distal end from which said seed is dispensed.

19. The opener assembly of claim 16 further comprising a firming point mounted on the seed boot between said spike member and said seed sensor.

20. The opener assembly of claim 16 further comprising at least one sweep mounted between said spike member and said seed boot.
