Abstract

A seeding boot for use with a cultivator shank and utilized for delivering particulate material such as seed, fertilizer, chemicals or the like to soil prepared by a soil working tool comprises a soil deflector which defines a surface for deflecting soil over the seeds deposited on the prepared soil, and thereafter allows the soil to cover the seeds, and a diffusing member matingly engageable with the soil deflecting member for diffusing the seeds or the like into substantially parallel rows and includes a downstream portion which abuts against the inner surface of the soil deflecting member and an upper surface portion separated from the lower surface portion by a predetermined dimension so that together with the soil deflecting member will define an interior cavity through which the particulate matter will be directed, a portion of the upper surface being biased so as to receive various sizes of seed conduits and to increase the versatility of use of the seeding boot.

Claims

1. An air seeding boot used to deliver material such as seed, fertilizer, or chemicals to be deposited onto the soil prepared by a soil working tool, the boot being adapted to mount on a mounting shank together with a soil working tool and to be secured to the shank with at least one bolt also used to mount the soil working tool thereto in such a manner that the bolts used do not fasten across a part of the boot which is easily compressed, said boot comprising:

a front part for the purpose of deflecting the soil moved by the soil working tool away from the area where dispensed material will be deposited;

a back part which diffuses and separates dispensed material into two portions and allows the material to be deposited on the soil prepared by the soil working tool in two rows generally separated and generally equal; and

the two said parts mating with one another to form a hollow body having an opening on the top portion for receiving a material delivery conduit, and having two generally equal openings on the bottom portion of the hollow body, the openings being of generally oval shape inclined backward and upward from the lower portion of the hollow body

the two said parts being directly and rigidly bolt-connectable to said shank by said working tool mounting bolt which bolt avoids passage through said hollow body.

2. An air seeding boot as in claim 1 in which the material delivery conduit is resiliently received within the top end of the boot.

3. A boot for delivery particulate material such as seed, fertilizer, chemicals, or the like entrained in a moving fluid, such as air, to be deposited onto the soil prepared by a soil working tool and adapted for operative connection to a shank and to a conduit for directing said entrained material from a source thereof, said boot comprising:

8. A boot as in claim 7 wherein each of said first and second surface defining means includes leading and trailing edge portions, said entrained material deflecting means being rigidly disposed between said trailing edge portion of said first surface defining means and said leading edge portion of said second surface defining means.

9. A boot as in claim 8 wherein said second surface defining means includes biasing means for inwardly biasing said second surface defining means so that clamping engagement can be effected with said conduit.

10. A boot as in claim 5 further comprising securing means for rigidly securing said diffusing means to said shank, and preliminary deflecting means upstream of said entrained material deflecting means for preliminarily deflecting said entrained material.

11. A boot as in claim 10 wherein said securing means and preliminary deflecting means are integral with one another and comprise threadably engageable bolt means for securing said diffusing means to said shank, said bolt means extending a predetermined dimension into said cavity so as to preliminarily deflect said entrained material.

12. A boot as in claim 11 wherein said securing and preliminary deflecting means is generally centrally disposed in said cavity.

13. An air seeding boot adapted for physical attachment to a soil working tool mounting shank and to a conduit source of particulate agricultural materials, said boot comprising:

a one-piece first member at least partially closed upon itself so as to partially define a hollow particulate distribution chamber as a generally concave-shaped portion thereof;

said one-piece first member having at least one aperture therethrough for direct bolted connection to said mounting shank; and

a one-piece second member having at least one aperture therein for direct bolted connection to at least one of said mounting shaft and said first member and having a portion angularly bent-away from the aperture therein and which bent-away portion cooperates with said generally concave-shaped portion of the first member to define said hollow particulate distribution chamber

said direct bolted connection apertures being located to avoid bolt passage through said hollow particulate distribution chamber while simultaneously permitting direct bolted connection by said bolt of a soil working tool to said mounting shank and thus transferring substantially the same compression mounting forces to said first and second members at the location of said bolt connection apertures thereby avoiding any tendency to compress said chamber and/or to loosen said soil working tool.

14. An air seeding boot as in claim 13 wherein each of said first and second members diverge from a top end to a substantially wider bottom end, mating apertures in said first and second members being disposed proximate the wider ends thereof such that, when bolt-connected together, they define a particulate divider which results in a two-row delivery of particulates from the boot.

15. In combination with a device of the type for entraining a particulate material, such as seed, fertilizer, chemicals, or the like and for depositing said material onto the soil as said device is advanced across the surface of said soil, and including a source of said particulate material, means for entraining predetermined amounts of said material in a moving fluid, shank means supporting a soil working tool and conduit means for directing said entrained material from said material source to said soil rearwardly of said soil working tool, the improvement comprising a boot rigidly attached to said shank for delivering said material in at least two substantially parallel rows onto said soil prepared by said soil working tool as it advances through said soil, said boot comprising:
