Abstract

A fertilizing and seeding apparatus for attachment to a cultivator shank includes an adapter for rigid attachment to the cultivator shank and a fertilizer blade and a double blade seeder. Only forward pivotal motion of the tools from a normal operating position is readily permitted thus minimizing possible clogging of fertilizer and seed outlet apertures, and/or facilitating the cleaning of such apertures.

Claims

1. An apparatus for simultaneously fertilizing and seeding and adapted to connect to a cultivator shank, said apparatus comprising:

an adapter member fixedly securable to said shank and having means for individually conveying fertilizer and seed respectively;

a fertilizer blade pivotally attached to said adapter having means to channel fertilizer from said adapter to a distal end of said fertilizer blade; and

a seeder blade pivotally attached to said adapter having means to channel seed from said adapter to a plurality of distal ends of said seeder blade.

3. Apparatus as in claim 1 wherein said seed applying tool is a plural banding air seed applicator comprising:

a vertical shank portion substantially aligned to follow in the wake of said fertilizer applying tool during said forward movement and having a seed inlet aperture at an upper portion thereof; and

a horizontal blade portion extending on both sides of a lower portion of said vertical shank portion and having plural seed outlet apertures, communicating internally with said seed inlet aperture, and disposed at lower rearwardly situated locations on said horizontal blade portion.

4. Apparatus as in claim 3 wherein said fertilizer applying tool includes a fertilizer inlet aperture at an upper portion thereof and at least one fertilizer outlet aperture disposed at a lower rearwardly situated location thereon.

5. Apparatus as in claim 4 wherein said adapter member includes a pair of generally vertical apertures therethrough having lower outlets which respectively mate with said fertilizer inlet aperture in the fertilizer applying tool and said seed inlet aperture in the seed applying tool when said tools are in their abutted rearwardly pivoted normal operating positions with respect to the adapter member.

2. Apparatus for applying supplied material to soil during forward movement of a tool through the soil;

said apparatus comprising;

an adapter member including (i) first means for effecting substantially fixed attachment of the adapter member to another structure, (ii) second means for effecting pivotal attachment of at least one material application tool to the adapter member and (iii) stop abutment means; and

at least two material applicator tools each having a soil cutting forward edge and a material supplying outlet aperture at a lower rear portion thereof;

each said tool being pivotally mounted to the adapter member via said second means so as to define a fixed operating tool position when rearwardly pivoted into engagement with said stop abutment means during said forward movement through the soil while yet permitting substantially free forward pivotal motion of the tool with respect to the adapter member;

one of said tools being a fertilizer applying tool pivotally attached to a forwardly situated portion of said adapter member and the other being a seed applying tool pivotally attached to a rearwardly situated portion of said adapter member.

6. An apparatus for simultaneously fertilizing and seeding and adapted to connect to a cultivator shank, said apparatus comprising:

an adapter member fixedly securable to said shank and including a pair of conduits for individually conveying fertilizer and seed respectively;

a fertilizer blade pivotally attached to said adapter and including means limiting pivoting motion of the fertilizer blade in a backward direction to the working position and having a fertilizer conveying channel communicating with one of said conduits at said normal operating position and extending to a distal end of said fertilizer blade; and

a double seeder blade pivotally attached to said adapter and including means limiting pivoting motion of said double seeder blade in a backward direction to the working position and a seed conveying channel communicating with the other of said conduits at said normal operating position and extending to a distal end of said double seeder blade.

7. An apparatus for simultaneously fertilizing and seeding and adapted to connect to a shank of a cultivator, said apparatus comprising:

an adapter securable to said shank, said adapter comprising a base portion with a top side and a bottom side, and two flange portions depending from said bottom side of said base portion, said flange portions defining a receiving channel, said receiving channel forming a forward opening and a rearward opening, said base portion also having two apertures passing through said base portion, a fertilizer aperture from said top side to said forward opening, and a seed aperture from said top side to said rearward opening;

a fertilizer blade comprising an elongated blade having a front side and a rear side and a top end and a bottom end, said elongated blade having a cutting edge on said front side, said elongated blade also having a fertilizer delivery channel formed therein with a fertilizer inlet at said top end and a fertilizer outlet at said bottom end of said rear side;

a first pivot means for connecting said adapter to said fertilizer blade and for permitting pivoting of said fertilizer blade into an operating position whereby said top end of said elongated blade is matingly received by said forward opening such that said top end abuttingly engages said base portion between said flange portions and said fertilizer aperture aligns with said fertilizer delivery channel;

a double blade seeder comprising a top blade section and left and right blade section projecting laterally and downwardly from said top blade section, each of said blade sections having a forward side and a rearward side and an upper end and a lower end, each of said blade sections also having a leading edge on said forward side, said double blade seeder having a seed delivery channel formed therein with a seed inlet at said upper end of said top blade section and a seed outlet at each said lower end of said rearward side of said left blade section and said right blade section; and

a second pivot means for connecting said adapter to said double blade seeder and for permitting pivoting of said double blade seeder into an operating position whereby said upper end of said top blade section is matingly received by said rearward opening such that said upper end abuttingly engages said base portion between said flanges and said seed aperture aligns with said seed delivery channel.

8. An apparatus as in claim 7 wherein said seed outlet of said left blade section is about 6 inches from said seed outlet of said right blade section.

9. The apparatus of claim 7 wherein said fertilizer outlet is two inches lower than said seed outlet of said right blade section and said seed outlet of said left blade section, when said apparatus is in the operating position.

10. An apparatus as in claim 7 wherein said first pivot means comprises two aligned apertures in said flange portions, a fertilizer blade aperture at said top end of said fertilizer blade, and a pin.

11. An apparatus as in claim 10 wherein said pin includes a nut and bolt.

12. An apparatus as in claim 7 wherein said second pivot means comprises two aligned second apertures in said flange portions, a double blade seeder aperture at said upper end of said top blade section, and a second pin.

13. An apparatus as in claim 12 wherein said second pin includes a second nut and second bolt.

14. An apparatus as in claim 7 wherein a fertilizer boss is connected on said topside of said base portion over said fertilizer aperture and, a seed boss is connected on said topside of said base portion over said seed aperture.

15. An apparatus as in claim 7 wherein said fertilizer blade and said double blade seeder are made from high strength and high wear resistant chrome moly steel.

16. An apparatus as in claim 7 wherein a plastic tube is clamped to an inside wall of said fertilizer aperture, and passes through said fertilizer delivery channel.

17. An apparatus as in claim 7 wherein said bottom end of said fertilizer blade forms a pointed edge.

18. An apparatus as in claim 7 wherein said lower end of said left blade section and said right blade section form parallel pointed edges.
