Abstract

A fertilizer tube system for efficiently dispensing and placing fertilizer within a furrow to minimize germination injury. The fertilizer tube system generally includes a fertilizer tube having an input opening at a lower end of the fertilizer tube and an output opening at an upper end of the fertilizer tube, a tab attached to the fertilizer tube between the input opening and the output opening, a guard scraper attached to a lower portion of the fertilizer tube, wherein the guard scraper is removably attachable within a slot of a planter shank.

Claims

1. A fertilizer tube system for attachment to a planter implement, comprising:

a fertilizer tube having an input opening at an upper end of said fertilizer tube and an output opening at a lower end of said fertilizer tube, wherein said input opening is adapted for receiving liquid fertilizer from a liquid fertilizer system and wherein said output opening is for dispensing said liquid fertilizer into a seed furrow;

a tab attached to said fertilizer tube between said input opening and said output opening, wherein said tab is comprised of a bendable material; and

a guard scraper attached to a lower portion of said fertilizer tube, wherein said guard scraper is adapted to be removably attachable within a slot of a planter shank of a planter implement.

2. The fertilizer tube system of claim 1, wherein said fertilizer tube is comprised of a continuous single structure.

3. The fertilizer tube system of claim 2, wherein said fertilizer tube is comprised of a rigid material.

4. The fertilizer tube of system claim 3, wherein said fertilizer tube is comprised of a metal.

5. The fertilizer tube of system claim 1, wherein said tab is comprised of a bendable metal material.

6. The fertilizer tube of system claim 1, wherein said tab is attached to a central portion of said fertilizer tube.

7. The fertilizer tube system of claim 1, wherein said tab is welded to said fertilizer tube.

8. The fertilizer tube system of claim 1, wherein said fertilizer tube is attached to a lower leading edge of said guard scraper.

9. The fertilizer tube system of claim 1, wherein said guard scraper is welded to said fertilizer tube.

10. The fertilizer tube system of claim 1, wherein said fertilizer tube has a circular cross sectional area.

11. The fertilizer tube system of claim 1, wherein said tab is comprised of a flat structure.

12. The fertilizer tube system of claim 1, wherein said tab has an initial position and a final position, wherein said initial position exists before said fertilizer tube system is attached to said planter shank and wherein said final position exists after said fertilizer tube system is attached to said planter shank.

13. The fertilizer tube system of claim 12, wherein said tab extends transversely with respect to a plane that is parallel to a main body of said guard scraper extending from front to back of said guard scraper when said tab is in said initial position.

14. The fertilizer tube system of claim 13, wherein said tab is approximately ninety-degrees with respect to said plane when said tab is in said initial position.

15. The fertilizer tube system of claim 13, wherein over fifty-percent of said tab is substantially parallel to said plane when said tab is in said final position.

16. The fertilizer tube system of claim 1, wherein said guard scraper includes a front edge, a rear portion and a mounting portion, wherein said fertilizer tube is attached to said front edge of said guard scraper.

17. The fertilizer tube system of claim 16, wherein said rear portion is comprised of a flanged structure extending outwardly on opposing sides of a body portion of said guard scraper.

18. The fertilizer tube system of claim 1, wherein said fertilizer tube is comprised of a first segment attached to a front edge of said guard scraper and a second segment extending upwardly from said first segment at an angle, wherein said output opening is within a lower distal end of said first segment, wherein said first segment is comprised of a substantially straight structure that is substantially parallel to said front edge of said guard scraper and wherein said second segment is comprised of a substantially straight structure that is substantially parallel to said leading edge of said planter shank.

19. The fertilizer tube system of claim 18, wherein said fertilizer tube is comprised of a third segment that extends substantially horizontally from said second segment and a fourth segment that extends upwardly from said third segment.

20. A fertilizer tube system for attachment to a planter implement, comprising:

a fertilizer tube having an input opening at an upper end of said fertilizer tube and an output opening at a lower end of said fertilizer tube, wherein said input opening is adapted for receiving liquid fertilizer from a liquid fertilizer system and wherein said output opening is adapted for dispensing said liquid fertilizer into a seed furrow;

a tab attached to said fertilizer tube between said input opening and said output opening, wherein said tab is comprised of a bendable material;

a guard scraper attached to a lower portion of said fertilizer tube, wherein said guard scraper is adapted to be removably attachable within a slot of a planter shank of a planter implement;

wherein said guard scraper includes a front edge, a rear portion and a mounting portion, wherein said fertilizer tube is attached to said front edge of said guard scraper; and

wherein said slot within said planter shank is comprised of a T-slot and wherein said mounting portion of said guard scraper is comprised of a T-shaped structure that snugly fits within said T-slot of said planter shank.
