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 an upper end of the fertilizer tube and an output opening at a lower end of the fertilizer tube, a tab attached to the fertilizer tube between the input opening and the output opening and a guard scraper attached to a lower portion of the fertilizer tube. The guard scraper includes a mounting portion having a receiver channel adapted to be removably attachable to a mounting member of a planter shank of a planter implement, wherein the mounting member is comprised of an inverted T-shaped structure.

Claims

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

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

wherein the fertilizer tube is comprised of a first segment, a second segment extending upwardly and forwardly from the first segment and a third segment extending upwardly from the second segment, wherein the first segment has a first angle with respect to a horizontal plane and wherein the second segment has a second angle with respect to the horizontal plane, and wherein the first angle is greater than the second angle; and

a guard scraper having a front edge, wherein the first segment of the fertilizer tube is attached to the front edge of the guard scraper, wherein the guard scraper includes a mounting portion having a receiver channel adapted to be removably attachable to a mounting member of a planter shank of a planter implement, wherein the mounting member is comprised of an inverted T-shaped structure.

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

3. The fertilizer tube of claim 1, including a tab attached to the fertilizer tube between the input opening and the output opening.

4. The fertilizer tube of claim 3, wherein the tab is attached to a central portion of the fertilizer tube.

5. The fertilizer tube of claim 3, wherein the tab has an initial position and a final position, wherein the initial position exists before the fertilizer tube is attached to the planter shank and wherein the final position exists after the fertilizer tube is attached to the planter shank.

6. The fertilizer tube of claim 5, wherein the tab extends transversely with respect to a plane that is parallel to a main body of the guard scraper extending from front to back of the guard scraper when the tab is in the initial position.

7. The fertilizer tube of claim 6, wherein the tab is approximately ninety-degrees with respect to the plane when the tab is in the initial position.

8. The fertilizer tube of system claim 6, wherein over fifty-percent of the tab is substantially parallel to the plane when the tab is in the final position.

9. The fertilizer tube of claim 1, wherein the output opening is within a lower distal end of the first segment, and wherein the first segment is comprised of a substantially straight structure that is substantially parallel to the front edge of the guard scraper.

10. The fertilizer tube of claim 1, wherein the first segment, the second segment and the third segment are all aligned along a common vertical plane.

11. The fertilizer tube of claim 1, wherein the third segment has a third angle with respect to the horizontal plane and wherein the third angle is greater than the first angle and the second angle.

12. The fertilizer tube of claim 1, wherein the third segment is substantially longer than either the first segment or the second segment.

13. The fertilizer tube of claim 12, wherein the third segment is longer than the first segment and the second segment added together.

14. The fertilizer tube of claim 12, wherein the second segment is shorter in length than the first segment.

15. The fertilizer tube of claim 1, wherein the third segment extends upwardly and forwardly from the second segment.

16. A method of attaching the fertilizer tube of claim 1, comprising:

positioning the mounting portion of the guard scraper so that a rear opening within the receiver channel is aligned with a front end of a lower shaft of the mounting member;

moving the guard scraper rearwardly so that the mounting portion slides upon the lower shaft of the mounting member until the front end of the lower shaft of the mounting member engages an enclosed end of the receiver channel;

rotating the guard scraper and the corresponding fertilizer tube; and

connecting the fertilizer tube to a fertilizer delivery tube from the fertilizer system.

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

the fertilizer tube having an input opening at an upper end of the fertilizer tube and an output opening at a lower end of the fertilizer tube, wherein the fertilizer tube is comprised of a continuous single structure, wherein the input opening is adapted for receiving fertilizer from a fertilizer system and wherein the output opening is adapted for dispensing the fertilizer into a seed furrow;

wherein the fertilizer tube is comprised of a first segment, a second segment extending upwardly and forwardly from the first segment and a third segment extending upwardly from the second segment, wherein the first segment has a first angle with respect to a horizontal plane and wherein the second segment has a second angle with respect to the horizontal plane, and wherein the first angle is greater than the second angle;

wherein the output opening is within a lower distal end of the first segment, and wherein the first segment is comprised of a substantially straight structure that is substantially parallel to the front edge of a guard scraper; and

the guard scraper having a front edge, wherein the first segment of the fertilizer tube is attached to the front edge of the guard scraper, wherein the guard scraper includes a mounting portion having a receiver channel adapted to be removably attachable to a mounting member of a planter shank of a planter implement, wherein the mounting member is comprised of an inverted T-shaped structure.

18. The fertilizer tube of claim 17, wherein the first segment, the second segment and the third segment are all aligned along a common vertical plane.

19. The fertilizer tube of claim 17, wherein the third segment has a third angle with respect to the horizontal plane and wherein the third angle is greater than the first angle and the second angle.

20. The fertilizer tube of claim 17, wherein the third segment extends upwardly and forwardly from the second segment.

21. A method of attaching the fertilizer tube of claim 17, comprising:

positioning the mounting portion of the guard scraper so that a rear opening within the receiver channel is aligned with a front end of a lower shaft of the mounting member;

moving the guard scraper rearwardly so that the mounting portion slides upon the lower shaft of the mounting member until the front end of the lower shaft of the mounting member engages an enclosed end of the receiver channel;

rotating the guard scraper and the corresponding fertilizer tube; and

connecting the fertilizer tube to a fertilizer delivery tube from the fertilizer system.

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

the fertilizer tube having an input opening at an upper end of the fertilizer tube and an output opening at a lower end of the fertilizer tube, wherein the fertilizer tube is comprised of a continuous single structure, wherein the input opening is adapted for receiving fertilizer from a fertilizer system and wherein the output opening is adapted for dispensing the fertilizer into a seed furrow;

wherein the fertilizer tube is comprised of a first segment, a second segment extending upwardly and forwardly from the first segment and a third segment extending upwardly from the second segment;

wherein the first segment has a first angle with respect to a horizontal plane, wherein the second segment has a second angle with respect to the horizontal plane and wherein the third segment has a third angle with respect to the horizontal plane;

wherein the first angle is greater than the second angle;
