Abstract

A no-till drill liquid fertilizer applicator system for effectively protecting a fertilizer dispensing tube on a no-till drill while dispensing liquid fertilizer with small grain seed. The no-till drill liquid fertilizer applicator system includes a receiver tube, a guide tube attached to the receiver tube to receive a fertilizer tube, and a wear member removably received within the receiver tube. The fertilizer tube extends through the guide tube to within a guide channel within an upper portion of the wear member and continues to a rear portion of the wear member to dispense the liquid fertilizer upon a seed bed.

Claims

1. A no-till drill liquid fertilizer applicator system, comprising:

a receiver tube including a receiver opening;

a guide tube attached to said receiver tube to receive a fertilizer tube; and

a wear member removably received within said receiver opening of said receiver tube, wherein said wear member receives an end portion of said fertilizer tube and wherein said fertilizer tube terminates adjacent to a rear portion of said wear member.

2. The no-till drill liquid fertilizer applicator system of claim 1, wherein said wear member includes a guide channel for receiving said end portion of said fertilizer tube.

3. The no-till drill liquid fertilizer applicator system of claim 2, wherein said guide channel extends along an upper portion of said wear member to said rear portion.

4. The no-till drill liquid fertilizer applicator system of claim 3, including a first guide aperture within said wear member connected to said guide channel, wherein said first guide aperture receives said fertilizer tube and wherein said first guide aperture is substantially parallel to an initial path of said guide channel.

5. The no-till drill liquid fertilizer applicator system of claim 4, including a second guide aperture within said wear member connected to said guide channel, wherein said second guide aperture receives said fertilizer tube and wherein said second guide aperture is substantially parallel to an end path of said guide channel.

6. The no-till drill liquid fertilizer applicator system of claim 2, including a lower guide member extending from said rear portion of said wear member.

7. The no-till drill liquid fertilizer applicator system of claim 6, wherein said lower guide member includes an aperture that receives said end portion of said fertilizer tube.

8. The no-till drill liquid fertilizer applicator system of claim 2, wherein said guide channel has a rounded cross sectional structure.

9. The no-till drill liquid fertilizer applicator system of claim 2, wherein said guide channel has a depth equal to at least a diameter of said fertilizer tube.

10. The no-till drill liquid fertilizer applicator system of claim 1, wherein said guide tube is comprised of an elongated structure having a first end and a second end, wherein said fertilizer tube enters said first end and exits said second end.

11. The no-till drill liquid fertilizer applicator system of claim 1, including a collar attached to said guide tube, wherein said guide tube is to receive a shaft of a no-till drill.

12. The no-till drill liquid fertilizer applicator system of claim 11, wherein said collar is comprised of a rectangular structure.

13. The no-till drill liquid fertilizer applicator system of claim 1, wherein said receiver tube includes a first aperture, wherein said wear member includes a second aperture aligned with said first aperture, wherein a fastener is extended through said first aperture and said second aperture for securing said wear member within said receiver tube.

14. The no-till drill liquid fertilizer applicator system of claim 1, wherein said receiver opening is comprised of a rectangular cross section.

15. The no-till drill liquid fertilizer applicator system of claim 1, wherein said wear member includes a neck portion that has a cross sectional shape corresponding to said receiver opening.

16. The no-till drill liquid fertilizer applicator system of claim 15, wherein said neck portion is narrower than a main body of said wear member.

17. The no-till drill liquid fertilizer applicator system of claim 1, wherein said wear member has a lower surface that engages a ground surface.

18. The no-till drill liquid fertilizer applicator system of claim 1, wherein said wear member includes a tapered leading edge.

19. A no-till drill liquid fertilizer applicator system, comprising:

a receiver tube including a receiver opening;

a guide tube attached to said receiver tube to receive a fertilizer tube, wherein said guide tube is comprised of an elongated structure having a first end and a second end, wherein said fertilizer tube enters said first end and exits said second end;

a wear member removably received within said receiver opening of said receiver tube, wherein said wear member receives an end portion of said fertilizer tube, and wherein said fertilizer tube terminates adjacent to a rear portion of said wear member;

wherein said wear member has a lower surface that engages a ground surface and a tapered leading edge;

a guide channel within said wear member for receiving said end portion of said fertilizer tube, wherein said guide channel extends along an upper portion of said wear member to said rear portion, wherein said guide channel has a rounded cross sectional structure, and wherein said guide channel has a depth equal to at least a diameter of said fertilizer tube;

a first guide aperture within said wear member connected to said guide channel, wherein said first guide aperture receives said fertilizer tube and wherein said first guide aperture is substantially parallel to an initial path of said guide channel;

a second guide aperture within said wear member connected to said guide channel, wherein said second guide aperture receives said fertilizer tube and wherein said second guide aperture is substantially parallel to an end path of said guide channel;

a lower guide member extending from said rear portion of said wear member, wherein said lower guide member includes an aperture that receives said end portion of said fertilizer tube;

a collar attached to said guide tube, wherein said collar is formed is to receive a shaft of a no-till drill, wherein said collar is comprised of a rectangular structure;

wherein said receiver tube includes a first aperture, wherein said wear member includes a second aperture aligned with said first aperture, wherein a fastener is extended through said first aperture and said second aperture for securing said wear member within said receiver tube;

wherein said receiver opening is comprised of a rectangular cross section;

wherein said wear member includes a neck portion that has a cross sectional shape corresponding to said receiver opening; and

wherein said neck portion is narrower than a main body of said wear member.
