Abstract

An extension for use with a planter, drill, or other farming implement having a seed tube that deposits seed in a furrow. The extension defines protrusions for attaching one or more liquid distribution apparatuses arranged to distribute liquid in a furrow well above the seeds, on the seeds, or both.

Claims

1. A liquid distribution system for a farm machine that is configured to place seeds in a furrow, the liquid distribution system comprising:

a liquid supply conduit;

an extension configured for selective attachment to the farm machine and including an extension fluid passage extending from a top surface of the extension to a bottom surface of the extension; and

a fluid distribution member joined to the extension, the fluid distribution member including a body defining a fluid inlet in fluid communication with the liquid supply conduit, a fluid outlet arranged over the extension fluid passage and in fluid communication therewith, and a fluid passage that fluidly connects the fluid inlet with the fluid outlet, the fluid passage extending between the fluid inlet and the fluid outlet and the fluid passage including a first portion and a second portion extending away from the first portion at an angle relative to the first portion.

2. The liquid distribution system of claim 1, wherein the second portion of the fluid passage extends generally downwardly from the first portion of the fluid passage.

3. The liquid distribution system of claim 1, wherein the extension includes an upper segment attachable to the farm machine and a lower segment including first and second protrusions extending from the top surface of the extension.

4. The liquid distribution system of claim 3, wherein the fluid distribution member is located between the first and the second protrusions.

5. The liquid distribution system of claim 3, wherein the first and second protrusions each define an aperture configured to receive first and second fasteners, respectively.

6. The liquid distribution system of claim 5, further comprising a retainer plate selectively joined to the first protrusion with the first fastener and to the second protrusion with the second fastener.

7. The liquid distribution system of claim 6, wherein the fluid distribution member is located between the first and second protrusions, and the retainer plate in conjunction with the first and second protrusions secures the fluid distribution member to the extension.

8. The liquid distribution system of claim 5, wherein:

the fluid distribution member includes a first flange extending from the body and defining an aperture configured to receive the first fastener therethrough and a second flange extending from the body and defining an aperture configured to receive the second fastener therethrough; and

the fluid distribution member is joined to the extension through receipt of the first fastener in the apertures of the first protrusion and the first flange and receipt of the second fastener in the apertures of the second protrusion and the second flange.

9. The liquid distribution system of claim 1, wherein the farm machine comprises a furrow opener.

10. The liquid distribution system of claim 1, wherein the farm machine comprises a seed tube.

11. The liquid distribution system of claim 10, wherein the extension is joined to the seed tube.

12. The liquid distribution system of claim 1, wherein the fluid distribution member is positioned on the top surface of the extension.

13. A liquid distribution system for a farm machine that is configured to place seeds in a furrow, the liquid distribution system comprising:

a liquid supply conduit;

an extension configured for selective attachment to the farm machine and including an extension fluid passage extending from a top surface of the extension to a bottom surface of the extension; and

a fluid distribution member joined to the extension, the fluid distribution member including a body defining a fluid inlet in fluid communication with the liquid supply conduit, a fluid outlet in fluid communication with the extension fluid passage, and a fluid passage that fluidly connects the fluid inlet with the fluid outlet, the fluid passage extending between the fluid inlet and the fluid outlet and the fluid passage including a first portion and a second portion extending away from the first portion at an angle relative to the first portion;

wherein, the liquid supply conduit, the extension, and the fluid distribution member define a fluid path and the fluid distribution member is arranged between the liquid supply conduit and the extension along the fluid path.

14. A liquid distribution system for a farm machine that is configured to place seeds in a furrow, the liquid distribution system comprising:

a liquid supply conduit;

an extension configured for selective attachment to the farm machine and including an extension fluid passage extending from a top surface of the extension to a bottom surface of the extension; and

a fluid distribution member fluidly coupled between the liquid supply conduit and the extension, the fluid distribution member including a body defining a fluid inlet in fluid communication with the liquid supply conduit, a fluid outlet in fluid communication with the extension fluid passage, and a fluid passage that fluidly connects the fluid inlet with the fluid outlet, the fluid passage extending between the fluid inlet and the fluid outlet and the fluid passage including a first portion and a second portion extending away from the first portion at an angle relative to the first portion.
