Abstract

A seeding follower isolation device may include a forming bar connection portion, a seeding follower support portion, and an extension portion. The forming bar connection portion may be configured for secured attachment to a forming bar in a leading position relative to a seed tube of a planting unit. The seeding follower support portion may be configured to adjustably and removably support a seeding follower in an aft position relative to a seed tube. The extension portion may extend between the forming bar connection portion and the seeding follower support portion. The seeding follower isolation device does not contact a seed tube so that a seeding follower joined to the seeding follower isolation device is isolated from the seed tube.

Claims

1. A furrow assembly for a planting unit including a seed tube comprising:

a forming bar configured to be secured to a planting unit;

a seeding follower having a follower neck portion, a follower connection portion and a follower dragging portion, with the follower neck portion extending between the follower connection portion and the follower dragging portion and the follower dragging portion having a teardrop-shape that is positioned to gradually engage a furrow along a front side;

an isolation device having a forming bar connecting portion, an extension portion, and a follower support portion, which are configured to support the seeding follower off of the forming bar, the forming bar including a leading surface and a trailing surface, and the isolation device secured to the trailing surface; and

when the forming bar is secured to the planting unit, the forming bar leads a seed tube along a furrow, the isolation device positions the seeding follower in an aft position relative to the seed tube and isolates the seeding follower from the seed tube, and the seeding follower is configured to control bouncing seeds placed in the furrow by the seed tube.

2. The furrow assembly of claim 1, wherein the forming bar connecting portion includes a pair of inwardly turned flanges that mate against a trailing surface of the forming bar.

3. The furrow assembly of claim 2, wherein the connection between the flange and the forming bar includes a welded connection.

4. The furrow assembly of claim 2, wherein the connection between the flange and the forming bar includes a bolted connection.

5. The furrow assembly of claim 3, wherein the extension portion includes a pair of sidewalls in spaced apart relationship on opposing sides of the seed tube, wherein sidewalls include a top edge, a bottom edge, and a leading edge, with the leading edge positioned relative to the top edge at an angle in a range from approximately 5°

to approximately 10°

.

6. The furrow assembly of claim 5, wherein the sidewalls are spaced apart by a distance larger than a depth of the seed tube, thereby isolating the seed tube from vibrations imparted on the seeding follower, wherein the sidewalls extend from the pair of flanges at approximately 90°

.

7. The furrow assembly of claim 6, wherein the follower support portion includes a channel-shaped element for seating of the follower therein.

8. The furrow assembly of claim 7, wherein the seeding follower includes a connection portion having a width, and the channel-shaped element includes a pair of lateral flanges spaced apart a distance substantially equal to the width of the connection portion of the seeding follower providing for a snug fit therein.

9. The furrow assembly of claim 8, wherein the channel-shaped element further includes a connecting wall extending between the pair of lateral flanges, wherein the seeding follower connection portion is positioned on an inside surface of the channel shaped element and on the connecting wall.

10. The furrow assembly of claim 9, wherein the connecting wall includes apertures for fastening of the seeding follower thereto and the follower connection portion includes one or more connecting elements allowing for selective alignment of connecting elements with apertures in the connecting wall allowing for selective alignment of the one or more apertures of the connecting wall with the one or more of the connecting elements causing the seeding follower to be adjustably and removably supported at different elevations relative to the isolation device.

11. The furrow assembly of claim 1, wherein the planting unit includes a lead extending adjacent to the seed tube, the forming bar connecting portion, the extension portion, and the follower support portion are arranged to form an aperture, and the aperture configured for isolated passage therethrough of the seed tube and the lead.

12. The furrow assembly of claim 10, wherein the seeding follower includes an eyelet and one or more protrusions positioned on the same side of the seeding follower that is mated with follower connection portion the such that a fertilizer delivery sleeve positioned there between is supported on the seeding follower opposite of the front side and away from the furrow.

13. The furrow assembly of claim 12, wherein the bracket includes an extension portion including a pair of sidewalls and a follower support portion including a channel-shaped element having a pair of lateral flanges and a connecting wall, wherein the sidewalls, the pair of lateral flanges, and the connecting wall define an inside of the bracket and the follower is positioned inside the bracket.

14. A furrow assembly for a planting unit including a seed tube and a shank comprising:

a forming bar secured to a shank joined to a planting unit, the forming bar having a leading and trailing portion;

a seeding follower having a follower neck portion, a follower connection portion and a follower dragging portion, with the follower neck portion extending between the follower connection portion and the follower dragging portion, wherein the follower dragging portion is positioned to gradually engage a furrow along a front side; and

an isolation device configured to support a seeding follower off of the forming bar;

wherein;

the forming bar comprises an upper portion and a lower portion;

the upper portion of the forming bar is configured to be connected to the shank;

the isolation device is connected to the lower portion of the trailing portion of the forming bar by a pair of inwardly turned flanges that mate against a trailing surface of the forming bar; and

the forming bar leads a seed tube along a furrow, the isolation device positions the seeding follower in an aft position relative to the seed tube and isolates the seeding follower from the seed tube, and the follower connection portion of the seeding follower is adjustably mounted within the isolation device and is configured to control bouncing seeds placed in the furrow by the seed tube.
