Abstract

A support for a seed firming wheel of an agricultural planter. The support comprises a forked frame, a C-shaped link pivotally coupled to the forked frame and a spring positioned between the link and forked frame. The forked frame has a seed tube guard portion, two rearwardly extending arms, and a cross member that form a seed tube opening for receiving a seed tube and maintaining it in the center of the seed planting furrow. The forked frame is also provided with a pivot assembly to which the C-shaped link is mounted. The seed firming wheel is rotatively mounted to the C-shaped link.

Claims

1. A support for a seed firming wheel of an agricultural planter, the support comprising:

a forked frame having a seed tube guard portion which is provided with a mounting assembly for mounting the forked frame to the agricultural planter, the forked frame being provided with two rearwardly extending arms, the two rearwardly extending arms having a cross member, the forked frame defining a seed tube opening through which the seed tube of the planter is maintained in the center of a seed planting furrow, the forked frame also being provided with a pivot assembly, the pivot assembly having a spring assembly for applying a down pressure to the seed firming wheel;

a link pivotally mounted to the pivot assembly of the forked frame and extends rearwardly from the seed tube opening; and

the seed firming wheel being rotatively mounted to the link for firming seeds in a seed planting furrow.

2. The support as defined by claim 1 wherein the seed tube guard portion, the two rearwardly extending arms and the cross member of the forked frame are integral with one another.

3. The support as defined by claim 2 wherein the link is provided with a stop arm that bears against a stop on the forked frame to limit downward movement of the seed firming wheel.

4. The support as defined by claim 3 wherein the link is a C-shaped link having a forward end that is pivotally coupled to the pivot assembly and a rear end having a transversely extending axle to which is mounted the seed firming wheel.

5. The support as defined by claim 4 wherein the stop of the forked frame is formed by the cross member.

6. The support as defined by claim 5 further comprising a lockup link for locking the seed firming wheel into a non-working position.

8. The agricultural planter as defined by claim 4 the wherein the seed tube guard portion, the two rearwardly extending arms and the cross member of the forked frame are integral with one another.

9. The agricultural planter as defined by claim 8 wherein the link is provided with a stop arm that bears against a stop on the forked frame to limit downward movement of the seed firming wheel.

10. The agricultural planter as defined by claim 9 wherein the link is a C-shaped link having a forward end that is pivotally coupled to the pivot assembly and a rear end having a transversely extending axle to which is mounted the seed firming wheel.

11. The agricultural planter as defined by claim 10 wherein the stop of the forked frame is formed by the cross member.

12. The agricultural planter as defined by claim 11 further comprising a lockup link for locking the seed firming wheel into a non-working position.

7. An agricultural planter for applying seeds to a field, the planter comprising:

a frame;

a seed meter mounted to the frame for controlling the rate at which seeds are applied to the field;

a furrow opener mounted to the frame for opening a seed planting furrow to which seeds are applied from the seed meter;

a seed tube extending from the seed meter to the seed planting furrow for directing seeds into the seed planting furrow;

a seed firming wheel located behind the furrow opener in the furrow formed by the furrow opener, the seed firming wheel is provided with a support comprising a forked frame having a seed tube guard portion located in front of the seed tube which is mounted to the frame, the forked frame being provided with two rearwardly extending arms, the two rearwardly extending arms having a cross member, the forked frame defining a seed tube opening through which the seed tube of the planter being inserted and maintained in the center of the seed planting furrow, the forked frame also being provided with a pivot assembly, the pivot assembly having a spring assembly for applying a down pressure to the seed firming wheel, a link pivotally mounted to the pivot assembly of the forked frame and extending rearwardly from the seed tube opening, and the seed firming wheel being rotatively mounted to the link for firming seeds in the seed planting furrow.

13. A forked frame for an agricultural planter, the forked frame comprising:

a seed tube guard portion having a mounting assembly for mounting the forked frame to the agricultural planter;

two arms extending rearwardly from the frame; and

a cross member extending between the two arms, such that the seed tube guard portion, the two arms and the cross member define a seed tube opening for receiving a seed tube of the agricultural planter whereby the seed tube guard portion, the two arms and the cross member are integral with one another.

14. The forked frame as defined by claim 13 wherein each arm is provided with a pivot hole for receiving a pivot pin that spans the two arms.
