Abstract

A hinge for a gauge wheel arm for movably swinging the gauge wheel away from the agricultural equipment, such as an agricultural planter, is disclosed. The hinge is located along the length of the gauge wheel arm for rotating the gauge wheel away from the agricultural equipment to expose an inner surface of the gauge wheel and an interior portion of the agricultural equipment. The gauge wheel arm rotates about an angle of rotation formed by the hinge and permitting rotation between 0 and 180 degrees. The gauge wheel arm may also include a lock bolt for preventing rotation of the gauge wheel when desired.

Claims

1. A gauge wheel assembly for an agricultural apparatus, comprising:

a gauge wheel arm including;

a first portion having a first end coupled to the agricultural apparatus and a second end; and

a second portion having first and second ends;

a gauge wheel rotatably supported on and coupled to the gauge wheel arm;

a hinge interconnecting the second end of the first portion of the gauge wheel arm to the first end of the second portion of the gauge wheel arm;

wherein the second portion of the gauge wheel arm is pivotable about a generally vertical axis on the hinge between a first position wherein the first and second portions of the gauge wheel arm extend along a common, generally horizontal axis and a second position wherein the second portion of the gauge wheel arm extends along an axis at an angle to the common axis; and

a lock bolt assembly having a first end operatively connected to the second end of the first portion of the gauge wheel arm and a second end operatively connected to the first end of the second portion of the gauge wheel arm, the lock bolt assembly including a lock bolt linearly movable along the generally horizontal axis between an unlocked position wherein the second portion of the gauge wheel arm is movable between the first and second positions, and a locked position wherein the lock bolt maintains the second portion of the gauge wheel arm in the first position.

2. The assembly of claim 1 wherein the hinge includes:

a first hinge plate interconnected to the second end of the first portion of the gauge wheel arm;

a second hinge plate interconnected to the first end of the second portion of the gauge wheel arm; and

a pivot pin pivotably connecting the first and second hinge plates.

3. The assembly of claim 2 wherein the first hinge plate includes a hinge passage and the second hinge plate includes a hinge passage, the pivot pin extending through the hinge passages of the first and second hinge plates.

4. The assembly of claim 2 wherein the pivot pin extends along a pivot axis generally perpendicular to the common axis.

5. The assembly of claim 1 wherein the angle is greater than 0 degrees and less than 180 degrees.

6. The assembly of claim 1 wherein the angle is greater than 0 degrees and less than or equal to 90 degrees.

7. A gauge wheel assembly of an agricultural apparatus, comprising:

a foldable arm having a first end operatively connected to the agricultural apparatus and a second end, the arm being foldable about a generally vertical fold axis between a non-folded position wherein the arm extends along a generally horizontal arm axis and a folded position wherein a first portion of the arm is at an angle less than 180 degrees to a second portion of the arm;

a gauge wheel rotatably mounted to the second end of the arm; and

a lock bolt assembly having a first end operatively connected to the first portion of the arm and a second end operatively connected to the second portion of the arm, the lock bolt assembly including a lock bolt linearly movable along the generally horizontal arm axis between an unlocked position wherein the arm is movable between the non-folded and folded positions, and a locked position wherein the lock bolt maintains the arm in the non-folded position.

8. The assembly of claim 7 further comprising a hinge interconnecting the first and second portions of the arm.

9. The assembly of claim 8 wherein the hinge includes:

a first hinge plate operatively connected to the first portion of the arm;

a second hinge plate operatively connected to the second portion of the arm; and

a pin pivotably coupling the first and second hinge plates, the pivot pin extending along the fold axis.

10. The assembly of claim 7 wherein the angle is less than 90 degrees.

11. A gauge wheel assembly for an agricultural apparatus, comprising:

a gauge wheel arm extending along an axis and including a first end operatively connected to the agricultural apparatus and a second end; and

a gauge wheel pivotably connected to the gauge wheel arm, the gauge wheel movable between a first position adjacent the agricultural apparatus and a second position wherein the gauge wheel is spaced from the agricultural apparatus; and

a lock bolt assembly having a first end operatively connected to a first portion of the gauge wheel arm and a second end operatively connected to the second portion of the gauge wheel arm, the lock bolt assembly including a lock bolt for maintaining the gauge wheel in the first position;

wherein;

in the first position, the gauge wheel lies in a plane parallel to the axis of the gauge wheel arm and in the second position, the plane of the gauge wheel is at an angle of less than 180 degrees to the axis; and

the lock bolt is linearly movable along the axis of the gauge wheel arm between an unlocked position wherein the gauge wheel arm is movable between the first and second positions, and a locked position wherein the lock bolt maintains the arm in the first position.

12. The assembly of claim 11 further comprising a pivotable arm having a first end pivotably coupled to the second end of the gauge wheel arm, the pivotable arm rotatably supporting the gauge wheel.

13. The assembly of claim 12 wherein the first end of the pivotable arm is pivotably coupled to the second end of the gauge wheel arm by a hinge.

14. The assembly of claim 13 wherein the hinge includes:

a first hinge plate operatively connected to the second end of the gauge wheel arm;

a second hinge plate operatively connected to first end of the pivotable arm; and

a pivot pin pivotably coupling the first and second hinge plates.

15. The assembly of claim 14 wherein the pivot pin is generally parallel to a plane through which the gauge wheel arm extends.
