Closing assembly for an agricultural implement
First Claim
1. A row unit for an agricultural implement comprising:
- at least one closing disc configured to move soil into a trench;
a coupling configured to support the at least one closing disc;
a first arm having a first end coupled to a center portion of the coupling and a second end configured to rotatably couple to a support structure of the row unit; and
a second arm having a first end rotatably coupled to an outer portion of the coupling and a second end configured to rotatably couple to the support structure of the row unit, wherein the outer portion of the coupling includes a bracket having a plurality of openings, and each opening of the plurality of openings is configured to receive an attachment element to rotatably couple the first end of the second arm to the bracket, wherein the outer portion of the coupling is rotatable relative to the center portion of the coupling, and rotation of the outer portion relative to the center portion drives a rotational axis of the at least one closing disc to revolve about a longitudinal axis of the center portion to enable the at least one closing disc to maintain a desired toe angle relative to a direction of travel or a desired camber angle relative to a surface of the soil as the row unit travels across a field.

Abstract
A row unit for an agricultural implement includes a closing disc configured to move soil into a trench. The row unit includes a first arm having a first end coupled to a center portion of a coupling and a second end configured to rotatably couple to a support structure of the row unit. A second arm includes a first end coupled to an outer portion of the coupling and a second end configured to rotatably couple to the support structure. The outer portion of the coupling is rotatable relative to the center portion, and rotation of the outer portion relative to the center portion drives a rotational axis of the closing disc to revolve about a longitudinal axis of the center portion to enable the closing disc to maintain a desired toe angle relative or a desired camber angle as the row unit travels across a field.

8. A row unit for an agricultural implement comprising:
-
a support structure; a closing disc coupled to the support structure, wherein the closing disc is configured to be positioned aft of an opener disc and to move soil into a trench formed by the opener disc as the agricultural implement travels across a field; a linkage assembly coupled to the support structure, the linkage assembly comprising; a coupling having a center portion and an outer portion; a plurality of support arms extending between the support structure and the coupling, the plurality of support arms comprising a first arm having a first end rotatably coupled to the support structure and a second end non-rotatably coupled to the center portion of the coupling; a second arm having a first end rotatably coupled to the support structure and a second end coupled to the outer portion of the coupling, wherein the second end of the second arm is rotatably coupled to a bracket of the outer portion, and the bracket comprises a plurality of openings each configured to receive an attachment element to rotatably couple the second end of the second arm to the bracket; and an angled disc mounting shaft extending laterally outward from the outer portion of the coupling at an angle relative to a longitudinal axis of the coupling, wherein the closing disc is rotatably mounted on the angled disc mounting shaft, and the outer portion and the angled disc mounting shaft are configured to rotate relative to the center portion of the coupling to maintain a desired angular relationship between the closing disc and a surface of the soil as the agricultural implement travels across a field. - View Dependent Claims (9)

10. A row unit for an agricultural implement comprising:
-
a support structure configured to be coupled to a frame of the row unit; a closing assembly, comprising; a coupling having a center portion and an outer portion; a closing disc configured to move soil into a trench, wherein the closing disc is supported by the outer portion of the coupling and is oriented at an angle relative to a longitudinal axis of the center portion of the coupling; a first support arm extending between the support structure and the center portion of the coupling; and a second support arm extending between the support structure and the outer portion of the coupling, the second support arm including a first end that is rotatably coupled to the support structure and a second end that is coupled to the outer portion of the coupling, wherein the second support arm is rotatably coupled to a bracket of the outer portion, and the bracket comprises a plurality of openings each configured to receive an attachment element to rotatably couple the second end of the second support arm to the bracket, and wherein the outer portion is configured to rotate relative to the center portion in response to movement of the closing disc vertically upward away from a surface of a field to maintain the angle between the closing disc and the longitudinal axis of the center portion of the coupling. - View Dependent Claims (11, 12, 13)
