Walking beam closing disk assembly
First Claim
Patent Images
1. A closing disk assembly for an agricultural implement having a support frame, the closing disk assembly comprising:
- a mounting assembly having a frame mount;
a support arm pivotally coupled to the mounting assembly;
a rocker assembly coupled to the support arm;
a walking beam pivotally coupled to the rocker assembly about a pivot axis, the walking beam having first and second beam segments that are oriented at different angles with respect to the pivot axis and a reference plane;
a first and a second disk mount coupled to each of the first and second beam segments on opposite sides of the pivot axis; and
first and second closing disks, the first closing disk rotatably mounted to the first disk mount and the second closing disk rotatably mounted to the second disk mount to a side of the walking beam opposite the first closing disk;
wherein the first and second disk mounts of the walking beam are offset from the reference plane of the closing disk assembly such that the first and second closing disks are oriented at different angles with respect to the respective first and second beam segments.

Abstract
An agricultural implement has a closing disk assembly for closing furrows along a section of ground. The closing disk assembly has a pair of closing disks attached to opposite sides and opposite ends of a walking beam. The closing disks are offset from a reference plane of the closing disk assembly. The walking beam is rotatably coupled to the closing disk assembly through a rocker assembly, a support arm, and a mounting assembly. The walking beam may rotate relative to the rocker assembly to account for variations in the angle of the ground relative to the disks.

11. An agricultural implement, comprising:
- a support frame; and
a disk gang having a plurality of closing disk assemblies mounted to the support frame;
wherein each closing disk assembly includes;
a mounting assembly having a frame mount;
a support arm pivotally coupled to the mounting assembly;
a rocker assembly coupled to the support arm;
a walking beam pivotally coupled to the rocker assembly about a pivot axis passing through the walking beam and having first and second beam segments, the pivot axis being essentially perpendicular to a direction of travel of the implement;
a pair of disk mounts opposingly mounted on opposite ends of the pivot axis; and
a first closing disk and a second closing disk rotatably mounted to the disk mounts each on an opposite side of the walking beam;
wherein the first closing disk rotates about a first axis, the second closing disk rotates about a second axis;
wherein a reference plane is perpendicular to the pivot axis and each closing disk is canted with respect to the reference plane at about the same angle; and
wherein the first and second beam segments are oriented with respect to the reference plane at different angles and wherein the first and second closing disks are oriented at different angles with respect to the respective first and second beam segments. - View Dependent Claims (12)
