Abstract
An agricultural harvesting machine includes a binding mechanism to secure binding material around a crop package and a delivery device to wrap binding material around a portion of the crop package and provide binding material to the binding mechanism. The delivery device includes a yoke, a needle coupling connected to the yoke, and a needle connected to the needle coupling.
Claims20
An agricultural harvesting machine comprising:
- a binding mechanism configured to secure binding material around crop material formed into a crop package;
- and
- a delivery device configured to wrap binding material around a portion of the crop package and provide binding material to the binding mechanism,
- wherein the delivery device includes:
- a yoke extending along a longitudinal axis;
- a needle coupling connected to the yoke, the needle coupling including a base having an outer portion, a first upper flange, and a first lower flange;
- and
- a needle connected to the needle coupling, the needle including a tip and a footing, the footing having a curved wall extending between a second upper flange and a second lower flange;
- wherein the needle is connected to the needle coupling by a first fastener extending through the first upper flange and the second upper flange, a second fastener extending through the first lower flange and the second lower flange;
- and
- wherein adjustment of the first fastener and the second fastener adjusts the position of the tip relative to the yoke, and
- wherein the yoke includes a hexagonal tube and the base includes a hexagonal inner portion.
