Wing hinge coupling device

A coupling device for an agricultural implement having a main frame section, a wing frame section pivotally attached to the main frame section such that the agricultural implement can unfold and fold in between a work position and a transport position, and at least one conveyance line, the coupling device including:

• a first coupling member configured for attaching to a first line portion of the at least one conveyance line associated with the main frame section;
• and
• a second coupling member pivotally connected to the first coupling member at a pivot axis and configured for attaching to a second line portion of the at least one conveyance line associated with the wing frame section such that the first and second coupling members are configured for unfolding to couple the first line portion and the second line portion of the at least one conveyance line in the work position and for folding to uncouple the first line portion and the second line portion of the at least one conveyance line in the transport position;
• wherein the at least one conveyance line is one of a pneumatic air line and a hydraulic fluid line.

A method, comprising the steps of:

• providing an agricultural implement including a frame with a main frame section and at least one wing frame section pivotally connecting the at least one wing frame section to the main frame section, thereby defining a hinge line, such that the agricultural implement is configured for pivoting in between a work position and a transport position in which the at least one wing frame section is folded relative to the main frame section, at least one conveyance line supported by the frame and having a first line portion associated with the main frame section and a second line portion associated with the at least one wing frame section, and at least one coupling device, supported by the frame, and including a first coupling member attached to the first line portion of the at least one conveyance line and a second coupling member pivotally connected to the first coupling member at a pivot axis and attached to the second line portion of the at least one conveyance line, wherein the at least one conveyance line is one of a pneumatic air line and a hydraulic fluid line;
• unfolding the first and second coupling members to couple the first line portion and the second line portion of the at least one conveyance line by unfolding the at least one coupling device as the at least one wing frame section unfolds relative to the main frame section to be in the work position;
• and
• folding the first and second coupling members to uncouple the first line portion and the second line portion of the at least one conveyance line by folding the at least one coupling device as the at least one wing frame section folds relative to the main frame section to be in the transport position.
