Patent ID: 11528848

Abstract:
An agricultural baler includes a main bale chamber having an inlet for receiving crop material. A strawhook arrangement includes a plurality of strawhooks and an actuation mechanism for moving the strawhooks between an open position wherein the inlet to the main bale chamber is open, and a closed position wherein the inlet to the main bale chamber is closed. The actuation mechanism includes a two-bar linkage and an actuator. The two-bar linkage has a first bar with a first end and a second end, and a second bar with a first end and a second end. The first end of the first bar is pivotally coupled with the strawhooks, and the first end of the second bar is pivotally coupled with a fixed structure of the baler. The actuator is coupled with the second ends of the first bar and the second bar. The actuator is operable to apply pushing or pulling forces to each of the second ends and thereby selectively move the strawhooks between the open position and the closed position.
