Deblocking Apparatus for a Work Machine

A combine harvester comprising:

• a dynamic feed roll;
• and
• an apparatus mounted on the dynamic feed roll for actuating a rocking motion, the apparatus comprising:
• an actuator comprising a movable component;
• a lever configured to be subjected by the actuator to an angular displacement in two opposite directions with respect to a neutral positional range;
• a force transfer element attached to the movable component, wherein the lever is provided with a pair of oppositely placed pawls which are shaped so as to engage with the force transfer element so that:
• both pawls are prohibited from engaging with the force transfer element when the lever is within the neutral positional range;
• the force transfer element and thereby the movable component are displaced in the first of the two opposite directions by the first pawl engaging with the force transfer element, when the lever exits the neutral positional range in the first direction;
• and
• the force transfer element and thereby the movable component is displaced into the second of the two opposite directions by the second pawl engaging with the force transfer element, when the lever exits the neutral positional range in the second direction.
