1. A conveyor for a baler, the conveyor comprising:
a feed bar extending along an axial feed axis and comprising a first bar part, a second bar part, and a coupling connecting the first bar part and the second bar part to each other;
wherein the first bar part comprises a plurality of feed tines and a feed lever;
wherein the second bar part comprises a feed collection lever;
wherein the first bar part and the second bar part are connected to each other by the coupling such that, beginning from a stop position of the coupling, the first bar part and the second bar part are rotatable relative to each other about the axial feed axis in a first rotational direction against a restoring force and are coupled to each other in the stop position to prevent a rotation relative to each other in a second rotational direction that is opposite to the first rotational direction;
wherein the conveyor comprises a collection mode and a feed mode, wherein the conveyor is configured to convey crop within a collection chamber in a direction toward a press chamber by the plurality of feed tines of the first bar part in the collection mode and is further configured to convey crop from the collection chamber into the press chamber by the plurality of feed tines of the first bar part in the feed mode;
wherein the conveyor is configured to guide the first bar part in the collection mode by the feed collection lever of the second bar part and by a force transmission via the coupling;
wherein the conveyor is further configured to guide the first bar part in the feed mode at least partially by the feed lever of the first bar part by rotating the first bar part relative to the second bar part in the first rotational direction;
a drivable bar support, wherein the feed bar is rotatably supported about the axial feed axis at the drivable bar support, wherein the drivable bar support is a rotor unit drivable in rotation about a rotor axis that is spaced apart from the axial feed axis;
a collection guide element interacting with the feed collection lever of the second bar part to guide the first bar part in the collection mode, and further comprising a feed guide element interacting with the feed lever of the first bar part to at least partially guide the first bar part in the feed mode.
