ABSTRACT:
The apparatus for directing a flow of air and cotton from a cotton conveyor duct of a cotton harvester into a cotton receiver includes a cover member and a mounting element configured for mounting the cover member to a cotton conveyor duct for movement between a first position located at least partially in a path of a flow of air and cotton discharged through a discharge outlet of the duct, and a second position located adjacent to the path for directing the flow therealong. The cover member when in the first position is movable to the second position by a force exerted thereagainst by a flow of at least air discharged from the duct. A locking element of the apparatus is configured for automatically holding the cover member in the second position, the locking element being automatically operable for releasing the cover member when a downward force is applied thereagainst by the cotton receiver for moving the cover member to the first position.
