Auger finger reversing mechanism.

摘要

A crop gathering attachment (1) for an agricultural harvester comprises : a rotatable auger-like conveyor (6) for transporting crop material, a stationary crank shaft mechanism (20) enclosed in the conveyor (6) and having a shaft portion (18) disposed eccentrically and parallel relative to the rotational axis of the conveyor (6); and a retractable finger arrangement (8) comprising a plurality of finger members (8) pivotally connected at their inner ends to said shaft portion (18) and projecting outwardly through guiding members (14) provided in the peripheral wall (10) of the conveyor (6); the arrangement being timed such that due to the eccentrical disposition of the shaft portion (18), the finger members (8) are reciprocated relative to said conveyor wall (10) upon rotation of the conveyor (6), thereby protruding from said wall (10) at one side of the conveyor (6) for projecting into the crop material and being retracted relative to said wall (10) at the generally diametrically opposed side of said conveyor (6) for releasing the transported crop. Actuator means (38) are operatively connected to the crank shaft mechanism (20) for remotely controlling the position of the shaft portion (18) relative to the conveyor (6) enabling on-the-go adjustments of the timing of the finger members (8). <IMAGE>
