Crop engaging device.

摘要

A crop engaging rotor for conveying and/or conditioning crop comprises support members (12) and a plurality of outwardly extending crop engaging elements (11). Each crop engaging element (11) comprises an elongate strip (20) of stiff resilient synthetic plastics material folded to form two outwardly extending arms (21) and (22) generally in a V-shape. The folded strip (20) is secured to a first flange (14) of a channel-section transverse mounting bar (12) which forms part of the rotor. The arms of the conditioning element protrude through openings in the support member (12) which provide guide surfaces (26) and (27), which maintain the folded strip (20) in the V configuration against the outward bias of the arms. The arms (21) and (22) are yieldable to move rearwardly under excess load conditions by a rocking movement about the bolt (23) and by sliding movement of the arms (21) and (22) along the guide surfaces (26) and (27). The element (11) is prevented from rotating about the bolt (23) by abutment of the arms (21) and (22) against the guide surfaces (26) and (27), and by abutment of the leading edge surfaces of the arms (21) and (22) against the inner surface of the upstanding portion (14A) of the member (12).
