发明名称 Harvester swath pickup
摘要 A swath pickup includes a pair of spiders one on each end of a frame and angulated with respect to the direction of travel. A forked inwardly offset arm is pivotally secured to blocks on the outer ends of each arm of the spiders in the form of a universal joint and a transversely extending member from which pickup teeth extend, extends between each offset arm on one spider and the corresponding offset arm on the other spider. The spiders are rotated by a motor and the angular relationship of the spiders causes the members and the pickup teeth to reciprocate transversely as they rotate. The offset arms enable a pickup of reduced diameter to be provided which increases the efficiency of the pickup action yet provides sufficient room at the spiders for the installation and operation of the universal joints and arms to the spiders.
