Control for a structural assembly self-aligningly supported on an agricultural machine

摘要

A control for a structural assembly oscillatingly supported around a swivel axis on a base unit in a harvesting machine and including a cutter table inclinably supported about an axis of rotation relative to a conveyor channel, has an hydraulic operation cylinder. The inclination of the cutter table relative to the conveyor channel is effected by the hydraulic operation cylinder pivoted at one end to the conveyor channel and at the other to the cutter table. An hydraulically loaded relief cylinder, the pressure medium of which is cushioned by a pressure reservoir, is installed with one end to the conveyor channel and with the other end to the cutter table so as to balance a position of the cutter table relative to its point of rotation by the force of the relief cylinder.
