Apparatus for regulating the position of a cutting mechanism

摘要

The invention relates to an apparatus for regulating the position of a cutting mechanism for a combine harvester, in the case of which the cutting mechanism is arranged such that it can be pivoted transversely with respect to the direction of travel. The essential features of the invention consist in that the pendulum support (3) is arranged within a guide (12, 13, 14) such that it is guided positively on a circle-arc section. A hydraulic cylinder (21) is arranged between the pendulum support (3) and the frame (2) connected to the draw-in conveying channel (4). The hydraulic cylinder (21) is connected, via a directional valve (22) and a further directional valve (26), to an accumulator (27). The directional valves (22, 26) can be controlled via sensors (23, 25). <IMAGE>
