The aim of the invention is to mount the cutting elements in a height-elastic manner in order to allow the cutter bar to be guided as close to the base as possible and in the process reduce the risk of damage in the event of contacting the base. This is achieved in that the adjustment drive () is rotatably connected to a first side () of a rocker lever () which can be rotated about an axis () and the second side () of which rotatably engages with an energy store () that is adjustable in length, and the frame part () can be moved against the force of the energy store () that is adjustable in length by the swinging arms () via a rocking movement of the rocker lever () about the axis () miming transversely to the working direction of the cutting mechanism () when a lifting force acts on at least one swinging arm ().

Cutting mechanism with cutting elements which are mounted in a height-elastic manner

The present invention related to a cutting unit for attachment to the height-adjustable intake duct of a harvester. In order to improve the sensor-supported height guidance of cutting units it is proposed to provide at least one additional load sensor which measures the load with which the cutting unit loads the intake duct, in order to calculate a height-control-relevant signal from the transmitted sensor values of the distance sensor and the load sensor via an evaluation device which the signal is transmitted to the interface.

Cutting unit having sensors for height control

A harvesting head has a middle section connected to a carrier device and at least one side section connected by an articulated connection to the middle section about which the side section pivots between a lower and an upper limit value. The carrier device has a height adjustment device whose adjusting movements are controlled by a control. The harvesting head has a sensor transmitting a sensor signal to the evaluation device at least upon pivoting of the side section when a limit value has been achieved during pivoting of the side section to the middle section. The evaluation device switches upon the presence of a corresponding sensor signal into a correction mode for height adjustment of the carrier device. The evaluation device outputs an adjusting signal in the correction mode to adjust the carrier device up or down by the evaluation device according to the sensor signal.
