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.

A header for stalk crop has a multi-part cutter bar with oscillatingly driven cutter bar parts. Cutter bar knives of the cutter bar interact with counter knives connected to header frame. A drive shaft ends in a first plane inside a gear housing arranged behind the cutter bar. An eccentric shaft supported in the gear housing carries a gear wheel arranged in a second plane above or below the first plane. The drive shaft drives the gear wheel through a bevel gear. First and second eccentric discs, arranged in third and fourth planes, respectively, are connected to the eccentric shaft; first and second eccentric levers are correlated therewith. First and second pivot levers are connected to the first and second eccentric levers and connected to stationarily supported pivot shafts. Crank arms connected to the pivot shafts, respectively, transmit their pivot movement to the cutter bar parts.

A draper platform for a combine harvester has a center section attachable to a feed channel of the combine harvester. Lateral sections are arranged laterally on opposite ends of the center section. The center section has a center frame; the lateral sections have a lateral frame and are pivotable relative to the center section about a pivot axis that is oriented in travel direction of the draper platform. A cutter bar is provided and pivotable arms having a first end connected to the cutter bar and a second end connected to the center frame or the lateral frames connect the cutter bar pivotably to the center section and the lateral sections. Drive devices are operatively connected to the cutter bar and conveying devices that convey cut stalk material. The pivotable arms are arranged such that less than one of them is present per meter of working width of the draper platform.

A combine header for a harvesting machine is provided with a frame and a cutter bar connected to a leading end of the frame. A conveying device connected to the frame conveys stalk material cut by the cutter bar. A drive device drives the cutter bar and the conveying device. First support wheels are connected to the frame at lateral ends of the combine header and support the combine header on the ground. The support wheels arranged underneath the combine header.

An agricultural cutting device has knife bar sections with section knife blades. A drive with phase offset drives the knife bar sections at least temporarily in opposite directions. The section knife blades interact scissor-like with counter knives. The knife bar sections have adjacently positioned bar ends. When the knife bar sections move, a gap of varying size is formed between the bar ends. A mowing finger is arranged at the gap. A stationary knife blade with first cutting edges is arranged at the mowing finger. The first cutting edges are arranged adjacent to the mowing finger and extend at a slant relative to a forward travel direction of the cutting device so that the cutting edges have a V-shaped arrangement broadening in travel direction. The knife bar sections have an outer knife blade attached to the bar ends whose cutting edges extend parallel to the travel direction.
