Abstract: A draper head has a draper head frame and an attachment frame for connection to a feeder housing of a harvester. The draper head frame is connected to swing arms facing in working direction and having front ends movable vertically. The front ends of the swing arms are connected to a blade angle section provided with cutting elements. A center draper belt frame is pivotably arranged at the draper head frame and has a center draper belt disposed thereat. Transverse conveyor belts convey crop transversely to the working direction to the center draper belt which conveys crop rearwardly toward a discharge opening of the draper head. A rotary conveyor is arranged upstream of the discharge opening for conveying the crop toward the discharge opening. A rotation axis of a rearward shaft of the center draper belt and a rotation axis of the center draper belt frame are concentrically arranged.

Abstract: 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 (22) is rotatably connected to a first side (28) of a rocker lever (24) which can be rotated about an axis (26) and the second side (30) of which rotatably engages with an energy store (32) that is adjustable in length, and the frame part (6) can be moved against the force of the energy store (32) that is adjustable in length by the swinging arms (12) via a rocking movement of the rocker lever (24) about the axis (26) miming transversely to the working direction of the cutting mechanism (4) when a lifting force acts on at least one swinging arm (12).

Abstract: The present invention relates to a cutting unit (2) for attachment to the height-adjustable intake duct (6) of a harvester (4). In order to improve the sensor-supported height guidance of cutting units, it is proposed to provide at least one additional load sensor (26) which measures the load (28) with which the cutting unit (2) loads the intake duct (6), in order to calculate a height-control-relevant signal (32) from the transmitted sensor values (25) of the distance sensor (18) and the load sensor (26) via an evaluation device (24), which signal (32) is transmitted to the interface (34).

Abstract: 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.

Abstract: A cutting system for a combine harvester has a three-part frame with frame parts articulately joined with each other. A cutter bar, a reel, a central belt conveyor system, and lateral belt conveyor systems for discharging the cut stalk material are supported by the frame. The lateral belt conveyor systems move transversely to the travel direction towards the central belt conveyor system. The central belt conveyor system moves contrary to the travel direction. To prevent accumulation of crop material near the rear wall of the lateral belt conveyor systems, a three-part screw conveyor is arranged near the rear wall and extends across the operating width of the cutting system such that the length of the screw conveyor parts corresponds at least approximately to the width of the frame parts. The screw conveyor parts are powered by a joint drive. Adjacent screw conveyor parts are mutually connected by universal joints.

Abstract: A header for harvesting agricultural crop is designed to be mounted on a harvesting machine and has a support frame with a cutter bar arranged on the front side and blades fastened thereto. Conveying elements for transporting away the cut stalk material include at least two belt conveyors conveying the crop transversely relative to the travel direction and a central belt conveyor as a middle belt that conveys counter to the travel direction. A drive drives the cutter bar and the conveying elements. In order to better protect the middle belt against grain losses over the lateral edge of the revolving belt, the middle belt has, at lateral edges on its outwardly pointing surface, a grain-blocking elevation, respectively.
