摘要： A method and an apparatus for separating a crop flow on at least one conveying and cleaning unit, particularly a top sieve, of a combine harvester, wherein the conveying and cleaning unit is excited to a longitudinal oscillation and a transverse oscillation. The transverse oscillation is controlled depending on at least one state, wherein least one state for controlling the transverse oscillation is the inclination of the combine harvester, wherein at least one further state for controlling the transverse oscillation is the grain purity, particularly the grain purity of a main crop flow. The transverse oscillation is pre-controlled depending on the inclination of the combine harvester and fine-tuned depending on the grain purity.

摘要： A self-propelled combine harvester has at least one tilting mechanism for the uniform distribution of a harvested material on an oscillating conveying and cleaning unit, in particular a top sieve. The tilting mechanism has elements for defining a swiveling direction of the conveying and cleaning unit which are arranged between the conveying and cleaning unit and a machine housing. The tilting mechanism has an actuator for continuous adjustment of at least one component part of the elements from an initial position to an adjusting position. The position of the at least one component part decisively defines the swiveling direction. An electric control unit controls the actuator depending on a state of the combine harvester and/or harvested material and the initial position of the at least one component part of the tilting mechanism.

摘要： A device for tensioning a tension mechanism of a conveying device includes a number of feeder aids extending between a drive wheel and at least one guide wheel. At least one hydraulic cylinder (including a hydraulic piston) adjusts a wheel center distance between the at least one guide wheel and the drive wheel in order to change the tension of the tension mechanism. The at least one hydraulic cylinder acts directly on the guide wheel. In order to tension the tension mechanism, the hydraulic piston is displaceably disposed in a pressure chamber and acted upon by pressure medium from a pressure source via a check valve that opens toward the pressure chamber. Once a blocked state of the check valve is reached, the pressure chamber is connected to a device for receiving a defined volume of pressure medium.

摘要： A combine harvester has a chopping mechanism and a spreading mechanism. The spreading mechanism is disposed downstream of the chopping mechanism, mechanically driven by a drive train and includes at least two rotors. The drive train of the spreading mechanism has a belt drive engageable by a clutch and configured to drive a first transmission stage via an output shaft, at least one second transmission stage drivably connected to the first transmission stage by a shaft and a braking device. The first and second transmission stages each have an output shaft for driving one or each of the rotors.
