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.

Cleaning device in a combine harvester

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.

Tilting mechanism for uniform distribution of a material on a conveying and cleaning unit

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.

Combine harvester comprising a chopping mechanism

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.

An agricultural harvesting machine, in particular a self-propelled forage harvester for picking up and processing crop material has a transfer device&#x2014;which is located downstream from feeder and chopping devices and is swivelable around a horizontal and vertical axis&#x2014;for transferring the crop material, and at least one dampening device&#x2014;which is located between the vehicle body and the transfer device&#x2014;for dampening the vibrations of the transfer device. The dampening device may be adjusted as a function of specified operating criteria in order to dampen the vibrations of the transfer device.

Agricultural harvesting machine with transfer device

A hydraulic system for an agricultural working machine composed of a carrier vehicle and at least one adapting device has one or more hydraulically driven consumer included in each of the carrier vehicle and the at least one adapting device, and a common hydraulic pressure line, wherein the consumers are connected to the common hydraulic pressure line, and a constant hydraulic pressure is applied to the common hydraulic pressure line.

Hydraulic system for a self-propelled harvesting machine

For operating a self propelling harvester provided with a cutterbar and a chopping and distributing device located in a discharge region and supplying a crop stream to at least one ejecting blower, a discharge direction of the crop stream from the ejecting blower is adjusted by a breaking edge which is longitudinally displaceable by a drive, wherein the drive for adjusting the at least one breaking edge is regulated depending on the working width of the cutterbar and/or depending on the distribution of the crop stream on the ground, to adapt the scattering width automatically to the working width of the cutterbar and to distribute in a uniform layer density on the ground.

Method of operating a self-propelling apparatus

An agricultural working machine has intake conveyor mechanisms, a hydraulic circuit via which the intake conveyor mechanisms are hydraulically driven and including at least one hydraulic motor which drives the intake conveyor mechanisms, at least one switching valve system for interrupting or releasing a flow of hydraulic oil being assigned to the at least one hydraulic motor, the switching valve system being configured for interrupting or releasing the flow of hydraulic oil to the hydraulic motor as a function of a signal from a foreign-object position detection device, the switching valve system including at least one braking function for the at least one hydraulic motor, and a section of the hydraulic circuit which realizes the at least one braking function is essentially free of elasticities.

Chopping and distributing device

A hydraulic reel drive wherein the reel motor is driven by a hydraulic pump, which is adjustable in a continuous manner and operates therewith in a closed oil circulating system. The advantage of this arrangement is that the reel always rotates uniformly independently of the instantaneous load thereon. Another advantage thereof is that by using a hydraulic pump, which is adjustable in a continuous manner, only that amount of oil is ever circulated as is required to drive the reel at a predetermined rotational speed.

The present invention relates generally to agricultural machinery and, more particularly, to a device for controlling a double-acting steering cylinder of a steering system, having two working connections of the steering cylinder, wherein the working connections are each connected by means of an input pipe or an output pipe to a valve unit, which comprises two switching valves that can be moved alternately into a first switching position and into a second switching position and the steering cylinder in the first switching position of the first switching valve admits a fluid at the first working connection and the steering cylinder in the second switching position of the second switching valve admits the fluid at the second working connection.

Control device for a steering system

The invention concerns a method and an apparatus for ejecting a material, in particular a straw material, having a pivot unit comprising an impeller blower, a cooperating fluid cylinder, with a control unit comprising at least one directional control valve for control of the fluid cylinder so that at least one ejection nozzle of the impeller blower can be pivoted reciprocally. The control unit further comprises a pressure control valve. An electrical control device is provided, which acts on the pressure control valve and/or the directional control valve in such a way that a piston of the fluid cylinder essentially performs a harmonic reciprocating movement.
