摘要:
A separating device formed with rotationally driven components and stationary components has at least one crop-treatment element for processing crop. The crop-treatment element extends transversely to the rotational direction (R) of the components, at least in sections. The crop-treatment element has a substantially cuboid cross-section and a front edge with a curved course optimized in terms of flow, and which faces a rotational direction (R) and away from a conveyance direction (FR) of the crop.

A device for coordinating a first vehicle with a transfer device and a second vehicle with a loading chamber that is filled by the transfer device includes a monitoring device for monitoring the transfer from the first vehicle to the second vehicle and a control unit. The control unit relies on the monitoring device to detect a position of an impact point of a load crop stream discharged from a transfer device of the first vehicle to the second vehicle and, in the event the detected position deviates from a target position, the control device sets the ground-speed differential to be different from zero until the detected position matches the target position.

In vehicles designed to pick up and process crops, drive units affect the ground drive, which is an all-wheel drive, which acts on all of the wheels and/or track roller unit in contact with the ground, electronic controls and actuators perform the control and regulation of the drive units, and control units that control the drive torque at the wheels are used to obtain good traction and minimal slippage of the wheels on the ground. To control the drive torques, sensors are used at particular points, the signals and data of which are processed by the control device in order to predetermine a torque or intake volume requirement. The preselection of torque in the control results in the intake volume of the hydraulic drive motor being regulated. By specifying the intake volume required, it is possible to obtain optimal traction at one or more drive wheels, and to prevent undesired slippage of any one drive wheel in advance.

A combine harvester operates with an axial separating device for separating a crop flow picked up by the combine harvester into a plurality of partial flows. A partial flow composed of grain and non-grain components is fed by a separation surface of the axial separating device to a cleaning unit disposed downstream. The axial separating device is configured to manipulate a local concentration gradient of the partial flow that is output by the axial separating device caused by a tilt of the combine harvester. The extent of the manipulation is controlled individually depending on the tilt of the combine harvester.

An agricultural harvesting machine has a measurement device for investigating a crop flow conveyed through the harvesting machine. The measurement device includes at least one optical detection unit disposed at the crop flow for detecting light reflected by the crop and an evaluation unit for evaluating the spectrum of the detected light in order to derive properties of the crop. The evaluation unit is disposed at a position of the harvesting machine that is decoupled from mechanical loading by the crop flow to the greatest extent possible and is connected to the detection unit by way of at least one optical waveguide.

A combine harvester includes a first discharge mechanism having a changeable discharge direction, a chopping assembly for chopping up straw and a second discharge mechanism disposed downstream of the chopping assembly. The second discharge mechanism disposed is operated at least two different positions. In a first position, the second discharge mechanism is supplied with crop from the chopping assembly and the first discharge mechanism. In a second position, the second discharge mechanism disposed permits crop to be discharged upon bypassing the second discharge mechanism. The discharge direction of the first discharge mechanism is dependent upon the operating state of the chopping assembly.

A server system for the administration of sequences for agricultural working machines made up of parameterized process steps of working devices includes a server and database in which a sequence inventory of sequences is stored. Sequence identifiers are assigned to each of the sequences of the sequence inventory, which describe one or more process steps of the respective sequence. A network interface to a global communication network is included to receive connection requests from a client and establish a connection-oriented, bidirectional data channel between the server and the client. The server receives a selection criterium from the client via the data channel, determines a sequence from the sequence inventory on the basis of a comparison of the selection criterium with the sequence identifiers and transmits the determined sequence to the client via the data channel.

A drive system embodied as belt drives of a self-propelled combine harvester includes, on one machine side of the combine harvester, a main drive pulley. The main drive pulley is driven by an internal combustion engine. Proceeding from the main drive pulley, a device for separating out residual grain and a straw chopper are driven via a first intermediate drive stage. A functionally reliable drive of the device for separating out residual grain, the straw chopper and powerful front harvesting attachments and a high power density combined with limited installation space is ensured by use of the drive system.

A method for unloading crop stored in a grain tank of a self-propelled combine harvester into a drivable collecting container equipped with a drive unit includes positioning the collecting container relative to the combine harvester and moving the collecting container parallel thereto while the crop is fed to the collecting container directly or indirectly by way of a grain tank discharge pipe equipped with an outlet chute, simultaneously with the harvesting operation.
摘要:
An electronic control and display unit comprises a display and at least one control unit. The display has a plurality of visualization regions and icons representing settings of parameters are assigned to the display in one or more visualization regions. A particular icon represents a parameter of a working machine. Activating the particular icon causes at least one virtual adjusting element to be shown on the display. The virtual adjusting element can be edited in order to change the parameter of the working machine.
