A detection arrangement for detecting a wear status of a chopping knife arrangement of a chopping device provided for processing a product flow, wherein the chopping device has a revolving chopping drum receiving the chopping knife arrangement and at least one shear bar which cooperates with the chopping knives, with a sensor arrangement which has a magnetic exciter arrangement and a flux conducting device magnetically coupled thereto. The sensor arrangement provides a pole arrangement which forms at least one magnetic pole with a pole surface for conducting magnetic flux, wherein at least a portion of the chopping knife passes the pole arrangement during a rotation of the chopping drum. A voltage induced when a chopping knife arrangement passes the sensor arrangement forms the measured magnetic value, which is used by the evaluation unit to determine the state of wear of the chopping knife arrangement.

Cutting sharpness detection device

A forage harvester comprising an edge sharpness detection device for detecting a degree of edge sharpness of a cutting mechanism. The cutting mechanism comminutes a stream of harvested material, with a material inflow area being defined where the cutting blades interact with the shear bar to comminute the harvested material. The edge sharpness detection device excites one or more magnetic circuits, with the respective magnetic circuit being closed by the respective cutting blade during rotation of the cutter drum once one of the cutting blades passes the magnetic assembly. The edge sharpness detection device detects the magnetic flux in the respective magnetic circuit and, based on a detected change, determines a degree of edge sharpness of the respective cutting blade. Further, the magnetic flux of the magnetic circuit may be guided lengthwise in the cutting blade at least along a longitudinal section of the respective cutting blade.

A combine harvester has at least one header for cutting plants to be harvested with the aid of the combine harvester, a feeder for conveying the cut plants in the direction of a threshing mechanism, and a threshing mechanism, with the aid of which fruits can be removed from the cut plants in such a way that the fruits are then present separately from plant residue of the plants. The feeder comprises a revolvingly driveable conveying unit and a conveyor channel within which the cut plants can be conveyed with the conveying unit. The feeder interacts with a measuring unit in the form of a sensor unit that contactlessly detects material feed height of plants conveyed with the aid of the feeder in the conveyor channel.

Combine harvester and method for the operation thereof

A method for determining a mass flow composed of bulk material, in particular grain, which is conveyed by means of a continuous, circulating conveyor, having planar conveyor elements, from a lower bulk material receiving area to a higher bulk material delivery area, in which the bulk material delivered by the conveyor is deflected by a guide surface disposed in the bulk material delivery area toward a measuring device, wherein the mass flow is determined by the measurement of a resulting force (F_G) exerted on a sensor surface of the measuring device, wherein at least two parameters having an effect on the force measurement, in particular parameters independent of bulk material properties, are compensated for. A control and regulating device for executing the method for determining a mass flow composed of bulk material is also provided.

An agricultural working machine embodying a combine harvester for processing crop includes an intake conveyor mechanism for picking up the crop, a moisture content sensor arrangement for measuring a moisture content of the picked-up crop and generating a crop moisture signal based on the measured moisture content. A throughput sensor arrangement, preferably a layer thickness sensor arrangement, determines a throughput quantity of the picked-up crop. The crop moisture content signal is corrected on a basis of the throughput quantity that is determined.

Agricultural working machine

An agricultural working machine has at least one working unit and a display device for displaying or adjusting parameters of the working machine the at least one working unit of both. The display device has a display unit with jointly depictable display elements for visualization of parameter-based values, the display elements preferably arranged concentrically in a form of circular-ring sections. The display device also includes at least one bar display that at least partially encircles the display elements radially on the outer side. Indicator element for displaying a defined value are disposed on the at least one bar display.

A harvesting system includes a self-propelled harvesting machine and a drivable collecting container equipped with a drive unit, which can be positioned relative to the harvesting machine and moved in parallel therewith. Crop is fed directly or indirectly to the collecting container during harvesting operation from the harvesting machine using a feed pipe equipped with an outlet chute. The collecting container is equipped with a device for loading it with crop in a uniform manner. The collecting container is moved in a constant position relative to the harvesting machine by way of a control device while the crop is being conveyed. The collecting container is preferably a filling device, by way of which uniform distribution of the crop in the collecting container () can be attained.

A method for controlling a crop separating process of a combine harvester with a separation device that transfers crop a cleaning device having at least one sieve with adjustable opening widths driven in an oscillating manner and a fan providing air flow upon the sieves to loosen the crop located thereon, assures that substantially three different loosening phases (F, S, W) occur during the loosening of the crop. The method determines current separation curves of the crop across a width of the cleaning device at points separated from each other in a conveyance direction (FR), evaluates the separation curves, detects the loosening phase (F, S, W) present in a conveyance direction (FR) by comparing the separation curves and initiates action depending on a detected loosening phase (F, S, W) that results in optimization of the loosening on at least one section of the cleaning device.
