A sensor assembly for detecting the height of a mixture on a conveyor floor and/or a sieve of a cleaning system of a combine harvester is assembled with the combine harvester. The sensor assembly includes at least two light-sensitive sensors, positioned one above the other, and an emitter at a distance from the sensors, are attached on the upper side of the conveyor floor and/or the sieve. The sensors are configured to receive light radiated from the emitter as long as the light is not absorbed by the mixture, and the sensors are connected to an analysis device which is configured to generate an output signal representative of the height of the mixture on the basis of the output signal of the sensors.

A combine harvester having a cleaning system with at least one cleaner assembly for cleaning the harvested and a drive assembly connected to the cleaning system to drive the cleaning system, thereby driving the at least one cleaner assembly to perform a reciprocating cleaner movement. The drive assembly comprises a variable speed drive assembly with a rotary drive comprising a rotatable output shaft for driving the cleaning system, a transmission to connect the rotatable output shaft to the at least one cleaner assembly, the transmission configured to convert an angular movement of the rotatable output shaft to the reciprocating cleaner movement, and a control unit to control an angular velocity of the rotatable output shaft based on an input signal.

A conveying device of an agricultural processing machine conveys loose material along a window which is inserted into a wall. A sensor measures in a contactless manner a characteristic of the conveyed loose material. A fluid ejector ejects a fluid jet onto a surface formed in the interior of the processing machine. The fluid is thereby provided in a space between the window and the conveyed loose material.

A harvester movable along a support surface. The harvester includes an inlet configured to receive crop, a blade configured to cut the crop into billet and extraneous plant matter, and a cleaning system configured to distinguish between billet and extraneous plant matter. Billet is directed toward a conveyor configured for discharging billet to a vehicle and extraneous plant matter is directed toward a hood. The hood includes a debris director defining an outlet configured to eject extraneous plant matter as residue onto the support surface. The outlet is disposed at an angle of residue ejection with respect to the support surface. The debris director is configured to adjust the angle of residue ejection with respect to the support surface.

A control system for a harvester having a residue discharge system operable to eject crop residue according to an adjustable residue discharge parameter, the control system including a processor, a memory, a human-machine interface, and a sensor configured to detect at least one of wind speed, wind direction, or humidity. The control system is configured to receive the signal from the sensor, receive an operator input corresponding to a desired residue management strategy selected from at least a first residue management strategy and a second residue management strategy, and adjust the residue discharge parameter based on the desired residue management strategy and the detected at least one of wind speed, wind direction, or humidity.

A grain cleaning system for a combine harvester having a transmitter adapted to transmit a base signal at a known frequency and one or more spaced receivers for detecting signals of a different frequency as reflected from airborne grain and other materials within the duct of the grain cleaning system. An Electronic Control Unit modulates the base signal and the reflected signals to obtain Doppler signals or frequencies from which an average particle velocity is determined. The particle velocity is used as an input parameter for the generation of control signals for the adjustment of various working units of the combine harvester including, by way of example, the fan and sieves.

A combine harvester which regulates spreading of crop flow on the ground, with the crop flow passing through a shredding and/or a spreading device in the rear region of the combine harvester, is disclosed. The combine harvester includes a driver assistance system, which includes a computing unit and a display unit. The computing unit processes information generated by the machine's internal sensor systems, external information and information storable in the computing unit. The driver assistance system stores selectable spreading strategies to regulate the spreading of the crop flow exiting the combine harvester and one or more of the partial strategies assigned to the respective spreading strategy. The driver assistance system uses the selectable spreading strategies and the partial strategies in order to regulate the crop flow spread on the ground.

A method for automatically tuning an agricultural combine (100), comprises the steps of: receiving (304) a signal from an operator of the agricultural combine (100) indicating that current operation of the agricultural combine (100) operation is acceptable; determining (306) current performance parameters of the agricultural combine after the step of receiving; calculating (310) a performance parameter error limit for each of the current performance parameters in the step of determining; again determining (312) current performance parameters; comparing (314) the again determined current performance parameters with the performance parameter error limits to thereby determine whether one or more of the again determined current performance parameters falls outside its associated performance parameter error limit; and if at least one of the again determined current performance parameters falls outside its associated performance parameter error limit, then calculating (316) changes to machine settings of the agricultural combine (100) that will bring the at least one of the again determined current performance parameters back within its associated performance parameter error limit.

Disclosed is an articulated harvesting combine of a forward powered processing unit (PPU), a rear grain cart, and an articulation joint connecting the PPU and rear grain cart. Loss sensor pads in the straw discharge stream are graphically displaying to the operator. Articulation joint sensors rear teeth on an articulation joint arcuate beam and are used to display the degree of articulation to the operator. A jog motor permits the operator to move the feed house forwards/backwards to clear blockages. A right hand joystick and a left hand joystick provided control of all combine functions.

A combine harvester self-adaptive cleaning control apparatus, includes a return plate, a cleaning sieve, a cleaning centrifugal blower, an impurity collection and stirring auger, a grain collection and stirring auger, a cleaning grain loss monitoring sensor, a grain tank grain impurity rate automatic monitoring apparatus, and an on-line monitoring and control system. The on-line monitoring and control system is connected to the cleaning centrifugal blower, the cleaning grain loss monitoring sensor, the grain tank grain impurity rate automatic monitoring apparatus, and a power driving mechanism of a louver sieve having an adjustable opening. Also disclosed is a self-adaptive cleaning method of the cleaning apparatus which can automatically adjust various working parameters according to a working quality of a working process, improve production efficiency, control failure rate, and improve a down-time working time for the apparatus.
