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.

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.

A sieve for a cleaning system of an agricultural harvester includes: a sieve frame defining a top side; adjustable louvers carried by the sieve frame and defining apertures; an adjustment bar coupled to the adjustable louvers such that displacement of the adjustment bar changes a size of at least some of the apertures; and an adjustment assembly. The adjustment assembly includes: an adjustment arm coupled to the adjustment bar and pivotable relative to the sieve frame such that pivoting of the adjustment arm about a pivot axis displaces the adjustment bar. The adjustment arm carries a locking pin. A shaft is disposed on the top side and coupled to the adjustment arm. Displacement of the shaft from a first position to a second position causes a corresponding displacement of the locking pin from a locking position to an adjustment position.

A method for operating an agricultural vehicle. The method includes an initial step of providing the agricultural vehicle which includes a feeder housing and a header. The header includes at least one row unit, which has a pair of deck plates, and a deck plate adjustment system. The deck plate adjustment system includes at least one actuator connected to the deck plates, an electronic control unit operably connected to the at least one actuator, and at least one sensor. The method includes the further steps of pivoting the feeder housing to raise the header, sending, by the at least one sensor, a signal to the electronic control unit, and cycling the deck plates, by the electronic control unit actuating the at least one actuator to move the deck plates, for removing a buildup of material on the deck plates.

A combine harvester may include a chaffer to separate residue from grain in crop material, a fan to direct air through and across the chaffer to carry the residue from the harvester, a sensor to output signals indicating a characteristic of the crop material upstream of the chaffer and a controller to adjust a speed of the fan based on signals from the sensor.

An automatic uniform distribution apparatus for the threshed material from the combine harvester comprises a tangential flow threshing and separating device, a shaking plate threshed material detecting device, a shaking plate, a shaking plate flow guiding mechanism, an axial flow threshing and separating device, a chaff screw conveyor, a return plate, a return plate flow guiding mechanism, a return plate threshed material detecting device, a vibrating sieve, and an on-line detection controller. Force sensors are provided at lateral positions below discharge ports of the shaking plate and the return plate to measure flow rates of the threshed material in lateral regions of the shaking plate and the return plate.

A sensor arrangement for detecting properties of a mixture including grain and contaminants in a cleaning device of a combine harvester. The sensor arrangement is equipped with a sensor element for providing an output signal in respect of a property, detected by the sensor element, of the mixture adjacent to the sensor element. The sensor element is configured to be brought operationally continuously in succession into different positions in relation to the mixture in order to sense different points of the mixture in the different positions of the sensor element.

A multi-layer segmentation/stalk cutter device for a first season of double-crop rice and a control method, and a combine harvester for a first season of double-crop rice, the multi-layer segmentation/stalk cutter device comprising: a cutting platform, a segmenting cutter and a stalk cutter, at least one segmenting cutter being disposed at a lower rear portion of the cutting platform, the segmenting cutter being hinged on a moving chassis, and a second execution mechanism controlling the cutting height of the segmenting cutter; the stalk cutter being disposed at a lower rear portion of the segmenting cutter, the stalk cutter being hinged on the moving chassis, and a third execution mechanism controlling the cutting height of the stalk cutter.

A graphical user interface (60) for a combine harvester (10) includes, in a first portion (62) of the user interface, a graphical representation (66, 70) of an amount of material passing through a threshing system (22) at multiple positions along a longitudinal direction of the combine harvester, and a graphical representation (68, 72) of an amount of material passing through a cleaning system (42) at multiple positions along the longitudinal direction of the combine harvester. The user interface further includes, in a second portion (64) of the user interface, a graphical representation (74, 78) of an amount of material passing through the threshing system (22) at a plurality of locations along a lateral axis of the combine harvester, and a graphical representation (76, 80) of an amount of material passing through the cleaning system (42) at a plurality of locations along the lateral axis of the combine harvester.

A cleaning and tailings system of an agricultural harvester including an upper sieve and a lower sieve spaced from the upper sieve. A clean grain sheet is disposed below the lower sieve, and a tailings sheet is disposed below the clean grain sheet for receiving grain from the lower sieve and upper sieve. A tailings auger is disposed about a forward end of the tailings sheet, and a sensor is disposed about an inlet of the tailings auger for sensing impact of grain received by the tailings sheet. A controller is in communication with the sensor, wherein the controller is configured to determine an amount of grain received by the tailings sheet.
