Abstract: A threshing concave for a combine harvester comprises a crop processing device which is arranged at the inlet to the threshing concave and can be adjusted between an active and an inactive position, adjustable elements which are arranged downstream of the inlet to the threshing concave and can be adjusted between an active and an inactive position, and an adjustment mechanism for separate adjustment of the crop processing device and the adjustable elements, which comprises a movable adjustment element which is coupled to the crop processing device and to the adjustable elements.

Abstract: A sensor arrangement for detecting grains in a material stream that contains grains and non-grain components in a combine harvester (10) may include a conveying device. The conveying device may include an inlet and an outlet (74). A material stream may be formed in response to a rotating movement in the conveying device. The sensor arrangement may also include an electro-optical sensor arranged on the outer circumference of the conveying device and configured to view the material stream. The sensor arrangement may also include an electronic processing device for detecting grains in the material stream by using the signal from the electro-optical sensor. The electro-optical sensor may be arranged in the downstream region of the conveying device.

Abstract: A sensor arrangement for detecting grains in a material stream containing grains and non-grain components in a combine harvester may include a sampling device configured to collect a sample from the material stream; a separation device configured to separate the sample into grains and non-grain constituents; and a sensor system configured to sense the grains separated from the non-grain constituents.

Abstract: A sensor arrangement for a combine harvester that includes a conveyor for grain-containing crops. The conveyor can be set in a periodic movement by a drive. The sensor arrangement includes a baffle plate sensor associated with the conveyor and configured to emit an electrical signal in response to an impact of a grain. The sensor arrangement includes an evaluation circuit which is connected to the baffle plate sensor for signal transmission. The evaluation circuit is configured to process the signal generated by the baffle plate sensor and, taking into account the respective position of the conveyor along movement of the conveyor, to recognize a signal generated by a grain and to emit a corresponding output signal.

Abstract: 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.

Abstract: 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.

Abstract: A spreader of a combine for conveying crop residue rearwardly from a rotor assembly includes a frame coupled to the combine and has a top portion adapted to receive a portion of crop residue during a harvesting operation. An impellor includes one or more blades for rotatably conveying crop residue rearwardly, and an actuator is controllably moved between an extended position and a retracted position. The actuator is pivotally coupled to the combine. A linkage assembly is pivotally coupled to the actuator at one end and to the frame at another end. The spreader is disposable in a first position when the actuator is in the extended position, and the spreader is disposable in a second position when the actuator is in the retracted position. A movement from the extended position to the retracted position induces pivotal movement of the spreader from the first position to the second position.

Abstract: A combine double-decker crop residue spreader for use with a rotating chopper having chopper blades and through which air is blown may include a divider panel separating a lower portion from an upper portion of the spreader. The divider panel extends rearwardly from a location where the chopper blades transition from rotating towards the divider panel to rotating away from the divider. An airflow conduit extends above the divider panel in the upper portion to rearwardly direct air flow. At least one lower vertical panel below the divider panel in the lower portion rearwardly directs crop residue.

Abstract: A residue deflector is disposed in a combine body, and positioned along an airflow path to guide residue from an exit end of a cleaning shoe and a threshing and separation assembly, to a residue chopper. The deflector is configured with a plurality of spaced fingers so that air can pass through the deflector between the fingers.
