Abstract: A crop elevator for a combine harvester includes an ascending section and a descending section and a housing enclosing the ascending section and the descending section. The elevator further comprises an elevator loop arranged inside the housing which includes a plurality of paddles for elevating a harvested crop. The elevator also includes a weighing system configured to determine a weight of harvested crop that is present on at least one of the paddles during an ascending movement of the at least one of the paddles in the ascending section. The weighing system includes a weight sensor configured to output a weight signal representative of the weight of the harvested crop. The ascending section of the elevator comprises a measurement section, wherein the weighing system is configured to retrieve the weight signal when the at least one of the paddles is in the measurement section of the elevator.

Abstract: A system and a method are provided for controlling a combine harvester. The method includes the steps of: receiving grain flow sensor signals from a plurality of grain flow sensors; based on the received grain flow sensor signals, determining a current load on a straw walker section; and based on the current load, adjusting an aggressiveness setting of a threshing and separation section of the combine harvester. The grain flow sensors are provided underneath and adjacent to a crop transfer surface of the straw walker section of the combine harvester and are distributed over a length of the straw walker section.

Abstract: A grain mass flow sensor assembly of an agricultural harvester has a continuously curved sensor plate positioned to receive a grain flow from an exit of the grain elevator. The continuously curved sensor plate is configured to change the direction of the grain flow in order to generate a reaction force for measuring the grain mass flow rate of the grain flow. The continuously curved sensor plate is attached to a sensor plate to load cell mounting bracket. The sensor plate to load cell mounting bracket is attached to a single point load cell torque or moment compensated force transducer at a single mounting point. The single point load cell torque or moment compensated force transducer produces a mass flow sensor signal that is proportionate to the grain mass flow rate.

Abstract: 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.

Abstract: A combine harvester has a driving shoe arrangement. The driving shoe includes a preparation pan and one or more sieves, coupled to a drive mechanism for driving a reciprocating movement of the pan and sieves. The stroke of the reciprocating movement of the pan and/or sieves is adjustable, through the application of a drive mechanism including one or more pivotably mounted support arms for supporting the pan or sieve, and a drive arm connected to one of the support arms through an adjustable connection link. The adjustable connection link can be a variable length actuator whose length determines the stroke of the pan or sieve. The stroke of the pan or sieve can be adjusted during a harvesting run, thereby allowing a fast adjustment to changing external conditions such as the slope of the terrain.
