THRESHING CONTROL SYSTEM

A method is provided for controlling a threshing system for an agricultural harvester. The method includes using a camera for obtaining images of a crop flow, processing the obtained images and controlling an operational setting of the threshing system. The images are obtained downstream of the threshing system, preferably somewhere between the threshing rotor or threshing drum and the residue spreader. The image processing aims at detecting grain ears in the obtained images, and to derive from those images at least one physical property of the detected grain ears. The operational setting of the threshing system are controlled in dependence of the derived at least one physical property.

CONTROL OF RESIDUE SPREAD PATTERN BY CONTINUOUSLY VARYING DISTRIBUTION FREQUENCY
20230076080 · 2023-03-09 ·

An embodiment includes a combine having a feeder housing for receiving harvested crop, a separating system for threshing the harvested crop to separate grain from residue, a residue spreader wheel spinning for expelling the residue from the combine, and a controller that controls the combine. The controller is configured to control the residue spreader wheel to continuously oscillate between a first speed less than a nominal speed and a second speed greater than the nominal speed while spreading the residue.

Agricultural working machine

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.

Method for operating a combine harvester with belt drive configured to implement a measure to prevent slip of the belt drive and communicate the measure to an operator

A method for operating a combine harvester configured with a number of working assemblies driven by at least one belt drive, and a ground drive, wherein the at least one belt drive and the ground drive are driven by a main drive comprising an engine, monitors for and accommodates slip. The working assemblies are monitored by sensors with respect to an occurrence of slip in the at least one belt drive. Signals representing slip are transmitted to a control device. The control device is connected to an input/output. The signals representing the slip are evaluated by the control device and the result is weighted. Depending on the weighting of the result, at least one measure is initiated by the control device, which results in a reduction of the slip and the at least one initiated measure is signalled by the input/output unit.

MONITORING VIBRATIONS IN AGRICULTURAL HARVESTERS
20220304239 · 2022-09-29 ·

A method for determining a vibration pattern in a crop processing section of an agricultural harvester. The method may start with bringing the crop processing section into a predetermined pseudo-operational configuration. When in the predetermined pseudo-operational configuration, a plurality of vibration sensors is used to establish a reference vibration pattern. The established reference vibration pattern is then stored in a memory. Analysis of the reference vibration pattern may provide useful information about a current mechanical status of moving as well as stationary parts. Vibration patterns of many agricultural harvesters may be gathered in a cloud and processed using AI tools.

INTELLIGENT POWER ALLOCATION SYSTEMS ONBOARD HYBRID COMBINES AND ASSOCIATED METHODS

Embodiments of an intelligent power allocation system include a ground traction undercarriage controllable to propel a hybrid combine over terrain, a separator device configured to separate grain from other crop material ingested by the hybrid combine, a mechanical powertrain including an internal combustion engine, and an electric drive subsystem containing a rechargeable battery pack and a motor/generator (M/G). A controller architecture is configured to monitor a current separator load placed on the hybrid combine when driving movement of the separator device during active harvesting. The controller architecture further selectively places the intelligent power allocation system in a separator power splitting mode in which the M/G and the internal combustion engine concurrently drive movement of the separator device based, at least in part, on whether the current separator load exceeds an upper load threshold.

Combine harvester

A combine harvester has a threshing unit for threshing picked-up crop to obtain grain and a driver assistance system for controlling the threshing unit. The driver assistance system includes a memory for storing data and a computing unit for processing the data stored in the memory. The threshing unit, together with the driver assistance system, forms an automated threshing unit, in that a plurality of selectable harvesting-process strategies is stored in the memory and in that, in order to implement the particular selected harvesting-process strategy, the computing device autonomously determines at least one machine parameter, for example, a threshing-unit parameter, and specifies the parameter to the threshing unit.
