A combine harvester includes a threshing unit for threshing picked-up crop to obtain grain, a driver assistance system, with a memory for storing data, for controlling the threshing unit, and a computing unit for processing at least the data stored in the memory. A sensor system ascertains at least a portion of the current harvesting-process state. A sensor configuration assigned to the sensor system is defined by the type and scope of operational sensors is stored or can be stored in the memory. A functional system model for at least a portion of the combine harvester is stored in the memory. The computing unit is designed to carry out an autonomous determination of a threshing-unit parameter based on the system model, and defines the system model forming a basis of the control of the threshing unit depending on the sensor configuration stored in the memory.

In one aspect, the present subject matter is directed to a system for calibrating a harvester. The system includes a yield sensor configured to detect a flow of crop material discharged from the harvester and output data indicative of a flow rate of the crop material, and a wireless communication device configured to receive a transport vehicle communication from a transport vehicle. The transport vehicle communication includes a weight of a crop material in a transport receptacle. The system also includes a computing system in data communication with the wireless communication device. The computing system is configured to determine a time rate of change of the weight and is further configured to determine a yield sensor calibration update based on a time delay determination between the flow rate of the crop materials and the time rate of change of the weight.

One or more techniques and/or systems are disclosed for automating the collection aggregation, and processing of data relating to harvesting or dispersion of an agricultural product. During harvesting and planting operations, data related to the product harvested or planted can be collected, aggregated, and used to improve the operation, and to help identification of the product at point of sale or point of dispersion. Further, certain operations can be automated during the harvesting or planting, such as automatic deployment of a field cart to offload/load product from/to the agricultural vehicle in the field. Additionally, load data can be automatically collected, aggregated, and identified, to follow the product through all stages.

A yield model generates a yield map for an agricultural field. A measurement system generates measured indicators that are a measurement or quantification of crop yield in the agricultural field. An observation system generates observed indicators that are spatial agricultural datasets describing observed characteristics of the agricultural field. To generate the yield map, the yield model generates a field array representing the agricultural field. The yield model generates an input array and a yield array by mapping the observed indicators and measured indicators to cells of the field array, respectively. The yield model determines a yield value for each cell of the yield array not including a mapped indicator using information included in the corresponding cells of the input array. The yield model generates a yield map using the determined yield values and the yield values in the yield array.

A combine that can accurately measure the weight of grain retained in a grain tank is provided. When a weight measurement signal is output from a measurement switch 66, a weight measurement decision unit 75 instructs a working state determination unit 71 to perform working state determination. If it is determined that the combine is in the working state, the weight measurement decision unit 75 does not instruct a load cell 39 to perform weight measurement.

A delivery device is located at an inlet side of the cleaning shoe in a combine harvester. The delivery device is controlled in order to control a feed rate of grain that is fed to the cleaning shoe. One or more controllable subsystems are controlled based upon the feed rate.

A grain harvesting articulated combine includes a forward crop processing power unit (PPU), a rear grain cart, and an articulation joint that connects the PPU with the rear grain cart. The articulation joint includes a grain auger assembly running from the PPU to the rear grain cart for transferring clean grain from the PPU to the rear grain cart and has a forward end at the PPU and a rear end adjacent to the rear grain cart. The grain auger assembly is housed within a tube with a rotating auger housed therein. A grain yield sensor is carried by the rear grain cart and is located adjacent and to and beside the grain auger assembly wherein the auger housed therewithin throws grain against the grain yield sensor. The auger is terminated by a rotating paddle assembly that throws the grain against the grain yield sensor.

A harvester includes a measuring device for detecting a grain number of a crop flow, in which a sensor of the measuring device detects via a measuring signal kernels impacting an impact surface of the measuring device, and a processing unit of the measuring device is arranged to detect and calculate the grain number by using the measuring signal, wherein the rising edges of the measuring signal are recorded and form a measurement for the grain number. Furthermore, the measuring device for detecting a grain number and method for detecting a grain number are also provided.

Apparatus, systems and methods are provided for monitoring yield while harvesting grain. Grain released from paddles on the clean grain elevator chain of a harvester contacts a flow sensor which reports the rate of grain flow through the clean grain elevator. In some embodiments a brush is mounted to the chain and disposed to clean the flow sensor surface. In other embodiments a bucket mounted to the clean grain elevator chain releases grain against the flow sensor at a rate dependent on a grain property.

A method of estimating the mass of crop entering into a grain tank on a harvesting machine, comprising the steps of mounting a load sensor on the upper bearing of a conveyor belt moving crop through the clean grain elevator into the grain tank, connecting the load sensor to a processor, using the load sensor to measure a load on the conveyor belt when no crop is present in the clean grain elevator, and also when crop is moving through the clean grain elevator, and comparing the load with no crop present to the load when crop is present to estimate the mass of crop moving through the clean grain elevator.
