YIELD MAPPING SYSTEM Russian patent published in 2024 - IPC A01D41/127 

FIELD: agriculture.

SUBSTANCE: yield mapping system comprises at least one yield sensor (3) for recording parameters of the crop collected and/or processed by the agricultural machine during field operations, computing device (1) connected to at least one yield sensor (3), satellite receiver of geographical coordinates (2), sensor (4) of minimum grain level in the combine hopper, which is installed at the lower point of the hopper, and sensor (5) of the maximum grain level in the combine hopper, which is installed at the upper point of the hopper. Computing device (1) is equipped with a program which enables to calibrate data from yield sensor (3) in automatic mode, determine, according to the grain yield sensor (3), the amount of grain in the hopper and the amount of grain harvested from the corresponding section of the field, as well as fix unloading of grain mass from the combine hopper with reference to geographic coordinates.

EFFECT: system simplification is provided, binding of values of yield and unloading of grain mass from combine hopper to geographic coordinates, higher accuracy of calculation of current yield and elimination of human factor due to automatic calibration of system, correction of yield values in case of partial or complete run over of a combine on an already harvested area.
