AUTOMATIC SYSTEM FOR MONITORING LOAD OF FINISH THRESHING DEVICE OF COMBINE HARVESTER Russian patent published in 2024 - IPC A01D41/127 

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to agricultural machine building, namely to machines for harvesting grain crops. Result of the invention is achieved by the combine harvester finish threshing device load control system, comprising an element that generates signals, and a visual observation indicator, wherein the signal generating element includes three induction sensors mounted on the housing of the finish threshing device and fixed so that the first provides fixing the number of passes of the blades, which swing on the axes in the rotor hub seats, to the beginning of the deck, the second is the fixation of the number of passes of the rotor blades wavy cavities between the projections in the middle part of the deck, and third – fixation of number of passes of wavy cavities of rotor blades between projections at end of deck, wherein electric signals are transmitted to control unit, which compares the electrical signals from the induction sensors numerical values and outputs the results of these comparisons to the light signalling unit with the visual observation indicators in the form of turning on the green, yellow and red lights, connection between induction sensors, control unit and light signalling unit is carried out by means of electric wires.

EFFECT: possibility of controlling increased supply of heap of wheat caused by non-optimal operating modes of the cleaning system into the finish threshing device of a combine harvester.
