AUTOMATIC SYSTEM FOR MONITORING AND MANAGING THE SETTINGS OF THE WORKING BODIES OF THE THRESHING AND SEPARATING DEVICE Russian patent published in 2023 - IPC A01D41/127 

FIELD: agricultural engineering.

SUBSTANCE: invention relates to machines for harvesting grain crops. The automatic system consists of grain fraction quality piezoelectric sensors 1 and 2, amplifier-shaper 3, grain fraction quality indication unit 4, control unit 5 with actuators 6, 7, 8 and 9, hydraulic valves with electromagnetic control 10 and 11, concave power drive 12 , lower sieve adjustment power drive 13, fan variator hydraulic cylinder 14 and threshing drum variator hydraulic cylinder 15, concave power drive rod 16, lower sieve adjustment power drive rod 17, fan 18, threshing drum 19, concave 20, lower sieve combs 21, frequency sensor fan rotation 22, threshing drum speed sensor 23, concave position sensors 24 and lower sieve comb position sensor 25. The gap between the combs of the lower sieve varies in the range set on the fourth setting device, depending on the operating conditions of the combine harvester. The fourth setting device, the lower sieve adjustment power drive, the lower sieve combs and the lower sieve combs position sensor are electrically connected, and the lower sieve adjustment power drive, the lower sieve adjustment power drive rod and the lower sieve combs are mechanically connected.

EFFECT: expanded range of adjustment of the working bodies of the combine harvester.
