AUTOMATIC SYSTEM FOR MONITORING AND MANAGING THE SETTINGS OF THE WORKING BODIES OF THE THRESHING AND SEPARATING DEVICE Russian patent published in 2022 - IPC A01D41/127 

FIELD: agricultural engineering.

SUBSTANCE: invention relates to agricultural engineering, and in particular to machines for harvesting grain crops. The automatic system for monitoring and managing the settings of the working bodies contains an indication unit 4 for the quality of the head fraction, an amplifier-shaper 3 and piezoelectric sensors 1 and 2 for the quality of the head fraction, a control unit 5 with setting devices 6, 7, 8 and 9. The first setting device 6 for control and fan control 18 using the hydraulic cylinder of the fan variator 14 through the hydraulic valve of the fan with electromagnetic control, the fan speed sensor 22. The second master device for controlling and monitoring the speed of the threshing drum 19 using the hydraulic cylinder of the variator of the threshing drum 15 through the hydraulic distributor of the threshing drum with electromagnetic control, threshing drum speed sensor 23. The third setting device for controlling and monitoring the concave power drive 12 by means of the concave power drive rod 16, concave, concave position sensors 24. The fourth setting device for controlling and controlling the power drive for adjusting the upper sieve 13 through the rod of the power drive for adjusting the upper sieve 17, the comb of the upper sieve, the position sensor of the combs of the upper sieve. In this case, the fourth setting device is made in the form of a regulator of the range of the gap between the combs of the upper sieve 21, and the position sensor of the combs of the upper sieve 25 is made in the form of an inductive sensor. The fourth setting device, the upper sieve adjustment power drive, the upper sieve combs and the upper sieve combs position sensor can be electrically connected, and the upper sieve adjustment power drive, the upper sieve adjustment power drive and the upper sieve combs can be mechanically connected.

EFFECT: device provides the ability to adjust the gap between the combs of the upper sieve of the combine harvester.
