FIELD: agriculture.SUBSTANCE: invention relates to agricultural machine building. Automatic system for monitoring and controlling settings of working members of threshing-separating device consists of unit for indicating quality of cereal crops fraction, amplifier of generator, piezoelectric quality sensors of cereal crops fraction, control unit with second driver, fan, hydraulic cylinder of variator and hydraulic control valve with electromagnetic control. Piezoelectric sensors quality of cereal crops fraction are arranged behind lower cleaning sieve and behind after threshing device. To adjustment of working elements automatic control and monitoring system second setting device and threshing drum speed transducer are additionally connected. Second setting device monitors and controls threshing drum speed using threshing drum variator hydraulic cylinder by means of threshing drum hydraulic control valve with electromagnetic control. Actual values of threshing drum speed come from rotation frequency sensor to control unit.EFFECT: system provides automation of threshing drum speed control.1 cl, 2 dwg |
