AUTOMATIC SYSTEM OF MONITORING AND CONTROL OF FAN ROTOR SPEED

摘要

FIELD: agriculture.SUBSTANCE: automatic system of monitoring and control of fan rotor speed comprises a unit of quality indication of spike fraction, an amplifier-shaper, and piezoelectric sensors of spike fraction behind the lower sieve of cleaning and finish threshing device. The system is additionally connected to the control unit with the setting device, which jointly monitor and control the fan rotor speed by the hydraulic cylinder of the fan variator by hydraulic distribution valve with solenoid actuation and the sensor of fan rotor speed. The value of the actual fan rotor speed comes from the sensor of fan rotor speed to the control unit.EFFECT: increase in the efficiency of the combine operation.2 dwg
