摘要：
FIELD: agriculture.SUBSTANCE: device comprises an encoder, a module of frequency input, a control unit. The latter is made in the form of a controller of the technological process control of sowing with flash memory, a terminal of operator control. The device also comprises a discrete output module for RS-485 interface connected to the controller and the discrete outputs with the frequency divider of setting the division factor of the frequency signal from the encoder mounted on the wheel of the drill, a generator of rotation speed control of a stepper motor depending on the speed determined by the frequency signals from the encoder. The device is provided with a tapered metering device of selecting drill with a loading cylinder, a solenoid with a return spring raising-lowering of the loading cylinder, a sensor of zero angle of the metering device position and a device for movement of the cassettes. The module has a discrete input-output. The tapered metering device controlled by the stepper motor is connected to the loading cylinder and the sensor of zero angle of the metering device position connected to the discrete input of the module of discrete input-output. The loading cylinder is connected to the solenoid with the return spring, controlled from the discrete output of the same module. The device for movement of the cassettes is connected to the loading cylinder and the stepper motor controlled also from the discrete output of the module of the discrete input-output through the generator.EFFECT: improvement of performance characteristics of the drills of the 2 and 3 stages of crop variety testing of seeds by automatic control of sowing.1 dwgИзобретение относится к сельскохозяйственному машиностроению и может найти применение при оснащении селекционных посевных агрегатов II и III этапов селекционных работ.
