摘要：
FIELD: agriculture.SUBSTANCE: invention relates to the field of agricultural machinery industry, namely, to machines with an auger feed for discriminatory application of mineral fertilisers. The device comprises a tank with a metering unit in its lower part, in which the spiral is mounted across the movement, which is in a cylindrical casing with a seeding spiral opening. It also comprises a metering unit position sensor, two sensors of seeding located below the seeding opening in different parts of the casing, the control unit, the navigation system, actuators of position control of the metering unit and the casing, as well as the control circuits of the actuators. During the device operation, the current fertiliser application rate determined by the metering unit position sensor is compared to the required rate determined on the basis of agrochemical field map laid in the control unit and according to the result of comparison the metering unit position is adjusted. Simultaneously, the rates of fertiliser application from the sensors of seeding, mounted in the supply and the peripheral parts of the casing, are compared with each other and with the required rate, and according to the result of comparison by turning and twisting of the casing the seeding opening location is adjusted.EFFECT: invention enables to enhance the uniformity of sowing and to eliminate time consumption for adjustment, regulation and control of the seeding rate.6 dwgИзобретение относится к области сельскохозяйственного машиностроения, а именно к машинам со шнековым высевающим аппаратом для дифференцированного внесения минеральных удобрений.
