A new design of a pneumatic sowing device operating at an excess pressure of the air flow is proposed, which allows sowing the seeds of two different crops simultaneously in one row in a combined way, placing them at equal intervals in a row and at different depths, as well as sowing in a dotted way. The new sowing disc of a dosing device is made in the form of a plate and is equipped with two rings rigidly fixed on it with the possibility of removal. The optimum thickness of the disc is 3...4 mm, the width of the ring is 11...12 mm. These parameters are established based on the size of the seeds of the sown crops, affecting the parameters of the conical cells of the rings. The manufacture of a metering disc from a polymeric material reduces the consumption of metal on the metering apparatus as a whole and reduces its mass. The use of a new resource-saving metering device allows high-quality sowing of seeds of two row crops in one area at no additional cost, while minimizing damage to seeds to a minimum. The developed pneumatic metering device with a universal dosing device has a simpler design adapted to production conditions and is convenient in operation
