摘要：
The invention relates to the field of agricultural machinery, in particular to seeders universal pneumatic trailer and intended for drill seeding with a distance between rows of 125 mm light, medium and heavy soils grain srednesemennyh, vegetable, herb and grass mixtures with simultaneous application of fertilizer starting dose.The technical result is to reduce the complexity of services, improve the agronomic performance of crop, increase the accuracy of seeding rate and reliability of the seed drill work.The technical result is achieved in that the drill, which comprises a hopper, a single transporting system, sowing machines, openers, fan-driven, the chassis with supporting pneumatic wheels, markers, hydraulic system parameters sowing operation control system, switchgear single conveying system fitted the outside of the sidewalls of the hopper over the support pneumatic wheels. feeder sown materials into a single transport system attached to the discharge windows sowing apparatuses and constitute the housing. The lower housing portion horizontally arranged converging tube and diffuser. Also sown feed materials reclining apparatus provided with spring covers and lids with connections for receiving the second type of seed material. Planting unit for a seeding of a second type of seed material is provided with a flow divider.Technical results are also achieved by the fact that the drill is provided with depth regulating seed placement device which consists of a stack of plates is pivotally mounted, engaging with the cylinder rod and the fixed support, which is connected to the PTO shaft of the tractor. On the axis of rods of hydraulic cylinders of the side frames are pivotally mounted stops.The support wheels are mounted on the pneumatic suspensions, each of which is hinged on the individual axes, which ensures reliable operation of the drill. The marker consists of two arms and is adapted to transformation at right angles, to reduce the dimensions planter during tr
