FIELD: agricultural engineering. ^ SUBSTANCE: invention can be used at subsurface tilling and seeding. Proposed device has frame with connecting device and support wheels. Hopper for seeds and loose fertilizers, container for liquids fertilizers with sowing units and metering devices are mounted on frame. Posts are mounted of frame in two or three rows. Duckfoot tines and colters with guides-spreaders for seeds and loose mineral fertilizers are secured on lower ends of posts. Spring-loaded tie-rods are hinge-connected to rear part of frame. Gangs of soil-packing working members are installed in grips of tie-rods at approach angle. Said working members consist of sets of rolls mounted on axles with equal pitch and fixed on said axle. At least two soil bursting and leveling devices are secured on frame of unit being provided with spring-loaded tie-rod to regulate tilling depth. Working members of soil busting and leveling devices are made in form of steel bands with coiled free ends secured on cross beams by central part. Such design improved water accumulation and water retention and creates favorable conditions for growing and developing of crop. ^ EFFECT: increased yield and improved quality of agricultural products. ^ 4 cl, 5 dwg |
