The invention relates to agricultural machinery, in particular to devices of malewane for stony soils. Known sleutel-rotovating to improve moisture-absorbing capacity of the soil (A. N. Karpenko, A. A. Zelenev, V. M. Halanski. Agricultural machine. M.: Kolos, 1976, p. 78), the working body of which is made in the form of a knife-scelerata, sunk to a depth of 40 cm and devices for craft over a slot permeable platens. The disadvantage of this working body is the low efficiency of struggle against excess moisture on the field. The closest in technical essence and the economic effect is the working body for malewane soil (patent RF №2010473), including mounted perpendicular to the frame of the knife is pivotally mounted on the back of his kratovil in which for the purpose of regulating the depth of education we work depending on the density of the soil kratovil secured to the knife by means of a spring-loaded bar that is installed with possibility of movement along the knife; a rack installed in the T-shaped groove of the knife. The disadvantage of this working body for malewane is a low functionality (because the device does not provide a smooth change in the slope of molehills) and low operational reliability (spring, T-shaped groove, which hammered the ground). Those�which aspects the object of the invention is the creation of delegates-aerator for stony soils, performing meleanie and the soil is saturated with air to increase the yield of agricultural crops. The technical result - the increase of soil fertility and, consequently, the yield of crops. The novelty of the invention is a suction pipe(2) to which in the lower part of the horizontal plane is attached serpentine spring (5) with the stops (6) capable of tensile, compressive, and buckling during deformation to saturate the soil with air through the suction air from the suction pipe. The device of delegates-aerator is shown schematically in Fig. 1. Sleutel-aerator consists of a frame (1), suction pipe (2), the safety spring (3), delegates (4), serpentine springs (5) and the abutments (6). The device operates as follows: sleutel (4) cut a slit at a certain depth. When cutting slits selvatelle, to which is attached a coil spring (5) with the stops (6), the formation of molehills in the gap. When the deformation of the serpentine spring (5) with the stops (6), contacting with stones (7) is stretched, compressed, bent, which creates a pumping effect within the soil and the air is sucked through the suction pipe (2) into the soil. The safety spring (3) when an elevates-aerator with large stones (7) performs two functions: protects the device from damage and, stretching, gripping, infinitely adjustable and�Yas, curving, nourishes additionally soil air due to the suction air from the suction pipe (2).

Sleutel-aerator for rocky soil, comprising a frame, a suction tube with safety spring and delevel, characterized in that elevating fixedly mounted suction nozzle, which in the lower part of the horizontal plane is attached to a spring with stops that have the capability of stretching, compression and bending in the process of work and strain to saturate the soil with air through the suction air from the suction pipe.
