The invention relates to agricultural machinery, in particular to tools for cutting in soil cracks and education in her loosened cavities.Known working body of crotonates, including drainer consisting of composite conical front part made with the possibility of axial movement, a cylindrical body with a rear cover connected through a spring to the front of tenera.However, the known working body does not allow you to regulate the water-air regime of soil, since the passage of tenera through dense soil layers is formed densified wall molehills, which prevents air and moisture exchange. This is especially true on clay soils.This is achieved by the fact that on the back cover by means of a washer with lugs pivotally mounted knives, kinematically connected by rods with movable spring support. Knives destroy reinforced wall drains the deeper, thicker walls, thereby increasing moisture and improving water distribution across the entire circumference of molehills.A comparison of the proposed technical solutions to the prototype allows to establish its compliance with the criterion of "novelty". The study of other known technical solutions in this field of technology features that distinguish the invention from the prototype, were not identified and therefore they provide the claimed technical solution according to the criterion of "significant differences".In Fig.1 shows the working body for laying drains, General view; Fig.2 - section a-a in Fig.1; Fig.3 - section b-B in Fig.1.Screed for laying mole drains includes drainer, consisting of the front cone portion 1, a cylindrical body 2, the rear cover 3, which by means of a washer with eyelets 4 pivotally mounted knives 5. Knives 5 kinematically connected by means of rods 6 with the movable spring support 7. Bearing 7 is rigidly connected with the spring 8.
FIELD: land-reclamation, particularly drainage building in flooded irrigated lands.
SUBSTANCE: method involves digging out channel in a single drainage machine pass by plow-type ditcher; dumping dug out fertile ground on channel brows in banks; digging out trench by operative tool of drainage machine; laying drainage pipe and covering thereof with ground; filling channel with fertile ground. Fertile ground layer is loosened before trench digging out along drainage pipe laying axis, wherein width of loosened ground strip is not less than operative tool width. Loosened ground is laid on channel brows. Trench is dug out by chain operative tool of narrow drainage machine performing reverse rotation and extracted ground is placed between trench walls and drainage machine bunker to cover drainage pipe moved into trench by guiding means. Trench is backfilled with ground with the use of two pairs of banks, which provides successive filling trench with ground and loosened fertile ground.
EFFECT: increased efficiency due to prevention of trench wall compaction, reduced power inputs.
SUBSTANCE: device comprises a vertical blade 1 with two wings 2 having cutting edges and cartridges 3. The vertical blade is equipped with an additional cartridge 4, firmly fixed in the base of the blade 1. The cartridges are made in the form of the cylinders truncated in front part with bevels directed upwards, and are rigidly fixed to the wings. The mole plow wings are mounted symmetrically to the blade vertical axis and directed upwards relative to the horizontal axis of the blade at an angle γ=12°-35°. The water-air regime of soil is improved, the surface flow is accelerated, the resistance to siltation and erosion of mole drains is increased, the ground water level is lowered, and the process of desalination of heavy soils is accelerates during the wash.
EFFECT: long and reliable operation of mole drainage.
SUBSTANCE: undercover soil ripper comprises milling chisel plough knife with a rack (2) and a hollow mole blade. Inside the mole blade on the shaft (6) the thrust bearings (7) are mounted. The shaft (6) is connected through the connecting insert (12) to the soil disrupter (15) in the form of a conical spring. The connecting insert (12) has left-handed threaded recesses. The housing of the hollow mole blade with the thread on both ends is cut horizontally lengthwise in half. The halves (3, 4) of the mole blade are welded to the milling chisel plough and covered by the expansion head (8) and a nut (9) with the sealing ring (10). The side slits of the mole blade housing are sealed with flat gaskets in the form of an I-beam. The spring of the disrupter in the front part is made in the form of a cylinder in the middle part in the form of a cone with the angle of expansion α=15…25°, in the rear part in the form of the rotation paraboloid y=xn, where n=0.5…0.7. The cross-section of the spring in the working part is made in the form of a wedge with an angle of inclination to the axis of the spring wire β=10…20°. The working face of the spring is coated with a layer of wear-resistant material.
EFFECT: ensuring quick assembly and disassembly of the mole blade and intensive quality soil crumbling.

SUBSTANCE: paraplough-aerator comprises a frame, a suction pipe with a safety spring, and a paraplough. The paraplough is rigidly attached to the suction pipe. The pipe at the lower part of the horizontal plane the spring with the stops is attached. The spring with the stops has the ability of stretching, compression and bending in the course of work and in deformation to saturate the soil with air by sucking air from the suction pipe.
EFFECT: device enables to increase water-permeability of soil, to saturate the soil with air, which thereby increases the crop yield.
SUBSTANCE: description of the soil horizons is provided with identification of degree of their gleization, samples are prepared of natural soils over horizons using the cut cylinder with small volume. Method differs in that using samples density of dry mass of soil is determined, after this work completion, and samples destruction - selection of the mixed soil sample and determination of its grain-size classification, according to ratio of content in fine soil of the particles with size exceeding dust, i.e. over 0.05 mm, to density of the soil at the pre-plotted calibration diagram the average geometric value of the filtration coefficient of p% probability of decreasing over the soil horizons considering degree of their gleization is estimated.
EFFECT: reduced R&D expenses, more rational use of funds for lands reclamation, operation of reclamation systems and use of reclaimed lands.
