The bit on the bottom plot is made in the form of a rod and is fixed in an inclined hole inside S. the Middle part is made in two mating curved surfaces B, forming a through hole, the front and rear sections provided with inlet support ring (wok) and the output ring (VK). Wok and VK is provided with a detachable elements (SE). SE wok can be made in the form of a cylindrical knife or the head part of tenera. SE VC made in the form of Donets tenera. 11 C.p. f-crystals, 14 ill. 3 table.

The invention relates to agriculture of molehills and aeration channels.

Known scarifier containing fixed on the frame rack with a chisel and placed at an acute angle thereto and to each other additional racks with bits, in which, to reduce the energy intensity of the tilling of soil, the leading edge of each rack is installed at an acute angle to the horizontal plane, and an additional rack mounted on the rear side of the bit of the main stand and the front flange is offset from the toe of the bit of the main rack in the opposite direction, with the axis of symmetry of each additional bit is placed in the same plane with the longitudinal axis of the additional hours.

Describes the working body can be acceptable for loosening soil with a small amount of vegetable and crop residues on the surface of the field. When loosening perennial crops, grasses and pastures of the basic and additional hours in the junction with bits hanging plant residues. This leads to complete blockage of the working body and instead of the Ripper turns out canadacomputer. Overhanging root and plant residues on three racks dramatically increase its tractive resistance. Hanging remains together with soil lead to villablino of soil and other perennial crops before watering to increase permeability in the rooting zone of plants due to the complete destruction of the vegetation cover.

Known hour tillage of the working body, containing a set of elastic plates of rectangular cross-section, the attachment plates to the frame tillage tools and site wrapline plates to the cutting elements of the working body in which to reduce traction resistance and stability of the progress of the working body depth processing, the mount plates to the cutting elements are shifted back in the direction of travel relative to the site of kreplenie plates to the frame, and the plate is installed with a clearance relative to the longitudinal plane of symmetry of the working body.

V-shaped rack of the working body in the longitudinal vertical plane facilitates the movement of plant and root remains down on the upper slope of the rack and this ensures its purification from plant stems. Performing stand in the form of two parallel plates helps when meeting obstacles to deviate Lancet paw left or right. At the transition of the legs of the loose zone handling in crowded area under the action of the occipital chamfer blades of the working body occurs vyluplyayutsa force (a reaction to the chamfers). This leads to the individual villablino working bodies provodit to the gap between the parallel plates of the soil increases, taking in the middle part of the frame barrel-shaped. At the last hack cracks on perennial plants leads to deformation of the soil together with the roots of plants, causing their death. Upon further movement of the working body in a more friable zone clods of soil, zastryavshie between the plates of the rack, do not allow him zaglubitelja on the source depth. The repeated meeting paws with a solid plot leads to greater villablino working body. In the presence of plant background this will lead to the cutting of roots of plants. Describes the working body is not acceptable for crafts drains to remove excess water. The vertical movement of the feet on the rack, barrel form racks villablino legs and twist to the left and to the right leads to the formation of "torn" wall cracks, resulting in watering them to complete detachment and sedimentation.

Known also working body for selevinia soil in which to reduce traction resistance, curved-concave cutting edge of the knife is made in the form of a parabola with the center of its branches on the middle rack height, with a sharpening angle of the knife at the top and bottom of the parabola decreases the th body is acceptable for cutting slits in the crops of herbs, grain and tilled crops. Curved-concave cutting edge helps to cutting vertical slits without deformation of the soil. There is no violation of the root system of plants. The sharp edge on the bottom of the rack as the working body wears out quickly. Blunt edge of the bottom of the rack causes villablino working body. Uneven depth of the slit results in uneven moistening root layer of soil, which ultimately leads to lower crop yields.

Known working body for selevinia soil that contains vertically mounted knife, on the lateral sides of which there are edges to seal the walls of the slots in which to improve the uniformity of the seal wall cracks on its height by performing in the walls of molehills, ribs made in the form of Polikarpov, the apex of which is posted on the knife blade, while poleconomy located on one surface of the knife, which is offset in height relative to Polikarpov, larger than the distance between adjacent polakowski.

In the described working body of the blade rack is inclined at an obtuse angle to the direction of movement without bringing raw soil. This leads to the fact that the but will increase the volume of the gap and thereby increase the area of wetting of arable and subsoil horizons. Molehills made polakowski who posted longline on lateral sides of the rack. The sharp edge of the base poluchasa leads to the formation of "torn" wall drains. Relaxation of topsoil and soil in the walls of molehills when the supply of irrigation water leads to the detachment of soil particles. Sludge zabivayuca amount of cracks and paludrin. Quality crafts drains and cracks depends on the condition of the cutting edge on the blade rack and from the extent of her sock on the bottom base. The wear of the cutting edge under the influence of abrasive particles and a sock leads to unsustainable course of the working body and, as a consequence, the violation of technological process, crafts drains.

Known also work the body without bringing raw soil containing rack with curved-concave cutting edge and a chisel on the lower section of the rack, which is made in the form of a round rod, set obliquely in the lower section of the rack hole, and lock its position, in which, to increase the service life of the bit, on the surface of the bit is made deeper, the weld hard alloy, spaced throughout the length of its working surface and evenly around the perimeter. The recesses in the rod is placed on forming his RA is on the bottom of the rack provides for raising the ability of hours working body of without bringing raw soil. Curved-edge provides cutting a vertical slit width of 20 mm and depth up to 60 cm vegetable and root residues on the surface of the field only contributes to the creation of sustainable slit by reinforcing its walls. However, dihedral blade is subject to wear, which limits the quality of the process. The obtained vertical slit does not violate the root system of plants. However, to increase the amount of absorbed water is necessary to increase the number of slots on an area of 1 ha (i.e., to reduce the distance between adjacent slits from 1.4 to 0 8.0,9 m), which leads to high energy consumption.

Known saleres containing rack with cutting edges on both sides on a rack made of chamfer and groove with weld material having greater wear resistance than the material of this stand, and the bit at the lower section of the rack, made in the form of a rod and is fixed in an inclined hole of the rack, in which, to improve durability, the rack is made of two side walls, and each groove is made in the form angular recesses on the opposite face from the frame and placed on congruent line with the cutting edge, while the sidewall offset otnositel for the prototype.

In this xelerate removed all the previously described disadvantages. The increase in the volume of irrigation water absorbed when cutting slits data working body can be achieved by increasing the depth of selevinia and reducing the step between the cracks. In the first and second cases, this leads to increased energy consumption. Presents a working body is not acceptable when the crafts drains to remove excess water, and soil aeration.

Declared a work of the authority relates to agriculture and is designed to selevinia soil at the crafts erosion cracks before irrigation of perennial crops, grasses, grasslands, estuaries, with the aim of increasing the permeability of the soil and the exclusion of surface runoff of irrigation water. When replacing a removable annular knife and setting the head part of jenera the same working body conducting the drainage, thereby ensuring the removal of excess water from irrigated areas. For aeration of irrigated areas with poor oxygen content in the soil rack provided in the middle part of the two flat blades.

The back of the Donets 38 grenera provided with rectangular slots 36 for removing or screwing on the output ring 25. The outer surface of the base plate 35 tenera are spherical. The diameter of the sphere Donets 38 grenera made larger than the diameter of the removable cylindrical knife 27. Cylindrical just a hole 21 middle part of the frame 1, the cylindrical surface 30 of the removable cylindrical knife 27 and the cylindrical inner surfaces of the bearings shall onus (see Fig. 5). In the described construction hours 1 working body for selevinia cutting cutting edge 28 of the soil layer remains in its natural undeformed state. At the same time, wall drains condensed in two stages. Blade 29 removable knife 27 is the right phase of the sealing wall and the concave section krivolineynoe part of the side walls 12 and 13 induces relaxation of the soil. After this spherical surface Donets 38 grenera finally form the wall drains.

In Fig. 7-11 shows the working body for selevinia soil in option crafts drains to remove excess water. For this purpose, the support ring 22 of the screw head part of tenera 39, which is made in the form of a truncated portion of a curved cone two planes arranged at an acute angle to the axis of tenera 39. The intersection of the clipping planes 40 and 41 form a cutting edge 42 of the head portion of tenera 39. On the surfaces 40 and 41 are offset relative to each other on opposite planes made a rectangular hole 43 of a width of 5.8 mm and a depth of 1.5 mm, which are weld resistant material. The head part of tenera 39 may be made in the form of a paraboloid of rotation, facing the top of in the direction of movement of the rack rabochego when the crafts drains mount bottom 38 grenera 39. Diametrical hole 44 in the bottom 38 of tenera is intended for screwing on the threaded portion 34 of the output ring 25. In Fig. 11 shows the embodiment of the surface of the base plate 38 grenera 39 as part of a logarithmic spiral, the most appropriate form of relaxation of the material after repeated compression of the soil grenera or punch. The head part of tenera 39 and the bottom 38 are hollow.

In Fig. 12 and 13 provides a working body for selevinia option aeration of the soil. For this purpose, the sidewalls 12 and 13 of the rack 1 is equipped with a left 45 right and 46 feet, made of parts of the side walls 12 and 13. Left paw 45 made in the mirror image of the right paw 46. Left 45 right and 46 feet equipped with blades 47 and 48 with cutting edges 49 and 50. A horizontal shelf legs 45, equally regiment legs 46, moves in a vertical rack 1 on the congruent surface of the threaded ring 35. In the transition zone of the legs 45 and 46 with the surface of the ring 35 of their cutting edges 49 and 50 are placed behind the exit ring 25. In horizontal sections of the left legs 45 and right legs 46 of the blades 47 and 48 is inclined to the axis of tenera 39 (see Fig. 14). This allows for the creation of gaps to maximize the surface for collection and to speed up the process of gathering the excess water on the horizontal to the Oh of the cutting edge 51 of the bit 3.

The working body works as follows.

In the interaction of the rack 1 with soil curved-concave cutting edge 2 of the sidewall 12 provides jamming of the residues in the upper part of the frame 1 between the cutting edge 2 and the soil and cutting (see Fig. 1-6). In the absence of cutting residues are addicted to the depth of the slit is compressed between its walls and pererezaetsya in the middle part of the frame 1, where the sharpening angle of the knife is made smallest. Cut plant residues reinforced wall cracks. When interacting with the ground chisel 3 cuts the layer of soil. The lower edge 7 of the rack 1 with the cutting edge 2 daresay the remaining layers of soil, forming the side walls of the slit and sealing the surface of loose soil received from the bit 3. As a result of compaction of the walls of the slit plant residues and soil decreases them off and sedimentation. With increasing operating time of the bit 3, operating in the most severe conditions of soils, rapidly wears out. Base metal toe rod bit 3 wears out faster, exposing the weld hard alloy 5 plots in prepared recesses 4. The cutting edge 51 of the blade bit 3 assumes a Crescent shape for the variant with increased ucsay samosatene blade 51 bit 3.

During operation, for example, when cutting water-absorbing gaps in perennial grasses, hour (1) cutting edge 2 in the upper part of the cut plant residues on the surface of the field: the roots in the arable horizon, and together with bit 3 in the bottom of the rack 1 mainland soil. As the blade 14 of the left sidewall 12 wears out faster than the filler in the angular recess 16, exposing the cutting edge 2. Upon reaching developments within 180-210 ha in the angular recess 16 filler is used up completely. If additional time 8-12 ha blade 14 on the sidewall 12 is worn equally naked sting filler in the groove 16 of the sidewall 13, forming a new cutting edge along the entire height of the rack 1. When wear of the blades 15 and chipping filler cutting edge 2 is formed of halting on the sidewalls 12 and 13. When the size of the bucket 3-5 mm rack 1 discarded, reaching the time between 500-530 ha.

To provide greater permeability of water in arable and subsoil horizons rack 1 deepened to a depth greater than the arable horizon and thus to the axis of the removable annular knife 27 should be at a depth of 40.45 see if its diameter is not less 160.180 mm. In this case, the cutting edge 28 eat alzieu cutting edge 28 of blade 29 is directed into the hole 37 of the removable knife 27. Performed on the taper hole 37, the support ring 22, the holes 21 of the rack 1, the output ring 25 and the inner bore 35 do not hinder the movement in them the soil cylinder. Soil cylinder is gently placed on the surface drains, which is obtained while cutting the top and bottom of the slit. When cutting soil layer and soil cutting edge 28 of the removable annular knife 27, the outer cylindrical surface 30 (see Fig. 4) seals the wall drains. On the concave parts of the side walls 12 and 13 induces relaxation of the soil. The second phase of the seal wall drains begins bulges 20 on the rear faces of the side walls 12 and 13, and then ends the outer surface of the base plate 35 tenera. Execution removable knife 27 with the inner blade 29, as shown in Fig. 4, it is preferable to use solid and crowded soils. With considerable time working body due to the differential hardness of the material of the blade 29 and wear-resistant material 32 in the annular angular groove 31 is abnormal wear on the inside of the hole 37 a removable annular knife 27. Simultaneously exposing the sting chamfer wear-resistant material 32 in the groove 31, thereby ensuring smooth operation of the knife 27. When pornoho rings 22 and replaced with a new or restored.

When the crafts erosion cracks on crops herbs first or second year of growth, it is preferable to use a removable cylindrical knife 27, shown in Fig. 5. The cutting edge 28, as in the first case, cuts the soil cylinder, which moves freely in the hollow tapered surface of the hole 21 of the rack 1 and is placed in the drain between the upper and lower parts of the slit. The blade 29 intensely plumping wall drains. Deflection wall drain is on the magnitude of the wall of the annular knife 27. After preliminary deformation when passing through the convex portion of the side walls 12 and 13 holes 21 induces relaxation of the soil on the cylindrical surface drains.

Under irrigation by sprinkling with smooth surface and on a slight slope, the excess water from the surface of the field along the walls of the slit is rolled into the drain. With the side surface drains water down to the bottom of the slit. As you fill the bottom of the slit, irrigation water drains and fills the volume of the cavity of the upper part of Selm. As the degree of compaction of the wall cracks and the wall drain is higher than the density of the soil cylinder, irrigation water, the soil swells and fills the cavity drains. Water is ti decreases, this reduces the intensive evaporation of water from the gap. Drena in the middle part of the gap increases the amount of accumulated water and thereby minimizes water erosion of soil. Moisture content in the lower part of the slit and in the middle part of the drain leads to an increase in a wide area of soil monolith in root horizon. Hack narrow slits without disrupting the structure of the topsoil does not damage the roots of fodder crops, which contributes to the rapid re-growth and achieve sustainable harvests of the earth mass of the herbs.

Running hours 1 working body without bringing raw soil with curved-concave walls of the sidewalls 12 and 13 can significantly reduce the surface friction and thereby reduce the total tractive resistance tools. Sharp cutting edges 2 of the rack 1, the annular cutting edge 28 of the removable cylindrical knife 27 and the cutting edge 51 bit 3 provide cutting root and plant residues, soil in the arable horizon and the soil below the plow sole. This ensures the stable performance of the process when the crafts erosion cracks.

For removal izbytochnoi water (see Fig. 7-11) on the rack 1 working body without bringing raw soil with the threaded part 26 operate of tenera 39. Cutting edge 42 grenera 39 set in alignment with the cutting edge 2 of the rack 1. On the output ring 25 special crank inserted into the hole 44, bottom screw 38 grenera with a spherical or curved surfaces. When moving the tools cutting edge 42 of the head portion of tenera 39 cuts the soil. Curved surface grenera 39 and its side faces 40 and 41 of the soil or ground is shifting, forming a round twistie. The walls of the holes are thickened middle part of the head part of tenera 39 and the outer cylindrical surface of the support ring 22. When moving the rack 1 cutting edge 2 of the blade 14 cuts the root part of the plant and the soil layer at the height of the rack 1. The blade 15 moves to the right part of the soil and compacts the wall above and below the drains. With further passage of the rack 1 curved-concave parts of the side walls 12 and 13 induces relaxation (partial recovery of the soil within the size of the gap) soil and narrowing the gap. A curved or spherical surface of the base plate 38 is dopolnenie wall drains. When the crafts drains excess water on a vertical slit and a ditch is directed into the drainage ditch. Silt particles in the waste water as precipitation and cover the filling cracks with soil particles accumulate (sediment) soil impurities on the bottom drains. Double seal wall drains contributes to its stability from obvalivanie walls. These activities ensure the effectiveness of drainage in irrigated areas with high groundwater table.

To improve the fertility and effective use of irrigated lands important to conduct agronomic method aeration of the soil. Technological experiments revealed that the aeration of the soil in the rooting zone feed crop productivity may increase up to 50% compared with the yield on the control. In Fig. 12-14 presents the working body of without bringing raw soil, which, in addition to the removable elements are provided with two horizontal legs 45 and 46. Legs 45 and 46, are placed behind the counter 1, and gradually merge with the surface of the base plate 35 grenera 39 in the sidewall 12 and 13. As in the previously considered cases, the cutting edge 2 of the blades 14 and 15 are cut a vertical slit. The head part of tenera 39 with cutting edge 42 cuts the vertical slit and then forms a cylindrical wall drains. Hardening of the walls of the drains is concem 35 tenera. Cutting edges 49 and 50 of the blades 47 and 48 of the left legs 45 and right legs 46 is cut into horizontal channels for drainage of water and oxygen from atmospheric air in CDF is tcov with cutting edges 49 and 50.

Describes the working body with removable elements are on the fields engaged in agricultural crops, carried out without disturbance of the vegetation cover artwork erosion water-absorbing cracks, drains to drain excess water from the shallow groundwater table and soil aeration, at any stage of organogenesis plants. In tables 1-3 present the experimental data flushing soil geomorphological zones of the Lower Volga region after each irrigation by sprinkling "Frigate", "Volzhanka" and DDA-100MA without selevinia (control), with crafts erosion cracks serial without bringing raw soil MN 2-140 and experimental working bodies of the sample 1991 and 1992 on the frame SN 2-140.
