The method includes the cutting of the layer horizontally in the transverse section in the form of an ellipse, the major axis of which is inclined from the vertical to the surface of the slope in the direction of his foot, or vertices. Crushing layer is produced by bending in perpendicular planes, and its turnover and laying in their own furrow. At the bottom of the furrow through equal distances form the raw parallel to the contour lines of the slope crests, peaks of which are at the level of plough pans, and spiral grooves. Trimming the seam perform below the plow sole, i.e., to a depth of A1,3h, where h is the distance from the surface of the soil to plough pans, and the thickness and width of the cutting layer are in the ratio 5: 7-8. Working bodies for execution of the method is executed in the form of a spherical ring having a reverse curvature in the zone of smaller diameter, which is equipped with additional working body, made in the form of a hollow body of rotation with the inner curved generatrices and outer rectilinear form.

The invention relates to the agricultural industry, in particular to methods of tillage on slopes and devices for its implementation.

Known methods of tillage on slopes, for example: A. with. USSR N 1521322 MKI A 01 B 79/00; H 01 13/16, 1989, N 1454275 MKI A 01 B 79/00, 1989, N 1353336 MKI A 01 B 79/00, 13/16, 1987

To implement these methods are used tillage tools with passive working bodies (or subsurface cultivator. lemasney ploughs), which form at the bottom of the furrow compaction plow sole (Trufanov centuries Deep chizelevanie soil /Vsesojuzn. Acad. C. agricultural Sciences.- M: Agropromizdat, 1989, s 9).

"Plow sole" is called compaction of the soil in the layer located below the passage of the blades is the result of compaction of the soil layer contains the minimum number of pores.

Formed by a compacted layer further prevents the absorption of soil and normal growth of the root system of cultivated plants, leads to erosion processes.

There is a method of conservation tillage.with. N 1297741 MKI A 01 B 79/00, 1987), including the alignment surface and crafts for surface tillage wavy furrows to form between their crests closed holes. When this surface soil layer are cut in waves with the height of the wave profile 2-4 cm

The method requires a lot of energy, because the device for implementing the method applied working bodies with the active drive.

The method is ineffective because the increase of water absorption will be negligible due to the shallow surface tillage of the soil round cultivator-loosening plates.

There is a method of soil treatment.with. N 1250183 MKI A 01 B 79/00, 1986 ), including surface loosening the soil to a depth of seeding with ribs seed bed with amplitude of 1.0-1.5 cm

This method is also inefficient because of the shallow depth of processing.

When using the discussed methods of tillage to Quilichini water absorption and reduction of erosion processes. Also, do not create favorable conditions for the development of the root system of plants.

Closest to the proposed to the technical essence and the achieved result is a method of processing soil and.with. N 1429961 MKI A 01 B 79/00. It includes cutting curly layers of soil with variable cross-section in an inclined position on the arc with the subsequent separation in the horizontal plane and the back of each soil layer with the location of stubble up and back at an angle to the rear surface of each of the previous layer.

The lack of plough pans, improves vertical filtering of precipitation.

However, this method is applicable only in wet soil, and involves the turnover of the layers in the adjacent furrow, i.e. the method does not provide a smooth plowing, including on the slopes.

The purpose of the invention is the increase of water absorption slopes, reduced erosion, reduced energy consumption and the creation of favorable conditions for development of the root system of plants.

This goal is achieved by the fact that in the present method smooth ploughing slopes, including the cutting of the layer contours, its crushing by bending in the plane perpendicular the first axis is tilted from the vertical to the surface of the slope in the direction of his foot, at the bottom of the furrow through equal distances form the raw parallel to the contour lines of the slope crests, peaks of which are at the level of plough pans, and spiral grooves. While trimming the seam perform below the plow sole, i.e., at a depth of 1.3 h, where h is the distance from the surface of the soil to plough pans, and the thickness and width of the cutting layer are in the ratio 5: 7... 8, and the layer rotation is performed with the rotation in the direction up or down the slope, and placed in its own furrow.

An example of the method.

Practical implementation of this method smooth ploughing slopes preferably in the autumn as autumn plowing.

In Fig. 1 shows the soil to be processed by the proposed method shows a vertical cross-section of the layers, cutting the working bodies (rear view: a - when plowing with a turnover of right b - when plowing with a turnover to the left).

In Fig. 2 given the precarious situation of layers before falling into the furrow with a complete revolution down the slope.

In Fig. 3 shows the position of the reservoir after the fall in the furrow.

In Fig. 4 depicts the device used to implement pedogenetice shows the order of placement on the frame of the plow device driver plowing (top view, I position) and left-hand plowing (position II).

Way smooth ploughing slope of the land is as follows. Plowing start from the top or the bottom of the slope. The turnover of the layers can be performed in the directions up and down the slope. Arable unit moves along the contour Shuttle method. First cut the soil layers I, II, III (Fig. 1) in cross section as part of the ellipse USED at a distance "b" from each other, where "b" - width single case.

To ensure turnover of the reservoir in its own furrow with minimum energy consumption, provide the inclination of the major axis of the ellipse from the vertical MN to the surface of the slope, depending on the direction of circulation of the layers, in the direction of his foot or peak at a certain angle . At the bottom of the furrow through equal distances in" raw form ridges parallel to the contour lines of the slope, the peaks of which are at the level of plough pans, and spiral grooves. Cutting layers produced without the formation of plough pans to a depth of 1.3 h, where h is the distance from the surface of the soil to plough pans, and the thickness and width of the cutting layer are in the ratio 5:7... 8.

Obrazovanost with spiral grooves promote more intensive moisture retention in the soil, to prevent dripping it down the hill and elimination of water erosion.

When the above-mentioned ratios of the dimensions of the thickness and the width of the cutting layer produces the desired height raw ridges on the bottom of the furrow and provides a steady turnover of layers.

After that, the soil layer is deformed by bending in the perpendicular planes (in the longitudinal and transverse directions). Under the influence of tensile stresses in the reservoir cracks, which destroy the soil structural aggregates with a minimum expenditure of energy.

Then produce a turnover of layers. It is carried out with a small lift and rotate in the direction for example, down the slope relative to the ribs C (Fig. 1A) and placed in its own furrow without lateral offset.

When the layer rotation in the direction up the slope it also raise (but to a slightly lower height), produce rotation relative to the ribs (Fig. 1B) and placed in its own furrow.

Smooth plowing slopes on the proposed method performed by the device - combined working body of the rotary type (Fig. 4). Working body consists of a spherical ring 1, keyserling movement (Fig. 6) and the vertical (Fig. 4).

Spherical ring provided with an additional working body 3 made in the form of a hollow body of rotation with the inner and outer curved rectilinear form. Additional working body 3 large base rigidly fixed to the spherical ring. Their internal working surfaces gradually merge into each other. The outer surface includes a liner and attached rotatably to the rack 5 through the base 6 and the cover 7 of the sliding bearing. On the inner surface of the ring 1 and additional working body 3 attached along the forming pins 8, equipped with cutting edge.

When the design of the proposed device, it is important to keep a certain ratio of the diameters of the spherical disk and additional working body depending on its destination on the depth of processing.

Device for smooth ploughing slopes is as follows.

Before you begin the movable beam 1 with a fixed working bodies, is set, for example, in right-hand position 1 (Fig. 6). In this case, the rotary working bodies 2 are in the right dir is i.i.d. angles to the direction of movement and to the vertical, delves into the soil and cuts the seam along the curve of the ellipse (Fig. 1A,b), which under the action of applied forces begins to rise along the working surface of the spherical ring 1 (Fig.4). Rising on its surface, the layer is subjected to bending deformation in the perpendicular planes.

At the transition from the spherical surface of the ring 1 on the additional surface of the working body 3 layer is exposed to a strong bend (kink) in the longitudinal direction, but in the opposite direction. Upon further movement of the soil layer passes inside additional body 4, interacting with its working surface. When the pins with the cutting edges 8 during movement of the reservoir runs into him at some depth and cause it to rise to a certain height, rotating together with the working body. Here also is the bending of the reservoir in two perpendicular planes.

As the movement inside additional working body 3, the intensity of the deformation of the reservoir increases, since increasing the curvature of the working surface. The maximum deformation layer is exposed in the area of the smallest of its internal diameter. Bending near the ruins of the reservoir with what's in the reservoir cracks and it breaks the structural units.

After reaching a certain height, the layer of soil under its own weight comes off additional working surface of the working body 3 and drops down with a complete revolution in their own furrow.

By increasing the inner diameter of the additional authority in the area of the output layer provides additional toughness (due to the use of inertia forces of the reservoir) and more aligned with the surface of arable land.

Due to the presence of teeth (conventionally not shown) on the cutting edge of the spherical ring on the bottom of the furrow formed spiral grooves.

The operation of the device will occur without shooting and qualitatively in the case when the depth of tillage, the diameter of the spherical ring and the smallest inner diameter additional working body are in the ratio 1:3,9...4,5:1,3...1,5.

Depending on the way of plowing the turnover of the reservoir may be arranged in directions both up and down the slope. However, from the point of view of energy, the layer rotation in the direction down the slope is preferable.

At the end of the rut plow lift to the transport position and the movable beam 1 (Fig. 6) with a combined working bodies 2 is transferred to vertical. The turnover of the reservoir is also down or up the slope in their own furrow.

The proposed device for smooth ploughing soil works perfectly and in horizontal sections. And when it is used for smooth ploughing slopes are used all his benefits, and get the greatest effect.

The proposed method of ploughing increases water absorption and reduction processes of water erosion by creating loose with the helical grooves of the bottom of the furrow, and the generation of raw ridges parallel to the contour lines of the slope, below the layer plough pans. Creates favorable conditions for the development of the root system of plants.
