Abstract

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, to soil tillage workers. An organ for tiller-free tillage improves the water-air regime of the soil by forming vertical slots across the entire width of the formation being treated. To do this, each vertical knife of the working body is provided with a vertical cable with elastic tubular elements, which is mounted in the rear part of the knife, and there are shares in the lower part. In the plane of the vertical knife, chisel-shaped chaperones are installed. During the work of the working body, the cable clears the gap formed by the vertical knife, sealing its walls. As a result, capillaries are formed in the compacted soil, which for a long time provide moisture to the upper layers of the treated formation. 2 il., 1 s.p. f-ly.

Description

The invention relates to agricultural machinery, in particular to tillage workers, and is an improvement of the invention according to the author. St. No. 1289306.

The aim of the invention is to improve the water-air regime of the cultivated soil by forming vertical gaps across the entire width of the cultivated soil layer.

A vertical cable with tubular elements fixed at the rear of a vertical knife seals the walls of the slot formed by the vertical knife. The diameter of the cable with tubular elements fixed on it is greater than the thickness of the vertical knife. When the plowing unit moves, the cable with elastic elements moves along the slit formed by the vertical knife and, acting on the crushed soil, removes it from the slit, pressing it against the side walls and thereby compacting them. As a result of this side

the cracks are capillary, which ensures the entry of moisture from the lower layers to the upper ones. The rope surface does not stick to the soil, as it is a composite, consisting of elastic elements. When changing the composition of the soil, the speed of movement of the arable farm, the bend radius of the cable changes, the relative position of the tubular elements also changes.

FIG. 1 shows the working body, front view; in fig. 2 is a view A of FIG. one.

The working body consists of a rack 1 with a cutting blade 2 and a plowshare 3, on which vertical knives 4 are located across the width of the grip. On the upper edge of each knife 4 a horizontal knife 5 is fixed. Knives 4 and 5 have cutting edges. On the rear edge of the plowshare 3, cutouts 6 are made between adjacent vertical knives 4. The width of each cutout 6 is equal to the knife length 5. In the lower part of the plowshare 3, the chisel-shaped slits are installed coaxially with the vertical knives 4

Transformers 7. In the upper part of the knife 4 and in the place of the junction of the slot-hole forming 7, a vertical cable 9 is fixed to the lower surface of the plowshare 3 using elastic screws 8. The working surface of the cable is formed by elastic tubular elements 10 made of rubber.

The working body works as follows.

The tool is sunk into the soil to a predetermined depth. As a result of the translational movement of the unit, the cutting edge of the plowshare 3 cuts the soil layer. Soils of slots formed by a chisel-shaped slot along the surface of the slotter are directed to the working surface of plowshare 3. Moving along the surface of plowshare 3, the cut soil layer is cut and divided by vertical blades 4. A part of the divided soil moving between vertical blades 4 , under the influence of horizontal knives 5 is pushed into the notch 6, the other part of the soil continues to move along the surface of the plowshare 3. As a result of displacement of the layers in the vertical plane, the soil is crumbling. The crumbled soil is laid on the compacted bottom of the furrow formed by the plowshare. A part of the soil falls to the bottom of the slots formed by the clippers 7, and the bulk of the soil is exposed to the vertical cable, its elastic plowshares 10. Being fixed in the vertical plane of the knife in the back part, the cable 9 with elements 10 clears the 4 gap formed by the vertical knife , sealed its walls. The cut soil, coming down from the rear edge of the plowshare 3, increases in volume and tends to fill the 4 slit formed by the vertical knife. However, the cable 9 with the elastic elements 10 has a volume larger than the slit formed by the vertical knife 4, therefore the cable not only prevents the gap from filling the soil, but also seals the walls of the gap. On the ground. which is between cable 9 and vertical knife 4, there are two forces directed towards each other: the force arising from the formation movement and the force opposing this movement from the cable 9. Under the action of these forces, the soil is partially compressed and pressed by elastic elements 10 the walls of the slit formed by the vertical knife 4. The surface of the cable, formed by elastic elements 10, prevents the cable from sticking to the soil, since

changes in the composition of the soil or when the speed of the arable aggregate changes, the radius of the cable bend changes. When this occurs, the elastic elements 10 are displaced relative to each other, with the result that the soil sticking to them separates from the elastic movable surface and also presses against the side walls of the slit.

The vertical cable with tubular elastic elements removes the crumbled soil from the slot formed by the vertical knife, presses it against the walls of the slot, thereby compacting them. As a result, capillaries are formed in the compacted soil, which for a long time provide moisture to the upper layers of the treated formation.

The cable surface formed by elastic tubular elements prevents the cable from sticking to the soil, since the radius of the cable bend changes as the soil composition changes or the speed of the plowing unit changes. When this occurs, the displacement of the elastic tubular elements relative to each other,

5, with the result that the soil sticking to them separates from the moving surface of the cable. The chisel-shaped chinkers, installed in the lower part of the plowshare, allow to increase the area of the bottom of the furrow. The bottom of the furrow, formed by the plowshare and chisel-forming chippers, is quite well compacted and is a source of moisture for the upper, crushed soil layer. The larger the bottom area of the furrow, the more moisture it is able to accumulate and give away to plants.
