Description

The utility model relates to agricultural engineering, in particular to soil cultivation machines, and can be used for inter-row soil cultivation in conditions of water erosion.

A section of the working bodies of a row-crop cultivator-ridge former is known [Author's Certificate RU Patent No. 169780, IPC class A01B 13/00, 2017]. The known section of the working bodies of a row-crop cultivator-ridge former comprises a frame on which a tillage implement, hillers, and a roller pivotally attached to the frame are mounted. A tillage implement is mounted on the frame, made in the form of a reversible loosening paw, rigidly fixed on an S-shaped spring stand with the ability to adjust its height, behind it, with the ability to adjust the height, a combined working element is mounted, on the stand of which a reversible loosening chisel-shaped paw is rigidly fixed, as well as a hilling body with feather moldboards with the ability to adjust the latter according to the height of the stand, behind which a rod profile roller with a chevron arrangement of rods in its cylindrical part is pivotally fixed on the frame.

The disadvantage of this section is the lack of working elements that form pits for the accumulation of moisture in them and prevent its overflow on slopes, as well as the high traction resistance of the rack of the combined working element, reaching a depth greater than the depth of the ripper paw.

The closest analogue to the claimed one, adopted as a prototype, is a section of the working bodies of a row-crop cultivator-subsoiler with a rotary-type hole-digger [Author's Certificate RU patent No. 227093, IPC class A01B 39/14, A01B 13/16, A01B 49/02, 2024], containing a frame on which a reversible loosening paw is mounted, rigidly fixed on an S-shaped spring stand with the possibility of adjusting its height, behind which a reversible deep-loosening chisel-shaped paw with a hilling body with feather moldboards, rigidly fixed on the stand, a rod profiled roller pivotally connected to the frame, a four-blade rotary-type hole-digger.

The disadvantage of the prototype is the low quality of work on soils of different mechanical composition and with different terrain slopes.

The technical result of the utility model is an improvement in the quality of work on soils of different mechanical compositions with different terrain slopes.

When working with the prototype on soils of varying textures and slopes of varying steepness, the reversible chisel-shaped subsoiler is adjusted in depth to ensure stable cultivator movement. At the same time, to form potato field ridges of the required dimensions, the hilling body with the feather moldboards on the shank must be adjusted in height relative to the chisel. However, the rigid attachment of the hilling body to the shank of the chisel-shaped subsoiler on the prototype does not allow for such adjustments, and performance is reduced.

The technical result is achieved by the fact that the hilling body with feather moldboards is attached to the stand of the deep-loosening chisel-shaped paw with the ability to move in height and fix in various positions.

The specified set of essential features ensures that the claimed section of the working bodies of the row-crop cultivator-subsoiler with a rotary-type hole-digger has new properties that are different from the prototype.

Thus, the claimed features of the utility model meet the criterion of “novelty”.

Fig. 1 schematically shows a section of a row-crop cultivator-deep ripper with a rotary type hole digger;

Fig. 2 - section A-A in Fig. 1.

A section of the working bodies of a row-crop cultivator-subsoiler with a rotary-type hole-maker, comprising a frame 1, on which a reversible loosening paw 2 is mounted, rigidly fixed on an S-shaped spring stand 3 with the possibility of adjusting its height, behind which a reversible deep-loosening chisel-shaped paw 4 is installed on the frame in the center of the row spacing with the possibility of adjusting the height, with a hilling body with feather moldboards 5 on a stand 6, a rod-shaped profiled roller 7 pivotally attached to the frame, a four-bladed rotary-type hole-maker 8, wherein the hilling body 5 with feather moldboards is attached to the stand 1 of the deep-loosening chisel-shaped paw with the possibility of moving in height and fixing in various positions.

The working section of the row-crop cultivator-deep ripper with a rotary type hole digger operates as follows.

Before operating the cultivator, the reversible deep-loosening chisel-shaped paw 4 is adjusted in height to a position sufficient to prevent the cultivator from sliding down the slope under specific operating conditions. After which the hilling body 5 is adjusted in height to a position to cut or hill up ridges of a row crop of a given height. The adjustment is carried out as follows. The fixing pins 12, 13 are unscrewed from the eyes 9, 10 (Fig. 2) of the shoe 11. The shoe 11 of the hilling body with the point 14 and moldboards 15, 16 attached to it, put on the rack 6 with its opening, is moved along the rack to the required position until the threaded holes of the eyes 9, 10 are aligned with the corresponding blind holes 17 of the rack 6 and is fixed in this position with the pins 12, 13.

When operating in field conditions, the reversible loosening paw 2 (Fig. 1) on the S-shaped spring stand 3 processes the soil outside the protective zone of cultivated plants to a depth of up to 15 cm. The adjustment of the depth of the reversible deep-loosening chisel-shaped paw 4 is achieved by changing the installation location of the stand 6 in height on the frame 1 and can be up to 40 cm. The hilling body with feather moldboards 5, installed in the required position on the stand 6, performs the formation of a voluminous loose ridge, directing the soil from the inter-row to the center of the ridge with feather moldboards 15, 16. The behind rod profiled roller 7, attached to the frame 1 with a hinged leash 18 and loaded with a compression spring 19, performs the rolling and strengthening of the formed ridge. Rotary pit cultivator 8, whose arm 20 is attached to frame 1 by vertical 21 and horizontal 22 hinges, is driven into the soil by blades 23 under its own weight, moves along the furrow bottom, and forms pits in the furrow bottom. Water accumulating in the pits percolates through the pores formed by the deep-loosening chisel-shaped paw 4 into the lower soil layers, providing protection against water erosion during heavy rainfall on slopes.

Thus, the stated technical result is achieved.
