Abstract

The utility model relates to agricultural engineering, is intended for use in field crops, in particular, for continuous tillage of fallow fields in the summer. The working body for continuous tillage of fallow fields in the summer period contains a rack, left- and right-sided flat-cutting wings, which are displaced one relative to the other in the longitudinal direction. A chisel-shaped knife is installed with the possibility of replacement in the lower part of the rack. A removable holder is mounted behind the chisel-shaped knife. On the holder, left- and right-sided flat-cutting wings are installed with the possibility of replacement, which are made with the possibility of adjusting the soil crumbling angle β=0÷5°. The proposed working body allows to improve the continuous loosening of the soil to the required depth, including the minimum 4-6 cm with 100% weed cutting, to exclude the removal of wet soil layers to the day surface, and also allows you to get a leveled background of the field after the passage of the unit. 2 ill.

Description

The utility model relates to agricultural engineering, is intended for use in field crops, in particular, for continuous tillage of fallow fields in the summer.

Known working body for processing vapors (RU 2021649 IPC A01B 35/02), containing the mounting part - rack, inclined shield, flat-cutting one-sided paw, inclined blade of the shield, horizontal blade of the paw, transition part, frontal face of the shield. The side surface of the inclined shield is located at an angle of 55° to the horizontal plane, which is less than the angle of internal friction of the soil against the soil (about 57°). The height of the inclined shield is more than 4-6 cm, and the frontal section of the shield is equal to the thickness.

However, the known working body has a drawback, in particular the unsatisfactory quality of loosening the soil.

A tillage tool is known (RU 2023357 IPC A01B 49/02), containing a frame, on the lowerers of which the main bearing element and its working bodies are successively installed and placed perpendicular to the longitudinal axis of symmetry of the tool and its working bodies in the form of one-sided paws located obliquely to the longitudinal vertical plane and a plate. Behind the main carrier element, parallel to it, there is an additional carrier element with similar one-sided paws. The cutting elements of the plate are made in the form of flat knives fixed with an inclination to the longitudinal-vertical plane in the direction opposite to the inclination of the working bodies of the bearing elements. A chain train is installed behind the stove.

The disadvantage of this device is the removal of wet layers of soil on the surface.

Known working body for the care of steam and early spring moisture closure (RU 2401527 IPC A01B 35/26), containing a rack with a vertical shield attached to it, with a front face having lower and upper parts inclined to one another, left- and right-sided flat-cutting wings , which are offset one relative to the other in the longitudinal direction, vertical knives at the ends of the wings. Moreover, the profile of the vertical knives at the ends of the wings forms the upper and lower faces inclined one to the other.

The disadvantages of the known device include insufficiently effective cutting of weeds, loosening and crumbling of the soil, as well as partial removal of wet layers on the day surface of the soil.

By properties and features, this device is closest to the proposed technical solution and is taken as a prototype.

The task of the utility model is to improve the continuous loosening of the soil to the required depth, including the minimum 4-6 cm with 100% weed cutting, and also to exclude the removal of wet soil layers to the day surface.

To solve this problem, a working body is used for continuous tillage of fallow fields in the summer, containing a rack, left- and right-sided flat-cutting wings, which are offset one relative to the other in the longitudinal direction, a chisel-shaped knife is installed in the lower part of the rack with the possibility of replacement, behind the chisel-shaped knife a removable holder is mounted, left- and right-sided flat-cutting wings are installed on the holder with the possibility of replacement, which are made with the possibility of adjusting the soil crumbling angle β=0÷5°.

The proposed utility model is illustrated by the following drawings:

in fig. 1 shows a general view of the working body for continuous tillage of fallow fields in the summer with a set soil crumbling angle of the left- and right-hand flat cutting wings β=5°;

in fig. 2 shows a top view (Fig. 1) of the working body for continuous tillage of fallow fields in the summer.

The working body for continuous tillage of fallow fields in the summer period contains a rack 1, in the lower part of the rack 1 a chisel-shaped knife 2 is installed with the possibility of replacement, a removable holder 3 is mounted behind the chisel-shaped knife 2, on the holder 3 left-handed 4 and right-handed 5 flat-cutting blades are installed with the possibility of replacement wings.

The working body for continuous tillage of fallow fields in the summer works as follows.

When the unit moves at the required depth, including a minimum of 4-6 cm, according to the agrotechnical requirements for shallow and surface tillage, the chisel knife 2, as well as the left-handed 4 and right-handed 5 flat-cutting wings, produce continuous loosening of the soil with 100% cutting weeds and exclude the possibility of removal of wet layers of soil to the day surface. The adjustable soil crumbling angle β=0÷5° contributes to the deepening of the working body to the required depth and is used depending on the agrophysical state of the soil of the cultivated fields. The accepted range of angle β meets the requirements for shallow and surface tillage, an angle less than the specified range does not provide the necessary loosening of the soil, and an angle greater than the specified range contributes to the removal of wet soil layers to the day surface.

The claimed utility model of the working body for the continuous tillage of fallow fields in the summer period makes it possible to improve the continuous loosening of the soil to the required depth, including the minimum 4-6 cm with 100% weed cutting, to exclude the removal of wet soil layers to the day surface, and also allows you to get a leveled background of the field after the passage of the implement.

The utility model can be used on agricultural machines, in particular as a working body on cultivators for continuous tillage of fallow fields in the summer.
