Description

I

The invention relates to agricultural machinery, in particular to devices that are used for tillage and preparation of breeding areas.

 Tillage devices are known that contain a cultivator mounted on a tractor that is combined with a crop cultivator (I.

The disadvantage of this device is the impossibility of its use for breeding purposes, and more specifically for the preparation of breeding divisions.

Most proposed for this is a tillage device, including a cutter mounted on a self-propelled mine, behind which there is a cylindrical roller made in the form of disks {2 connected by triangular strips.

A disadvantage of the known device is that when tilling the soil in the first stage, it is drained in rows. In addition, it cannot be used to prepare a breeding division.

C (spruce of the invention - reduction of soil drying.

1 This goal is achieved by the fact that the disks are made with a spherical surface and face each other with a concave side, while the triangular sections of the machine are fixed on the disks in a circle whose diameter is less than the diameter of the disks.

FIG. I shows a device for tillage and preparation of a selection plot, side view; in fig. 2 - the same, top view.

The device consists of mounted on

 self-propelled chassis 1 cutter 2, behind which is mounted a cylindrical roller 3, made in the form of interconnected triangular strips 4 of the disc 5. The latter are made with a spherical surface and

.- facing each other with a concave side. The slats 4 are fixed on the disks along a circle whose diameter is smaller than the diameter of the disks 5. The milling cutter 2 and the roller 3 are mounted to the frame 6, which is a welded construction of angular material and is the main connecting link. dinenn device nodes.

The cutter 2 is driven through the cardan shaft 7 from the power take-off shaft of the self-propelled chassis 1. On both sides, the frame b of the device rests on the shoes 8. The device operates as follows. At the site, the line of motion of the device is beaten off and the line of the first pass of the unit perpendicular to it is hung. The unit moves in the shuttle mode, for which at the beginning and end of the section there should be reversal strips 6-8 m wide. Then changing the position of the shoes 8 sets the required depth of tillage by mill 2. By moving the slats 4 along the cylinder generator, set the required width of the rows between the rows (15, 20 , 30, 45 and boom). When the machine moves, the milling cutter 2 loosens and crushes the soil to a predetermined depth with

simultaneous leveling of the surface of the treated strip, which ensures the creation of conditions for the application of a cylindrical roller 3 clearly visible marker lines, even with a small depth (Up to 1.5 cm).

The use of the proposed device allows to significantly reduce the evaporation of moisture in series, which allows

handles, the diameter of which is less than the diameter of the disks.
