The invention relates to agricultural machinery, in particular to machines for tillage.

Known disk plough body containing a rack, on which is mounted a spherical disk and secured additional working body, with the possibility of changing its position relative to the plough body (RU, patent for invention №2152701, CL AV 15/16, 23/06, 2000). This solution has a number of disadvantages. In particular, when working on proscaronline felling plow hammered wood-cut residuals that fall between the spokes and additional working body. When this occurs the necessity of stopping the machine and cleaning of the working body, which reduces the efficiency. In addition, a layout solution disk plough body makes it unnecessarily expensive and cumbersome. The transfer of such solutions on other disk tillage machinery (harrows and stubble) may increase the cost and increase the metal design tools.

Closest to the claimed technical solution is adapting to the disk lusignolo for turnover and crumbling of the reservoir, taken as a prototype, including a rack, a cylindrical blade and mechanism for regulating the position of the blade relative to the disk lumilikha (SU inventor's certificate No. 1074425, CL is M 5/00, 7/00, 1984). Practice shows that the presence of soil solids (rocks and woody debris) in view of the specific conditions of guns leads to deformation of extreme disk lumilikha. Resulting in an unstable gap between the disk and the blade, through which passes a portion of the soil, thereby reducing turnover and reducing the quality of its installation. In addition, it is not excluded the possibility of residues in the gap, which can lead to the braking disks lumilikha and increase the intensity of the process of soil.

The purpose of the invention is the improvement of the quality of soil under different technological regimes disk tillage implements and the lower energy process tillage.

To achieve this goal it is necessary to minimize the gap between the disk and the blade and to ensure its stability angle of rotation, eliminating the possibility of passing through soil and plant residues. For this purpose the blade in the invention is equipped with a cylindrical hinge, an elastic element and a roller with eccentric axis of rotation. Such fastening of the blade allows him to copy the working surface strain of working bodies, providing a guaranteed minimum gap. Elastic element to sposobstvuyushaya the position of the blade and ensures a constant contact of the roller with the working surface of the disk.

The invention is illustrated by drawings, where figure 1 shows a device to a disk tillage tool, side view; figure 2 is the same, rear view; figure 3 is a section a-a in figure 2.

Adaptation to disk tillage implement includes a blade 1 (figure 1). The blade 1 is mounted on the concave side of the disk 2, with the possibility of changing its height and inclination of the working surface of the disk 2, by means of the rack 3, the cylindrical hinge 4, the lugs 5 and the elastic element 6 (figure 2). A cylindrical hinge 4 consists of a sleeve 7 and pin 8 is fixed by a cotter pin 9. Hour 3 is installed in the guide 10 and secured by the screw 11. On the blade 1 in the lower part of its back surface mounted roller 12 in contact with the working surface of the disk 2, the eccentric axis of rotation 13, the amount of eccentricity which is equal to e (figure 3). The axis of rotation 13 of the roller 12 mounted in the lugs 14 and secured by means of nuts 15, precluding inadvertent rotation in the holes in the lugs 14.

Adaptation to disk tillage tool works as follows.

Before you begin the device is set to the specified machining regime, adjusting the position of the blade 1 so that they are optimally interact with the soil layer. To do this, loosen the screw 11 and move the stand is 3 in the guide 10, installing the blade 1 in the desired height position. Then produce a tightening screw 11. Next, loosen the nut 15 and the rotation of the eccentric to the axis of rotation 13 (adjustment range 2E, figure 3), installed in the holes in the lugs 14, achieve education guaranteed minimum gap between the disc 2 and the oval 1. Then make the nuts 15.

When driving disk tillage tools disk 2, interacting with soil, rotates, it cuts off the soil reservoir and delivers it to the blade 1. Mount blade 1 allows him to copy the working surface of the disk 2, while providing a minimum gap around the entire circumference of the contact disk and blade, and except for the passage through it of the soil and plant residues. As a result, the soil layer qualitatively crumbles, turns around and laid on the field surface smoothly with minimum energy consumption.

The use of the proposed device allows to improve the quality of soil under different technological regimes disk tillage tools and to reduce the energy intensity of the process of soil.

SUBSTANCE: cultivation method of seed and planting onion to bulb onion in irrigated farming includes unstriped planting and treatment. After harvesting the preceding crop in autumn, wide ridges 0.14-0.22 m height are created in the topsoil. Grooves are created between the wide ridges for creation of technological track with the base of 1.4-1.6 m. In early spring after warming up soil in the ridge to the temperature of +2...+5°C the seedbed is created along the ridge in its basis. The seedbed has the form of cylindrical surface with bulge in the direction of the ridge's top. Planting of the seed onion and planting onion is performed in the top of the centre of equilateral (regular) hexagon. Long radius of regular hexagon is equal to average diameter of the seedling of chosen hybrid of onion breed. After planting the seedlings are covered with the layer of granulated soil from the ridge. The topsoil gets compacted creating equidistant surface in the seedbed. The flexible drip line is put over compacted top of the ridge.
