The invention relates to agricultural machinery, in particular to a device for hilling with soil in between rows of planting potatoes and root vegetables.

Known disk working body of tillage (see RF patent №2093973, IPC AV 23/00, publ. 27.10.1997 ), which contains axle, axle shafts associated with the axle, wheels mounted on the axle shafts with possibility of change of angle of attack and relative position.

The disadvantage of this device is the lack of adjustment of the working body - disks in a vertical plane, which limits the possibility of processing between the rows when the plants maximum growth.

Known Hiller universal (see RF patent №2125353, IPC AV 13/02, publ. 27.01.1999 ), consisting of spherical, symmetrical to the vertical racks concave sides toward each other drives with the possibility of changing the distance between them and adjusting the angle of attack of the discs. The device adopted for the prototype.

The disadvantages of the prototype are limited possibilities of adjustment. Adjustment of the working body of the discs by rotation of the axes in vertical racks. However, when you rotate the axes in the racks there is a change three settings simultaneously and in mutually exclusive directions. So, increasing the values of some parameters,�reamer angle of attack of the disks and the position of disks in a vertical plane, at the same time reduce the value of another parameter - the angle of the disks in the vertical plane, which leads to increased shedding of the soil in the furrow. This limits the possibilities of adjustment, does not allow for good formation of the ridge and, at the same time, increases traction and energy.

The ability to adjust the position of the disks in the vertical plane is limited by the need to ensure acceptable angles of disks in the vertical and horizontal planes.

The invention solves the task of providing quality formation of the ridge and lower energy costs.

The technical result obtained by carrying out the invention, consists in implementing a wide range of adjustment in the processing of row spacing at any stage of plant growth and reducing energy costs.

Said technical result is achieved in that in the Hiller disc consisting of a spherical symmetrically mounted on vertical racks concave sides toward each other drives with the possibility of changing the distance between them and adjusting the angle of attack of the discs, what is new is that the upright is made of two parts in the form of circular pipes that are members of one another can be rotated to control the angle and�Aki disks and axially move the locking parts of the rack in a given position.

The implementation of the uprights of two parts in the form of circular pipes that are members of one another can be rotated to control the angle of attack of the discs, you can:

- to provide a wide range of adjustment of the angle of attack of the disks;

- to form a ridge of soil desired profile.

For processing a light dry soil, the angle of attack is set at 30 degrees. To process heavy crude soil angle of attack is set at 15 degrees.

The possibility of axial movement by locking of the parts stand in a given position allows you to:

- significantly increase the height of the uprights Hiller, and hence the distance from the cross beam of the frame to the soil surface;

- carry out the processing of row spacing and hilling without damage to the plants even when they reach their maximum growth.

Technical solutions with the features distinguishing the claimed solution to the prototype, is not known explicitly from the prior art do not follow. This suggests that the proposed solution is new and inventive.

The invention is illustrated by drawings, where shown Hiller disk.

Hiller disc consists of a cross beam frame 1, two spherical disks 2, two uprights, collected from the upper 3 and lower 4 pipes. Top 3 stand pipe fixed to the cross�Oh beam 1 frame in one of several variants of fixation. The lower portion 4 of the pipe is attached in one of several variants of the provisions in the top tube with the fasteners 5. Spherical wheels attached to the axles 6 through the bearing Assembly 7.

Axis 6 form an angle with the bottom 4 pipe rack, selected according to test results, which provides the disk tilt in the vertical plane.

In the middle of the transverse beams of the frame 1 is formed with a bracket 8 for attachment Hiller to the walking. Fastening is performed by means of the coupling unit (Fig. not shown).

Mating parts - the upper 3 and lower 4 pipe racks have openings 9 through which pass the fastening elements for fixing the parts in the selected position. The transverse beam of the frame 1 has a number of holes 10 for inserting and fixing the upper pipe rack in one of several positions depending on the width of the aisles.

The device operates as follows.

The possibility of rotation of the lower pipe in several positions (at least 2) allows to provide a wide range of adjustment of the angle of attack of the discs 2 and the formation of a ridge of soil desired profile. For processing a light dry soil, the angle of attack is set at 30 degrees. To process heavy crude soil angle of attack is set at 15 degrees. The possibility of axial movement of the lower 4 pipe stand can significantly took�obtain the height of the uprights Hiller, consequently, the distance from the cross frame 1 to the soil surface. It enables the processing of row spacing and hilling without damage to the plants even when they reach their maximum growth. The angle of inclination of the discs 2 in a vertical plane provides for the formation of the ridge and avoids shattering of the soil back into the furrow. This parameter depends on the geometry of the disc of the diameter and curvature of the surface. Once implanted the optimal value of this angle in the future to change it is not necessary - it can be lay in the design as a constant parameter.

Fixation of the pipes 3 and 4, the stand can be made by means of fixing elements 5, passed through the corresponding holes 9 in the mating parts.

The strict symmetry of the setup disk 2 into the working position, which is ensured by precision machining parts, increases the directional stability of the disk Hiller in the works and, therefore, reduce the effort applied by the operator to the controls, and facilitates his work.

Hiller disc consisting of a spherical symmetrically mounted on vertical racks concave sides toward each other drives with the possibility of changing the distance between them and adjusting the angle of attack of the discs, characterized in that the upright �ispolneny two parts in the form of tubes of circular cross section, entering one in another can be rotated to control the angle of attack of the discs and with the possibility of axial movement by locking of the parts stand in predetermined positions.
