The invention relates to the field is ranked on the working bodies, designed for pre-treatment of soil under different agricultural crops and disking the soil in gardens, vineyards, berry plantations and nurseries.

There are various designs of disk harrows and combination guns, composed of disk batteries and rippers. As analogues can lead to "Hitch disc harrow".with. USSR N 1410873, "Disk harrow".with. USSR N 1556554, N 1417808, N 1491357, U.S. patent N 4452319 and N 4423789, the Federal Republic of Germany patent N 3509563, the Japan patent N 63-28561, next Combination tillage tool". C. the USSR N 519154, N 184020, N 152978, N 747667, French patent N 2267633 etc.

Known disc harrow with rotating disk rollers under the patent GDR N 204380, class A 01 In 21/08 from 30.11.83, which is used to install Central turntable between frame disc harrows and disk wheels, which are mounted on the auxiliary frame so that it can be rotated to adjust the angle of attack (work), and an auxiliary frame adapted to swing circle and fixed using a locking device with respect to the frame disc harrows.

The disadvantage of the prototype is the lack of spontaneous fluctuations of the rollers, that is what my soil, what is not provided in the design of the device. In addition, the design of the prototype is not provided and also the eliminating factor meglumine rollers. As you know, disc harrows and especially heavy disc harrows different designs to avoid meglumine guns in the process, use either the ballast or additional elements in the design to ensure the stability in the vertical plane, i.e. maintain consistency in the depth of stroke of the gun. In the prototype, as obviously vyhloubene all guns as floating in the working position of the piston rod of the hydraulic cylinder, and the "dead" position, especially on medium and heavy soils.

Thus, the above mentioned disadvantages of the prototype will not give the required quality of the soil and maintain the depth of stroke of the gun.

The proposed device, eliminating the above mentioned disadvantages of the prototype, however, along with providing required if the quality of processing and stability (constancy) of the depth of stroke of the tools through the use of a chisel ploskorezy feet of deep tillers beneath the discs front and rear pairs of sections, mounted to swivel in the horizontal plane of the frame, perform Osia such positive signs, as the purification of the working bodies from sticking soil and clogging of their crop residues in the process of spontaneous oscillations, as well as reducing the overall resistance of the soil working bodies for the alternation of load from one wing to another, from one section to the other, eliminating the possibility of the perception of each of the wing sections drive a maximum load resistance of the soil, due to the structural location of one section of the disk relative to the other in each pair and the asymmetry of the location of the front pair of disks and partitions paws on follow-back pair of partitions drives and clutches.

The aim of the invention is to improve the quality of the soil, the resistance in the longitudinal-vertical plane of movement of the working bodies and the reduction of the resistance of the soil.

This is achieved by the fact that the device contains a frame, supporting wheels, a hydraulic lifting and lowering of the guns, the Central hinges and front and rear sections of disk batteries supplied pokorivshij globaldigitalpay legs, and each pair of partitions of disk battery has a rotary frame, each of which are mounted on the frame by means of a Central hinge and with the possibility of vibrations is dlitelnye legs rigidly attached to the front and rear rotating frames, located directly under the disk batteries and have the appropriate angle solution of 2 , equal to the angle of the solution front front direction and the rear back in the direction of movement of the pair of partitions of disk batteries.

Anterior and middle part of the frame 1 along the longitudinal axis of symmetry respectively set for the front and rear of the Central hinges 6 and 7, the vertical axes are under the frame 1 fixed front and rear of the swing frame 8 and 9 in the horizontal plane of motion. Sitting in the Central hinges 6, 7 horizontal rotary frame 8 (front) and 9 (rear) on the ends made in the form of bent at a right angle to the vertical carrier 10, which in turn planted in bearings copier 11. Copiers oscillations 11 symmetrically arranged on the frame 1 in its anterior and middle parts and made in the form of arcuate slots to put them in the bearings and with the radii of rotation of the front around the vertical axis front center hinge 6 and the rear around the Central axis of the rear hinge 7. The sector arc of each copier oscillations 11 is limited by the angle at 32-30^ocorresponding to the amplitude of the potential fluctuations of front and rear pairs of disk batteries 12, 13 and chisel of subsurface cultivator. - deep tillers 14, 15 having the same angles of solution 2 = 148-150^o. Each pair of disk batteries 12 (front) and 13 (rear) fixed to its rotary frame 8 (front) and 9 (rear) by means of an intermediate rigid vertical is of capabilities correspond to the extreme upper positions of the right-wing sections, and Vice-versa. In front of each pair globaldigitalpay paw 14 fixed to the rotary frame 8 in its Central part with overlapping inner wings and is located directly under the disks batteries at a greater depth. The rear pair each globaldigitalpay paw 15 fixed to the rotary frame 9 at the end of each offset from the longitudinal axis of symmetry and located at a great depth below the rims of the battery. The corner solution of the wings of the paws of deep tillers 14, 15 is equal to the angle of the solution front 12 front in the direction of motion and the back 13 back in the direction of movement of the pair of partitions of disk batteries.

Technologically, the process device includes: a translation of the frame 1 from the transport position into the working position by means of the hydraulic cylinder 3 with a gradual depth in the direction of the unit glubokoryhliteli legs 14, 15 and then disk batteries 12, 13 into the soil; at the same time taking the load resistance of the soil layer, combined working bodies 14, 15 and 12, 13 perform forced oscillations due alternating and continuous change in the angle of attack of the wings paws and disk batteries specified in constructively working phases: phase I (Fig. 2) restrictions Kazi (Fig. 3), the equilibrium uctuations of the bodies 12, 13 and 14, 15, which correspond to the same average values of angles of attack; and III phase (Fig. 4) limitations of the extreme fluctuations of the working bodies 12, 13 and 14, 15 in a clockwise direction.

Globaldigitalpay legs 14, 15 are cut soil layer and rhizomatous weeds, keeping the specified depth, loosen the soil and under the influence of perceived and stored in the wings of the variable resistance produce forced vibrations, which are transmitted through each of the rotary frame 8, 9 through the led 10 and copiers 11 on the General frame 1, and partition the disk batteries, which destroy large lumps, loose cropped soil layer already in the top layer, cut and chop weeds, closing up their soil, and in the process of spontaneous fluctuations of the working surfaces of the disks and paw self-cleaning from the adhering soil (or rather sticking soil) and they seem to be dropped from a hovering weeds and plant residues. However, the forced vibrations of the working bodies 12, 13 and 14, 15 in the soil are accompanied by constant resistance change, i.e. decrease and a slight increase, which will immediately reduce the total nagruzke is implemented by reducing the overall resistance of the soil bed, transmitted through the frame 1 gun on the traction of the tractor.

Technological and constructional features of the device, thus implementing the overall effect is determined on the one hand to improve the quality of the soil, the persistence of the depth of stroke of the working bodies, reduction of the resistance of the soil, and on the other hand, the compactness of the composition of working bodies and short longitudinal database that provides easy control and maneuverability of the unit in operation.
