The invention relates to the agricultural industry and can be used for sealing in the upper soil layer unground crop residues and green manure plants.

Known disk lumiline with round flat disks (T.S. Maltsev System no-till farming / Tsalev. - M: VO "Agropromizdat", 1988. - S. 70).

Known also working body disc harrows spherical shape with V-shaped cutouts and sharpened teeth (as the USSR №934929, CL AV 23/00).

The disadvantage of the working body is the poor quality of work, especially on loose wet soil, and low service life.

The objective of the invention is to improve the quality of work and life extension.

This object is achieved in that the working body of the disk tools, executed the form of a flat round disk with a triangular radial notches spaced evenly on the periphery, teeth alternately bent to the right and to the left and to them rigidly attached removable knives, made of a durable wear-resistant material having a smaller triangular teeth, also bent alternately right and left. The service life is increased due to the replacement of the knives.

Figure 1 shows the working body of the disk tools, side view; figure 2 is a section a - a from figure 1 and figure 3 show the working body without knives.

The working body of the disk tools is a round flat disk 1 with the teeth 2 formed triangular radial cut is made uniformly over the periphery, the teeth 2 are rigidly attached knives with 3 smaller triangular teeth 4 by salep 5 (or bolts). The teeth 2 of the disk 1 and the teeth 4 of the knives 3 are alternately bent to the right and to the left through one. The knives 3 are made of a durable and wear-resistant material and replaced when worn.

The working body of the disk tools works as follows. When driving on the field knives 3 are immersed in the soil for all its length. Because neighboring teeth are bent in different directions, the working party on loose or wet soil is not sinking further. Small teeth of the knives 4 does not allow the stems to slide in the slots of the disk. The knives 3, made of thin, durable material, cut stems, and uncut is pushed into the soil.

Due to tognotti teeth 4 formed in the soil wide slit (slit width equal to the distance between adjacent teeth, bent in different directions). Due to tognotti teeth 2 slits are formed in a staggered manner, not forming a continuous groove. This period of heavy rainfall prevents water erosion and contributes to the accumulation of moisture. Cut the stems of the rotary surface, retaining moisture during prolonged absence of precipitation.

p> The working body of the disk tools, representing a round flat disc with teeth formed triangular radial cut is made uniformly on the periphery, characterized in that the teeth of the disk is rigidly attached knives with smaller triangular teeth, and the teeth of the disk and the teeth of the knives alternately bent to the right and to the left through one.

SUBSTANCE: unit of the present invention includes a flat disc furnished with a mounting hole made at its centre, and teeth. The teeth are made in the form of loosely installed axle-mounted small-sized flat discs arranged on either side symmetrically to the main disc. The small-sized discs vary in diameters, with one half of the discs having diameter twice that of the other half of the discs. The said small-sized discs are positioned equidistant from one another in an alternate arrangement. The distance from the small-sized discs to the main disc is half as much as that from large-sized discs. All discs are journaled at their axes so as to rotate on roller bearings. Both sides of the flat disc feature one additional concave disc. The concave disc features small-sized discs axes rigidly mounted thereon. The concave discs have diameter 10-15% smaller than that of the main disc and are furnished with grooves along their blade edge. The aforesaid grooves are positioned equidistant at each of the discs, with spaces between grooves differing from one disc to another, i.e. distance between grooves made at one of the discs constitutes a 'golden ratio' - 1.6 - with respect to that at the other disc. The flat disc is also furnished with grooves, the distance between them making half the smaller distance between grooves at the concave disc. The flat disc teeth are oppositely inclined in an alternate manner at an acute angle relative to the vertical direction. All discs are rigidly and symmetrically mounted onto a double bushing arranged in the central mounting hole. The concave discs are rigidly fastened by their inner concave surface to the bushing flanges inner surface. The central disc is mounted onto the middle of the same bushing. Blade edges of all the small-sized discs are aligned with that of the concave discs. Additionally, each of the small-sized discs axes features two rigidly mounted discs separated by distance sleeves, with one of said discs being flat and the other concave, both having the same diameter. Note that a concave disc is arranged between flat ones.

EFFECT: enhanced quality of soil processing due to improved plowing efficiency.

SUBSTANCE: work tool consists of disk with assembling aperture in center and circular cutting edge around periphery, and of teeth. Spherical disks of smaller diameter are arranged symmetrically on both sides of a flat disk. All disks are pivotally set on a bushing which is journaled in the central aperture. Teeth are made in form of small disks and consist of one spherical and one flat dick of the same diameter. Tooth disks are arranged in pairs symmetrically around circumference of bigger spherical disks so, that axes of all pairs of smaller disks are rigidly fixed in spherical disks. Disks on axes are pivotally mounted up to a stop. The stop is rigidly fixed on axes of pair disks in such a way, that working edges of smaller disks do not contact surfaces of spherical disks. The smaller disks are arranged alternately: first - flat disk, then spherical, or vice versa and also with alternation of pairs. Diameters of smaller pair disks differ from the neighbour pair by the "golden section" - 1.61 times; these pairs are arranged also alternating with smaller ones. Each successive axial distance of each pair from the plane of cutting edges of spherical disks differs from the preceding one by the golden section" - 1.61 times.

EFFECT: upgraded quality of tillage due to increased efficiency of process of tilling and mixing soil.
