The invention relates to the agricultural industry, in particular, to devices for subsurface tillage prone to wind and water erosion.

Known rippers soil working bodies which are made in the form of extension springs or equal resistance, the front cylindrical portion which is fixed to the threaded tube [Pat. Of the Russian Federation No. 2113081, 1998] or in the loop []. Of the Russian Federation No. 2112333, 1998].

These rippers passive and strongly deform the ground, creates a large tractive resistance.

A device for subsurface soil treatment containing saleres, core drainer on xelerate and connected with it by means of the hinge axis abrasively arch Ripper elements formed by conical logarithmic spiral [SU # A, 1984] (prototype).

Disadvantages: difficulty of manufacture, high cost of labor in the Assembly - disassembly for repair, loose soil particles, creates a large tractive resistance.

The problem to be solved by the invention is the creation of a quick-design of tenera and intensive high-quality crushing of soil.

This task is solved in that in a soil cultivating the cultivator of the soil on welaratna the knife is mounted a hollow body grenera threaded at the ends, which is sawn in half, the halves are welded to selectname the knife in front�th part screwed on the thread of the expansion head, in rear - nut with sealing ring, mounted inside the housing thrust bearings with shaft associated with the cultivator of the soil, side slit body grenera sealed flat strips in cross-section in the form of an I-beam. The front cylindrical end of the conical spring screw on lovespirals cut the threaded recess of the connecting wiring. The cone angle of the extension spring Ripper is α=15...25°, and the cross section of the spring in the working part is made in the form of a wedge, inclined to the axis of the spring wire at the angle β=10...20°, and the working face of the spring is covered with a wear-resistant material, for example, sorbitol. A variation of the spring Ripper is uniform: the front - cylinder, medium - cone, and in the rear - the paraboloid of revolution of y=xnwhere n=0,5...0,7.

Fig. 1 shows the working body of the soil cultivating of soil Ripper in section; Fig. 2 is a section along a - A of Fig. 1 housing tenera; Fig. 3 - section of the wire of the spring; Fig. 4 - working body with shank spring complex form.

To the rack 1 and fit 2 selectnode knife welded to the top 3 and bottom 4 of the housing halves 5 hollow grenera with threaded ends. The body of tenera made in the form of a hollow cylinder and cut in half lengthwise. Inside grenera on the shaft 6 are mounted thrust bearings 7, the housing grenera front screw secretpolice 8, and rear - nut 9 with a sealing ring 10. The side slit of the housing 5 grenera closed flat strips 11 in the form of an I-beam. The shaft 6 by means of the insert 12 having a left-hand helical groove 13 where is screwed a cylindrical spiral wrapping 14 Ripper, is connected with a conical Ripper 15 of the spring wire. The expansion angle of the conical Ripper α=15...25°. The cross section of the wire 16 in the working part is made wedge, the angle of inclination of the axis of the wedge is β=10...20°, the working face 17 is covered with a wear-resistant material, for example, sorbitol, layer thickness 0,2...0,4 mm. Form Ripper: length of a - cylindrical, the length of the in - conical, at length, in the form of a paraboloid of revolution y=xnwhere the exponent n=0,5...0,7.

The expansion angle α=15...25° is chosen from the condition that each subsequent round cut layer of soil without wrinkling it.

The angle of inclination of the axis of the wedge β=10...20° is chosen from the condition that the wedge was hard and sharpened the blade of the axe.

The design of the spring Ripper at the front of the cylinder for winding onto the insert in the middle - cone for cutting soil in the rear of the paraboloid of revolution of y=xn(n=0,5...0,7) for vspuchivanija (raised) loosened soil.

Soil cultivating Ripper works as follows. On the headland at the beginning of the lure sinks to the soil Ripper, seceretly but� 1 is buried in the soil, drainer 5 forms drains, and under the action of the transverse component of the reaction of the soil on the coils of the spring 15 Ripper they begin to rotate counterclockwise in the bearings 7 grenera 5. When moving the machine tapered portion of the shank of the spring gently, without crushing, cuts strips of soil that are crushed, forming a shank layer, the soil above the working body is lifted. If you increase the resistance (increase the density of the soil), the spring is stretched and loosened the diameter D of the soil decreases, decreasing the resistance of the diameter D increases. Spring wire allows the cultivator to adapt to changing soil conditions. Coating the verge of a wear-resistant material allows samozatachivanie a tool.

When disassembling Ripper Unscrew the nut 9, then 8 head, disconnected top 3 and bottom 4 of the housing halves 5, then turns the shaft 6 of the insert 12.

The use of the soil cultivating of soil Ripper allows you to form a wavy bottom, loose soil turnover, which greatly increases the moisture content. The implementation of the working body and shear elastic type reduces the tractive resistance. The implementation of tenera quick-allows you to quickly replace failed (broken) the working body. Labor productivity increases, Ulu�decreases the quality of soil loosening.
