The invention relates to the agricultural industry and can be used for tillage.

Know tillage tool [Tillage tool. Patent RU No. 2186471. Publ. 10.08.2002,] containing a frame installed on it consistently two rows of batteries needle drive, round rod, square or hexagonal and spring baronci. On the frame of the device is additionally installed bevel or worm gear, the input shaft of which is connected to an independent or synchronous PTO shaft to the tractor PTO shaft. On the output shaft of the gearbox installed replaceable sprocket connected by a chain with extra replaceable sprocket on the front intermediate shaft of the device. On the output shaft of the gearbox is equipped with safety clutch. The safety clutch is also installed on the shaft in the upper part of grades rod. The number of replaceable teeth of the sprocket device is selected depending on the type of drive shaft PTO, gear ratio of the gearbox so that different operating conditions the ratio of the translational speed of the unit to the peripheral speed drives battery needle drive was for the front panels in the range of from 0.76 to 1.18, and for rear - within from 0.62 to 1.38 Respect to the translational speed of the unit to the peripheral speed of the rod should be in the range from 0.74 to 0.78.

The disadvantages of the known tools are high energy costs and lack of quality tillage drive batteries needle disks.

The purpose of the invention is the reduction of energy consumption and improve the quality of surface tillage.

This objective is achieved in that the circumferential velocity of rotation of the working bodies of the first row is equal to 1.03...1,1 speed of the tractor, and the circumferential velocity of rotation of the working bodies of the second row - 1,05...1,15 speed of the tractor. The ranks of the working bodies set perpendicular to the direction of movement of the guns with the location of the working bodies in a checkerboard pattern, and working bodies are in the form of needle discs, needles are bent by the involute of a circle. In the tangent planes on the convex side of the needle of the working bodies of the first row is fixed loosening elements that perform in the shape of an isosceles triangle, whose base is parallel to the axis of the needle drive and the top, which is the point of intersection of the equal sides, toward the end of the needle, and the distance from these vertices ripping elements to the ends of the needle is equal to half the depth. On the needles of the second row of the working bodies fix loosening elements made in the form of an isosceles triangle, the apex of which, Blaumana the point of intersection of the equal sides, located at the end of the needle. Loosening the elements of the second row of the working bodies rotate relative to the needle in such a way that they form with the axis of the needle disks acute angle, and ripping these elements alternately rotated about the axis of the needle drive in opposite directions.

In Fig. 1 shows a General view guns for surface soil, Fig. 2 - the same, top view; Fig.3 - working bodies of the first row of Fig. 4 - working bodies of the second row.

Tool for surface soil contains a frame 1, a mounting device 2, the drive rotary operating parts 3 and 4 of the first and second row, respectively. On the frame 1 is mounted a bevel gear 5, the input shaft 6 which is connected with the synchronous shaft PTO drive shaft 7. On the output shafts 8 conical gear 5 replaceable sprocket 9 and 10, connected by chains 11 and 12 with replaceable sprocket 13 and 14 respectively on the front and rear rotary shafts of the working bodies. Gear ratio of bevel gear 5, replaceable sprocket 9, 10, 13 and 14 are selected so that the peripheral speed of rotation of the working bodies of the first row was equal to 1.03...1,1 speed of the tractor, and the circumferential speed of rotation of the working bodies of the second row - 1,05...1,15 speed of the tractor. The ranks of rotation what's working bodies 3 and 4 are installed perpendicular to the direction of movement of the guns with the location of the working bodies 3 and 4 in a checkerboard pattern. Working bodies 3 and 4 are made in the form of needle discs, needles are bent by the involute of a circle.

In the tangent planes on the convex side of the needle 15 working bodies 3 of the first series of Ripper fixed elements 16 in the shape of an isosceles triangle. The base of these triangles are parallel to the axis of the needle drive. The vertices of the triangles, which is the point of intersection of the equal sides, toward the end of the needle 15, and the distance from these vertices ripping elements to the ends of the needles 15 is equal to half the depth of processing.

On the needles 17 of the second number of working bodies 4 Ripper fixed elements 18, also made in the shape of an isosceles triangle, the apex of which being the point of intersection of the equal sides, is located at the end of the needle 17. Ripping elements 18 of the second number of working bodies rotated relative to the needle 17 so that they form with the axis of the needle disks acute angle β, and the loosening elements 18 are alternately rotated about the axis of the needle drive in opposite directions.

Tool for surface tillage works as follows.

Before driving the unit in the transport position, the tools include the PTO of the tractor, from which the torque is transmitted through the propeller is Ala 7, the input shaft 6, the bevel gear 5 on the output shaft 8, through replaceable sprocket 9 and 10, the chain 11 and 12, replaceable sprocket 13 and 14 on the front and rear shafts and rotary attachments 3 and 4 of the first and second series, made in the form of needle-shaped disks with mounted loosening elements 16 and 18, respectively. Further, in the beginning of the movement with the help of the mounted device 2, the instrument is switched to the operating position. In this case, rotating the working bodies 3 of the first row, perform strip tillage her front loosening margin and working bodies 4 of the second row loosened soil deformation strain in the adjacent untreated strips, working at her needle drive and rasplata loosening elements 18, alternately rotated in opposite directions from the axis of the needle drive, in the direction already loosened strips.

Reduce energy costs and improve the quality of surface tillage is achieved by the fact that the circumferential speed of rotation of the working bodies of the first row is equal to 1.03...1,1 speed of the tractor, and the circumferential speed of rotation of the working bodies of the second row - 1,05...1,15 speed of the tractor. It provides soil loosening the tension of separation and the creation of reactions aimed in the direction of motion of the aggregate first range of rotation of the working bodies, as well as loosening the soil to the pubic by cutting with a margin without transportation and the creation of reactions, aimed in the direction of motion of the aggregate second-row rotary working bodies. In addition, it ensures self-cleaning of the working bodies and eliminates scrivanie soil working elements.

Improve the quality of surface tillage and reduced energy costs is achieved on account of the location of the ranks of the working bodies perpendicular to the direction of movement of the gun, placing the working bodies in a checkerboard pattern. This also contributes to the implementation of the working bodies in the form of needle discs, needles are bent by the involute of a circle, and fixed in the tangent planes on the convex side of the needle of the working bodies of the first row ripping elements in the form of an isosceles triangle, whose base is parallel to the axis of the needle drive and the top, which is the point of intersection of the equal sides, toward the end of the needle, and the distance from these vertices ripping elements to the ends of the needle is equal to half the depth. This allows you to perform a strip tillage front loosening half the depth of the tilling with a significant reduction of energy consumption for transverse movement of the reservoir when a predetermined limiting the depth of processing.

Performing loosening of the elements of the second row of the working bodies in the form of an isosceles triangle, the vertex of which is s, which is the point of intersection of the equal sides, is located at the end of the needle, twist the ripping elements relative to the needle in such a way that they form with the axis of the needle disks acute angle, and the alternate rotation ripping elements with respect to the axis of the needle drive in opposite directions allows you to loosen the soil with a deformation strain in the adjacent, not processed the first next working bodies, the strips of soil alternate effect aimed in opposite directions ripping elements, which also increases the quality of surface soil and reduces energy costs.
