Lack of drive is in need of promotion of the gearbox through the soil in the process of rotational loosening the inner layer of the soil, due to unproductive expenditure of additional energy not related to performing the actual loosening (ICP-70; PMS-100; PMS-100M; FS-1,3; MSP-2 and others).

The closest to the technical nature of the claimed object is a device for rotary soil tilling, containing two rotary scelerata vertically symmetrically in the direction of movement of the device, mechanically connected with a common drive and below the drive soil preservatives that have shafts that are located horizontally and perpendicular to the direction of movement of the Ripper (patent RU No. 2376737, C1 IPC AV 33/02, publ. 27.12.2009 - prototype).

This device has disadvantages:

- cutting annular body scale is ESA executed in the same plane with the rear surface of the vessel for receiving soil, what worsens the conditions of cutting the ground from the side of the vessel interior for receiving soil, because an afflux of soil from the bottom of the tank for receiving the substrate;

- capacity for the reception of the soil, made on the outer lateral surface of the annular scelerata, cleaned of soil in one direction only by the centrifugal force occurring during operation of the device, which determines the probability of clogging capacity of the soil and leads to additional energy to the soil.

Technical task which will ensure the proposed invention, is to provide optimal conditions for cutting soil cutting bodies annular scelerata, improving cleaning from clogging the soil containers to receive the ground, made on the outer lateral surface of the annular scelerata.

The technical result obtained in the practical use of the invention is to create opportunities to make the movement of the milling device internal soil layers with high reliability and lower cost of energy.

The subsurface preservation 3 is installed on the driven gear 8 rotary Shelestov 2. Ring saleres 5 that acts as a reduction gear for transmitting torque from the actuator to the subsurface preservating 3, equipped performed on its lateral surfaces alternately to the left and to the right along the inner cylindrical surface of spur depressions gear 9. Reference 6, the centering 7 and led 8 drive gear is made with arranged alternately to the left and to the right along the outer cylindrical surface of the outer teeth of the gear 10, the complementary internal cavities gearing 9 ring scelerata 5. Ring saleres 5 internal cylindrical bearing surface rests with the toothing on the outer cylindrical support surface of the support 6, the centering 7 and driven gear 8 of the drive. Each bearing surface of the corresponding kinematic element actuator has a diameter equal to the corresponding diameter of the engagement.

alzieu saleres 5 made with cutting bodies 11 on its outer cylindrical surface alternately left and right. In the direction of rotation of the ring scelerata 5 before cutting body 11 on the side surface of annular scelerata made open on the side and towards the outer cylindrical surface of annular scelerata 5 capacity for the reception of the soil 12.

The capacity for the reception of the soil 12 is simultaneously the depression of the valve stem actuator on the outside of the ring scelerata. Jumper between successively arranged on the annular xelerate 5 right and left containers to receive the ground 12 simultaneously performs the role of the anterior surface of the hollow gear.

The capacity for receiving ground 12 ring scelerata 5 provided with a recess 13. The recess 13 is made in the rear surface of the vessel for receiving ground 12 parallel to the plane of the ring scelerata. The side surfaces of the recesses are the internal surface of the vessel for receiving the ground 12 and the inner surface of the cutting body ring scelerata.

Ring saleres 5 has a toothed drive pinion actuator 14. Depression gearing in the form of containers for receiving ground 12 by engagement of complementary connected with the teeth of gear 15, is performed alternately on the outer surface of the left (right) in the direction of rotation, respectively, of annular scelerata 5 and pinion actuator 14. Leading the drive gear installed on the Lou drive, mounted on the frame 1 of the device. Leading the drive gear 14 provided with the teeth of the actuator 15 with the tabs 16.

The proposed device for a rotary soil tilling works as follows.

During movement of the device on the treated plot the torque is transmitted to the rotary xelerate 2. This happens as follows. From the drive torque delivered to the drive shaft, through the gear elements meshing outer drive ring scelerata 4, the engagement elements 9 of the inner drive ring scelerata 4, the elements of the gear 10 driven gear 8 is supplied to the soil preservating 3, provided soil cutters.

Ring saleres 5 in the direction perpendicular to the plane of figure 1, is fixed in space alternately to the left and right buttons, respectively, and on the support 6, the centering 7 and led 8 the gear elements of the gear - offs gear 9 and the gear teeth 10. In the plane of figure 1 ring saleres 5 is positioned his inner cylindrical bearing surface and the corresponding contact surfaces on the support 6, the centering 7 and driven gear 8.

O xelerate 5 torque transmitted by the gear teeth 15 pinion 14 through the outer depressions of the gearing in the form of emkosti the reception of the soil 12, made on the outer side surfaces of the annular scelerata 5.

Rotary saleres 2 works from the bottom up, throwing out the soil from the bottom away and up. Ring saleres 5 cutting bodies 11 cuts a slit in the soil. The soil in the process of cutting with the cutting body 11 enters the button in the direction of rotation of the ring scelerata 5 before cutting body 11 of the container for receiving a ground 12. After lifting capacity for the reception of the soil 12 above the surface of the soil the soil of her rotary emitted by the soil surface by centrifugal force. The capacity for the reception of the soil 12, performed on the outer lateral surface of the annular scelerata, is cleared from the ground force by squeezing the soil by means of the tooth, and inside the tank there is no surface that corresponds to the cavity of the tooth. Improved cleaning capacity for receiving ground is provided by a projection 16, which extracts the additional volume capacity of the soil, stuck between the cutting body 11 ring scelerata 5 and the inner surface of the vessel for the reception of the soil 12.

The projection 16 also provides smooth cutting cutting body 11 during its regular immersion in the face, because the cutting body 11 pre-cleaned. Therefore are not a loss of energy to release the cutter body from the ground, zastryavshe is about and stuck in the tank for the reception of the soil 12 near the cutting body 11. The cutting process of the soil cutting body 11 in the bottom is more efficient because the soil in the proposed technical solution comes with the tool in two directions instead of one, as was the case in the known technical solution. This leads to a reduced likelihood of clogging capacity 12 soil. Reduced energy costs for tillage due to the smooth reception of the treated soil in the container for receiving a ground ring 12 of scelerata 5 without compression and seal.

In the proposed device is a low likelihood of clogging of the soil containers to receive the ground 12 due to the following circumstances.

After the release of the next vessel for receiving ground 12 from the bottom slit in the soil on a surface centrifugal ejection of soil from the container for receiving a ground 12. In the absence of a purge tank for receiving ground 12 on this trajectory ring scelerata 5 there is a risk of incomplete cleaning vessel for receiving a ground 12.

Then the capacity for the reception of the soil 12 is engaged with the engagement elements 15 pinion actuator 14 made of complementary elements of the gearing of the toothed drive ring scelerata 5. The remaining ground shock by ejected from the container for receiving ground 12 tooth gear 14 and pinion when the ode 15.

The projection 16 improves the operation of the device in the second of the two considered phases of movement of the ring scelerata 5 above the surface. The capacity for the reception of a ground ring scelerata 12 provided with a recess 13 on its rear surface is made parallel to the plane of the ring scelerata between the bottom of the tank for receiving soil and a cutting body ring scelerata. Rear in the direction of rotation of the surface of tooth pinion 15 is provided with a projection 16, the width of which is 20-30% of the width of tooth pinion, lateral plane which is executed in the same plane with the side surface of a tooth directed toward the Central plane of the pinion. Due to the selected complementary shaped projection 16 tooth gear 15 pinion 14 and the recess 13 of the container for receiving a ground ring scelerata 12 allows complete cleaning vessel for receiving soil. Also achieved the liberation of the cutting edge of the cutting body 11 and the path of descent of the ground on the next dive in the slaughter.

The proposed solution eliminates clogging by soil containers to receive the ground 12. Also serviceability of the cutting bodies annular scelerata 5.

As a result, improves conditions for the filling of containers to receive the ground ring scelerata, reduced resistance to rotation of the rotor the soil. Accordingly decreases traction resistance movement. Increases the reliability of the rotary scelerata 2 and the whole device.
