The invention relates to the agricultural industry and is designed for cutting water-absorbing slits in the soil and soil loosening.

A device for a rotary soil loosening, cultivating aggregate drive which is made in the form of a closed gearbox. The disadvantage of this drive is the need to promote the reducer through the soil in the technological process of rotational loosening of the inner layer of the soil, due to unproductive expenditure of additional energy, not associated with actually performing loosening (ICP-70; PMS-100; ICP-100M; FS-1,3; SME-2, etc. (certificate of the USSR No. 442759, AV 49/02, 1974; INF. L. SC CSTI, Rostov-don, No. 101-74,43-75, 101-76 - prototype)).

The closest in technical essence to the claimed object is a device for a rotary soil loosening containing two rotary scelerata arranged vertically symmetrically along the direction of movement of the device, mechanically connected with the actuator and positioned below the actuator, the soil cultivating aggregate, which have shafts arranged horizontally and perpendicular to the direction of movement of the Ripper (Patent for invention RU №2376737. Registered in the State register of inventions of the Russian Federation of December 27, 2009, priority from 08 may 2008 - equivalent).

In da�nom device has a disadvantage:

- container for receiving soil, formed on the outer lateral surface of the annular scelerata, cleaned of soil only in one direction by the centrifugal force arising during operation of the device, which determines the probability of scoring capacity of the soil and leads to additional energy for treatment of the soil.

Technical task, which will ensure the proposed invention consists in the improved cleaning from clogging with soil containers to receive the ground formed on the outer lateral surface of the annular scelerata.

The technical result obtained in the practical application of the invention is the creation of opportunities to produce in the motion of a device for milling the inner layers of the soil with high reliability and less energy.

To solve the technical problem is proposed a device for subsurface rotary milling with improved cleaning of the mechanical actuator from the ground. The device comprises a frame, two rotary scelerata arranged vertically symmetrically along the direction of movement of the device and mechanically connected with the common drive and located under the drive of the soil cultivating aggregate, which have shafts that are placed horizontally and perpendicular to the direction of movement of the cultivator. Rotary �alert features a disc of scelerata and ring scelerata. The annular saleres equipped with cutting bodies formed on its side surfaces alternately left and right and pointing in the direction of its outer cylindrical surface. In front of the cutting body on the lateral surface of the annular scelerata made the receptacle for receiving soil. A receptacle for receiving a ground ring scelerata provided with an opening which is oriented perpendicular to the plane of the annular scelerata and performed through the thickness of the annular scelerata.

The invention is illustrated by the attached diagrams wherein: Fig. 1 shows the proposed device, side view, section b-B; Fig. 2 shows the proposed device, front view sectional view a-a right in the direction of movement of the device.

The device is made symmetrically with respect to the direction of movement, comprises a frame 1, a rotary selaras 2, - soil cultivating aggregate with 3 cutters. Rotary selaras 2 contains a disc of scelerata 4, the annular saleres 5, reference 6, centering 7 and driven gear 8 of the actuator. - Soil cultivating aggregate 3 is set in slave gears 8 rotary salariesof 2. The annular saleres 5, performing the role of a gearbox that transmits the torque from the actuator to the soil cultivating aggregate 3, provided with a formed on its side surfaces alternately to the left and right along the inner cylindrical surface�spur ness depressions gear 9. Reference 6 and 7 centering 8 and the driven gear of the drive is arranged alternately with the left and right along the outer cylindrical surface of the outer gear teeth 10, complementary to the internal cavities of the gear ring 9 of scelerata 5. The annular saleres 5 internal cylindrical bearing surface rests engagement with the outer cylindrical bearing surface of the support 6, the centering 7 and driven gear 8 of the actuator. Each support surface of the corresponding kinematic drive element has a diameter equal to the equivalent circle diameter of the gear.

The annular saleres 5 is provided formed on its outer cylindrical surface alternately to the left and right cutting bodies 11. In the direction of rotation of the annular scelerata 5 in front of the cutting body 11 at the side surface of the annular scelerata made open to the side and toward the outer cylindrical surface of the annular scelerata 5 a container for receiving soil 12.

The capacity for the reception of the soil 12 is simultaneously the hollow toothed gear wheel on the outer side of the annular scelerata. The jumper between stacked on the ring xelerate 5 right and left containers to receive the ground 12 at the same time performs the role of the anterior surface of the hollow gear.

The annular saleres 5 depressions gear in the form of a container for receiving ground 12 gearing is connected to the complementary gear teeth 14 are made alternately to the left (right) in the direction of rotation of a leading gear wheel 15 at its outer surface.

The driving gear wheel 15 mounted on the drive shaft, which is mounted on the frame 1 of the device.

The proposed device for rotary-soil loosening operates as follows.

When driving the device on the treated plot the torque is transmitted to rotary scelerata 2 as follows. From the drive torque delivered to the drive shaft, through the gear 15, the gear elements 12 outer drive ring scelerata 4, elements 9 internal gear drive ring scelerata 4, the elements of the gear 10 the spur gear 8 is supplied to the soil cultivating aggregate 3, equipped with a soil cutters.

The annular saleres 5 in the direction perpendicular to the plane of Fig. 1, is fixed in space alternately to the left and right arranged, respectively, on it and also on a support 6, centering 7 8 and driven gear elements of the gear - cavity� gear 9 and the gear teeth 10. In the plane of Fig. 1 ring saleres 5 positioned his inner cylindrical bearing surface and the corresponding bearing surfaces of the support 6, the centering 7 and driven gear 8.

To the ring scelerata 5, torque is transmitted by the gear teeth 14 of the drive pinion 15 through the outer depressions of the gear in the form of containers to receive the ground 12, made on the outer side surfaces of the annular scelerata 5.

Rotary selaras 2 works from the bottom up, throwing out the soil from the face away and up. The annular 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 annular scelerata 5 in front of the cutting body 11 receptacle for receiving soil 12. After lifting containers to receive the ground 12 above the soil surface the soil from it by rotating vented to the soil surface by centrifugal force. Hole 13 provides the output capacity of the soil for the reception of soil 12 on both sides of the plane of the annular scelerata that improves the cleaning vessel for receiving the soil 12. This causes the reduction in the likelihood of clogging of the tank 12 with soil. Enables lower energy consumption for tillage due to the smooth reception of the treated soil in containers to receive the ground ring 12 selera�and 5 without compression and seal.

In the proposed device is a low probability of clogging by 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 to the surface occurs centrifugal ejection of soil from containers to receive the ground 12. In the absence of a forced cleaning vessel for receiving the ground 12 on this part of the trajectory of the annular scelerata 5 is the probability of incomplete cleaning vessel for receiving the soil 12.

Then the capacity for the reception of soil 12 engages with the elements of the gear-pinion actuator 14 made of complementary elements of the gear toothed drive ring scelerata 5. The remaining soil impact by ejected from the container for receiving soil 12 tooth gear 14 pinion actuator 15.

Hole 13 improves the operation of the device at both examined phases of movement of the annular scelerata 5. The first phase centrifugal purification vessel for receiving soil 12 passes more successfully, as in the proposed technical solution the soil has no lateral support on the parts of the annular scelerata 5. Therefore, the soil is easily mechanically destabilizing in the field of centrifugal acceleration, easily split into units and goes out from the container for receiving soil 12. In the second phase force� mechanical treatment of the soil is extruded from the outer part of the container for receiving soil 12 teeth gear 14 pinion gear 15 into the container for receiving soil 12 and into the vast expanse, formed by hole 13. The presence of a zone secondary zone of displacement leads to the fact that the soil has the ability to occupy the soil aggregates in the process of moving the perceived additional rotational and translational force from the rotary elements of scelerata. In this way, the aggregates are destroyed, razukrupnenija, lose adhesion and mechanical connection with the container for receiving a ground connection and seamlessly go from rotary scelerata 5 through the hole 13 on both sides of it.

In both phases the soil under the influence of centrifugal force and being in the process of transverse fluctuations in the hole resulting from the vibration of the machine when working, is experiencing mechanical impact mechanical facets formed by the intersection of the surface of the hole 13 and the plane of the annular scelerata 5. These mechanical effects contribute to torbali and crushing aggregates of soil in the container for receiving soil 12, improving the conditions of purification.

The proposed solution eliminates clogging with soil containers to receive the ground formed on the outer lateral surface of the annular scelerata, due to the fact that they have an opening, which is oriented perpendicular to the plane of the annular scelerata and performed through the thickness of the annular scelerata.

As a result�ATA improving the conditions of the filling containers to receive the ground ring scelerata, reduced resistance to rotation of the rotor in the soil. Accordingly, the reduced tractive resistance movement. Increases the reliability of the rotary scelerata 2 and of the entire device.

The use of a new element in the form of a ring scelerata 5, is provided with a container for receiving ground 12 with a hole 13, which is oriented perpendicular to the plane of the annular scelerata and performed through the thickness of the annular scelerata allows

to produce when driving the device for milling the inner layers of the soil with low tractive resistance reducer scelerata, to disconnect and to mix the layers of the treated soil between them, save the humus layer and crop residues on the soil surface with high quality, reliability and lower cost energy because it eliminates clogging of the soil formed on the outer lateral surface of the annular scelerata containers to receive the ground through the use of cleaning her from the ground on both sides of the rotary scelerata, reduced resistance to rotation of the rotor in the soil and the resistance to movement of the device.
