A device for a rotary soil tilling, drive reservates which is made in the form of a closed gearbox. 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, which is associated with 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 certificate of the USSR No. 442759, AV 49/02, 1974; INF. HP SK STIC, Rostov-don, No. 101-74, 43-75, 101-76).

The closest to the technical nature of the claimed object is a device for rotary soil tilling, containing two rotary scelerata vertically symmetrically along a course 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. Registered in the State register of inventions of the Russian Federation of December 27, 2009, priority, 08 may 2008).

This device has disadvantages:

rotary selaras is a station on the inner side of the ring scelerata that necessitates appropriate space to accommodate the parts of the actuator, increasing the diameter of the annular scelerata and vertical clearance of rotor scelerata;

the drive shaft of the rotary scelerata is located directly above the soil surface, resulting in the process, it is possible clogging of the device by soil and plant residues;

- the probability of clogging of the soil containers to receive the ground, made on the outer lateral surface of the annular scelerata and cleansed from the ground only by the centrifugal force occurring during operation of the device;

- low quality of the machined surfaces of the field, because in the process of soil under the influence of the compression flow of soil and plant residues in the compressed section between the drive shaft and the surface of the soil to form piles of soil and plant residues. These piles spontaneously in the space of cultivated land are exempt from the compressed cross-section in the vertical vibration of the device, fluctuations of relief, or by forced release of the device from mechanical interference with the movement by its short-term growth above the soil;

- additional tractive resistance lane is to the displacement of the device during processing of the soil in connection with the driving elements of the device by soil and plant residues;

- reducing device reliability due to the large diameter of the rotor scelerata that requires the increased energy cost of cutting holes in the ground;

- reducing the reliability of the bearings of the shaft of the rotary actuator scelerata due to linear overload these elements of the device during movement on the treated land due to the effects of the passage of soil and plant residues in the compressed section between the drive shaft and the surface of the soil.

The technical problem whose solution will provide the present invention is to reduce the vertical dimension of the rotor scelerata, during operation of the device will be excluded: clogging by soil and plant remains in a compressed cross-section between the drive shaft and the surface of the soil; the driving extractable soil containers to receive the ground, made on the outer lateral surface of the annular xelerate will be reduced associated with a driving device for more traction resistance to movement of the device in the process of tillage, improved surface quality of the treated field by eliminating compression of the flow of soil and plant residues in the section between the drive shaft and the surface of the soil, increased the reliability of the device in the rotary process selevinia and soil loosening.

The technical result, the floor is chamim in the practical use of the invention, is creating opportunities to make the device movement in the soil at the same time crafts two slots for absorption of water, to perform the milling of the inner layers of the soil, rasplata and mixing them together, keeping the humus layer of plant residues on the soil surface, with high quality, reliability and lower cost of energy.

Before cutting body on the side of the ring scelerata performed capacity for receiving soil, open towards the side and outer cylindrical surfaces of the annular scelerata.

Shaft reservates made with consoles.

Depression of the valve stem actuator is made on the lateral surface of the annular scelerata and oriented to the outer side of the annular scelerata. The lateral plane of the hollow gear is made on the same side of the ring scelerata that capacity for the reception of a ground ring scelerata inside. Relative to the lateral plane of the ring scelerata the side surface of the trench sacale the Oia is most 15-20% of the depth than the lateral plane of the vessel for the reception of the soil.

The front in the direction of rotation of the ring scelerata surface of the hollow gear is made in the same plane with the front in the direction of rotation of the ring scelerata surface vessel for receiving a ground ring scelerata.

The rear bearing surface of the hollow gear ring scelerata made perpendicular to the lateral plane of scelerata inside the tank for receiving a ground ring scelerata. The rear bearing surface of the hollow gear ring scelerata is located in the direction of rotation of the ring scelerata front of the rear in the direction of rotation of the ring scelerata surface vessel for receiving a ground ring scelerata, equipped with a cutting body.

The bottom surface of the basin engagement ring scelerata made perpendicular to the lateral plane of the ring scelerata inside the tank for receiving soil. The hollow gear is made so that the bottom surface of the basin and the top of the outer tooth gear drive gear ring scelerata there is a gap for the ground of the hollow gear. The output ground of the hollow gear is in the process of immersion in her tooth gearing in the transmission of torque from the driving gear to the rotary selenese.

The capacity for the EMA ground ring scelerata performed in the plane of the lateral surface of the annular scelerata extending in a depth direction of the inner cylindrical surface of annular scelerata.

The invention is illustrated the accompanying diagrams: figure 1 shows the proposed device, side view, cross-section B-B; figure 2 shows the proposed device, the front view section a-a left in the direction of movement of the device.

The device is made symmetrically with respect to the movement direction, includes a frame 1, a rotary saleres 2, the subsurface preservation 8, the actuator 22. Rotary saleres 2 contains the disk scelerata 3, the annular saleres 4, reference 5, the centering 6 7 and driven gear of the drive. The subsurface preservation 8 installed on the driven gear 7 rotary Shelestov 2, made with consoles 9, includes a shaft of reservates 10 and soil cutter 11.

Ring saleres 4 equipped performed on its lateral surfaces alternately to the left and to the right along the inner cylindrical surface of a straight hollow gear 12. Reference 5 and 6 and centering led 7 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 13, the complementary internal cavities gearing 12 ring scelerata 4. Ring saleres 4 internal cylindrical bearing surface 14 rests with the toothing on the outer cylindrical bearing surface 15 of the support 5, the centering 6 7 and driven by the gear drive. Each stop on Ernest has a diameter, equal to the corresponding diameter of the engagement.

Ring saleres 4 equipped performed on its outer cylindrical surface alternately to the left and right cutting bodies 16. In the direction of rotation of the ring scelerata 4 before cutting body 16 on the side surface of annular scelerata made open on the side and towards the outer cylindrical surface of annular scelerata 4 capacity for receiving ground 17.

Inside the tank for receiving ground 17 on the side surface of annular scelerata 4 is made hollow gear 18 which is oriented to the outer side of the annular scelerata 4. The front in the direction of rotation of the ring scelerata 4 surface depression gearing 18 lies in the same plane with the front in the direction of rotation of the ring scelerata 4 surface for receiving a ground ring 17 scelerata 4. The hollow gear 18 is made so that its rear bearing surface 19 prevents the contact of the tooth gear 20 and the cutter body 16. Ring saleres 4 through depressions gear 18 gear engages a complementary connected to the teeth of the gear 20, is made alternately to the left (right) in the direction of rotation of the pinion drive 21 on its outer surface.

The drive gear 21 mounted on the drive shaft 22. Bearing 23 of the drive shaft 22 done is on frame 1 of the device.

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 rotary xelerate 2 as follows. From the drive torque delivered to the drive shaft 22 through a gear 21, the engagement elements 18 of the outer drive ring scelerata 4, the engagement elements 12 of the inner drive ring scelerata 4, the elements of the gear 13 driven gear 7 to the shaft of subsurface reservates 10 and soil cutters 11.

Ring saleres 4 in the direction perpendicular to the plane of Fig 1 is fixed in space alternately to the left and right buttons, respectively, and on the support 5, the centering 6 7 and driven gear elements of the gear - hollows gear 12 and the gear teeth 13. In the plane of figure 1 ring saleres 4 is positioned his support surface 14 on the respective abutment surfaces 15 of the support 5, the centering 6 7 and driven gear. This cylindrical surface of the running-gear 5, 6, 7, on which rests the annular saleres 4 of its internal cylindrical bearing surface limiting movement of the ring scelerata 4 in the plane of the disk scelerata 3. The diameter of the cylindrical contact surface of each of the gears 5, 6, 7 and ring sale is ESA 4 is equal to the diameter of the corresponding circle of the gear.

O xelerate 4 torque is transmitted through the outer depressions gearing 18, made on the outer side surfaces of the annular scelerata 4, the gear teeth 20 of the gear 21.

Ring saleres 4 cutting bodies 16 cuts through the slit in the soil.

The stiffness and strength of the ring scelerata 4 are provided with side plates, connecting in the plane of the ring scelerata 4 adjacent in the direction of rotation of the ring scelerata 4 containers to receive the ground 17.

Constructive solution of the annular scelerata 4 provides the presence of a cross-section of developed vertical (cross-section side jumpers capacity to accept a ground ring 17 scelerata 4) and horizontal (cross-section of the internal reference cylindrical surface of annular scelerata 4) planes. The section has a large moment of inertia in the direction of bending of a compression ring scelerata 4 in the plane of figure 1, and when it is bending in the plane of figure 1, little varying along the circumference of the ring scelerata 4.

The soil in the process of cutting with the cutter body 16 comes in located in the direction of rotation of the ring scelerata 4 before cutting the body 16 of the container for receiving ground 17, and then, after lifting capacity for reception, ground 17 above the surface of the soil by rotary ejected from the capacity to accept g is the flying boot 17 on the soil surface by centrifugal force. Rear in the direction of rotation of the ring scelerata 4 bearing surface 19 of the outer hollow gear ring 18 scelerata 4 prevents contact between the cutting edges of the cutting body 16 and the tooth gear 20. The rear bearing surface 19 is made narrow, since it only fixes the position of the ring scelerata 4 relative to the tooth gear 20 gear 21 and does not bear the load of engagement with the transmission of torque.

Rotary saleres 2 throws the soil from the bottom upwards, works from the bottom up.

The subsurface preservation 8 with consoles 9 receives torque symmetrically with the driven gear 7 to the drive shaft of the subsurface of reservates 10 and soil cutters 11, and produces loosening the soil.

High surface quality of the processed field is ensured by the fact that in the process of tillage shaft 20 of the rotor scelerata 2 is located above the surface of the soil at sufficient height to prevent compression of the flow of soil and plant residues in the section between the drive shaft 20 and the surface of the soil. Therefore, residues after treatment of the field device is not collected in heaps, and remain evenly distributed on the surface of the scratch, ensuring its uniform in space mulching, conservation of soil moisture, good conditions of farming p and further processing of the earth. There is no need to forcibly release the device from mechanical interference with his movement on the field due to the formation of piles of soil and plant residues by briefly lifting device above the ground.

In the proposed device is a low likelihood of clogging of the soil containers to receive the ground 17, made on the outer lateral surface of the annular scelerata 4, due to the following circumstances.

After the release of the next vessel for receiving ground 17 of the bottom slit in the soil on a surface centrifugal ejection of soil from the container for receiving ground 17. In the absence of a purge vessel, for receiving ground 17 on this trajectory ring scelerata 4 there is a risk of incomplete cleaning vessel for receiving ground 17.

Then the hollow gear 18, is made on the outer side surface (plane) of the ring scelerata 4, is engaged with the elements, gearing pinion actuator 20, is made complementary to the elements of the gearing of the toothed drive ring scelerata 4. Soil that has not been ejected from the container for receiving ground 17 by centrifugal force, impact by ejected from the hollow gear ring 18 scelerata 4 tooth gear 20 pinion drive 21. Tooth gear 20 is executed in thickness so that prisacariu occupies the entire depth of depression of the gear 18 in the direction perpendicular to the plane of figure 1. The entire element of the soil that is in the tank for the reception of the soil 17, as a result of shock mechanical loads from tooth gear 20 becomes mechanical acceleration in the direction of the axis of the rotor scelerata 2. Energy mechanical inertia, reported considering the volume of material sufficient to cause direct and indirect dynamic mechanical destabilization. Direct mechanical destabilization - direct pressure contact with the tooth gear 20 to the ground. Indirect destabilization due to elastic-plastic deformation of the soil, which is transmitted throughout the mass, not directly in contact with the tooth gear 20. This allows you to knock out tanks for receiving a ground ring 17 scelerata 4 almost the entire inside volume of the soil, even when more than was possible in the known technical solution, the moisture content of the treated soil. The tank 17 is released to receive a new portion of the soil in the process of cutting rotary silerton 2 of the front wall of slaughter is occurring cracks in the soil. Further, the ground, being pushed from the container for receiving a ground ring 18 scelerata 4, falls on the rear in the direction of rotation of the ring scelerata face capacity to accept ground 17, crumbles and is ejected outside the lateral plane of the ring scelerata 4 accelerated the eat, the resulting vector of which is directed perpendicular to this plane.

The release of the vessel for receiving a ground ring 17 scelerata 4 received from her soil is facilitated due to the vibration of the outer surface of annular scelerata 4, which in the process directly applied vibration component of the variable load torque transfer characteristic spur mechanical transmission 20, 18. Vibration weakens the adhesion to the vessel wall for the reception of the ground 17 and the hollow gear ring 18 scelerata 4. This facilitates the centrifugal release of these elements from the soil to the side of the outer cylindrical surface of annular scelerata 4 immediately after the release of the next vessel for receiving a ground ring 17 scelerata 4 from the bottom to the surface. Also facilitated percussion pushing out of the soil, remaining in individual containers to receive the ground 17 and depressions engagement ring 18 scelerata 4, in the direction of the inner cylindrical surface of annular scelerata 4 and further in the direction perpendicular to the lateral plane of the ring scelerata 4. The capacity for the reception of a ground ring 17 scelerata 4 in the plane of its side surface extending in the depth, i.e. in the direction of the inner cylindrical surface of the annular school is erase 4. This allows you to avoid compaction of soil in the tank for the reception of the ground 17 when receiving the ground, and when it is pushing out. The largest soil compaction takes place in the outer part of the vessel for receiving a ground ring 17 scelerata 4 in the narrowest of figure 1 in its cross-section. From this space, the soil is pushed directly by the tooth 20 pinion 21 force, easily drawing then a loose soil, ranging in depth in the tank 17. The tank 17 is cleared and ready to receive a new portion of the soil.

Removing the soil from the bottom slit in the soil with the use of the proposed solution has features.

The upper edge of the rear in the direction of rotation of the ring scelerata 4 support surface 19 of the hollow gear ring 18 scelerata 4 represents a narrow cutting body is made with a blunt cutting angle.

A relatively large cutting angle of the upper edge of the rear support surface 19 causes increased cutting resistance on the part of the front of the face.

However, this feature of the process is important for two reasons.

First, the front cutting considered the upper edge of the rear support surface 19 is narrow, is not more than 20% of the front cutting adjacent main cutting tooth 16.

Secondly, chips, remove the cutter C is BOM back in the direction of rotation of the ring scelerata support surface 19 of the hollow gear 18, performed inside the tank for receiving a ground ring 17 scelerata 4 is formed only in the falling edge of the support surface 19 is already extracted from the bottom of friable material, the removal of which from the wall of the shaft does not involve great effort, the load on the cutting tooth. This chip is already dug up the main cutting bodies 16 material, the removal of which from the surface of the shaft does not involve cutting process. There are only inertial phenomena of secondary dispersal of soil to the peripheral speed of the support surface 19. This causes some weak additional cutting resistance of the soil in the bottom of the slit by rotary scelerata. However, it is clear that using the proposed technical solution of the integral resistance of the rotary xelerate 2 to ground is substantially less than the resistance to cutting of the soil in the bottom of the slit rotary xelerate in the known device.

Large cutting resistance of the soil rotary xelerate 2 in the bottom of the slit in the known technical solution due to the large than in the claimed technical solution, the diameter of the annular scelerata 4. It is known that the cutting resistance of the soil in the pit when the rotary process in the same layer of soil or soil increases in proportion to the diameter of the cutter.

The proposed technical R is the solution eliminates clogging of the device by soil and plant remains in operation, and reduces the associated traction resistance to movement of the device during processing of the soil. Reduced clogging soil containers to receive the ground, made on the outer lateral surface of the annular scelerata. By reducing the traction of resistance to movement of the device increases the reliability of rotary scelerata 2 and the whole device.

Trajectory points annular scelerata 4 during operation of the device is moving the cycloid. With this in mind, on the one hand, the back angle of the sharpening tooth 16 is selected so as to virtually eliminate mechanical parasite inhibitory anti-rotation ring scelerata 4 from the surface of the face at a given speed of linear movement device (feed) and the angular velocity of the rotor. On the other hand, the rear edge angle of the tooth 16 is selected so as to ensure the transmission of torque in engagement with the teeth 20 of the pinion 21 to the front in the direction of rotation of the surface of the hollow gear 18 without any noticeable reduction ratio transmission with the goal of creating stable conditions of engagement in the case of dynamic phenomena of reverse effort engaged.
