Between the legs and smoothing of the rotor reduces energy costs for his drive and eliminates the appearance in the system MTA circulating power. The separation between the teeth of the fragments of the layer is less energy intensive than cutting knives.

However, this scarifier has increased the cost of power to push the loosened layer through the back row of the stands legs. On the agricultural background, weedy plant residues, work replicale-rotary plows hindered by their driving. When mounting such a plow with the tractor drive concept increase the power losses on the slip. In addition, the process of loosening the rotor is not enough rational, as when a vertical dive into the top layer of the soil of his teeth have high resistance, the reactions is which does not aim at pushing the plow, and up on his vyhloubene, and on this part of the tooth movement of soil fragments almost do not separate.

Closest to destination and the device is a rotary scarifier (plow) with forcibly rotating Zubov rotor and placed in front of them globaldigitalpay paws / Zhuk A. F., Khalilov, M. B. Finding types of working bodies of the rotary plow. Scientific technical Bulletin VIM, No. 79, 1990. - S. 3...6. - prototype/.

The plow does not waste power by pushing the reservoir through the racks, however, when dealing with agricultural background, weedy plant residues, also driven, and the plot vertical dives in the topsoil of his teeth, not separating soil fragments that have a high resistance, a reaction which does not aim at boost the plough, up to his vyhloubene. When mounting the plow to the tractor drive concept of the substantial loss of power to the slipping.

An object of the invention is to reduce the intensity of loosening the soil with a rotary scarifier and the cost of power for the drive of the rotor, as well as sustainable execution of processing of agricultural background, weedy plant remains.

The goal of the project is achieved in that the rotary scarifier, containing a frame with a mounting device, PEFC is therefore mounted gearless Ripper working bodies, forcibly rotating the rotor with teeth on a horizontal shaft and mechanism drive according to the invention Ripper working bodies are made in the form of spherical disks installed with angle of attack before the teeth of the rotor, the diameter of which at least one and a half times the diameter of the disks, and the disks are adjustable in elevation relative to the rotor which is convex to the longitudinal axis of the chisel and located above the lower line of the body of the rotor by an amount not less than half of the radius of the disk, in addition, the device for coupling disks with a frame made with elastic elements, the teeth of the rotor is equipped with a removable work devices, and the rear rotor is placed rink with adjustable limit the height of his ascent. The invention is illustrated by drawings.

In Fig.1 shows a rotary scarifier, side view, Fig.2 - the same, top view.

Rotary scarifier includes a frame 1 with the connecting device 2, the guide posts 3 with a screw mechanism 4 for vertical movement of the beam 5 with the attached disk working bodies 6 and mechanisms 7 adjust their angle of attack, sections (left and right) of the rotor 8 with the shaft 9, the teeth 10 and the interchangeable test device (bits) 11 on them, the frame 12, pivotally coupled with the frame 1, ka is OK 13, black Guillemot 14 and lanyards 15 to adjust the depth (height of the rink).

Rotary scarifier contains the drive mechanisms of the rotor 8 from the shaft of the power takeoff (PTO) of the tractor: cardan transmission 16, the cylindrical gear 17, the transmission 18 from the cylindrical 17 to the Central gear 19 mounted on the platform 20. Driven shaft of the reduction gear 17 is connected to the shaft sections of the rotor 8 by means of gear couplings, clamps (coupling) is placed in the shaft 9 of the rotor 8.

Disk working body 6 contains spherical disk 21 mounted on a shaft mounted in a bearing unit, the casing of which is fixed on a spring (or spring) rack pivotally coupled with a swivel bracket mounted on the beam 5 and connected to the traction mechanism 7 adjustment of the angle of attack of a number of disks. Disk working bodies 6 and the teeth 9 on the shaft 8, are installed with an interval of width 35 cm Shaft 9 of the smoothing section of the rotor 8 at one end includes a coupling for connection with the shaft gear 19 and at the other end of the axle, mounted in bearings fixed to the frame 1. On the shaft with safety finger (bolts), shear accidental loads, fixed clip 22 with flanges that have the teeth 10. The diameter D of the rotor 8, at least one and a half times the diameter d of the disk 21, which hosted the conference use the lower body line of rotation of the rotor by an amount over half their radius.

Rink 13 is made in the form of a drum with teeth. Axle drum mounted in bearings fixed to the frame 12.

The beam 5 is fixed adjustable mounting reflectors 23, preventing the dropping of the soil at the disk beyond the treated rut.

Before you begin the scarifier establish the desired depth of treatment Zubov rotor 8, adjusting the lifting height of the rink 13 by means of turnbuckles 15. Then screw mechanisms 4 vertically move the beam 5 with the disk working bodies 6 and set the desired (8...12 cm) deep tillage discs 21. Then include the PTO of the tractor. Using the hitch of the tractor, put the chisel on the ground and start moving along the rut.

During the operation of the chisel disks 21 before the teeth 9 of the rotor cut plant residues and rake strip depth and width of about 10 cm, and the soil of the new furrows throw in a side of the longitudinal axis of the chisel.

The teeth 10 of the rotating shaft 8 penetrates into the reservoir in the furrows formed by the spherical disks 21. This reduced the depth of movement of the teeth 10 in a monolithic soil processed layer, because of furrows excluded plot the vertical dip of the toe of the tooth 10 into the reservoir, where the fragments of the square is one hundred are not separated from the monolith. In the absence of furrows only vertical (vyluplyayutsa) reaction would affect the working device 11 of the tooth 10. When immersed in the furrow of the working device 11 of the tooth 10 is moving in the soil not only downwards, but also backward. When a tooth is knocked back soil fragments (chips) and experiences a reaction resistance, aimed forward at the push of a scarifier. Its tractive resistance arising from the disk 21 and the rink 13, compensated by pushing the reaction to the rotor 8, so slipping energocredit excluded. The rotor 8 is ripping the reservoir is released from the top. Even at the maximum depth of the rotor 8 to 40...45 cm surface side of the spallation soil tooth 10 coming from its nose and face up in the furrows created by the disks 21 located on the side of each tooth 10. At this critical depth (lateral shearing of the layer from the toe of the working device 11) increases by the amount of penetration of the disks 21, and the energy consumption for the separation of the tooth 10 soil fragment and the drive rotor 8 are reduced.

Rink 13 limits the depth of the rotor 8, smoothes and compacts the soft layer, which reduces convective removal of moisture from the soil. In Fig.1 shows the depth of the rotor 8, close to the maximum.

To adjust the working depth rink instead of 13 can use the reference skis (not pok is explained).

When you change, for example reducing the depth of the tilling rotor 8, a screw mechanism 4 vertically move the beam 5 with the disk working bodies 6, providing the depth of disks 21 at 8...12 see

Due to the placement of the spherical disks 21 before the teeth of the rotor 8 rotary scarifier is not subject to clogging residues and may, at reduced energy consumption steadily without slippage of the tractor and the circulating power in the system MTA to work on clogged, bushy and mulch the agricultural background.

Springing disk 21 and the use of safety shear fingers (bolts) for mounting on the shaft 9 of the clamps 22 with the teeth 10 protects them from destruction at the meeting in soil with stones and similar inclusions.

Rotary scarifier can be attached to the power drive concept (WES), and high power tractors and will be used when softening agrogenic soils and deposits, the area of which in modern Russia is more than 40 million hectares, and when reclamation softening the soil of pastures and meadows.
