The invention relates to agricultural machinery, in particular to the ploughs with rotary rippers, and is intended for primary tillage and digging potatoes, i.e. to perform two basic functions.

The famous "Plow with rotary cultivator" in A. S. No. 245468, IPC AV, 17/00, which is used for tillage. It contains mounted on the frame sequentially passive plow body and the active rotary cultivator with vertical shaft. In the lower part of the rotary agitator is mounted helical blades. Above helical blades are chopping the elements made in the form set at an angle to the axis of rotation of the knives, and the knives are adjustable by the angle of inclination to the axis connecting their upper parts, by means of rods with movable coupling.

The disadvantage of analogue is that the knife employed in cutting mode, the soil particles spend more energy than straps running in a shock mode. The connection to the chopping elements with the help of hinges and rods reduces the reliability of their attachment with the rotating shaft.

Known plow with combined working bodies, also used only for tillage, developed by the Department "strength of materials" CHUMASH in which the knives are located in the upper h�STI rotor, replaced fixed under an angle of 25-30° to the axis of rotation and opposed to each other and evenly spaced around the circumference straps percussion. (M. D. POSKROBKO, I. Y. Steinert, A. S. Ten. Plow with combined working bodies. // Tractors and farm machinery, 1979. No. 4, p. 28)

The disadvantage of this device is intended only for plowing, is the presence of a passive zone between the lifting blades and laths percussion. Managing the degree of crushing of the change of revolutions of the rotor generates, in turn, two drawbacks: the complexity of the design of the drive rotor and the excessive degree of the impact strips on the layer in the area of large radius.

The main Tool for the treatment of alkali soils" by A. S. No. 1031414, IPC A01B 17/00, which is intended for the treatment of alkali soils of heavy texture. It also contains a set of sequentially plow body with a short blade and the active rotor. On the rotor above the helical blades are ripping teeth of rectangular cross section fitted with false plates, fixed on the downlink multi-start helix with angle set to 45°. Clipped plough body layer of the soil is supplied with a single screw on the bottom of the scapula, and the other part with a short blade - Ripper teeth. These parts in vertical ploskostopiju counter each other and actively crumble and mixed.

The disadvantage of this device is the design complexity and excessive grinding of the cultivated soils of medium and light mechanical composition.

Known for "the-Plow potato digger" patent №2236771, which is designed for primary tillage and digging potatoes and adopted us as a prototype. The device comprises a plow body with a short blade and mounted behind him, a rotor with three rows of work items in the form of lifting blades and cores with false plates, and in the third tier posted loosening fingers with patch plates attached to the fingers with the ability to control their situation. The fingers of the second and third tiers for turning at a given angle around its longitudinal axis is attached to a bearing sleeve screw threaded and provided with retainers in the form of a jam nut, rotor hub is provided with a pointer angle. When using the plow-digger in the mode of plowing fingers working and supporting rods of the second and third tiers are set on a downward spiral, i.e. the pads are on the rear faces of the fingers and rods and spare part are down. In operation of the plow potato digger false plate on the working fingers of the second tier are installed on the upward spiral, i.e., on the front faces, and St.�bone portion of the plate is above the finger. Movable pads of the third tier are installed in the vertical plane. In the process, requires the adjustment of the position of these plates with offset longitudinal axes of the plates relative to the rods up to ±45°, and the rotation of the bearing bars at a slight angle from the vertical position of the plates, to improve the separation of tubers and soil.

The disadvantage of this device is the complexity of the configuration of the plow-digger to change its function, due to the need of regulation of a large number of work items and the unreliability of the connection and fixation of the working elements on the carrier sleeve.

Object of the invention is to improve the degree of crushing of the formation, in the main processing of the soil, reduce damage of tubers by digging potatoes, reduce the complexity of conversion of plow when you change its functions, to increase the reliability of structural members

In the mode of tillage technical result is achieved in that the plough for tillage and digging potatoes contains mounted on the frame of a snow plow body with a short blade and located behind it driven vertical rotor bushing in the lower part of the sleeve is placed on multi-start helix working bodies of the first tier - lifting blades, in the middle part fixed working bodies of the second tier - change�chausie elements in the form of loosening of the fingers, at the top of the sleeve mounted working bodies of the third tier in the form of plates, unlike the prototype, to the upper part of the sleeve is rigidly attached to the bearing disk, the second tier consists of loosening the fingers, including the load-bearing rods attached thereto a removable element in the form of wedge-shaped prisms, wherein the supporting rods are rigidly secured to the lower surface of the support disk, and is fixed to the disk portion of the rod is not less than 1/4 part of its length, the third layer is located above the bushing and the platter, thus consists of inclined slats rigidly fixed at an angle to the vertical axis of the rotor, moreover, their lower ends are fixed to the sleeve, the middle portion to the supporting rods and the upper ends are interconnected.

As a result of direct exposure of the thus inclined straps and a wedge-shaped prism layer of intensely crushed and due to the acceleration received by the lumps from the inclined bars in a downward direction, and the other part of lumps from lifting the shoulder blades up, the turnover of the stratum. Wedge prisms are installed on the rotor in the processing of cultivated soils.

In addition, the soils containing a significant amount of vegetation, the technical result of the simultaneous crumbling of the soil and pulverizing roots and stems of plants is achieved in that on the supporting rods close�plautia removable elements in the form of cutting knives.

In the mode of digging potatoes the technical result is achieved by the fact that unlike the prototype of the second tier consists of bearing rods, supporting rods and inclined beater straps attach digging up the plate in the form of a polygon, the lower side of which is set with increasing from the axis of the rotor by a gap, and lateral side parallel to the axis, and digging up the plates overlap the area of the working bodies of the second and third tiers that protects the tubers from damage.

Thus, for translation of the plow from the main processing mode to the mode of digging tubers on the rotor is obtained by replacing the removable digging elements on the plate that reduces the complexity of conversion, in comparison with the prototype.

The problem of improving reliability of a design is performed through: strict assignment of not less than 1/4 of the length of the carrier rod back plate, a rigid connection of the lower part of the sloping planks to the bearing sleeve, in the middle part of the connecting rod bearing and strips together, and in the upper part of the additional connecting straps between them. Pinning digging plate extreme points horizontally to the supporting rods, the end points of the vertical to the oblique straps also enhances the rigidity of the structure.

Thus, ensuring that�aceveda the achievement of the technical result when the device is in the mode of ploughing or digging potatoes.

Consider an implementation of the invention on the example of a single-hinged plow.

The device comprises a plow body 1 (Fig. 1) with a short blade attached the bar to the frame. The frame is the main load-bearing beam 3, 4 longitudinal and 5 transverse bars, and a frame 6 of the hinge mechanism, with the housing 1 on the beam 3 with a distance of 650 mm from the toe near to the centre of rotation in the direction of motion and 350 mm from the line of field shotgun is mounted a rotor 2. The rotor shaft 7 by means of the driven pulley 8, V-belts 9, a driving pulley 10, gear 11, the support-shaft 12 receives the rotation from PTO shaft of the tractor. The working parts of the rotor with the shaft 7 (Fig. 2), the pulley 8 rotates on bearings mounted in the bearing housing 13. On the lower part of the shaft 7 of the rotor mounted bushing 21, fastened to the shaft by a key. On the surface of the sleeve 21 and backing plate 16 are rigidly secured to the upper part of the sleeve 21, and is fortified with three levels of work items. In the lower part mounted three lifting vanes 22. The lower edge of the blades 22 is sharpened and can cut n�CVO. The blades are located at a triple-threaded helical line with the angle of elevation of 25°. To the lower surface of the support disk 16 is rigidly secured a bearing bars 17, and is fixed to the disk portion of the rod is not less than 1/4 part of its length. At the ends of supporting rods 17 are made two holes. A wedge-shaped prism 18 (Fig. 3) is made with a cross section in the form of an equilateral triangle with sides of 20 mm of steel 65G for "GOST 14959-95. Hire from spring carbon steel".

For fastening of the front faces of the carrier rod and the working edge of the prism parallel to each other on the outermost holes on the supporting rods rigidly secured thereto ear 20 (Fig. 2) thickness equal to the thickness of the strap. For fastening of the wedge prisms and the cutting blades to the supporting rods are pins 23 (Fig. 3 and 4) and nuts with washers 19 (Fig. 2), and the distance between the pins is equal to the distance between the holes on the rods 17. Depending on the characteristics of the soil for its quality processing on the rods can be mounted wedge-shaped prism 18 (Fig. 3) or the cutting blades 24 (Fig. 4). The working part is inclined beater bars 15 (Fig. 2), is rigidly fixed at an angle to the vertical axis of the rotor is located above the support disc and is the third tier of the working bodies. Inclined mobile strap lower end secured to the hub 21, the average �part fixed to the supporting rods 17, and the upper ends connected to the ring 14.

The device to operate in the mode of digging potatoes is adjusted after removing the work item on support rods (wedge-shaped prisms or cutting knives). Then by means of connecting elements (bolts) 26 (Fig. 6) at two holes of the supporting rods 17 (Fig. 2) and two hole beater bars 15 front beater bars are fixed digging plate 25 (Fig. 5, 6) in the form of a polygon, which cover the area of the working bodies of the second and third tiers. Closing the working elements of the intense action flat digging plate protects the tubers from damage (Fig. 6).

To eliminate the possibility of crushing big lumps of soil, tubers and foreign bodies between the lower edge of the digging plate and the upper surface of the lifting blades should be increasing from the axis of rotation of the rotor gap. The widening gap is provided by the shape and dimensions of the digging plate. Digging plate 25 (Fig. 5) is a hexagon irregular shape. The hexagon structurally important are the four sides. Two sides parallel to the axis of the rotor, adjacent the inclined beater bar repeats its inner contour, the lower side makes with a horizontal plane an acute angle of at least 35°. The minimum value of the angular �Azora at the junction of the bottom side of the digging plate and the upper surface of the lifting blade will be above the line of maximum lift, equal to 25°. It is equal to 10° (Fig. 6). The efficiency of the plough is in the process of digging potatoes provides a combination of angular and linear gap near the bushing is equal to 40 mm. On digging up the plate, drilled two holes for bolted connection with bearing rods and two with inclined beater bars. On the rods and straps the holes are drilled at their ends at a distance sufficient to ensure the necessary rigidity of the fixed digging up the plates.

Patented combo tool for digging potatoes has the following main specifications: working width of the plow body 350 mm rotor 150 mm. Rotation to the rotor shaft from the power takeoff (PTO) is transmitted through a reduction gear and a belt drive. When you switch on the gearbox PTO 540 rpm at rated engine speed of the tractor, a rotor speed of 300 rpm When switching to 1000 rpm, the rotor rotates with a frequency of 600 rpm.

In the main processing of the rotor depending on the condition of coming to tillage can be equipped with two kinds of working bodies. If the soil is cultivated, on bearing rods 17 (Fig. 2) are fixed wedge-shaped prism 18, salesadmin, weedy fields or weeds when sealing of green manure on the supporting rods 17 are fixed removable elements in the form of cutting �OGA 24 (Fig. 2-4). When plowing gearbox PTO included 540 rpm, tractor engine running at rated speed.

The combined lead instrument in working position by adjusting the depth of plowing and buried him. During the working process of soil formation, undercut passive housing, is supplied to the rotor. The lower part of the reservoir from the ploughshare and the lower part of the blade comes to lifting blades, crumble them and rises. The other part of the reservoir passes through the blade and is supplied to the elements of the second and third tiers. The soil is destroyed by the wedge-shaped ribs of the prism, thus slanted slats. As a result of direct exposure of the thus inclined straps and a wedge-shaped prism layer of intensely crushed and due to the acceleration received by the lumps from the inclined bars in a downward direction, and the other part of lumps from lifting the shoulder blades up, the turnover of the reservoir.

On soils containing a significant amount of vegetation (salesadmin, weedy fields or weeds when sealing cover crops), simultaneous crushing of soil, crushing the roots and stems of plants and turning the soil are achieved by the fact that the supporting rods fixed removable elements in the form of cutting knives.

To operate the device in the mode of digging potatoes working elements on support rods (�lunovidnye prism or cutting blades) to remove and replace them by means of connecting elements (bolts) 26 (Fig. 6) on the lifting blades 22, the bearing holes of the rods and thus laths, fastened digging plate (25) in the form of a polygon. Gearbox PTO is switched to the rotational speed of 1000 rpm at rated engine power of the tractor. Conducted tests of the prototype found that the intensity of the process, when digging plow-digger 2.0-2.5 times lower than when plowing. So decreasing the fuel supply to the engine is adjusted for operation with a frequency below nominal. Depending on the condition of the soil of the ridge the necessary frequency of rotation of the rotor 300 to 400 rpm.

The digging of the potatoes planted in a raised bed technology, is made with a single row as follows: tractor unit with the plow, moving across the field, undermines the passive case tuberous crest to a depth slightly more than the depth of the bottom of tubers, lifts the layer, and partially destroys at a certain angle and speed, equal to one-half the speed of the unit, serves on the rotor, rotating with a certain angular velocity. The reservoir is subjected to a shock of digging plates of the rotor, which throw the tubers on the surface of the field to the right side of the aisle stripe unit 1-1,5 m. Due to the design features of the digging plate, bookmark�featuring in that its outer contour parallel to the axis of rotation, the impact of the rotor per revolution of the reservoir is minimized. Depending on the lifting height on passive moldboard surface of the different parts of a pile of potato crest these parts get different range in a direction transverse to the direction of movement of the unit. The soil of the ridge evenly routed from the rotor to the full width of the strip. Thanks to the unfolding of the heap with a thin layer is achieved, the visual openness of the separation of the tubers from the soil and foliage, which facilitates their further collection.

The use of combined tools for digging potatoes enables tillage to provide high-quality processing of various composition and properties of soils, digging potatoes not save the damaged tubers, reduce the complexity of conversion of plow when you change its function and to reduce the time spent on Troubleshooting.
