The invention relates to agriculture, in particular to tillage machines.

Known tool for extracting rhizomatous residues from the soil, which, for better separation from the soil and release them vytesyvali of rotor teeth, the rotor is provided with a vibrator, and the teeth are spring loaded (ed. SVID. THE USSR 1565387, AV 39/18).

The lack of guns is the design complexity, the inefficiency of rotor teeth to extract the roots of garden trees (perennial plants).

It is known tool for extraction of root residues from the soil containing the story sweeps paws, Dubovy the rotor rotating opposite to the motion of the gun (bottom-up), an eccentric mounted on the casing extractor with slots for the teeth of the rotor, a beater with elastic blades and hopper (ed. SVID. THE USSR №183513, AV 39/18).

The main disadvantage of the gun is enveloping stands clutches of plant remains, unsatisfactory exemption of rotor teeth in the processing of wet soils, their pinched between the tooth and the casing and the overhang on the bottom, quick clogging of the rotor.

The closest in technical essence to the claimed tool is selected as a prototype device for processing the soil and the extraction of rhizomes on the bus. SVID. THE USSR №1607706, AV 39/18. The device comprises a frame with at�soedinitelny device, the rotor shaft and vytesyvali C-shaped teeth on it, rotating opposite to the motion of the tools, the mechanisms of the drive rotor. In addition, there are spurs working bodies, ratchet, are located at the ends of the drum, and the drive mechanisms in the form of hydraulic cylinders, the rod of each of which is associated with the clutch.

A disadvantage of the known device is that in the soil at the same time buried (buried) the entire row of teeth. Simultaneous penetration of the whole number of teeth is difficult and causes harmful vibrations mechanisms hitch and all utilities. When the spacing of the teeth on the width of the drum of 1.5 or less quantities of processing depth, the number of teeth will unload the soil. Rhizomes, dropped one row of teeth, re-captured sinking into the ground teeth of the other row. The device works with flaws as it goes, as it goes some way without burying the entire range of teeth and not extracts of rhizomes, do not loosen the soil. A rotor comprising a series of teeth rigidly fixed, has a high energy to work.

An object of the invention is to ensure the sustainability and quality of the process of extracting from the soil of root residues perennial crops and reducing energy consumption for deep loosening of soil.

The technical problem is solved in that in the rotary visivel-Glubokiy�the piece, containing a frame with a connecting device, the rotor shaft and vytesyvali teeth on it, rotating opposite to the motion of the tools, the drive mechanisms of the rotor according to the invention the teeth of the rotor, located in the same plane of rotation, mounted on a movable in the plane of rotation of the flange, the yoke of which is associated with the rotor shaft by means of elastic elements mounted in the annular cavity between the mating surfaces of the cage and the shaft, containing respectively on the inner and outer mating surfaces of the longitudinal ribs placed at the same angular offset to the cage and the shaft, wherein the length portion of the ring cavity unloaded rotor filled elastic elements, before the ribs of the shaft, at least two times more than in front of the rib cage, in addition, the teeth of the rotor taken along a helix with an angular offset on adjacent flanges at least 45° and in front of the rotor in the middle of the lanes, passing between his teeth, mounted disc blades with leashes.

In addition, leashes circular knives mounted on the support beam, adjustable in height, in the rear part of the rotor between the teeth are grooved, tapering downward sloping plates containing rounded longitudinal ribs of different heights, with leashes flaps are associated with carrier balconies� articulated with restriction lowering them, and the lower part is mounted to the rear of the body of rotation of the rotor.

The invention is illustrated by drawings.

Fig. 1 shows a rotary visivel-chisel, side view, Fig. 2 - the same, top view, Fig. 3 - section shaft and the shell with elastic elements.

Rotary visivel-chisel comprises a frame 1 with a connecting device 2, Dubovy the rotor 3 is composed of left and right sections, made in the form of a shaft 4, which contains sections with longitudinal ribs 5, which has a movable(in the plane of rotation of rotor teeth)clips with 6 longitudinal ribs 7 on their inner surfaces and the flanges 8 on the outside, which are mounted on C-shaped teeth 9, that is, those in which the working edge from the toe to the fastening part has a shape of a concave arc. The ribs 5 on the shaft 4 and the rib 7 on the holder 6 is placed at the same angular offset.

In the annular cavity between the mating surfaces of the shaft 4 and the holder 6 are mounted elastic elements (dampers): in front of the ribs 5 of the shaft 4 of the dampers 10 and the front edges 7 of the cage 6 - dampers 11. The dampers 10 and 11 are in the form of rubber rods of cylindrical shape. The length of the cavity filled with uncompressed elastic elements 10, in front of the ribs 5 of the shaft, at least two times greater than on plots with the dampers 11 in front of the ribs 7 of the unloaded rotor 3, the teeth to�which are not in contact with any obstacle, including the support surface. That is, when the same form of dampers before each rib 5 at least two times more than in front of the rib 7.

In the grooves of the uprights 12 of the frame 1 is fixed a beam 13, height-adjustable installation. It fixed leashes 14 circular knives 15 placed in front of the rotor 3 in the middle of the lanes, passing between his teeth 9. The penetration of the blades 15 is adjustable by a screw mechanisms 16, which provides vertical movement of the beam 13 in the grooves of the uprights 12.

On the racks 17 of the frame 1 is fixed to carrier beam 18 is pivotally mounted by leads 19 and are fixed to narrowing down sloping grooved plates 20 and 21 with rounded longitudinal ribs of different heights. Such an arrangement of ribs improves the orientation of the segments of roots along the flap and the conditions of their downward movement. Turn (down) flaps 20 and 21 is limited by a stop (not shown) in the pivot joint of beams 18 and 19 leashes with flaps 20 or 21. The lower ends of flaps placed at the rear of the body of rotation of the rotor 3, are related to the soil only when it is deepened, when in contact with the surface of the soil and shaken, moving on to its irregularities.

The mechanisms of the drive rotor 3 contain cardan transmission 22 from PTO shaft (PTO) of the tractor to step-down the cylindrical gear 23, the drive train 24 on the worm redu�tor 25, mounted on the platform 26 of the frame 1. The ends of the left and right sections of the rotor associated with the shaft of the gear via a toothed couplings (not shown).

Working depth rotor is controlled by the reference ski 27 mounted on the uprights 28 adjustable height of their attachment to the frame 1 and the movement of the beam 13 in the grooves of the uprights 12.

When vytesyvali-chisel disc blades 15 in front of the teeth 9 in the bands between them cut the seam with plant residues on the surface and tree roots in the soil, which facilitates their extraction from the soil. Torque from the tractor PTO through mechanisms 22...25 of the actuator is transmitted to the section of the rotor 3 rotating in the direction of movement of the machine (bottom-up), and the teeth 9 of the rotor 3 is alternately immersed in the soil. Immersion and movement of the tooth 9 in the soil ferrule 6 of his ribs 7 compresses the elastic elements 10 placed in front of the ribs 5 of the shaft 4. During compression of the damper 10, the angular velocity of the cage 6 with the tooth 9 is smaller than the shaft 4 of the rotor 3. Because the resistance of the soil to movement of the tooth 9 is not constant, the force and the amount of compression of the dampers 1 are Canceled, and thus the tooth 9 in the soil oscillates in the plane of rotation. In this case, the resistance of the stratum movement of the tooth 9 and the torque to drive the rotor 3 is reduced. Before the release of the tooth 9 of the soil load on it is reduced - due to spallation �ochonogor fragment, the dampers 10 are straightened, and the yoke 6 with a tooth emerging from the soil, rapidly rotated in the direction of rotation of the drum 3 to the stop (cob) of the ribs 7 of the cage 6 in the elastic elements 11 located at the rear of the ribs 5 of the shaft 4. The dampers 11 prevent hard impact of the ribs 5 and 7. When shaking the teeth roots (plant residues), extracted from the soil, flushed with the previously released from the soil of the tooth 9, fall on a grooved inclined plates 20 and 21 (or on their rounded edges), and the incline moves beyond the body of the rotor (the zone of immersion of the teeth in the soil), which eliminates re-entering the roots of the teeth 9. The flaps 20 and 21, moving on a rough surface of the soil, constantly shaken that facilitates the slide of plant residues on them. In transport position the gun lowering of the flaps 20 and 21 is limited.

The proposed implementation of vytesyvali-chisel reduced power consumption for deep loosening of soil, improves the extraction process on the surface of the field of root residues, helps rid the teeth of the rotor, prevents re-ingestion of residues on the teeth.

SUBSTANCE: invention refers to agricultural machinery. Mower for vegetation is made with an ability to move in a direction through the vegetation. The mower contains a number of knife devices located apart from each other. Each knife device has at least one cutting-off part working in the direction of the said distance. Stalks of vegetation in cross section vary in thickness or diametre. Mostly weeds and unnecessary croppers have larger thickness. The required croppers have stalks of smaller thickness or diametre. The distance between the knife devices is shorter in a certain place than the greater thickness or diametre at the site of operating of the cutting-off part. When moving through the vegetation the cutting-off part cuts or damages the stalks of greater thickness, which die afterward. The cutting-off part mostly does not damage the stems of smaller thickness and therefore they remain mostly undamaged and continue growing.

EFFECT: mower provides effective weeds and other unnecessary crops destruction on large areas of agricultural land.
