Description

The invention relates to the field of agricultural machinery, in particular to devices for continuous subsurface tillage, including in fields with many sites that do not allow moisture to precipitate.

Known devices designed for deep loosening of soil at 40-80 cm: chisel plow P4-4.5; NR-80 B, ChKU-4, KZU-03 V cultivators-deep rippers, including chisel-like paws (see Agriculture systems in the Krasnodar Territory for 1990-1995 and for the period until 2000: Recommendation. VASKHNIL, All-Russian Branch, Krasnodar Research Institute agriculture named after P.P. Lukyanenko, Kuban Agricultural Institute. Krasnodar, book publishing house, 1990, p. 59, 128, 260).

The disadvantages of these units are low technological capabilities, high energy consumption and metal consumption.

Also known mounted hinged plow, including a rectangular pipe, welded frame. It is equipped with a three-point linkage system on the tractor and adjustment of the depth of tillage in the form of support wheels mounted at different heights. Racks are fixed on the frame, in the lower part of which lancet legs are installed. They are divided in half, each half is made with a rectangular cut, pivotally mounted on the bottom of the rack, have a T-section and are located at an angle to the horizontal. Racks have the ability to fold and unfold, and with their subsequent fixation (see RF patent No. 2144749).

The disadvantages of this device are high energy costs, low operational ability when processing the soil (due to the lack of a bit between the legs, due to the rapid wear of the cutting edges, due to breakdowns of the working bodies when meeting with solid objects in the form of stones and scrap metal), and also poor-quality crumbling of the soil, and low technological capabilities.

The closest in technical essence and the achieved economic effect is “Device for subsurface tillage” according to patent RU No. 2404560, which includes a welded two-beam frame, equipped with a hitch system, support elements arranged in a checkerboard pattern with working bodies containing racks equipped with a circular shaft in front with a bent end, on which a round-cut bit with a sharpening and soldering of a cermet alloy and paws fixed on a hinged shaft behind ykoy.

The disadvantages are: high metal consumption, design complexity and high energy costs.

The technical solution is to reduce the metal consumption, simplify the design, as well as reduce energy costs and increase operational reliability.

The technical solution is achieved by the fact that in the device for subsurface tillage, including a welded two-beam frame, equipped with a hitch system, support elements arranged in a checkerboard pattern by working bodies having racks with a bent end, with chisels with sharpening and soldering from a ceramic-metal alloy and with paws , according to the invention, racks with bent ends are made in the form of an integral part from a round pipe with a diameter of 90-95 mm and have an oblique cut, and the bits are made in the form of elliptical plates and two ear-shaped brackets covering the oblique slice of the bent end of the rack and securing with a finger, and two flat brackets are rigidly mounted behind the bend of the rack, between which is inserted a bracket rigidly connected to the paw, which is made semicircular, with a top sharpening and has agitators in the form of metal strips partially cut out at the end of the back of the paw and bent at an angle of 40-50 °. The upper part of the rack is equipped with a rigidly mounted plate bracket for attaching to the frame. The front desk is equipped with a protection (oral) secured with two screws.

The new elements are that racks with bent ends are made as an integral part from a circular pipe with a diameter of 90-95 mm and have an oblique cut, and the chisels are made in the form of elliptical plates, with soldering and two ear-shaped brackets covering the oblique cut of the bent end of the rack and attached with a finger, and behind the bend of the rack two flat brackets are rigidly fixed, between which a bracket is inserted that is rigidly fixed to the paw, while the paw is made semicircular, with an upper sharpener and has agitators, you filled in the form of strips of metal, partially cut out at the end of the back of the paw and bent at an angle of 40-50 °, the upper part of the rack equipped with a rigidly mounted plate bracket for attaching to the frame, and the rack is equipped with a front guard (on-board) secured with two screws .

The novelty is that during operation the bit is easier to penetrate into the soil, the stand has less resistance due to the round shape, the mass of the working body is less than the prototype, it is simpler than the design of the agitator and paws, which have the ability to easily and quickly replace.

The invention is schematically shown in the drawings: in FIG. 1 is a top view soilless tillage device, in FIG. 2 is a section A - A of a working body, in FIG. 3 is a rear view of a working body, in FIG. 4 is a top view of a working body.

The device for subsurface tillage contains a welded two-beam frame 1, equipped with a hitch system 2, and support elements 3. On the frame 1, the working bodies are staggered, comprising a rack 4 made of a pipe with a diameter of 90-95 mm (Fig. 2) with a bent end and equipped on top with a rigidly mounted plate bracket 5 with holes for bolt fastening on the frame 1. On the bent end of the rack, an oblique cut 6. is made at an angle α = 25 °. soldering 8 and ear-shaped brackets 9 with holes for fastening with a finger 10 to the rack 4. The lower plane of the bent end of the rack 4 is located at an angle β = 10-13 ° to the horizontal. The front of the rack 4 is equipped with a protection 11 (normal), secured with two screws 12, and behind the bend of the rack 4 are two flat brackets 13 with holes, between which the bracket 14 of the foot 15 is mounted. The bracket 14 is rigidly fixed to the foot 15 vertically with an offset from axis and with the possibility of fixing it in the same plane with the lower plane of the bent end of the rack 4. Paws 15 have, agitators 16 made in the form of strips of metal cut partially in the end of the back of the paws and bent at an angle of 40-50 °.

The device operates as follows.

When plane-loosening, the racks 4 are fixed on the frame 1 by means of the flat brackets 5. The bent ends on the sections 6 are equipped with chisels 7, and in the flat brackets 13 a bracket 14 with a semicircular paw 15 is fixed, then the frame 1 is hung on the tractor, and with the help of the supporting elements 3 it is adjusted processing depth. In the field, the frame 1 is lowered using the linkage 2 and the tractor hydraulic system. When the unit moves, due to the elliptical shape of the bits and hard soldering, the introduction of working bodies into the soil is ensured, including compacted (for example, drought). The diameter of the rack 4, equal to 90-95 mm, provides at a speed of 8-15 km / h the minimum soil resistance (determined experimentally see certificate on state registration of computer programs No. 20100610878; 2010610879; 2010610880 from 01/28/10) and makes the soil digging, which on both sides of the rack 4 is treated with a semicircular paw 15, which reduces soil resistance and is able to self-sharpen. The cut layers, running onto the agitators 16, crumble. Vertical fastening with an offset from the axis of the bracket 14 to the foot 15 is necessary to approximate the sharpening of the foot 15 to the rack 4.

Deep loosening is carried out with the legs 15 removed.

Such a combination is possible: the placement of the working bodies for deep and planar loosening, the processing depth is regulated by the supporting elements 3 and using the holes on the bracket with which the racks 4 are equipped.

The proposed device provides a reduction in metal consumption, ease of manufacture, and also provides a reduction in energy costs and operational reliability.
