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; cultivators-deep-rippers of the type HP-80 B, ChKU-4, KZU-03 V, 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.

A mounted plow is also known, including a rectangular tubular, welded, equipped with three-point hitching systems for the tractor and adjusting the working depth in the form of support wheels mounted at different heights, a frame with racks fixed to it, with lancet legs mounted on its bottom. The lancet paws are divided in half, and each half with a rectangular cutout in it is pivotally mounted on the lower part of the lamellar, having a T-section and located at an angle to the horizontal, struts with the possibility of folding and unfolding and with subsequent fixation (see RF patent No. 2144749).

However, the disadvantage of this device is the 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, thrown metal) as well as low quality of crumbling soil, and low technological capabilities.

The closest in technical essence and the achieved economic effect is a device for non-soil tillage (decision to grant a patent on application No. 2009101717/21 (002140)), including a welded two-beam frame equipped with a hitch system and support elements, placed on the frame mounted in staggered working bodies containing racks equipped in front with a round shaft with a bent end, on which a round bit with a sharpening and brazing of a ceramic-metal alloy is put on and fixed And pointed legs, fixed on the pivot shaft from behind the counter.

The disadvantages are: low technological capabilities (one operation - flat cutting), high energy costs and high material consumption.

The technical result is the expansion of technological capabilities, reducing energy costs, increasing operational reliability and reducing material consumption.

The technical result is achieved by the fact that in the device for subsurface tillage, including a welded two-beam frame equipped with a hitch system, and supporting elements, moreover, the working bodies arranged in a checkerboard pattern are mounted on the frame, containing front axle shaft with a curved end, on which is worn a cylindrical bit sharpened with cermet welding, racks and articulated legs, according to the invention, the bit at the bottom and rear is equipped with a platform with a welded bracket in the idea of a spline element for mounting and fixing a paw equipped with a spline hole, the bit having a groove into which a flattened shaft end and a pivot mount are inserted, wherein the paws consist of two half-holes made in the form of plates with double-sided sharpening, with the left and right half-holes to establish the necessary width of the working body, and the cermet soldering has the form of a segment.

The new elements are that the bit at the bottom and rear is equipped with a platform with a welded bracket in the form of a splined element for installing and fixing the legs, provided with a splined hole, the bit having a groove into which the flattened shaft end and the hinge are inserted, while the legs consist of two half-holes made in the form of plates with double-sided sharpening, and the left and right half-holes have the ability to set the necessary width of the working body., moreover, the cermet soldering has the form of a segment.

The novelty is that due to the pivotally fixed bit, cylindrical shape of the bit, upper sharpening, soldering, the resistance to the working body is reduced and the duration of work without sharpening is increased, as well as the ability to change the width of the gripper of the paw will allow you to perform the following work: chiseling with worming, chiseling with a little opening half and flat cutting.

The invention is schematically shown in the drawings: in figure 1 - device for subsurface tillage, top view, in figure 2 - section aa, in figure 3 - view B.

The device for subsurface soil cultivation contains a welded two-beam frame 1 equipped with a hitch system 2 and support elements 3. On the frame 1 are mounted staggered working bodies containing, equipped with a front shaft 4 of circular cross section with a bent end, which is worn with a ceramic-metal brazed 5 cylindrical chisel 6, racks 7 and legs, consisting of two half-arms left 8 and right 9. Chisel 6 at the bottom and rear is equipped with a platform with a welded bracket 10 in the form of a spline element for installation and fixation and half-holes 8 and 9. The bit 6 has a milled groove 11, into which the flattened end of the shaft 4 and the hinge mount 12 are inserted. The legs 8 and 9 are made in the form of two plates with double-sided sharpening, are provided with splined holes and can be set to the required working width body. Cermet soldering 5 has the form of a segment.

The operation of the device is as follows: for example, to perform chisel cultivation with worming in fields that do not allow moisture to pass, the device for subsurface tillage works as follows. The half-holes 8 and 9 are installed along the direction of movement under the stand 7 behind the bit 6. For this, a bolt is unscrewed from the bracket 10, which then, after reinstalling, the half-holes 8 and 9 are again secured with the help of splined holes. For flat-cutting treatments, similar work is carried out, only half-holes 8 and 9 are set with different angles of their solution, depending on agrotechnical tasks. When the unit moves along a corral set to the required processing depth using the support wheels 2, the chisel 6 and the half-holes 8, 9 work as non-stocking organs. In this case, the shaft 4, made in the form of a club, provides the front with a decrease in drag. The hinge 12 self-adjusts the bit 6 and gives it vibrations, which also ensures a decrease in soil resistance.

Due to the upper sharpening of the bit 6, segment soldering 5, the resistance to the working body is reduced and the duration of work without sharpening is increased, as well as due to the double-sided sharpening, half-openings 8 and 9.

Due to the possibility of changing the working tool working width with the help of half-holes 8 and 9, the ability to perform the following work appears: chiseling with worming, chiseling with a slight opening of the half-holes and plane-cutting tillage.

The proposed device for subsurface tillage is a universal technical tool for planar loosening of the soil and for deep loosening (chiseleva), it will reduce energy and labor costs.
