Description

The invention relates to agricultural machinery, in particular to tillage working bodies, and can be used for deep loosening of the soil.

Known working body for tillage, including a rack with a blade, tier and inclined plowshares with cutting edges, in which, in order to reduce the energy intensity of deep loosening of the soil, the rack is made in the form of two plates with stepped blades that are inclined outwardly relative to each other, and the plowshare are located between the rack plates and are made with shaped protrusions (SU, copyright certificate No. 650530, M. Cl. A 01 B 13/16. Working body for tillage // B. D. Shishkarev, V. M. Zubets, V. I. Belkovsky and Sh.I. Brusilovsky. 03.03.1977, op Released 03/05/1979).

The disadvantages of the described organ include clogging of the space between the rack plates and shares of plant and root residues, soil and soil, the complexity of the design and high energy costs.

The closest analogue to the claimed object according to the set of essential features includes the working body of the cultivator, including a stand with a fixed tip on it, in which, in order to reduce traction resistance and improve the quality of soil treatment in curved sections, the stand is made in the form of links arranged one after another, which are interconnected by means of vertical hinges (SU, copyright certificate No. 671754, M. cl. ² A 01 B 13/00. Working body for tillage // Yu.M. Serikov, L.G. Prpryan. Claimed 09/14/1976 , about ublikovano 05/07/1979).

The disadvantages of the analyzed working body, adopted as the closest analogue, are the low efficiency of soil crumbling and the poor operational reliability of the vertical joints.

The invention consists in the following. The problem to which the invention is directed is to increase the efficiency of loosening and crumbling of soil and soil on complex terrain.

The technical result is a reduction in energy consumption, simplification of the design, an increase in the loosening zone of the arable layer and the arable horizon.

The specified technical result is achieved by the fact that in the known working body of the cultivator, including the rack in the form of links arranged one after another with a tip fixed to the lower cut, according to the invention, the rear link is made in the form of an elastic plate, the lower end of the plate is mounted on the back of the rack above the tip moreover, the plate is given the shape of an equilateral trapezoid, the wide base of which is oriented upwards of the knives, in addition, each tip is represented by a chisel, mounted at an angle to the horizon and the rack.

Due to the fact that the rear link is made in the form of an elastic plate and is installed at an angle to the rack at its rear section, the above technical result is achieved.

The invention is illustrated by drawings.

Figure 1 presents the working body of the cultivator, a side view, in the initial, inoperative position of the elastic plate.

Figure 2 is the same front view.

Figure 3 is the same side view, when exposed to an elastic plate with soil and soil.

Information confirming the possibility of the claimed technical solution is as follows.

The working body of the cultivator (see Figs. 1-3) contains a rack in the form of links arranged one after another with a tip 2 fixed on the lower cut. The tip 2 is represented by a bit mounted at an angle to the horizon and the rack. The back link 3 is made in the form of an elastic plate. Link 3 can be made in the form of a package of elastic plates. The lower end of the link plate 3 is mounted by means of fastening sections 4 and 5 on the rear part 6 of the rack above the tip 2. The link plate 3 is given the shape of an isosceles trapezoid. The wide base of the trapezoid (see figure 2) link 3 is oriented upwards, i.e. towards the mounting part 7 of the rack. The mounting part 7 of the rack 1 is equipped with cans 8. In the cans 8 and rack 1, the holes 9 are for connecting fasteners with the frame of the tillage implement. The front part 10 of the rack 1 is provided with a curved cutting edge 11. The tip 2 has a blade 12.

The working body of the cultivator process performs as follows.

Tillage medium and arable units are regularly prepared (according to zone recommendations) for work. On complex sections of any configuration and on slopes with slopes of up to 20 °, the unit moves with a working speed of at least 7-15 km / h. At a given depth during steady state, the cutting edge 11 of the rack 1 cuts the stubble, roots and plant debris in the upper arable layer. A two-sided blade on the front part 10 of the rack 1 and the rear link 3 perform a vertical, and then a slit with inclined walls. The tip in the form of a chisel on the bottom cut of the rack 1 holds the rack 1 and link 3 at a given depth, at the same time, this bit, loose soil, forms a focal reservoir. Simultaneously with the cutting edge 11 of the rack, the blade 12 and tip 2 participate in the technological process. The two-sided knife on the frontal part 10 performs a vertical slot with loosened walls, and the bit of the tip 2 loosens the arable horizon and performs an equivalent reservoir remote from the top layer to accumulate excess moisture.

When performing the described sequence after the passage of each rack 1 of the cultivator on the surface of the field (plot, meadows, deposits), a vertical gap with torn inclined walls is formed.

This is facilitated by the elastic plate of the rear link 3. Inclined walls connect the focal reservoir at the bottom of the loosening zone. When processing slope lands, storm pockets and spring water during snowmelt, irrespective of the direction of suspension of the slits and the loosening zone along the vertical slit and inclined walls, are discharged into the focal reservoir.

A gable ridge, formed between inclined walls on slopes, holds a sufficiently large volume of water. This ensures replenishment of soil moisture reserves and eliminates solid runoff on both non-irrigated and irrigated lands. The back link 3 due to its elastic qualities intensively crumbles a layer of soil in the zone of passage of the rack.

Exclusions of overhanging plant - root residues on the rack and inclined faces of the plate of the elastic element, as well as the rational geometry of the working body of the cultivator as a whole provide a reduction in energy costs for the work process.
