Description

The invention relates to agricultural machinery, in particular to the working bodies of tillage tools designed to combat soil erosion.

Known working body of soil slitting, made in the form of a rack with a knife, in which, in order to create open continuous slots without protruding soil rollers, the knife is made in the form of a dihedral vertical wedge with a curved-concave cutting edge; in order to reduce soil falling asleep in the rear part of the knife, leveling plates are pivotally fixed, the angle of attack of the knife is made variable in height; the leveling plates are made curved outwardly (SU, copyright certificate No. 389735. Mcl A 01 B 13/16. Working body for soil cleavage // V.N. Sidorenko. Declared 12/23/1971, published 11/07/1973).

The disadvantages of the provided working body include the low efficiency of the slots made on the slope sections and the short service life of the cutting edge of the knife.

The closest analogue to the claimed object according to the set of essential features includes a working device of the slotter containing a stand, removable knife elements and a chisel on the bottom edge of the stand, in which, in order to simplify the manufacturing technology, the stand is made in the form of sidewalls and liners fixed on the inside with the formation there is a groove between them, and each removable knife element is made in the form of a flat oblique parallelepiped and is installed in the rack groove with the possibility of its movement and fixing, and the cutting edge The acute angle of the upper removable member is located at the front of the cutting edge at the obtuse angle of the subsequent removable member; the bit is provided with a longitudinal groove; in order to expand the functionality, the non-working edges of the inserts of the upper removable element are placed in front of the cutting edge at a dull angle of the subsequent removable element; the bit is provided with a longitudinal groove; in order to expand the functionality, the non-working faces of the liners of the upper removable element are vertically placed in the sidewalls of the rack (SU, copyright certificate No. 1734586. M.cl. ⁵ A 01 B 35/26. Working body for slitting // A.P. Sapunkov, A. M. Saldaev. Declared April 24, 1990, published May 23, 1992).

The presence of removable elements of the knife and chisel on the lower edge, undoubtedly, increases the technological reliability of the working body. However, the narrow slots performed by him are ineffective for intercepting and retaining natural and artificial sediments on slope massifs.

The essence of the claimed invention.

The task to which the claimed technical solution is directed is the expansion of functionality.

The technical result is a decrease in runoff and an increase in the efficiency of tillage while maintaining a stubble background on soils subject to wind and water erosion.

The specified technical result is achieved by the fact that in the known organ of the slotter containing the rack in the form of sidewalls and liners fixed on the inside of each of them with the formation of a groove between them, removable elements mounted on the front part in the rack groove with the possibility of movement and fixing and equipped with a longitudinal groove on the upper face, a detachable bit on the bottom edge of the rack, according to the invention, each sidewall is provided with an angle-shaped one made in the form of a curved knife with a cutting edge on the front part, p When in use uglosnim formed from the local part of sidewalls curved laterally from the rack.

Due to the fact that the rack is equipped with oppositely mounted angle films, the front parts of which are equipped with cutting edges, the above technical result is achieved.

The invention is illustrated by drawings.

Figure 1 presents the working body of the alkali, front view.

Figure 2 is the same plan view.

Figure 3 is the same side view.

In figure 4. section AA is shown in FIG. 3, a horizontal section of a rack of an organ of the slotter, a removable blade and an insert.

In Fig.5 is a section bB in Fig.3, a horizontal section of the rack and angles with the cutting edges on the front.

In Fig.6 is a section bb In Fig.3, a horizontal section of the lower part of the sides of the rack, liner and removable blade.

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

The working element of the slotter contains a stand 1 and a detachable bit 2. Stand 1 is made in the form of left and right along the side of the working body sidewalls 3 and 4 and liners 5 and 6 fixed on the inside of each of them. Inserts 5 and 6 between sidewalls 3 and 4 form a groove 7. On the front of the rack 1, in the groove 7 between the sidewalls 3 and 4, a removable element 8 is installed with the possibility of movement and fixation. The lower part of the removable element 8 is placed in the groove on the upper face of the detachable bit 2. The detachable bit 2 is located on the bottom edge of the rack 1.

Each sidewall 3 (4) is equipped with an angle-measuring 9 (10). The angles 9 and 10 are made in the form of curved knives with cutting edges 11 and 12 on the front part. The angle 9 (10) is formed from the local part of the sidewall 3 (4). The angle 9 (10) is curved laterally from the rack 1. The angle 9 and 10 on the rack 1 are mounted opposite. The cutting edges 11 and 12 at the angles 9 and 10 have directions from the bottom up and back from the cutting edge 13 of the removable element 8. The mounting part 14 of the rack 1 is provided with holes 15 for connecting to the frame of the tillage implement.

The working body of the slot machine works as follows.

The rack 1 with holes 15 on the mounting part 14 is attached to the longitudinal beam of the frame of a commercially available tillage implement, for example, the mounted SchN-2-140 slot machine.

Next, check the technical condition of the detachable bit 2 and the removable element 8. The support wheels of the ShchN-2-140 slotter are set with the help of screw mechanisms in relation to the frame so that the depth of the slit crafts is within 0.40-0.45 m with processing without turnover of the upper soil layer and the preservation of vegetation at a depth of 0.28-0.33 m

When lowering the chaffer frame of the mounted tractor’s hydraulic link, the first of the field surface is the blade blade 2. Chisel 2 carries the removable element 8 into the top soil layer 8 in the groove 7 of the sides 3 and 4 of the rack 1. The cutting edge 13 of the removable element 8 vertically cuts the soil layer in the arable layer and part soil below the plow sole. The cutting edge contributes to the implementation of the frontal edges of the left and right sidewalls 3 and 4. Sidewalls 3 and 4 are sealing side walls of the vertical gap. The cutting edges 11 and 12 of the filming pictures 9 and 10 in the upper soil layer cut the soil layer, forming a gutter on inclined sections directed towards the vertical slit. The gutter facilitates the interception of storm drains and directs precipitation to the bottom of the gap.

The loose soil layer above the gutter contributes to the penetration of precipitation into the gap. With intense snowmelt in the winter and early spring periods, with drip irrigation, as well as rainfall from the inter-strip space (between adjacent slots), moisture flows into the loosened soil zones in the gutters above the slots. In them, it accumulates in the layer with a cross section in the form of a triangle. Excess moisture along the vertical walls of the slit rushes into the loose zone at the bottom of the slit, treated with bit 2. Thus, when irrigated by irrigation, irrigation water is drawn into the underlying horizons, increasing soil moisture reserves both during moisture-charging irrigation and during vegetation during cultivation with / x crops. The shape of the fillet 9 and 10 and the direction of the cutting edges 11 and 12 excludes the overhang of weed vegetation and root residues on them. With a decrease in the depth of the slot, the width of the gutter above the slot differentially decreases. Good conditions for absorbing irrigation water and storm runoff exclude water erosion and displacement of solid (mineral) sediment from the upper, fertile soil layer.

The described working body with charcoal snakes will ensure the interception of any types of precipitation and this will eliminate soil erosion processes.
