FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, to tillage tools for primary tillage,

The purpose of the invention is to reduce traction resistance.

FIG. 1 shows a tillage tool for the main soil processing, a general view of FIG. 2, a mutual arrangement of a soil cultivator and a plow body; Fig. 3 is a diagram of the soil resistance forces acting on the plummer body and the ploughshare of the subsoiler J on. FIG. 4, a soil-cultivating tool, general VIEW} in FIG. 5, a subsoiler, a general view,

The tillage implement contains a frame, 1, a support wheel 2, a plow body 3, reinforced on the frame by means of a stand A, Behind the plow body and below the blade of its plowshare the submersible plower 5 is located, the blade of which is at an angle to the direction of movement opposite to the installation angle blade plowshares plow body. The ploughshare 5 is installed on the post 6 pct pc

The bin of the stroke of the plow body is installed with the help of height-adjustable support wheels. Seeding organic and mineral fertilizers in the upper part of the soil contributes to the saturation of this part of the arable layer with nutrients and fertilizer and the treated soil layer.

The ploughshare 5 soil cultivator cuts, loosens and crumbles the lower arable layer of soil with a thickness of 8-14 cm without turning the reservoir, reducing traction resistance of the tool due to the absence of lifting operations, turning and throwing this part of the arable layer towards the soil.

The depth of the plowshare 5 is set by continuously changing the pillar 6 relative to the frame. At the end of the installation of the required depth of the coulter 5 relative to the blade of the plow body blade rack 6 is fixed in this position

To ensure the processing of various soils with minimal energy expenditure, the design of fastening the plowshare 5 to the stand 6 provides for the possibility of changing the cutting angle in horizontal

five

by means of a means of a horizontal plane, this allows

guilting the angle of its blade to the direction of motion. The adjustment tool is made in the form of a vertical axis 7 and a clamp 8 placed in the arcuate paeu, filled with 5 in the share of 5,

The blade of the plowshare 5 of the subsoiler is located in the horizontal plane between the trace of the center of mass located in it

9 and 10. Line 9 is a 40 ™ projection that simultaneously passes on the horizontal plane, starting through the trailer point of the combined generatrix of the dump surface of the plow body 3, and line 10, the projection is perpendicular to the direction of movement recovered from the outermost point of the upper part of the spindle the surface of the plow body 3,

The implement is attached to the tractor using a hitch system and works in the following way.

When buried in the soil, the plume body 3 cuts, lifts, wraps and throws aside the top layer of soil with a thickness of 8-16 cm, embeds organic and mineral fertilizers on the surface into the soil, where the roots of plants actively absorb the necessary nutrients. Glu50 required

and the center of resistance

Such a passage of the line of action of the force of gi allows one to eliminate the appearance of a deflecting moment in the gun at the expense of the absence of eccentricity of the force of gi and, therefore, to maintain the stability of the movement of the gun across its width

 The arrangement of the blade of the plowshare 5 between lines 9 and 10 reduces soil loading on the dump surface of the plow body 3 by eliminating extrusion of the plowshare 5 onto the surface of the lower soil layers, and also helps to reduce the mass of the soil on the surface of the subsequent plow casing due to the exclusion of discarding

to obtain, under specific conditions, an optimal ratio of lateral components of the forces R, j and R (Fig 3), at which the friction force of the field board of the plow body against the furrow wall is minimal, to form the center of resistance of the tillage tool in the horizontal plane in such a way that the line mass center trace

and the center of resistance

Such a passage of the line of action of the force of gi allows one to eliminate the appearance of a deflecting moment in the gun at the expense of the absence of eccentricity of the force of gi and, therefore, to maintain the stability of the movement of the gun across its width

 The arrangement of the blade of the plowshare 5 between the lines 9 and 10 reduces soil loading on the dump surface of the plow body 3 by eliminating extrusion of the plowshare 5 to the surface of the plowshare and also reduces the mass of the soil on the surface of the subsequent plow body by eliminating discarding

soil from the surface of the plowshare 5 in the direction of the subsequent plow body guns.

The interposition of the plowshare 5 and the plow body 3 at some distance from each other in the direction of motion ensures the scaling of the soil of the fcde layer (Fig. 4) during its movement without contact with the surfaces of the plow body 3, which reduces the energy costs of processing the entire layer soil abde this tool.

Thus, a reduction in traction resistance is achieved due to the layer-by-layer processing of the soil layer, due to a significant reduction of friction forces on the field boards of the plow bodies, due to the stabilization of the tool stroke across the working width and by increasing the operating speed of the unit.
