Abstract

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to agricultural machines and can be used in agriculture for basic deep tillage, primarily for tilled ones, as well as for various other crops grown in the system of strip farming. Working tool of the tool for strip deep tillage consists of a rack with a shoe welded in its lower part with an overlay bit. Along the post there drilled are holes, through which a pair of cutting wings is attached by a pair of bolts. Outer ends of the underwing wings are made with bending in the form of vertical knives. Profile of bent end along line of knives folding in longitudinal plane forms angle of additional soil crumbling in zone formed by contour of underwing wings. Dimensions of trimming wings are made with account of rack thickness and in compliance with dimensions of tillage.

Description

The invention relates to agricultural machinery and can be used in agriculture for basic deep tillage primarily for row crops, as well as for various other agricultural crops. crops grown in the strip farming system.

A tool is known for minimal tillage with a strip recess, containing a frame with inclined racks mounted on it with an intrasoil bend, each of which has a shoe with an overhead chisel and a slope towards the furrow, which loosens a strip 30 cm wide, and on the opposite side (field trimmings), in the bending zone, a plane-cutting wing with a loosening width of 45 cm is rigidly fixed (http://www.sibagro.com/p_prg.html).

However, this tool affects the entire day surface, which is not necessary when cultivating row crops.

A tool is known for deep strip tillage, including working sections mounted on a frame through a parallelogram mechanism, each of which contains a height-adjustable chisel cultivator with a guide, in front of which there is a central circular knife with flanges and, if necessary, a pair of disk cleaners, and behind circular knives and a roller, moreover, a pair of height-adjustable circular knives are set to the required depth with the plane of deformation from the chisel overlapping. (Patent for the invention No. 2013316464 dated 05/06/2013, prototype).

The technical disadvantage of this tool is the complexity of the design and the high material consumption of the working body.

Also known is a modular working element that can be used for strip loosening, including a rack, a shoe with a patch bit and a pair of cutting wings attached to the rack by a pair of bolts through bushings, one of which is made with an eccentric displacement.

The technical drawback of this modular working body is the technological limitation and low quality of strip tillage.

The technical task is to provide the ability to configure the working body for strip processing with specific parameters of the processed strip by vertical notching of the treated strip and increasing the soil deformation zone of the cutting wings without increasing the width of the processed strip.

The technical result is an increase in the operational and technological parameters of the implement with working bodies for deep strip tillage.

According to the invention, the working body of the implement for deep strip tillage, consisting of a stand, with a shoe welded to the bottom with an overhead bit, holes are drilled along the stand through which a movable pair of cutting wings is fastened with a pair of bolts. The outer ends of the cutting wings are bent in the form of vertical knives, the profile of the bent end along the bending line of which in the longitudinal plane forms the angle of additional crumbling of soil in the zone formed by the outline of the cutting wings. The dimensions of the cutting wings are made taking into account the thickness of the rack and in accordance with the dimensions of the loosening strip.

In FIG. 1 shows the working body of the tool for deep strip tillage, complete view; in FIG. 2 - cutting wing, side view; in FIG. 3 - cutting wing, top view.

The working body of the tillage implement (Fig. 1-3) contains a rack 1, each of which has a shoe 2 with a patch bit 3. Along the rack, holes are drilled through which a movable pair of cutting wings are fastened with a pair of bolts 4. The outer ends of the cutting wings are bent in in the form of vertical knives 5. The profile of the bent end, along the fold line in the longitudinal plane, forms the angle β of additional crumbling of the soil in the zone formed by the outline of the trimming wings. The size of the width S of the cutting wings 4 is made taking into account the thickness M of the rack 1 and in accordance with the size of the loosening strip B.

The working body of the tool for deep strip tillage works as follows.

To increase the infiltration properties of the treated strip, the depth of cultivation of the implement is from 25 to 45 cm. The zone of soil deformation depends on the depth of processing, soil properties and the width of the bit. The combination of these factors affects the critical depth of cultivation that determines the zone of soil deformation on the surface. Given a given parameter of the processing width of 25 cm on the surface, according to the research of V. Trufanova, V. Vetokhin, I. B. Borisenko and other scientists, the width of the bit should not exceed 30 mm. Thus, the chisel working body with a narrow chisel of 30 mm, with a processing depth of 25-45 cm, performs the technological process of snapping with a critical depth of loosening by 10-12 cm, forming a zone of soil deformation on the surface with a width of 20-25 cm. This process increases water absorption capacity of the soil, but the transverse area of cultivation is insufficient for the good development of the root system of row crops. To increase the zone of soil deformation, trimming wings were installed on the rack, the depth of which was set regardless of the depth of slotting by moving the bolted joint along the rack. The implementation of the cutting wings with a bend in the form of vertical knives made it possible to limit the width of the processed strip to the required limits, regardless of the depth of their installation. Performing the profile of the bent wing end, along the fold line in the longitudinal plane, at an angle β, allowed additional crumbling of the soil in the zone formed by the outline of the cutting wings. The size of the cutting width of the cutting wings was performed taking into account the thickness of the rack and in accordance with the size of the loosening strip.

Therefore, such a constructive implementation of the working bodies allows you to increase the operational and technological indicators of tools for deep strip tillage.
