Description

 The invention relates to agricultural machinery, in particular to a section of the working bodies of a tillage implement for processing vapors.

 A well-known working body is a flat-cutting one-sided paw (see Paws and racks of cultivators. General specifications. RD. 23.2.164.87; Edited by V. Polontsa, I. Oil IP Soil preparation, sowing and crop care. A practical guide to technological adjustment of agricultural equipment. - Kiev: Harvest, 1987. - P.53, 54, 46), including a stand, one-sided plane cutting blade, a vertical cheek.

 The disadvantages of the known working body for steam care include the fact that when working from 4 to 6 cm on the field with the presence of crop residues in moist soil, unsatisfactory cutting of weeds occurs due to the lack of sufficient backwater, and if there is a crust on the soil surface cuts and shifts it together with the root system and the aerial part of the weeds, forming the surface of the soil with high combing.

Known working body for processing vapors (see Gasilin V.I. and others. Working body for processing vapors // A.S. an acute angle to the direction of movement and a working plane located at an angle of crumbling; a shield inclined at an angle of 55 ^° to the horizontal plane with a height of more than 4-6 cm and a frontal section width equal to the thickness of the paw.

 The disadvantages of the known working body for the treatment of vapors include the fact that inclined flaps when working at the exit to the day surface significantly change the structural state of the soil: density, hardness, porosity - general, inter-aggregate, of individual aggregates with which moisture and air consumption are directly related, water and air permeability, which determine both effective and potential soil fertility. This disadvantage arises because the shield works in a stream of soil particles without backwater. When working in such conditions of any deformer, including the inclined flap of the working body, the flow of soil particles moves along a curve, and not along a straight line parallel to the working surfaces of both the flap and the paw. This leads to significant friction between the soil particles and to the occurrence of the phenomenon of the removal of moist soil layers to the surface. In addition, this does not allow to obtain a soil surface with minimal ridging.

 A tillage implement is known (see Koptev A.V. et al. Tillage implement // A.S. 2023357 C1, 11/30/1994), including section frames with uprights of flat-cutting legs having blades mounted at an acute angle to the line of movement of the implement.

 The disadvantages of the known sections of the tillage implement should include the fact that their "lead-through" method of attachment to the carrying system of the implement does not ensure uniform movement of the working bodies located on the frame of the sections along the depth of processing, since with increasing soil density the front row of the working bodies begins to raise the frame , and it is located at an angle to the horizon, which leads to a deepening of the working bodies of the second row and subsequent, plant residues hang on the supporting systems of the paws, which also leads to a violation of the stable bility stroke depth paws.

 To eliminate the shortcomings and achieve a technical result, the legs with legs are equipped with inclined shields and have holes for fastening the legs on the axis of the same section with the formation of a block of legs, between each leg legs there are bushings, two of which are equipped with vertical uprights of circular cross section, rigidly fixed to the section frame to ensure the placement of the paw racks in the section in two rows in a checkerboard pattern, while the vertical racks, bushings and working surfaces of the paw racks are coated with fluoroplastic. The frames of the sections are connected to the carrying system of the gun by means of a four-link mechanism, while the lower link of the four-link mechanism is the frame of the section, which is additionally connected to the bracket of the carrying system of the gun through the straps and pressure springs.

 The location of the hole on the rack of a one-sided plane-cutting paws ensures the reliability of the process as a shield and paw. This is achieved by increasing the reliability of the installation of the legs between the cylindrical bushings of the axis and improving the stability of its stroke in width, in the direction of travel and in the depth of processing.

 The double-row arrangement of the working body in a staggered order for processing steam makes it possible to improve the quality of processing along the width of the block, to increase the degree of cutting weeds.

 Placing the cylindrical bushings on the axis ensures alignment, since they are located above the surface of the soil, and, in addition, the effect of soil backing in front of a flat-sided one-sided paw and shield is achieved, which improves the course of the soil processing of the steam field.

 Soil cultivation at the same time as a cylindrical leveler - bushings, an inclined flap, a one-sided flat-cutting paw provides the intensity of the impact of all work planes on the soil, and therefore in one pass of the steam cultivating unit with these working bodies less soil combing is achieved, the overall field evenness is improved, and the root system is completely cut. weed vegetation on a steam field.

 The arrangement of paws in two rows in a checkerboard pattern ensures the operation of the unit without unloading.

 The installation of a block of working bodies on a four-link allows a more stable technological process for processing steam.

 In FIG. 1 shows a working body for processing vapors, side view.

 In FIG. 2 shows a working body, front view.

 In FIG. 3 shows a block of unilateral flat-cutting paws.

 In FIG. 4, the frame of the section of the working bodies located frontally in two rows is drawn.

 In FIG. 5 presents a section of the working bodies, top view.

 In FIG. 6 shows a diagram of the connection of the working bodies with the carrier system of the unit.

 The proposed section of the working bodies of a tillage implement for vapor treatment includes a rack 1, an inclined flap 2, a one-sided flat-cutting leg 3, a square hole 4 located on the rack 1 (Fig. 1, 2). The block of working bodies (figure 3) has legs 3, racks 1, which are located on the axis 5, bushings 6, two of which are equipped with vertical round racks 7. The working surfaces of the racks 1, shield 2, legs 3, bushings 6 and vertical round racks 7 coated with fluoroplastic. The working elements of the block are tightened with a nut 8. The racks 7 are rigidly fixed on the framework of section 9 (Fig. 4) so that the unilateral plane-cutting legs 3 are located frontally in two rows in a checkerboard pattern (Fig. 5). The frame 9 of the section of the working bodies through a four-link mechanism 10 is connected to the carrier system 11 of the unit. The lower link of the four link 10 (Fig.6) is the frame 9 of the section, which is additionally connected to the bracket 12 of the supporting system through the pressure bars 13 and springs 14.

 A feature of the section of the working bodies is that the rack 1 is equipped with an opening 4. This makes it possible to form a block of working bodies with further constructive development of the section, where the working bodies are located frontally in two rows and attach it to the supporting system via a four-link mechanism. In addition, it should be noted that the placement of the uprights 1 on the axis between the bushings provides another working element in the form of a cylindrical equalizer located above the shields 2 at the soil surface.

 The proposed section of the working bodies works as follows. A single-sided flat-cutting paw 3 with a shield 2 and a working surface loosens the soil of the formation, cut together with the root system of weeds. Before this, the fluoroplastic sleeves 6 align the soil in front of the legs 3, therefore, after it leaves the rear edge, the soil evenly lays on the bottom of the furrow with the formation of a flat surface with minimal combing.

 The effectiveness of soil cultivation by the proposed section with working bodies is as follows: the number of useful fractions of the soil up to 20 cm in size is at least 80%, the complete destruction of weeds. The minimum movement and removal of moist soil layers to the day surface is achieved not only by combining the work of the originally arranged elements, but also by joining the frame of the sections of the working bodies by means of a four-link mechanism, which ensures plane-parallel movement of the paws in the soil, stabilizing a more uniform course of their first and second rows.

 The use of the proposed section of the working body of the tillage implement improves the quality of the unit with the proposed connection with the supporting system of the cultivator.

 The use of a section of the working bodies of a tillage implement for treating steam does not adversely affect the environment.
