Information confirming the possibility of implementing the invention are as follows.

The self-mounted two-console truss for sprinkling machines is made in the form of a three-belt spatial design with one upper and two lower belts. The farm contains a central panel 1, left and right consoles 2 and 3 (see Fig.1-22).

The central panel 1 (see Fig. 15, 16 and 17) is made in the form of a regular pyramid with a square base of water pipes 4, 5 and 6, mutually connected at right angles to the spacers 7 and 8 between the pipes 4, 5 and 5, 6. At the end of pipes 4 and 6, flanges 9 are made, and pipe 5 has two flanges 10. The pipe 5 from the bottom has bends 11 with flanges 12 for connecting flexible hoses to divide the water flow from the pump of the two-console sprinkler unit, driven by the engine of the aggregated tractor. The square base of the central panel 1 is supplemented by water pipes 13, 14 and 15, mutually connected at right angles to the struts 16 and 17 between the pipes 13, 14 and 14, 15.

At the ends of the pipes 13 and 15 there are flanges 16 connected through gaskets to the flanges 9 of the pipes 4 and 6. The ends of the water supply pipe 14 are provided with flanges 17. The segments 18 of the front water supply pipe are connected to the flanges 17 of the front water supply pipe 14 on the consoles 2 and 3 of the lower belt. To the flanges 10 of the rear water supply pipe 5, segments 19 of the rear water supply pipe are connected. Pipelines 14 and 5 on the base of the pyramid have gussets 20 (Fig. 15-17), to which four pendants 21 are connected, oriented along the edges of the regular pyramid to its apex bounded by the central gusset 22. On the right side of the pyramid, along the apofem between the central gusset 22 and pipes 6 and 14 contain a stand 23. The left console 2 and the right console 3 of the truss are connected to the central panel 1 by means of one upper and two lower belts. The assembly, installation, suitability and transportability of the farm is ensured by the fact that the central panel 1 is interfaced by means of fasteners with the left console 2 and the right console 3. Each console 2 (3) consists of one end panel 24 and thirteen intermediate panels 25, indicated on the drawings by Roman numerals XIII , XII, XI, X, IX, VIII, VII, VI, V, IV, III, II and I.

Each of the thirteen intermediate panels 25 is made in the form of two inclined racks 26 and 27, connected by the upper ends with the upper truss belt, one horizontal strut 28 between (see Fig. 15 and 43) segments 18 and 19 of the front water supply and rear water supply pipelines left and right consoles 2 and 3, the front segment 18 and the rear segment 19, respectively, of the front and rear water-conducting pipeline belts, one upper belt 29, two inclined braces 30 and 31, two - front and rear - horizontal stretch marks 32 and 33 and two otkostruynyh nozzles 34 on the segments 18 and 19 (see. Figure 15, 16, 17, 18, 19, 20, 21, 22, 23, 26, 27, 32, 33, 34, 35, 41, 43).

Segments 18 and 19 of the front and rear water supply pipelines of the lower zone are equipped with pairs of opposed fittings 35 (see FIG. 43), to which lower horizontal struts 28 are fixed by means of U-shaped forks 36 and fasteners 37. Spacers 28 hold segments 18 and 19 in each intermediate panel 25 with mutual removal of l ₂ (see Fig.7 and 14).

The lower ends of the inclined front 26 and rear 27 racks forks 38 are connected to the gussets 39 by means of fastening 40 in each of the segments 18 and 19 of the front and rear water pipelines (see Fig. 43). The upper ends of the inclined racks 26 and 27 with forks 41 and fastening means 42 are connected by λ-shaped fittings 43 of the upper belt 29 (see Fig. 27 and 32). Each upper belt 29 has a U-shaped bracket 44 at one end and a λ-shaped fittings 43 at the other end. The upper zones 29 are mutually and sequentially connected by axes 45 with a diameter of 32 and a length of 40 mm (see Figs. 27, 32 and 34). The distance between the centers of the holes of the forks 38 and 41 at the ends of the uprights 26, 27 is made equal and equal to l ₁ (see Fig. 7 and 14).

The upper belt 29 in double-console sprinkler farms, mounted by means of a chimney 22 of the central panel 1 on the frame of the sprinkler machine and the chassis of an aggregated tractor in the XIII panel, has a length of 5150 centered on the axes in the models of sprinklers DDA-100 VX and DDA-100 V (see Fig. .1 and 2 and Figs. 8 and 9). The length of the upper belt 29 in the intermediate panels 25 (XII to II) is 4000 mm (Figs. 1, 2, 3, 4 and 8, 9, 10, 11).

The inclined braces 30-31 (see Figs. 1-6, 8-13) have a fork on the upper and lower cones, through which they connect the pipe cuts on the segments 18 and 19 of the pipelines of the lower belt and the λ-shaped cut 43 of the belt 29 (see Fig. 41).

Horizontal stretch marks 32 and 33 exclude the mutual shift of segments 18 and 19 in the intermediate panels XIII-VI. The same length of the stretch marks 32 and 33 in the panels XIII-VI provides mounting brace 46 (Fig.23). It is equipped with a plug 47 on the threaded rod 48 and an S-shaped bracket 49 and a plug 50 on the rod 51. Forks 47, 50 and the axles 52, 53, the mounting bracket 46 is mounted on the fittings 54 and 55 of the segments 18 and 19 of the lower water supply pipelines.

The front 32 and rear 33 extensions (see Fig. 26, 33, 35) have an identical design. Each of the stretch marks is equipped with forks 56 at the ends of the rod 57. The forks 56 have openings for installing axes 58 of kinematic connection with the fittings 54 and 55 on segments 18 and 19.

Segments 19 of the rear water supply pipe and segments 18 of the front water supply pipe are mutually connected by flanges 10 and 17 through gaskets made of rubberized material. Flanges 10 (17) and gaskets of mating segments 18 (19) are pulled together by means of fastening (see Figs. 1, 2, 8, 9, 16, 17, 18, 19, 20, 21, and 43).

The angle of inclination of the pipelines of the lower zone to the horizon is 2 ° 17 '(see figures 1 and 8).

Along the length of the pipelines of the lower zone, they approach each other, because to the axis of symmetry of the truss they are installed at an angle of 1 ° 19 '(see figure 3 and 10).

On each intermediate panel 25 (XIII-V), two short-jet nozzles 34 are mounted (see Figs. 16-22, 42, 49-53). Each of the nozzles 34 has a plastic housing 59, a nozzle 60, a curved blade 61, a fitting 62 for screwing into the nipple 63 of the segment 18 (19). The body 59 of the nozzle 34 has a hexagon for screwing the nozzle 62 into the threaded part of the nipple 63. The position of the body 59 of the nozzle 34 in the nipple 63 is fixed with a shaped nut 64. This allows you to quickly configure the nozzle 34 taking into account the speed and direction of the surface wind. In the nipple 63, a replaceable calibration washer 65 is mounted (see FIG. 53). Table 1 shows the parameters and the number of washers 65 in the nipples 63 in the panels I-XIII, depending on the capacity of the installed pump (l / s) of the sprinkler.

The end panel 24 (see FIGS. 20-22, 25, 31) is made in the form of a cable-stayed part of the sprinkler farm. The cable stay of the truss in the left 2 and right 3 consoles of the truss is connected to the VI intermediate panel 25 of the truss by means of a triangular element in the form of a horizontal strut 66 and the inclined racks 67 and 68. The conjugate ends of the inclined racks 67 and 68 are oriented down and placed below the horizontal strut 66. The ends segments 18 and 19 of the front and rear water pipes with the pipeline guyed part of the farm are paired with a V-shaped water element 69 (see Fig.20 and 21). The intermediate panel V is formed by inclined racks 27 and 26 and a horizontal strut 28 placed in the transverse vertical plane. The coupled ends of the inclined racks 26, 27 are placed above the horizontal strut 28 and connected to a special frame 43 (see Fig. 20, 21, 27, 28) equipped with a Δ-shaped plate 70 and an arm 71 with an axis 72. The Δ-shaped plate 70 special shaped 43 fingers 73 is connected with braces 74 and 75 (see Fig.20, 21, 27 and 28). The bracket 71 is connected via a finger 72 to a brace 76 connecting the V-shaped water conducting element 69.

Inclined racks 67, 68 through a horizontal strut 66 of the IV panel are coupled with gussets 54 and 55 at the ends of segments 18 and 19, as well as the front and rear inclined stretch marks 77 and 78 and the front and rear braces 74 and 75 (Figs. 20, 21 and 29 ) The interface node of the V-shaped water supply element 69 with the water supply pipe 79 of the cable stay of the truss is additionally connected by a brace 76 with a bracket 71 in the gusset 43 at the top of the inclined racks 27 and 26 (Fig. 27).

The segments 80 of the water supply pipe 79 of the cable stay of the truss are equipped with flanges 81, which are interconnected via rubberized gaskets 82 and fastening means 83 (Fig. 48). Segments 80 in panels IV-I have nipples 63 on which short-jet nozzles 94 are placed (FIGS. 20, 21 and 42).

The end panel 24 is equipped with a nipple 63 for installing a short-jet nozzle 34, a drain valve 84 and a long-range nozzle 85 (Figs. 20-22, 42, 47, 52).

The long-range nozzle 85 is located in the nipple 86, welded in the flange 87 at the end of the water supply pipe 79 of the cable stay of the truss (see Fig. 20, 21, 47, 44, 45). The long-range nozzle 85 of the welded construction has a nozzle 88 in the housing, a stiffening rib 89 and a blade 90 installed at an angle to the axis of symmetry of the nozzle 88. The blade 90 is given the shape of a circle. The body of the long-range nozzle 85 has a threaded portion for screwing into the nipple 86 on the flange 87 of the pipe 79 of the end panel 24.

The pipeline 79 of the cable-stayed part of the truss is suspended from the triangular element IV of the intermediate panel 24 by means of four pairs of cable ties 91, 92, 93 and 94 (Fig. 15, 20, 21, 22, 24, 30). The lower ends of the cable extensions 91 - 94 have forks 95 (see Fig. 30), through which they are connected through axes 96 to the gussets 97 on the surface of the segment 80 of the water supply pipe 79. The upper Z-shaped ends 98 of the cable extensions 91-94 are placed in the technological holes 99 of the mounting plate 100 (see FIG. 24). This provides the required slopes of the cable extensions 91-94 to the horizon. The front and rear mounting plates 100 are connected to the mating ends of the upper horizontal strut 66 and the upper cones of the inclined racks 67 and 68 (see FIGS. 20, 21, 22, 29, 24, 25) by means of the front and rear L-shaped gussets 101 and 102 A pair of L-shaped fittings 101 and 102 are made in mirror image (see Fig. 36, 37, 38, 39 and 40).

The front and rear mounting plates 100 with a pair of L-shaped gussets 101 and 102 are connected by fastening means 103 placed in the holes of the plates 100 and gussets 101 and 102 (see FIGS. 46 and 29). L-shaped fittings 101 and 102 with the upper horizontal strut 66 and with the upper ends of the inclined struts 67 and 68 are connected by axles 104 (see Fig.29). The lower ends of the inclined racks 67 and 68 are connected with segments 80 of the water supply pipe 79 of the cable-stayed part of the farm by means of fittings 105, 106 and fastening means 107 (Fig. 31).

The technical result in terms of reducing material consumption and maintaining technical and operational reliability is achieved by the fact that the upper ends of the cable extensions 91, 92, 93 and 94 are equipped with Z-shaped brackets 98 mounted in groups in the technological holes 99 of the mounting plates 100 (Fig. 24). The horizontal strut 66 with inclined racks 67 and 68 is paired with a pair of L-shaped brackets 101 and 102 made in mirror image (Fig.25, 29, 36, 37, 38, 39 and 40). The angle of the solution λ between the shelves 108 and 109 of the L-shaped brackets 101 and 102 is made in the range of 45 ... 60 ° ± 2 ° (Fig. 38) and ensures the mounting suitability of the upper horizontal strut 66 with inclined racks 67 and 68.

The setting angle β of the shelves 101 and 102 in the brackets 101 and 102 provides the desired position of the mounting plates 100 to accommodate the cable ties 91-94. The mounting plates 100 for cable extensions 91-94 are fixed by means of fastening 103 (Fig. 46) on the L-shaped brackets 101 and 102.

The intermediate panel 25 (VI) of the truss part is paired with the panel IV of the cable stay part of the truss with a special λ-shaped gusset 43 (see FIGS. 20, 21, 27 and 28) equipped with a Δ-shaped plate 70 and an arm 71. The plate 70 and the arm 71 the fittings 43 are connected by slopes 74, 75 and 76 inclined to the horizon with L-shaped brackets 101 and 102 of the spacer 66 and a V-shaped water supply element 69 for hydraulic communication with the water supply pipe of the cable stay of the farm. The remote ends of the inclined braces 77 and 78 and the braces 74 and 75 are paired with L-shaped brackets 101 and 102 on the horizontal strut 66 of the panel V of the cable stay of the truss (Figs. 21 and 29).

The cable extensions 91 and 94 provide a rise in the long-range sprinkler apparatus 85 by a value of h _o (see FIG. 22) in comparison with the VI panel.

The numerical parameters of the truss shown in Figs. 1-14 indicate the interchangeability of XIII-I panels in the manufactured DDA-100 V models manufactured by the DDA-100 BX, DDA-100 MA and discontinued DDA-100 models and the reliability of the truss connection parts with a central panel 1 in the form of a pyramid.

Self-mounted two-console farm for sprinkler machines operates as follows.

From the pumping unit of the sprinkler mounted on the tractor’s chassis, through flexible hoses, water enters the flanges of 12 branches 11 of pipe 5 at the base of the pyramid of the central panel 1. Through pipes 5, 4, 6 and 15, 14, 13 at the base of the pyramid of the central panel 1 water under pressure is redistributed to the front water supply pipe and the rear water supply pipe of the lower zones on the left 2 and right 3 consoles. As the water moves in the segments 18 and 19 of the pipelines, part of it through the short-jet nozzles 34 is distributed in the form of raindrops. Most of the water from the pipelines through nozzles 34 is distributed in the form of artificial rain in the intermediate panels 25 (XIII-V) of the trusses of the consoles 2 and 3. The remainder of the water from the pipelines through the V-shaped water supply element 69 is sent to the pipeline 79, composed of segments 80 s nipples 63. Short-jet nozzles 34 on segments 80 irrigate a significant part of the area occupied by the cable-stayed part of the farm. The irrigation working zone is increased by long-range sprinkler devices 85 on the end panels 24. The water stream flowing from the nozzle 88 of the long-range device 85 is broken on the blade 90 into agrotechnically acceptable drops for irrigation of crops without mechanical damage.

The quality of the rain at the end sections of the farm is provided by V-shaped water supply elements 69 connecting the cable lines 79 of the cable-stayed part to the front and rear pipes from the segments 18 and 19 of the truss.
