Description

The invention relates to agriculture, in particular to irrigation technology.

The purpose of the invention is to improve the quality of irrigation of agricultural crops by adjusting the angle of the rain plume with minimal pressure losses.

Fig. 1 schematically shows a section of a multi-support sprinkler in the position of sprinkling nozzles at a level of 0.5 - 1.0 m from the soil, front view; 2 - the same, but in the position of the sprinkling nozzles at a height of 0.5 - 1.0 m from the surface of plants; on fig.Z - car, cross section; Fig. 4 is a diagram of adjusting the position of the nozzle through the scenes; Fig. 5 is a diagram of the sprinkling of the circular action nozzles; Fig. 6 shows a sprinkling pattern from above

The multi-support sprinkler includes (figs. 1 and 2) the chassis in the form of self-propelled carriages 1, carrying a truss consisting of a stitch 2 and a pressure pipe 3, along which are located

the specified pitch Rtrubki-nipple 4, to which the sprinkling device 5 is connected. The sprinkler device separately (fig. 3 and 4) is made in the form of a hose water outlet 6. one end of which is connected to the connecting pipe 4, the second, to the nozzle 7, the hose passes inside the hollow lever 8 with the part of the hose protruding from it with the nozzle 7. One end of the lever 8 is pivotally connected at the clearance height of the machine bkl with the clamp 2 of the truss and is fixed by a clamping device, for example a collar 9. The end that is released from the lever tube 8 hose b with nozzle 7 ime a metal ring to which the lever 8 is hingedly connected by a rocker mechanism 10, the groove of which is connected to the end of the lever 8, having a lock 11 of the sprinkling head 7, allowing fixing the nozzle 7, for example, in the lower position D1 at a height hi 0.5 - 1, 0 m, intermediate positions Дп and Дш at a height of 0.5 - 1.0 m from the surface of the tops of the plants and the vertical position D | у- above the clearance of the RLS position of the tie-down 2 farm machine.

If the wind speeds in the region are low - up to 1.5 - 2.0 m / s, the angle of elevation of the deflector part of the nozzle of the rain plume can be increased by means of the scenes 10.

The collar 9 (figure 4) tightly covers the tie 2 due to the compression of its cheeks with a bolt. it

prevents the lever tube 8 from spontaneously turning around the clamp 2 from the influence of its mass (except for the nozzle position below) and the reaction of the water jet ejected under pressure from the nozzle deflector.

The machine works as follows. Before irrigation (Fig. 1) of the seedlings of agricultural crops, the sprinkling devices 5 are pre-fixed on the stitches 2 with a given pitch f and the minimum height of the nozzles 7 relative to the irrigated soil surface

0.5-1.0 m. Water from the pressure pipe 3 through the fitting 4 through the flexible hose b during operation is supplied to the nozzle deflector 7 and sprayed over the irrigated surface. When reaching the height of the stem of plants in the process of vegetative irrigation, for example. 1 m (Fig. 2) loosen the bolts of the clamps 9 (Fig. 4), turn the lever 8 around the bolt 2 to the required height of the nozzle 7 The clamp 9 clamp the bolt and fix the position. By means of the backstage 10, the nozzle is placed, for example, in the position of Ds or Ds (fig. 3 and 4). When reaching the heights of high stem culture, height 2.2. 2.4 m machine close to ground clearance (for example, at Kuban-GG 2.7 m from the ground), the machine is taken out of the floor and in this order set nozzles 7 to the D position |

for final watering.

Claims (1)

Invention Formula A multi-girder sprinkler machine containing a truss with a casing, an irrigation pipeline, on both sides of which along the front of the machine there are hose water outlets with deflector nozzles and devices for lifting and lowering hose outlets. characterized by the fact that. in order to improve the quality of irrigation of agricultural crops by adjusting the angle of the rain plume at minimum head losses, deflector nozzles are equipped with rocker mechanisms for changing the position of nozzles, and devices for raising and lowering hose outlets are arranged in a checkerboard pattern along the front of the machine and made in the form of hollow levers hinged to the trusses of the truss with hollow arms inside and out of them. water outlets with This hollow levers in the hinge. and from the other end, the retainers are equipped with retainers for the position of the deflector nozzle mechanisms. 1 ЖЖЖЖ ± Ј1 5h vN v HHHHHh 1   V4 V VC4 VV V4 Vv4 4 4 S FIG. 2 s. x Ghh sN / /////// 1% H ° FIG. four V corner 5 f err,} {((" 1 (xGT (U (/ f, (Yyyy LH hyyyy f / j  V, / rf (ul BP Dbimenter machine /. - G & W one //.  / 1. 1GG I , 4- O H v Hh w xv - h - g k- (g:  -g,: ъ (, "(S.
