    The invention relates to agriculture and can be used for irrigation with self-propelled positional irrigation machines (PM) powered by a closed pressure irrigation network.
    The aim of the invention is to increase the reliability of operation.
    Fig. 1 is a side view of the intake (perpendicular to the line of hydrants); FIG. 2 is the same front view (along the line of hydrants); FIG. 3 is a section A-A in FIG. 2; Fig. 4 - section BB in FIG. 2; Fig. 5 shows a section B-B in Fig. 1 (two extreme positions of the connecting nozzle of the intake device); FIG. 6 is a section through the carriage GGD in FIG. 5 (knot); Fig, 7 - section. DD in FIG. 4 (the structure of the seals of the telescopic sections of the connecting nipple); Fig. 8 is a hydraulic circuit of the control unit.
    A water intake device (WU) for supplying water to the irrigation machine (PM) from hydrants 1 of the pressure pipe 2 is installed on the frame 3 PM, moving positionally RO to field 4 on wheels 5, n equipped with a supply pipe 6 in the form of a bend with a branch pipe in which non-return valve (not shown). Supply supply line 6 is connected to the flexible water supply hose 7 in the PM to provide vertical movements of the supply pipe 6, the Frame is installed on the pipes 8 rigidly connected to the PM chassis and provided with two hollow vertical beams 9 mounted on the transverse beams
    10 and acting as guides in which the rods 11 of the suspension 12 of the wheels 5 are coaxially mounted. To ensure the rotation of the wheels 5 of the suspension 12, a 13 is connected to each other, driven by a hydraulic cylinder 14 of rotation of the PM wheels,
    Two vertical guides 15 of the water intake device (WU) are rigidly mounted with brackets 16 on transverse beams 10, and rigid pipes 17 are movably installed inside them, at the lower ends of which are articulated clamps 18 in the form of brackets for fixing the CU relative to the flange 19 of the hydrant body 1 , The upper ends of rigid pipes 17 St for 255036 - 2
    between each other, a transverse thrust of 20 DNFs to ensure synchronous reciprocating movement of the pipes 17 when clamps 18 of the flange are gripped by means of a lever gear 21 connecting the clamps to the lower ends of the vertical guides 15, and the subsequent hydraulic connection of WU to the hydrant 1, О For compaction in the process of attachment and water intake, a flexible stocking membrane 22 is used, installed between the outer (top according to the drawings) telescopic section 23 of the connecting nozzle, mounted on the brackets of the carriage 24, and an internal telescopic section 25 connected by springs 26. The inner telescopic section 25 has 20 an inner annular protrusion 27 with a cone at the bottom for mating with the conical surface of the upper part of the hydrant 1,
    The carriage is installed with a vertical reciprocating motion along the guides 15 on the outer side with the help of the lower rollers 28 and on the inner side with the vertical rollers 30 29, the carriage is rigidly connected to the inlet pipe 6 (knee), on the lower the flange of which is installed the upper section 23 of the connecting pipe. The supply pipe 6 (knee) is kinematically connected to the hydraulic cylinder 30 of the vertical drive of the connecting pipe as follows: the housing of the hydraulic cylinder 30 is pivotally connected to the transverse 40 bar 20, and the rod 31 through the knee
    supply pipe 6 - with an external telescopic section 23 of the connecting pipe. The inner telescopic section 25 is provided with a connecting cone 32 and an o-ring seal 33, ensuring its tight connection
    35
    with hydrant 1,
    A central rod 34 passes through both telescopic sections of the connecting pipe and is attached to the upper (outer) section 23 and is thus connected with the rod 31 of the hydraulic cylinder 30. The upper telescopic section is below. an expanded area for forming a cavity 35 in which the stocking membrane 22 is installed, coagulating
    3
    and sweeping with the vertical movement of the telescopic sections one relative to another without the rubbing of the slide.
    The central rod in the process of attaching the telescopic pipe to the hydrant 1 interacts with the axial rod 36 of valve 37 of hydrant 1, while the valve plate 38 moves away from the saddle, overcoming the pressure of the pressurized water and spring 39 and opening the passage of the Veda to the connecting pipe.
    The electro-hydraulic control system of the hydraulic cylinder 30 includes two reversible lines 40 and 41 supplying and draining the working fluid (oil) and the hydraulic distributor 42, one outlet of which is directly connected to one of the hydraulic cylinder (HZ) cavities 30, and the other to the second HZ cavity through two successively connected adjustable throttles 43 and 44, in parallel to which two check valves 45 and 46 are oppositely connected.
    On the suspension 12 of wheels 5, rods 47 are mounted with stop actuators 48 for a precise chassis at the hydrant mounted on rack 49
    To control the vertical movement of the connecting pipe on the connecting pipe 6 (knee), a bar 50 with sensors of the extreme positions of the connecting pipe in the form of starters 51 and 52 with limit switches 53 and 54 is installed. The control system also has an intermediate sensor 55 from the connecting cone to the hydrant mounted on the bar 56 with the possibility of adjusting its position with the help of bolts.
    Water intake irrigation machine works as follows.
    When the PM moves along the pressure pipeline 2, the starter 48 mounted on the rod 47, when interacting with the vertical pin fixed in the soil 4 near the hydrant, sends a signal to stop the PM so that



    This means that the vertical axes of the hydrant and the attachment pipe coincide. The direction of movement of the PM is controlled by the operator by means of a hydraulic cylinder 14 by means of a pull 13.

    ticking reciprocating movement under the action of HZ 30 begins to descend. In this case, a check valve installed in line 6 (not shown) does not allow water to flow out of IIM. The supply pipe 6, connected to the upper (outer) part of the telescopic pipe and mounted on the carriage, moves along the guides 15 downwards. At the same time, at the beginning of the movement, both sections of the telescopic nozzle move first synchronously, since they are connected to the springs: 26 squeezing, right up until the upper conical part of the hydrant 1 is mounted on the inner annular flange 27. Sealing the joint is provided with an annular seal 33. serves as a connecting body 32 in the lower part of the internal telescopic pipe.
    Further movement of the piston rod 31 of the HZ 30 leads, on the one hand, to the vertical movement of the rigid pipes 17 in the guides 15 and, through the lever gear 21, to the gripping of the flange 19 of the hydrant body with the clamps 18, and the other side to further lowering the upper part 23 of the telescopic elbow and together with it, the central rod 34. The latter movement occurs more slowly, since the intermediate sensor 55 is triggered, reducing the speed of movement of the rod 31 Hz 30, to eliminate hydraulic shocks when the central rod interacts with the valve stem ana hydrant. The stocking membrane 22 seals the inner and outer sections of the telescopic nozzle. After the end of the extension of the HZ 30, when the extreme position is reached, at which the hydrant 1 is gripped by the clips 18, and the hydrant valve is fully opened, the extreme position sensor disconnects the hydraulic system of the HZ 30 during the irrigation period from this hydrant.

    The end position switches, in the form of starters 51 and 52, are used to control the operation of the water intake device by means of the distributor 42 as follows. The hydraulic system has lines 40 and 41 from the chassis hydraulic system for reversing the oil flow bath, i.e. for reversing the stroke of the HZ 30 stock with the insertion and removal of the stem (removal - oil flow clockwise in Fig. 8, introduction - counterclockwise). With the position of the distributor 42 shown in Fig. 8, the oil through the distributor is sent to HZ 30 directly to remove the HZ stock. When the HZ rod is extended and the switch is actuated, the solenoid actuates the switching valve 42 and directs the oil through the valves 45 and 46, while the valve 46 actuates the throttle 44 and reduces the flow in the HZ 30, significantly reducing the extension speed of the rod to eliminate hydraulic shock.
    After the termination of irrigation from this hydrant, WU is disconnected from the hydrant.
    in the reverse order, in which case, the slow retraction of the HZ 30 rod and the slow closing of the hydrant valve 1, which are determined by the actuation of the valve 45, which activates the throttle 43, occurs first, and after the hydrant valve closes (when the sensor 55 is triggered), the distributor switches 42 and quick disconnection of the control unit.
    The advantages of the proposed WU are the simplicity of the design (only one drive 15 hydraulic cylinder is used) and reliability in working on polluted water due to the use of the stocking membrane between the telescopic sections of the connecting pipe -20 ka. ,
