    The invention relates to agriculture, in particular to devices for spraying a liquid intended for the treatment of cultivated plants or soils.
    The purpose of the invention is to reduce the flow rate of the fluid and higher operating reliability.
    FIG. Figure 1 shows a rotating sprayer, front view; in Fig.2 installation in the first embodiment, the cross section of the axial plane; on fig.Z - installation according to the second variant, front view; in fig. 4 the same, section in the axial plane; in fig. 5 — a guide to a conventional setup for spraying a liquid; in fig. 6 - system of peristaltic pumps, sectioned with 1e axial plane ;; in FIG. A-A in FIG. 6
    The installation comprises (FIGS. 1 and 2) an electric motor 1, which is housed in the casing 2 and which is powered by a cable 3 passing through the casing 2. Means (not shown) are provided in the device for precise adjustment of the rotational speed of the electric motor 1. At the ends of the shaft 4 of the engine 1, which extends from the casing 2, there is a sleeve 5, for example, of molded synthetic material, which is rigidly connected to the disk 6, the perpendicular end of the shaft: 1a 4, or radial elements, each of which contains its side Not opposite to the casing 2, the recess in which the permanent magnet 7 is placed. The rotating nozzle the ripper 8 has, in this embodiment, the shape of a shallow Cup, the bottom of which is rigidly connected to the first cylindrical element 9, connected to the top with the corresponding end Couplings 5j, as well as the second cylindrical element 10, whose vouto diameter is slightly larger than the internal diameter of the cylindrical surface into which the permanent magnets 7 are inscribed, the metal ring 11 is placed inside the two cylindrical elements 9 and 10 so that its left surface (2) adjacent to the permanent magnets 7. This ring is preferably made of soft iron. The device provides an interface for rotating

    pypitel 8 with the end of the shaft 4 of the engine in conditions that allow you to very quickly remove and reinstall the sprayer 8,
    5 Opposite to the central part 12 of the surface of the rotating atomizer 8, which is opposite the engine 2, a cylindrical nozzle 13 comes out. A pump (not shown, for example, with a constant
    fO volumetric flow rate) takes away the liquid for spraying in the tank and is fed to the nozzle 13 through the line 14 of the feed system.
    The casing 2, in which the motor 1 is enclosed, is extended on the side of the atomizer 8 by a flange in the form of a truncated cone 15, the circumference of which is rigidly connected to the fluid collector 16, which has the shape of a toroidal groove almost closed transverse

    sections, with the exception of a narrow annular slot 17 at the level of plane 18 (dotted dashed line in FIG. 2), which is perpendicular to the axis of the rotator and which passes along its outer edge 19. Collection 16 has the shape of a sector of a ring with an angle equal to (360 &), so as to move away from the outer edge 19 of the sprayer 8 in the plane
    18 is only at angle 9; the lowest part 20 of collection 16 is open above the chute 21, the exit in vdm, in turn, to the recuperation receiver 22.
    Installation in the first embodiment works as follows.
    The liquid jet coming out of the nozzle 13, splashing against the central part 12 of the spray gun 8, the centrifugal force drops droplets of the sprayed fluid to the periphery of the spray gun 8, which drops the droplets in the plane 18. All droplets ejected at the level of the ring collector 16 penetrate into the mountainous trough through the slit 17, then by gravity move to the lowest part 20, from there the liquid collected by the collector 16 flows into the receiver 22 along the chute 21. For the treatment, only droplets of the splashed liquid are used thrown by the outer edge
    19 rotating atomizer 8 at the level of a fixed sector with an angle
    55 g released by the annular collector 16. The liquid collected in the receiver 22 is directed to a tank (not shown) using a small
    40

    a centrifugal pump 23, which is driven by an electric motor 24 and which injects fluid into the return pipe 25, at the inlet of which a check valve 26 is placed; when the centrifugal pump 23 stops, this check valve rte allows the fluid contained in the return pipe 25 to enter the receiver 22
    In the second variant (Fig. 3 and 4), the collection 16 or at least a part of it opposite the flange in the shape of a truncated cone 15i contains two elements in the form of a sector of rings 2 and 28, which are installed with the possibility of moving, the concentrating rotating atomizer 8, one relative to the other, as well as to the relatively fixed part 29 of the collector 16, which is rigidly connected with a flange made in the shape of a truncated cone 16. Just as in the first embodiment (fig. 1 and 2), the lowest part 20 of the annular collector 16 , namely its element 27, from hiding over the chute 21, which goes into the receiver 22, which serves to recover the liquid. FIG. 3 shows the positions of two moving elements 27 1 and 28 of the ring collector 16, which correspond to its maximum opening, i.e. the ejection angle of the fluid close to the angle 0 (Fig. 1). In FIG. The 3 dotted and dashed lines indicate the positions of the moving elements 27 and 28 of the ring collector 16, which correspond to the smallest opening of the collection, i.e. the spray angle 1 9 is smaller than the maximum angle 9. This allows you to adjust the spray angle Q between the maximum and minimum values, which can be even smaller than 9 (FIG. 3), namely as small as 10 or 15. Such low values of the spray angle b allow for a spray volume of significantly less than 20 liters (hectare. Adjusting the speed of the electric motor 1 (Fig. 2) allows you to adjust the diameter of the droplets of the liquid to be dispensed.
    The hydraulic spraying system is equipped with a series of rotary nozzles 30 and 31, each of which is equipped with its own
    2139704
    turn, ring collector 32 and 33 of one of the types (Fig.1-4). This installation contains several pumps 34 and 35, which draw the developed liquid 5 in the receiver 36 by means of pipelines 37-39. Pumps 34 and 35 pump the sprayed liquid into pipes 40 and 41, feeding nozzles (not shown) of various rotary cylinders 30 and 31 by means of expanding cups 42 and 43 of a known type, intended to serve as flow regulators, and control electrofluor valves. 44 and 45. Each of them represents a solenoid valve of a known type in the inoperative position (Fig. 5), with which the corresponding pump, for example 34, pressurizes the fluid into the common return pipe 46 leaving the receiver tank 36, and in working position Corresponding pump delivers fluid to line 40.
    25 Receivers 47 and 48 of fluid recovery, which are coupled with collectors 32 and 33, respectively, are connected to receiver 36. 48-50 pipelines, in which
    3Q phase shifted check valves 51 and 52.
    In the second embodiment (Fig. 5), each of the pumps 34 and 35, coupled with the rotating nozzles 30 and
    5 31, is a peristaltic pump (Fig. 7). The various peristaltic pumps 34 and 35 have rotors, such as 53, placed on a common vadu 54, the ends of which 55 are placed freely rotating in the casing 56 using ball or roller bearings 57 and 58. The bearing 57 is the bearing of the end of the axis 59, the surfaces of which
     inside the casing 56 is matched with the corresponding end of the common shaft 54 through the free wheel 60, while its surface outside the casing 56 is matched precisely by bolts, such as 61, with the drive roller 62 of the drive hub 62. In the embodiment under consideration 63 is provided with a pneumatic tire 64, preferably
    55 is little or not inflated at all, and the assembly consisting of the casing 56, the shaft 54 and the hub 62 of the roller 63 is placed on the lever so that
    tire 64 of roller 63 is pressed, for example, with the weight of a knot to the periphery of a wheel (not shown) of a mobile pulverizer or vehicle that either carries it or tows it if it itself is equipped with supporting devices. .
    According to the invention, a peristaltic pump pump, such as 34 or 65, contains a deformable tubular element, such as 66 or 67, for example, from an extruded synthetic material, with a tail cross-section (6), a deformable tubular element, such as 66 of each pump 34 is placed in a removable cassette 68, with which tubular element 66 is tightly coupled. Each of these cassettes 68 has, in a section with a plane perpendicular to the common shaft 54, the shape shown in FIG. 7. Each cassette 68 or 69 is provided on the side of the common shaft 54 with a hole for passage of rotor parts, such as 53, of the corresponding peristaltic pump, which are intended to locally crush the tubular element 66. The rotor 53 of each peristaltic pump is formed by two disks perpendicular to common shaft 54 with clutches mounted on the shaft and using crushing rollers 70 and 71 mounted between the drive wheels of the respective rotor 53 in such a way as to form outside the cylindrical area rhnosti embracing both disks, you vystzshy sufficient expanse in order to crease, at least partially, the deformable tubular element 66 in its part located towards the middle sootzetst- vukltsey cassette 68, as shown in FIG. 7
    When the spraying installation advances, for example, by a tractor (not shown), the wheel of the installation or of this tractor on the periphery of which is located the pneumatic tire 64 of the drive unit.
    roller 63, causes the roller to rotate, and the direction of rotation of the freewheel was chosen so that the hub 62 of roller 63 rotates a common shaft 54, on which are delivered: the rotors of all peristaltic pumps. At each turn of the roller 63, other rollers, such as 70 and 71, placed on the rotor 53 of different peristaltic pumps, successively remove three times the cross section of the corresponding trz deformable base element 66, as a result of which each time a suitable roller is pumped the outlet side of the tubular element 66 (the fe direction of rotation, indicated by the arrow in Fig. 7) towards the outlet port 72 (Fig. 7). The flow rate of each peristaltic pump 34 is controlled by an appropriate expanding cuff 42, and the best spray uniformity over time can be obtained by shifting, for example, by 120 rotor rollers of two successively located peristaltic pumps.
    In the absence of slippage between the roller 63 and the wheel, to the periphery of which it is pressed, and between this wheel and the ground, the instantaneous speed of rotation of the rotors 53 of the peristaltic pumps is proportional to the rate of advancement of the mobile unit for spraying, which ensures at least approximate stability of the fluid volume sprinkled on a unit surface, despite the change in the rate of advancement, which inevitably, on uneven terrain.
    If the described spraying installation moves backwards, the freewheel 60 excludes the communication of the roller 63 during its rotation with the common shaft 54 and bringing this shaft, therefore, into the rotary motion of the rotors of various peristaltic pumps.
