A known installation for spraying liquids or irrigation, comprising a liquid reservoir, a pump with an adjustable valve placed in the pipeline, an installation speed sensor, a supply pipeline and a spray frame (1. The installation’s disadvantage is the need for high qualification and the high labor costs of the maintenance personnel. Most the technical solution to the proposed invention is a liquid sprayer on a self-propelled carriage, including a reservoir with a liquid, a pump for supplying liquid to a pressure line with a pressure sensor, a motor-controlled valve connected between the supply line and the tank parallel to the pump, a manifold with nozzles connected to the pressure line via a gate controller, the second input of which is connected to the tank and a motor control device by pressure sensor and sensor signals the speed set on the driven wheel of the trolley, as well as depending on the rate of fluid flow and the flow ratio of the nozzles G2.

FIG. 1 shows a spray diagram; in fig. 2 - microprocessor operation algorithm; in fig. 3 - block circuit of a digital electronic computing unit; in fig. 4 is a block diagram of a device for inputting data about the trolley speed and pressure in the pressure line. The self-propelled trolley sprayer contains a reservoir 1 for fluid connected by channel 2 to a pump 3 connected to a pressure line 4. The latter is hydraulically connected to collector 5, and the tank 1 is also connected to line 4 behind pump 3 to control channel 6, in which there is a control valve 7 connected to an electric motor 8 controlled by a digital electronic computing unit 9. The collector is also connected to reservoir 1 via channel 10. The hydraulic connection between channel 10 and pressure line 4 provides chivaets gate 11 of the liquid discharge regulator. The device is a digital electronic computing unit 9 connected to the sensor 12 speed trolley, interacting with non-driving wheel 13 and the sensor 14 pressure in the pressure line 4, as well as with the device 15 input data on the Q rate of fluid per unit area and the device 16 input data coefficient K flow nozzles installed on the collector 5. The devices 15 enter data on the rate of fluid flow per unit area and 16 - the flow rate coefficient foriCyHOK consists of elements with a core ;; discs. A control unit for digital indicators of trolley speed and pressure in the pressure line 4 is connected to digital indicators 17 and 18. Digital electronic computing unit 9 contains a microprocessor 19, an input-output register 20 connected to a device 15 for inputting data on the normal flow rate per unit area and a device 16 input data of the flow rate of the injectors by means of amplifiers 21. The data input / output register 20 is connected to the speed sensors 12 of the carriage and the pressure 14 in the pressure line 4 by means of the device 22 Yes, and with the valve 7 connected to the electric motor 8 by means of an output device 23 communicating with the data input / output register 20 via converters 24.
    Digital electronic computing unit 9 contains microprocessor 2 random-access memory 26 and long-term memory 27.
    The data entry device 15, which interacts with the sensors of the speed 12 of the carriage and the pressure 14 in the pressure line 4, contains a circuit of the driver 28 of the signals. The output of the signal conditioner 28 is connected to the input of the first circuit AND 29, the second input of which is connected to the synchronization wire 30, which selects the speed sensor-12 of the carriage or pressure 14 in the pressure line 4, It also co voltage circuit voltage converter 31, input which is connected to the output of the pressure sensor 14 in the pressure line, the output of which is connected to the second input of the second circuit AND 32 via the second driver 33, and the second input of the circuit 32 is connected to the wire 30 (bus) of the sensor selection synchronization by inverting ra 34 outputs AND circuits 29 and 32 are each connected to the input from the OR circuit 35, whose output is connected to the register 20 via the monostable multivibrator 36.
    The output device 23 for controlling the valve 7 and the motor 8 consists of a transistor amplifier power stage.
    The control device operates according to the algorithm shown in FIG. 2, The device consists of a block 37 for determining the required flow rate Q, a block 38 for determining the flow rate K of collector nozzles, depending on the number of nozzles, fluid density, nozzle type (nozzle diameter, etc. unit 39 for determining the actual velocity V of the atomizer; unit 40 for determining the required (calculated) distance P j-gj - according to the basic equation solved by a microprocessor;
    O.K,
    V
    where K is the proportionality coefficient (constant), of the unit 41 for determining the actual pressure P, in the pressure line; a unit 42 for comparing the calculated actual P pressures, which may have a tolerable mismatch to prevent continuous correction and auto-oscillations; comparison unit 43; output unit 44 for reducing pressure P and output unit 45 for increasing
    no pressure r ..
    The spray works as follows.
    After the operator enters into the control unit data on the required flow rates per unit area and parameter K using the input devices 15 and 16 and the operator sets the required speed of the atomizer, the pump 3 is started and the sputter 11 is set at a certain position.
    When the main process parameter Q deviates from the norm, the pressure in the line changes (these parameters are related by alphabet) and, depending on the actual speed, the microprocessor via output blocks 44 and 45 gives a command to the drive motor 8 to change the pressure P and thereby - to adjust the flow.
    Indicators 17 and 18 display actual speed and pressure data, based on which the operator can manually adjust pressure and speed of movement.
    The input device circuit allows; Sampling a sensor that is to transmit information to the microprocessor. In this case, the sensor sampling signal is applied to the conductor 30 in such a way that when the AND circuit 29 receives in binary code 1 at the corresponding input, the AND circuit 32 receives O due to the presence of an inverter 34
    In this case, only the speed sensor signal is transmitted by the AND 29 circuit to the OR 35 circuit and to the driver (standby multivibrator) 36, which converts them into a sequence of 5 pulses, in which the duration between two pulses is inversely proportional to the measured value. These pulse sequences are fed to the input of the converter (interrupted by the input node) 24. Signals from the pressure sensor 14 are selected in a similar way when the sampling signal in the conductor 30 takes the O value in binary code 5, which causes the I 29 circuit to lock and unlocking circuit AND 32.
    The time measurement between the two output pulses of the standby multivibrator 36 is provided by an increment in a time counter (not shown).
    The operation of the control unit and the sleep microprocessor from the above;
    algorithm (Fig. 2).
    The use of digital electronic control circuits makes it possible to control the flow rate with a large amount (up to centilitres), take into account any number and type of nozzles, and significantly increase the speed of perturbation testing. The operations that must be carried out by the operator are reduced to determining the Q amount of the sprayed liquid per unit area and the K value corresponding to the type of nozzles. All other operations are fully automated. At the same time, the necessary control parameters are displayed on the display panel of the visual display in digital form, which creates additional convenience in service.
    Using the proposed device, it is also possible to use any special nozzles, for example, with very large dimensions, which allow spraying of fertilizers in the form of a suspension.
