    The invention relates to a mobile liquid distributing apparatus comprising a quasi-constant flow supply device a variable flow distributing device, and liquid transfer means interconnecting the two devices. A flow regulating means is included in the transfer means and a regulation device acts on the regulating means and comprises comparison means. The latter receive, on one hand, a signal from means for measuring a magnitude which is a characteristic of the flow of the liquid in the transfer means and, on the other hand, a reference signal from means for measuring the speed of the apparatus through means for transforming between the speed and said magnitude. The means measuring the characteristic magnitude is constituted by a flow measuring means and the transforming means are constituted by means for applying a coefficient of proportionality. The invention is of particular interest in applications in the agricultural field.

    专利说明:

    The invention relates to agriculture, in particular to machines for spraying plants and soil with various treatment fluids.
    A device for liquid distribution is known; it includes a reservoir mounted on a movable chassis, a transverse bar with sprays: a pipeline with placed ng. there is a pump and a flow meter connecting the tank with the rod; a sensor of speed J connected to a wheel and a comparator, the inputs of which are respectively connected to a flow meter and through a converter with a speed sensor, and the pilot is connected to a pump P.
    However, the known device has a complicated design due to the use of electrical conversion means and the dosing accuracy is not high enough.
    The purpose of the invention is to improve the dosing accuracy and simplify the design.
    This goal is achieved by the fact that the device is equipped with a machining area counter, in conjunction with a speed sensor, and the bar with pliers are divided into sections
    organig sh, kalzdy of which svyzak through the breaker and the resistance store with kompampatopo n consumption meter.
    In this case, the sections of the soproteyzgleniya shop are mounted in parallel with the crust of the relay 5 coils that are connected to the locking bodies with rvn-i locks.
    In addition toto. the area counter on-connected with him schtchtrps imllul-s about in „
    The drawing of the drawing: vspnu; g device scheme for expanding the field: ;;
    The device is mounted on a self-starting psss 1 5 of the mouth of the wheel 2, the chassis contains a reservoir 3 for the liquid and a pump - connecting through a pipeline 5 to the reservoir 3; ; 1opet) ipalga 6 raede, on section 7 with splitters 8., The pump 4 is connected to the rod 6 of the pipeline 9, which terminates in the collecting chamber 10, the device also contains a 1 st installation, cHHLHi in Tnv6o854952
    the cable 12 to which the pipeline is connected 9. The locking organ 13 of the valve 1 1 pr 1 is activated by means of a mechanical connection 14 g by the control unit, turning off the engine 15 with automatic regulation of its operation depending on the speed of the comparator 16 POMOTSI.
    | 0 Ko1chparator 16 contains two inputs 17 and 18, the first of which is connected to a flow meter 19 installed in the pipeline 9 5 and the second with a speed sensor 20 operating
    15 from the rate-flow converting means 21 provided with the display unit 22. The second input of the charater 16 receives the reference flow sigals, on the basis of which the compiler generates the control
    instructions for the motor 15. The flowmeter 19 is made of a log: of an automatic type with a paddle blade 23. At the output of the flowmeter, a conversion of the torque of 24 to the voltage or current is set.
    Sensor 20 speeds in the form of a tachometer generator, installed on the carrier:
     wheel 25; which is moving
    Chassis 1 and is mounted on the auxiliary lassi 26, articulated with the first i connected to it by means of a compensating spring 27,
    Rod sections; -: 5 are separated from each other by locking bodies 28, to which are electrically connected; these interrupters 29 are closed, closed, or
    ,, Open the circuit., power supply coil relay 30, Anchors 31 relz are connected in parallel, respectively, sections of the shop 32 contact installed on the 17 of 17 of the scraper 16. The engine 5 is made pneumatic and contains two horizons of opposite cylinders fed two pipelines 33 with electro-valves 34 "Pipeline; 33 podsozdyken; to re-compressor 37. Hydrocyliidro piston rods act through mechanical link 14 on zeitil 11. Electro-valves 34 are connected by line no. 38 to you; one amplifier 39 provides the corresponding gain and power to match the valve 11
    3, by means of an engine 15, whose inlet is connected to line 40 at the output of comparator 16.
    To monitor the progress of the liquid splashing process, a flow totalizer 41 and a treatment area counter 42 are provided. The adder 41 consumption made in the form of the Converter 43 current-frequency, connected by a line 44 to the outputs of the flow meter 19 and the counter 45 pulse
    The machining area counter 42 is implemented as a current-frequency converter 46 connected by line 47 to the output of flow meter 19, pulse counter 48 and to resistance 49 connected to lines 47 and relays operated with control from interrupters 29.
    Pulse counter 48 provides the distance traveled, and the potentiometer, to which sections 7 of the boom 6 are connected, provides information about the irrigated area. In the pipe 9 has a three-way valve 50, the second outlet of which is connected by means of the drain pipe 51 to the tank 3.
    The device works as follows.
    854954
    The operator switches on the work of the non-coset, the required number of sections of the rods 6 with the help of locking bodies 28, then starts the self-propelled chassis. In doing so, the pump 4 and the compressor 37 are turned on. The speed sensor 20 provides the value of the speed of movement and saturates the current signal, transforming the means 21 into an indicator signal giving the Q formation about the optimum flow rate at this speed.
    The flow meter 19 provides a signal which, after its correction in the relay unit 30, converts the actual
    JC is the flow rate of each section of the boom 6. The difference between the two values of the signals from the comparator 16 is fed to an amplifier, which, depending on the sign of this difference, controls the contact of the solenoid valves 34,
    20 which causes the operation of the first or second piston rod of the engine 15, and therefore, the movement of the locking member 13 of the valve 1 i.
    five
    Once equilibrium is established, the flow rate of the fluid reaches an optimum value corresponding to the actual speed of the vehicle.
