These are due to the fact that between the outputs of the amplifiers and the inputs of the alarm unit of the control unit for the operation of seeding machines of the row crop, a multi-channel conversion circuit is included, consisting of inverters connected through the AND elements to the inputs of the OR element, and the second inputs. the AND yodklyuchenY to outputs of code converters having an input with an input switch Runciman zyakvogo indikagor a and rtapartrtensHo ch1erez binary counter with the main BbixodSh switch frequencies, the outputs of which are connected to the output of OR and generatschrami low and sound frequencies, and supplementary its input connected to the control The inputs of the switch are ё:: imeg familiar: the indicator and an additional element, And the second input of the latter is connected to the sound frequency generator, thanks to this kdast-. to a ructive decision with simultaneous termination of yysev in two or more Zh1 vash | Zh Shar 1atMot rSher Sh

It is not necessary to determine in which the Yyonshshgäva Schöydyarite the failure occurred and to significantly reduce the time for the qrbicKa f ® of a serviceable sowing apparatus.

In the drawing, flaifta is a schematic diagram of the proposed device.,

The device for controlling the flow of the propelling apparatus consists of photbile sensors I, each of which is installed at the output of the corresponding sowing device 2, which is assigned for height 1 of 1 dead seeds 3. Each sensor 1 contains 4 power connected to the source terminals) illuminators 5 and photoconversion circuit 6. The circuit breaker of the unit 8 for checking the serviceability of the device is connected to the power supply circuit of the illuminators. The transducer is shunted by a switch 9 of the test mode. The internal control device has an output of each sensor 1 of the iTycHJMTenJo 1.1.GSWP bypass with a capacitance 11. The output of each amplifier 10 is connected to the corresponding input inverters 12 of the multi-polarization 13 conversion. In this embodiment of the device, the conversion circuit 13 comprises three channels. The outputs of the input inverters 12 through the corresponding elements And 14 are connected to the inputs of the element OR 15. The second input of each element And 14 is connected to the corresponding output converter 16 of the code. Item output

OR 15 is connected to a switch 1.7, a frequency, one input of which is connected to a low-frequency generator 18, and the other to an audio frequency generator 19. The main output 20 of the frequency switch 17 is connected to the input of the binary counter 21, and the auxiliary output 22 is one-time with the switch 23 of the sign indicator mode and with the input of the additional element 24, the second of which is connected to the audio frequency generator 19. The output of the binary counter 21 is ready at a time to the converter 16 of the code and to the switch 23.

The alarm unit 25, the co-worker of the evuk’s 26, connected by b output

an additional element AND 24, as well as a sign indicator 27 connected via a decoder 28 to the switch 23 of the conversion circuit 13.

The device for controlling the bots of seeding machines of the seeding machine works in the following way.

During operation, the illuminators 5 photoelectrically 4 sensors 1 emit a light flux. Arrive at the upper unit 2 seed 3, the light flux is interrupted, resulting in 6 flashes of light on the photovoltage transducer. Photoconverter 6 generates current pulses supplied to amplifier 10 and then its output to capacitance 11. Capacitance 11 is charged, the signal arrives at the input of inverter 12, O appears at its input, which leads to Nalych Tire elements And 14. Therefore, the output of the element OR 15 will also be O, i.e. CONTROL The signal on the 17 frequency switch is missing. At the same time, at the main output 20 of the switch 17, audio frequency signals appear, KCfTOpbеttoypayt to the input of the binary counter 21. On the BtfXOfle of the last one, in the binary code, the count from the number of the last headpiece (in

 in this case from one to three). This account is fed to the input of the converter 16 code. At each output of this transform, a spruce in time appears I, arriving at the second input elements AND 14. At the same time, at the additional output 22 of the switch 17, the signal from-. absent, t, e. on switch 23

and on the additional element AND 24, the control s. signal does not stop. This causes 1 that signals from counter 21 do not pass to sign indicator 27 and sound emitter 26. Sound and light indications O1 are not present. If the flow of seeds coming from any sowing unit 2 stops, the flashes of light falling on the photovoltage converter 6 stop. The current pulses do not flow to the amplifier 10, as a result of which the capacitance is 11 parts and the input to the inverter 12 of this channel is O. At its output, 1 appears, arriving at the input of the corresponding element AND 14. The second input of the same element AND periodically receives 1 from the converter 16 of the code. Consequently, at the output of this element AND 14, Wits 1, which, having passed through the element OR 15, provides the control signal of the switch 17. As a result, at both outputs 2O and 22 of the frequency switch 17, low-frequency pulses appear at the input of the double counter 21, as well as to the control input of the switch 23 and to an additional element of AND 24. During the resistance of this pulse, the code of that seeding device, where it is bbices, is saved at the output of the counter. When the control signal is present on the switch 23, the signal from the counter 21 is fed through the decoder 28 to the sign indicator 27, where the seed meter is displayed, in which the seed is stopped. At the same time, through the additional element I 24, the sound emitter 26 is sound. In the case of stopping the flow of seeds coming from two or more sowing devices, the device works in the same way as described above, with the only difference that several inputs of the ITZI15 element are successively received in time from the corresponding AND 14 elements. Consequently, on the sign indicator 27 successively with the frequency of the low frequency generator, the numbers of the sowing apparatus are highlighted, where the sowing has stopped.

In the event that, during the operation of the crop, one or several cavities between the illuminator and the photoconverter are clogged with seeds, soil, or any other foreign objects, for example

measures, burlap, as well as when illuminating, the luminous flux does not flow to the phototransducer.

In this case, the latter does not generate

5 current pulses, resulting in an I output at the inverter output, and the device works the same as in the case described above, when the flow of the seeds is stopped in one or more of the sowing devices.

 When using the proposed device, the work culture is improved, the working conditions of the operator are improved.
