Description

FIELD OF THE INVENTION The invention relates to agricultural machinery and can be used in square-nesting sowing without measuring wire. Known square-nested secs include grain tanks with sowing devices, photoelectric sensors, an amplifier, a relay, control of the operation of valve electromagnets, and a device with a device for ejecting fl marking material. The disadvantages of the known crops are the low quality of sowing and the complexity of the design. The closest in technical essence to the present invention is a square-nest seedling, grain bins with sowing devices, a cage for tags, sowing valves and a device for controlling the emission of tags, including sensors of tags, connected to the control unit of electromagnets of sowing valves f2. A disadvantage of the known crop is the low economic efficiency, since the costs of applying a radioactive substance, storing it, as well as installing an additional bunker with a sowing apparatus are necessary for marking. In addition, the storage of radioactive substances, as well as working with them is unsafe for staff. The purpose of the invention is to increase economic efficiency and improve the working conditions of service personnel. This goal is achieved by using one of the seed hoppers as a bunker for tags, the latter being equipped with a preheater, and using infrared radiation datasets as sensors of the tags.

FIG. 1 is a diagram of the crop in FIG. 2 is a functional circuit diagram for controlling tag outliers.

Square nesting sprout (Fig. Contains a device for controlling the emission of tags, including sensors 1 tags installed from the line-valve 2 seeding grain at a distance equal to the width of the spacing, the electronic control unit 3, which turns on the electromagnet 4, which acts on the valve of the grain seeding mechanism 2. The heater 5 Spologrev is produced by exhaust gases) is installed in one of the hoppers 6 seed seeding. The device also contains a vomer 7.

The electronic control unit consists of the amplifier 8, the trigger 9 of the system 10 controls the right sections of the splitter, the system 11 controls the left sections of the splitter.

The tag sensors 1 (Fig. 2) are infra-red, low-inertia sensors 12-15 included in the Winston bridge. The sensors 12 and 15 of the half-bridge are active and are installed along the line of the opener (Fig. 1) of the section of the split in which the heating of the Zerng is carried out.

The sensors 13 and 14 (4) ig.2 of the half bridge are compensatory and are installed from the opener line. Active sensors 12 and 15 half-bridges (Fig. 2) are shunted by resistors corresponding to,.

buttons to. Powered by sensors from a separate source of 16 constant current. The amplifier is designed to amplify signal signals from the sensor system. The trigger alternately turns on the systems 10 and 11 of the section control. The inputs of the control systems are connected to the trigger outputs. The control systems of the section of sections consist of a standby multivibrator 17, whose input is connected to one of the trigger outputs (Fig. 2). The standby multivibrator output is connected to the input of an electronic relay 18, which activates the seed sowing electromagnet (Fig. 1 ).

The device works as follows.

In one of the bins 6, the preheater 5 is used to heat the grain at 3-4 ° C above the ambient temperature.

r and R 2 (the magnitudes of which are less than the minimum resistance values of the infrared radiation sensors 12-- 5) of the sensors 12 and 15. As a result, an imbalance occurs (Winston bridge, and the unbalance voltage goes to the counting input of the trigger 9. The trigger is switched from one stable state (in which it is before the signal from amplifier 8 is supplied to its input) to another steady state, and on one of its outputs a signal appears that is fed to the input of the standby multivibrator of that section control system, whose input is busy with this trigger output 9.

For example, the signal is fed to the input of the multivibrator 17 of the system 10. In this case, the standby multivibrator 17 is started, and at its output a signal appears that is fed to the input of the electronic relay 18, which turns on the electromagnets 3 of the sowing mechanism of the seeds (I). After a certain time equal to the waiting time of the standby multivibrator 17 and sufficient for seeding the grain, the standby multivibrator returns to its original state and at its output the signal disappears.

 At the input of the electronic relay 18, the signal does not appear, and it turns off the electromagnet 3 of the seed sowing mechanism. When the sensors 12 and 15 get into the zone of thermal radiation of the evicted ones heated in one of the grain bins 6 as the seed moves, the bridge is balanced and the unbalance signal is fed to the input of the amplifier 8 and the process repeats. Only now the trigger 2 goes into a new steady state, and the system 11 controls the left sections of the split.

Using one of the bins as a hopper for tags and supplying it with a subject, also using sensors of infrared radiation as sensors allows you to use sown grain as tags, which will increase the economic efficiency of the crop and improve working conditions by eliminating a number of operations with a radioactive substance.
