The invention relates to devices for the pre-sowing treatment of seeds of agricultural crops, in particular cotton seeds.

The purpose of the invention is to increase the productivity and uniformity of processing of cotton seeds.

FIG. Figure 1 shows the dependence of the intensity of the electromagnetic field between the plates on the length of the radiated plate; in fig. 2 is a block diagram of an installation for high-frequency electromagnetic seed treatment; in fig. 3 - working chamber, general view; in fig. 4 shows section A-A in FIG. 3

The device for presowing treatment of seeds contains a high-frequency generator of sinusoidal oscillations in the form of an auto-oscillator 1, a preliminary cascade 2, an output cascade 3, a matching inductor 4 inductance, the inner lining 5 of the capacitor, the front and back walls of which are external capacitor plates 6 with integrated doors 7 for loading the seeds, the side, bottom and upper walls of which are the insulating frame of the working chamber 8, the indicator 9 for monitoring the power of the electromagnetic field, the coil 10 of the indication ora for controlling power of the electromagnetic field, the protection unit in the form of blocking switches 11 and power unit 12.

The device works as follows.

The irradiated seeds are placed between the plates 5 and 6 of the capacitor, while the blocking switches Ki and Ka are closed, the doors are closed, which in turn close the blocking switches KI and K2 and light the light bulb L. Using the power supply unit 12, the generator 1 is turned on at a frequency of 15 -16 MHz (power 1.2-1.5 kW) and using a variable inductance coil 4 set the maximum quality factor between the plates 5 of the capacitor (working volume), while the indicator needle 9 should be deflected as much as possible.

PRI me R 1. The working volume is 1 m (1.4 x 0.8 x 1.0 m). For seed treatment in standard agricultural packaging, in particular cotton seeds, 16 bags are placed between plates 5 and 6 on both sides, i.e. total weight 400-480 kg of cotton seed.

The generator is turned on and, by adjusting the variable inductance coil 4, the maximum value of the output power of the RF field to the irradiation chamber is achieved, since the quality factor of the chamber depends on the type of seed, their moisture content, contamination, etc.

For the initial determination of the processing time of a given batch, cotton seeds (AN-60) were kept in the RF field for various times.

The test results are shown in the table.

PRI mme R 2. The working volume between the plates 5 and 6 of the capacitor 0.4 m3 (1.4 x 0.37 x 0.8 m). In this case, the total weight of cotton seeds is 200-240 kg. The test results are shown in the table.

Example The working volume is 0.1 m (0.3 x 0.36 x 0.8 m). In this case, the total weight of cotton seeds is 50-60 kg. The test results are shown in the table.

As can be seen from the table, the optimal treatment exposure for the seeds of the cotton AN-60 is 5-6 minutes. The plant capacity for this grade is 10-100 kg / min.
