METHOD OF LASER ACTIVATION OF SEEDS in clamps AND SYSTEM FOR ITS IMPLEMENTATION
Name of the inventor: Zhurba PS .; Dolgov AN .; Zhurba ETC.
The name of the patentee: Limited Liability Company "Agrolazer"
Address for correspondence:
Starting date of the patent: 1992.10.29
Usage: the invention relates to the field of agricultural and industrial crop can be used for pre-treatment of seeds, but also for the disinfection of seeds. SUMMARY OF THE INVENTION: In order to reduce labor costs and enhance productivity in processing large quantities of seeds in a silo, activated seed performed simultaneously in multiple zones collar.
DESCRIPTION OF THE INVENTION
The invention relates to the field of agricultural and industrial crop can be used for pre-treatment of seeds in order to stimulate sowing qualities and increase productivity, but also for the disinfection of seeds.
Methods are known for pre-treatment of seeds of cereals in static mode, comprising irradiating the surface layer of the seed laser radiation [1, 2]
The disadvantage of the methods is the need for special containers or additional space to accommodate storage facilities and processing of seeds in the surface layer, making it difficult to use the method for large batches of seeds and bulk turners.
There is a method of laser activation of seeds in a static mode, selected as a prototype, including seed processing by alternately transmitting light energy of the laser on fiber optics device to be installed in a variety of shoulder zone [3]
Known apparatus for laser activation seed directly in clamps chosen as the prototype, consisting of a laser source of 25-30 mW output power and a wavelength of 632.8 nm, at which the output window attached to the glass fiber optical waveguide nozzle 5-10 m ending special emitting tip [3, 4} By moving the laser oscillator along the shoulder seeds, the tip is dipped into the different points on the shoulder certain time and thus the seeds treated in static mode.
The disadvantages of the known method and apparatus are the laboriousness due to the presence of the operator, conveying the light guide tip with a shoulder different zones and low productivity due to the power loss of the laser beam at the output waveguide device.
The proposed solution is aimed at reducing labor costs and increasing productivity when processing large batches of seeds in a grain silo. This object is achieved by the activation of the laser scanning beam of seeds carried out through a series of light-guiding devices in the shoulder, through which creates a lot of energy bands at the specified activation mode, with control of the activation is automatic. The novelty of the device for implementing the method of seed laser activation is found that the mirror and the bottom lens diffusing the light guide at the top of the enclosure.
Search Results for proposed technical solutions are not only a prototype, but also with other solutions in the art revealed signs that distinguish the claimed solution to see what can be concluded about its compliance with the criteria of "novelty" and "inventive step".
The drawing is a schematic diagram of laser activation of seeds in a static mode.

The system for laser activation seed includes a laser light source 1, a wavelength of 632.8 nm and a power of 50 mW with a scanning device 2, allows you to scan an optical horizontal plane with a defined frequency. Laser light source 1 is provided with three lift for adjusting the height of the optical surface. The system includes a light guide device and consisting of a metal tube 4, the top of which the mirror 5 is set and the lower diffusing lens 6 comprising a conical mirror 7 within the optical sensor 8, with the ferrule 9. laser generator control unit 10 sets the activation mode is automatically , controls the beam scanning, performs switching on and off of the laser according to a predetermined operation. |
METHOD FOR ACTIVATION OF SEEDS carried out as follows
A series of light-guiding devices installed in different zones collar so that the mirror 5 is in the scanning plane of the laser beam. Mirror 5 align so that the reflected beam passed away inside the pipe and fell on the light-diffusing lens, creating pulses of light output of 10 mW / cm 2. The required activation mode is set seed with the electronic control unit automatically. The entire system is powered from the mains voltage of 220 V AC and a frequency of 50 Hz.
The resulting seeds of the energy in the irradiated areas collar transmitted to neighboring layers of seeds by contacting the irradiated seeds with non-irradiated. Therefore, a certain time interval between the end of treatment and planting seed in the soil.
Numerous experiments proved that depending on the crop variety, batch, and areas of cultivation, the processing mode is an individual parameter, and in each case is determined by physiological criteria (see. Table.).
The proposed method can be carried out under conditions granaries with less effort. Thus, laser activated seed in clamps of 100 m proposed method requires 10 days, while the laser activation seeds in clamps with the volume using a fiberglass fiber length of 10 m and a density of light at the fiber 2 mW / cm 2, provides activating a predetermined mode of seeds for 70 man-shifts.
