Description

The utility model relates to the field of ecology and agriculture and can be used in the technological application of protective biological products when growing plants in closed and open ground.

Known devices for laser irradiation of seeds and plants containing laser radiation sources, beam scanning systems and control units [1-3] are unsuitable for laser processing of protective biological products, since objects receive unknown doses of laser radiation with random frequency and frequency. With the help of such devices it is impossible to establish and control the exposure of laser processing and radiation power density. The closest technical solutions are presented by laser installations for irradiation of plants in in vitro culture, which use a laser radiation source, a universal lens and a control unit [4-6]. They provide a precise setting of the irradiation parameters, however, these devices cannot be used in the technological application of protective biological products, since they have low productivity, high labor intensity of maintenance and can work only with a small volume of the working solution of protective drugs placed in small vessels.

The purpose of the utility model is to increase the productivity of laser processing of protective biological products while ensuring the required accuracy of laser irradiation in a flow-through mode.

This goal is achieved by the fact that an electromechanical unit with a pump motor for pumping a solution of protective biological products through a working container with plane-parallel transparent edges, a circuit for switching on the motor of an electromechanical unit and a sensor for the presence of a solution are additionally introduced into the device for laser processing of protective biological products, including a laser radiation source and a control unit in the working container, while the sensor for the presence of a solution in the working container is electrically connected to the control unit, and the control unit is electrically connected to the laser radiation source and to the motor switching circuit of the electromechanical unit.

The structural and functional diagram of the device for laser processing of protective biological products is shown in figure 1. The device includes: 1 - a laser emitter with a power supply, 2 - a control unit, 3 - a circuit for switching on the engine, 4 - a pump motor for pumping a solution, 5 - a working container with plane-parallel edges , 6 - sensor for the presence of a solution in the working container.

The device works as follows. At the operator's signal "General Start", the control unit 2 sends the "Start pump" command to the engine switching circuit 3, the engine switching circuit 3 supplies the preset supply voltage Un to the pump motor 4, which starts pumping the solution with protective biologicals through the working container 5. When a solution of a biological product appears in the working container 5, the sensor 6 for the presence of a solution is triggered and, according to its signal "Work", the control unit 2 gives the command "Start laser" to the laser power supply and turns on the laser emitter 1, which irradiates the area of space in which the working container 5 is located The solution of a protective biological product is continuously pumped through the working container 5 at a speed set by the engine switching circuit 3. The pumping speed is changed by changing the supply voltage Un of the pumping pump motor 4. At the moment of pumping out the last portion of the solution from the working container 5, sensor 6 records the absence of solution in the working capacity 5 and gives the command "General Stop" in b control unit 2. In turn, the control unit 2 sends the commands “Stop pump” to the engine 4 switching circuit and “Stop laser” to the laser power unit. As a result, the laser emitter 1 and the pump motor 3 are switched off. The unit switches to the standby mode for the next cycle of operation.

This design of the device helps to increase the productivity of laser processing of protective biological products in the liquid phase, while ensuring the required accuracy of irradiation parameters in a flow-through mode. Plane-parallel transparent edges of the working vessel allow minimizing the loss of laser radiation. The duration of the irradiation of the drug is set by the rate of pumping the solution through the working container. The constancy of the location of the working vessel relative to the output aperture of the laser emitters ensures the uniformity of the irradiation parameters in the entire volume of the treated solution, and the built-in sensor for the presence of the solution with the control unit ensures the autonomous operation of the device, which helps to reduce the labor intensity during the technological laser processing of large volumes of protective biological products.
