Description: The subject of the solution is a method of mixing pesticides and a mixer for mixing pesticides intended for use in agriculture to spray pesticides on agricultural crops. The pesticide agitator consists of four sections: the water supply section (1), the pesticide supply section (2), the mixing section (3), and the control module (4) are permanently connected to each other by means of hydraulic pipes (15) and connected to the control module (4) by electric wires (16). The solution uses a passive mixing process using a fluidic oscillator. The water and the chemical agent to be mixed are pumped into the oscillator in the chamber where these substances are mixed. The finished mixture can then be sprayed directly onto the farmland. This method of continuous mixing reduces the amount of unused pesticides, which in the traditional form are mixed up before spraying, and allows you to change the concentration of the mixture at any time.
The elements of the agitator are connected to each other by means of hydraulic pipes 15, and control system 4 is connected to the appropriate elements by means of electric conduits 16. The pesticide agitator consists of a water supply section 1, a pesticide supply section 2, a mixing section 3, and a control module 4. The water supply section consists of a water tank 5 of a shape that allows its complete emptying. The water tank is connected in series with the throttle valve 6, the pump 7, and the flow meter 8 using hydraulic pipes 15. The throttle valve 6 and the flow meter 8 are connected to control module 4 using electric wires 16. The pump 7 is powered by an external source and operates at a constant capacity. The amount of water pumped from water tank 5 is checked by the flowmeter 8 and controlled by the throttle valve 6. The control module 4 is responsible for controlling this system. The pesticide supply section 2 consists of a pesticide tank 9 which is shaped to be completely emptied. The pesticide tank is connected in series to pump 10, the flow meter 12, and valve 13 using hydraulic pipes 15. Pump 10 is powered by an electric motor 11. The flow meter 12, valve 13, and motor 11 are connected to control module 4 using electric wires 16. The flow meter 11 measures the amount of pesticide pumped by pump 10. The capacity of pump 10 is varied by controlling the rotational speed of the electric motor 11. A valve 13 allows the pesticide delivery module 2 to be disconnected from the rest of the system. Control module 4 is responsible for controlling all elements of the pesticide delivery system 2. The water supply section 1 and the pesticide supply section 2 are connected by hydraulic pipes 15 to the mixing module 3 in parallel.
