A centrifugal spring is hollowed out in the middle of the friction plate. A silicon nitride ceramic centrifugal disc is provided below the centrifugal spring. The silicon nitride centrifugal disc is installed at the center of the centrifugal turntable.

[0007] Preferably, the nozzle outer end cap is composed of a frame base and a central boss, and the central boss has two first mounting holes in the middle.

[0008] Preferably, the motor end cover is provided with two second mounting holes.

[0009] Preferably, the nozzle motor and the ESC are provided with a mounting base above them, and an output shaft is provided at the bottom of the nozzle motor and the ESC.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] This utility model discloses an adjustable dual atomizing nozzle, comprising a nozzle outer end cover 1 and a motor end cover 2 installed below the nozzle outer end cover 1. A nozzle motor and an electronic speed controller 3 are installed below the motor end cover 2. The nozzle motor and the electronic speed controller 3 are installed inside the nozzle body shell 4. A 7075 aviation aluminum alloy spacer 5 is installed below the nozzle body shell 4. A friction plate 6 is provided below the 7075 aviation aluminum alloy spacer 5. A centrifugal spring 7 is hollowed out in the middle of the friction plate 6. A silicon nitride ceramic centrifugal disc 8 is provided below the centrifugal spring 7. The silicon nitride centrifugal disc 8 is installed at the center of the centrifugal turntable 9.

[0018] The nozzle outer end cover 1 is composed of a frame base 11 and a central boss 12. The central boss 12 has two first mounting holes 13 in the middle. The first mounting holes 13 are connected to the motor end cover 2 below by bolts.

[0019] The motor end cover 2 is provided with two second mounting holes 21. The inner side of the second mounting hole 21 is connected to the first mounting hole 13 by bolts, and the outer side is connected to the mounting base 31 of the nozzle motor and the electric speed controller 3.

[0020] The nozzle motor and ESC 3 are provided with a mounting base 31 above them and an output shaft 32 at the bottom. The nozzle motor and ESC 3 are embedded in the nozzle body shell and fixed by the structural space inside the shell, so that the motor and the shell form a whole.

[0021] The nozzle body shell 4 has four third mounting holes 41 around its upper perimeter. The outer side of the nozzle body shell 4 has an external threaded interface 42. The right side of the external threaded interface 42 has a positioning groove 43. The function of the third mounting holes 41 is to connect the nozzle outer end cap 1 to make the entire structure completely sealed. The external threaded interface 42 can be used to connect to external equipment, so that the adjustable dual atomizing nozzle can be used with external equipment. The function of the positioning groove 43 is to guide the alignment during assembly and assist in the quick installation of parts.

[0022] The centrifugal disc 9 is provided with a number of blades 91, which are mounted on the base 92. The function of the blades 91 is to transfer mechanical energy to the liquid. In the centrifugal disc 9, the blades 91 push the liquid to flow towards the edge of the impeller, and the liquid speed increases. When the rotation speed of the centrifugal disc 9 reaches a certain speed, the outflowing liquid can be atomized.

[0023] The 7075 aerospace aluminum alloy spacer 5 has the advantages of high strength, lightweight and corrosion resistance.

[0024] The silicon oxide ceramic swivel disc is resistant to high temperature and corrosion, has high structural strength, long service life, and low maintenance cost.

[0025] In use, the first mounting hole 13 of the nozzle outer end cover 1 is connected to the second mounting hole 21 on the motor end cover 2 by bolts. The second mounting hole 21 is installed on the mounting base 31 at the top of the nozzle motor and ESC 2. The nozzle motor and ESC 3 are placed inside the nozzle body shell 4. The third mounting hole 41 on the nozzle body shell 4 is connected to the frame base 11 on the nozzle outer end cover 1 by bolts, so that the nozzle body shell 4 forms a sealed whole. The lower end of the nozzle body shell 4 exposes the output shaft 32 of the nozzle motor and ESC 3. The output shaft 32 is sleeved with a 7075 aviation aluminum alloy spacer 5. A friction plate 6 is connected below the 7075 aviation aluminum alloy spacer 5. A centrifugal spring 7 is installed below the friction plate 6. A silica ceramic swivel disc 8 is provided below the centrifugal spring 7. A centrifugal turntable 9 is installed below the silica ceramic swivel disc 8. The blades 91 on the centrifugal turntable are used to disperse the liquid medicine. The adjustable dual atomizing nozzle of this utility model controls the motor speed through the motor and ESC control board, thereby spraying droplets of different sizes.

[0026] This invention improves the lifespan of the spray head by refining components and adds an automatic flow rate and atomization nozzle diameter motor control device, enabling multi-functional, multi-scenario intelligent adjustment applications. It atomizes pesticides into small particles ranging from 10μm to 400μm, allowing for better surface penetration and effective absorption and utilization. More precise flow rate and droplet size adjustment for different crops reduces pesticide waste and environmental pollution. The separate design of the spray disc and centrifugal motor avoids direct contact with pesticides, allowing for 42 days of continuous operation without wear and tear, doubling the lifespan compared to other spray heads.

[0027] This utility model provides an adjustable dual atomizing nozzle with high component strength, long service life, resistance to corrosion by liquid medicine, strong adjustability, and resistance to clogging during long-term use.

[0028] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
