China Pesticide Drone Suppliers - 22L Automatic Spraying UAV with Centrifugal Nozzles for Agriculture and Fumigation Factory
Product Introduction
Over the farmland, agricultural drones are like intelligent painters equipped with "electronic eagle eyes", completing spraying operations with millimeter-level control accuracy that is comparable to surgical operations. Its RTK differential positioning system can achieve centimeter-level positioning, and with binocular visual obstacle avoidance radar, it can scan the height of crop canopies in real time during flight, so that the nozzle and the leaf surface always maintain the optimal atomization distance of 0.8-1.2 meters - this distance can ensure the uniform adhesion of droplets and avoid the drift and waste of liquid medicine.
With high-precision sensors and intelligent navigation systems, agricultural drones can accurately sense farmland topography, crop growth conditions and other information, thereby achieving precise quantitative spraying of pesticides and fertilizers. It can adjust the dosage and range of spraying according to the needs of crops in different regions, avoiding problems such as missed spraying and repeated spraying that may occur in traditional spraying methods, which not only improves resource utilization efficiency but also reduces environmental pollution.

High pressure nozzle operation mode
High-pressure nozzle
The high-pressure nozzle relies on a plunger pump or a diaphragm pump to pressurize the liquid medicine to 0.5-2MPa, and sprays it out at high speed through a nozzle with a tiny aperture (0.3-1mm), forming a high-kinetic energy penetrating mist flow. Its core advantage lies in the efficient coverage of complex scenes.
Centrifugal nozzle
The centrifugal nozzle generates centrifugal force through the high-speed rotating impeller, which throws out the liquid medicine and breaks it into uniform droplets. The core advantage lies in the precise and controllable atomization effect and the uniform droplet size (50-200μm). By adjusting the impeller speed (usually 3000-10000 rpm), the droplet size can be accurately controlled to avoid the uneven droplet problem caused by pressure fluctuations in traditional high-pressure nozzles.

Frequently Asked Questions
1. What is the positioning accuracy of the agricultural drone?
The drone utilizes an RTK differential positioning system, which achieves centimeter-level high-precision positioning. Combined with binocular visual obstacle avoidance radar, it guarantees safe and precise flight paths.
2. How does the drone maintain the optimal spraying distance?
During flight, the drone's sensors scan the crop canopy in real time, maintaining an optimal atomization distance of 0.8 to 1.2 meters. This ensures uniform coverage and prevents liquid drift or waste.
3. What are the key differences between the high-pressure and centrifugal nozzles?
The high-pressure nozzle relies on a pump to pressurize liquid up to 2MPa, creating a high-kinetic mist ideal for dense canopy penetration. The centrifugal nozzle utilizes a high-speed rotating impeller (3000-10000 rpm) to generate highly uniform, controllable droplets (50-200μm), preventing uneven distribution.
4. What is the tank capacity and efficiency of the AL4-22 model?
The AL4-22 model is equipped with a 22L pesticide tank, has a spraying width of 7-9 meters, and can achieve a high work efficiency of 9-12 hectares per hour.
5. Is the drone easy to transport and store?
Yes, it features an umbrella foldable design. When folded, the size is reduced from its spread dimensions of 2025*1970*690 mm down to a compact 860*730*690 mm, making it highly portable.
6. How does the drone handle complex terrain and wind conditions?
Equipped with advanced sensors, obstacle avoidance radar, and a flight control system, the drone adapts to varying terrain heights. It also features a strong wind resistance capability of up to 10m/s.
