China 22L Pesticide Drone - Automatic Agriculture Spraying UAV with Centrifugal Nozzles - Factory Direct from Suppliers
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 (FAQ)
1. What is the positioning accuracy of this agricultural drone?
The drone utilizes a high-precision RTK differential positioning system to achieve centimeter-level positioning accuracy, enabling millimeter-level control for precise spraying operations.
2. How does the binocular obstacle avoidance radar work?
The binocular visual obstacle avoidance radar scans the crop canopy height in real time during flight, ensuring the drone maintains an optimal atomization distance of 0.8 to 1.2 meters from the leaves to prevent drift and waste.
3. What are the main differences between the high-pressure and centrifugal nozzles?
The high-pressure nozzle pressurizes liquid to 0.5-2MPa for high-kinetic energy mist flow, ideal for complex crop penetration. The centrifugal nozzle utilizes high-speed rotation (3000-10000 rpm) to break liquid into highly uniform droplets (50-200μm) for precise and controllable coverage.
4. How efficient is the AL4-22 drone during spraying operations?
The AL4-22 model has a spraying efficiency of 9 to 12 hectares per hour, featuring a spray width of 7 to 9 meters and a maximum flow rate of 3.5 to 4 liters per minute.
5. Is the drone easy to store and transport?
Yes, it features an umbrella foldable structure. When spread out, its dimensions are 2025*1970*690 mm, and it folds down to a compact size of 860*730*690 mm for easy transportation.
6. What is the tank capacity and take-off weight of the AL4-22 drone?
It is equipped with a 22-liter pesticide tank. The drone has a net weight of 19.5 kg and a maximum take-off weight of 55 kg.
