AL4-20 Agricultural Spraying Drone
A compact 20 L four-arm crop-spraying platform for flexible field operations.
AL4-20
Compact intelligence for precise crop protection.
A 20 L intelligent spraying platform for medium-sized farms. Dual centrifugal nozzles deliver a 7–9 m spray width and 9–12 ha/h operating efficiency with fine, uniform atomization.
Autonomous flight, terrain following, radar obstacle avoidance and FPV monitoring maintain reliable performance across varied fields. The foldable airframe, H12 controller and 3000 W fast charger simplify transport and deployment.
Wheat, Rice, Corn & Soybean Fields
Rapid, large-area application for pest and disease control, herbicide spraying and foliar fertilization across connected field-crop operations.
Orchards & High-Value Crops
Configured for apples, citrus, grapes, mangoes, tea and other orchard crops. Suitable for undulating and mountainous terrain, supporting insect control, disease management and foliar feeding.
Specialty Commercial Crops
Flexible application for potatoes, cotton, sunflowers, tobacco, vegetables and crops of different heights. Uniform atomization supports weed control, disease prevention and foliar nutrition while reducing crop-damage risk.
Pre-Sowing & Late-Season Applications
Supports pre-sowing residual herbicide application, coordinated pest and disease control during mid-to-late growth, and ripening or defoliation treatments near harvest.
Large Ranches & Grasslands
Covers grassland pest protection, locust and insect biological control, weed management and foliar fertilization. UAVs can reach areas inaccessible to ground vehicles and provide broad, consistent coverage.
