Product overview
The Hongfei 25 Liters 25 Kg Load Intelligent Flight Control Agricultural Spray Drone, identified as the HBR T25, is an agricultural flight platform for liquid spraying and solid fertilizer spreading. Its liquid payload specification is 25L, with a spray rate of 6-10L/min, a working width of 4-8m and droplets of 110-400μm. Spraying efficiency is 10-12ha/hour, while flight speed spans 1-10m/s. Its intended applications include large farmland areas and fruit orchards, with separate planning modes for plots, boundaries and fruit trees.
The physical architecture combines a carbon-fiber body with aluminum-alloy landing gear. Overall dimensions are 2010mm*1980mm*750 mm, compared with transport dimensions of 1300mm*1300mm*750mm; weight is 16KG and maximum takeoff weight is 51KG. A quick-plugging bucket supports refilling, with a stated 50% reduction in refill time. Integration centers on a modular spreading system with quick installation and removal. That system handles particles from 0.5 to 5 mm, provides up to 15 meters of spreading width and supports IP67 protection. The aircraft is packed in an airline box.
The operating configuration combines flight control, GPS positioning, autonomous flight, terrain-following radar and front and rear obstacle-avoidance radar. Plot planning supports 128 waypoints, while terrain-following sensitivity can be adjusted for crops and terrain. Power equipment comprises a 14S 42 000mAh lithium-polymer battery and a four-channel high-voltage smart charger capable of charging four smart batteries concurrently. Battery voltage is 60.9V when fully charged, charging time is 30-40 minutes and battery life is 1000 cycles. The 25L payload figure specifies liquid capacity; solid spreading has its own particle-size and throughput limits.
