Product overview
The Hongfei Reliable Agricultural Spraying Drone 72L Automatic UAV for Crop and Orchard Spraying is an agricultural flight platform identified in its structural description as HBR T72. Its eight-axis architecture combines an integrated carbon-fiber fuselage with aerospace aluminum construction. Payload is specified as 72L/75KG, with a maximum takeoff weight of 147KG and a listed aircraft weight of 51KG. The arms fold upward through 90 degrees for transport, and the aircraft is packed in an airline box.
The aircraft measures 3920mm*3920mm*970mm, with folded dimensions of 1050mm*900mm*1990mm and package dimensions of 2200mm*1100mm*960mm. Its agricultural integration centers on spraying, terrain-following radar and front and rear obstacle-avoidance radar. GPS positioning and autonomous flight support plot, edge-sweeping and fruit-tree route modes. Plot mode accepts 128 waypoints with adjustable altitude, speed, obstacle-avoidance mode and flight path. Terrain-following sensitivity can be adjusted to suit different crops and terrain.
Operating specifications give a flight altitude of ≤ 20m and flight speed of 1-10m/s. The spraying system has a rate of 8-15L/min, width of 8-15m and droplet size of 110-400μm, with spraying efficiency of 28-30ha/hour. The described power configuration pairs a 14S 42 000mAh lithium-polymer battery with a four-channel high-voltage smart charger capable of charging four smart batteries concurrently. Battery specifications are 60.9V when fully charged, 1000 cycles and a charging time of 30-40 minutes.
