1. Simple operation and low failure. 2. Spray width: 3.5-4.5 meters. 3, GPS positioning: There is autonomous take-off function (when the plane takes off, just push the throttle can be). The height can be set, and when the voltage is too low, there is an automatic alarm function. 4, each spray area: 20-40 acres during the day, 10-20 acres at night, 1 minute for 1 minute Eight-rotor agricultural drone technical indicators Dimensions (length * width * height) 2110 * 2110 * 800mm Aircraft weight 11KG Maximum takeoff weight 30KG Pesticide container capacity 10L Boom length 220cm Body Material Carbon Fiber & Aluminum Alloy Charger High-power lithium balance charging device Spraying system, medicine box, diffusion spray system, booster pump Operating temperature -10°C-40°C Lithium battery life 300 times charge and discharge Maximum payload (5-20) KG (±5%) Lithium polymer power battery 22.2V/16000mA / battery life 10min Working speed 3-8m/s (wind speed 2-3) Relative flight height 1-3 meters from crops (depending on different crops) Spray width (6 0.3L/min nozzles, 2.2 meters long spray tube) 2-4 meters (downwind or upwind, wind speed 2-3) Spray flow rate 1-1.2L/min (6 nozzles) High-concentration pesticide consumption 0.5-1.0L/mu (depending on different crops) Single machine spraying operation efficiency of 300 mu / day (depending on the actual operation of the flying hand)
