30L-8 plant protection drone. High capacity and efficiency, upward folding arm improvement of D22L, higher performance powertrain with 8-rotors. Strong flight stability, extended wheelbase, megaflow peristaltic pump, higher spraying efficiency, real time regulating flowrate according to flight speed. Airframe dimensions is 3090mm*3090mm*830mm(incl. propellers). The maximum take-off weight can reach 77kg and can hold 30L of liquid. The flight time can reach up to 20 minutes, the maximum speed can reach 10 meters per second, 10L of liquid can be sprayed per minute, and it can continue to operate 18 hectares per hour. It is equipped with two 20000mah batteries, and the batteries are fully charged in 15-20 minutes. One charger can charge two batteries at the same time, which greatly improves the charging efficiency. The battery is an intelligent lithium battery with baked oil, intelligent power indicator, battery life indicator, intelligent charging alarm, intelligent storage function, automatic sleep function, software upgrade function, data communication function, battery log recording function, and intelligent balance function, etc. More efficient than ordinary batteries. The software upgrade system is connected to the computer through the USB interface to upgrade, and the upgrade is faster. It is more convenient to use USB serial communication, WiFi communication and CAN communication to record the real-time voltage, current and battery usage times.

The balance performance of the eight-rotor is better than that of the six-rotor and the four-rotor when flying. The design is more refined by folding up. It is conducive to rational use of space in transportation. Besides, high precision CPS and CNSS RTK Module. As the standard aviation system, GPS can meet most of the customers working demand. RTK module is an option for special crop or environment with centimeter level accuracy. RTK station module ensure the accurate working whenever and wherever possible. Using high dynamic receiver board card, even at high speed of 100km/hr, it can achieve centineter-level high-precission differential positioning results. And obstacle avoidance radar, front and back obstacle avoidance radar detect the surroundings in both side to identify obstacle(radium>=5cm) 20 metres away and detour around it automatically. The front and rear obstacle avoidance radar is more accurate than the ground defense radar, which can ensure the safety of UAV flight to a greater extent. The FPV 480p camera can more clearly grasp the flight situation when the drone is flying.
