Precautions for selecting agricultural plant protection drones
The selection of agricultural plant protection drones directly affects the efficiency, effectiveness and cost of operations, and needs to be comprehensively considered from multiple dimensions to ensure an accurate match with actual needs:
Matching job requirements and machine models
Job scale adaptation : For individual households or small-area planting (within 500 acres), a drone with a load capacity of 10-15 liters is sufficient to meet the needs. Its body is compact and the operation is flexible, and a single person can complete the operation.； Large-scale operation scenarios (more than 1,000 acres) such as planting bases and cooperatives require models with a load capacity of more than 20 liters. Coupled with the multi-machine collaborative operation mode, the single-day operation volume can be greatly increased (a single machine can operate an area of 1,500-2,000 acres in a single day) and shorten the farming window period.
Crop Characteristics Adaptation : Low-growing crops such as wheat and rice have low requirements for UAVs to pass through, and conventional four-rotor models can do the job.； However, fruit trees and sorghum crops (corn, sorghum) need to choose models with obstacle avoidance functions and higher operating heights. For example, drones equipped with a 6-way radar obstacle avoidance system can accurately identify crop heights and maintain a safe distance (usually 1-2 meters) to avoid collision with branches while ensuring that the liquid can cover the middle and upper parts of the crops.
Adaptation to terrain conditions : The terrain in plain areas is flat, and ordinary GPS positioning drones can operate stably.； For complex terrains such as hills and mountains, you must choose a model with terrain following function. It uses millimeter-wave radar to scan the ground undulations in real time and automatically adjusts the flight height (the error can be controlled within ±0.3 meters) to ensure uniform spraying of the liquid and avoid leakage or re-spraying due to height differences.
Check core performance parameters
Balance between load and endurance : The bigger the load, the better. It needs to be judged comprehensively based on the battery life. For example, if a 20-liter load-bearing model is equipped with a 6000mAh battery, the battery life is about 20-25 minutes, and the single operating area is about 20-30 acres. The battery replacement must be convenient (supports quick plug-in and removal within 30 seconds), otherwise frequent battery replacement will reduce the overall efficiency. At the same time, attention should be paid to the cycle life of the battery (≥300 times) to reduce long-term replacement costs.
Spray system performance : The type of nozzle needs to be selected according to the crop. The centrifugal nozzle has a good atomization effect (particle size 50-150 microns) and is suitable for fine mist demand scenarios such as vegetables and wheat.； The fan-shaped nozzle has strong penetrating power (particle size 150-300 microns) and is more suitable for deep spraying of fruit trees and high-stem crops. In addition, the spraying flow rate adjustment accuracy needs to reach ±5% to ensure stable dosage per mu (error ≤80ml) and avoid waste or insufficient liquid medicine.
Flight control and intelligence level : The flight control system is the "brain" of the drone. It needs to have GPS + Beidou dual-mode positioning (positioning accuracy ≤ 1 meter), support autonomous route planning at AB point, automatic obstacle avoidance, breakpoint resumption and other functions to reduce manual intervention. Intelligent auxiliary functions are also very important, such as automatic return to home when the battery is low, real-time statistics of operation data (operation area, dosage of medication), etc., which can improve operational convenience and management efficiency.
Reliability and cost of use
Body material and protection : Give priority to the carbon fiber material body, which has high strength, light weight, excellent drop resistance (no structural damage after a 1.5-meter drop), and can adapt to the complex environment in the field. At the same time, the waterproof level needs to reach IP65 and above, and it can operate in light rain or high humidity environments to avoid sudden changes in weather that affect the farming season.
Consumable parts and maintenance : The warranty for core components such as motors and ESCs requires ≥ 1 year. Wearing parts such as propellers and nozzles should be cheap and easy to replace (no professional tools required) to reduce maintenance costs. For example, the price of a single high-quality propeller should be controlled within 50 yuan, and the service life should be ≥50 hours of operation.
After-sales service coverage : It is necessary to confirm whether the brand has service outlets around the operating area to ensure quick response (on-site delivery within 24 hours) in case of equipment failure. For remote areas, you need to know whether the brand provides remote technical support and backup machine services to avoid delays in equipment maintenance.
Jubailu Technology provides drone technical service support
With its professional technical team and complete service system, Jubailu Technology provides full-cycle technical support for users of agricultural plant protection drones to ensure smooth and efficient operations:
Pre-sales technical adaptation service
Requirements analysis and solution design : Technicians will have an in-depth understanding of the user’s crops, operating area, terrain conditions and other information, and develop a personalized selection plan based on the drone’s performance parameters. For example, for fruit tree planting in hilly areas, a 20-liter load-bearing model with terrain following and 6-way obstacle avoidance functions is recommended, and the optimal operating route pattern is planned.
Simulation testing and parameter optimization : Verify the operating performance of the aircraft model in specific scenarios through drone simulator or on-site small-area testing, including flight stability, spray uniformity, etc. According to the test results, adjust the nozzle angle, flight height, speed and other parameters to ensure accurate dosage per mu and the liquid adhesion rate reaches the standard (≥80%).
Sales operations and skills training
Full process practical training : Provide 3-7 days of systematic training, covering drone assembly and debugging (battery installation, nozzle calibration, GPS positioning activation), remote control operation (takeoff, landing, route adjustment, emergency shutdown), operation planning (region division, route setting), etc. The training adopts theory + practical mode to ensure that students can complete the homework independently.
Intelligent system application guidance : Guide users to skillfully use the supporting management APP, including operation data statistics (daily operation area, total dosage, battery consumption), equipment status monitoring (motor temperature, battery power, GPS signal strength), fault code interpretation (such as E10 indicating that the nozzle is clogged) and other functions to achieve intelligent operation management.
After-sales technical support service
Remote fault diagnosis and resolution : The smart module equipped on the drone can upload operating data in real time, and technicians can remotely view flight logs through the background system. More than 70% of common faults (such as gyroscope calibration deviation, poor battery contact) can be solved through remote guidance, without the need for on-site maintenance.
Quick repair and spare parts support : For faults that require on-site repair, the service team promises to respond within 12 hours, and the maintenance cycle for core components (flight control board, motor) is ≤3 days. At the same time, sufficient original spare parts are available to ensure timely replacement and reduce equipment downtime.
Regular technical upgrades and maintenance : Regularly provide users with drone firmware upgrade services, optimize flight control algorithms (such as improving obstacle avoidance response speed), and add new functions (such as multi-aircraft collaborative operation scheduling).
