Why is the plant protection UAV labeled as "green"
nowadays, if there is any agricultural plant protection UAV entering, please eliminate it in time or notify the company In the prosperous era, its characteristics of high efficiency, precision and green environmental protection are recognized by the public. But most people do not know why plant protection UAVs are labeled as green
1. Small size, light material and small size mean that less materials are used when making. At present, the largest plant protection UAV in China has a diameter of 5 meters and weighs 136 kilograms, while an ordinary traditional agricultural machinery must reach at least 1000 kilograms
the use of composite materials can reduce the weight of the fuselage. Traditional unmanned plant protection machines are mostly made of metal materials such as aluminum alloy. With the popularization and application of composite materials, their characteristics of high specific strength and specific stiffness, small coefficient of thermal expansion, strong fatigue resistance and vibration resistance are favored by manufacturers. In addition, compared with the traditional metal materials according to the prediction data of April group and our estimate, the weight of UAV structure can be reduced by 25%?? At the same time, it increases the payload and improves its own safety
carbon fiber composites with high strength and light weight are widely used in UAV manufacturing. Carbon fiber pipes can largely replace the use of aluminum alloy pipes in the fuselage mechanisms and components of plant protection UAVs by pultrusion, winding or air blowing. In addition, the production technology of carbon fiber pipe has been very mature. It can produce various profiles through different molds. It can not only customize different wall pipe shapes, lengths, wall thicknesses, etc. according to individual needs, but also choose different methods such as surface 3K lines or painting for packaging and beautification in the post-processing process. At the same time, the mass production method can also effectively reduce product costs
2. Precise Fertilization and high utilization ratetherefore, it has a high degree of flexibility and productivity.
2015, China's use of chemical fertilizers and pesticides ranked first in the world, but the utilization rate of chemical fertilizers and pesticides was 15%-20% lower than that of developed countries. It is imperative to reduce the use and improve the utilization rate. In 2016, China made great efforts to fight the tough battle of agricultural non-point source pollution control, deepened the application of green prevention and control technology, continued to see zero growth in pesticide use, and approached zero growth in fertilizer use for the first time since the reform and opening up. The prosperity of agricultural plant protection UAVs in 2017 has further driven a number of pioneers of precision agriculture to improve the utilization rate of pesticides and reduce the use of pesticides through the precise spraying of plant protection UAVs
most farmers control diseases and pests in a decentralized manner. The pesticide dosage is not concentrated, which can not be reasonably and fully utilized. Moreover, most farmers have not received special training in field application. The research team led by Ivan varasoek has prepared carbon composite materials with a single atom thickness of 2 inches square, causing a large waste of pesticides. At the same time, the operation efficiency of the traditional small spray is low; Heavy fog drops and large volume spraying lead to low pesticide utilization efficiency. Therefore, agricultural fertilization urgently needs to use efficient and advanced medical equipment to improve the utilization rate of pesticides
plant protection UAV is easy to learn and operate. Generally, the operators can master the essentials and perform tasks after about 30 days of training. As long as they stand on the ground and operate through the remote control, the plant protection UAV can complete the insect eradication of hundreds of acres of crops in one hour
plant protection UAV adopts low volume spray technology. In the process of spraying, the liquid medicine is dispersed by the action of the UAV atomizing parts to form fine droplet particles with high coverage and good permeability, which can make the best effect of the medicine and give full play to the advantages brought by the particle size, so as to achieve the purpose of precise prevention and control of diseases, pests and weeds
3. Green environmental protection and high efficiency. The agricultural plant protection UAV is small and its load capacity can reach kg. Generally, the UAV with 10L medicine box can be divided for 10 minutes at a time, and the operation area can reach about 300 mu. However, it takes about 30L of prepared pesticides to fertilize one mu of land manually. According to statistics, the spraying efficiency of UAV is times that of traditional manual operation, and the pesticide consumption and water consumption are at least 50% and 90% less than those of traditional manual operation
there are two types of plant protection UAVs in the market: electric and oil powered. It is needless to say that the electric motor is light and cheap, which must be a green energy. However, the oil power thinks that the motor has some disadvantages, such as insufficient power and short endurance. Although both sides have been difficult to accept each other and quarrel endlessly, compared with traditional large-scale agricultural machinery, its power consumption and fuel consumption can be regarded as green environmental protection. For a simple example, black smoke will be emitted from the seeder working in the field as soon as it is started. However, if the unmanned aerial vehicle (UAV) that sows seeds smokes when it works, it will not work
the above are only some advantages of the agricultural plant protection UAV, but these advantages have proved that the plant protection UAV industry can be expected in the early stage, which is worth promoting
