Under the background of the country's strong support for the three rural areas, more advanced plant protection drones are more widely used in agricultural production, which is an inevitable requirement for promoting agricultural development.
In line with the new trend, the plant protection drone industry has ushered in the most favorable development opportunities. At present, there are already many companies that have launched 5KG and 10KG models. However, with the changes in the market, single and low-load models have not met the demand, and the development of the industry requires more new changes.
Based on the actual situation of the market, Lai Shenglong launched a series of heavy-duty products. Because the three innovative and practical technologies have well met the market demand, once they were launched, they received a strong response. As of the end of December 2017, there were nearly 3,000 pre-sale orders, and the amount was close to 500 million yuan. .
So, what are these 3 major technologies? This includes large load technology, motor technology and multi-rotor technology.
How to improve the load capacity of plant protection drones has always been a difficult and painful point in the entire industry. Because this means that there must be innovative technology to ensure that the associated performance can be improved while improving the load capacity, such as stability, endurance and so on.
Lai Shenglong's first generation of products has achieved a breakthrough in large-load technology, and developed a 3WD-LSL-6-15L plant protection drone with a load of 15 kg.
After that, Lai Shenglong continued to make breakthroughs on the basis of 15L, and successively developed 3WD-LSL-8-30L with a load of 30 kg, 3WD-LSL-18-65L with a load of 65 kg, and 80 of the first in the country. The kilograms of drug liquid load plant protection drones have achieved technological leadership!
At the same time, it has also developed a mist sprayer and a spreader that sprays fruit trees. It is close to its peers in terms of product innovation and development speed.
The successful development of four levels of plant protection UAVs has been introduced to the market. On the one hand, it can meet the needs of plant protection services in different regions and different users. For example, 65L plant protection drones can spray 3,000 to 4,000 mu of land per day for large farmland operations. It is undoubtedly the gospel!
On the other hand, the emergence of higher performance products is bound to promote further innovation in the entire industry.
The problem of load capacity is, in the final analysis, a problem with the motor. To completely break through the bottleneck of the load, it is necessary to design a special motor for it and improve the performance of the motor. Lai Shenglong is following this principle and concept to carry out product research and development.
Under the technical support of first-class aviation colleges and experts from Beijing University of Aeronautics and Astronautics, Harbin Institute of Technology, West China University of Technology, and China Southern Airlines, Lai Shenglong independently developed a motor with complete intellectual property rights, providing preconditions for achieving heavy liquid load and becoming a plant protection drone. An unprecedented innovation in the field.
What is the obvious advantage of Lai Shenglong's motor? In addition to the advantages of light weight, small size, and strong relay and labor saving, it is mainly reflected in two aspects.
First of all, it has the advantage of long-term continuous operation. Generally speaking, the working mode of the general RC motor is intermittent, and the plant maintenance operation of the UAV is continuous working. The intermittent time of stopping the dosing is not enough to restore the motor to a normal state and continue working for a long time. It is easy to have problems. The motor developed by Lai Shenglong can run continuously for 3,000 hours.
Second, the service life is long. On the power system, a 22000 mAh lithium battery with a special discharge rate of 20 times is used to improve the life of the motor. On the central steering gear structure, a force reduction mechanism consisting of a bushing and a steering wheel is added. At the same time, a motor waterproof bubble line and a shockproof partition of the medicine box are added to improve the stability, safety and service life of the steering gear.
In terms of model structure, plant protection drones can be divided into single rotors and multiple rotors.
The advantages of a single rotor are outstanding, but there are also a lot of short boards. For example, the most reactive, it is difficult to operate, the need for more complex and higher-level flight control system, and the price is 2-3 times more expensive than the multi-rotor.
In comparison, the multi-rotor UAV has the advantages of simple structure, stable flight, easy operation, convenient maintenance, no oil residual pollution, and simple control. The general flight control can meet the demand, and is more suitable for the current agricultural development in China. The status quo has therefore been increasingly used in the field of plant protection drones.
The advantages are obvious and the shortcomings cannot be ignored. One of the biggest drawbacks of multi-rotor plant protection drones is that all the movements in flight are mainly achieved by adjusting the rotational speed of the blades, so that the adjacent two blades rotate in the opposite direction, and the wind field between them Will interfere with each other, causing a certain wind field disorder, which is not conducive to the spraying of drugs.
Lai Shenglong's heavy-duty plant protection drone, the maximum number of rotors can reach 18, then how to solve this problem?
One of the most important solutions is to build an efficient spray system with a professional windproof nozzle. With the help of the preset nozzle, it can effectively reduce the fog of the rotor by the rotor airflow, reduce the invalid spray and improve the spraying effect.
The research and development of technology and the upgrading of products are not for self-respect, but for better helping agricultural producers and promoting the development of modern agriculture. After the successful development of Lai Shenglong plant protection drone series products, it made a strong response in the market.
Laisheng Longye has completed 10 billion projects in four major agricultural provinces in Henan, Heilongjiang, Jilin and Xinjiang, and has also developed and sold markets in Shandong, Shanxi, Hunan, Jiangxi and Hainan provinces. With the deepening of the overall market, Lai Shenglong, which has been focusing on technology and product innovation, believes that it will develop plant protection drones that are more suitable for agricultural production needs!
