Description

Aviation spray plant protection anti-dumping medicine box

Technical field

The invention belongs to the technical field of agricultural machinery, and relates to an aviation spray plant protection anti-dumping medicine box, which is mainly applied to aviation spray plant protection.

Background technique

The agricultural aviation spray technology is an operation technology that uses the aircraft and its onboard equipment to apply the spray to the target area. The aircraft's aeronautical altitude, the tilting of the liquid, the meteorological conditions, and the atomization performance of the working equipment are all applied to the spray effect. Has a big impact. The technology has been carried out earlier in foreign countries and is applied more maturely. In 1911, the Germans first proposed the use of aircraft to spray chemicals to control forest pests. In 1918, the United States succeeded in combating pasture pests with biplane sprays. In 1922, the modified type of JN-6 military aircraft was used to spray cotton. The Soviet Union used the aircraft to spray pesticides to extinguish the mites. After the Second World War, various insecticides, fungicides and herbicides were widely available, requiring high-efficiency spray equipment to meet the needs of plant protection work, while a large number of military aircraft and pilots turned to agriculture, prompting agricultural aviation to rapidly development of. In 1949, the United States began to develop agricultural aircraft dedicated to agriculture. In the 1950s, it began to design and manufacture multi-purpose agricultural aircraft. In the late 1950s, helicopters also joined the ranks of agricultural aviation. It is currently the most developed country in the world for applying aviation spray technology. The most mature country. In addition to aircraft seeding, fertilization, and pesticide application, agricultural aviation operations include artificial rainfall, forest fire fighting, air cleaning, and killing of germs.

Aviation spray is the earliest aircraft operation project and main operation mode in China. Compared with ground spray operation, it has the characteristics of fast, high efficiency, flexibility and strong assault. It shows in the field of aviation plant protection, aviation fertilization and sanitation and epidemic prevention. The role of substitution. In recent years, China's annual use of aviation spray to control crop diseases and insect pests covers an area of more than 700,000 hm ² , the area of grassland pests and diseases is 54-700,000 hm ² , and wheat leaf fertilization is more than 1.4 million hm ² . By the end of 2012, its flight operation time was nearly 40,000 h. It ranks third in general aviation operations, and aviation spray has made important contributions to China's agroforestry development and agricultural modernization. With the development trend and requirements of China's plant protection technology, the current agricultural aviation spray technology is changing from constant spray to low capacity and ultra low capacity, extending from single operation to comprehensive operation, from extensive operation to precise operation. The precise application technique is to carry out variable spraying during the aero spray operation by using the pesticide preparations and fertilizer dosages required in different areas (small area units) of the SSM. Implementing precise application, improving work efficiency and reducing environmental pollution are important directions for the development of aviation spray technology in the future.

Unmanned helicopters have high automation, safe operation, reduced pollution, and low operating costs. Aviation plant protection with helicopters is the main development direction of plant protection technology in the future. Research shows that aviation plant protection operations can be completed quickly and efficiently The prevention and control of pests and diseases, especially the timely and effective prevention and control of large-scale explosive pests; at the same time, it is not restricted by geographical factors, regardless of mountainous areas or plains, paddy fields or dry fields, especially for surface machinery such as tidal flats and swamps. The entering areas can smoothly and efficiently complete the tasks; compared with the ground machinery field operations, the aircraft operations also have the advantages of reducing operating costs, leaving no marks and damage to crops. However, it uses ultra-low-altitude flight, which is 5-7m away from the crop canopy. The obstacles around the field, such as wires, poles and trees, cause flight safety problems. On the other hand, the air spray droplet release site is higher, which has higher requirements on the flight quality of the aircraft. If the spray of the liquid in the spray operation will greatly affect the flight performance of the aircraft, the spray droplets will be sprayed. The spectrum is wide and the target is poor. Some small droplets can drift to several kilometers away, which is very likely to cause pollution.

Therefore, in the aviation spray plant protection operation, due to the steering of the aircraft or the need to maintain a certain distance from the crop canopy, the liquid medicine in the medicine box will be inclined or oscillated, affecting the stability and safety of the helicopter flight, and seriously affecting the spray. The quality and accuracy of the application. The utility model patent of CN201633924 U discloses an unmanned helicopter spraying device, which is provided with a vertical anti-vibration plate in the medicine box, and divides the inner chamber of the medicine box into a mutually connected chamber to prevent the inside of the medicine box. The medicine box vibrates with the helicopter. Although the structure described in the utility model patent can prevent the chemical solution in the medicine box from oscillating to a certain extent, it does not prevent the inclination of the liquid medicine in the medicine box well, that is, the liquid medicine tilting is not solved. The imbalance caused by the aircraft.
