Problems solved by technology

[0003] Existing spraying devices cannot spray plants efficiently and directionally, and the spraying process is easily disturbed by external wind, resulting in a decrease in spraying efficiency and accuracy. In addition, the existing spraying devices are all single nozzles, which cannot realize the linkage of multiple nozzles to form a contrast. area, it is impossible to compare the efficacy of various fertilizers, and the plant protection effect is poor

Abstract

The invention relates to an efficient spraying device based on an unmanned aerial vehicle technology and an operation method. The efficient spraying device comprises an unmanned aerial vehicle and spraying assemblies carried on the unmanned aerial vehicle. A medicine box is arranged at the top of the unmanned aerial vehicle, and the plurality of spraying assemblies are arranged at the top of the medicine box and distributed at intervals. Each spraying assembly comprises a fixed part, a movable part and a spray head, wherein the fixed part is fixedly installed at the top of the medicine box, the top of the fixed part is connected with the movable part in a matched manner, the movable part can rotate, the end of the movable part is connected with an air bag in a matched manner, and the position, located at the inner side of the air bag, of the end of the movable part is connected with the spray head in a matched manner; and a plurality of air holes are formed at the edge of each air bagin the circumferential direction at intervals, and the air holes spray air to form an air curtain.

Description

technical field [0001] The invention relates to the field of agricultural plant protection, in particular to an efficient spraying device and an operation method based on unmanned aerial vehicle technology. Background technique [0002] Plant protection is a very important link in agricultural production, which affects the healthy growth of crops. The methods of plant protection include chemical control, physical control and biological control. Because chemical control has the characteristics of high efficacy and timely control, it can control and Prevention and control of sudden and large-scale outbreaks of diseases and insect pests is the most widely used method of plant protection. The realization of chemical control requires plant protection sprayers. As a large agricultural country, China has 1.8 billion mu of basic farmland and requires a large number of agricultural plant protection operations every year. More than 100,000 people are poisoned by pesticides every year,...
