Problems solved by technology

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide an agricultural spraying drone that uses negative pressure boosting to achieve drainage, so as to solve the problem that the current plant protection drone is more suitable for crops such as wheat and rice. For vigorous plants, the spraying penetration of pesticides is not enough to enter the interior, which leads to problems such as spiders and mosquitoes under the leaves cannot be solved. The problem of greatly increased consumption

Abstract

The invention discloses an agricultural spraying UAV achieving drainage with negative-pressure pressurization. The agricultural spraying UAV comprises a pesticide adding cover, a liquid level observation port, a fuselage, a spraying device, a landing frame and a heat dissipation hole. After the spraying device is started, a forward blade and a reverse blade provide flight power. A rotating mechanism is rotated by the wind during the rotation of the forward blade, thereby rotating a spraying port. A pressurizing mechanism operates in conjunction with rotation of a drive shaft, and drives a negative-pressure mechanism to pressurize the inside of the spraying port. The agricultural spraying UAV improves the penetrating power of the spraying, enables the pesticide to enter the vigorous plantsquickly and effectively, prevents workers from spraying for the second time, and saves the pesticide dosage.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to an agricultural spraying unmanned aerial vehicle which uses negative pressure boosting to realize water drainage. Background technique [0002] There are many types of unmanned aerial vehicles and differences in fields. Compared with manned aircraft, it has the advantages of small size, low cost, and convenient use. Plant protection drones are drones in the field of agricultural and forestry plant protection operations. The main components are It consists of three parts: flight platform, navigation flight control, and spraying mechanism. If farmers have a large planting area, they can consider buying drones. The existing plant protection drones on the market have such problems in the process of spraying pesticides: [0003] The current plant protection drones are more suitable for crops such as wheat and rice. For plants that grow vigorously, the spraying penetration of pe...
