Plant protection unmanned aerial vehicle with automatic pesticide liquid proportioning device and working method thereof

Abstract

The invention discloses a plant protection unmanned aerial vehicle with an automatic pesticide liquid proportioning device. Wings are arranged on the two sides of an unmanned aerial vehicle body, a pesticide liquid tank and a water tank are arranged below the wings, blades are rotationally installed on the top of the unmanned aerial vehicle body and above the wings, and a mixing and proportioning tank is arranged on the unmanned aerial vehicle body and located between the two wings; the pesticide liquid tank and the water tank are both connected with the mixing and proportioning tank through a liquid proportioning pipeline, an electromagnetic proportioner is arranged on the liquid proportioning pipeline, a liquid guide pipe is arranged at a liquid outlet in the mixing and proportioning tank, a liquid outlet control valve is arranged on the liquid guide pipe, the liquid guide pipe is connected with the high-voltage electrostatic spraying head through a hose, and a flow meter is arranged on the hose; a telescopic support is arranged between the unmanned aerial vehicle body and the high-voltage electrostatic spraying head, and mounting supports used for mounting the high-voltage electrostatic spraying head are arranged at the positions, located at the two ends of the high-voltage electrostatic spraying head, of the telescopic support. Automatic proportioning of pesticide liquid can be achieved, waste caused by excessive dosage is avoided, and meanwhile harm to operators caused by manual dosage is avoided to the maximum extent.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a plant protection unmanned aerial vehicle with an automatic medicinal liquid proportioning device and a working method thereof. Background technique [0002] With the rapid development of my country's agriculture, agricultural pest control is still the focus of agricultural production. Spraying chemical pesticides is the main method for orchard and farmland pest control at the present stage. The high cost has now hindered the development of pest control work to a certain extent. In order to achieve rapid and effective pest control, it is urgent to use more advanced scientific pesticide application methods to replace traditional plant protection operations. It has shown obvious characteristics and advantages. [0003] At present, my country's plant protection operations require a lot of labor and labor intensity. The use of manual sprayers and knapsack motorized s...
