Spraying device of unmanned aerial vehicle for pesticide spraying operations

Abstract

The invention discloses a spraying device of an unmanned aerial vehicle (UAV) for pesticide spraying operations. The spraying device of the UAV comprises a pesticide box, the spraying device and supporting legs which are all arranged on a UAV body, wherein the pesticide box is connected to the bottom of the UAV body; the supporting legs are fixedly arranged at four corners of the bottom of the UAVbody; the spraying device is arranged at the left end of the pesticide box; and the spraying device comprises a spraying box, a sealing plate and spraying holes. The spraying device of the UAV achieves the purpose of increasing the amount of pesticide spraying by controlling the sealing plate to move to the left to reveal most of the spraying holes without the need for decelerating the UAV so asto replace a method for increasing the amount of pesticide spraying by speed control and repeating spraying in the prior art, thereby accelerating the process of agricultural operations. When pesticides are sprayed, the pesticides are atomized in a rotating manner under the cooperation among the spraying holes, atomizing plates and a high-pressure pump, so as to increase the spraying area at one time and increase the efficiency of the pesticide spraying of the UAV, so that the spraying device of the UAV is suitable for popularization.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a spraying device for a pesticide spraying drone. Background technique [0002] Unmanned aircraft, referred to as "unmanned aerial vehicle", is an unmanned aircraft controlled by radio remote control equipment and self-contained program control device, or is completely or intermittently operated autonomously by the on-board computer. Compared with manned aircraft, Drones tend to be better suited for missions that are too "dull, dirty or dangerous". According to the application field, UAV can be divided into military and civilian. In terms of military use, UAVs are divided into reconnaissance aircraft and target aircraft. In terms of civilian use, drones + industrial applications are the real rigid needs of drones; at present, they are used in pesticide spraying in agriculture, but in actual use, drones still have the following disadvantages when spraying pesticides...

AI Technical Summary

Problems solved by technology

[0003] 1. At present, when drones spray pesticides, they often spray pesticides directly after they are sprayed into mist. The amount of pesticide spraying cannot be well changed according to actual needs. When there is a large demand for pesticides, drones often need to spray repeatedly when spraying Or slow down the spraying to increase the amount of pesticides sprayed, but this method is less efficient and slows down the process of agricultural operations;

[0004] 2. When the demand for the amount of pesticides is small, the amount of pesticides sprayed is often changed by speeding up the flying speed of the UAV, but the amount of pesticides sprayed cannot be accurately controlled when changing the speed, and it is very easy to happen under the high-speed flight of the UAV. Safety accidents may affect the efficiency of UAV operations;

[0005] 3. When spraying pesticides, drones often spray at the four corners of the drone. This spraying method will cause repeated spraying and excessive spraying, resulting in unnecessary waste
