Plant protection unmanned aerial vehicle automatic pesticide filling system

Abstract

The invention discloses a plant protection unmanned aerial vehicle automatic pesticide filling system. The automatic pesticide filling system comprises a base, a platform used for parking the unmannedaerial vehicle, a pesticide injection assembly which is arranged on the base and used for filling liquid pesticide and a charging device. The automatic pesticide filling system also comprises a conveying device and a self-closing type barrel cover, wherein the conveying device is arranged on the base and is used for driving the platform to move close to or far away from the pesticide injection assembly, and the self-closing type barrel cover is arranged on the upper portion of the pesticide barrel; the liquid injection assembly comprises a liquid guide pipe, a liquid injection pipe which is connected with the liquid guide pipe, a cantilever beam and an electric water valve, wherein the cantilever beam is connected with the base in the single-degree-of-freedom sliding connection and used for supporting the liquid injection pipe, and the electric water valve is used for controlling the liquid injection of the liquid injection pipe; the platform comprises a bearing platform for bearing the unmanned aerial vehicle, a weighing element and a positioning device, wherein the weighing element is arranged on the bearing platform and is used for weighing the liquid in the pesticide barrel and the positioning device is used for limiting the unmanned aerial vehicle. According to the unmanned aerial vehicle, electric energy and liquid pesticide can be timely supplied to the unmanned aerialvehicle, when the pesticide is added, the pesticide barrel changing is not needed, the whole process does not need manual participation, and time and labor are saved.

Description

technical field [0001] The invention relates to an unmanned aerial vehicle replenishment system, in particular to an automatic irrigation system for plant protection unmanned aerial vehicles. Background technique [0002] With the development of technology and information technology, plant protection drones are more used to replace manual fertilization and spraying. However, at present, the capacity of the medicine barrel of the plant protection drone is limited. During the plant protection process, the empty medicine barrel needs to be removed and the full medicine barrel should be installed on the drone. In order to meet the needs of the work, it is time-consuming and laborious to manually replace the medicine barrel frequently; , the lid of the medicine barrel needs to be opened every time the liquid medicine is added to the medicine barrel. When the medicine barrel is full, the lid of the medicine barrel can be closed. It is impossible to fill the medicine without openin...

However, at present, the capacity of the medicine barrel of the plant protection drone is limited. During the plant protection process, the empty medicine barrel needs to be removed and the full medicine barrel should be installed on the drone. In order to meet the needs of the work, it is time-consuming and laborious to manually replace the medicine barrel frequently; , the lid of the medicine barrel needs to be opened every time the liquid medicine is added to the medicine barrel. When the medicine barrel is full, the lid of the medicine barrel can be closed. It is impossible to fill the medicine without opening the lid, so its filling The filling efficiency is low; at the same time, when the medicine barrel is about to be filled, the medicinal liquid inside the medicinal barrel will splash out, causing a large amount of medicinal liquid to flow out, causing the medicinal barrel to not be completely filled and causing the initial capacity of the medicinal barrel to be filled. Fewer liquid medicines have greatly affected the efficiency of plant protection; finally, there are still two prominent problems in the existing plant protection drones: First, its power consumption is fast and the energy stored in the battery is limited, so it cannot be completed by a single machine and a single battery. Large-scale plant protection work; second, the wings or other weak components of drones are easily crushed, so their transfer is difficult
