Feeding platform and feeding method suitable for field operation feeding for agricultural unmanned aerial vehicle

Abstract

The invention discloses a feeding platform and a feeding method suitable for field operation feeding for an agricultural unmanned aerial vehicle. The feeding platform comprises a mobile rack, and a take-off and landing platform unit, a pesticide supplementing unit and an energy supplementing unit arranged on the rack; the take-off and landing platform unit comprises a landing plate and a lifting mechanism, and the lifting mechanism is arranged between the bottom of the landing plate and the rack; the pesticide supplementing unit comprises a pesticide storage box and a pesticide feed pump. According to the invention, the mobile rack is adopted to carry the feeding platform, and thus the unmanned aerial vehicle can be carried to move flexibly and conveying is facilitated; when the unmanned aerial vehicle performs operation, the take-off and landing positions of the unmanned aerial vehicle can be changed continually midway for supplementing energy and spraying materials, and the take-off and landing positions adjacent to the operation positions can be selected, so that effective operation duration of the unmanned aerial vehicle is increased, and the operation efficiency of the unmanned aerial vehicle is improved. The lower part of the landing plate is provided with the lifting mechanism, so that the landing plate not only can be maintained in a horizontal state in the uneven farmland ground, but also can be adjusted to an appropriate height.

Description

technical field [0001] The invention relates to the field of agricultural machinery equipment, in particular to a replenishment platform and a replenishment method suitable for field operations of agricultural drones. Background technique [0002] In recent years, the field of UAV operations has been extended to the agricultural field, including low-altitude farmland remote sensing, farmland spraying pesticides, etc. Because the UAV has the advantages of not needing a dedicated airport, strong maneuverability, easy maintenance, easy low-altitude and stable flight, and the ability to hover in the air, take off and land vertically, it can free farmers from heavy and dangerous operations, making unmanned The machine farmland operation method is favored by the majority of users. However, at present, pesticide spraying still mainly relies on manual assisted ground mechanical spraying, and drone pesticide spraying technology has not been widely used in practice. [0003] At this...

AI Technical Summary

Problems solved by technology

We know that UAVs have relatively high requirements for takeoff and landing sites, and need to take off and land on a certain area of ​​flat open space; however, the ground environment around farmland is uneven, and it is often difficult to find a place to take off and land that meets the requirements near the farmland.

If you forcefully take off and land on a site that does not meet the requirements for helicopter takeoff and landing, it will not only damage the crops in the field, but also cause the danger of bombing; if you take off and land far away from the farmland, multiple takeoffs and landings will not only increase the labor of operators Intensity will also shorten the effective operating time of drones
