Description

Technical Field

[0001] The utility model relates to the technical field related to agricultural unmanned aerial vehicles, and in particular to a liquid spray mounting device for unmanned aerial vehicles. Background Art

[0002] At present, with the advancement of science and technology and the popularization of drone technology, in order to improve the spraying efficiency of pesticides in agricultural production, existing large-scale farms and forestry parks usually use drones to spray pesticides. However, most of the existing pesticide spraying drones can only fix a single pesticide bottle, and most of the existing farms and forest areas use a variety of drugs in combination when spraying pesticides. Obviously, when using existing drones to spray multiple pesticides, multiple round trips are required to install and spray each pesticide one by one, which will undoubtedly limit the spraying efficiency of pesticides. For this reason, we propose a drone liquid injection mounting device. Utility Model Content
