Description:TECHNICAL FIELD
[001] The present disclosure generally relates to the field of UAV (Unmanned Aerial Vehicle) technology. More particularly, the present disclosure relates to the unmanned aerial vehicle with pivoting joints for spraying agrochemicals.

BACKGROUND
[002] The utilization of Unmanned Aerial Vehicles (UAVs) equipped with spraying mechanisms has become integral in modern agriculture and various industrial applications. These UAVs play a crucial role in ensuring efficient and precise distribution of liquids, such as pesticides, fertilizers, or disinfectants. However, the current designs of spraying drones encounter several challenges that significantly impact their overall effectiveness, reliability, and maintenance costs.

[003] One of the critical issues faced by existing spraying drones is the vulnerability of their nozzle tips. During non-operational phases, the protruding nozzles are susceptible to damage, leading to increased maintenance costs and the need for frequent replacement of damaged nozzle components. This issue directly affects the efficiency of the spraying process.

[004] Additionally, the orientation of spraying nozzles in conventional UAVs is often undetermined, resulting in inefficiencies in the spraying pattern. The lack of a standardized orientation leads to suboptimal coverage of the target area, diminishing the overall effectiveness of the spraying operation.

[005] UAVs with downward-folding arms encounter challenges related to the free movement of these folding arms. During handling, transportation, or deployment, the folding arms may inadvertently hit surrounding structures, causing damage to the nozzle bars and adjacent components. This not only affects the functionality of the spraying drone but also contributes to increased service and maintenance costs. Current solutions available in the market inadequately address these critical issues. The absence of a protective mechanism for nozzle tips, coupled with undetermined nozzle orientations and potential structural damage, hampers the overall efficiency and reliability of spraying drones.

[006] In light of these challenges and limitations, there exists a pressing need for an innovative solution that ensures the protection of nozzle tips during non-operational phases, establishes a standardized and optimized orientation for spraying nozzles, and prevents structural damage caused by downward-folding arms.
