AI Technical Summary
Existing drones for planting on slopes are prone to clogging of the discharge port due to caking during fertilizer application, resulting in uneven application. Furthermore, fertilizer particles tend to stick to the equipment surface, causing corrosion. The lack of effective anti-adhesion and slow-descent designs leads to insufficient stability.
The design includes a spreading component and a stopping component. The spreading component uses a rotating rod and spiral blades to achieve uniform fertilizer transfer. The stopping component uses a motor-driven running rod and push plate to adjust the position of the stopping rod to prevent fertilizer from sticking, and a spring damper to achieve slow descent.
It effectively prevents clogging of the discharge port, ensures uniform spreading, reduces fertilizer adhesion, improves equipment cleanliness and stability, and enhances operational convenience and safety.

First, since the fertilizer is concentratedly stored in the box body, the discharge port is prone to be blocked due to fertilizer caking or poor flowability, resulting in uneven spreading or even unmanned plane shutdown, which affects operation efficiency and fertilization effect. Secondly, during the fertilizer spreading process, due to the influence of air flow, part of the fine particles is prone to be scattered and adhered to the surface of the metal components such as landing rod of the unmanned plane, which is not only difficult to clean after long-term use, but also may corrode the equipment structure, increasing the maintenance cost. In addition, due to the lack of effective anti-adhesion and slow descent mechanism, the stability of the unmanned plane is insufficient when landing on the slope, which further affects its applicability and operation convenience in complex terrain.
