AI Technical Summary
Existing unmanned plant protection robots suffer from problems such as uneven application of pesticides, path deviation, missed spraying or repeated spraying in complex terrain conditions. They are also unable to adapt to changes in crop growth stages and density, which affects the effectiveness of operations.
An unmanned plant protection robot was designed, which adopts three sets of adjustment mechanisms inside the protective cover, including a height adjustment component and an angle adjustment component. Combined with a telescopic rod, a nozzle mounting hole and a guide plate, and through the cooperation of slide rails, a rotating interface and track wheels and gear sets, the spraying height and angle can be flexibly adjusted, thereby enhancing environmental adaptability and positioning accuracy.
It improves the uniformity of pesticide application and operational stability, avoids missed spraying or repeated spraying, enhances the equipment's ability to pass through complex terrain and its operational stability, and ensures accurate coverage of the spraying range.
