AI Technical Summary
Existing fertilization devices cannot penetrate the soil to deliver fertilizer, resulting in low fertilizer absorption efficiency, reduced tree productivity, and inconvenient operation.
A fertilization device for forest tending was designed, comprising a variable diameter pipe, a control pipe, and a fertilization pipe, equipped with control components. Through the mechanical linkage of metal rods, gears, and toothed plates, precise control and discharge of fertilizer are achieved.
It enables precise application of fertilizer around the tree roots, improving fertilization efficiency and accuracy, reducing operational difficulty, and enhancing user experience and safety.
