Design and experiments with a single spiral fixed depth ditching and fertilizing machine

Area of Science:

• Agricultural Engineering
• Agronomy

Background:

• Existing tea garden fertilizer machines suffer from low efficiency, complex operations, and inconsistent fertilization depth.
• These limitations hinder optimal nutrient application and crop yield in tea cultivation.

Purpose of the Study:

• To design and develop a novel single-spiral fixed-depth ditching and fertilizing machine for tea gardens.
• To address the inefficiencies and inconsistencies associated with conventional fertilization equipment.

Main Methods:

• Theoretical analysis and structural design of key components, including the single-spiral mechanism.
• Integration of ditching, fertilization, and soil covering into a single operational process.
• Implementation of an adjustable depth control system for precise fertilization.

Main Results:

• The designed machine successfully integrates ditching, fertilization, and soil covering.
• Performance tests demonstrated high stability in trenching depth (94.29%-96.17%) and fertilization uniformity (93.58%-94.23%).
• The machine meets the operational demands and precision requirements of tea plantations.

Conclusions:

• The single-spiral fixed-depth ditching and fertilizing machine offers a significant improvement over existing technologies.
• This innovation enhances fertilization efficiency and consistency in tea gardens.
• The developed machine is suitable for practical application in tea plantation management.
