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

Aim: ing at the problems of low fertilization efficiency, mostly single process operation and inconsistent fertilization depth of domestic tea garden fertilizing machine, a single spiral fixed depth ditching and fertilizing machine was designed. The machine can complete the integrated operation of ditching, fertilization and covering soil at one time through the operation mode of single spiral ditching and fertilization. The theoretical analysis and structure design of its key core components are carried out. The depth of fertilization can be consistent through the established depth control system. The performance test shows that the single spiral ditching and fertilizing machine has a maximum stability coefficient of 96.17% and a minimum of 94.29% in terms of trenching depth, and a maximum of 94.23% and a minimum of 93.58% in terms of fertilization uniformity, meeting the requirements of tea plantation production.
