Design and development of coconut ultra-low volume climbing sprayer

Abstract

Harmful pests greatly affect the growth of coconut trees. These pests attack the outer layer of the coconut and pollute it from the inside. As a solution to this problem, tree-specific pest control devices have been developed. The coconut sprayer has been developed at Dept. of Agricultural Engineering, Kakinada Institute of Technology and Sciences. East Godavari. In the year 2022. A new technique has been developed to model the accumulation of spray on the leaves of coconut trees. Injecting the agent directly on the leaves from an optimal location dramatically reduces the amount of chemical pesticide needed. Due to the height of coconut trees, climbing injuries especially falls, are common in India. The sprayer can climb at an average speed of 3 m/min and carry a sprayer with a tank capacity of 2 Liters. The sprayer sprays at range of 45 cm with 4.5 k/g/cm2 for a 16 m tree and 36 cm with 4.5 k/g/cm2 for a 13.5 m tree when tested.
