Design and Development of Twin Blade Battery Operated Weeder

Abstract

Weeds are plants or vegetation that grow where they are not wanted, absorbing nutrients intended for cultivated crops and hindering their growth. Traditional weed control methods, such as manual weeding, are labour-intensive, expensive, and time-consuming. Chemical weeding, on the other hand, can lead to environmental pollution and health issues. Conventional engine-operated weeders are not only costly and heavy but also contribute to pollution and are impractical for inter-crop weeding due to their large size and limited manoeuverability. This project focuses on developing a lightweight, battery-powered cultivator/weeder that can be charged using solar panels. The device features oscillating twin blades designed to cultivate soil and remove small weeds lightly. Its ergonomic design reduces strain on the back and shoulders, while its narrow profile allows for operation in tight spaces. The weeder is eco-friendly, requiring no gas or oil and producing no harmful fumes. The project involves the design and kinematic linkage design, 3D solid modeling, Ansys structural analysis, fabrication, and testing of the cultivator/weeder.
