Máquina semiautomatizada e sustentável para quebra do Coco Babaçu: uma solução tecnológica de baixo custo para redução de esforço e risco nas comunidades extrativistas

Abstract

This Final Paper presents the development of a low-cost electric machine for cracking babassu coconuts, designed as an ergonomic, safe, and sustainable alternative to the traditional manual process carried out by babassu coconut breakers. The project was based on principles of applied mechanical engineering and social technology, aiming to reduce physical effort and accident risks while increasing productivity and improving working conditions. The development included conceptual and experimental stages, evolving from early prototypes using washing machine motors and gear reduction systems to the final configuration, which employs a sliding gate motor with internal reduction, chain transmission, and a connecting rod–crank–piston system. Three-dimensional modeling was performed using Autodesk Inventor software, allowing for kinematic analysis, component sizing, and geometric validation of the assembly. The results indicate that the project meets the criteria of simplicity, low cost, and safety, demonstrating technical feasibility and strong potential for application in extractivist communities. It is concluded that the proposed machine represents an efficient social technology, capable of combining mechanical innovation, sustainability, and cultural appreciation of babassu coconut breakers.
