Projeto de um dispositivo hidráulico para rachar lenha

Abstract

This final course project aims to develop a hydraulic device attachable to tractors, designed for the wood-splitting process, a common activity in rural areas. The project's goal is to replace the manual method, traditionally carried out with chainsaws, with a safer, more efficient, and less physically demanding system. The device uses the force of a hydraulic cylinder to push the wood against a wedge, splitting it in an automated and less labor-intensive manner. The project was conceived with a focus on optimizing ergonomics, reducing occupational risks, and increasing productivity. Detailed structural analyses were performed using simulation software to ensure the equipment's integrity and durability. The choice of materials, such as ASTM A36 steel for the structure and SAE 1045 steel for the wedge, was based on the mechanical requirements and performance needed for the device's efficient operation. The results show that the device is capable of splitting wood quickly and safely, and is easy to transport and attach to tractors, expanding its application in the field. The technical validation of the project was confirmed through force calculations and simulations, proving its feasibility and achieving the proposed objectives. This work significantly contributes to the modernization of agricultural practices, offering an innovative solution for the wood industry.
