Design, Modeling and structural Analysis of small scale Mechanically driven crop harvesting and threshing machine for Ethiopian Condition

摘要

This study addresses the need for a cost-effective mechanized system to which harvest and thresh cereal crops in Ethiopia, aiming to improve productivity and reduce reliance on expensive and complex machinery. The research involved a comprehensive literature review, data collection, mechanism synthesis, component design, Modeling, and Structural analysis. The 3D modeling is done using SOLIDWORK software. Also, Structural analysis was conducted using ANSYS software, ensuring the safety and reliability of the design. The proposed machine, operated by human power, demonstrated the ability to harvest and thresh crops across a one-hectare area in 5.83 hours, offering a viable alternative to traditional methods. The findings suggest that this mechanized system presents a practical solution for Ethiopian farmers, reducing labor requirements, eliminating the need for electricity or fuel, and minimizing operational costs. This innovation enhances efficiency, affordability, ease of operation, and ensures the design is safe, making it an appealing option for enhancing agricultural productivity in the country.
