Design and Development of a Universal Threshing Machine for Commercial Applications

Abstract

This study reviews existing research on the design, construction, and performance optimization of shredding and threshing machines, with the aim of developing a comprehensive understanding of their operational characteristics and identifying opportunities for improved efficiency. A systematic methodology was adopted, incorporating theoretical machine design, computer-aided modelling, finite element analysis, and motion simulation using Autodesk Inventor and MATLAB. The findings show that the universal shredding and threshing machine performs optimally, achieving an efficiency of approximately 90%, with both shredding and threshing operations executed effectively. Finite element analysis further confirms the structural suitability of the frame and cutting blades, indicating an absence of plastic deformation or failure under operational loads. Motion analysis reveals that the main shaft and tray function proportionally and maintain consistent speeds, with a linear tray velocity of about 48 m/s and an angular shaft speed of approximately 120 rad/s, validating the machine’s stable performance characteristics. Based on these outcomes, the study recommends upgrading the electric motor to improve operational efficiency, increasing blade thickness to enhance cutting performance and durability, and incorporating AnyLogic simulation software for more advanced validation of component motion and speed. The insights provided contribute to improved understanding and further optimization of shredding and threshing machine performance for industrial applications.
