STUDY ON THE EFFICIENCY OF A STONE-COLLECTING MACHINE USING DISCRETE SIMULATION METHODS (DEM)

This study presents a digital simulation of a stone-picking machine using the Discrete Element Method (DEM) to analyze its interaction with heterogeneous soil and scattered stones. A detailed 3D model of the machine was developed in SolidWorks and imported into EDEM software to replicate the mechanical operation and material flow during field use. The simulation aims to evaluate the machine's performance in terms of stone collection efficiency, component interaction with granular material, and potential clogging scenarios. By accurately modeling the geometry and motion of key parts, such as the collection system and conveyor belt, the study provides insight into operational dynamics that are difficult to capture through physical prototypes alone. This workflow demonstrates how integrating CAD-based design with DEM simulation can contribute to optimizing agricultural machinery for improved field reliability and performance. Additionally, the stone-picking machine can be effectively used in field preparation prior to soil work for establishing vineyards and orchards, helping to create a clean and suitable seedbed that supports sustainable crop development.
