Item Design of Mini Combined Harvester(JPE: Journal of Production Engineering, 2017) Abdulkarim, K. O.; Abdulrahman, K. O.; Ahmed, I. I.; Abdulkareem, S.; Adebisi, J. A.; Harmanto, D.In this research, various problems associated with harvesting of agricultural food grains by local farmers in Nigeria were identified. The aim of the research was to design low cost multipurpose mini combined harvester for production using locally available materials at affordable cost. The research was to ensure improved performance and low cost maintenance of harvester for use by farmers in developing nations. The modelling of the chassis and other components of the combined harvester was done using Solid works 2014. The selection of materials for the design was achieved using Cambridge Engineering Selector (CES) 2014. Calculations for the design of each components and power requirements to determine the engine specifications were carried out to ensure optimal performance. The output of the research was the development of mini combine harvester which is a microcosm of large capital intensive harvester, at affordable cost to small scale farmer in developing nations. The research ensures the use of mechanised farming equipments designed and developed from local materials for effective harvesting and transportation of agricultural produce.Item Finite Element Analysis of Mini Combined Harvester Chassis and Hitch(JPE: Journal of Production Engineering, 2017) Abdulkarim, K. O.; Abdulrahman, K. O.; Ahmed, I. I.; Abdulkareem, S.; Adebisi, J. A.; Harmanto, D.The perennial problems associated with harvesting of agricultural products in sub-Sahara Africa are not unconnected with financial limitations of the farmers. The design of low cost mini combine harvester was aimed at ameliorating the challenges of agricultural products harvest in Nigeria. The work presented here was a detailed analysis of low cost mini combine harvester chassis and hitch. The need for cost effectiveness, affordability, durability and efficiency of the designs necessitated detail analysis of the design to achieve the above objectives. Solidworks Finite Element Analysis (FEA) software was employed in carrying out both static and fatigue analysis of a low-cost mini combine harvester chassis and hitch design. The results were compared and contrasted, with appreciable improvements on available existing data. The stresses, displacements and strains on the chassis were significantly low with factors of safety of 2.48 and 2.80 for chassis and hitch respectively.
