Design of Agricultural Ploughing Tool

Abstract

In last few decades we all witnessed the development in each and every field. In the field of agricultural also we had seen remarkable development, big farmers are now a day's using cultivator, harvester, tractor, advance machine tools and advance farm equipment's, but in the country like India, 70% of farmers are small and marginal and they are still doing farming by traditional method. Thus they are in need of improved agricultural tools that may be hand driven or bullock driven. In this paper similar advanced type of tool is designed. Modelling and analysis of Agricultural Plough is done. The input conditions are taken based on a survey leading to understanding of the zero ground conditions. Materials and manufacturing processes are selected for manufacturing the same. Redesigned plough with HSS tip and grey cast iron body reduces replacement cost. Stress analysis shows maximum stress 140.4 MPa at bolt holes. Interference fit assembly increases tool life. The cost of the overall tool was reduced, as, in case of failure, the farmer will only have to bear the cost of replacing the tip of the tool, and not the entire tool body. The farmer receives high quality tool at low cost, as hard material is used as the tip, and its cost is less, as it has less volume. The life of the tool is increased as we have to replace only the tip of the tool.
