Design and Development of Groundnut Harvesting (Threshing) Attachment

Groundnut harvesting is a crucial aspect of farming, traditionally carried out manually by farmers. However, advancements in technology present an opportunity to develop machinery that can streamline and enhance the process. To meet this demand, a new groundnut harvesting product has been designed, taking into consideration various parameters such as customer needs, product size, mechanism type, ergonomics, spare parts availability in rural areas, and field performance.To identify the specific requirements for groundnut production, a comprehensive study was conducted, involving interviews with approximately 300 farmers. Statistical analysis and experimental data were used to make assumptions, and a Chi-square value was calculated using cattle livestock as a factor. The resulting probability values were compared to expected frequencies. After analyzing the data, it was found that the degrees of freedom and level of significance from the chi-square value table indicated α >0.05. This indicates that there is a significant correlation between the category of farmers and the availability of cattle livestock. In summary. Likert scale is used to evaluate the facilities, like labor availability, machinery and wages paid during cultivation season is analyzed. And also prepared the Product Design Specification for develop the product. Based on these findings, three concepts were generated and created in 3D virtual models. The final concept was selected using the PUGH matrix method, and the resulting product consists of a wheelbase, engine, belt and chain drives, and handles are the important parts to develop the new concept.
