Design And Development of Five- Bar Linkage Mechanism for Automated Vegetable Transplanter

This research paper represents the design and development of a Translating Five-Bar linkage mechanism for an automatic vegetable transplanter, aimed at enhancing the efficiency and precision of agricultural transplantation processes. The Traditional transplanting of seeds is Time consuming, Labour intensive and costly activity which provides uneven plant laying and low transplanting rate. This system uses a duckbill type Five-Bar linkage mechanism which is powered by the tractor’s (PTO) Power Take-Off shaft. This driving mechanism consists of 2 crankshafts, connecting rods, and chain sprocket arrangement to achieve the best seedling placement, ensuring minimal soil disturbance and precise transplantation. This design includes kinematic analysis of the Five-Bar linkage to optimize the motion trajectory of the planting mechanism, focusing on uniform planting depth and linear spacing. This study includes the parts design and motion analysis, simulation and kinematic analysis through CAD modelling software. The integrated system enhances the energy efficiency of the mechanism, making it suitable for diverse field conditions and various crop varieties and the experimental results has shown that this system achieves reliable and consistent transplantation with reduced manual effort, proper plant laying and improved transplantation rate.
