Design of a five-bar duckbill-type mechanism for sorghum transplanting

Sorghum seedling transplanting is an essential agricultural activity in Sub-Saharan Africa. However, conventional manual of sorghum a time-consuming, labour-intensive, costly with low rate, uneven plant distribution, and degree accuracy. In order to realize rapid precise seedlings transplanting, duckbill-type mechanism has been designed. This five-bar linkage consisting two crankshafts, connecting rods, duckbillshaped planter improve the quality operations. The study includes kinematic synthesis analysis through MATLAB software, parts design, motion using SolidWorks software. After genetic algorithm, optimal length between cranks 300 mm, upper crankshaft 106 rod I 169 II 222 lower 67 mm. Furthermore, speed acceleration show that are planted zero-speed operation obtain high perpendicularity qualification. results proposed planting meets agronomic requirements transplanted good rate.
