Dynamic Modeling and Analysis of Seven-Bar Seedling Planting Mechanism of Transplanting Machine

Abstract:

Seven-bar seedling planting mechanism is one kind of developed transplanting mechanism of vegetable seedling transplanting machines. Dynamic equations of the link rods were established and analysis program was compiled so as to analyze the dynamic characteristics of the mechanism; Meanwhile, simulation model of the mechanism was established and corresponding virtual dynamic test was conducted based on Adams. The consistency between calculation results based on kinematic theory model and simulation results achieved from Adams was proved through comparison, which verified the dynamics model was correct and reliable. It can be concluded that the dynamic model was the basis of dynamic parameter optimization model of seven-bar seedling planting mechanism, which facilitates the parameter optimization process of the kind of seedling planting mechanism with various specifications, and it also avoided the tedious process of repeated modeling based on Adams dynamics optimization. With the analysis results of the seven-bar seedlings planting mechanism based on the established kinematic model, it was found out that the force fluctuation at the chassis caused by the reciprocating motion of the mechanism was large, which could cause machine vibration and increase the labor intensity of operators.
