Abstract

In the view of low efficiency and quality and high labor intensity of Salvia miltiorrhiza tilted transplanting on mulch-film by artificial transplanting，the existing transplanter is not suitable for tilted transplanting of Salvia miltiorrhiza on mulch-film，and combining with the agronomic requirement of high efficiency production technology of Salvia miltiorrhiza big-ridge double-row on mulch-film，a duck-billed tilted transplanting mechanism for Salvia miltiorrhiza was designed based on deformed elliptical gear-double variable speed crank five-bar mechanism. On the basis of trajectory，tilted gesture of planting apparatus and design requirements which was required by transplanting mechanism，the working principle of the mechanism was analyzed and the theoretical model of mechanism was established. The visual auxiliary programs for human-computer interaction was established by using Matlab（Matrix Laboratory） dependeding on the theoretical model. With the help of auxiliary programs，the influence rules of parameters for mechanism on tilted angle and endpoint motion trajectory of planting apparatus were studied，the human-computer interactive method was used to get the parameters combination suited for agronomic requirements tilted transplanting mechanism on mulch-film of Salvia miltiorrhiza. According to the optimized parameters combination，the prototype was designed for virtual simulation and prototype field experiment. Prototype experiment showed that the deformed elliptical gear-double variable speed crank five-bar tilted transplanting mechanism of Salvia miltiorrhiza on mulch-film could meet the agronomic requirements of Salvia miltiorrhiza tilted transplanting on mulch-film while ensured the quality of operation，the seedling angle qualification rate was 90.7%，the leakage rate was 2.7%，the plant spacing variation coefficient was 5.6%，and the planting depth qualified rate was 93.7%.


Keywords: Salvia miltiorrhiza, tilted transplanting on mulch-film, double variable-speed crank five-bar linkage, parameter optimization
