Study On Transplanting Mechanism Of Tobacco Block Seedling Transplanting Machine

Tobacco is an important cash crop, has many potential uses are being developed, the use in food processing and pharmaceutical raw materials. China’s tobacco acreage has reached3300mu, due to the slow development of domestic transplanting technology, China’s mechanical transplanting has been unable to carry out large scale, has seriously hampered the development of China’s tobacco industry.Most of the existing domestic transplanting mechanical imitation of foreign advanced models, and model number of the complex structure, difficult to meet the needs of our farmers for tobacco transplanting operations. For these reasons, this study analyzed the technical basis of the existing domestic and international transplant technology, combined with the needs of transplant operations in China agronomic requirements, design beak seven transplanting institutions.In this study, preliminary structural optimization based on the main stage of the transplanting process analysis, transplanting institutions displacement equation and rate equation, to build a parametric simulation mathematical model using ADAMS software on the impact parametersimulation analysis, and optimal control theory has been optimized for each parameter. Optimization of seedling transplanting machine, based on secondary general rotation design test methods, the unit forward speed, planting is buried angle, the suppression of the wheel angle for the experimental factors, seedling upright was a test indicators, duckbill-type VII rod transplanting agencies conducted a field experiment. Obtained by orthogonal experiments, the factor indicators significant level; and by regression of experimental data obtained mathematical statistical analysis, regression mathematical model was established between the factors and indicators, the optimal combination of the kinematic parameters and indicators The value of the unit forward speed of0.23m/s, and Transplanter buried angle of11°, and the suppression of the wheel angle18°. The results showed that the transplanting institution can be better to complete the transplanting operation requirements, and seedling upright rate of more than97%.
