Small bowl transplanting seedlings into the onboard computer-aided analysis Abstract In the thesis, we discuss the seedling launching mechanism of a planter which are applied in transplanting of baccy、corn、beet、eggplant、tomato、cotton ...etc. According to the requirement for agronomy transplantation to grow seedlings, we have found a good method to the ones that are suitable for the baccy nutrition bowl and grow seedlings and transplant in optimization design on the foundation of analyzing numerous transplanting machines both at home and abroad, and through the investigation of the result of the homework, we have analyzed and researched the universal law of the plant shoots in machinery and found some factors that affect the result of plant shoots. The crank and rocker mechanisms are applied to the seedling launching mechanism. Because the terms is limited, in practice, the aspect treats to further enhance, examination proceeding further, analyze, then design, make a cotton for designing planter attain the good work function index sign and work dependable and reliability, but the most important must satisfy the agriculture produce of request. Based on analysis of transplanting parts movement, through development of mathematical model describing seedling moving procedure, the entity of transplanting parts were established with software Inventor, and connections of the parts were created. Simulation of planter working procedure was carried out and moving track was set up for study of planter key points in comparison with mathematical model, so the optimum parameters for transplanting parts were obtained. Key words: planter; crank and rocker mechanisms; seedling launching mechanism.
