Through the statistics and analysis of data of China’s rapeseed production, we can find the necessity and urgency of using rape transplanter.. Rape is a major edible oil crops, providing approximately45%of China’s national share of edible oil. China is a big country not only in rape production, but also in rape consuming. In order to upgrade the output of rape, and to reduce labor cost and labor intensity, the article proposed the urgency of the using rape transplanter.The papers tell the differences between various types of transplanters through analysis and comparison, and finally selecting a chain, clip-on transplanter. The main research work carried out as follows:1. Through calculations of traction, traction power and suspension torque, getting the carrying capacity of the rack and designed a frame, and finally50-type tractor were selected.2. Based on the demand of the plant space and line space, etc., calculated transplanter chain drive, distributed the planting device three transmission ratios, and designed the device with a guide seeding, chain clip, and a sprocket which fits regulating the transmission line space in the rows as well. Thus a simple and economical and practical Transplanter was designed.3. In order to improve work efficiency when planting, putting forward the fertilization requirements. Determining the driving program of the discharging fertilizer system.. Through calculating transmission chain device, designing out the adjustable discharging fertilizer system.4. Taking uncertain factors such as the surface roughness and soil soft into account, I design the adjustable depth-degree wheel which is not only a good solution to the soil factors, but also settling the join between wheel and rack.5. In research, through introduction of the modern designing theory and applications of the three-dimensional designing software to design3D transplanter.. Carrying out the influencing rules of rape planting when the influencing factor works, making improvements of related spare parts of the transplanter.. Planting apparatus is the key to ensure the quality of transplanting.6. Making3D models of transplanter frame, ground wheels, guided seeding device, seeding folders, transmission chain, opener and fertilizer discharging system. Besides, Assembled transplanter with two lines and four lines were also made models.7.Through experiments, from the point of view of the transplanting quality, there is a certain degree of the omission of planting rate, the main reasons for the omission is due to the proficiency of operators,the dividing of rape seedling and the speed of tractors. But the buried rate and injury rates are lower, this indicates that the quality of the machine itself is still acceptable and the transplanter works better in the sand irrigated soil which also shows a good adaptationThis analysis is valuable to the designing and using of the same type of transplanter and the it is suitable for current China’s national conditions with simple structure, low cost, and stable performance. Looking forward to working out a agriculture machinery which can be planting from culture of seeding.
