Development on Rice Plotted-Seeding Sequential Transplanter of Ejection Type

To make transmission more stable,accurate and seeding to be ejected reliably,a new sequential transplanter of cam-lever ejection type is developed according to the characteristics of rice plotted-seeding.The transplanter is composed of chassis,differential transmission system,ejection mechanism for rice plotted-seeding,convey mechanism,and seeding guiding device,which are analysed and discussed in mechanisms and working principle.the parameters of the resert spring is optimized to insure that it can return within a little time lest transmission of the seedling tray is disturbed.Convey mechanism is improved,the teat-bed is developed and experimented,and the result indicates agronomic requirements are met.
