This paper briefly introduced the working principle of the seedling transplanter composed of the belt seedling feeding system and the guide tube seedling planting system, and made a more detailed analysis on the innovation point of this machine - the conveyer belt seedling seedling feeding system. The basic requirements for the introduction of bowl seedlings by the guide tube seedling planter are put forward. The calculation of the transmission ratio, the length of the conveyor belt, the feeding time and the main parameters of the seed poter on the productivity, plant spacing and uniformity And the operator’s labor intensity. The conditions for ensuring the continuity of feeding are also discussed. The application of rigid body plane motion theory to describe the fall of the seedling at the end of the conveyor belt and the positive course of the centralizer under the action of the centralizer are described. Experiments show that the feeding system is simple, reliable sub-bowl, feeding attitude is reasonable, suitable for a variety of crop seedlings
