At present， it has already been widely used for tobacco， corn, vegetables, fruit, lotus and other crops cultivation at home and abroad. Jilin yanbian technical institute developed 2ZB - 45 type (SFP),which has been made in batch production in 1990. Years of time shows crops that using mechanism port seedling cultivation methods has the following characteristics: healthy, root developed, have strong disease-resistant, drought resistance ability. And crop agriculture efficiency of a mortar yukon mechanism is good, the unit output has low cost. This system port machine is inexpensive, simple operation,and easy maintenance. The author independently design the machine mainly based on the working principle and virtual machine dynamic parameters of type of 2ZB - 45 (SFP). This paper mainly introduces the design process, design steps, design method. Using knowledge of undergraduate study stage, expounds the main processes of calculation; checking the strength and service life of main parts, finally obtained the main structure and size of machine and its main components, and provides basic data for further rendering drawings and parts graph.
