Abstract Nursery pot making machine transmission system on the market are more complex, expensive, by research and optimization, coming up with a new design, and effectively improving the performance and productivity of nursery pot making machine.New programme design to the dimensions of the inpidual executive body from the transmission system design and strength check, strictly follows the modern design specification,and analysis and calculation are detailed and accurate. Making most use of bolts and other standard parts in order to short design cycles and reduce manufacturing costs,this paper focuses on the three aspects which contains the technology programs and gear, movement and power design and structural design, so as to make detailed design of the new machine,then drawing out part of the component graphs and assembly diagram.Last draw out vital parts of three dimensional solid modeling and motion simulation of the transmission mechanism. New nursery pot making machine has good performance, and power requirements are not high; it is easy to carry, suitable for widespread use throughout the country. As important measures to facilitate the cultivation of seedlings and raising seedling quality, reasonable design and widely used nursery pot making machine on practical agricultural production is of great realistic significance.

Keywords:nursery pot making machine; three dimensional solid modeling; motion simulation
