Abstract： In order to improve the design efficiency of the hole seeding transplanting machine，the modular design of the transplanting machine was developed based on the thought of modular function division. Through the analysis of the structure characteristics of clamping claw parts，the modular database of institutions parts were established by referring to the example of the key part of clamping claw design. Aiming at the problem of realizing the query and call of modular material，an application software platform for database was established. Through setting up software platform between the design platform and material database，problems of seamless link between them were solved. The clamping claw was modular designed on this software platform. The results of modeling and assembly design show that this platform has good efficiency and effectiveness，which proves a reference of modular design for other agricultural machinery.
