ABSTRACT:The development of rice transplanter should suit one's measures to local conditions according to the local population, soil quality and other factors, to find suitable for local conditions of rice transplanter. Should know the status of the use of transplanting machine at home and abroad, and to understand the structure of each part of rice transplanter, type, principle and structure, a seedling box, the transplanting mechanism, seedling feeding mechanism, a frame, running gear and bearing floating body, related data, matching power rice transplanter, development trend.

　　　This paper mainly introduces the design of sliding on the current SR2Z-2 type transplanter send chain drive box, according to the theme of the planting box chain roller chain, transverse feeding left drive housing, reed, chain box, the inner sleeve, flat washer, shaft and bearings and other parts of the design and calculation. This device can greatly improve the productivity, reduce the cost of human resources, promote the development of agricultural machinery. The design for this problem are listed in a variety of programs, taking into account the efficiency, stability and economic aspects of the problem, this scheme is more suitable for SR2Z-2 type transplanter finally, the performance of the transplanter has been further perfected.
