Rapid development technique for drip irrigation emitters

摘要

This paper describes the rapid development process for emitter which is the key part in water-saving irrigation device. The design of labyrinth-channel in emitters, the generation of process-oriented structural CAD model, the building of emitter prototype and its integrative experimental model based on RP are introduced in detail. The emitter prototypes can be directly applied to irrigation experiments and production practice, and hence the rapid development of drip irrigation emitters can be realized.
