摘　　要：某型路面冷再生机的原有喷洒系统无喷嘴自动清理装置,整机作业时,喷嘴易被堵塞,进而引发洒水量不足,洒水不均匀,路基质量下降,取芯困难,整机液压系统压力升高,油温升高等一系列问题。针对上述问题,设计了喷嘴自动清理装置,利用气用电磁换向阀和压力气体控制气缸活塞运动,实现喷嘴自动清理功能。介绍喷嘴自动清理装置的结构组成和工作原理。实践证明,应用该装置,可有效解决喷嘴易堵塞和清理工作繁琐等问题。Water sprinkler's self-cleaning in a cold pavement recycler.A plugged water sprinkler had caused serious troubles which were hard to remedy for the core was in a hidden position.Therefore,a new sprinkler with self cleaning function was redesigned where an electromagnetic reversing valve and an air pressure control cylinder was used to control movement of the rod,thus realizing a self cleaning of the sprinkler.The text goes further to introduce how the new sprinkler is constructed and works as a fail save part.
