摘　　要：悬臂式掘进机截割头在破岩落煤过程中产生的粉尘是一个亟需重视的安全与健康隐患。喷雾技术作为降尘抑尘的有效方法之一,内喷雾和外喷雾具有各自的优缺点。分别对纵轴式截割头和横轴式截割头内喷雾技术和结构进行了阐述和介绍。纵轴式截割头内喷雾是经内置水孔进入密闭水腔,通过截割头体表面多个均匀分布的水孔,并经过线性喷嘴喷出至截割头截齿齿尖处。横轴式截割头内喷雾由截割头、截割减速器、格莱圈形成密封水腔,通过内置水槽的配水管路流至均匀分布的喷嘴座,再由线性喷嘴喷出水雾覆盖到截齿上。为纵轴式截割头和横轴式截割头内喷雾的研发和设计提供了一种思路和参考,具有一定的实用和推广价值。The dust generated by the cutting head of the cantilever roadheader during the process of rock breaking and coal falling is a safety and health hazard that urgently needs attention.As one of the effective methods of dust suppression,spray technology has advantages and disadvantages of internal spray and external spray.The internal spray technology and structure of vertical axis and horizontal axis cutting heads were described and introduced respectively.The internal spray of the vertical axis cutting head enters the sealed water chamber through the built-in water holes,passes through a plurality of evenly distributed water holes on the surface of the cutting head body,and sprays out to the tip of the cutting head pick through the linear nozzle.The internal spray of the horizontal axis cutting head forms a sealed water chamber from the cutting head,cutting reducer and gland ring,flows through the water distribution pipeline of the built-in water tank to the uniformly distributed nozzle seat,and then sprays water mist from the linear nozzle to cover the cutting teeth.Provides a way of thinking and reference for the research,development and design of internal spray of vertical axis and horizontal axis cutting heads,and has certain practical and promotional value.
