Jetting structure for last messenger of belt conveyor

The utility model discloses a jetting structure for last messenger of belt conveyor, it includes the conveyer, it is parallelly connected with the conveyer belt clamp in the centre that this structureis two jetting pipes, head hopper wall is stretched out to two parallelly connected one end of jetting pipe, exerted one end links together with three -way elbow through inner tube spiral ferrule, the welding having the transition pipe to constitute a gas transmission pipeline on last another connecting hole of three -way elbow, install the inner pipe threaded solenoid valve on the transition pipe and link to each other with high pressurized air source through the movable joint, head hopper wall and steel sheet welded fastening are worn out to the other end of two jetting pipes, seal throughsealed glue all around, it is fixed that the steel sheet passes through the support, processing is gone up to the jetting pipe has the orifice. The hole that head hopper wall goes up processing has the jetting pipe to stretch out is connected through self -tapping screw. This technical scheme passes through gas transmission pipeline and carries in the gas injection device, by the spout blowout onthe upper and lower jetting pipe, form height high pressure draught, blows down the adhesion at the whitewashed material of the upper and lower face of conveyer belt, and simple structure, control issimple, reduces material transportation safety manufacturing cost.
