Pipe, and connected respectively with two hydraulic push rods, one end of two flexible pipes is connected with hollow tube respectively, and multiple branch pipes are uniform soft
Pipe connects, and is placed in respectively by retainer ring on the mounting hole on arc installing plate, one end of multiple fog-spray nozzles correspond to respectively and
Multiple branch pipe connections, and passed from arc installing plate in corresponding mounting hole, one end of feed tube is placed in the middle part of hollow tube,
And be connected with hollow tube, connecting tube is connected with the other end of feed tube.
In use, first connecting hydraulic push rod with the hydraulic means of outside, the water pipe of outside is connected with connecting tube, when
When needing the depositing dust to work, outside hydraulic means promotes hydraulic push rod movement, and then hydraulic push rod is promoted moving sleeve
Slided on driving cantilever, the fixed ear on moving sleeve drives two arc installing plates to move by rotary shaft, so as to two
Arc installing plate is gradually opened in the both sides of driving cantilever respectively, the design of the support bar, can make two support bar difference
Follow two arc installing plates to move by support shaft, play position-limiting action, meanwhile, water is entered in feed tube by connecting tube,
Then being flowed into by hollow tube in two flexible pipes, the water in two flexible pipes is correspondingly flowed into multiple fog-spray nozzles by multiple branch pipes,
Then sprayed out of fog-spray nozzle, two arc installing plates are opened in the both sides of driving cantilever, and the water smoke of ejection can be in coal cutting roller
Surrounding forms water curtain, the design of the arc installing plate, can realize fog-spray nozzle and the water curtain of coal-winning machine coal cutting roller is surrounded
Circle, so as to carry out atomizing de-dusting to coal-winning machine dirt source, reach the purpose for improving dust-laying effect.
Beneficial effect.
