Nozzle apopore central axis is constituted in inclined-plane nozzle carrier and the angle of spray head water-supply-pipe water (flow) direction central axis is 135
Umbrella shape water spraying structure, the utility model nozzle can generate the cleaning of residue progress more thoroughly in high pressure sector water flow device to hole.
Compared with prior art, the utility model has the advantage that as follows: the utility model spray head varying diameter portion inclined-plane
4 groups of nozzles are symmetrical arranged, the angle of every group of nozzle water outlet central axis and spray head water delivery direction central axis is 135 degree, application
When can be combined with positive cleaning sprayer construction cleaning treatment, to pore-forming cavity lower semisection bottom hole direction half length and on
Half hole mouth direction half length uses positive and negative high-pressure nozzle to be turned surely, rotated and the reciprocating flushing of rotation.Borehole cleaning spray
Head in the process of walking elapses part rock slag and sillar to the two sides of travel region, until tunneling boring oral rinses are clean；Spray
Head device is directly connect with spray tool water-supply-pipe, does not need to be individually for its setting special equipment, while the hole flushing work progress exists
Implement in hole, avoids high pressure water flow security risk during hole flushing.
