Description
Technical field
The present invention relates to a kind of anti-back suction jet integrated apparatus of water control, it is particularly suited for being used during underground coal mine high-pressure hydraulic slot coal seam is anti-reflection.
Background technology
The current high-pressure hydraulic cutting anti-reflection technology in coal seam is widely applied on colliery, and cutting nozzles diameter is generally 1.5mm ~ 3.5mm, is found during a large amount of uses：During dismounting drilling rod, particularly when up drilling is crept into, the water inside drilling rod is flow backwards under gravity, causes drilling rod inner space negative pressure, and the impurity in drilling can be sucked from bit part, and spray nozzle clogging is easily caused when jet slot is opened；Existing mechanical bit Integrated in rock drilling and hard coal seam in addition, integration opens effect preferably, but when creep into soft seam, because coal seam is softer, causes drill bit to be pressurized unlatching, and it is bad to cool down cutting sheet effect, causes bit damage.
The content of the invention
The present invention be directed to problems of the prior art, there is provided a kind of simple structure, with inflow control coal seam cutting jet opportunity, by anti-back suction structural defence cutting nozzles from block, safe and reliable integrated apparatus.
It includes tapered head height pressure seal drill rod, the anti-back suction ejector of water control, drill bit；Tapered head height pressure seal drill rod is linked together by the drilling rod tapered thread of front end with the anti-back suction ejector of water control, and junction is in sealing state by tapered head height pressure seal drill rod front end O-ring；The anti-back suction ejector of water control is connected by the tapered thread of front end with drill bit.
Front end is provided with conical head at tapered head height pressure seal drill rod mounting O-shaped rings.
The anti-back suction ejector of water control it include jet body, seal head, compression spring, pre-compressed spring, carboloy nozzle, O-ring 1, O-ring 2, sealed base, guiding screw pole；On jet body along the circumferential direction on be connected through a screw thread and be evenly equipped with three guiding screw poles, three track runners are evenly equipped with seal head circumference, guiding screw pole bottom is installed to inside the track runner of seal head, sealed base is installed on inside jet body, and individual event sealing is carried out by O-ring 2, sealed base front end is separately installed with pre-compressed spring and compression spring, and carries out precompressed by seal head, carboloy nozzle is welded on jet body, and O-ring 1 is installed in the O-ring groove with jet body front end.
Seal head front end is provided with tapered head, and rear end sets fluted, and recessed circumferential has carried out chamfering.
The tapered head of seal head front end when to a certain degree is reached by hydraulic impact to coordinate with sealed base, produce sealing function.
The chamfering on seal head rearmost flute periphery coordinates with the tapered head of tapered head height pressure seal drill rod front end, produces sealing function.
Drill bit is in the market all-purpose bit.
The present apparatus is installed on mining underground drill rig and uses, and according to drilling depth, increases tapered head height pressure seal drill rod（1）Quantity, from beginning to end by drilling rod tapered thread be connected.
Beneficial effect：The present invention is provided with the anti-back suction ejector of water control, in normal drilling, according to row's powder requirement corresponding water of supply, when needing to carry out coal seam jet cutting, it is only necessary to increase water, seal head is closed using the impulsive force and back pressure of water, it is to be capable of achieving high-pressure jet cutting to form pressure seal chamber, seal head is closed using water control, the free switching of jet cutting and drilling row's powder in the case of the various resistances such as soft, hard coal seam, can be realized.
Due to being provided with pre-compressed spring, in dismounting drilling rod, seal head in the anti-back suction ejector of water control is coordinated by the tapered head with tapered head height pressure seal drill rod, form annular seal space, can effectively prevent because negative pressure sucks impurity at drill bit and carboloy nozzle, when repressurization carries out causing spray nozzle clogging when jet cuts.
The drill bit of the anti-back suction ejector front end of water control can use all-purpose bit.
