Between transition joint and nozzle by the way of being screwed connection；
The water supply connector 103, which is coaxially arranged with, is provided with main intake tunnel 100, and there are four sides for the water supply connector setting
To channel 101 is adjusted, the direction adjusts channel 103 and is evenly arranged along the circumferencial direction of main intake tunnel 100；Certainly, intermediate
Connector is additionally provided with water stream channel；
There are four limiting groove 106, four limiting grooves are same for setting on the spherical surface of the water outlet of the water supply connector 103
Circumferencial direction along the section of water supply connector is evenly arranged, and the direction adjusts channel 101 and is connected to limiting groove 106, described
The side wall of the spherical groove of transition joint is provided with four direction and adjusts apopore 111, and the direction adjusts apopore 111 and limit
Position groove 106 corresponds, and the rotation connection component is set to limiting groove and direction and adjusts in apopore, wherein lead into
Aquaporin and direction adjust channel and input high pressure water, as shown in figure 3, high pressure water is provided by high-pressure pump 9, in actual condition
In, in order to provide high pressure water to drilling apparatus, it is additionally provided with following equipment, the master for high-pressure pump to be connected to main intake tunnel
Pipeline 2, the bye-pass 3 for direction adjusting channel to be connected to high-pressure pump, the equipment such as pipe conveyor 6, bracket 7 and coiling pipe bender 8,
These equipment belong to the prior art, and in Fig. 3,4 for drilling main aperture, 5 be pencil hole, by above structure, high pressure water into
Enter and then drilled by the spouting realization of nozzle to main intake tunnel, by transition joint, in order to carry out small curvature drilling, is passed through
Channel is adjusted to direction and inputs high pressure water, then into limiting groove, direction adjusting apopore ejection is crossed, since high pressure water sprays
Afterwards, can be to opposite with a water discharging direction active force be generated, which makes between transition joint and water supply connector
Relative motion is generated, makes transition joint that nozzle be driven to rotate a certain angle, to realize small curvature turning drilling；Nozzle rotation
After the completion of direction is adjusted, then stops adjusting channel water supply to direction, adjust channel to direction again when needing to adjust again and supply water, no
Same direction then adjusts channel to different directions and supplies water；In said structure, pass through waterpower driving direction adjustable spray head
It is rotated, without drilling rod and leads ramp, to adjust the pore-forming gradient in pencil hole, realize small curvature turning turning radius
Radial pencil hole is constructed, and can be avoided leading in drilling process tiltedly with deflecting operation, can be adjusted automatically according to practice of construction situation
Section drilling gradient improves the pore-forming efficiency in pencil hole, and whole device knot to greatly reduce the pore-forming process in pencil hole
Structure is simple, and manufacturing cost and use cost are cheap.
In the present embodiment, the rotation connection component includes spring 112 and roller ball 113, and one end of the spring 112 is solid
Surely be set to direction adjust apopore, the other end resist roller ball and to roller ball apply pretightning force make roller ball be partially submerged into
In limiting groove；The roller ball 113 is diametrically disposed through-hole 115, in order to which spring is fixed, the direction tune
Section apopore be step pore structure, and the bore of the water outlet of stepped hole be less than water inlet end bore, and the diameter of roller ball with
The diameter that direction adjusts the water inlet of apopore is equal, and roller ball is partially submerged into and adjusts the water inlet end of water outlet in direction, from
And guarantee the rolling planning of roller ball, and then guarantee on the one hand the stability of total can be realized by above structure
Connection between water supply connector and transition joint, on the other hand, it can be ensured that transition joint rotates relative to water supply connector,
The through-hole of steel ball can guarantee water flow proper flow.
In the present embodiment, the central bottom of the limiting groove 106 is provided with lock groove 114, in this limiting groove
In structure, the bottom of limiting groove is convex globoidal structure, and the size of limiting groove is greater than the diameter of roller ball, convex globoidal and water inlet
The spherical surface of connector is parallel, by above structure, on the one hand guarantees that roller ball can rotate in limiting groove, limiting groove is to whole
The maximum rotation curvature of a transition joint, which is realized, to be limited, and the effect of lock groove for keep transition joint, water supply connector and
The axis in the channel of nozzle point-blank, thus realize straight line creep into, in practice of construction, the rotation curvature of transition joint
Control is realized by the size of hydraulic pressure；In order to guarantee that the water flow that direction is adjusted only adjusts water outlet by direction, connect in water inlet
Multiple sealing rings 105 are provided between the water outlet end face and spherical groove of head, by the water supply connector of limiting groove position
Clearance seal between transition joint, so that it is guaranteed that the sensitivity that sensitivity and rotation curvature that rotation direction is adjusted are adjusted
With accuracy.

109 and straight hole 110, the osculum end of the bellmouth is connect with straight hole, between the hole wall of the taper and the axis of bellmouth
Angle is 20 °, and the length ratio of the bellmouth and straight hole is 2:1, in waterpower drilling, needs high hydraulic pressure that can realize brill
Into otherwise water flow cannot break through coal seam, by above structure, when the hole for water spraying of high pressure water flow Channels, due to bellmouth
It carries out water flow and collects in acceleration, to further promote hydraulic pressure and water velocity, guarantee that whole device can smoothly break through coal
Layer, and under the parameter of bellmouth and straight hole among the above, drilling effect is more preferably.
In the present embodiment, water supply connector setting there are four structure it is identical from into jet stream duct 104 (due to diagram side
To reason, should be represented by dashed line from be adopted into jet stream duct 104), it is described from into jet stream duct by the outside of water supply connector and it is main into
Aquaporin connection, described to be obliquely installed from into jet stream duct by water inlet direction to water discharging direction, the axis from into jet stream duct
Angle between line and the axis of main intake tunnel is greater than 45 ° and less than 90 °, and optimum tilt angle is 60 °, although creeping into
Cheng Zhong breaks through coal seam by the water flow that nozzle sprays, and still, the traveling of whole device is then completed by above structure, due to high pressure
Water flow passes through to be sprayed from into jet stream duct, under the reaction force of the water spray water flow, is transported to same entire drilling apparatus to drilling direction
It is dynamic, it is too small from the inclination angle into jet stream duct, then progradation can not be had, the water flow sprayed can be made to be in expansion if excessive
Hole working condition, and do not have progradation.
Finally, it is stated that the above examples are only used to illustrate the technical scheme of the present invention and are not limiting, although referring to compared with
Good embodiment describes the invention in detail, those skilled in the art should understand that, it can be to skill of the invention
Art scheme is modified or replaced equivalently, and without departing from the objective and range of technical solution of the present invention, should all be covered at this
In the scope of the claims of invention.
