Detailed description of the invention
With specific embodiment, the present invention is described in further details below, but the present invention is not only confined to following specific embodiment.
Embodiment
As shown in Figure 1-2, a kind of centrifugal water spray drill bit, comprises the drill body being provided with apex point end and installation end; The apex point end of described drill body is provided with hole for water spraying 1, and installation end sidewall is provided with a centrifugal water supply installation 2; The delivery outlet of described centrifugal water supply installation 2 is communicated with hole for water spraying 1 along the axially extended water cavity of drill body by one;
Described centrifugal water supply installation 2 comprises a socket and is fixed on shell on drill body installation end, the geometry of described shell be a right-angled trapezium with coplanar with it and with its parallel straight line of going to the bottom rotary body that is rotating shaft, described enclosure has toroidal cavity, a pair water pressurizing device 3 that to be arranged with the rotating shaft of drill body in described toroidal cavity be symmetry axis, the thread plug 4 that the upper side of described shell is provided with water filling port and matches with water filling port;
Be provided with the column water cavity 3.1 that an axis extends along the radial direction of described centrifugal water supply installation 2 in described water pressurizing device 3, be provided with one in described column water cavity 3.1 near the metallic piston 3.2 of drill body; Described metallic piston 3.2 is connected with the inner end of described column water cavity 3.1 by an extension spring 3.3;
Described water pressurizing device 3 outer end sidewall is provided with the input port 3.4 be communicated with described toroidal cavity;
The inner face of described column water cavity 3.1 is provided with the first water inlet 3.5 be communicated with input port 3.4 by pipeline, the first delivery port 3.6 be communicated with the delivery outlet of described centrifugal water supply installation 2 by pipeline;
The outer face of described column water cavity 3.1 is provided with the second water inlet 3.7 be communicated with input port 3.4 by pipeline, the second delivery port 3.8 be communicated with the delivery outlet of described centrifugal water supply installation 2 by pipeline;
Be provided with in described first water inlet 3.5 and the second water inlet 3.7 and only allow current to flow into the check valve of described column water cavity 3.1; Be provided with in described first delivery port 3.6 and the second delivery port 3.8 and only allow current to flow out the check valve of described column water cavity 3.1.
Described water pressurizing device 3 lateral wall contacts with the bottom surface of described toroidal cavity.
The bottom outside wall of toroidal cavity is pressed close in described input port 3.4.
Described extension spring 3.3 drift is less than 1/5th of described column water cavity 3.1 length.
The work of described extension spring 3.3 allows length to be greater than described column water cavity 3.1 length.
Described metallic piston 3.2 perisporium is provided with rubber seal.
The present invention operationally, first fills water by the water filling port on shell and screws on thread plug 4 in toroidal cavity; When drill bit starts to accelerate to rotate, due to the effect of centrifugal force, metallic piston 3.2 can to the outer end motion of column water cavity 3.1, the first water inlet 3.5 is caused to be absorbed water from toroidal cavity by input port 3.4, second delivery port 3.8 exports current make current pass through to spray along the axially extended water cavity of drill body from hole for water spraying 1 to the delivery outlet of described centrifugal water supply installation 2, and the first delivery port 3.6, second water inlet 3.7 is in closure state due to the effect of check valve; When drill bit is rotated in deceleration, due to the effect of extension spring 3.3, metallic piston 3.2 can to end motion in column water cavity 3.1, the second water inlet 3.7 is caused to be absorbed water from toroidal cavity by input port 3.4, first delivery port 3.6 exports current make current pass through to spray along the axially extended water cavity of drill body from hole for water spraying 1 to the delivery outlet of described centrifugal water supply installation 2, and now the first water inlet 3.5, second delivery port 3.8 is in closure state due to the effect of check valve.Therefore no matter drill bit is in acceleration or deceleration process, all has current to spray from hole for water spraying 1, also prevent the blocking of hole for water spraying 1 while effective water-spraying control drill bit; While shell mechanism of the present invention can increase toroidal cavity water-holding quantity simultaneously, when bit, water can converge in bottom toroidal cavity, effectively ensures the water suction work of water pressurizing device 3.
Below be only that feature of the present invention implements example, scope is not constituted any limitation.The technical scheme that all employings exchange on an equal basis or equivalence is replaced and formed, all drops within rights protection scope of the present invention.
