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, technical solution of the present invention is as follows: a kind of 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 at least one 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 outer surface of described shell is anchor ring, 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 described shell is provided with water filling port and matches with water filling port;
Be provided with the column water cavity 3.1 that is axis with the diameter 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.
Toroidal cavity lateral wall is pressed close in described input port 3.4.
