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 can the drill bit of automatic water jetting, comprise 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 axis of rotation, 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 axis of symmetry, 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 described centrifugal water supply installation 2 radial direction in described water pressurizing device 3, described column water cavity 3.1 outer face be fixed with one first ndfeb magnet, in described column water cavity 3.1, be also provided with a metallic piston 3.2; The end face of described metallic piston 3.2 is fixed with second ndfeb magnet 3.3 repelled mutually with described first ndfeb magnet;
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 one way 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 one way valve of described column water cavity 3.1.
