Embodiment
The present invention is described in further details with specific embodiment below, but the present invention is not only limited in detail below in fact
Apply example.
Embodiment
As shown in Figure 1-2, a kind of drill bit with water injector, including the drill body provided with apex point end and installation end；Institute
The apex point end for stating drill body is provided with hole for water spraying 1, and installation end side wall is provided with least one centrifugation water supply installation 2；The centrifugation supplies
The delivery outlet of water installations 2 connects by one along the axially extending water cavity of drill body with hole for water spraying 1；
The centrifugation water supply installation 2 includes a socket and is fixed on shell on drill body installation end, the shell it is outer
Surface is anchor ring, and the enclosure has toroidal cavity, be arranged with the toroidal cavity using the rotating shaft of drill body as
A pair of water pressurizing devices 3 of symmetry axis, the shell are provided with water filling port and the thread plug 4 to match with water filling port；
One is provided with the water pressurizing device 3 with the column water cavity 3.1 of a diameter of axis of the centrifugation water supply installation 2, it is described
One first ndfeb magnet is fixed with the outer face of column water cavity 3.1, a metallic piston is additionally provided with the column water cavity 3.1
3.2；Second ndfeb magnet mutually repelled with first ndfeb magnet is fixed with the end face of the metallic piston 3.2
3.3；
The outer end side wall of water pressurizing device 3 is provided with the input port 3.4 connected with the toroidal cavity；
