Abstract
The utility model discloses a kind of high-pressure water jet rock drilling waterpower drill bits, it includes drill main body and nozzle, fluidic channel is set in drill main body, the input port bore of fluidic channel is greater than delivery outlet bore, and nozzle is assemblied in the equipped at outlet port of fluidic channel;The fluidic channel includes input cavity and output cavity, and input cavity includes straightway and hemisphere section, and output cavity is connected to outside hemisphere section, and the outlet of output cavity is horn mouth;The output cavity has multiple, the straightway coaxial arrangement of one of them and input cavity, axial centre circular array arrangement of other output cavities about straightway.In use, high pressure water realizes cutting grinding rock drilling from the nozzle output of output end after fluidic channel from after input terminal entrance, since fluidic channel bore reduces from input terminal to output end, so as to further increase the pressure of jet stream, rock drilling effect is improved.
Description
Technical field
The utility model relates to a kind of drill bits, more particularly to a kind of high-pressure water jet rock drilling waterpower drill bit.
Background technique
Existing rock drilling machine mainly has air rock drill and hydraulic chisel machine, and drills for stone are mainly rotated by mechanical high-speed
It squeezes and grinding rock stratum.Big capacity industrial waste gas can be generated using pneumatic, hydraulic rock, mechanical rock breaking can generate a large amount of dust, right
Environment causes seriously to pollute, and causes damages to worker's health, and production efficiency is low.And current drill bit is difficult to use in
High-pressure water jet rock drilling.
Utility model content
The purpose of this utility model is to provide one kind can be realized waterpower cutting, guarantees the high-pressure water jet of jet pressure
Rock drilling waterpower drill bit.
This high-pressure water jet rock drilling waterpower drill bit provided by the utility model, it includes drill main body and nozzle, is bored
Fluidic channel is set in head main body, the input port bore of fluidic channel is greater than delivery outlet bore, and nozzle is assemblied in the defeated of fluidic channel
Exit;The fluidic channel includes input cavity and output cavity, and input cavity includes straightway and hemisphere section, and output cavity is connected to
Outside hemisphere section, the outlet of output cavity is horn mouth;The output cavity has multiple, one of them is coaxial with the straightway of input cavity
Setting, other output cavities are arranged about the axial centre circular array of straightway.
In one embodiment, for the ease of assembly, make the drill main body hexagonal prisms, the output end of drill main body
End face be externally provided with carbide bit.
For the ease of connection, the drill main body corresponds to inner wall peripheral hardware screw thread at input cavity.
In a specific embodiment, make the nozzle ruby nozzle.
When the utility model is used, high pressure water exports after fluidic channel from the nozzle of output end from after input terminal entrance
Cutting grinding rock drilling is realized, since fluidic channel bore reduces from input terminal to output end, so as to further increase jet stream
Pressure, improve rock drilling effect.
Detailed description of the invention
Fig. 1 is the schematic cross-sectional view of one preferred embodiment of the utility model.
Fig. 2 is the vertical view enlarged diagram of Fig. 1.
Fig. 3 is the enlarged diagram of A-A in Fig. 1.
Illustrate serial number:
A-drill main body, a1-fluidic channel, a11-input cavity, a12-output cavity,
B-nozzle,
C-carbide bit.
Specific embodiment
As shown in Figure 1, this high-pressure water jet rock drilling waterpower drill bit provided in this embodiment includes drill main body a and spray
Mouth b.
As shown in Figure 1, Figure 2, Figure 3 shows, drill main body a is hexagonal prisms, and one end is input terminal, the other end is output end, defeated
Carbide bit c is provided with outside the entity of outlet.
The fluidic channel a1 that bore reduces from input terminal to output end, fluidic channel are equipped at the axial centre of drill main body
Packet a1 includes input cavity a11 and output cavity a12；Input cavity is set to the axial centre of drill main body, and the outer wall of input cavity is equipped with spiral shell
For line in order to be connected with drilling rod, input cavity includes straightway and hemisphere section, and output cavity is connected to outside hemisphere section；Output cavity has four
A, one of them is coaxially disposed with input cavity, and the other three is arranged about the longitudinal center line circular array of input cavity, each defeated
The outlet of chamber is assembly of the horn mouth in order to nozzle b out.
Nozzle b is that selection is ruby nozzle, is assemblied in output cavity.
It is connect when the present embodiment is in use by input terminal with drilling rod spiral, high pressure water enters in drill bit from input terminal, so
Cutting grinding rock drilling is realized from the output of the nozzle of output end by after fluidic channel, since fluidic channel bore is from input terminal to defeated
Outlet reduces, and the pressure of water jet is further increased by ruby nozzle, improves rock drilling effect.
