Blade structure diagram.
The utility model, which rotates drill bit of removing obstacles, includes drill body 11, and high pressure water receiving cavity is provided with drill body 11
111, the rear end of drill body 11 is provided with the water filling port 112 for injecting high pressure water flow into high pressure water receiving cavity 111, should
Rotate and high-pressure water pipe is connected at the water filling port 112 for drill bit of removing obstacles for injecting high pressure water into high pressure water receiving cavity 111.
The a plurality of spiral channel from top to bottom penetrated through along cavity wall 114 is provided with the cavity wall 114 of high pressure water receiving cavity 111
113, as shown in Fig. 2, Fig. 2 is equivalent to the interior views after cavity wall 114 is splitted along spiral channel 113, in cavity wall 114 formed with
A plurality of spiral helicine duct, these ducts are spiral channel 113, as shown in figure 4, the rear observation for drill bit of removing obstacles from the rotation,
Spiral channel 113 includes water inlet 1131 and water outlet 1132, and water inlet 1131 is respectively positioned on the top of high pressure water receiving cavity 111
Wall on, water outlet 1132 is respectively positioned on the outer surface of 11 lower part of drill body, so that in high pressure water receiving cavity 111
High pressure water is entered corresponding spiral channel 113 and flowed out by water outlet 1132 by water inlet 1131 to be applied with drill bit of removing obstacles to rotation
Add forward driving force and the turning power rotated.
The rotation remove obstacles the connection of drill bit rear end water pipe in the high pressure water that conveys enter in high pressure water receiving cavity 111, then
Enter spiral channel 113 from the water inlet 1131 on the top of high pressure water receiving cavity 111, and by removing obstacles drill bit positioned at the rotation after
The water outlet 1132 of portion outer surface flows out, and the high pressure water conveyed in the water pipe for drill bit rear end connection of removing obstacles equivalent to the rotation enters
Flow at high speed in the opposite direction after in high pressure water receiving cavity 111, removes obstacles the rotation while high pressure water flows backward
Drill bit is applied with an opposition F（Shown in Fig. 3）.
High pressure water in high pressure water receiving cavity 111 has kinetic energy when being sprayed through water outlet 1132, its instantaneous energy it is big
Small available formula W=1/2mv2, wherein, m represents the quality per second for spraying water of water outlet 1132, and v represents 1132 water outlet of water outlet
Instantaneous velocity, W represent the kinetic energy size of the water of the ejection of water outlet 1132, and m and/or v are bigger, and W is bigger.It is fixed according to newton the 3rd
Rule understands that the water that water outlet 1132 sprays, which acts on rotation and removes obstacles on drill bit, an opposition F, by control m and/or
The size of v can adjust the size of opposition F.

When high pressure water in pressure water receiving cavity 111 is flowed through by 113 high speed of spiral channel, from the high pressure water pair of the outflow of water outlet 1132
Rotation remove obstacles drill bit application opposition F can be decomposed into the radial load F1 of the plane tangent of cavity wall 114 and with rotation
Turn remove obstacles drill bit axis parallel axial force F 2, radial load F1 to rotation remove obstacles drill bit apply revolution radial direction torque promote
Rotation is removed obstacles drilling bit high-speed rotation, and axial force F 2 promotes rotation to remove obstacles drill bit high-speed motion forward.
The helically arc on the whole of spiral channel 113, water outlet 1132 and the rotation of spiral channel 113 are removed obstacles in drill bit
The angle α of axis is 30 °~60 °, and the angle α of central axes of the water outlet 1132 with rotating drill bit of removing obstacles is bigger, rotates brill of removing obstacles
The radial load F1 that is subject to of head is bigger, and rotation drill bit of removing obstacles rotates faster, and water outlet 1132 and rotation are removed obstacles the central axes of drill bit
Angle α is smaller, and the rotation axial force F 2 that drill bit is subject to of removing obstacles is bigger, rotation remove obstacles drill bit advance it is faster, according to different uses
Demand, different size of angle is arranged to by water outlet 1132 and the angle α for the central axes for rotating drill bit of removing obstacles.Spiral channel
113 helically arcs, can be such that the high pressure water in high pressure water receiving cavity 111 more smoothly flows out.
As shown in figure 4, spiral channel 113 is provided with six, six spiral channels 113 construct it is identical, and in the high pressure water capacity
Receive cavity 111 cavity wall 114 in be uniformly distributed, the water outlet 1132 of spiral channel 113 is respectively positioned on high pressure water receiving cavity 111
On lower face 1111.Six water inlets 1131 on 111 top wall of high pressure water receiving cavity and six are corresponding with Fig. 4
Water outlet 1132 on the lower face 1111 of high pressure water receiving cavity 111.Spiral channel 113 uniformly divides in cavity wall 114
Cloth is conducive to the uniform thrust of drill bit application of removing obstacles to rotation, and water outlet 1132 is arranged on high pressure water receiving cavity 111
On lower face 1111 so that the reaction force for drill bit application of removing obstacles from the high pressure water that water outlet 1132 flows out to rotation decomposes completely
For axial force F 2 and radial load F1, reaction force F is more efficiently utilized.The rotation power that drill bit is subject to of removing obstacles is six spiral shells
The high pressure water that the water outlet 1132 of rotation water channel 113 sprays is made a concerted effort to rotating drill bit application of removing obstacles.
In the present embodiment, the spiral channel 113 in cavity wall 114 is the hole that cross section is circular smooth spiral arc, but
The shape not limited to this of spiral channel 113, can also be that along cavity wall 114 with convolution angle, cross section is triangle or side
The hole of the smooth spiral arc of shape, can also be that the multistage straight line shaped hole connection that convolution angle is penetrated through, had along cavity wall 114 forms
Through hole, as long as perforation and being passed through high pressure along the remove obstacles hole of the central axes revolution certain angle of drill bit of rotation in the cavity wall 114
It can promote to rotate the requirement that drill bit advances with rotation of removing obstacles after water.
Drill body 11 is bullet shape, and high pressure water receiving cavity 111 is corresponding bullet shape, such as Fig. 4
