On seat 4；7 bottom of said inner tube is connect with clip spring seat 4, and top is connect with inner tube top connection 10；10 top of said inner tube top connection
It is threadedly coupled with plug 12；The outside of connector 10 on inner pipe is arranged in the spring 11, and one end of spring 11 is provided with spring pad
I 9 are enclosed, the other end is provided with spring washer II 13；
The outer pipe assembly includes reamer 6 and outer tube 8；The outside of inner tube 7 is arranged in the outer tube 8；The reamer 6
It is arranged on outer tube 8；
It is logical that the described setting of friction element 2 there are two friction operation block 201, between friction operation block 201 is provided with liquid stream
Road 202, each 2 upper outside of friction element are provided with bridging structure 203；
3 bottom of steel body is provided with fan-shaped boss 301, and 301 inner wall two sides of each sector boss are respectively arranged with interior
Spacing block set 302 is provided with friction element slot 303 between two fan-shaped boss 301；
The clip spring seat 4 that fluid pressure inner tube assembly is connect on the friction element 2 realizes upper limit, by the friction of steel body 3
Member slot 303 realizes outer limit, the drill bit mouth of a river is collectively formed by friction element slot 303 and fluid course 202, by interior spacing block set

Pressure inner tube assembly transmits axial compressive force to friction element 2；
The course of work and principle of the utility model are as follows:
When drilling tool does not reach bottom hole, the bridging structure 203 of friction element 2 is directly seated the fan-shaped boss 301 of steel body 3
On, limitation friction element 2 is continued traveling downwardly with liquid pressing inner tube assembly, and impregnated Buddha's warrior attendant lithopedion is compared in 201 bottom surface of friction operation block
Protrude 2mm~4mm in 1 bottom surface of body.After drilling tool and bottom hole rock contact, friction element 2 and fluid pressure inner tube assembly uplink, at this time
201 bottom surface of friction operation block is equal with impregnated 1 bottom surface of diamond matrix, the drill bit mouth of a river by friction element 2 fluid course 202 with
The friction element slot 303 of steel body 3 collectively forms, and 202 height of fluid course is greater than distance of the friction element slot 303 away from bottom hole, because
In drilling process, mouth of a river area only wears with impregnated diamond matrix 1 related for this, and wears with friction element 2 unrelated.
Impregnated diamond matrix 1 with axially downwardly pressure is generated by drilling machine apparatus for feeding respectively suffered by friction element 2
Axial force and drilling fluid be applied to liquid pressing inner tube assembly pressure provide.Liquid pressing inner tube assembly top is by interior
Pipe top connection 10, spring 11, spring washer and plug 12 form.10 upper portion pipe body of inner tube top connection is provided with circular through hole, blocks up
First 12 outside diameter is greater than II 13 internal diameter of spring washer, and plug 12 is limited on spring 11 and spring washer II 13 after connection.
Plug 12 and spring washer II 13 close 8 drilling fluid flow channel of outer tube, when drilling fluid is flowed through to liquid pressing inner tube assembly
When top, liquid constricted flow, 8 central passage fluid pressure of outer tube increases severely.Fluid pressure a part acts on plug 12, makes
Liquid pressing inner tube assembly constantly transmits pressure to friction element 2, frictionally heats bottom hole rock；Another part acts on bullet
On spring washer II 13, downward compressed spring 11 to circular through hole, drilling fluid enters inner tube 7 through circular through hole, and then reaches bottom hole
Cooling drill bit.While drilling fluid enters inner tube 7 through circular through hole, flow stream pressure decline, spring 11 will be sprung back.Spring
11 periodic compression and springback process fluid passage can be formed it is intermittent unlatch and close effect so that drilling fluid with
Impulse form flow to bottom hole.When fluid passage is closed, rock frictional test acting surface temperature is further promoted, rock attenuation
Enhancing, further increases drilling tool drilling efficiency.
When drilling tool, which is transferred, starts drilling to bottom hole, impregnated diamond matrix 1 friction operation block 201 structure adjacent with left and right
At a working cell, in drilling tool turning course, previous friction operation block 201 generates higher rub with rock interaction
Chafing can weaken rock, and subsequent impregnated 1 working lining of diamond matrix and rock act on fractured rock, and generate less frictional heat
Can, amount of residual heat further promotes rock after subsequent the latter friction operation block 201 acts on rock using impregnated diamond matrix 1
Acting surface temperature is acted on compared to single friction operation block, can be greatly improved drilling fluid and be rinsed front and back rock acting surface temperature difference, bright
The aobvious frictional heat energy that promoted weakens rock effect, substantially increases drilling efficiency.
