Being assemblied in block by back-moving spring 18, this slide block mates with the guide chute 10 of cam 9.
Main second cylinder sleeve 15 of above-mentioned rigid scraper mechanism 14, flexible member and wing 22 form, described second cylinder sleeve
15 circumferences are provided with least one set blade groove, and described wing 22 is fitted in blade groove by flexible member radially loading.Wherein, institute
The wing 22 stated on the second cylinder sleeve 15 assembles in blade groove by pressing plate 16, and this pressing plate 16 is fixed on second by trip bolt 17
On cylinder sleeve 15 (that is, the wing 22 on described second cylinder sleeve 15 is installed by the pressing plate 16 at blade groove two ends).Further, described
Blade groove on second cylinder sleeve 15 is two groups, and these two groups of blade groove are axially in circumferentially staggered arrangement；In described this utility model
Flexible member be back-moving spring 20.
The end of above-mentioned mandrel 13 is provided with float 23 and plug 25, the first cylinder sleeve 2 between float 23 and plug 25
Through hole 24 is had on wall；Above-mentioned piston 7 is provided with sealing structure on mandrel 13 outer surface of mandrel 13 junction；Above-mentioned float
23 bottoms are provided with sealing structure；Above-mentioned first cylinder sleeve 2 is divided into upper and lower two parts to form, and upper part is assembled bearing mechanism and leads
To mechanism etc., lower part assembling wing etc., above-mentioned mandrel 13 is assemblied in the first cylinder sleeve 2 by guiding mechanism and back-moving spring
In, this back-moving spring one end is supported to guiding mechanism, and the other end supports to upper and lower two parts of the first cylinder sleeve 2 points.
Work process:
When mandrel 13 is in original position, spacer pin 11 is positioned in the guide chute 10 of cam 9 at primary importance W1, scrapes
Blade 21 is in contraction transition.
For the first time after turn on pump, under mud pressure effect, force mandrel 13 to move down, the cam 9 on mandrel 13 also with
Move down, spacer pin 11 is fixed on the first cylinder sleeve 2 simultaneously, will not move so that cam 9 occurs relative to spacer pin 11
Rotating, spacer pin 11 slides in guide chute 10, and spacer pin 11 slides primary importance W1 by guide chute 10 to guiding
At second position W2 of chute 10, now spacer pin 11 leans with guiding to slide, when cam 9 no longer moves down, and mandrel 13
Also cannot continue to move down, the descending distance of this stage mandrel 13 is L1.Meanwhile, piston 7, the most downward descending L1 of orifice plate carrier 6
Distance.Now, valve rod 5 is still located in orifice plate carrier 6 endoporus, all mud must from valve rod 5 and orifice plate carrier 6, formed narrow
Little annular space passes through, and now area of passage is minimum, so mud pressure is the highest；Meanwhile, wing 21 is still in shrinking transition.
Subsequently, slush pump stops for the first time, and mud annular pressure sheds, under the effect of back-moving spring 19, mandrel 13 to
Upper movement, now, spacer pin 11 slides at the 3rd position W3 at second position W2 of the guide chute 10 of cam 9, orifice plate carrier 6
Return to initial position.
When slush pump second time starts, and mandrel 13 moves down, and cam 9 moves down the most therewith, and spacer pin 11 is led from cam 9
Sliding at the 4th position W4 at the 3rd position W3 of chute 10, then slide to the 5th position W5, now spacer pin 11 is slided with guiding
Groove 10 leans, and cam 9 no longer moves down, and mandrel 13 also cannot continue to move down, and the descending distance of this stage mandrel 13 is L2.
Meanwhile, the distance of piston 7, orifice plate carrier 6 also downward L2.Now, valve rod 5 leaves orifice plate carrier 6 endoporus, the annular space between them
Passage becomes suddenly big, when comparing with first time turn on pump, in the case of discharge capacity is identical, owing to circulation passage becomes big, makes system
Mud pressure reduces；Meanwhile, wing 21 is the state of stretching out.
Subsequently, slush pump second time stop, mud annular pressure sheds, under the effect of back-moving spring 19, mandrel 13 to
Upper movement, now, cam 9, orifice plate carrier 6 etc. all return to initial position.
As above circulate, thus pass through startup and the stopping of slush pump so that it is rigid scraper mechanism is in different work shapes
State.When mud pressure is higher, the rigid scraper mechanism of this utility model patent 1 is in contraction state, now, and flexible scraper mechanism
1 in work；When mud pressure is relatively low, the rigid scraper mechanism of this utility model patent 1 is in the state of stretching out, and can remove obstinate dirty
Dirt.
Concrete technical scheme is only in order to illustrate this utility model above, is not intended to limit.Although with reference to above-mentioned concrete skill
This utility model has been described in detail by art scheme, it will be understood by those within the art that: it still can be right
Above-mentioned concrete technical scheme is modified, or wherein portion of techniques feature is carried out equivalent；And these are revised or replace
Change, do not make the essence of appropriate technical solution depart from spirit and scope of the present utility model.
