Wherein, the lubricator storage space 15 of sealing is formed between the lower face of cylinder body 6 and the inclined surface 111 of swash plate,
The cavity of a closing is formed i.e. between rotation axis 5, cylinder body 6, swash plate 11 and outer barrel 13, which contains greasing substance
Each kinematic pair is lubricated, and greasing substance will not be leaked into outside the closed cavity；Greasing substance is solid lubrication
Fat or other common lubriation materials.Rotation axis 5 and valve plate 4 are equipped with the lifting passage that can lift landwaste, rotation axis 5 it is interior
Portion is equipped with 51 and second axial passage 52 of first axis passage mutually separated；Valve plate 4 is equipped with mutually independent first flow
Passage 41 and second matches somebody with somebody circulation road 42, and first connects with circulation road 41 with first axis passage 51, second match somebody with somebody circulation road 42 and
Second axial passage 52 connects.By rotation axis 5 cylinder body 6 is driven to rotate, compulsory push-pull effort is applied to plunger body 7 by swash plate 11
Form straight reciprocating motion of the plunger body 7 in plunger hole 61.The landwaste that drill bit drilling well is formed is mixed to form with the liquid in shaft bottom
Solidliquid mixture makes landwaste (drilling cuttings) by lifting passage to lift by the castering action of plunger body 7.According to the lifting device institute
It is required that the scope of grain diameter coordinate corresponding drill bit, prove in certain particle size range and coordinate in actual use
Liquid makes landwaste and liquid forms solidliquid mixture, which can reach lifting effect well.
Further, the inside of rotation axis 5 is sequentially coaxially equipped with the first axis passage 51 that mutually separates and the from bottom to top
Two axial passages 52 have the first separating part 53 between 51 and second axial passage 52 of first axis passage.First separating part 53
5 side wall of rotation axis of lower section is equipped with the multiple first connection windows 54, is set on the side wall of the rotation axis 5 of 53 top of the first separating part
There are multiple second connection windows 55.It can be the side wall circumference along rotation axis 5 that first connection window 54 connects window 55 with second
The multiple through slots being uniformly arranged respectively connect 51 and second axial passage 52 of first axis passage with 5 outside of rotation axis.
Inclined surface 111 has a peak and a minimum point, setting peak, minimum point and cylindrical interior space
Plane where axis is the first division surface A, orthogonal with the first division surface A and by the plane of cylindrical interior space axis be
Second division surface B.As shown in Figures 2 to 4, first is located at the second division surface B respectively with circulation road 41 and second with circulation road 42
Both sides.First opens wide with lower end of the circulation road 41 and second with circulation road 42, extend to the upper surface of cylinder body 6 simultaneously can with it is right
The plunger hole 61 answered connects.First is located at one side corresponding with minimum point with circulation road 41, and first matches somebody with somebody circulation road 41 and first
Axial passage 51 is connected by the first connection window 54, and first connects window 55 by rotation axis with matching somebody with somebody with circulation road 41 with second
Rotary seal partition between flow table.Second is located at one side corresponding with peak with circulation road 42, and second matches somebody with somebody circulation road 42
Window 55 is connected with the second axial passage 52 by second to connect, second connects window 54 with circulation road 42 with first passes through rotation
Rotary seal partition between axis and valve plate.Wherein first axis passage 51, the second axial passage 52, first connection window
54th, the second connection window 55, first forms lifting passage with circulation road 41 and second with circulation road 42.Specifically, the first flow
The top of passage 41 is located at the first connection window 54 and is connected with second between window 55；Second top with circulation road 42 is higher than the
The bottom of two connection windows 55.As shown in Figures 2 to 4, first matches somebody with somebody circulation road 42 perpendicular to cylinder with circulation road 41 and second
Shape inner space axis is that the projection on the cross section of rotation axis 5 is sector.
Plunger body 7 can move in the plunger hole 61 of cylinder body 6, form the cavity of variable volume.When plunger body 7 and piston shoes 9
When being rotated together with cylinder body 6, piston shoes 9 can only move in the T-shaped sliding slot 112 of swash plate 11, so as to which swash plate 11 passes through 9 strength of piston shoes
Plunger body 7 is pushed and pulled, is allowed to do straight reciprocating motion, the swept volume for the cavity that plunger body 7 and plunger hole 61 are formed will occur
Variation accommodates landwaste and discharge landwaste by the variation of swept volume to realize.Plunger body 7 turns round from top to bottom along swash plate 11
Half cycle in gradually overhang to cylinder body 6, be continuously increased the swept volume in plunger hole 61, generate local space, work hold
When product becomes larger, well drilling detritus is admitted to first with circulation road 41 by the connection window 54 of first axis passage 51, first and enters
Swept volume.It is gradually pushed into again into plunger hole 61 in the half cycle that plunger body 7 is turned round from bottom to top, makes working chamber volume continuous
Reduce, the swept volume formed with plunger body 7 and plunger hole 61 becomes smaller, while turns to second with 42 position of circulation road, bores
Well landwaste enters the second axial passage 52 with the connection window 55 of circulation road 42, second by second from swept volume and is lifted.
6 every revolution of cylinder body, each plunger body 7 move back and forth once, complete once to be sent into and release lifting action.
Further, as shown in figure 4, the side wall of cylinder body 6 is equipped at least one first footpath connected with each plunger hole 61
To open-work 62, the first radial through holes 62 connect plunger hole 61 with 6 outside of cylinder body.On the side wall of outer barrel 13 with the first radial through holes
62 highly consistent positions are equipped at least one second radial through holes 131, and the second radial through holes 131 are by the inside of outer barrel 13 and outside
Portion connects.On at least one both inner wall of outer barrel 13 and the outer wall of cylinder body 6, with the first radial through holes 62 and the second radial through holes
131 highly consistent positions are equipped with annular groove 16, and annular groove 16 connects the first radial through holes 62 and the second radial through holes 131
It is logical.It is gap-matched between the outer diameter of plunger body 7 and the internal diameter of plunger hole 61, which is enough to prevent landwaste powder particle
By, but can ventilate, so that the pressure and the ambient pressure that are more advantageous in plunger hole 61 balance each other, plunger body 7 and plunger hole
It is sealed between 61 using sealing ring, which is located at the lower section of the first radial through holes 62, can prevent greasing substance from leaking.
For example, it is the plunger portion being relatively large in diameter, the form that lower part is the smaller piston rod of diameter that top, which may be employed, in plunger body 7, plunger
Portion and the inner wall clearance sliding fit of plunger hole 61, the gap can prevent landwaste powder particle from entering, piston rod and plunger hole 61
Inner wall between have gap and pass through sealing ring seal, when plunger body 7 moves to the position of the top, piston rod and plunger
Sealing ring between 61 inner wall of hole is still located at 62 lower section of the first radial through holes, will not block first radial through holes 62, the sealing
