Specific embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.As long as additionally, technical characteristic involved in invention described below each implementation method
Not constituting conflict each other can just be mutually combined.
As shown in figure 1, a kind of drilling well drilling cuttings conveys breaker, including fixing shell 3, planetary gearsets 4, local spiral shell
Line shell 2 and intermittent screw thread axle 1, wherein,
The fixing shell 3 is used to be arranged in ground to be supported, its is circumferentially fixed and move without spin, but can be with
By other mechanism urges, it produces axial feed motion；
The planetary gearsets 4 include gear ring 44, center sun gear 42, planet carrier 41 and multiple planetary gears 43, wherein, institute
Gear ring 44 is stated to be arranged on the inwall of the fixing shell 3；
The partial screw threads shell 2 is driven by motor and rotated, and its top for being located at the planet carrier 41 simultaneously fixedly mounts
On the planet carrier 41, it includes housing 21 and is arranged on the first thread segment 22 of inner walls；
The intermittent screw thread axle 1 is passed through from the inside of the partial screw threads shell 2 and its lower end is arranged on the center
On sun gear 42, it includes axis body 12 and is arranged on second thread segment in the outside of axis body 12 and positioned at the lower section of the second thread segment 13
3rd thread segment 11, is light shaft part 12 between the thread segment 11 of second thread segment 13 and the 3rd；
First thread segment 22 is located between the second thread segment 13 and the 3rd thread segment 11；
Motor drives planet carrier 41 to rotate, then planet carrier 41 drives each rotation of planetary gear 43 and around the public affairs of center sun gear 42
Turn, and the rotation of planetary gear 43 drives the rotation of center sun gear 42；Therefore, partial screw threads shell 2 and planet carrier 41 turn
Speed is identical, if the rotating speed of the two is V1, and intermittent screw thread axle 1 and the rotating speed of center sun gear 42 are identicals, if the two
Rotating speed be V2, then V1＜ V2, and V1And V2Rotation direction be also identical.Assuming that V1And V2Be and rotate clockwise (from
On look down), then due to there is speed discrepancy, partial screw threads shell 2 is rotated counterclockwise relative to intermittent screw thread axle 1, therefore
The partial screw threads shell 2 when being rotated relative to intermittent screw thread axle 1, the upper end of first thread segment 22 and the second thread segment 13
Lower end periodically near and away from, its lower end and the 3rd thread segment 11 upper end periodically near and away from, by mutually leaning on
Pressure when near, so as to crush drilling cuttings, after being located remotely from each other, the first thread segment 22, the second thread segment 13 and the 3rd thread segment 11
Drilling cuttings can be delivered up again.
Further, the pitch of first thread segment 22, the second thread segment 13 and the 3rd thread segment 11 is equal and rotation direction one
Cause, in order to intermittent screw thread axle 1 is successfully installed to inside partial screw threads shell 2.
Further, two ends of first thread segment 22 have upper surface and lower surface, second screw thread respectively
The thread segment 11 of section 13 and the 3rd has lower surface and upper surface respectively, and 22 upper surfaces and lower surface of first thread segment can be divided
Crushing drilling cuttings is not coordinated with the lower surface of the second thread segment 13 and the upper surface of the 3rd thread segment 11.By end face rather than spiral
Side extrudes drilling cuttings, can effectively lift extruding force, it is easier to crush drilling cuttings.
Further, inwall of the thread segment 11 of second thread segment 13 and the 3rd with the housing of partial screw threads shell 2 connects
Touch, so that preferably drilling cuttings is enclosed on each thread segment, prevent drilling cuttings from dropping downwards.
Further, the top of the intermittent screw thread axle 1 is provided with bearing linkage section 14, and the diameter of the bearing linkage section 14 is big
In the big footpath of the second thread segment 13, it is provided with multiple grooves 15 in the position corresponding to the second thread segment 13, so that the second spiral shell
Drilling cuttings in line section 13 is exported from groove 15.Bearing 5 is installed, bearing 5 includes the He of bearing body 51 on bearing linkage section 14
Bearing cap 52, the lower end of bearing cap 52 is fixedly connected with extension boss 53, and motor is fixedly connected on extension by motor connection set
On boss 53, partial screw threads shell 2 is stationarily connected on bearing cap 52 again, and motor first passes through the extension driving bearing of boss 53
Lid 52 rotates, and bearing cap 53 can just drive partial screw threads shell 2 have rotated.
As shown in Fig. 1, Fig. 3, Fig. 4.Motor drives partial screw threads shell 2 to rotate, by point speed, office of planetary gearsets 4
Speed is passed to intermittent screw thread axle 1 by portion screw thread shell 2, and the two turns clockwise (viewed from above) at different rates.Between
Disconnected thread spindle 1 has the 3rd thread segment 11, light shaft part 12, the second thread segment 13, bearing linkage section 14 and groove 15.Partial screw threads
Shell 2 has light wall part 21, the first thread segment 22, planet carrier adpting flange 23 and bearing cap adpting flange 24.Drill bit is produced
Drilling cuttings accumulation enter into the lower end of intermittent screw thread axle 1, in the presence of inwall and the intermittent screw thread axle 1 of partial screw threads shell 2, bore
Bits are gradually increasing, and rise at the light shaft part 12 of intermittent screw thread axle 1, because the lasting rising of lower end drilling cuttings will promote upper end
Drilling cuttings is slowly filled at the light shaft part 12 of intermittent screw thread axle 1.
As shown in Figure 3, Figure 4, when drilling cuttings is filled into the light shaft part 12 of intermittent screw thread section 1, with intermittent screw thread axle 1 and office
The relative rotation of portion screw thread shell 2, the upper end of the first thread segment 22 will periodically with the lower end of second segment screw thread 13 near with
Away from, the lower end of the first thread segment 22 will periodically with the 3rd section of upper end of screw thread 11 near with away from.It is necessary to ensure that after
Will not contact, such partial screw threads shell 2 and intermittent screw thread axle 1 would not produce interference when rotating and stop operating.Leaning on
Drilling cuttings will be extruded near procedure and reaches crushing effect, will continue to be delivered up drilling cuttings away from after, got a desired effect.
As shown in figure 5, planet carrier 41 includes planetary gear coupling part 411 and drill bit coupling part 412.Drill bit is connected to
On drill bit coupling part 412, planetary gear just between each drill bit coupling part, each other without interruption.
As it will be easily appreciated by one skilled in the art that the foregoing is only presently preferred embodiments of the present invention, it is not used to
The limitation present invention, all any modification, equivalent and improvement made within the spirit and principles in the present invention etc., all should include
Within protection scope of the present invention.
