Described first thread segment 22 is between the second thread segment 13 and the 3rd thread segment 11;
Motor drives planet carrier 41 to rotate, then planet carrier 41 drives the rotation of each planetary gear 43 and revolves round the sun around center sun gear 42, and the rotation of planetary gear 43 drives the rotation of center sun gear 42; Therefore, the rotating speed of partial screw threads shell 2 and planet carrier 41 is identical, if the rotating speed of the two is V
1, and intermittent screw thread axle 1 is identical with the rotating speed of center sun gear 42, if the rotating speed of the two is V
2, then V
1< V
2, and V
1and V
2rotation direction be also identical.Suppose V
1and V
2be and rotate clockwise (seeing from top to bottom), then owing to there is speed discrepancy, partial screw threads shell 2 rotates counterclockwise relative to intermittent screw thread axle 1, therefore described partial screw threads shell 2 is when rotating relative to intermittent screw thread axle 1, the lower end of the upper end of described first thread segment 22 and the second thread segment 13 periodically near and away from, the upper end of its lower end and the 3rd thread segment 11 periodically near and away from, pressure when relying on close to each other, thus can drilling cuttings be crushed, mutually away from rear, first thread segment 22, drilling cuttings can upwards be carried again by the second thread segment 13 and the 3rd thread segment 11.
Further, described first thread segment 22, second thread segment 13 is equal with the pitch of the 3rd thread segment 11 and rotation direction is consistent, so that intermittent screw thread axle 1 to be successfully installed to partial screw threads shell 2 inside.
Further, two ends of described first thread segment 22 have upper surface and lower surface respectively, described second thread segment 13 and the 3rd thread segment 11 have lower surface and upper surface respectively, and 22 upper surfaces of described first thread segment and lower surface can coordinate with the lower surface of the second thread segment 13 and the upper surface of the 3rd thread segment 11 respectively and crush drilling cuttings.Rely on end face instead of helical flank to extrude drilling cuttings, effectively can promote extruding force, easier drilling cuttings to be crushed.
Further, described second thread segment 13 and the 3rd thread segment 11 all with the contact internal walls of the housing of partial screw threads shell 2, to be enclosed on each thread segment by drilling cuttings better, prevent drilling cuttings from dropping downwards.
Further, the top of described intermittent screw thread axle 1 is provided with bearing linkage section 14, the diameter of described bearing linkage section 14 is greater than the large footpath of the second thread segment 13, and the position that it is corresponding to the second thread segment 13 is provided with multiple groove 15, exports from groove 15 to make the drilling cuttings on the second thread segment 13.Bearing linkage section 14 is provided with bearing 5, bearing 5 comprises bearing body 51 and bearing cover 52, the lower end of bearing cover 52 is fixedly connected with and extends boss 53, motor is fixedly connected on by motor adapter sleeve and extends on boss 53, partial screw threads shell 2 is fixedly connected on again on bearing cover 52, motor first rotates by extending boss 53 driving bearing lid 52, and bearing cover 53 just can 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, and by point speed of planetary gearsets 4, speed is passed to intermittent screw thread axle 1 by partial screw threads shell 2, and the two rotates (seeing from top to bottom) with different clockwise direction.Intermittent screw thread axle 1 has the 3rd thread segment 11, optical axis section 12, second thread segment 13, bearing linkage section 14 and groove 15.Partial screw threads shell 2 has light wall portion 21, first thread segment 22, planet carrier adpting flange 23 and bearing cover adpting flange 24.The drilling cuttings accumulation that drill bit produces enters into intermittent screw thread axle 1 lower end, under the inwall of partial screw threads shell 2 and the effect of intermittent screw thread axle 1, drilling cuttings rises gradually, rise to optical axis section 12 place of intermittent screw thread axle 1, the drilling cuttings that the lasting rising due to lower end drilling cuttings will promote upper end is slowly filled into optical axis section 12 place of intermittent screw thread axle 1.
As shown in Figure 3, Figure 4, when drilling cuttings is filled into the optical axis section 12 of intermittent screw thread section 1, along with relatively rotating of intermittent screw thread axle 1 and partial screw threads shell 2, first thread segment 22 upper end will periodically with the lower end of second segment screw thread 13 near with away from, the first thread segment 22 lower end will periodically with the upper end of the 3rd section of screw thread 11 near with away from.Need to guarantee near after can not contact, such partial screw threads shell 2 and intermittent screw thread axle 1 would not produce when rotating interferes and stops operating.Drilling cuttings will be extruded reach crushing effect in approach process, away from after will continue upwards to carry drilling cuttings, get a desired effect.
As shown in Figure 5, planet carrier 41 comprises planetary gear coupling part 411 and drill bit coupling part 412.Drill bit is connected on drill bit coupling part 412, and planetary gear is just between each drill bit coupling part, each other without interruption.
