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.
