Specific embodiment: when people are in the well-digging mechanism designed using the present invention, driving motor 2 works, driving electricity Machine 2 just will drive the rotation of first rotating shaft 14；The rotation of first rotating shaft 14 just will drive the first swing rod 11 around 14 axis of first rotating shaft Rotation；The rotation of first swing rod 11 just will drive the swing of the second swing rod 23；Second swing rod 23 swing just will drive flexible swing rod 24 around 19 axis of the second shaft rotation；The flexible rotation of swing rod 24 just will drive the rotation of the second shaft 19.In the initial state, stretch pendulum The shortest length of bar 24 is identical as the length of the first swing rod 11.In this case, the 4th gear 38 will drive 5 turns of mounting shell It is dynamic；The rotation of mounting shell 5 drives corresponding installation drive ring 35 to rotate by corresponding arc drive block 43；35 turns of drive ring of installation It is dynamic that screw blade 10 is driven to rotate；Second shaft, 19 meeting simultaneously is so that eight connection shafts 44 in eight regulating mechanisms 56 all can Rotation；Screw blade 10 during rotation, when effect of the screw blade 10 in spiral force when being contacted with ground of screw blade 10 Under will move down；Screw blade 10, which moves down, just will drive mounting shell 5 and moves down；Mounting shell 5 moves down will Fixed plate 9 is driven to move down；Fixed plate 9 move down just will drive triggering gear 12 move down；It is downward to trigger gear 12 Triggering gear 12 in mobile process under the action of 3 frictional force of support plate just can rotate；The triggering rotation of gear 12 will make Air motor 16 and extension spring 21 reach a stable state；Soil can be constantly transported to by screw blade 10 in the process On the upside of ground；During well-digging, if be crowded with soil between adjacent knife blades in the screw blade 10 of downside, circular knife Piece 10 just loses cutting power；I.e. screw blade 10 cannot continue to rotate down；It triggers between gear 12 and support plate 3 at this time In stationary state；That is triggering gear 12 stops operating；Air motor 16 stops working；Gas in air pressure telescopic link 4 is stretching It will reverse flow under the action of spring 21；That is 4 disequilibrium of extension spring 21 and air pressure telescopic link；At this time in extension spring 21 Under the action of, driving support plate 22 will move up；Driving support plate 22, which moves up, will make taper triggering block 1 upward It is mobile；Taper triggering block 1, which moves up, will make frizzen 8 move outward；The movement outward of frizzen 8 will to stretch Contracting swing rod 24 stretches；The extended length of i.e. flexible swing rod 24；At this time in the first swing rod 11, second swing rod 23, first rotating shaft 14 Under the action of the virtual bar and flexible swing rod 24 that the line of 19 axis of axis and the second shaft is constituted constitute double-crank mechanism, stretch The swing speed of contracting swing rod 24 will constantly change；That is the revolving speed of the second shaft 19 constantly changes；I.e. eight adjustings The velocity of rotation of eight connection shafts 44 in mechanism 56 also constantly changes；The rotation speed of axle sleeve 42 in eight regulating mechanisms 56 Degree also constantly variation；In this case, the axle sleeve 42 in eight regulating mechanisms 56 is being revolved with corresponding eight groups of arc drive blocks 43 Turn that difference will be subjected to displacement on direction；And axle sleeve 42 is fixed in corresponding connection shaft 44, will not be moved up and down；So eight groups Arc drive block 43 will be moved up and down relative to mounting shell 5；Eight groups of arc drive blocks 43 move up and down just will drive it is corresponding Eight installation drive rings 35 move up and down；Eight installation drive rings 35, which move up and down, just will drive screw blade 10 and moves up and down； Since the lower side of screw blade 10 is fixedly mounted on mounting shell 5；So the spiral in the moving process of screw blade 10 The screw pitch of blade 10 will change；And then the soil between adjacent knife blades on screw blade 10 is squeezed and stretched； So that the soil on screw blade 10 between adjacent knife blades becomes loose；And become loose soil in 10 spiral force of screw blade Under the action of will be discharged；If the soil on screw blade 10 between adjacent knife blades is excessively solid, it is difficult to clear up, at this time The resistance that the one section corresponding screw blade 10 excessively solid with soil on screw blade 10 is subject in a rotational direction will become Greatly；The rotary resistance of i.e. corresponding connection shaft 44 becomes larger；Positioned at downside in the regulating mechanism 56 of side i.e. disposed thereon The rotary resistance of outer tooth ring 49 becomes larger, and the rotary resistance of the 5th corresponding gear 47 will become larger；5th gear at this time 47, which just will drive corresponding swing shaft 58, swings；So that two the 5th gears 47 being mounted in the swing shaft 58 with it is corresponding Two the 6th gears 50 disengage；Being located at the flight on the downside of this section will stop moving in the up-down direction；That is circular knife Piece 10 is stuck；Screw blade 10 is lifted at this time；Well-digging can be improved by adjusting the screw pitch of screw blade 10 in the present invention The drilling depth of mechanism.
