Problems solved by technology
[0002] At present, the spiral blades used in the drilling mechanism are all fixed on the rotating sleeve by welding. If the adjacent blades are filled with soil during the drilling process, the spiral blades in the drilling mechanism will lose their cutting ability; The spiral blade cannot continue to turn downward; if the spiral blade continues to turn downward when the adjacent blades are filled with soil, it may cause damage to the blade; the drilling mechanism cannot be used normally; it affects the progress and affects people's lives ; Therefore, it is very necessary to design a well drilling mechanism that can loosen the soil on the adjacent blades during the well drilling process

[0060]Specific embodiments: when people are using the drilling mechanism designed by the present invention, the drive motor 2 works, and the drive motor 2 will drive the first rotating shaft 14 to rotate; the rotation of the first rotating shaft 14 will drive the first pendulum 11 to rotate around the first A rotating shaft 14 axis rotates; the rotation of the first fork 11 will drive the second fork 23 to swing; the swing of the second fork 23 will drive the telescopic fork 24 to rotate around the axis of the second rotating shaft 19; It will drive the second rotating shaft 19 to rotate. In the initial state, the shortest length of the telescopic swing link 24 is the same as the length of the first swing link 11 . In this case, the fourth gear 38 will drive the installation shell 5 to rotate; the installation shell 5 rotates through the corresponding arc drive block 43 to drive the corresponding installation drive ring 35 to rotate; the installation drive ring 35 rotates to d...

The invention belongs to the technical field of well drilling mechanisms and particularly relates to a swing-rod-based well drilling mechanism with spiral blades variable in screw pitch. The well drilling mechanism comprises a support plate, a punching mechanism, a driving mechanism and a fixing plate. When people use the designed well drilling mechanism, if the gap between every two adjacent spiral blades on the lower side is filled with mud in a working process, the spiral blades lose the cutting capability, and that is to say that the spiral blades cannot continue to rotate downwards; at the moment, the length of the retractable swing rods is increased, and in this case, the spiral blades can move up and down, so that the mud between every two adjacent spiral blades is extruded and stretched and correspondingly becomes loose; the loose mud can be discharged under the action of the spiral force of the spiral blades. The well drilling depth of the well drilling mechanism can be increased by adjusting the screw pitch of the spiral blades.

If the adjacent blades are filled with soil during the drilling process, the spiral blades in the drilling mechanism will lose their cutting ability; The spiral blade cannot continue to turn downward; if the spiral blade continues to turn downward when the adjacent blades are filled with soil, it may cause damage to the blade; the drilling mechanism cannot be used normally; it affects the progress and affects people's lives ; So it is very necessary to design a well drilling mechanism that can loosen the soil on the adjacent blades during the well drilling process. [0003] The present invention designs a swing-rod-based helical blade pitch-v...
