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] DETAILED DESCRIPTION: When people use the well-drilling mechanism designed in the present invention, the driving motor 2 works, and the driving motor 2 will drive the first rotating shaft 14 to rotate; the rotation of the first rotating shaft 14 will drive the first swing rod 11 around the The axis of a shaft 14 rotates; the rotation of the first pendulum rod 11 will drive the second pendulum rod 23 to swing; the swing of the second pendulum rod 23 will drive the telescopic pendulum rod 24 to rotate around the axis of the second 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 mounting housing 5 to rotate; the mounting housing 5 will rotate through the corresponding arc-shaped drive block 43 to drive the corresponding mounting drive ring 35 to rotate; the mounting drive ring 35 will ...

The invention belongs to the technical field of well digging mechanisms, and particularly relates to a well digging mechanism. The well digging mechanism comprises a supporting plate, a punching mechanism, a driving mechanism and a fixing plate. When people use the designed well digging mechanism, in the working process, if adjacent blade bodies in screw blades located on the lower side are jammedwith soil, the screw blades lose the cutting ability, namely the screw blades cannot continue rotating downwards; and at this time, the length of a telescopic swinging rod is increased, in this case,the screw blades move up and down, thus the soil between the adjacent blade bodies on the screw blades is extruded and stretched, the soil between the adjacent blade bodies on the screw blades is loosened accordingly, and the loosened soil is discharged under the screw force effect of the screw blades. The well digging depth of the well digging mechanism can be increased by adjusting the screw pitch of the screw blades.
Description
Technical field [0001] The invention belongs to the technical field of well-drilling mechanisms, and particularly relates to a well-drilling mechanism. Background technique [0002] The spiral blades currently used in the drilling mechanism are all fixed to the rotating sleeve by welding. If the adjacent blades are packed with soil during the drilling process, the spiral blade in the drilling mechanism will lose the cutting ability; that is, The spiral blade cannot continue to rotate downward; if the spiral blade continues to rotate downward when the adjacent blades are filled with soil, the blade may be damaged; the well drilling mechanism cannot be used normally; the progress is affected and people's lives are affected ; 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. [0003] The invention designs a well drilling mechanism to solve the above problems. Summary of the invention ...
