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

The invention belongs to the technical field of well drilling mechanisms, and particularly relates to a spiral blade pitch variable well drilling mechanism which comprises a support plate, a punchingmechanism, a driving mechanism and a fixing plate. When people use the well drilling mechanism, if adjacent spiral blades on the lower side are filled with mud during the working process, the spiral blades lose the cutting capability, that is, the spiral blades cannot continue to rotate downward; at this time, a third gear moves upward to be meshed with a second gear finally; in this case, the spiral blades move up and down to extrude and stretch the mud between the adjacent spiral blades and loosen the mud between the adjacent spiral blades; the loose mud can be discharged under the spiral force of the spiral blades. The well drilling depth of the well drilling mechanism can be increased by adjusting the pitch of the spiral blades.
Description
Technical field [0001] The invention belongs to the technical field of well-drilling mechanisms, in particular to a well-drilling mechanism with variable helical blade pitch. Background technique [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 ; 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 well-drilling mechanism with variable helical blade pitch to...
