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 digging mechanisms, and particularly relates to a well digging mechanism provided with screw blades with the variable screw pitch. The well diggingmechanism 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 the screw blades located on the lower side are jammed with soil, the screw blades lose the cutting ability, namely the screw blades cannot continue rotating downwards; and at this time, a third gear moves upwards and is finally engaged with a second gear, 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.
