Abstract

The present invention is one well drilling machine including winder and frame. The present invention features that there are movable impact tube connected to the lower end of the hanging ring of the winder steel cable, movable shaft matched with the impact tube, chuck in the upper end of the shaft, balance weight in the lower end of the shaft, planing and grasping shovel connected via push rod tothe shaft, and impact shovel fixed to the lower end of the balance weight. During drilling well, the machine can drop tube while drilling.

Description

technical field [0001] The invention belongs to a well-drilling machine tool, in particular to a punching, grabbing, shoveling, and planing cone-head drilling machine tool. Background technique [0002] In the known technology, the function of the drilling tool is single. During the drilling operation, especially the caisson operation that needs to be lowered, due to the influence of the soil structure, the well wall cannot be solidified in time due to collapse, which affects the drilling efficiency. Contents of the invention [0003] The purpose of the present invention is to provide a kind of multi-functional operation, and can run while digging a well, and the punching, shoveling and planing cone-head well drilling machine with large hole diameter and deep well depth. [0004] The present invention adopts the following technical contents. [0005] Punching, shoveling, shoveling, cone-head drilling equipment, including a hoist, a frame, and a movable impact cylinder co...
