Description

technical field [0001] The invention relates to the technical field of mining equipment, in particular to an auger drill rod with high toughness, large diameter and wide fins. Background technique [0002] The large-diameter wide-fin auger drill pipe is a commonly used drill pipe in mining equipment. It is used to connect the surface equipment of the drilling rig with the drilling and grinding equipment or the bottom hole device at the bottom of the drilling well. The purpose of the large-diameter wide-fin auger drill pipe is to transfer the drilling mud Transported to the drill bit, and together with the drill bit to raise, lower or rotate the bottom hole device, so the large diameter wide fin helical drill pipe must be able to withstand huge internal and external pressure and lateral force, due to the influence of drilling depth and pressure, the large diameter wide The finned auger drill pipe often protrudes to a long depth during use, and a small force in the lateral dir...
