AI Technical Summary

Technical Problem

When existing rock drilling equipment encounters hard rock layers, it is easy to cause the drilling rod to get stuck under stress, affecting the drilling efficiency, and it is difficult to move the drilling rod to crush the rock layer.

Method used

A rock formation drilling equipment for geological exploration is designed, using a motor-driven spline shaft and drill rod structure. The axial lifting and power-driven tapping mechanism of the spline shaft is driven, so that the drill bit can effectively crush the rock formation through tapping action when encountering a hard rock formation.

Benefits of technology

It solves the problem of drill bit stuck when traditional equipment encounters hard rock layers, improves drilling efficiency, and realizes flexible movement of drill rods and precise control of different depths.

Abstract

The rock stratum drilling equipment for geological exploration comprises a base fixedly supported on the ground through an external support, one side of the base is fixedly connected with an n-shaped frame, movable grooves are formed in the symmetrical positions of the two sides of the n-shaped frame, and the inner walls of the movable grooves in the two sides are movably connected with movable blocks which do lifting reciprocating motion; a fixed plate is fixedly connected to one side of the movable block, a spline shaft driven by a power mechanism to rotate is connected to the fixed plate in a penetrating and fixed-axis rotating mode, the outer contour of the bottom end of the spline shaft is sleeved with a drill rod conducting lifting reciprocating motion, and a drill bit conducting drilling is fixedly connected to the bottom end of the drill rod. A through hole allowing the drill bit to move for drilling is formed in the position, corresponding to the drill bit, of the base, a knocking mechanism for driving the drill rod to do lifting reciprocating motion is arranged on the fixing plate, the drill rod is moved to smash a rock stratum, and the drilling efficiency is improved.
