Electric geological core drilling rig

Abstract

The invention discloses an electric geological core drilling rig. The electric geological core drilling rig comprises a bracket, a power mechanism and a drilling mechanism, wherein the bracket comprises a supporting framework, a motor bracket and a lifting handle; the motor bracket is arranged on the supporting framework in a sleeving mode; the lifting handle is arranged on the motor bracket; an illuminating lamp is arranged on the supporting framework; anti-sliding teeth are arranged on the bottom of the supporting framework; the power mechanism comprises a current converter, a motor controller, a motor and a drill rod chuck; the motor is fixed on the motor bracket; the drilling mechanism comprises a drill rod and a drill bit; the drill bit comprises a drill bit steel body, a tool bit and a connecting layer; the tool bit is connected with the drill bit steel body by virtue of the connecting layer; and the lower end surface of the tool bit is a lip surface of the tool bit; and the lip surface is in the shape of a step which is internally low and externally high. The electric geological core drilling rig adopts the motor as a power source, is small in noise, does not generate tail gas and is beneficial for body health of an operator.

Description

technical field [0001] The invention relates to the technical field of geological survey, in particular to an electric geological core drilling machine. Background technique [0002] During geological surveying, in order to obtain soil samples, it is necessary to use a core drilling rig to drill holes in the surveyed area for sampling. Existing shallow core drilling rigs have the advantages of small structure, light weight, high efficiency and convenient operation, but they are generally driven by gasoline engines. When working, they not only need to carry a large amount of gasoline, but also generate noise and exhaust gas during work. Hazard to operator's health. In addition, the cutter head of the core drilling rig adopts a flat lip surface, which is not conducive to centering and guiding when drilling. Continuous drilling may easily cause the hole to be inclined, which will affect the sampling work. Contents of the invention [0003] The purpose of the present inventi...
