Anti-freezing drill-holding drilling equipment for drilling in frozen soil

Drilling equipment for drilling in frozen soil and preventing drilling from being blocked by freezing comprises a drilling device, an internal sleeve is arranged in a drill rod of the drilling device, an electric heating wire is wound on the internal sleeve, the drill rod and a drilling machine of the drilling device are connected through an adapter substitute, a supporting seat used for supporting the internal sleeve is arranged on the adapter substitute, and a wire is reserved at an insulating joint of the adapter substitute. And the extension end of the lower part of the conversion joint provides an external power supply channel for the heating wire. According to the drilling equipment for drilling in the frozen soil and preventing the drill from being blocked due to freezing, after the drill blocking condition caused by freezing occurs, the electric heating wire is used for heating, surrounding frozen water and sand can be rapidly melted, after the water and sand flow out of the slag discharging opening,
