Title: DIELECTRIC DRILLING HEAD FOR HORIZONTALLY DIRECTED DRILLING MACHINES
Abstract:
The invention relates to the field of pipeline construction by a horizontally directed drilling method. A drilling head comprises a housing provided with a front large end having a thread for connection of a drilling blade, a rear large end having a thread for connection of drilling rods, and a canister mounted in the housing. The canister is in the form of a housing provided with a front small end and a rear small end. The rear small end has a cover closing off a mounting seat of a probe placed into said canister. The canister consists of a power supply unit, a measuring unit, sensors, a processing unit and an antenna device. The front large end is provided with a thread for attaching the front small end and for fixing the canister in the housing of the drilling head. The drilling head housing and probe canister housing are manufactured from a high-strength, non-electrically-conductive dielectric material, wherein the walls of the housing are solid. An increase in the operating reliability and efficiency of a drilling head are achieved.
