"螺旋钻井装置" can be translated into English as "auger drilling device" or "spiral drilling equipment".
"Auger" is a common term for a tool with a helical blade or shaft used for boring holes, which fits well with the description of a spiral drilling device.
"Spiral" directly refers to the helical or spiral shape of the drilling tool, and "drilling equipment" is a more general term for the machinery used in drilling operations.
Both translations are acceptable, depending on the specific context and the level of technicality desired. In more technical or industry-specific contexts, "auger drilling device" might be more commonly used.
