SAMPLE EXTRACTOR OF A SAMPLE WITHIN SAMPLING PIPE USED FOR DRILLING CORE

摘要

The present invention relates to a sample extruder to push out samples inside a sampling pipe applied to a drilling core in a given width and, more specifically, to a sample extruder of a sampling pipe for a drilling core wherein; samples stored inside a sampling pipe are pushed out easily in an accurate width and cut off with a cutting thread by installing a piston-shaped push head inserted into the sampling pipe at the front end of a screw shaft to push out the samples while moving the screw shaft forward and backward by rotating an operation handle or operating a screw motor; due to which not only accuracy and reliability of research and experimental data through samples may be greatly improved by acquiring most samples stored in the sampling pipe by a hygienic and safe method without contamination or damages as well as preventing unnecessary waste of samples; but also all processes from extrusion of samples through cutting of the samples may be automatically performed by additionally installing a sample cutter comprising; a feeding spool of the cutting thread, a cutting cylinder for moving the same upward and downward, a winding spool of the cutting thread, and a spool motor for driving the same at the front end side of the sampling pipe.
