When the inner-tube is full, a device called an overshot is lowered down the hole via a wireline cable and brought to the surface by use of a winch.
Once the inner-tube assembly is at the surface, an empty inner tube is lowered into the hole so drilling can resume.
A Overshot is available for each size of core barrel. This is the retrieval device lowered on the wireline to recover the inner tube assembly containing core.Wuxi Chin supplier BQ core barrel back end head assembly for surface wireline mining drilling

GEOTEC WUXI offer a complete line of single & double and triple tube core barrels, which will provide superior performance and obtain the full recovery of the sample in any application of diamond core drilling.
Using a wireline system , core is recovered quickly by retrieving the inner tube directly through the drill string. The rods remain in the hole until the bit needs to be replaced. this has big cost advantages when drilling deep holes for mineral exploration.
The core barrel assembly is composed of the inner-tube group and outer-tube group.
The inner-tube group collects the core samples during the drilling process and is independent of the outer-tube gourp.
The outer-tube gourp always remains at the buttom of the hole and houses the inner-tube group during the drilling process.
The standard wireline Double tube inner-tube gourp is composed of Head Assembly, Inner tube, Core lifter case , Core lifter, Stop ring.
The outer-tube group is composed of the remain of the core barrel components: Locking coupling, Adapter coupling, Outer-tube, Landing ring, Inner tube stabilizer.
Standard Wireline Double tube Core Barrels are ideal for use in most of the drilling conditions and are available for application in standard hole sizes( B,N,H,P).
