The guide wheel of wire rope on frame that volume is put on the above-mentioned cable drum hangs down, and the end connects a suspension hook, and this suspension hook and weight removably connect; The below of weight suspention is vertical corresponding with coring drill rod, and the higher authorities of coring drill rod connect the anvil head, and following of coring drill rod connects soil sampler.

Above-mentioned soil sampler is a back cover sleeve-shaped parts up, the inwall of sleeve pipe is equipped with first from top to bottom successively and gets core bushing pipe, second and get core bushing pipe, the 3rd and get the core bushing pipe, the upper end of sleeve pipe is a joint, the bottom inwall that its top has air vent, sleeve pipe has internal thread, and the steel loop identical with an external diameter be threaded, and the bottom of steel loop sharply is a cutting ring shape.

The utility model is compared the beneficial effect that has with existing conventional art:

1, deep layer is got the core mode and is adopted the spiral method of creeping into to hole earlier to desired depth, and the special soil sampler that changes the outfit then carries out tension weight churning and gets the mode of core and carry out deep layer and get core.Institute's core of getting has reduced the disturbance of bore operation to original soil near the original soil state, has avoided the change to soil body in place density and water content.

2, the used soil sampler of the utility model is simple in structure, easy to use, reduces drilling through the disturbance of operation to getting core as far as possible

3, lifting feed mechanism of the present utility model, spiral drilling machine promote feeding and the coaxial supply of weight lifting required drive, and are distributed by electromagnetic clutch.This drive system structure compactness, easy and simple to handle, solved first auger boring, the back problem of getting system's conversion in the core process of impacting.

The utility model adopts the spiral method of creeping into to hole to desired depth, the special soil sampler that changes the outfit then carries out tension weight churning and gets the deep layer of core and get the core mode, can and original soil not had under disturbance (or the few disturbance) situation and get core at certain depth of stratum, realize the rapid drilling operation, prevent that Yin Luji from rolling or ramming construction quality defectives such as unreal, underground utilities and other underground structure based process be improper and causing surface settlement.The deep layer soil matrix degree of compaction that can be used for road and other building detects sampling.
