Summary of the invention
For the defect of existing columnar soil sampler, the object of this invention is to provide the column soil collecting device that a kind of cylindrical shell detachably combines.
A kind of combined type soil sampler realizing stratified sampling, this sampling thief comprises top cover, plural cylindrical shell and sampling head, and described cylindrical shell comprises urceolus and inner core, and urceolus is split as two halfbodies along axis, inner core is close to outer tube inner wall and is arranged, and two halfbodies are connected by connection clip; All be threaded connection between top cover and cylindrical shell, between each cylindrical shell and between cylindrical shell and sampling head, above by also fastening by movable button between two parts be threaded; Described top cover is provided with pore, and top cover sidewall is provided with the swing handle of level.Handle is arranged on operation top cover being convenient to sampling thief; Air hole object, after air seal compresses when preventing collection soil, causes sampling thief to be difficult to gather completely.
Described urceolus lower end is provided with the end-blocking preventing inner core from gliding.
Above-mentioned sampling thief also comprises the capping of mating with inner core upper and lower side.After taking out sample, cover capping, be conducive to the preservation of sample.
O-ring seal is provided with in described capping.
Described inner core is made up of lucifuge polythene material.
The present invention adopts detachable knockdown sampling cylindrical shell.The collecting soil sample of different depth can be realized by the cylindrical shell configuring different number.The top cover of sampling thief, each combined barrel and sampling head are all threaded connection, and by the activity button-fold in each portion after connection, ensure that screw thread can not be opened when handle rotates like this.The cylindrical shell of combined-disconnected overcomes the transfer of pedotheque and a difficult problem for layering when complete cylindrical shell sampling thief samples; For integral type half gouge drilling sample device, use the cylindrical shell of detachable combination, be equivalent to the quantity adding sampling head, make the efficiency of once sampling greatly strengthen the sample contamination brought when simultaneously it also avoid same place multiple repairing weld; Because the length of each cylindrical shell is controlled, for collection cylindrical soil layering sample, overcoming legacy sampler cannot the defect of accurate layering.And relative legacy sampler, the design of its detachable combination makes this sampling thief more convenient on carrying, and uses under easier lowered in field environment.The present invention adopts and arrange the mode of lucifuge sample inner core to collect the sample of collection in sampling cylindrical shell, when sampling thief works, sample directly enters sample inner core, avoid the contact of sample and sampling urceolus, only need when repeatedly using to change sample inner core, the transfer process of pedotheque is more simplified, the pollution that when avoiding multi collect, pedotheque contact sampling cylindrical shell brings and the sample loss brought when cylindrical shell transfers to other containers again and pollution, due to sample with cylindric be encapsulated in sampling inner core in make the long-term preservation of sample deposit and again secondary clearing achieve possibility.And utilizing the design of connection clip to make sampling cylindrical shell can be easy to open and close simultaneously, sample inner core takes out also very convenient.The material of sample inner core is the tygon material of black lucifuge.
