Abstract
The utility model discloses a combined soil sampler capable of realizing layered sampling. The sampler comprises a top cover, more than two barrel bodies and a sampling head, wherein the barrel bodies comprise an outer barrel and an inner barrel; the outer barrel is divided into two half bodies along the central axis; the inner barrel clings to the inner wall of the outer barrel; the two half bodies are integrally connected through a connecting fastener; the top cover is in threaded connection with the barrel bodies; the barrel bodies are in thread connection with each other; the barrel bodies are in threaded connection with the sampling head; the two parts in threaded connection with each other are fastened through a movable fastener; an air hole is formed in the top cover; and a horizontal rotary handle is arranged on the side wall of the top cover. According to the combined soil sampler, the plurality of detachable barrel bodies are combined, so that the pollution caused by contact between soil samples acquired for multiple times and the sampling barrel bodies and the sample loss and the pollution caused by transferring the samples to other containers from the barrel bodies are avoided; as the samples are cylindrically packaged in the sampling inner barrel, the long-period storage and the re-layering of the samples are made possible.
Description
Technical field
The utility model relates to the soil sampling technical field, is specifically related to a kind of combined type soil sampling thief and corollary apparatus thereof of realizing stratified sampling.
Background technology
Soil is the main research objects of occurring in nature for agricultural, environment, geology and biological study personnel.The collection of pedotheque is the basic work that the related researcher conducts a research.Particularly, along with the development of Environmental Protection in China cause, the soil environment Journal of Sex Research is increasingly sophisticated, also more and more higher for the requirement of the collection of soil information.Columnar soil sampler is to use a class soil collecting device comparatively widely at present.Known columnar soil sampler mainly comprises that complete column cylinder and integral type gouge bore two kinds.Be divided into again artificial collection and machinery collection on acquisition mode, the shortcoming that machinery gathers is that service condition is harsh, complicated operation.The columnar sampler of manual mode normally utilizes rotatable handle drive or make sampling thief vertically be inserted in soil with tension weight churning, and then pedotheque enters into sampling head, then soil sample collector directly enhanced from soil or take out sample head by rotating backward handle, finally from sampling head, sample being released.But, when columnar sampler is applied to when column soil sample that depth of soil is slightly large fetches earth all can't guarantee the accuracy of sampling depth, can not realize soil column sample collection.When taking out sample head, when sampling depth is larger, directly promote the more difficult realization of sample head, simple reverse rotation handle extracts easy damaged screw interface simultaneously.In addition, while from sampling head, taking out sample, sample can not easily be lost in moulding, and the sample transfer process is loaded down with trivial details, and sampling head easily causes mixing of sample room when repeatedly sampling, and change sample head, makes the sampling cost increase.And no matter be that complete column cylinder or integral type gouge brill sampling thief length are all long not portable.
The utility model content
For the defect of existing columnar soil sampler, the purpose of this utility model is to provide the column soil collecting device of the detachable combination of a kind of cylindrical shell.
A kind of combined type soil sampling thief of 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 the outer tube inner wall setting, and two halfbodies are connected by connection clip; Between top cover and cylindrical shell, all be threaded connection between each cylindrical shell and between cylindrical shell and sampling head, also fastening by movable button between above-mentioned two parts that are threaded connection; Described top cover is provided with pore, and top cover sidewall is provided with the swing handle of level.Handle is arranged on top cover the operation of being convenient to sampling thief; The air hole purpose is while preventing from gathering soil after the air seal compression, causes sampling thief to be difficult to gather fully.
Described urceolus lower end is provided with the end-blocking that prevents that inner core from gliding.
Above-mentioned sampling thief also comprises the capping with inner core upper and lower side coupling.After taking out sample, cover capping, be conducive to the preservation of sample.
Be provided with O-ring seal in described capping.
Described inner core is to be made by the lucifuge polythene material.
The utility model adopts detachable knockdown sampling cylindrical shell.Can realize by the cylindrical shell that configures different numbers the collecting soil sample of different depth.The top cover of sampling thief, each combined barrel and sampling head all are threaded connection, and after connecting, by the activity button-fold of each one, guarantee that like this screw thread can not opened when handle rotates.The transfer of pedotheque and the difficult problem of layering when the cylindrical shell of combined-disconnected has overcome complete cylindrical shell sampling thief sampling; Bore sampling thief for the integral type gouge, use the cylindrical shell of detachable combination, be equivalent to increase the quantity of sampling head, the sample contamination brought while making the efficiency of once sampling greatly strengthen also having avoided same place repeatedly to sample simultaneously; Because the length of each cylindrical shell is controlled, for gathering the cylindrical soil layering sample, overcome the accurately defect of layering of traditional sampling device.And relative traditional sampling device, the design of its detachable combination makes this sampling thief more convenient on carrying, and under easier lowered in field environment, uses.The utility model adopts the mode that lucifuge sample inner core is set in the sampling cylindrical shell to collect the sample of collection, when sampling thief is worked, sample directly enters the sample inner core, avoided contacting of sample and sampling urceolus, only needing to change the sample inner core while repeatedly using gets final product, make the transfer process of pedotheque more simplify, the pollution that while having avoided multi collect, pedotheque contact sampling cylindrical shell brings and sample loss and the pollution brought when cylindrical shell is transferred to other containers again, due to sample with cylindric be encapsulated in that long preservation that sampling makes sample in inner core is deposited and again layering realized may.And the design that simultaneously utilizes connection clip makes the sampling cylindrical shell can be easy to open and seal, and the sample inner core takes out also very convenient.The tygon material that the material of sample inner core is the black lucifuge.
