Description
Technical field
The utility model relates to the sample devices of a kind of geologic prospecting and ambient soil monitoring, relates in particular to a kind of soil sampling head that keeps the soil original traits.
Background technology
In geologic prospecting, ambient soil monitoring and scientific research, teaching practice, often to investigate and research and analyse field soil.During operation, at first need gather different depth original-state soil sample, carry out test analysis then through the soil sampling head.Existing soil sampling head; Comprise that mainly pipe shape sampling pipe reaches and the pipe shape drill bit of its flexible connection; Sampling pipe is all identical with internal diameter, the external diameter of drill bit; The drawback of this structure is to make sampling pipe tube wall and the institute frictional resistance that fetches earth between earth big and make in the sampling tube chamber and between the soil extruding and compacting take place; Change the virgin state of soil inevitably, can not satisfy the original state property and the representativeness of geologic prospecting, ambient soil monitoring and scientific research, the desired soil natural structural profile of teaching practice and pedotheque.In addition, because the squeezing action of soil and sampling pipe tube wall, cause soil to bond on it; When especially taking a sample; Have sampling pipe now or release pedotheque from top to bottom, or on sampling pipe, establish open type sample tap not with cover, from sampling suitable for reading through piston plate; All be easy to make the virgin state of pedotheque to be damaged the accuracy of impact analysis.
The utility model content
The purpose of the utility model is to the problems referred to above; On existing soil sampling header structure basis, improve; Provide a kind of can reduce the sampling pipe inwall and fetch earth frictional resistance and cohesive force between earth; Prevent soil compression, and make the soil sampling head of the maintenance soil original traits that pedotheque is easy to take out, finally guarantee the accuracy of soil analysis research.
The utility model solves the technical scheme that its technical matters adopted:
A kind of soil sampling head that keeps the soil original traits comprises that pipe shape sampling pipe reaches and the pipe shape drill bit with same outer diameter as of its flexible connection, it is characterized in that said sample tube inner diameter is than the big 2-10mm of drill bit internal diameter.
Said drill bit and sampling pipe are for being threaded, and the connecting portion inwall of drill bit is arranged to the internal diameter transition with the smooth connection of sampling pipe inwall.
Said sampling pipe is provided with top cover, is arranged to removable semicircle pipe side cover by the semicircle pipe sidewall along the axis rip cutting of top cover bottom surface to sampling pipe bottom, and the opening body after this semicircle pipe side cover and sampling pipe are removed it is connected so that surfaces externally and internally is concordant.
Said semicircle pipe side cover forms surfaces externally and internally concordant whole-sample pipe with the shoulder structure socket of the corresponding setting in opening lower edge of sampling pipe opening body to inserting through the shoulder structure tongue that is provided with in its bottom; Semicircle pipe side cover inside upper part is dull and stereotyped perpendicular to the location that the sampling pipe axis fixedly installs a band pin-and-hole, and the top cover of said sampling pipe is provided with the latch via hole, and semicircle pipe side cover is through inserting the latch locking of the dull and stereotyped pin-and-hole in location via the latch via hole.
Said drill bit lower end is all tooth-shape structures of ring.
The beneficial effect of the utility model is: the sample tube inner diameter of the soil sampling head that (1) provides is than the big 2-10mm of drill bit internal diameter.When carrying out the drilling operation, soil gets into sampling pipe through the drill bit cutting, because of the sampling pipe caliber enlarges; Frictional resistance reduces; Avoided the sampling pipe inwall and fetch earth between the earth and the inner soil of sampling pipe between extruding, prevent compacting, therefore can keep the soil virgin state; (2) pedotheque of adopting can not be bonded in the sampling pipe inwall because of extruding; Being beneficial to original state takes out; Satisfy the original state property and the representativeness of geologic prospecting, ambient soil monitoring and scientific research, the desired soil natural structural profile of teaching practice and pedotheque, guarantee the accuracy that soil testing is analyzed.
