Abstract
The invention provides a soil bulk density sampler and a sampling method, for solving the problem that an existing sampler generates vibration and makes soil stocky in a sampling process. The soil sampler comprises a barrel and an auxiliary barrel which are arranged in a mutual sleeving manner, a hand shank for operating is in threaded connection with the top of the barrel, the lower end face of the auxiliary barrel is provided with a saw-toothed burrowing structure, a spiral protuberance extending upwards and spirally from the burrowing structure is arranged on the outer surface of the auxiliary barrel, and the upper part of the auxiliary barrel is provided with an operating handle and an upper end cover and a lower end cover for blocking the upper and lower ends of the barrel after sampling. A sampling method is also disclosed. The device and the method change the traditional manner of sampling through smashing down a sledgehammer, and perform sampling in a more flexibly spirally burrowing manner, so that the sampled soil layer is more real; meanwhile, the method is simpler that one person can complete the operation.
Description
Technical field
This scheme relates to a kind of device and sampling method of soil weight sampling, belongs to sampling equipment technical field.
Background technology
The collection of soil weight sample is a basic steps of soil investigation, for mensuration and the analysis of pedotheque lays the first stone.So the collection of sample has very strict requirement, the general vertical sampling method that adopts samples, and common sampler is an apparatus cylindraceous, comprises cutting ring and handle, both are splits, as shown in Figure 1, in the upper end of cylindrical shell, be provided with the portion of impacting, by impacting of hammer, make cylinder-shaped cutting ring part vertically be inserted in soil, form test power, then in the surrounding of cylindrical shell, excavate, and cutting ring is taken out, complete a sampling operation.During due to arid, soil plough sole is too hard, and surrounding excavation is more difficult; On long term experiment surrounding excavation area, too large impact is tested later; The upper cover of cutting ring is consolidation too, is difficult for taking off.Strictly speaking, in soil sample process, guarantee the virgin state of soil, and use hammer to impact, can make the soil of inner barrel produce vibration with stocky, so can affect the accuracy of sample, therefore be necessary to improve.
Summary of the invention
In order to solve the deficiencies in the prior art, the invention provides a kind of soil weight sampler, for solving vibration and the stocky problem that existing sampler sampling process produces, it is a kind of high-precision sampler, simultaneously, be convenient to test and taking-up, simplify procedures, introduce a kind of method that applicable this apparatus samples simultaneously.
The technical solution adopted for the present invention to solve the technical problems is:
A soil sample collector, is characterized in that, comprises
One cylindrical shell cylindraceous, described cylindrical shell is the straight tube that upper and lower diameter is identical, is threaded connection the handle of connection one for operating at the top of described cylindrical shell,
One can be enclosed within the auxiliary cylindrical shell in described cylindrical shell outside, in the lower surface of described auxiliary cylindrical shell, be provided with jagged plane soil structure, at the outside surface of described auxiliary cylindrical shell, be provided with from digging the soil structure spiral protrusion of spiral extension that makes progress, and be provided with operating handle on the top of described auxiliary cylindrical shell
And the upper end cover and the bottom end cover that the top and bottom of cylindrical shell are carried out shutoff after sampling.
Further, described spiral protrusion is double helix.
Further, described spiral protrusion upper surface is provided with groove.
Further, described cylindrical shell and auxiliary cylindrical shell are all stainless steel cylinder.
Further, the sawtooth in described plane soil structure is spiral fashion in one plane not.
Further, the surfaces externally and internally of described cylindrical shell and auxiliary cylindrical shell is all smooth surface, and is provided with cutting edge in cylindrical shell lower port.
Further, the real wall end cap of described upper end cover for being threaded with cylindrical shell, described bottom end cover is the hollow out end cap being fastened and connected with cylindrical shell.
Further, on the connection cover of described handle bottom, be provided with air hole.
Use above-mentioned sampler to carry out the method for soil weight sampling, it is characterized in that, comprise the steps:
Step 1, is nested with cylindrical shell and auxiliary cylindrical shell be placed on sampling spot ground,
Step 2, pins on the other hand the handle of cylindrical shell upper end, and the operating handle that another hand rotates on auxiliary cylindrical shell is holed auxiliary cylindrical shell downwards, and presses down handle portion and make cylindrical shell follow-up, until cylindrical shell is absorbed in soil completely,
Step 3, the surface dust of cleaning cylindrical shell surrounding, and take off auxiliary cylindrical shell, then left-right and front-back rocks cylindrical shell gently, and cylindrical shell is upwards mentioned, and then cylindrical shell is taken off on handle, and uses upper and lower end cap to seal cylindrical shell.
The invention has the beneficial effects as follows:
1, simple in structure, only have two parts, manufacture and easy to use is easy to carry simultaneously, meets the needs that field occasion is used.
2, changed the mode of pounding sampling under traditional use sledgehammer, adopted more flexible spiral to dig native mode and sample, sampling soil layer is truer, and meanwhile, usability methods is simpler, single can operation.
3, after certain depth, after assisting cylindrical shell to take out, in the periphery of cylindrical shell, can form a gap, conveniently mention cylindrical shell and soil sample, and what form is a regular cylindric dark hole, substantially do not affect the sampling of next level.
