Description

A kind of simple and fast original position drawing out soil equipment for Soil K+adsorption

Technical field

A kind of simple and fast original position drawing out soil equipment is the utility model is related to, more particularly, to a kind of letter for Soil K+adsorption Easy quick in situ drawing out soil equipment, belong to agricultural soil detection sampling instrument field.

Background technology

Soil is that crop obtains high-quality, high yield and efficient important foundation in agricultural production, and it is to soil to obtain pedotheque Earth carries out the premise of assay, particularly to obtain the soil body of original state shape, and the collection of the original state soil body affect soil nutrient, Element and the accuracy and science of the physicochemical character research work such as unit weight and porosity.The acquisition of pedotheque at present is mainly By taking soil sample, or but it is existing take simple conventional tool of the soil sample device using similar shovel sample, or using it is more complicated, , many deficiencies in soil sample acquisition process be present in the not portable improved instrument that fetches earth of electronic or original state portable.Tradition takes The sample instrument depth randomness that fetches earth is very big, and soil sample amount is very big, causes quality of soil sample representative poor, sample is unbalanced；It is and modern The instrument of fetching earth of type improvement type has that complicated, parts are more, heavier-weight, not portable, and sampling operation is less efficient, and The problems such as expensive, cause improvement type instrument application of fetching earth not extensive.Therefore, it is above-mentioned based on existing in existing sampling technique Technical problem defect, it is necessary to improve equipment, design a kind of simple, quick, accurate and labour-saving drawing out soil equipment and be sampled.

Utility model content

For problem and defect be present in above-mentioned, the purpose of this utility model is to provide a kind of letter for Soil K+adsorption Easy quick in situ drawing out soil equipment, the quick accurate taking-up original state shape soil body can be achieved.

To achieve the above object, the utility model employs following technical scheme：

A kind of simple and fast original position drawing out soil equipment for Soil K+adsorption, it is characterised in that including crossbeam, the U-shaped set that fetches earth Manage and go out core, the crossbeam includes symmetrical cross bar and the middle perforation that left and right is set；The U-shaped sleeve pipe that fetches earth is angular column Shape, simultaneously open sky, upper end is connected with the perforation on crossbeam, lower end to fetch earth mouth, it is described go out core be one can be along the U-shaped set that fetches earth Movement that pipe slides up and down is unearthed mechanism, it is described go out core includes the knob at top, middle cylindricality is unearthed bar, bottom Soil outlet, the unearthed bar pass through the perforation at crossbeam center, are enclosed in U-shaped fetch earth in sleeve pipe.

Further, for the mouth that fetches earth of the U-shaped sleeve bottom that fetches earth for wedge shape, it is also wedge shape to go out core bottom soil outlet.U Type, which fetches earth, sleeve pipe and to be gone out the tapered end of core and is respectively provided with inclined-plane, is more convenient for fetching earth, is served labour-saving effect.

Further, it is described go out core bottom set V-type be unearthed screening glass, the V-type be unearthed screening glass and soil outlet it is anti- Button is connected.Go out core and the unearthed screening glass of V-type is set, it is ensured that the integrality that soil sample is extracted in the U-shaped sleeve pipe that fetches earth.

Further, it is described it is U-shaped fetch earth its lower end housing outer surface from wedge shape is portalled set from lower to upper There is scale.Drawing out soil equipment will carried out due to setting scale on the outside of the U-shaped sleeve bottom that fetches earth in the U-shaped sleeve pipe insertion soil that fetches earth It is topsoil premise base in soil sample when ensureing that the U-shaped sleeve pipe height that fetches earth is suitable with arable layer thickness during soil sampling On plinth, the pedotheque of different depth can be conveniently extracted, facilitates the analysis of different soil sample, quality of soil sample is not only representative It is good, and different soil sample is accurate.

Compared with prior art, the utility model production cost is low, practical, sampling method is simple, it is quick, conveniently have Effect, the soil sample sample quality taken is balanced, and integrality is good, is adapted to the Physico-chemical tests analysis of different soil sample.

Brief description of the drawings
