Description
Technical field
The invention belongs to agricultural technology field, it is related to a kind of portable grade topsoil stratified sampler and its operation
Method.
Background technology
Natural radionuclide7Be tracer techniques effectively promote grinding for short-term and secondary rainfall soil erosion regular
Study carefully.It utilizes7Need to acquire upper soll layer layering sample when the Be tracer study soil erosions for establishing7The Soil profile function of Be and
Estimate Soil Erosion Rate, but7Be is distributed only within upper soll layer 2cm, it is desirable that every layer of acquisition thickness of layering sample is only 2-
3mm, thus fine upper soll layer stratified sampling technology for7The accuracy of the Be tracer soil erosions has a great impact.Mesh
With determine the sample boxes of area as previous, manual layering scraping or divided from top to bottom with the method for iron brush swipe soil in sample boxes
Layer acquisition topsoil, from top to bottom layering scraping or swipe sampling have the following problems：(1) manual layering scraping or swipe are adopted
Sample is difficult artificial control thickness to grade (2-3mm) layering, and scraping depth error is big so that inhomogeneities occurs in layering；(2)
Because original-state soil has caking property, underlying soil is disturbed while scraping or swipe from the top down, is caused mixed between different depth
It closes, influences to be layered accuracy；(3) scrape or brush with grade it is small from the soil particle of parent and very loose, it is difficult to from sample boxes
Middle whole quickly removes stripping soil particle, and is easy to disturbance or incidentally lower soil；(4) time-consuming and laborious, it almost needs to climb
It is careful on the ground bit by bit to scrape or swipe, taking-up in layer, workload are very big.In addition, existing dedicated layering is adopted
Sample device is all the lift height more than Centimeter Level, is seldom related to grade stratified sampling.Therefore scraping from top to bottom or brush
The method of sampling taken and existing stratified sampler cannot the accurately layering and error is larger on grade, cause accurately to retouch
It states7Distribution functions of the Be in upper soll layer section, and then influence7The accuracy of Be tracer result of calculations and7Be tracing methods
It is a wide range of to promote.

Miniature step is drawn on the top of upper fixed outer shroud 6 respectively, the mini-mesa on the top of the lower part of lower fixed outer shroud 5 and upper fixed outer shroud 6
The internal diameter of rank is equal to the internal diameter for the cutting ring 8 that fetches earth, and the internal diameter at 6 other positions of the lower part of lower fixed outer shroud 5 and upper fixed outer shroud is bigger
In the outer diameter for the cutting ring 8 that fetches earth, the cutting ring 8 that fetches earth is stuck between fixed outer shroud 6 and the miniature step of lower fixed outer shroud 5, cuts soil
There is handle of a knife on 9 both sides of knife, and the length and width of blade part is both greater than the diameter of upper fixed outer shroud 6.
The operating method of portable grade topsoil stratified sampler of the present invention, includes the following steps：It is adopting
Cradling piece 1, fixed disc 2, soil-shifting plectane 4 and lower fixed outer shroud 5 are assembled before sample, and soil-shifting plectane 4 is rotated into lower fixed outer shroud 5
It is interior；Then native cutting ring 8 will be taken to be pressed into according to cutting ring sampling method in soil and equal with ground, will then be dug out with spade, with cutting
Native knife 9 scabbles lower part, and the cutting ring 8 that will fetch earth gently is put into lower fixed outer shroud 5, adjusts the cutting ring 8 that makes to fetch earth of soil-shifting plectane 4 and is stuck in down
On miniature step in fixed outer shroud 5, upper fixed outer shroud 6 is sleeved on and fetches earth on cutting ring 8 and consolidates with the lower screw 7 of fixed outer shroud 5
It is fixed, gently rotate anti-push rod 3 so that soil-shifting plectane 4 the native face in the cutting ring 8 that fetches earth is shifted onto it is equal with 6 top of upper fixed outer shroud,
Then according to the thickness of layering and thread away from, determine the turnning circle of anti-push rod 3, it is tight with native knife 9 is cut after reaching required thickness
It sticks 6 top of fixed outer shroud and firmly quickly cuts native layering.
Beneficial effects of the present invention：
The present invention designs a kind of portable grade topsoil stratified sampler, with thread away from for standard control hierarchy
Thickness, changes tradition method of layering scraping soil from top to bottom in sample boxes, and use is counter from the bottom up to be pushed away and from top
The thinking for taking layering is cut, lift height is accurately controlled, difference interlayer interferes with each other when substantially eliminating sampling, time saving and energy saving, this is adopted
Sample device is easy to operate, easy to use, overcomes defect existing for traditional surface layer grade stratified sampling.
