Description
Technical field
The present invention relates to agrology experimental study apparatus fields, can be used simultaneously multiple cutting rings more particularly, to one kind and sample
Autosampler.
Background technique
Soil cutting ring is usually used in measuring some soil such as the soil weight, moisture content, density, porosity, water characteristic curve
Characteristic plays key player in the research of agrology.Common cutting ring is mainly the annulus of metal material, and volume is general
It is divided into 100cm3And 200cm3Two kinds.Cutting ring is driven into soil currently, normal soil foil sampler mainly passes through hammer,
Then cutting ring is taken out, carries out analysis and experiment.The method of this soil sample is larger to original-state soil disturbance in the presence of hammering, takes
When it is laborious, land destruction area is larger, and depth takes when soil that there are cutting rings to be not easy the problems such as taking out.
Although there is while taking the foil sampler of two pedotheques at present, this foil sampler drill bit is ring
Sword construction, drill bit bores downwards move sampling process it is very laborious, bring inconvenience to sampling process.What the present invention designed fills with driving
The Autosampler and sawtooth drill bit set can make sampling process greatly save manpower, and present apparatus convenient disassembly, be suitable for field
It installs and uses.
Summary of the invention
The present invention devises a kind of Autosampler that can be used simultaneously multiple cutting ring samplings, solves following technology and asks
Topic.
(1) it rotates foil sampler by manpower in the prior art to be sampled, drill bit bores downwards dynamic sampling process very
Arduously, such mode makes sampling efficiency low, also result in be easy after technical staff's long-time use it is tired out.
(2) prior art is sampled different depth soil by single cutting ring, and process repeats, is cumbersome and existing
Foil sampler drill bit is ring sword construction, so that sampling process is more laborious, is brought inconvenience to sampling.
(3) it can guarantee the accuracy of sampling using fixed bracket, but soil is splash during bit, so that mud
Soil sticks on fixed rack inner wall, is easily accessible in card slot after soil attachment is excessive, so that soil sample is contaminated, finally
Cause measured value to be distorted, thus needs often to be purged fixed rack inner wall soil.
