Description
Technical field
The invention belongs to a kind of soil sample instrument, be specifically related to a kind of portable semi-automatic rotary undisturbed soil sampler, be specially adapted to the sampling of farmland tillaging layer and inferior topsoil original-state soil.
Background technology
The all requirements of the research of pedology and related work thereof, the collection of pedotheque must be representative, otherwise the income analysis data have just lost using value.The sampling of mistake may cause full of prunes conclusion, even the unusual standard and accurately of concrete analysis operation.Therefore, in this sense, Sampling techniques are keys of soil investigation.The sampling method of standard is that the fetch earth degree of depth and the weight (when taking a sample in the open air mainly with volume controlled) of each sampled point is answered uniformity, and the ratio of soil sample the upper and lower is also identical.The basic demand of gathering undisturbed soil sample is that the maintenance soil sample is a virgin state, or soil sample is subjected to disturbance in allowed band.In fact it is impossible will obtaining not to be subjected to the soil sample of disturbance fully, because under state of nature, the internal stress of arbitrary particle all is a balance in the soil body, as soil sample is taken out from the soil body, then because of having eliminated the pressure of soil sample surrounding soil, stress condition changes, even the destruction of existing cohesive strength between particle occurs, and original structure must change.Therefore, should take measures to avoid soil sample to suffer disturbance and destruction.Obtain the undisturbed soil sample near natural structure, key is to improve sampling technique and uses advanced sampler.Selecting suitable soil sample collector or instrument, is the first step of having gathered soil sample.Yet, the structure of existing soil sample collector or instrument is very simple, (the upper end band cross bar of certain diameter and height is as manually rotating and making pressure downwards as spade, hoe, cutting ring (stainless-steel tube of a certain diameter and an end band blade highly), earth boring auger, one end band blade and confess the groove of soil), complicated (outer tube is as cutter head and the pedestal union body for the hammering position for the structure of triple tube sampler, it is the support of stopple coupon that middle tube is fixed on the pedestal, and inner tube is the sampling pipe of soil).They have following shortcoming more, are difficult to satisfy standardization undisturbed soil sample sampling requirement:
1, sampling thief or the instrument mode of burying are that hammering or people are the method that is pressed into.
2, sampling thief or instrument are difficult for grasping perpendicular to ground, and the degree of depth of burying is uncontrollable, and the degree of depth that fetches earth of each sampling point is consistent inadequately like this, and sample representativeness is just poor.
3, soil sample collector or instrument go deep into and break away from the pedotheque process, cause the extruding and the disturbance of different soil, can't guarantee the weight of the ecological niche of soil sample original state and pedotheque representative.
4, time-consuming, effort, unpowered device, inefficiency.
5, sampling technique is difficult to standard.The fetch earth degree of depth and the weight of each sampled point (when taking a sample in the open air mainly with volume controlled) can not uniformity, and the ratio of soil sample the upper and lower also is difficult to identical.So the result comparison that different sampling persons draw is poor.
Summary of the invention
Present situation quantitative to the agricultural soil original state at present in order to solve, the portable automanual sampler vacancy of depthkeeping degree, overcome existing soil sample collector and instrument is time-consuming, effort, unpowered device inefficiency, institute's soil space structure representativeness of adopting is not strong, at soil sample collector or instrument deeply and break away from the pedotheque process, cause the extruding and the disturbance of different soil, can't guarantee the weight of the ecological niche of soil sample original state and pedotheque representative, influence the researcher the accuracy of research object and the problems such as evaluation of authenticity.Overcome the standardization that existing soil sample collector and instrument can not be unified the soil acquisition method, reduce the problems such as interference of human factor sample representativeness.The present invention will provide a kind of portable semi-automatic rotary undisturbed soil sampler, and standard soil sample technology the time can be reduced to minimum with the interference to soil in sampling, obtain undisturbed soil sample near natural structure with assurance.Also can be used as the standardization sampler that disturbed soil sample is gathered.
The scheme of finishing the foregoing invention task is: portable semi-automatic rotary undisturbed soil sampler, be provided with stopple coupon, it is characterized in that, also be provided with the matrix of the T type structure of longitudinal axis hollow, described stopple coupon is fixed on the matrix of T type structure of this longitudinal axis hollow, simultaneously, on this matrix rotary power unit is installed, rotary power unit connects by non-concentric shafts gear train and hollow boring bit; The diameter of hollow boring bit is greater than described stopple coupon, and is arranged on outside the stopple coupon with one heart.
The matrix of the T type structure of described longitudinal axis hollow is the carrier of rotary power unit and hollow boring bit, is the immobilizing foundation that does not rotate when guaranteeing the stopple coupon sampling;
Described rotary power unit and hollow boring bit connect by non-concentric shafts gear train;
Be built-in with by being installed in the stopple coupon on the base shaft at hollow boring bit.Owing to be provided with bearing between hollow boring bit and the matrix, matrix and stopple coupon can not followed the hollow boring bit rotation; When hollow boring bit pierces soil, matrix is brought into soil with stopple coupon.
During use, rotary power unit drives hollow boring bit rotation incision, and the drive stopple coupon descends, in the process of incision, stopple coupon and institute's soil sampling do not have gyration, keep stablizing the incision state, after switching to the predetermined depth of soil sample down, mention sampler, institute's soil sampling can be removed with stopple coupon, is undisturbed soil thereby the guarantor levies the soil sample of being gathered.
The present invention has following prioritization scheme:
1, is provided with reducing gear in the gear train of rotary power unit and hollow boring bit;
2, described rotary power unit is provided with rechargeable battery as power source;
3, on the T type structural matrix table top level meter is housed;
4, matrix hollow axle center is together with the mobile ruler that can measure the soil sample significant height of adopting is arranged in the stopple coupon.
The present invention can satisfy the peak demand of gathering undisturbed soil according to original-state soil sample collecting characteristics and requirement, can satisfy the soil sampling technology of standard again.Designed a portable semi-automatic rotary undisturbed soil sampler that integrates multiple function, this design the time will be reduced to minimum to the interference of soil in sampling, obtain undisturbed soil sample near natural structure with assurance.This sampler is laborsaving, save time, simple for structure, easy to use, be easy to carry about with one, operation semi-automation is easy to popularize, and is particularly useful for the agricultural land soil original state sampling, as many with and can be used as standardization, standardized sampling instrument.The present invention provides semi-automatic soil sampling instrument for researchs such as pedology, ecology, geology, environmental sciences.
