Description

A kind of Portable soil sampler

Technical field

This utility model relates to a kind of sampler, especially with regard to a kind of Portable soil sampler.

Background technology

Soil sample collector is the important basic instrument for research of agricultural sciences such as soil measurement formula, farmland quality lifting and contaminated soil improvement, the science of soil sample can directly affect the accuracy of the result of study such as Soil structure analysis, soil inner material distribution, and soil sample collector is the required instrument of collecting soil sample.

In the research of agricultural sciences such as soil measurement formula, the lifting of farmland quality and contaminated soil improvement, often use soil sample collector, soil is carried out sampling, chemical examination and the analysis of necessity. But existing soil sample collector there is problems in that (1) sampling sample storage process operation is loaded down with trivial details, and existing soil sample collector generally only possesses sampled functions, without storing pedotheque function, take out and need after soil special to scrape soil working tool, pedotheque is scraped from soil sample collector, for cohesive soil, operation is wasted time and energy; (2) inconvenience is carried, owing to existing soil sample collector volume is big, quality big, so going out to carry inconvenience; (3) sample storage bag cracky in storage and transportation process, existing soil sample storage is generally adopted Self-enclosing sample sack, but in transportation, owing to mutually extruding and jolting, it is easy to that breakage occurs, cause that sample pollutes mutually, so the physicochemical property such as structure that can not keep original pedotheque; (4) price is high, and existing soil sample collector price is typically in hundreds of and not etc., does not generally require to thousands of and buy more soil sample collector if needing to gather a large amount of pedotheque in a short time, cause spend higher.

Summary of the invention

For the problems referred to above, the purpose of this utility model is to provide a kind of Portable soil sampler simple to operate and easy to use.

For achieving the above object, this utility model takes techniques below scheme: a kind of Portable soil sampler, it is characterized in that: it includes one handle, one end of an elastic jump ring it is fastenedly connected at the middle part of described handle, the other end of described jump ring connects one end of a probe tube by two bearing pins, the other end detachably connected of the described probe tube cutting ring for fetching earth.

Described probe tube is plastic tube, is respectively arranged with scale value on the surfaces externally and internally of described probe tube tube wall.

Described cutting ring is zigzag cutting ring.

Described seal member is the sealing shroud of one end closing, one end open.

Described jump ring is arranged to swallow-tail form or door shape.

This utility model is owing to taking above technical scheme, it has the advantage that 1, this utility model arranges one handle, one end of an elastic jump ring it is fastenedly connected at the middle part of handle, the other end of jump ring connects one end of a probe tube by two bearing pins, the other end detachably connected one of the probe tube cutting ring for fetching earth, this utility model simple in construction, easy to use, easy to carry, good economy performance. 2, this utility model probe tube is plastic tube, is respectively arranged with scale value on the surfaces externally and internally of probe tube tube wall, it is simple to obtain taken sample exactly when sampling, it is to avoid waste. 3, this utility model cutting ring is zigzag cutting ring, in order to cutting ring inserts in the soil needing sampling. 4, this utility model at probe tube two ends detachably connected two seal members, seal member has elasticity, it is simple to closure probe tube.

Detailed description of the invention

Below in conjunction with drawings and Examples, this utility model is described in detail.

As shown in Figure 1 and Figure 2, the utility model proposes a kind of Portable soil sampler, it includes one handle 1, one end of an elastic jump ring 2 it is fastenedly connected at the middle part of handle 1, the other end of jump ring 2 connects one end of a probe tube 3 by two bearing pins 21, the other end detachably connected of probe tube 3 cutting ring 31 for fetching earth.

This utility model also includes two for blocking the seal member 4 at probe tube 3 two ends, and seal member 4 can be specifically the sealing shroud (as shown in Figure 3) of one end closing, one end open, is enclosed within the end of probe tube 3 during use. Seal member 4 has elasticity, it is possible to adopt rubber to make.

In above-described embodiment, as Figure 1 and Figure 4, probe tube 3 is plastic tube, is respectively arranged with scale value on the surfaces externally and internally of probe tube 3 tube wall. Cutting ring 31 is zigzag cutting ring, in order to cutting ring 31 inserts in the soil needing sampling.

In above-described embodiment, as shown in Figure 1 and Figure 2, jump ring 2 is arranged to swallow-tail form or door shape.

As shown in Figure 1, this utility model is in use, first handle 1, jump ring 2 and probe tube 3 are separated, by the cutting edge of cutting ring 31 and the soil vertical needing sampling, hold and rotating down pressing probe tube 3 or knock probe tube 3 with weight, the bottom driving probe tube 3 is stretched in soil and is sampled, until the soil in probe tube 3 reaches desirable value. Then handle 1, jump ring 2 are connected by bearing pin 21 with probe tube 3, handle 1 in rotation, probe tube 3 are extracted realization from soil and fetches earth. After having sampled, being separated with probe tube 3 by jump ring 2, two seal members 4 are blocked at the two ends (as shown in Figure 5) of probe tube 3 by elastic deformation, it is possible to realize storage sample.

The various embodiments described above are merely to illustrate this utility model; wherein the structure of each parts, connected mode etc. all can be varied from; every equivalents carried out on the basis of technical solutions of the utility model and improvement, all should not get rid of outside protection domain of the present utility model.
