Embodiment 1
A kind of ground water soil layer sampler, as shown in Figure 1, being the structural representation of ground water soil layer sampler of the invention
Figure, as shown in Fig. 2, be the use state diagram of ground water soil layer sampler of the invention, it includes: push rod 2, is lived at handle 3
Stopper rod 4, sampling exocoel 5, reset spring 8, sliding block 9 and sampler barrel 12.
Sample and be symmetrically arranged on the side wall of exocoel 5: sliding chamber 10, piston rod 4 are threaded through in sliding chamber 10, and bottom end is fixed to be connected
Sliding block 9 is connect, sliding block 9 is adapted with sliding chamber 10, can be along sliding 10 inner wall of chamber sliding.4 top of piston rod is fixedly connected with handle 3.
Sampling exocoel 5 has perforative cavity, and sampler barrel 12 is slidably connected in the cavity, and fixes and connect with handle 3
It connects.Sampler barrel 12 has perforative sampling inner cavity, is successively arranged from top to bottom on the inner wall of the sampling inner cavity: pressing plate 6 and baffle
15, the pressing plate 6 and baffle 15 are adapted with sampling inner cavity, and baffle 15 is fixedly connected with the inner wall for sampling inner cavity, pressing plate 6 with take
The inner wall of sample inner cavity is slidably connected.
Push rod 2 sequentially passes through handle 3, pressing plate 6 and baffle 15, is pierced by from the bottom of sampler barrel 12, even with 3 activity of handle
It connects, top is fixedly connected with limit plate 1 (can be connected through a screw thread, on the one hand may be implemented to fix, on the other hand realize removable
Unload), bottom end is equipped with: conical structure.
Be respectively and fixedly provided on pressing plate 6 and the opposite face of baffle 15: connecting plate 7, push rod 2 are passed through from connecting plate 7, with connecting plate
7 are flexibly connected.Reset spring 8 is nested on push rod 2, and its both ends is fixedly connected on two connecting plates 7, is resetted by setting
The elastic force of spring 8 may be implemented push rod 2 and be automatically moved up, and drives conical structure deformation closure, prevents soil from falling.
As shown in figure 3, being the structural schematic diagram of conical structure of the invention, above-mentioned conical structure includes: Ruo Ganshou
Contracting umbrella leaf 11, several connecting rods 17, connection ring 14 and cone insertion head.Connection ring 14 is nested on the side wall of push rod 2 and lives
Dynamic connection, in the top of connection ring 14, be further fixed on the side wall of push rod 2: stop collar 13 is used to limit connection ring 14
Position prevents contraction 11 hypersystole of umbrella leaf from damaging to umbrella leaf.It shrinks and passes through connecting rod 17 between umbrella leaf 11 and connection ring 14
Connection, the both ends of connecting rod 17 are separately fixed on the edge for shrinking umbrella leaf 11 and connection ring 14.Shrinking umbrella leaf 11 is sector, if
Dry shrink umbrella leaf 11 (fan-shaped) is rotatably connected on the edge of cone insertion head, and the edge for shrinking umbrella leaf 11 is equipped with: close
Packing 16, one of both sides edge for shrinking umbrella leaf are equipped with grafting step, remaining contraction umbrella leaf is equipped with grafting on one side
The edge of step, and two neighboring contraction umbrella leaf, a contraction umbrella leaf fits with another grafting step, guarantees to shrink umbrella leaf
11 with sample in cavity wall fit closely, prevent soil from falling and result in the need for resampling, avoid waste of time.Specifically
Ground shrinks umbrella leaf 11 and connecting rod 17 settable 4, and the length for shrinking umbrella leaf 11 is to sample the half of intracavity diameter.It is strutting
When state, 11 drops down of umbrella leaf is shunk, several contraction umbrella leaves 11 form a circular flat, realize the closure of sampler barrel 12,
Prevent soil from falling.
Wherein, the surface for sampling exocoel 5, sampler barrel 12, baffle 15, push rod 2, conical structure and stop collar 13 is all provided with
Have: ceramic coating.Specifically, exocoel 5, sampler barrel 12, baffle 15, push rod 2, conical structure and stop collar 13 is sampled to adopt
With metal material, it is equipped with ceramic coating in metal surface, to avoid metallic element is mixed into soil sample.
The top of push rod 2 is equipped with internal screw thread.The sampler also includes: extension rod is threaded in the top of push rod 2,
It can be used for taking the soil sample of different depth so that sampler of the invention has different length by the extension rod of different length.
The working principle of ground water soil layer sampler of the invention, specific as follows:
When in use, handle 3 is pushed down on, handle 3 drives sampler barrel 12 to move down, while piston rod 4 pushes sliding block 9
It is moved in sliding chamber 10, the design of the piston rod 4, sliding block 9 and sliding chamber 10, which is played, had not only been able to achieve support but also energy to sampler barrel 12
Realize the function of opposite sliding.
During being inserted into soil, push down on push rod 2, under the action of soil upward pressure, shrink umbrella leaf 11 to
Upper contraction is conducive to insertion soil in cone, and makes sampler barrel 12 in open shape.Stop connection ring 14 by stop collar 13
Upward sliding prevents contraction 11 hypersystole of umbrella leaf from damaging to umbrella leaf.
Since soil is lax in ground water soil layer, soil enters in sampler barrel 12 by 12 bottom of sampler barrel to be collected, and is unclamped
After push rod 2, under the elastic force effect of reset spring 8,2 automatic returning of push rod can be made in situ, drive and shrink the rising of umbrella leaf 11, by
Contraction 11 drops down of umbrella leaf is closed to sampler barrel 12 in the downward pressure of soil in sampler barrel 12, prevents soil from falling
It falls.
After push down on push rod 2 after taking out in soil, push rod 2 is moved down, so that shrinking umbrella leaf 11 far from sampler barrel 12
The soil sample of acquisition is released, can carry out soil layer composition test by bottom.Since the surface that sampler of the invention is contacted with soil sample is equal
Equipped with ceramic coating, avoids and be mixed into metallic element in soil sample.
When in use, according to the depth for taking soil layer, it can choose the extension rod for being threadedly coupled different length, as shown in Figure 4.
It is discussed in detail although the contents of the present invention have passed through above preferred embodiment, but it should be appreciated that above-mentioned
Description is not considered as limitation of the present invention.After those skilled in the art have read above content, for of the invention
A variety of modifications and substitutions all will be apparent.Therefore, protection scope of the present invention should be limited to the appended claims.
