Description

A kind of portable original-state soil sampler

Technical field

The utility model is related to soil sample technical field, and in particular to a kind of portable original-state soil sampler.

Background technology

Soil sample collector, disclosure satisfy that soil sample holostrome, equivalent, easily requires, be fertilization compositions based on earth measurement, soil prison The work of the clay fertilizers such as survey solves the problem for the accurate acquisition pedotheque being difficult to, convenient, quick and accurate acquisition soil-like Product, control sampling error to greatest extent, are fertilization compositions based on earth measurement, soil monitoring and Soil fertility investigation of cultivated land and quality evaluation project Soil sampling essential tool.

Existing soil sample collector uses T-shaped sampler, needs sampling thinking highly of straight downward in sampling, both hands hold Handle is rotated back and forth, and is pushed simultaneously, and firmly uniform, dynamics will be depending on the shearing strength of soil, to keep the nature of soil Situation, proposes sampler after sampler is pressed into soil depth enough below, sampler can take the soil sample got out of；But soil When earth is more dry, there may be fine soil grain to clog sampler in rotary course, cause out sample to have some setbacks, can be bonded in sampler.

When in use, there are some drawbacks in T-shaped sampler.On the one hand, in sampling, it is necessary to continuous rotating sampler ability Sampler is pressed into below ground, during pressing under rotation, the soil of sampling can be damaged, it is difficult to meet high accuracy The standard of sampling, in the experiment of high request, T-shaped sampler can bring test error in itself；On the other hand, by constantly rotating Sampler is pressed into soil and sampled, muscle power is very expended, for testing crew, the labor intensity of soil sample is larger.

Utility model content

The purpose of this utility model is to provide a kind of portable original-state soil sampler, and it is disposable by lever style handle Sampler is pressed into soil and completes sampling, earth Rotating fields will not be caused to destroy to soil to be sampled, sampling quality is high, and thick stick Bar structure is very laborsaving can be opened or close there is provided the support bar of levers support power, carried very convenient, solved existing T-shaped sampler can not high-accuracy sampling and the big technical problem of sampling labor intensity in technology.

To achieve the above object, the technical scheme that the utility model is used is：

A kind of portable original-state soil sampler, including fixed center axis, sampling spoon and handle, the fixed center axis Upper end is uniformly hinged with the axle sleeve that is provided with slided in three support bars, the fixed center axis, and the sampling spoon is fixed in The lower surface of the axle sleeve, the sampling spoon is hollow tubular, and the bottom inwall of the sampling spoon is short compared with outer wall and outside Wall smooth excessiveness forms the annular edge of a knife, and one end of the handle is hinged with the first pole and the to hold interval on end, the other end Two poles, first pole and the upper surface of the axle sleeve are affixed, and the other end and the 3rd pole of second pole are hinged, The other end of 3rd pole is hinged with the fixed center axis top, first pole, the second pole and the 3rd pole It is distributed on same vertical plane.

Further, the middle part of the fixed center axis opens up groove vertically.

Further, the movable end of the support bar has kink, and the kink is in the support bar relative to solid Centration axis open after can flat contact soil surface to be sampled, offer fixing hole on the kink.

Compared with prior art, the utility model has advantages below：

In the utility model, directly sampling spoon is vertically pressed into soil by lever style handle and completes fast sampling, Soil texture will not be interfered or destroyed, it is ensured that the original state of sampling soil, reach higher standard for manual sampling, accorded with Close the requirement of high-precision soil sample test；Using lever style handle, in sampling, compared with prior art in T-shaped sampler, more It is laborsaving, alleviate the labor intensity of testing crew；The support bar of support force is provided for lever and fixed center axis is hinged so that branch Strut can be opened or tightened up relative to fixed center axis, be carried and using being quite convenient to.

Further advantage of the present utility model, target and feature embody part by following explanation, and part will also pass through The research and practice of the present invention are understood by the person skilled in the art.

Brief description of the drawings

Fig. 1 is the utility model structural representation.

Fig. 2 is Figure 1A portions enlarged drawing.

Embodiment

In order that technological means, creation characteristic, reached purpose that the utility model is realized more understand and are easy to effect Understand, the utility model is further elaborated with reference to the accompanying drawings and detailed description：

As a kind of preferred embodiment of the present utility model, accompanying drawing 1 and accompanying drawing 2 are referred to：

In Fig. 1, a kind of portable original-state soil sampler, including fixed center axis 1, sampling spoon 4 and handle 8, it is described The upper end of fixed center axis 1 be uniformly hinged with slided in three support bars 2, the fixed center axis 1 be provided with axle sleeve 3, it is described Sampling spoon 4 is fixed in the lower surface of the axle sleeve 3, and the sampling spoon 4 is hollow tubular, the bottom of the sampling spoon 4 Inwall is short compared with outer wall and forms the annular edge of a knife to outer wall smooth excessiveness, and one end of the handle 8 is spaced to hold on end, the other end The first pole 7 and the second pole 5 are hinged with, first pole 7 and the upper surface of the axle sleeve 3 are affixed, second pole 5 The other end be hinged with the 3rd pole 10, the other end of the 3rd pole 10 is hinged with the top of fixed center axis 1, described First pole 7, the second pole 5 and the 3rd pole 10 are distributed on same vertical plane.

In such scheme, the middle part of the fixed center axis 1 opens up groove 9, the movable end tool of the support bar 2 vertically There is kink 6, the kink 6 can flat contact soil to be sampled after the support bar 2 is opened relative to fixed center axis 1 Fixing hole is offered on surface, the kink 6.

When carrying out soil sampling, three support bars 2 are opened first, then according to the position of the soil to be sampled of selection Put, sampling spoon 4 is directed at sample point, and support bar 2 is supported on the ground, sample collector can slam support bar 2 with pin Kink 6, can also be by the way that the hard objects such as screw rod or reinforcing bar be squeezed into soil from the fixing hole of kink 6 to consolidate Sampling spoon 4, is then pressed into soil by fixed whole brother's sampler by way of handle 8 is pushed, as needed prediction sampling Amount of soil enough after handle 8 is lifted up, so that the soil of sampling be taken out, complete whole sampling work；This programme Directly sampling spoon is vertically pressed into soil by lever style handle and completes fast sampling, soil texture will not be interfered Or destruction, it is ensured that the original state of sampling soil, higher standard for manual sampling has been reached, has met wanting for high-precision soil sample test Ask；Using lever style handle, in sampling, compared with prior art in T-shaped sampler, it is more laborsaving, alleviate testing crew Labor intensity；The support bar of support force is provided for lever and fixed center axis is hinged so that support bar can be relative to fixation Central shaft is opened or tightened up, and is carried and using being quite convenient to.

Finally illustrate, above example is only unrestricted to illustrate the technical solution of the utility model, although ginseng The utility model is described in detail according to preferred embodiment, it will be understood by those within the art that, can be to this The technical scheme of utility model is modified or equivalent substitution, without departing from the objective and model of technical solutions of the utility model Enclose, it all should cover among right of the present utility model.
