Description

Sampler

Technical field

The utility model is related to geology sampling instrument, and in particular to a kind of sampler.

Background technology

Soil sampler is used for lifting lower floor's experiment undisturbed soil soil as sample to understand its property, to make more to understand base Layer property, soil as former state will be taken in higher depth, extension bar, referred to as soil sampler are saved therefore, Jia one in the middle part of soil sampler sometimes.When using By soil sampler cutting ring pierce in soil to need depth after soil sampler is extracted, cutting ring and semicircular cylinder are pulled down afterwards, use scraper The soil unnecessary soil in soil sampler two ends scraped off in equating, cutting ring can be as experiment style.

Application No. CN201620735313.6 Chinese utility model patent disclose it is a kind of be easy to collect it is plug-type Soil sampler, the soil sampler completes to fetch earth by rotating handles, is released the soil of taking-up using ejector dozer after taking, but this fetches earth Device, which is used, belongs to fixed gripping, it is impossible to relatively deep insertion soil sample so that each amount of fetching earth is limited, and cutting ring on be provided with and take Soil box so that fetch earth easily unrestrained, success rate is not high.

Utility model content

To solve problem above, the utility model is achieved through the following technical solutions：

A kind of sampler, includes the closure of drilling rod, the cutting ring of drilling rod one end and the other end, and the closure is provided with unidirectional Steam vent, the drilling rod is provided with impact structure, close to cutting ring on hollow cylindrical cavity, the drilling rod close to the position of closure Position provided with fetching earth groove.

The impact structure includes being arranged on moving back on the drilling rod and bores stress step and enter to bore stress step, described to move back brill Stress step and enter to bore hand-held sliding sleeve is provided between stress step, the hand-held sliding sleeve is slided up and down along drilling rod to be impacted to stress step Realize into brill, move back brill.

Slide assemblies are also cased with around the groove that fetches earth, the slide assemblies, which are enclosed on drilling rod, to slidably reciprocate and slide assemblies two A sealing ring is respectively equipped with the madial wall at end, for ensure drilling rod internal cavity sealing, the slide assemblies two ends it is close The distance between seal is more than the length for the groove that fetches earth.

Be located at the impact structure for the stability for the drilling rod in sampling process of ensureing to fetch earth, on the drilling rod and fetch earth groove it Between provided be flexibly connected support frame.

To ensure that cutting ring produces the active force inwardly compressed to soil sample into after brill, the cutting ring is loudspeaker tubular.

Operation principle：Radial rotary end sealing lid, with below the hand with strength impact of slide downward hand-held sliding sleeve enter to bore by Power step, under the drive of impulsive force, cutting ring enters hard stratum, due to the design of loudspeaker tubular cutting ring, and soil can be caused in drilling rod Extruding is received when descending becomes even closer, when moving back brill, moves back brill stress step above the hand-held sliding sleeve impact of upward sliding, now The air that internal cavity is extruded is excluded by one-way vent, forms negative pressure, and soil will not fall off when taking out drilling rod；Move back after brill By pulling slide assemblies, the soil of sampling is taken out from the groove that fetches earth, in addition, it is necessary to explanation, during fetching earth, Slide Group Part, which is completely covered, to fetch earth groove and keeps the sealing of drilling rod intracavitary by sealing ring.

Beneficial effect

The utility model is inhaled relative to traditional soil sampler using the impact structure and negative pressure not occurred in the prior art The effect taken, while optimizing the structure of cutting ring and the groove that fetches earth, also ensures that the process of fetching earth is not trickled down while the increase amount of fetching earth Hack, investigates work for geology and provides a kind of reliable, practical sampling tool.

Fig. 3 is sampler internal chamber schematic diagram.

Reference is as follows：

1：Drilling rod, 2：Cutting ring, 3：Closure, 4:One-way vent, 5：Impact structure, 6：Fetch earth groove, and 7：Move back brill weighted table Rank, 8：Enter to bore stress step, 9：Hand-held sliding sleeve, 10：Slide assemblies, 11：Sealing ring, 12：Support frame.

Embodiment

The utility model is described in further detail with reference to the accompanying drawings and examples, it will be appreciated that this practicality is new The structure of type is not limited in following examples：

As Figure 1-3, a kind of sampler, includes the closure 3 of drilling rod 1, the cutting ring 2 of drilling rod one end and the other end, should Closure 3 is provided with one-way vent 4, and the drilling rod 1 is close to the position of closure 3 on hollow cylindrical cavity, the drilling rod 1 Provided with impact structure 5, close to the position of cutting ring 2 provided with the groove 6 that fetches earth.

More specifically, the impact structure 5 include being arranged on the drilling rod 1 moving back brill stress step 7 and enter to bore by Power step 8, described to move back brill stress step 7 and enter to bore to be provided between stress step 8 hand-held sliding sleeve 9, the hand-held sliding sleeve 9 is along drilling rod 1 Slide up and down and the impact of stress step 7,8 is realized into brill, brill is moved back.

It is more preferred, slide assemblies 10 are also cased with around the groove 6 that fetches earth, the slide assemblies 10 are enclosed on drilling rod 1 Return and slide and be respectively equipped with a sealing ring 11 on the madial wall at slide assemblies two ends, to ensure the sealing of drilling rod internal cavity, The distance between the sealing ring 11 at the slide assemblies two ends is more than the length for the groove 6 that fetches earth.

It is more preferred, for the stability for the drilling rod 1 in sampling process of ensureing to fetch earth, it is located at the impact knot on the drilling rod Provided with the support frame 12 being flexibly connected between structure 5 and the groove 6 that fetches earth.

More preferred, to ensure that cutting ring 2 produces the active force inwardly compressed to soil sample into after brill, the cutting ring 2 is loudspeaker Tubular.

Operation principle：Radial rotary end sealing lid, exerted oneself with hand below the impact of slide downward hand-held sliding sleeve enter to bore by Power step, under the drive of impulsive force, cutting ring enters hard stratum, due to the design of loudspeaker tubular cutting ring, and soil can be caused in drilling rod Being squeezed when descending becomes even closer, when moving back brill, moves back brill stress step above the hand-held sliding sleeve impact of upward sliding, now The air that internal cavity is extruded is excluded by one-way vent, forms negative pressure, and soil will not fall off when taking out drilling rod；Move back after brill By pulling slide assemblies, the soil of sampling is taken out from the groove that fetches earth, in addition, it is necessary to explanation, during fetching earth, Slide Group Part, which is completely covered, to fetch earth groove and keeps the sealing of drilling rod intracavitary by sealing ring.

General principle of the present utility model and principal character and advantage of the present utility model has been shown and described above.Ability The technology people in domain is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification Simply illustrate principle of the present utility model, on the premise of the utility model spirit and scope are not departed from, the utility model can also There are various changes and modifications, these changes and improvements are both fallen within the range of claimed the utility model.The utility model will Protection domain is sought by appended claims and its equivalent thereof.
