Hand-held shallow-layer soil sample dispenser
Technical field
The present invention relates to technical field of geological exploration, more particularly to Handheld soil dispenser.
Background technology
In geological exploration field, acquisition earth sample commonly uses soil sampler often, and the soil sampler mainly used at present is hand
Formula soil sampler is held, shallow-layer is exclusively used in and fetches earth, Preliminary detection is carried out to geology surface layer, to judge whether to need to carry out deep soil
Sampling.Existing hand-held soil sampler, especially mellow soil sample, and generally use fetch earth set, and soil is inserted into using the casing of end
In earth, soil is remained in casing when extraction.The soil sampler of this structure, although structure is simple, the soil sample in casing is held
It is easy to fall off, it is therefore desirable to repeatedly fetch earth, it is inefficient.
Invention content
The technical problem to be solved in the present invention is to provide a kind of hand-held shallow-layer soil sample dispensers, effectively overcome above-mentioned
The disadvantage that the soil extracting efficiency of traditional soil sampler is low, reliability is not high.
To solve the above-mentioned problems, the present invention uses following scheme:
A kind of hand-held shallow-layer soil sample dispenser, including fetch earth set and the pipe that fetches earth that is installed in fetch earth set, the pipe that fetches earth can
It takes out, is fetched earth between pipe and fetch earth set with the annular space that fetches earth from fetch earth set;The upper end of fetch earth set is flushed with the upper end for the pipe that fetches earth
Inside and outside fixation between the two is realized by chuck afterwards, the lower end outer wall of the pipe that fetches earth is evenly equipped with multiple to be bent to same circumferencial direction
The upper end center of curved tooth, the pipe that fetches earth is equipped with drive shaft by connecting rod, and the upper end radially installed of drive shaft has manual bull stick.
As a further improvement of the above technical scheme:The chuck includes snap ring and the card for being symmetrically arranged on snap ring inner wall
Button, the internal diameter of snap ring are more than the outer diameter of fetch earth set, and buckle with being buckled in fetch earth set and the exterior bayonet slot for pipe upper end of fetching earth and interior respectively
Card slot.
As a further improvement of the above technical scheme:The both ends of the manual bull stick are telescopic tube, described to stretch
After the inside retraction of the draw, outer end is completely disposed in the snap ring.
The technical effects of the invention are that:
The soil sample dispenser of the present invention is suitble to shallow-layer soil sample to take, using inside and outside fetch earth set and the pipe structure that fetches earth, utilizes two
The annular space that fetches earth between person fetches earth, and is packaged to earth sample after being rotated by the curved tooth of lower end, is effectively prevented from soil
Sample falls off, it can be achieved that disposably fetching earth, and avoid repeatedly fetching earth takes time and effort, and improves soil extracting efficiency.

Specific implementation mode
The specific implementation mode of the present invention is described further below in conjunction with the accompanying drawings.
As shown in Figure 1, Figure 2 and Figure 3, the hand-held shallow-layer soil sample dispenser of the present embodiment, including fetch earth set 1 and be installed on
The pipe 2 that fetches earth in fetch earth set 1, the pipe 2 that fetches earth can take out from fetch earth set 1, fetch earth between pipe 2 and fetch earth set 1 with the annular space that fetches earth
3;Inside and outside fixation between the two by chuck 4 is realized in the upper end of fetch earth set 1 after being flushed with the upper end for the pipe 2 that fetches earth, and fetches earth under pipe 2
End outer wall is evenly equipped with multiple curved teeth 5 bent to same circumferencial direction, and the upper end center for the pipe 2 that fetches earth is equipped with drive by connecting rod 6
The upper end radially installed of moving axis 7, drive shaft 7 has manual bull stick 8.
As shown in Figure 1, Figure 3, chuck 4 includes snap ring 41 and is symmetrically arranged on the buckle 42 of 41 inner wall of snap ring in the present invention,
The internal diameter of snap ring 41 is more than the outer diameter of fetch earth set 1, and buckle 42 carries and is buckled in fetch earth set 1 respectively and the exterior bayonet slot for 2 upper end of pipe of fetching earth
421 and inner card cage 422.In use, chuck 4 is buckled in fetch earth set 1 and the upper end for the pipe 2 that fetches earth, entire soil sampler is firmly pushed extremely
It fetches earth after layer, the pipe 2 that fetches earth is rotated using manual bull stick 8, using the relative rotation between curved tooth 5 and fetch earth set 1, by the soil of lower end
Sample encapsulates, and earth sample is avoided to fall off from the annular space 3 that fetches earth by original route.
As shown in figure 3, equal in fetch earth set 1 and 2 upper end of pipe of fetching earth, the both ends of manual bull stick 8 for convenience of 4 Fast Installation of chuck
For telescopic tube, after the inside retraction of telescopic tube, outer end is completely disposed in snap ring 41.
Embodiment provided above is the better embodiment of the present invention, only is used for facilitating illustrating the present invention, not to this hair
It is bright to make any form of restriction, any those of ordinary skill in the art, if not departing from the put forward skill of the present invention
In the range of art feature, using the equivalent embodiment locally changed or modified made by disclosed technology contents, and
Without departing from the technical feature content of the present invention, in the range of still falling within the technology of the present invention feature.
