Abstract

The invention relates to a handheld shallow soil sample sampler which comprises a soil sampling sleeve and a soil sampling pipe installed in the soil sampling sleeve. The soil sampling pipe can be taken out of the soil sampling sleeve, and a soil sampling annular gap is formed between the soil sampling pipe and the soil sampling sleeve; the upper end of the soil sampling sleeve and the upper end of the soil sampling pipe are flushed with each other and then are internally and externally fixed with each other through a chunk, multiple teeth which are bent in the same circumferential direction are evenly distributed on the outer wall of the lower end of the soil sampling pipe, the center of the upper end of the soil sampling pipe is provided with a driving shaft through a connecting rod, and the upper end of the driving shaft is radially provided with a hand-operated rotating rod. According to the sampler, the internal-external soil sampling sleeve-soil sampling pipe structure is adopted, soil is sampled through the soil sampling annular gap formed between the soil sampling sleeve and the soil sampling pipe, a soil sample is packaged by rotating the bent teeth arranged at the lower end of the soil sampling pipe, therefore, the soil sample is effectively prevented from falling off, one-time soil sampling can be achieved, time and labor consumption in multi-time soil sampling is avoided, and the soil sampling efficiency is improved.

Description

Hand-held shallow-layer soil sample dispenser

Technical field

The present invention relates to technical field of geological exploration, particularly to Handheld soil dispenser.

Background technology

In geological exploration field, gathering earth sample and often commonly use soil sampler, the soil sampler currently mainly used is hand-held soil sampler, and it is exclusively used in shallow-layer and fetches earth, and geology top layer is carried out Preliminary detection, to judge whether to need to carry out deep soil sampling.Existing hand-held soil sampler, particularly mellow soil sampling, typically use the set that fetches earth, utilize the sleeve pipe of end to insert in soil, sleeve pipe remains with when extracting soil.The soil sampler of this structure, although its structure is simple, but the soil sample in sleeve pipe easily comes off, it is therefore desirable to repeatedly fetch earth, inefficient.

Summary of the invention

The technical problem to be solved in the present invention is to provide a kind of hand-held shallow-layer soil sample dispenser, effectively overcomes the shortcoming that soil extracting efficiency is low, reliability is the highest of above-mentioned tradition soil sampler.

In order to solve the problems referred to above, the present invention uses following scheme:

A kind of hand-held shallow-layer soil sample dispenser, including fetching earth set and be installed on the pipe that fetches earth fetched earth in set, the Guan Kecong that fetches earth fetches earth and takes out in set, fetching earth pipe and fetching earth overlap between with the annular space that fetches earth；Fetch earth after the upper end overlapped flushes with the upper end of the pipe that fetches earth and realize interior extenal fixation between the two by chuck, the lower end outer wall of pipe of fetching earth is evenly equipped with multiple curved tooth bent to same circumferencial direction, the upper end center of pipe of fetching earth is provided with drive shaft by connecting rod, and the upper end of drive shaft is radially provided with manual bull stick.

Further improvement as technique scheme: described chuck includes snap ring and is symmetrically arranged on the buckle of snap ring inwall, the internal diameter of snap ring is more than the external diameter of the set that fetches earth, and buckle is with being buckled in fetch earth set and the exterior bayonet slot of pipe upper end of fetching earth and inner card cage respectively.

Further improvement as technique scheme: the two ends of described manual bull stick are telescopic tube, and after the inside retraction of described telescopic tube, its outer end is completely disposed in described snap ring.

The method have technical effect that:

The soil sample dispenser of the present invention, it is suitable for shallow-layer soil sample to take, fetch earth inside and outside employing set and the tubular construction that fetches earth, the annular space that fetches earth between the two is utilized to fetch earth, and after being rotated by the curved tooth of lower end, earth sample is packaged, it is effectively prevented from earth sample and comes off, can realize disposably fetching earth, avoid that repeatedly fetches earth to take time and effort, improve soil extracting efficiency.

Detailed description of the invention

Below in conjunction with the accompanying drawings the detailed description of the invention of the present invention is described further.

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 fetch earth set 1 in the pipe 2 that fetches earth, fetch earth pipe 2 can from fetch earth set 1 take out, fetch earth pipe 2 and fetch earth set 1 between with the annular space 3 that fetches earth；Fetch earth after the upper end of set 1 flushes with the upper end of the pipe 2 that fetches earth and realize interior extenal fixation between the two by chuck 4, the lower end outer wall of pipe 2 of fetching earth is evenly equipped with multiple curved tooth 5 bent to same circumferencial direction, the upper end center of pipe 2 of fetching earth is provided with drive shaft 7 by connecting rod 6, and the upper end of drive shaft 7 is radially provided with manual bull stick 8.

As shown in Figure 1, Figure 3, in the present invention, chuck 4 includes snap ring 41 and is symmetrically arranged on the buckle 42 of snap ring 41 inwall, and the internal diameter of snap ring 41 is more than the external diameter of the set 1 that fetches earth, and buckle 42 is with being buckled in fetch earth set 1 and the exterior bayonet slot 421 of pipe 2 upper end of fetching earth and inner card cage 422 respectively.During use, chuck 4 is buckled in fetch earth set 1 and the upper end of the pipe 2 that fetches earth, firmly lower repoussage soil sampler is to after the layer that fetches earth, manual bull stick 8 is utilized to rotate the pipe 2 that fetches earth, utilize curved tooth 5 and relatively rotating between set 1 of fetching earth, the earth sample of lower end is encapsulated, it is to avoid earth sample comes off from the annular space 3 that fetches earth by original route.

As it is shown on figure 3, for convenience of chuck 4 Fast Installation in set 1 and pipe 2 upper end of fetching earth of fetching earth, the two ends of manual bull stick 8 are telescopic tube, and after the inside retraction of telescopic tube, its outer end is completely disposed in snap ring 41.

Embodiment provided above is the better embodiment of the present invention, only it is used for the convenient explanation present invention, not the present invention is made any pro forma restriction, any art has usually intellectual, if in the range of without departing from the carried technical characteristic of the present invention, utilize the Equivalent embodiments that the done local of disclosed technology contents is changed or modified, and without departing from the technical characteristic content of the present invention, all still fall within the range of the technology of the present invention feature.
