Description

Handheld Shallow Soil Sample Taker

technical field

The invention relates to the technical field of geological exploration, in particular to a hand-held soil fetcher.

Background technique

In the field of geological exploration, soil fetches are often used when collecting soil samples. At present, the soil fetches mainly used are hand-held soil fetches, which are specially used for shallow soil fetching, and preliminary detection of the geological surface to determine whether deep soil is needed. sampling. Existing hand-held soil fetchers, especially for loose soil sampling, generally adopt a soil-taking sleeve, and utilize the sleeve pipe at the end to insert into the soil, and retain soil in the sleeve pipe when pulled out. Although the soil extractor of this structure is simple in structure, the soil sample in the sleeve pipe is easy to come off, therefore needs to fetch soil repeatedly, and efficiency is not high.

Contents of the invention

The technical problem to be solved by the present invention is to provide a hand-held device for taking shallow soil samples, which effectively overcomes the shortcomings of low soil retrieval efficiency and low reliability of the above-mentioned traditional soil taking devices.

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

A hand-held device for taking shallow soil samples, including a soil-taking cover and a soil-taking pipe installed in the soil-taking cover, the soil-taking tube can be taken out from the soil-taking cover, and a soil-taking ring is provided between the soil-taking tube and the soil-taking cover gap; the upper end of the soil-absorbing sleeve is flush with the upper end of the soil-absorbing pipe, and the internal and external fixation between the two is realized by a chuck. The center is equipped with a drive shaft through a connecting rod, and the upper end of the drive shaft is radially equipped with a manual rotating rod.

As a further improvement of the above technical solution: the chuck includes a snap ring and a buckle symmetrically installed on the inner wall of the snap ring. The outer card slot and the inner card slot at the upper end of the soil pipe.

As a further improvement of the above technical solution: both ends of the manual rotating rod are telescopic tubes, and after the telescopic tube is retracted inwardly, its outer end is completely placed in the snap ring.

Technical effect of the present invention is:

The soil sample taker of the present invention is suitable for taking shallow soil samples. It adopts the inner and outer soil taking sleeves and the soil taking pipe structure, and uses the soil taking ring gap between the two to take soil, and rotates through the curved teeth at the lower end. The soil samples are packaged to effectively prevent the soil samples from falling off, realize one-time soil extraction, avoid time-consuming and labor-intensive multiple soil extraction, and improve the efficiency of soil extraction.

Detailed ways

The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

As shown in Fig. 1, Fig. 2 and Fig. 3, the hand-held shallow soil sample taker of the present embodiment comprises a soil-taking cover 1 and a soil-taking pipe 2 installed in the soil-taking cover 1, and the soil-taking pipe 2 can be obtained from the Taken out from the soil cover 1, there is a soil-absorbing annular gap 3 between the soil-absorbing pipe 2 and the soil-absorbing cover 1; the upper end of the soil-absorbing cover 1 is flush with the upper end of the soil-absorbing pipe 2, and the internal and external fixation between the two is realized by the chuck 4 The outer wall of the lower end of the soil-taking pipe 2 is evenly distributed with a plurality of curved teeth 5 bent in the same circumferential direction, the center of the upper end of the soil-taking pipe 2 is equipped with a drive shaft 7 through a connecting rod 6, and the upper end of the drive shaft 7 is installed radially. pole 8.

As shown in Figure 1 and Figure 3, among the present invention, the chuck 4 comprises a snap ring 41 and a buckle 42 symmetrically installed on the inner wall of the snap ring 41. There are outer clamping slots 421 and inner clamping slots 422 buckled on the upper ends of the soil-taking cover 1 and the soil-taking pipe 2 respectively. When in use, buckle the chuck 4 on the upper end of the soil-absorbing sleeve 1 and the soil-absorbing pipe 2, press down the entire earth-absorbing device to the soil-absorbing layer, use the manual rotating rod 8 to rotate the soil-absorbing pipe 2, and use the curved teeth 5 and the soil-absorbing sleeve 1, the soil samples at the lower end are packaged to prevent the soil samples from falling off from the soil taking annulus 3 according to the original path.

As shown in Figure 3, in order to facilitate the fast installation of the chuck 4 on the soil-taking sleeve 1 and the upper end of the soil-taking pipe 2, the two ends of the manual rotating rod 8 are telescopic tubes. Placed in the snap ring 41.

The above examples are preferred implementations of the present invention, and are only used to illustrate the present invention conveniently, and are not intended to limit the present invention in any form. Anyone with ordinary knowledge in the technical field, if they do not depart from the present invention, Within the scope of the technical features, the equivalent embodiments that make partial changes or modifications using the technical content disclosed in the present invention, and do not deviate from the technical features of the present invention, still belong to the scope of the technical features of the present invention.
