Problems solved by technology
Existing soil extractors can only sample one point at a time when sampling. When sampling, the sampling rod is rotated and screwed into the ground to extract samples. The disadvantage is that it is impossible to sample the surrounding area of the sampling point at the same time, and multiple sampling is required, and its efficiency is low.

Embodiment Construction
[0016] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.
[0017] Such as figure 1 As shown, the base structure of the soil fetcher of this embodiment includes a base body, and the base body includes a support ring 1 of a circular structure. The center of the support ring 1 is equipped with a guide shaft 3, and there is a gap between the guide shaft 3 and the support ring 1. A plurality of connecting rods 2 are connected; the upper surface of the supporting ring 1 has a plurality of thinning grooves 11 consistent with the number of the connecting rods 2, and the thinning grooves 11 are provided with guide holes 12 penetrating through the supporting ring 1. Just above the hole 12 is provided with a support plate 5, the support plate 5 is fixedly connected with the base body by means of a support rod, and the support plate 5 is provided with a guide bush 6; The support rod 4 and the second support ...

The invention relates to a base structure of a soil sampler. The base structure comprises a base body comprising a support ring adopting an annular structure, wherein a mounting guide shaft is arranged in the center of the support ring; a plurality of connecting rods are connected between the mounting guide shaft and the support ring; a plurality of thinning grooves with the same number as the connecting rods are formed in an upper surface of the support ring; guide holes penetrating through the support ring are formed in the thinning grooves; support plates are arranged over the guide holes and fixedly connected with the base body by virtue of support rods; guide shaft sleeves are arranged on the support plates. The base structure is simple in structure and reasonable in design; the base body adopts an annular structure and is compact in structure and small in occupied space; the triangular support rod structures are arranged, so that the base structure is high in stability and unlikely to deform.
Description
technical field [0001] The invention relates to the field of geological prospecting equipment, in particular to an earth taker. Background technique [0002] In the field of geological prospecting, earth-borrowers are often used when collecting soil samples. Existing soil extractors can only sample one point at a time when sampling. When sampling, the sampling rod is rotated and screwed into the ground to extract samples. [0003] On the same day, the applicant applied for a patent titled "Base Structure of Soil Taker", which solved the above problems. Among them, the base used to install multiple sampling rods is its key component, and the reasonable design of its structure determines the work of the soil taker. reliability and stability. Contents of the invention [0004] In view of the above-mentioned shortcomings in the existing prior art, the applicant conducts research and improvement, and provides a base structure of an earthen extractor, which has the characteris...
