Multi-point centralized soil fetcher

Abstract

The invention relates to a multipoint centralized soil sampler. The soil sampler comprises a housing of a shell structure, wherein an opening is formed in the lower end of the housing, and an open pore is formed in the upper end of the housing; a base is arranged at the lower end of the inner cavity of the housing, a central rotating wheel is arranged at the upper end of the inner cavity of the housing, and a rotating rod is arranged at the upper side of the wheel surface of the central rotating wheel; a plurality of sampling rods are arranged on the base, a sampling sleeve is arranged at the lower end of each sampling rod, and is sleeved by a guide sleeve, and the guide sleeve is fixedly connected to the base; a side rotating wheel engaged with the central rotating wheel is arranged at the upper part of each sampling rod, and is spirally connected with each sampling rod; the centre of the central rotating wheel is spirally connected with each sampling rod, the upper end of each sampling rod stretches out from the open ore, and the sampling sleeve at the lower end of each sampling rod penetrates through the center of the base. A simultaneous sampling manner of the plurality of sampling rods is adopted in the invention, compared with the traditional single-point sampling manner, the sampling efficiency is greatly improved; simultaneous sampling is carried out on multiple points on the surrounding of one sampling point to improve the sampling operation reliability and improve the detection accuracy and reasonability of a soil sample.

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. Contents of the invention [0003] In view of the above-mentioned shortcomings in the existing prior art, the applicant conducts research and improvement, and provides a soil fetching device with reasonable structure, convenient use and high soil retrieval efficiency. [0004] The technical scheme adopted in the present invention is as follows: [0005] The soil extractor comprises a casing with a shell structure, the lower end of the casing has an opening, and the upper end has an opening; There are multiple sampling rods Ⅰ and Ⅱ installed on the base...

AI Technical Summary

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.
