Abstract

The invention relates to a multipoint 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, the sampling sleeve 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 the side rotating wheel 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; the lower end of the sampling sleeve is provided with a shrinkable sleeve, and the shrinkable sleeve is provided with a conical shrinking structure with the lower end smaller than the upper end. The multipoint soil sampler provided by the invention is simple in structure, reasonable in design, convenient to operate and high in reliability.

Description

Technical field [0001] The invention relates to the field of geological prospecting equipment, in particular to a soil extractor. Background technique [0002] In the field of geological prospecting, soil extractors are often used when collecting soil samples. When sampling, the existing soil extractor can only sample one point at a time. When sampling, the sampling rod is rotated into the underground to extract the sample. The disadvantage is that it cannot sample the surrounding area of ​​the sampling point at the same time and requires multiple sampling, which is inefficient; The reliability of the sampling rod is not high, the soil sample is easy to fall off from the sampling sleeve, and multiple sampling is required. Summary of the invention [0003] In view of the above-mentioned shortcomings in the prior art, the applicant has conducted research and improvements to provide a soil extractor with reasonable structure, convenient use and high soil extraction efficiency. [000...
