Soil sampling device used for soil testing

Abstract

The invention discloses a soil sampling device used for soil testing, and relates to the technical field of soil sampling. The soil sampling device comprises a support frame and a sampling device, wherein the support frame is fixedly provided with a sampler, the sampler comprises an outer barrel, a circular ring is arranged on the outer side of the top of the outer barrel, and one surface of the circular ring is provided with a limiting column; the internal threads of the outer barrel are in normal running fit with an inner barrel; a limiting ring is arranged on the inner side wall of the inner barrel; a rotating shaft is arranged on the sampler in a matched manner, and a rotary handle is arranged at the top of the rotating shaft; and the rotating shaft is connected with the thread of theinner wall of the inner barrel in a rotating manner. The sampling device consisting of the support and the sampler is simple in structure, and simultaneously, the sampler is driven to be sunk into soil for sampling by rotating the rotary handle, so that the problem that a conventional sampling device is inconvenient in operation is solved.

Description

Technical field [0001] The invention belongs to the technical field of soil sampling, and particularly relates to a soil sampling device used for soil testing. Background technique [0002] The collection of soil samples is the foundation of soil scientific research and geological survey fields, and provides a material basis for the determination of the physical and chemical properties of soil samples. There are many methods for soil sampling. In the prior art, drill pipe sampling is generally used. When the drill pipe is drilled underground Later, the soil formed a soil column in the drill pipe, and the entire soil column was taken out for analysis. Existing sampling devices often form soil pillars after sampling, and the shape of the soil pillars will be destroyed after being taken out. The different sampling levels and depths in the soil pillars are usually mixed together, that is, the different sampling levels and depths cannot be measured. The samples are distinguished. [0...
