Soil detection device with stratified sampling mechanism

Abstract

The invention discloses a soil detection device with a stratified sampling mechanism, and relates to the technical field of soil detection devices. The problem of the application range of the whole device is solved. The device specifically comprises a sampling column, a mounting plate is arranged on the outer wall of the top of the sampling column, a threaded rod is fixed to the outer wall of thetop of the mounting plate through a bearing, the outer wall of the top of the threaded rod is sleeved with a rotating ring, and the outer wall of the bottom end of the threaded rod is connected with four worms distributed at equal intervals through connecting rings; a rotary sampling mechanism is fixed to the outer wall of the back face, close to one side of each worm, of the sampling column through a rotating shaft, one side of each rotary sampling mechanism is meshed with the corresponding worm, four sampling holes are formed in the outer wall of the side, close to the corresponding rotary sampling mechanism, of the sampling column, and a guide rod is arranged on the outer wall of the bottom end of one worm; a guide cone is arranged on the outer wall of the bottom end of the guide rod. According to the invention, not only is the stratified sampling amount of soil improved, but also the soil can be sampled and collected under the condition of lower soil porosity.

Description

Technical field [0001] The present invention relates to the technical field of soil detecting devices, and more particularly to a soil detecting device having a layered sampling mechanism. Background technique [0002] Soil environment monitoring refers to the determination of environmental quality (or pollution) and its change trends by determination of representative values ​​affecting soil environmental quality factors. We usually say soil monitoring refers to soil environmental monitoring, which generally includes the distribution, sample preparation, analysis methods, results, statistics and quality assessments and other technical content. [0003] According to the search, the Chinese patent application No. CN201721118886.5 discloses a sampling device for soil detection, including an handle and ankle, and an anti-slip pad is provided outside the upper end of the handle, and below it passes through the telescopic rod and a fixed sleeve. The cylinder is connected to each other...

Problems solved by technology

[0004] The sampling tube is penetrated into the soil by stepping on the pedal as a whole, and when the sampling hole goes deep into the soil, the amount of soil entering the first sampling tube and the second sampling tube is limited, and when the porosity of the soil is low When the soil is hard, it is difficult to be squeezed into the sampling tube, so it is not conducive to the layered sampling of soil
