Problems solved by technology

Most of the existing sampling equipment can only take samples of the same depth at a time when sampling the soil. In order to test the accuracy of the structure, it is necessary to sample the soil at different depths multiple times, which not only leads to low sampling efficiency, but also due to Sampling with the same sampler will result in the mixing of soil samples at different depths during the sampling process, which will affect the accuracy of the detection structure

Abstract

The invention discloses a multilayer depth sampling device for environmental monitoring. A plurality of sampling mechanisms for sampling soil are arranged in a sampler at equal intervals from top to bottom; each sampling mechanism comprises a fixed shaft, movable plates, push rods and a sleeve; one ends of the plurality of push rods are annularly hinged to the outer side of the sleeve at equal angles; the other ends of the plurality of push rods are respectively hinged with non-central parts of one sides of the plurality of movable plates; and the central parts of the movable plates are rotationally arranged on a fixed shaft fixed in the side wall of the sampler. According to the multilayer depth sampling device for environmental monitoring, by arranging the multiple sampling mechanisms, soil at different depths can be sampled at the same time, so that the sampling efficiency is high, soil samples at different depths cannot be mixed, and the detection result error is small; by arranging a pushing mechanism, the sampler can be driven to rotate and descend at the same time, so that the sampler can go deep into soil conveniently, and the structure of the sampler cannot be damaged.

Description

technical field [0001] The invention relates to the field of environmental detection, in particular to a multi-layer depth sampling device for environmental monitoring. Background technique [0002] When testing the environment, it is often necessary to sample the soil of the environment, and then test the sampled soil. Most of the existing sampling equipment can only take samples of the same depth at a time when sampling the soil. In order to test the accuracy of the structure, it is necessary to sample the soil at different depths multiple times, which not only leads to low sampling efficiency, but also due to Using the same sampler for sampling will result in the mixing of soil samples at different depths during the sampling process, thus affecting the accuracy of the detection structure. Contents of the invention [0003] The object of the present invention is to provide a multi-layer depth sampling device for environmental monitoring, so as to solve the problems rais...
