Problems solved by technology
[0005] Aiming at the deficiencies of the prior art, the present invention provides a multi-functional wetland soil sampling device, which solves the problem that due to the inhomogeneity of the spatial distribution of the wetland soil itself, multi-point sampling is required during collection, and then mixed into a mixed sample to collect The process is cumbersome, time-consuming and labor-intensive, which affects the efficiency of subsequent wetland soil sampling, and commonly used wetland soil sampling devices have single functions and poor functionality, which affects the practicability of wetland soil sampling devices

The invention relates to the technical field of soil sampling, and discloses a multi-functional wetland soil sampling device which comprises a first air bag, a second air bag, a first communicating vessel, a sample storage tank and a main body sampling pipe. The first air bag is located in a first air bag clamping seat, and the first air bag penetrates through the upper surface of the first air bag clamping seat and is clamped and fixed to the first air bag clamping seat. The second air bag is located in a second air bag clamping seat, and the second air bag penetrates through the lower surface of the second air bag clamping seat. Through the combined action of the first air bag and the second air bag, suction force is generated through extrusion, a sampling head is inserted into wetland soil to suck a mud-water mixture, the mud-water mixture is guided into the first air bag and the second air bag through the main body sampling pipe and finally flows into the sample storage tank to besucked and mixed again at the next sampling point, subsequent multi-point sampling is facilitated, the sample pouring-out time is saved, the sampling efficiency is improved, and the subsequent detection precision is guaranteed.
Description
technical field [0001] The invention relates to the technical field of soil sampling, in particular to a multifunctional wetland soil sampling device. Background technique [0002] Soil sampling refers to the method of collecting soil samples, including the arrangement of samples and sampling techniques. Section soil samples should be taken after the section observation and record are completed. Before sampling, the profile should be trimmed and cleaned to remove the top layer of floating soil, and then samples should be taken from the typical central part layer by layer from top to bottom. When analyzing metals in soil, sampling with metal utensils should be avoided. [0003] In order to study the composition of wetland soil, it is often necessary to sample the wetland soil. Due to the heterogeneity of the spatial distribution of the wetland soil itself, it is necessary to take multiple samples and then mix them into a mixed sample. The collection process is cumbersome, t...
