Problems solved by technology

[0003] At present, when surveying the soil layer, it is necessary to use soil-taking tools to sample the ground and the soil deep in the ground. The existing soil-taking tools have a relatively simple structure. Most of the sampling rods are drilled deep into the ground, and the soil enters the sampling rod. The inside can be taken out with the sampling rod. However, the soil that enters the sampling rod is difficult to take out from the inside of the sampling rod due to compaction, which will affect the subsequent further analysis of the soil and also affect the subsequent use again.

Embodiment 1

[0027] see Figure 1-3 , this embodiment provides an environmental geology sampling device, including a cylindrical cylinder 2, a sampling assembly 5 and a first driving assembly for driving the sampling assembly 5 to move up and down inside the cylindrical cylinder 2, specifically, the The sampling assembly 5 includes a first arc-shaped plate 12 and a second arc-shaped plate 16 opposite to each other. The first arc-shaped plate 12 and the second arc-shaped plate 16 can form a cylindrical structure. The first arc-shaped plate 12 The side opposite to the second arc-shaped plate 16 is provided with a sampling gap 13, and the side of the first arc-shaped plate 12 and the second arc-shaped plate 16 is fixedly provided with an extension rod 14, and the end of the extension rod 14 is telescopic and A support seat 17 is elastically fitted; the first drive assembly includes a screw rod 3 that vertically penetrates the support seat 17 and is threadedly engaged with the support seat 17,...

Embodiment 2

[0037] see figure 1 , an environmental geological sampling device. Compared with Embodiment 1, this embodiment is fixed with a base 1 on the outside of the bottom of the cylinder 2. Through the setting of the base 1, the contact area with the ground can be increased, and the device can be further improved. Stability during sampling.

[0038]In the embodiment of the present invention, the first drive assembly drives the sampling assembly 5 to move up and down, so that the sampling assembly 5 is inserted into the soil layer and then the soil is taken out. After sampling and analysis, the second drive assembly drives the first arc-shaped plate 12 and The second arc-shaped plates 16 are far away from each other, so that the soil inside the first arc-shaped plate 12 and the second arc-shaped plate 16 is discharged by itself. Compared with the prior art, it has the advantages of simple structure, convenient use and good sampling effect.

Abstract

The invention provides an environmental geology sampling device, and belongs to the technical field of environmental monitoring. The environmental geology sampling device comprises a column casing, the column casing is internally provided with a sampling assembly and a first driving assembly used for driving the sampling assembly to move up and down; the sampling assembly comprises a first arc-shaped plate and a second arc-shaped plate which are oppositely arranged, a cylindrical structure can be defined by the first arc-shaped plate and the second arc-shaped plate, and sampling notches are formed in the opposite sides of the first arc-shaped plate and the second arc-shaped plate. In the embodiment of the invention, the first driving assembly drives the sampling assembly to move up and down, so that the sampling assembly is inserted into a soil layer to take out soil, and after sampling analysis, the second driving assembly drives the first arc-shaped plate and the second arc-shaped plate to be away from each other, so that the soil in the first arc-shaped plate and the second arc-shaped plate is automatically discharged; compared with the prior art, the device has the advantages of simple structure, convenience in use and good sampling effect.

Description

technical field [0001] The invention belongs to the technical field of environmental monitoring, in particular to an environmental geological sampling device. Background technique [0002] Geological exploration can be understood as geological work in a broad sense. It is based on the needs of economic construction, national defense construction, and scientific and technological development, using geological exploration methods such as surveying and mapping, geophysical prospecting, geochemical prospecting, drilling, pit exploration, sampling testing, and geological remote sensing. , Investigation and research work on geological conditions such as rocks, stratum structures, minerals, groundwater, and landforms in a certain area. [0003] At present, when surveying the soil layer, it is necessary to use soil-taking tools to sample the ground and the soil deep in the ground. The existing soil-taking tools have a relatively simple structure. Most of the sampling rods are drille...
