Embodiment 1

[0040]Embodiment 1, the present invention is a soil stratified sampling device for hydrogeological exploration, which includes a door-shaped support 1 composed of two vertical plates 01 and a top plate 02, and the bottoms of the two vertical plates 01 are fixedly installed with anchor pins When in use, it can be inserted into the soil for internal fixation. A lifting chute 2 runs through the left and right sides of the two vertical plates 01, and a lifting slider 3 is installed sliding up and down in the two lifting chutes 2. Each lifting slider 3 is fixedly connected with a crossbar 4 located below the top plate 02, and a lifting ring 5 is connected between two ends of the two crossbars 4 that are close to each other. The two lifting sliders 3 enable the lifting ring 5 to be placed in the door shape. Moving up and down in the support 1, the inner coaxial rotation of the lifting ring 5 is equipped with a soil drilling cylinder 6, which can rotate in the middle of the lifting ri...

Embodiment 2

[0042] Embodiment two, on the basis of embodiment one, the inner diameter of described soil-drilling cone ring 7 is less than the inner diameter of soil-drilling barrel 6, and the inner diameter of described soil-drilling cone ring 7 is the same as the inner diameter of sampling cylinder 12, in the soil-drilling barrel 6. When drilling down into the soil, the tip of the soil-drilling cone ring 7 can first separate the soil, so that the outer diameter of the columnar sample soil entering the inside of the sampling cylinder 12 is the same as the inner diameter of the soil-drilling cone ring 7 and the sampling cylinder 12, so that The outer surface of the columnar sample soil can be closely attached to the inner wall of the sampling cylinder 12 to prevent the surface of the columnar sample soil from collapsing.

Embodiment 3

[0043] Embodiment 3, on the basis of Embodiment 1, the top of the earth-drilling barrel 6 is coaxially fixed with an earth-drilling ring gear 15, and the earth-drilling ring gear 15 can rotate synchronously with the earth-drilling barrel 6, and the lifting ring 5 The top of the top is rotated and installed with a soil-drilling gear 16 meshed with the soil-drilling ring gear 15, and the soil-drilling gear 16 is coaxially fixedly connected with a soil-drilling handle 17, and rotating the soil-drilling handle 17 can be driven by rotating the soil-drilling gear 16. The earth-drilling ring gear 15 rotates, so that the earth-drilling cylinder 6 can rotate for earth-drilling.

Abstract

The invention provides a soil stratified sampling device for hydrogeological exploration. The soil stratified sampling device solves the problem that when a Luoyang shovel is used for stratified sampling of soil, it is difficult to completely and upwards take out soil samples without breaking. Comprising a door-shaped support composed of vertical plates and a top plate, lifting sliding blocks are installed in the two vertical plates in a sliding mode, the two lifting sliding blocks are fixedly connected with transverse rods, a lifting ring is connected between the ends, close to each other, of the two transverse rods, and a soil drilling cylinder is rotationally arranged in the lifting ring; an overturning plate with the axis in the left-right direction is rotationally mounted in the middle of the top plate, a sampling square rod is slidably mounted in the middle of the overturning plate, a sampling barrel is connected to the lower end of the sampling square rod, and four sampling sector plates with cambered inner and outer surfaces are hinged to the bottom of the sampling barrel. The soil drilling barrel can drill soil, so that the to-be-sampled soil can completely enter the sampling barrel to be stored, and the outer wall of the drilled soil is attached to the inner wall of the sampling barrel, so that the condition that the soil collapses and is mixed is avoided, and the soil can be completely taken out.

Description

technical field [0001] The invention relates to the technical field of hydrogeology, in particular to a soil layered sampling device for hydrogeological exploration. Background technique [0002] With the current social and economic development, soil problems are becoming more and more prominent. Driven by the Law on the Prevention and Control of Soil Pollution, soil environmental surveys are in full swing, especially for industrial production sites. Due to the heterogeneity of the soil, the collection of soil samples has become the most critical step in soil monitoring. Accurate collection of soil samples required by the specifications can provide quality assurance for various laboratory data in the later stage. [0003] At present, soil layered sampling tools on the market are too simple in structure, and sampling tools similar to Luoyang shovels are often used. When sampling, the Luoyang shovel is inserted into the soil, and then the soil can be taken out. During the pr...
