Description

Technical Field

[0001] The utility model belongs to the technical field of samplers, and in particular relates to an in-situ sampler for plateau surface soil. Background Art

[0002] Plateau topsoil refers to the topmost soil layer on the surface of the plateau area. It is the main place for plant growth and soil biological activity. When analyzing the soil composition of the plateau topsoil, it is necessary to conduct in-situ sampling of the plateau topsoil. During sampling, in order to protect the plateau soil environment and ecology and avoid cross-contamination between soils at different sampling points, the drill barrel needs to be cleaned or replaced when switching sampling points. However, in the existing technology, the sampling device does not have the function of cleaning and disinfecting the drill barrel, and the drill barrel needs to be cleaned manually, resulting in low work efficiency. Utility Model Content

At the same time, the device can automatically clean and disinfect the used drill tube 7 stored on the drill core mounting wheel 22. During cleaning and disinfection, The delivery pump 19 connected to the side of the cleaning liquid storage tank 17 is controlled to operate to pump the disinfecting cleaning liquid stored in the cleaning liquid storage tank 17 into the cleaning tank 14 through the delivery pipe 20, and the electric cylinder 25 is controlled to drive the drill core installation wheel 22 and the second motor 12 to descend, so that the drill tube 7 in the drill tube embedding groove 13 at the bottom of the drill core installation wheel 22 is immersed in the disinfecting cleaning liquid in the cleaning tank 14, and the ultrasonic transducer 15 can be controlled to operate to ultrasonically clean the drill tube 7 immersed in the disinfecting cleaning liquid. After completing the cleaning and disinfection of a group of drill tubes 7, the second motor 12 can be controlled to operate to drive the drill core installation wheel 22 to rotate, thereby taking the cleaned drill tube 7 away from the cleaning tank 14 and moving the next one. The drill barrels 7 that have not been cleaned and disinfected are brought into the cleaning tank 14 for cleaning. The drill barrels 7 that have completed cleaning and disinfection can be dried by the drying fan 21 to meet the need for quick retrieval after cleaning and disinfection. The automatic cleaning, disinfection and drying function of the drill barrel 7 can prevent microorganisms and pollutants at one sampling point from contaminating the soil at another sampling point, further reducing cross contamination. The automated cleaning and drying operation also improves work efficiency and eliminates the need for manual cleaning and disinfection. When the waste liquid needs to be discharged after use, the delivery pump 19 on the side of the waste liquid storage tank 18 is opened to pump the waste liquid in the cleaning tank 14 out to the waste liquid storage tank 18 for storage.
