[0002] Soil sampling is fundamental to soil science research and geological exploration, providing the material basis for determining the physical and chemical properties of soil samples. There are many methods for soil sampling. Existing techniques generally use drill pipe sampling. Once the drill pipe is drilled into the ground, the soil forms a column within the pipe. The entire column is then removed for analysis, but this sampling drill pipe is unable to distinguish between samples taken at different levels and depths. Existing techniques require that after removing soil using a ring cutter, Luoyang shovel, or other tool, the user must transfer the soil to a storage container, which is inefficient. Furthermore, when the soil is dry and hard, it can become trapped within the ring cutter or Luoyang shovel, making it difficult to remove, increasing operational complexity. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0020] like Figure 1As shown, an embodiment of the present invention provides a soil sampling device comprising a spiral rod 3, a connecting rod 5, a fixed frame 1, a placement frame 12, a fixed sleeve 2, a drive assembly, a control assembly, and a discharge assembly. The fixed sleeve 2 is cylindrical and has an opening at its bottom. The fixed sleeve 2 is vertically mounted and fixedly connected to the fixed frame 1. The outer diameter of the spiral rod 3 fits and rotates with the inner bore of the fixed sleeve 2. The connecting rod 5 is coaxial with the spiral rod 3 and is fixedly connected at its top. The upper portion of the connecting rod 5 extends outwardly beyond the fixed sleeve 2. A through hole is provided at the top of the fixed sleeve 2 for the connecting rod 5 to pass through, with a clearance fit between the connecting rod 5 and the through hole. The placement frame 12 is rotationally connected to the fixed sleeve 2. Several storage cylinders 15 are disposed on the placement frame 12, surrounding the fixed sleeve 2. The tops of the storage cylinders 15 are opened. The discharge assembly is located above the placement frame 12 and communicates with the interior of the fixed sleeve 2. The discharge assembly is used to direct soil into the storage cylinders 15 located to the sides or below. When the spiral rod 3 moves downward and drives the soil upward, it is shallow soil and may be mixed with other debris. Therefore, this part is directed to the side and discharged, and the subsequent soil is then introduced into the storage cylinder 15. The drive assembly is fixedly connected to the fixed frame 1 and is used to drive the connecting rod 5 to rotate. The control assembly is rotatably connected to the top of the connecting rod 5 and is used to control the vertical movement of the connecting rod 5.

[0021] Preferably, the control assembly includes a thrust ball bearing 6, a first connecting rod 7, a second connecting rod 8, and a grip 10. The inner ring of the thrust ball bearing 6 is fixedly connected to the top of the connecting rod 5. The first connecting rod 7 is horizontally arranged, with one end of the first connecting rod 7 fixedly connected to the outer ring of the thrust ball bearing 6. The second connecting rod 8 is vertically arranged, with the top of the second connecting rod 8 fixedly connected to the free end of the first connecting rod 7. The lower end of the second connecting rod 8 is vertically slidably connected to the fixed frame 1, and the grip 10 is fixedly connected to the lower end of the second connecting rod 8. In this embodiment, a vertical T-shaped sliding groove is provided on the fixed frame 1, and a sliding connection block 9 that is compatible with the T-shaped sliding groove is fixedly connected to the bottom of the second connecting rod 8. When the soil sampling device is moved to the sampling site, the staff then slides the second connecting rod 8 downward using the grip 10, which then causes the first connecting rod 7 to drive the spiral rod 3 below the connecting rod 5 downward.

[0022] like Figure 2 As shown, preferably, a plurality of placement cavities with openings upward are arranged around the placement rack 12, and the storage cartridge 15 is placed in the placement cavity. After the sampling is completed, the storage cartridge 15 can be removed from the placement rack 12 and transferred to a place where the experimental analysis is performed.

[0023] like Figure 3As shown, the discharge assembly preferably includes a guide tube 11, a first baffle 16, and a second baffle 17. The guide tube 11 is a rectangular shell with openings at both ends. The upward end of the guide tube 11 communicates with the middle of the fixed sleeve 2. A lower outlet 19 corresponding to the storage cylinder 15 is provided in the middle of the bottom surface of the guide tube 11. The first baffle 16 is slidably connected to the bottom of the guide tube 11 to open and close the lower outlet 19. The second baffle 17 is vertically arranged and slidably connected to the top of the guide tube 11 to block or open the internal passage of the guide tube 11. The second baffle 17 is located on the side of the lower outlet 19 away from the fixed sleeve 2. When the screw rod 3 conveys soil upward, the soil is discharged from the guide tube to the outside of the fixed sleeve 2 and away from the sampling area. When soil needs to be directed to the storage cylinder 15, the first baffle 16 is first slid to open the lower outlet 19, and then the second baffle 17 is slid downward to seal the bottom of the guide tube 11, allowing the soil to be discharged from the lower outlet 19. In this embodiment, the guide tube 11 is provided with bolts 18 for fixing the first baffle 16 and the second baffle 17.

[0024] Preferably, a guide tube 23 is fixedly provided at the lower outlet 19 , and a through hole of the first baffle 16 is provided on the side of the guide tube 23 . When the soil is discharged from the lower outlet 19 , the guide tube 23 causes the soil to fall downward into the storage cylinder 15 in a relatively concentrated manner.

[0025] Preferably, a detachable sealing cover is provided on the top of the storage cylinder 15. The sealing cover prevents soil from other sampling points from entering.

[0026] Preferably, a plurality of rollers 13 for movement are provided at the bottom of the fixing frame 1, so that the staff can push the fixing frame 1 to move to different sampling points, making the operation more convenient and labor-saving.

[0027] Preferably, the drive assembly includes a first gear 21, a second gear 22 and a motor 20, the first gear 21 being arranged on the connecting rod 5, the motor 20 being fixedly connected to the fixing frame 1, the second gear 22 being fixedly arranged on the output shaft of the motor 20, the first gear 21 and the second gear 22 being meshed, and the width of the first gear 21 being equal to the length of the connecting rod 5. In this embodiment, a battery is placed on the fixing frame 1 to provide power supply to the motor 20, which is convenient for outdoor operation. A reducer is provided on the output shaft of the motor 20. When the motor 20 drives the second gear 22 to rotate, the first gear 21 and the second gear 22 are meshed. The connecting rod 5 moves in the vertical direction without affecting the meshing of the first gear 21 and the second gear 22. The length of the connecting rod 5 is equal to the vertical movement stroke of the second connecting rod 8.

[0028] Preferably, a trumpet-shaped material guide nozzle 14 is slidably provided at the bottom of the fixed sleeve 2, and the material guide nozzle 14 opens downward. A gap is provided between the fixed sleeve 2 and the ground, and when sampling, the open end of the material guide nozzle 14 is in contact with the ground.
