[0002] Accurate and efficient soil sampling is crucial for soil pollution source detection. Traditional soil sampling methods often rely on manual excavation or the use of simple sampling tools. These methods are not only labor-intensive and inefficient, but also struggle to ensure sampling depth and accuracy. With the advancement of technology, some mechanized soil sampling devices have been gradually introduced. However, these devices are often complex in structure, cumbersome to operate, and require the use of power tools, which imposes numerous limitations on their use in the field.

[0003] In order to solve the above problems, the utility model proposes a soil pollution source detection sampling device. Utility Model Content

[0028] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Specific embodiment one:

[0030] See also Figure 1-6 As shown, the utility model is a soil pollution source detection sampling device, and its structure includes a sampling bracket 1, a sampling tube 2, a sampling tube drive terminal 3, a drive commutator 4, and a shaft-belted bevel gear 5. The sampling tube 2 is used to take soil deep into the soil layer. The shaft-belted bevel gear 5 rotates to drive the drive commutator 4 to rotate and then drives the sampling tube drive terminal 3 to achieve up and down movement. The sampling tube drive terminal 3 is connected to the sampling tube 2 using a pin 6. The sampling tube 2 is pressed into the soil layer under the drive of the sampling tube drive terminal 3. After the sampling tube 2 is fully inserted into the soil layer, the shaft-belted bevel gear 5 is rotated in the opposite direction to drive the sampling tube drive terminal 3 and the sampling tube 2 through the drive commutator 4 to take out the sampling tube 2 containing the soil sample upward.

[0031] The sampling cylinder drive terminal 3 specifically includes a cylinder 31. A circular plate 32 is fixed to the upper end of the cylinder 31. A screw 33, coaxially arranged with the cylinder 31, is fixed to the upper end surface of the circular plate 32. The cylinder 31 is provided with a plurality of first circular through holes 34 arranged along its radial direction. The upper end of the sampling cylinder 2 is provided with a plurality of second circular through holes 21 arranged along its radial direction. The upper end of the sampling cylinder 2 is inserted into the cylinder 31 and connected to the pin 6 extending through the first circular through hole 34 and the second circular through hole 21.

[0032] The drive commutator 4 is mounted on the upper end of the sampling bracket 1 via a seat bearing 7. The shaft bevel gear 5 is rotatably mounted on the sampling bracket 1 via a bearing 8. The shaft bevel gear 5 and the drive commutator 4 are meshed and driven. The screw 33 passes through the drive commutator 4 and is threadedly connected thereto.

[0033] Among them, the sampling bracket 1 includes a rectangular base plate 11. A circular tube 12 is fixed through the middle of the rectangular base plate 11. Two columns 13 are fixed on the upper surface of the rectangular base plate 11 symmetrically about the axis of the circular tube 12. A horizontal surface 14 is fixed at the upper ends of the two columns 13. The horizontal surface 14 is provided with a third circular through hole 15 coaxially arranged with the circular tube 12. The seat bearing 7 is installed on the horizontal surface 14, and the seat bearing 7 is coaxially arranged with the third circular through hole 15. A vertically arranged perforated vertical plate 16 is fixed on one side of the horizontal surface 14. The shaft bevel gear 5 is installed on the perforated vertical plate 16 through the bearing 8. The drive commutator 4 includes an internal threaded sleeve 41 threadedly connected to the screw 33. The lower half of the internal threaded sleeve 41 is installed on the seat bearing 7. The outer wall of the upper half of the internal threaded sleeve 41 is fixed with a bevel gear disc 42 that meshes with the shaft bevel gear 5 for transmission.

[0034] In order to improve the ability of the sampling tube 2 to split the soil layer during the downward movement, a circle of cutting teeth 22 is provided at the lower end of the sampling tube 2.

[0035] Wherein, the free end of the circular shaft of the tapered gear 5 is provided with a coaxially arranged joint 51 with an oblong cross section. A crank 9 is plugged and installed on the joint 51. In addition to being driven by the crank 9, the tapered gear 5 can also be driven by an electric wrench.

[0036] The crank 9 specifically includes a crank handle 91. A sleeve 92 connected to the connector 51 is fixed to one side of one end of the crank handle 91. A handle rod 93 is fixed to the other side of the other end of the crank handle 91. The crank handle 9 indirectly drives the upward and downward movement of the sampling tube 2 during soil sampling, which is unrestricted for field operations and is more suitable for field use than sampling devices driven by power tools. The present utility model has a reasonable and simple overall structure, is easy to use and operate, and is lightweight and portable, making it suitable for field use for soil sampling.

[0037] When using Figure 1 The sample tube 2 is assembled in the state, the rectangular base plate 11 is placed on the sampling site, and the sampling personnel stand on the rectangular base plate 11 for counterweight. When sampling, the sampling tube driving terminal 3 is driven by the hand crank 9 to carry the sampling tube 2 downward into the soil layer to cut the soil layer for sampling. After the sampling tube 2 completely enters the soil layer, the sampling tube 2 is pulled out of the soil layer by the reverse hand crank 9. After the sampling tube 2 is pulled out, the pin 6 is pulled out to take out the sampling tube 2 carrying the soil sample for storage. The rigid structure of the sampling tube 2 is conducive to the preservation of its internal soil layer structure. When used for detection, a rod is inserted into the bottom of the sampling tube 2 to push out the pattern inside it. The pushed-out soil sample is presented in a columnar form, which is convenient for sampling, detection and analysis of soil layers at different depths. The use of the sampling tube 2 to directly store soil samples is conducive to layered detection and analysis of the degree of contamination of the soil layer.
