Description

Technical Field

[0001] The utility model relates to the technical field of soil sampling devices, in particular to a soil sampling device for environmental assessment. Background Art

[0002] As we all know, soil refers to a loose layer of material on the surface of the earth, which can grow plants and is closely related to people's lives. Therefore, soil quality is one of the important indicators of environmental evaluation. Soil samples can be collected through the collection device, which is convenient for people to accurately and effectively evaluate the soil environment.

[0003] Existing soil sampling is often a traditional sampling method. When sampling soil, it is necessary to retain the original state of the soil as much as possible. It cannot be crushed, which will affect the evaluation results. The traditional sampling method is to dig it out manually with tools, which is time-consuming and labor-intensive, and greatly reduces the efficiency of soil sampling. In response to the above problems, this application designs a soil sampling device for environmental evaluation. Utility Model Content

The fixing bolt 10 passes through the sampling tube 6 and contacts the outer wall of the collecting half-tube 9. A second motor 11 is installed on the inner top wall of the body shell 1, and a first bevel gear 12 is fixed downwardly at the output end of the second motor 11, and the first bevel gear 12 is meshed with a second bevel gear 13. A rotating shaft 14 is fixed on the second bevel gear 13, and another second bevel gear 13 is fixed on the left and right ends of the rotating shaft 14. The two second bevel gears 13 on both sides are meshed with a third bevel gear 15, and a threaded rod 16 is fixed on the third bevel gear 15. The two threaded rods 16 are threadedly connected to the lifting block 4.

[0023] When the device is in use, the device is placed at the sampling point, the sampling tube 6 is placed downward, the first motor 5 is started to drive the sampling tube 6 to rotate, and the second motor 11 is started to drive the first bevel gear 12 to rotate, the first bevel gear 12 is meshed with the second bevel gear 13, the second bevel gear 13 drives the rotating shaft 14 to rotate, thereby driving the second bevel gears 13 on both sides to rotate, the second bevel gear 13 is meshed with the third bevel gear 15, the third bevel gear 15 drives the threaded rod 16 to rotate, and the lifting block 4 threadedly connected to the threaded rod 16 moves downward, thereby driving the sampling tube 6 to move downward. The bottom end of the sampling tube 6 contacts the soil, and the soil outside the sampling tube 6 is continuously transported upward under the action of the conveying spiral belt 7, so that the sampling tube 6 moves downward in the soil more smoothly, and the soil in the middle of the sampling tube 6 is continuously stored in the middle of the sampling tube 6.

In order to solve the above problem, in this embodiment, two pedal rods 18 were rotatably connected to the outer wall of the body shell 1 near the bottom, and the two pedal rods 18 were symmetrically distributed on the front and rear sides of the body shell 1.

[0026] In actual use, it is found that the device is relatively large and difficult to carry and move. In order to solve the above problem, in this embodiment, two connecting blocks 19 are fixed on the outer wall of the body shell 1, and a shoulder strap 20 is provided between the two connecting blocks 19.

[0027] In actual use, it is found that the situation under the soil is complicated, and there may be hard soil or even gravel, which affects the smooth downward soil sampling. In order to solve the above problem, in this embodiment, the bottom end of the sampling tube 6 is set to be blade-shaped.

[0028] It is found in actual use that the device may shake when taking soil samples. In order to smoothly carry out soil sampling, the device needs to be kept stable. In order to solve the above problem, in this embodiment, two bases 21 are fixed to the bottom end of the body shell 1. The two bases 21 are symmetrically distributed, and a plurality of thorn-shaped fixing columns 22 are fixed to the bottom end of the base 21.
