Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a soil quality detection and sampling device for water conservancy projects. Background Art

[0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. They are also called water projects. Only by building water conservancy projects can we control water flow, prevent floods and disasters, and regulate and distribute water to meet the people's needs for water resources in life and production. Soil quality testing plays a vital role in the construction of water conservancy projects, and sampling devices are required for soil quality testing.

[0003] During the soil sampling process, manual labor is required to press the threaded sampler downward and make contact with the ground for sampling. If the ground is relatively hard, the operation is more laborious, which increases the labor burden of the personnel. Therefore, there is also a problem of low degree of automation and reduced work efficiency.

[0004] The existing patent (publication number: CN218381751U) is a construction soil testing and sampling device. Through a simple structure, it realizes the automatic lifting and lowering operation of the threaded sampler, reducing the labor burden of personnel and improving work efficiency. It can perform soil sampling on relatively hard ground and is highly practical.

[0005] In response to the above problems, existing patents have provided solutions, but the above-mentioned sampling device may adopt a more integrated structural design, with the various components tightly combined and no clear disassembly interface or method, which makes it difficult to thoroughly clean the various components of the device after use. Soil may remain inside the device, thereby affecting the accuracy of the next use.

[0006] Therefore, a soil quality detection and sampling device for water conservancy projects is proposed. Utility Model Content
