Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a rock and soil sampling device for water conservancy project detection. 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. Water is a valuable resource that is indispensable to human production and life, but its natural state does not fully meet human needs.

[0003] The known authorized patent with application number: CN202222650733.2 discloses a rock and soil sampling device for water conservancy project inspection. Its background technology proposes the problem that "the current traditional method of sampling soil using a test cup or a shovel makes it difficult to extract soil at different depths, and there are rocks and grass on the periphery of the soil, which affects the extraction of soil and causes inconvenience in sampling." Therefore, the technical solution to this problem is: "including a device body, a sampling mechanism and a supporting and protective mechanism. The device body includes a machine platform, a telescopic column and a support plate; the telescopic column is fixedly connected to the upper end of the machine platform; the support plate is movably connected to the upper end of the telescopic column; a sampling mechanism is installed inside the device body; the sampling mechanism includes a cylinder, a material barrel, a material transfer shaft, a stone opening plate, a material discharge port, a material box and bolts; the cylinder is fixedly connected to the upper end of the support plate; the material barrel is inserted into the inside of the machine platform; the material transfer shaft is movably connected to the inside of the material barrel" and so on.

[0004] However, in the implementation of relevant technologies, it was found that the above technical solution has the following problems: when it is used, it is not convenient to classify and collect the removed soil, gravel and other impurities. It rotates the material transfer shaft and the stone plate, sweeps the stones and weeds aside through the stone plate, and spirally transmits the sample upward through the material transfer shaft to complete the sampling. However, impurities such as gravel in the soil layer will be discharged and collected together with the sample, which may easily cause the gravel and other impurities to mix with the sample soil. Subsequently, personnel will need to conduct secondary screening, which is troublesome and time-consuming, resulting in reduced sample purity and reduced efficiency and convenience of detection.
