Description

Technical Field

[0001] The utility model relates to the technical field of soil sampling, in particular to soil sampling equipment. Background Art

[0002] According to the announcement number "CN 216247321 U", a soil sampling device for water conservancy projects is disclosed. The soil sampling device for water conservancy projects uses a double-axis motor and a screw rod as well as a top plate and a limit column. After the soil sampling device for water conservancy projects is pushed to an appropriate position as a whole, the staff can start the double-axis motor. The double-axis motor drives the screw rod to rotate through the transmission of the bevel gear, and then pushes the top plate to move downward and lifts the device as a whole, so that the pulley is away from the ground. At the same time, the limit column at the bottom of the top plate can be inserted into the soil, thereby ensuring the stability of the device as a whole when working.

[0003] However, the current soil sampling devices for water conservancy projects often need to sample soil at different locations and depths, so multiple sampling is required. The sampled soil needs to be stored before the next sampling, and the state at the time of sampling cannot be completely maintained, resulting in low sampling efficiency and poor sampling quality. Therefore, there is an urgent need for a soil sampling device with a sampling head that can be quickly disassembled and assembled, which can be used for sampling at different depths and can be stored separately so that the soil can always maintain the consistency of the soil at the time of sampling.
