Description

Technical Field

[0001] The utility model mainly relates to the field of soil sampling equipment, in particular to a soil sampler for water conservancy project supervision. 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. The construction of sluice gates, canals, etc. are all water conservancy projects, especially sluice gates, which are convenient for water storage and irrigation. When building some water conservancy facilities such as sluice gates, it is necessary to survey and supervise the geology to avoid the collapse of the constructed sluice gates. This requires soil samplers to sample and test the soil. The existing technology requires manpower to insert the cylinder into the ground, which results in greater effort when sampling deeper soil, resulting in increased workload for staff; at the same time, the existing samplers need to perform multiple sampling when sampling soil at different depths, and it is difficult to quickly obtain samples at different depths, resulting in low sampling efficiency.

The utility model has a simple structure and is easy to use. It is powered by a motor and can simultaneously drive two collection tubes to rotate with the cooperation of a first sprocket, a second sprocket and a chain. The extension and contraction of the telescopic rod can make the collection tubes contact the ground and take samples, thereby improving the sampling efficiency and reducing the physical labor of the operator.
