Problems solved by technology
[0002] At present, shallow samplers are widely used in the field of geological exploration. Shallow samplers are used for underwater sampling in shallow water areas of sandy and silty strata. Sandy strata and muddy strata are disturbed by the sampler in the saturated state, showing a liquid phenomenon, and flow into the sampler. When extracting the sampler, the water is filtered through the water leakage hole on the side of the sampler to achieve the purpose of sampling. However, shallow samplers generally require Manual operation is used, affected by various uncertain factors such as the working status of the sampling personnel and the status of the ship, the sampling accuracy is poor, and it is very easy to lose the sample with the water flow in the shallow water area during the lifting process after the sampling is completed , leading to sampling failure, and the current sampler does not have the function of accurate and continuous sampling

The invention discloses a shallow sampler, which relates to the field of geological exploration and comprises a sampler overall lifting and lowering mechanism, a sampling drive mechanism, a sampling auxiliary mechanism and a sampling unit. The design scheme of the present invention is suitable for underwater sampling in shallow water areas of sandy stratum and silt stratum. Through the integrated layout design of multiple sets of sampling units, the continuous and accurate sampling of shallow samplers is realized. The design of the storage tank makes the sampling cone After the sampling is completed, it can be attached to the bottom of the storage tank to form a closed space, which effectively avoids the occurrence of sample loss. Through the design of the sampling drive mechanism and sampling auxiliary mechanism, the sampling cone bucket rotates while diving to sample, avoiding the sampling bucket The water impact caused by direct insertion into the sample makes the sample disperse and ensure the smooth and orderly progress of the sampling work.
