Background Art

[0002] In mineral resource exploration and geological surveys, sampling of shore sand is a key task, which is directly related to the accurate determination of the location and scale of the ore deposit. However, existing sampling devices and methods have some limitations. On the one hand, deep sediments usually have a higher hardness, and existing sampling devices do not have a special crushing structure, making it difficult to penetrate these hard strata. Since hard rocks or dense sediments cannot be crushed, the sampling depth of the sampling device is severely limited and the target depth cannot be reached, resulting in the collected data not being able to fully reflect the distribution of underground resources. On the other hand, the outlet of the sampler is designed to be too narrow, and there may be a rough or non-smooth surface inside the sampler, resulting in friction between the sample and the inner wall, making it difficult to remove the sample smoothly, or samples at different depths are mixed during the removal process, thus affecting the sampling accuracy.

[0003] Publication No. CN219455527U discloses a grab bucket type sampler, comprising a frame (1), wherein a top plate (2) is disposed at the upper end of the frame (1), a lifting cylinder (3) is disposed at the lower part of the top plate (2), an angle adjustment mechanism (4) is connected to the protruding end of the lifting cylinder (3), and a sampling grab bucket (5) is disposed at the bottom of the angle adjustment mechanism (4); the angle adjustment mechanism (4) comprises a main body seat (6) connected to the protruding end of the lifting cylinder (3); Publication No. CN213301760U discloses a novel sludge sampler, wherein a handle is connected to the lifting cylinder (3) by a pull rope installed in an operating rod. Spring, the bottom of the handle is connected to the operating rod by a first fixing screw, the bottom of the operating rod is connected and fixed to the three-way branch pipe by a second fixing screw, the bottom of the pull rope is provided with a lifting ring, and the top of the grab is provided with a through hole, the bottom of the pull rope and the top of the grab are connected at the same point by connecting screws passing through the lifting ring and the through hole respectively, and the spring is placed in the three-way branch pipe. The above-mentioned sampler can only collect surface coastal sand, but cannot collect deep coastal sand and cannot reach the target depth, so that the collected data cannot fully reflect the distribution of underground resources, and cannot collect coastal sand with higher hardness, and has low practicality.
