Description

Technical Field

[0001] The utility model relates to the field of geological exploration, and more specifically, to a sampling device for geological exploration. Background Art

[0002] When constructing a building or conducting a geological survey of a certain place, it is often necessary to conduct experimental tests on the soil geological conditions of the place. During the experimental test, it is often necessary to sample the soil of the place, so it is necessary to use a sampling structure to obtain the soil. The existing sampling device generally samples the soil through a sampling tube, but the volume of the sampling tube is fixed, and the volume of soil that can be collected at one time is fixed. It is impossible to obtain the required volume of soil according to the sampling needs. Therefore, after the operator completes the sampling, it is still necessary to select the required volume from the sampled soil, which reduces the operator's soil collection efficiency and increases the time required for sampling. At the same time, the existing sampling device is generally a fixed frame structure, and the sampling tube is fixedly installed on the sampling structure, which is inconvenient to disassemble. Therefore, when the operator needs to sample a shallower position of the soil but it is inconvenient to carry the entire sampling device for sampling, the sampling device cannot be used for sampling, which affects the use of the sampling device and the portability of the entire sampling device is poor.

[0015] (3) Beneficial effects

[0016] Compared with the prior art, the present invention provides a sampling device for geological exploration, which has the following beneficial effects:

[0017] 1. The utility model obtains soil by setting a sampling tube. When fixing the volume of the sampling tube, the pull rod cooperates with the first ring set on the mounting cap, and the different positioning holes on the pull rod cooperate with the positioning holes on the first ring. The bolt is inserted into the positioning hole to fix the position of the pull rod, so that the position of the push plate is changed by the pull rod, thereby realizing the change of the volume of the sampling tube. This makes it convenient for the operator to change the volume of the sampling tube according to the sampling needs, saves the time of re-arranging the soil, and improves the sampling efficiency.

[0018] 2. The utility model connects the intermediate rod and the movable block through a connecting pipe. When the sampling tube needs to be disassembled, the bolts of the connecting pipe and the connecting hole opened on the intermediate rod are removed to separate the connecting pipe from the intermediate rod. This makes it easy for the operator to manually sample the shallow soil only through the cooperation of the intermediate rod and the sampling tube, thereby improving the applicability of the entire sampling device.

[0019] 3. The utility model sets the diameter of the soil wheel and the push plate to be the same as the inner diameter of the sampling tube. Therefore, when the entire sampling device is not in use, the second ring provided on the mounting cap and the bolts in the fixing hole provided on the intermediate rod are removed, and the intermediate rod is pulled to move, thereby receiving the soil wheel into the sampling tube. This facilitates the protection of the soil wheel and reduces the soil wheel from colliding with the external environment when not in use, which may cause damage to the soil wheel and affect the service life of the entire sampling device.
