[0002] The main purpose of geological exploration is to find and identify underground mineral deposits, providing necessary information and data support for subsequent resource development and utilization. This mainly includes determining the location of mineral deposits, assessing the quality of mineral deposits, understanding the mining conditions of mineral deposits, and providing a basis for resource development. Geological exploration is an important prerequisite and foundation for resource development and utilization. Through geological exploration, we can understand the situation of underground resources and provide necessary support and guarantees for economic development and social progress.

[0003] In existing technologies, the sampling methods used in geological exploration mainly include direct sampling methods, which include borehole sampling and excavation sampling. Borehole sampling is carried out by drilling with drilling equipment, while excavation sampling is carried out by excavating a trench or pit at the location where sampling is required, and then obtaining samples from the excavated area.

[0004] Long-term observation revealed that current geological exploration sampling devices can often only sample one sampling method at a time. When drilling and excavation sampling methods are used simultaneously, staff need to carry multiple tools to sample the soil. This not only increases the burden on staff, but also makes it inconvenient for staff to carry the numerous sampling devices. Therefore, it is necessary to design a reasonable portable geological exploration sampling device to solve the above problems. Utility Model Content

A sampling shovel 16 is fixedly connected to the bottom of the first support cylinder 13. A sampling spike 12 is opened at the bottom of the sampling rod assembly 11.

[0027] When drilling is required, the first sampling rod assembly 11 is rotated out of the first support cylinder 13, separating the sampling cylinder from the first support cylinder 13 and the sampling shovel 16. With the assistance of the sampling spike 12 at its bottom, the sampling rod assembly 11 is drilled into the ground for sampling. When excavation is required, the sampling rod assembly 11 is reconnected to the first support cylinder 13 through the first threaded groove 14 and the first spiral 15. At this time, the staff can excavate and sample through the sampling shovel 16 connected to the first support cylinder 13, which makes it easier for the staff to carry and reduces their burden.

[0028] In this utility model, the sampling spike 12 is located at the bottom of the sampling rod assembly 11 and inside the sampling rod assembly 11. When the sampling rod assembly 11 and the first support cylinder 13 are connected, the connection will not be hindered by the sampling spike 12.

By providing a leverage seat 6, the worker can use the sampling shovel 16 to dig and sample the soil more easily, thereby facilitating the worker's digging and sampling and further improving the worker's work efficiency.

[0037] The method of using the portable sampling device for geological exploration of this utility model is as follows:

[0038] When workers need to drill holes to sample the soil, they can insert the sampling rod assembly 11 into the soil by pressing the hand handle 1 downwards with the sampling rod assembly 11 perpendicular to the ground, thereby drilling holes to sample the soil.

[0039] When workers need to excavate and sample the soil, they rotate the first support cylinder 13 to the bottom of the sampling rod assembly 11, and then fix the sampling shovel 16 to the bottom of the sampling rod assembly 11 through the first support cylinder 13, the first threaded groove 14 and the first spiral 15, so that workers can excavate and sample the soil.

[0040] After the staff has finished drilling and sampling the soil, they press the pressing plate 22 to move the sliding rod 2 downward along the hand handle 1, thereby pushing the sample taken from the borehole out of the sampling rod assembly 11.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
