Description

TECHNICAL FIELD

[0001] The utility model relates to geological survey equipment technical field, especially relate to a kind of geotechnical sampling device for geological survey. BACKGROUND

[0002] In geological survey work, geotechnical sampling is the key link to obtain underground rock-soil information. The traditional geotechnical sampling device has many drawbacks, which seriously restricts the efficiency and quality of survey work.

[0003] Early geotechnical sampling device is extremely inconvenient in moving, usually bulky and lack of effective moving components, survey personnel often need to spend a lot of manpower and time to carry the device to the designated location, which not only increases the labor intensity, but also greatly affects the work progress. When conducting geological survey, different survey points are scattered and the terrain is complex, so the mobility of the device is required to be very flexible, and the traditional device cannot meet this demand.

[0004] When adjusting the drilling position, the traditional device also has obvious shortcomings. When a small range of adjustment is needed for the drilling position, the worker has to move the whole device due to the lack of a special adjusting component, which is time-consuming and laborious. In actual survey, accurate adjustment of the drilling position is crucial to obtain accurate rock-soil samples. This inefficient adjustment method can easily cause deviation of the drilling position, affecting the representativeness of the samples and the accuracy of the survey data.

[0005] During the process of rock-soil core sampling, the buffer protection of the drill rod is an important issue. The traditional device generally lacks effective connecting buffer components, and the drill rod is easily damaged when subjected to a large impact force. Due to the complex nature of rock-soil, the drill rod may encounter hard rock layers or other obstacles during drilling, resulting in a large impact force, which can cause problems such as jamming and drill rod damage during drilling, reducing the sampling efficiency, and even affecting the completion of the entire survey task. Without good buffer measures, the service life of the drill rod will be greatly shortened, increasing equipment costs and maintenance workload.

[0006] The unloading link is also a short board of the traditional geotechnical sampling device. The traditional device lacks auxiliary unloading components, and the unloading process is often difficult after sampling is completed, which requires workers to spend a lot of time and effort to operate, which not only reduces work efficiency, but also may damage the samples, affecting subsequent analysis and research.

[0007] In addition, the traditional device also has inconvenience in adjusting the drilling angle and storage. Due to the lack of reasonable limiting components, it is difficult to flexibly adjust the drilling angle according to actual needs, which limits its application in different geological conditions. At the same time, after use is completed, the storage of the device is also troublesome, occupying a large space, which is not conducive to the transportation and storage of the equipment.

[0008] In summary, the existing rock and soil sampling device has many deficiencies in moving, adjusting, buffering, unloading and storage, etc., and a new rock and soil sampling device is urgently needed to solve these problems and improve the efficiency and quality of geological survey work.
