Problems solved by technology
It is mainly to extract the original test soil as a sample to understand the nature of the base layer through the rock and soil sampling device, but the existing sampling device for rock and soil testing has a large volume, takes up a lot of space during the carrying process, and is not easy to carry. During the sampling process of the device, the drill bit and the sampling drill pipe are prone to inclination, so that there is a large error between the actual sampling depth of the rock and soil and the sampling depth of the rock and soil that needs to be detected theoretically. It is difficult to achieve accurate sampling of the rock and soil in the vertical direction, which affects the Accuracy of Soil Sampling Detection
At the same time, due to the unreasonable design and structure of the existing sampling device, there are technical problems such as labor intensity and low production efficiency during use.

The invention discloses a geotechnical sampling device suitable for a geotechnical detection. The device includes a mounting plate, a drill bit, a driving motor, a storage battery, a guiding cylinder,a transmission rod, a fixed transmission guiding block, telescopic adjusting supporting legs and a turbine. The telescopic adjusting supporting legs are connected to the bottom of the mounting plate.The guiding cylinder is connected to the upper part of the mounting plate. The storage battery is connected to the top of the mounting plate at the outer side of the guiding cylinder. The fixed transmission guiding block is slidably connected to the inner wall of the guiding cylinder. The top of the transmission rod is rotatably connected to the fixed transmission guiding block. The transmissionrod is connected to the mounting plate by threads. The bottom of the transmission rod is connected to the drill bit. An output shaft of the driving motor is fixedly connected to the turbine. The turbine is engaged with the outer side of the transmission rod. The storage battery is electrically connected to the driving motor. The geotechnical sampling device suitable for the geotechnical detectioncan effectively reduce the labor intensity, improve the production efficiency and is convenient in carrying and good in stability.
Description
Technical field [0001] The invention relates to the field of rock and soil testing equipment, and in particular to a rock and soil sampling device suitable for rock and soil testing. Background technique [0002] The structure and properties of the rock and soil have an important influence on the bearing performance. The sampling and analysis of the rock and soil is an indispensable and important work link before construction. It is mainly to extract the original test soil from the rock and soil sampling device as a sample to understand the properties of the base layer. However, the existing sampling device for rock and soil testing is large in size and occupies a large space during the carrying process, which is not convenient for carrying and sampling. During the sampling process of the device, the drill bit and the sampling drill pipe are prone to tilt, which makes the actual rock and soil sampling depth and the theoretically required rock and soil sampling depth have a large ...
