Description

Technical Field

[0001] The utility model relates to the technical field of soil taking equipment, in particular to an original soil taking device. Background Art

[0002] Using undisturbed soil for geotechnical tests can truly reflect the structural properties of the undisturbed soil on site and the physical and mechanical properties of the soil. On-site sampling of undisturbed soil requires that the original shape and structure of the undisturbed soil be maintained and no disturbance should be caused. Most existing sampling methods use a cylindrical soil sampler that is manually pressed into the soil to bring out a soil column, which is then squeezed from the top so that the soil column is pressed out of the cylindrical structure. However, due to the friction between the soil column and the inner wall of the cylinder, the shape and structure of the undisturbed soil will be destroyed during the squeezing process. In addition, this soil sampling method can generally only take one soil sample at a time, and the sampling efficiency is low, which makes it difficult to meet the needs of geotechnical tests.

[0003] For example, the publication number CN203275121 U disclosed an original soil extractor on November 6, 2013, including a connecting rod, a handle fixedly connected to the top of the connecting rod, a soil container fixedly connected to the bottom, and the soil container opening downwards, characterized in that: the soil container is circular in shape, hollow inside, with cutting edges around the bottom, the soil storage is circular in shape, hollow inside, and screw interfaces are symmetrically arranged on the top of the soil storage; screws are arranged inside the opening groove. The above-mentioned disclosed soil extractor needs to be manually moved and pressed down to realize soil extraction when in use, which is slow in soil extraction and poor in practicality.

[0006] As a further solution of the utility model, the driving assembly includes an air tank, a ventilation pipe, a cylinder and an air compressor.

The piston of the cylinder is connected to the connecting rod.

[0007] As a further solution of the utility model, the soil taking tube is provided with a soil taking plate, the soil taking plate is threadedly matched with the pressure rod, and the connecting rod is threadedly matched with the pressure plate.
