Description

Technical Field

[0001] The utility model relates to the technical field of rock and soil exploration, in particular to a sampling sample crushing device for rock and soil exploration. Background Art

[0002] The main tasks of geotechnical investigation include ascertaining the geological, environmental characteristics and geotechnical engineering conditions of the construction site; determining the physical and mechanical properties of the soil layer of the building foundation; evaluating the stability and bearing capacity of the foundation; dealing with adverse factors; comprehensively evaluating and making suggestions; and compiling a survey report.

[0003] In the work of determining the physical and mechanical properties of foundation soil and understanding geotechnical engineering conditions, it is necessary to drill and collect samples on site. When the samples are taken into the laboratory for physical, chemical and mechanical analysis, the large samples need to be crushed. The existing sample crushing tools mainly crush the samples by impact or extrusion from top to bottom. After the samples are crushed, they need to be picked up. The edges of the storage devices have a certain degree of protection, which makes it inconvenient to clean the samples squeezed into powder or fine particles. Therefore, a crushing device that is convenient for sample collection and storage and easy to clean is needed. Utility Model Content
