Soil sampling device for geological exploration

Abstract

The invention discloses a soil sampling device for geological exploration, and belongs to the technical field of geological exploration. The soil sampling device for geological exploration comprises a fixed seat, a plurality of tooth columns are annularly and fixedly arranged at the position, relative to a gear, of the lower end of the outer wall of a threaded seat at equal intervals, a connecting column is arranged on the left portion of a movable seat in a penetrating mode, and a plurality of tooth grooves are annularly and structurally formed in the position, relative to the gear, of the outer wall of the connecting column at equal intervals. A rotating groove is formed in the middle of the connecting column in a penetrating mode, a rotating column is arranged in the rotating groove, a fixing shaft is fixedly arranged on the right portion of the top face of the rotating column, the fixing shaft is sleeved with an adapter block, a hydraulic rod is fixedly arranged at the front end of the adapter block, and a sampling assembly is arranged below the connecting column. The pertinence of the sample can be improved, the integrity of the obtained sample can be guaranteed, a worker can know the distribution of soil layers more practically while accurately surveying the geological condition, and the practicability is high.

Description

technical field [0001] The invention relates to the technical field of geological exploration, in particular to a soil sampling device for geological exploration. Background technique [0002] "Geological prospecting" refers to surveying and detecting the geology through various means and methods, determining the appropriate bearing layer, determining the foundation type and calculating the foundation parameters according to the foundation bearing capacity of the bearing layer. Mineral deposits with industrial significance are found in the general survey of minerals. In order to ascertain the quality and quantity of minerals, as well as the technical conditions for mining and utilization, and provide mineral reserves and geological data required for mine construction design, the rocks, strata, structures, In the process of geological exploration work, the staff need to sample the soil in various areas, and then determine the geological structure of the area and the distribut...

Problems solved by technology

[0005] Although the existing device achieves the purpose of sampling at a fixed depth, because it needs to drive the screw conveying rod through the first motor to achieve the sampling effect, the soil samples obtained by it will be broken up, so that the samples obtained by the staff It is the mixed sample of the soil corresponding to the depth, which lacks completeness, and the soil layer in the area cannot be accurately judged. Moreover, the height of the device is fixed, so it is difficult to obtain deeper soil samples. The work has low flexibility, which is not conducive to the smooth progress of the geological exploration work of the staff;
