Soil sampling device for geological exploration

Abstract

The invention discloses a soil sampling device for geological exploration, and relates to the technical field of geological exploration appliances, the soil sampling device comprises a bottom plate, stand columns vertically arranged on two sides of the top surface of the bottom plate and a lifting plate horizontally arranged between the upper parts of the stand columns, stabilizing cylinders are arranged on two sides of the top surface of the lifting plate, and a sampling drill cylinder is arranged in each placing cylinder; a lifting assembly is arranged in the lifting cavity; a driving assembly is arranged on the mounting frame; a cooling assembly is arranged in the connecting cylinder; a transmission mechanism is arranged at the bottom of the mounting seat; through cooperation of the sampling drilling barrel, the mounting base and the transmission mechanism, the sampling drilling barrel can be conveniently subjected to rotary cutting and downward drilling, stone existing in a soil body can be conveniently crushed, meanwhile, intermittent water supplementing, cooling and lubricating effects can be achieved on the sampling drilling barrel which is rotationally drilled downwards, the service life of a crushing cutting ring at the bottom of the sampling drilling barrel is conveniently prolonged, and the sampling drilling barrel is convenient to use. Soil bodies with different depths can be conveniently collected, classified and sorted, and the efficiency and accuracy of soil sampling are greatly improved.

Description

technical field [0001] The invention relates to the technical field of geological prospecting tools, in particular to a soil sampling device for geological prospecting. Background technique [0002] Geological prospecting is the discovery of mineral deposits with industrial significance in the general survey of mineral resources. In order to ascertain the quality and quantity of mineral products, as well as the technical conditions for mining and utilization, provide mineral reserves and geological data required for mine construction design, and analyze rocks in a certain area. Investigate and study geological conditions such as stratum, structure, minerals, hydrology, and geomorphology; [0003] At present, the existing rapid soil sampling device is inconvenient to break the rocks at the bottom of the sampling during use, which is easy to damage the sampler, and the sampling drill tube is prone to overheating under the condition of long-term rotary drilling, which affects t...

Problems solved by technology

[0003] At present, the existing rapid soil sampling device is inconvenient to break the rocks at the bottom of the sampling during use, which is easy to damage the sampler, and the sampling drill tube is prone to overheating under the condition of long-term rotary drilling, which affects the quality of the sampling drill. The friction force of the contact between the cylinder and the soil causes greater resistance when the sampling drill cylinder is drilled down, and it is not convenient to classify and sort the soil samples; therefore, the above problems need to be improved.
