Energy-saving environment detection soil sampling device

Abstract

The invention relates to the technical field of soil sampling, in particular to an energy-saving environment detection soil sampling device which comprises a support, the lower end of a transmission shaft is connected with a drill bit, and the upper end of the transmission shaft penetrates through the support and is connected with a motor; the drill bit comprises an outer drill cylinder, an inner drill cylinder and a rotating shaft. The inner drilling cylinder and the outer drilling cylinder are connected through a connecting structure; an adjusting structure is further arranged between the inner drilling cylinder and the outer drilling cylinder and comprises an upper ring, a middle ring and a lower ring, and the lower ring is connected with the upper ring and the middle ring through elastic devices; a steering structure and a cutter assembly are arranged between the upper ring and the lower ring; a rotating structure is further arranged among the inner drilling cylinder, the outer drilling cylinder and the upper ring to realize synchronous rotation; the limiting strip extrudes the upper ring to realize relative sliding of the inner and outer drilling cylinders and the adjusting structure; according to the device, the cutter extends in different directions in different states in a self-adaptive manner, so that the problem that a drill bit is difficult to drill in different working conditions is solved, large soil is guided and discharged in time, and the self-adaptive and self-adjusting effects of the device are improved.

Description

technical field [0001] The invention relates to the technical field of soil sampling, in particular to an energy-saving soil sampling device for environmental detection. Background technique [0002] In the field of environmental testing, soil sampling devices are often used to sample the soil at a designated location and then perform relevant environmental testing and analysis. However, when drilling and sampling testing of soil layers of different geology and depths, existing The sampling devices in the technology all need to use different drill bits for sampling work, but the existing drill bits are limited by the difference in soil distribution in the soil layer or the interference of gravel in the process of drilling and sampling the soil layer. The soil sampling and drilling depth in the prior art will encounter drilling difficulties due to the different hardness of the soil layer, resulting in the replacement or even damage of the drill bit, which seriously affects th...
