Convenient soil sampling device special for geological exploration

Abstract

The invention relates to the related field of geological prospecting equipment, and discloses a convenient soil sampling device special for geological prospecting, wherein the device comprises a main body; a power cavity is arranged in the main body, a telescopic rod cavity with a downward opening is arranged at the lower side of the power cavity, a sampling power cavity is arranged at the right side of the power cavity, and a sampling through cavity is communicated with the upper side of the sampling power cavity; a cover plate limiting cavity with an upward opening is formed in the upper side of the sampling through cavity in a communicating mode, rotary drilling can be conducted on the ground through rotation of a ground drilling unit, and the structural integrity of a pre-collected soil layer is reserved to the maximum extent; through limiting contact of a depth limiting block with the ground, the device can automatically perform soil collection work on the ground when drilling to a set depth, the device automatically stops after sampling is completed, and manpower and material resources are saved; a soil sample can be easily taken out by pulling a pull ring upwards, so the collected soil is more convenient to take out, the comprehensive efficiency of soil sampling work is improved, and the height error of sampled soil is reduced.

Description

technical field [0001] The invention relates to the related field of geological exploration equipment, in particular to a convenient soil sampling device specially used for geological exploration. Background technique [0002] Most of the existing soil collection machines implement the function by impacting downwards and nailing into the sampling container, which will damage the structure of the soil layer to be sampled to a certain extent, and cause a certain degree of compression to the soil due to the impact and vibration Or slippage, which affects the accuracy of soil sampling. When the sampling work is carried out, many people need to work together, which requires considerable labor costs. After the sampling is completed, it is more laborious to take out the sampling container, which affects the overall work efficiency. Contents of the invention [0003] The purpose of the present invention is to provide a special convenient soil sampling device for geological explora...

[0002] Most of the existing soil collection machines implement the function by impacting downwards and nailing into the sampling container, which will damage the structure of the soil layer to be sampled to a certain extent, and cause a certain degree of compression to the soil due to the impact and vibration Or slippage, which affects the accuracy of soil sampling. The sampling work requires the cooperation of many people, which requires considerable labor costs. After the sampling is completed, it is more laborious to take out the sampling container, which affects the overall work efficiency.
