Description

Technical Field

[0001] The utility model relates to the technical field of address exploration devices, in particular to a geological exploration sampling device. Background Art

[0002] Geological exploration is a survey and research activity that uses various means and methods to survey and detect geology, determine the appropriate bearing layer, determine the foundation type based on the bearing capacity of the bearing layer, and calculate the foundation parameters. Geology is one of the seven natural sciences, mainly studying the earth and its causes and evolution. It has a wide range of practical applications, including earthquake prediction, search and exploration of various minerals, catastrophic landslides, evolution of paleontology, etc. In geological exploration, sampling is a common method of exploration. When sampling, undisturbed soil sampling is generally carried out through sampling drills and sampling tubes, which is suitable for sampling of measured geological profiles and can more completely retain the distribution information of material components. When encountering hard objects such as stones, sampling must be carried out in conjunction with drilling.

[0003] The sampling drill used in the above-mentioned sampling operation is generally composed of a drill body and a handle part. When encountering harder stones, it needs to be used in conjunction with a drilling device. This requires carrying a variety of sampling tools in a one-time sampling operation, which is not only inconvenient to carry but also the sampling operation process is relatively cumbersome. For this reason, we propose a geological exploration sampling device. Utility Model Content

In conjunction with the pile frame 101 and the drill rod 201, the motor 104 connected to the motor frame 103 can assist in providing driving force during the sampling process, and assist the drill frame 2 to rotate, thereby providing convenience for the sampling process.

[0029] like Figure 2-3 As shown, the drill rack 2 includes a drill rod 201, and sampling grooves 202 are provided on both sides of the drill rod 201, an insertion rod 203 is connected to one end of the drill rod 201, and a clamping surface 204 is provided on both sides of the insertion rod 203, a plug hole 205 is provided at the middle end of the clamping surface 204, and a drill bit 206 is provided at the other end of the drill rod 201, and a threaded frame 207 is distributed around the outer wall of the drill bit 206;

[0030] In order to improve the sampling convenience and portability of this sampling device, Figure 1-3 As shown, the drill rod 201 of the sampling device can be combined and disassembled with the pile frame 101 through an insertion rod 203 at one end. When sampling softer soil, the bottom end of the drill rod 201 can be directly inserted into the soil through the sampling grooves 202 on both sides and then pulled out to take samples. When encountering harder soil, the drill head 3 can be rotated and removed to expose the drill bit 206.
