Description

Technical Field

[0001] This utility model relates to the field of geological exploration technology, and in particular to a geological exploration sampling device. Background Technology

[0002] Geological exploration is a survey and research activity that uses various means and methods to investigate and explore the geology, determine suitable bearing strata, determine the foundation type based on the bearing capacity of the bearing strata, and calculate foundation parameters. It involves investigating and researching the geological conditions of rocks, strata, structures, minerals, hydrology, landforms, etc. in a certain area. Geological exploration often requires taking samples of soil from below the surface and analyzing them.

[0003] Currently, in the geological exploration sampling process, samplers are usually used for sampling. During the sampling process, because the inner side of the sampler is relatively smooth, when the sampler is pulled out after being inserted into the ground, the geological sample is easy to slip out of the sampler, causing the sample to scatter and affecting the sampling. Therefore, improvements are needed. Utility Model Content

[0023] The technical solutions of the present utility model will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.

[0024] The following describes a geological exploration sampling device according to an embodiment of the present invention in detail with reference to the accompanying drawings.

[0025] Example 1

[0026] For easier understanding, please refer to Figures 1 to 4 An embodiment of a geological exploration sampling device provided by this utility model includes a sampling tube 1, a handle 2 fixedly connected to the top of the sampling tube 1, a drill bit assembly at one end of the sampling tube 1, and a material ejection assembly in the middle of the sampling tube 1.

[0027] The drill bit assembly includes a fixed head 301, a spiral drill bit 302, a fixed groove 303, a fixed bearing 304, a fixed ring 305, and several elastic baffles 306. The fixed head 301 is threaded to the bottom of the sampling tube 1. The spiral drill bit 302 is located at one end of the fixed head 301. The fixed groove 303 is formed inside one end of the spiral drill bit 302. The fixed bearing 304 is fixedly installed inside the fixed groove 303. The fixed ring 305 is fixedly installed inside the fixed bearing 304. One end of several elastic baffles 306 is fixedly connected to one end of the fixed ring 305. One end of the spiral drill bit 302 is fixedly installed at one end of the fixed head 301 by bolts. Several elastic baffles 306 are arranged in a ring array at one end of the fixed ring 305. The ends of several elastic baffles 306 near the fixed ring 305 are recessed towards the ends away from the fixed ring 305. The inner diameter of the spiral drill bit 302 and the fixed head 301 is the same as the inner diameter of the sampling tube 1.

[0028] It should be noted that by setting an elastic baffle 306, which is fixed between the fixed head 301 and the auger drill bit 302 by a fixed ring 305 and a fixed bearing 304, the auger drill bit 302 is used to drill into the ground for sampling. The sample enters the sampling tube 1 through the elastic baffle 306. During the sampling process, the elastic baffle 306 can be locked on the outside of the sample. The fixed bearing 304 can rotate but does not rotate with it during drilling, thus avoiding twisting and breaking the bottom sample. When the sampling device is pulled out, the elastic baffle 306 will clamp the geological sample to prevent it from falling and scattering.

[0029] Example 2

[0030] In some embodiments, such as Figure 4As shown, the unloading assembly includes a chute 401, a handle 402, a slide rod 403, and a push plate 404. The chute 401 is opened on one side of the sampling tube 1. The handle 402 is slidably connected to the outside of the sampling tube 1. The slide rod 403 is fixedly installed on the inside of the handle 402. The push plate 404 is fixedly installed in the middle of the slide rod 403. The inner diameter of the handle 402 matches the outer diameter of the sampling tube 1. The slide rod 403 is slidably connected to the inside of the chute 401, and the diameter of the slide rod 403 matches the width of the chute 401.

[0031] It should be noted that by setting the push plate 404, which is located inside the sampling tube 1, after sampling, the drill bit assembly is disassembled, and the handle 402 is held. At this time, pushing the handle 402 will push the sample inside the sampling tube 1 out using the internal push plate 404, making it convenient to remove the sample.

[0032] Working principle: During use, the auger bit 302 is used to drill into the ground for sampling. The sample enters the sampling tube 1 through the elastic baffle 306. During the sampling process, the elastic baffle 306 can be locked on the outside of the sample. It can rotate using the fixed bearing 304, but it does not rotate with the sample during drilling, thus avoiding breaking the sample at the bottom. When the sampling device is pulled out, the elastic baffle 306 will clamp the geological sample to prevent it from falling and scattering. After sampling, the drill bit assembly is disassembled. By holding the handle 402, pushing the handle 402 will push the sample out of the sampling tube 1 using the internal push plate 404, making it easy to remove the sample.

[0033] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
