Description

Technical Field

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

[0002] Geological sampling refers to the process of collecting representative samples from specific geological bodies, strata, rocks, etc., in geological exploration, research and other work. Soil samples are collected from the surface or at different depths for soil composition analysis, land quality evaluation, etc. In existing geological sampling, professional sampling equipment is usually used to drill and sample soil layers.

[0003] When conducting geological soil sampling operations, the drilling device must first be precisely moved to the predetermined position before starting the drilling rig. At this time, the power output of the drilling rig drives the drill rod and drill bit to rotate synchronously and gradually drill downwards to collect soil samples. However, in the actual drilling process, the sampling device is prone to shaking. This is mainly because the friction between the drill bit and the soil is uneven during drilling, which generates periodic impact forces. At the same time, the operation of the drilling rig itself will also cause a certain degree of vibration, making it difficult for the drill rod to maintain stability and gradually deviating from the originally set drilling position. Once the drill rod deviates, the soil samples collected later may not originate from the target strata or geological body, making the samples unable to accurately reflect the geological characteristics of the target area. The data obtained will deviate from the actual situation, leading to misleading results in the entire geological research. To address this, we propose a geological sampling device.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1

[0021] Please see Figures 1 to 4 This utility model provides a technical solution: a geological sampling device, including a base 1, four jacking mechanisms 2 fixedly connected to the top of the base 1, two fixing blocks 3 fixedly connected to the top of the base 1, two L-shaped blocks 301 slidably connected inside the fixing blocks 3, a fixing plate 302 fixedly connected inside the fixing blocks 3, four telescopic columns 4 fixedly connected to the outside of the fixing plates 302, springs 401 sleeved on the outside of the telescopic columns 4, a top block 402 fixedly connected to the outside of every two telescopic columns 4, a limiting plate 5 slidably connected inside the fixing blocks 3, a slot 501 inside the limiting plate 5, and a protective plate fixedly connected to the top of the limiting plate 5. 502. The four corners of the base 1 are fixedly connected with casters 6. Two fixing blocks 3 are symmetrically distributed on the top of the base 1. The bottom of the protective plate 502 is in contact with the top of the fixing blocks 3. The limiting plate 5 is externally slidably connected to the inside of the base 1. The L-shaped block 301 is externally slidably connected to the inside of the limiting plate 5. The top block 402 then pushes the L-shaped block 301, so that the L-shaped block 301 slides inside the slot 501 inside the limiting plate 5, so that the L-shaped block 301 and the slot 501 are engaged. This not only limits the base 1 and the casters 6 to prevent the device from moving during drilling, but also improves the overall stability of the device.

[0022] Four jacking mechanisms 2 are fixedly connected to a placement plate 201 at the top. Multiple support columns 202 are fixedly connected to the top of the placement plate 201. A top plate 203 is fixedly connected to the top of the multiple support columns 202. A cylinder 204 is fixedly connected inside the top plate 203. A push rod 205 is fixedly connected to the output end of the cylinder 204. A drilling mechanism 206 is fixedly connected to the bottom of the push rod 205. The top plate 203 and the cylinder 204 jack the push rod 205 downwards, and the push rod 205 drives the drilling mechanism 206 to move downwards.

[0023] A drilling rig 207 is fixedly connected inside the drilling mechanism 206. An installation sleeve 208 is fixedly connected to the output end of the drilling rig 207. A drill rod 209 is installed inside the installation sleeve 208. A drill bit 2010 is fixedly connected to the bottom of the drill rod 209. When the drilling mechanism 206 is started, the drilling rig 207 begins to work. The installation sleeve 208 drives the drill rod 209 and the drill bit 2010 to rotate. The drill bit 2010 drills downward to collect samples.

[0024] One side of the spring 401 is fixedly connected to the outside of the top block 402, and the other side of the spring 401 is fixedly connected to the outside of the fixing plate 302. The outside of the L-shaped block 301 engages with the inside of the slot 501, and the outside of the L-shaped block 301 is in contact with the top block 402. Through the elastic force of the spring 401, the top block 402 can push the L-shaped block 301. The outside of the L-shaped block 301 engages with the inside of the slot 501. When the L-shaped block 301 is engaged in the slot 501, it can limit the position of the limiting plate 5. The outside of the L-shaped block 301 is in contact with the top block 402, and the top block 402 pushes the L-shaped block 301 to slide under the action of the spring 401.

[0025] The working principle of this utility model is as follows: When sampling the geology, firstly, the device is moved to the drilling location by the universal wheels 6 at the bottom of the base 1. Then, the two L-shaped blocks 301 inside the fixing block 3 on one side are pressed towards each other. If the geology is soil, the protective plate 502 can be pressed down to insert into the ground. The protective plate 502, together with the limiting plate 5, is inserted into the drilling ground. Then, the L-shaped blocks 301 are released, causing the top block 402 to push against the L-shaped blocks 301, so that the L-shaped blocks 301 slide in the groove 50 inside the limiting plate 5. Inside 1, the L-shaped block 301 engages with the slot 501, thereby limiting the position of the base 1 and the caster 6 and improving the stability of the device. Then, the jacking mechanism 2 supports the placement plate 201, and the support column 202, together with the top plate 203 and the cylinder 204, pushes the push rod 205 downward, causing the push rod 205 to drive the drilling rig 207 to move downward for drilling. The drilling mechanism 206 is then activated, which, together with the drilling rig 207, the mounting sleeve 208, and the drill rod 209, raises the drill bit 2010 downward for drilling and sampling.

[0026] Example 2

[0027] Please see Figures 2 to 3 In this second embodiment, the other structures remain unchanged. The difference from the first embodiment is that the geological conditions to be drilled are rock strata. In this case, it is necessary to first cut a groove for the matching limiting plate 5 out of the rock strata, then press the two L-shaped blocks 301 inside the fixing block 3 towards each other so that the limiting plate 5 slides into the groove. Then, release the L-shaped blocks 301 so that the L-shaped blocks 301 slide inside the slot 501 inside the limiting plate 5, so that the L-shaped blocks 301 and the slot 501 are engaged.
