[0002] Geological testing is a crucial part of geological work. It analyzes the physical properties, chemical composition, and internal structure of geological samples such as rocks, minerals, soil, water, and gases to provide scientific and accurate data support for geological research, mineral resource exploration, environmental assessment, and engineering construction. Nowadays, in order to understand the geological conditions accurately, fixed-point sampling of the geological environment is generally carried out before the experiment.

The load-bearing positioning frame is equipped with electric casters on its side.

[0012] According to the above technical solution, a clip fixing sleeve is installed inside the synchronous cooling tank, and a filter integrated mesh frame is sleeved inside the clip fixing sleeve. The synchronous cooling barrel has symmetrically provided combined limiting grooves on its side end and a combined limiting hole on its top end; A multi-hole limiting rod is inserted inside the combined limiting hole; A spring-loaded rod is symmetrically installed at one end of the inner side of the combined limiting groove, and a card-inserting limiting frame is installed at one end of the spring-loaded rod.

[0013] According to the above technical solution, the processing screw side end is connected to the bottom support limiting frame side end through the screw seat, and the card insertion limiting frame is inserted and connected to the multi-hole limiting rod; The input terminals of the clamping hydraulic cylinder, hydraulic motor, load-bearing hydraulic cylinder, and electric omnidirectional wheel are all electrically connected to the input terminal of an external controller.

[0014] According to the above technical solution, a sampling method for geological experimental testing includes the following steps: S1. Sampling preparation: The horizontal support limit frame is moved and raised by the load-bearing hydraulic cylinder, load-bearing clamping frame and electric caster, and the equipment is placed at the sampling position. The bottom support limit frame is raised and lowered by the hydraulic motor and the processing screw, and the rising clamping frame is raised and lowered by the rising hydraulic cylinder. The clamping fixing sleeve, the pressing combination tube and the cutting processing tube are fitted one by one to realize the combination preparation and positioning preparation before sampling. S2. Sampling and processing: The rotary motor, processing gear and linkage gear drive the locking sleeve, pressing combination tube and cutting processing tube to rotate, cutting and sampling the geological layer.

The lifting hydraulic cylinder and processing screw are used to perform pressing and cutting processing to achieve continuous long-distance cutting and sampling processing. S3. Sample collection: The reciprocating electric slide rail drives the fitting limiting block and the fixed electromagnet to fit against the side end of the pressing combination tube.

Sample Classification: Staff members independently retrieve and store the required samples according to the required stratum depth, thus achieving sample classification.

[0015] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a scientific and reasonable structure and is safe and convenient to use. 1. Equipped with an inlet / outlet assembly, the rotating motor, processing gear, and linkage gear drive the locking sleeve, pressing combination tube, and cutting processing tube to rotate. A hydraulic motor drives the processing screw to push the bottom support limiting frame and the rising locking frame downwards, causing the cutting processing tube and pressing combination tube to gradually rotate and cut into the desired geological location for sampling. Coolant is injected into the inner side of the series cooling chamber via an extraction pump and a pressure sealing tube, and reflux is achieved with a return limiting tube. A forced cooler further cools the coolant in the synchronous cooling tank. This internal circulation and simultaneous cutting process prevents coolant from being directly injected into the formation, thus avoiding sample contamination during sampling. It also prevents high temperatures from damaging the formation structure, ensuring sampling accuracy and sample quality. The lifting hydraulic cylinder drives the lifting clamping frame to rise and fall, which in turn drives the bottom support limiting frame to rise and fall with the help of the hydraulic motor and the processing screw. The combination clamping block and combination clamping hole are used to clamp and connect the clamping fixing sleeve, the pressing combination tube and the cutting processing tube, and the pressing sealing tube and the return limiting tube between the pressing combination tube and the cutting processing tube to achieve the combination connection of the sampling pipeline. This allows for rapid combination and adjustment during long-distance sampling. The fixed sliding electric slide rail drives the fitting limiting block and the fixing electromagnet to adhere to the side end of the pressing combination tube, so that the fixing electromagnet magnetically fixes the pressing combination tube. The processing hydraulic cylinder drives the processing clamping plate and the fitting limiting block to pull the pressing combination tube and the cutting processing tube upward. Through continuous and repeated pulling and rising, the sample rises at a uniform speed, avoiding the breakage of the sample and ensuring the speed and quality of long-distance sampling and processing.

[0016] 2. Equipped with a linkage component, the load-bearing clamping frame and the cross brace limiting frame are moved via electric casters. The load-bearing hydraulic cylinder moves the load-bearing clamping frame, adjusting the distance between them. The support position of the electric casters is adjusted according to the sampling environment to ensure the accuracy of overall support and limiting, preventing equipment misalignment during sampling and thus improving sampling accuracy. A multi-hole limiting rod is inserted into the combined limiting hole, and a spring-loaded clamping rod drives the inserting clamping frame to the side of the multi-hole limiting rod. The inserting clamping sleeve and the integrated filter screen filter the coolant, enabling rapid coolant replacement during sampling and ensuring cooling stability. A clamping hydraulic cylinder drives the clamping operating block and anti-slip positioning pad to clamp and limit the lowering combined tube and the lower cutting tube, ensuring accurate and stable clamping and fixing during sample discharge and separation. This guides the sample, preventing delamination and breakage, and increasing the quantity and convenience of sampling.

[0017] In summary, by cooperating with the entry and exit components and the linkage components, and through multi-stage rapid correction, coordinated locking and limiting, synchronous lifting and squeezing, and cooling protection limit, the required strata can be accurately cut and sampled during geological sampling. This avoids sample distortion caused by cutting position deviation, coolant mixing, and outgoing breakage, thereby improving the accuracy and speed of sampling. Attached Figure Description

[0023] like Figure 10 As shown, the present invention provides a technical solution, a sampling method for geological experimental testing, comprising the following steps: S1. Sampling preparation: The horizontal support limit frame 304 is moved and raised by the load-bearing hydraulic cylinder 307, the load-bearing clamping frame 308 and the electric universal wheel 309 to place the equipment at the sampling position. The bottom support limit frame 1 is raised and lowered by the hydraulic motor 305 and the processing screw 306, and the rising clamping frame 202 is raised and lowered by the rising hydraulic cylinder 201. The clamping fixing sleeve 206, the pressing combination pipe 207 and the cutting processing pipe 208 are fitted one by one to realize the combination preparation and positioning preparation before sampling. S2. Sampling and processing: The rotary motor 203, processing gear 204 and linkage gear 205 drive the locking sleeve 206, the pressing combination tube 207 and the cutting processing tube 208 to rotate, cutting and sampling the geological layer. The pressing sealing tube 212, the return restricting tube 213, the synchronous cooling tank 214 and the extraction pump 215 are used to cool the pressing combination tube 207 and the cutting processing tube 208. The lifting hydraulic cylinder 201 and the processing screw 306 are used to perform the pressing and cutting process, realizing continuous long-distance cutting and sampling processing. S3. Sample collection: The reciprocating electric slide rail 225 drives the fitting limiting block 226 and the fixed electromagnet 227 to fit against the side end of the pressing combination tube 207. The processing hydraulic cylinder 223 drives the processing clamping plate 224 and the fitting limiting block 226 to pull the pressing combination tube 207 up, realizing the sample lifting and retrieval. The pressing combination tube 207 is separated from the cutting processing tube 208 to realize the rapid sample retrieval and processing. S4. Sample Classification: Staff members independently retrieve and store the required samples according to the required stratum depth, thus achieving sample classification.

[0024] The working principle and usage process of this invention are as follows: During geological sampling, the electric caster 309 drives the load-bearing positioning frame 308 and the cross brace limiting frame 304 to move, moving the cross brace limiting frame 304 to the sampling position. The load-bearing hydraulic cylinder 307 drives the load-bearing positioning frame 308 to move, adjusting the distance between the load-bearing positioning frame 308 and the cross brace limiting frame 304. The support position of the electric caster 309 is adjusted according to the sampling environment. The lifting hydraulic cylinder 201 drives the lifting positioning frame 202 to rise, raising it to its highest point. Then, the hydraulic motor 305 drives the processing screw 306 to rotate. 306 drives the bottom support limiting frame 1 to rise along the horizontal support limiting frame 304, raising the bottom support limiting frame 1 to the highest position, fitting the combination locking block 210 on the side end of the downward pressure combination pipe 207 onto the side end of the combination locking hole 209 on the side end of the locking fixing sleeve 206, fitting the downward cutting treatment pipe 208 onto the bottom end of the downward pressure combination pipe 207, so that the combination locking block 210 on the side end of the downward cutting treatment pipe 208 fits onto the side end of the combination locking hole 209 on the side end of the downward pressure combination pipe 207, and inserts the pressure sealing pipe 212 and the return limiting pipe 213 at the bottom end of the downward pressure combination pipe 207 into the inside of the downward cutting treatment pipe 208, realizing the combination connection of the sampling pipe; The synchronous cooling tank 214 is inserted into the inner side of the locking bracket 216. The pressing sealing tube 212 and the return restricting tube 213 are inserted into the top of the side end of the pressing combination tube 207. The oscillating motor 218 drives the sealing cover 217 to rotate. The separation hydraulic cylinder 219 drives the oscillating motor 218 and the sealing cover 217 to move down to the top of the synchronous cooling tank 214. The multi-hole limiting rod 314 is inserted into the inner side of the combination limiting hole 313. At this time, the spring pressing rod 315 drives the insert card limiting frame 316 to move along the combination limiting groove 312, so that the insert card limiting frame 316 is inserted into the side end of the multi-hole limiting rod 314, so that the sealing cover 217 and the synchronous cooling tank 214 are fitted and sealed together, realizing the preparation before sampling. The rotary motor 203 drives the processing gear 204 to rotate along the rising clamping frame 202. The processing gear 204 drives the linkage gear 205 to rotate. The linkage gear 205 drives the clamping fixing sleeve 206, the pressing combination tube 207 and the cutting processing tube 208 to rotate along the bottom support limiting frame 1 and the cross support limiting frame 304. The hydraulic motor 305 drives the processing screw 306 to rotate, pushing the bottom support limiting frame 1 to move down along the cross support limiting frame 304. The rising hydraulic cylinder 201 drives the rising clamping frame 202 to press down, so that the cutting processing tube 208 and the pressing combination tube 207 gradually rotate and cut into the geological location where the sample needs to be taken, realizing the cutting and sampling processing. When deeper sampling is required, after the pressing combination pipe 207 is embedded in the ground, the processing gear 204 drives the linkage gear 205 to rotate in the opposite direction, causing the locking sleeve 206 to separate from the pressing combination pipe 207. Simultaneously, the lifting hydraulic cylinder 201 drives the lifting locking frame 202 to rise, and the processing screw 306 drives the bottom support limiting frame 1 to rise, inserting the new pressing combination pipe 207 into the inner side of the pressing combination pipe 207 embedded in the ground. The rising combination process and drilling sampling process are repeated to achieve deeper pressing sampling. During the sampling process, the synchronous cooling tank 214 is extracted through the extraction pump 215 and the pressure sealing pipe 212. 2. The coolant in the synchronous cooling tank 214 is injected into the inner side of the serial cooling chamber 211. It is then used in conjunction with the return flow restriction pipe 213 for return flow treatment and with the filter integrated mesh frame 311 at the top of the plug-in fixing sleeve 310 for interception and filtration. This achieves cooling treatment of the drilling down-pressure combination pipe 207 and the down-cutting treatment pipe 208, while preventing the coolant from being injected into the ground and causing excessive water content in the sample, thus ensuring the stability and quality of the sample. During the continuous cooling process, the coolant in the synchronous cooling tank 214 is forcibly cooled by the forced cooler 220, thereby ensuring that the coolant remains at a low temperature and preventing the coolant from overheating and affecting the cooling effect. After sampling is completed, the lifting hydraulic cylinder 201 and the lifting clamping frame 202 pull the pressing combination tube 207 and the cutting processing tube 208 upward. Then, the hydraulic motor 305 drives the processing screw 306 to drive the bottom support limiting frame 1 upward. At this time, the electric universal wheel 309 moves and adjusts the position of the cross support limiting frame 304, so that the pressing combination tube 207 moves to the bottom of the fitting limiting block 226. Then, the reciprocating electric slide rail 221 drives the reciprocating operating frame 222 to move along the bottom support limiting frame 1.
