Description

Technical Field

[0001] This invention relates to the field of geological exploration technology, specifically to a layered sampling mineral geological exploration device. Background Technology

[0002] In the field of mineral geological exploration, stratified sampling is the core link to obtain information on the distribution of minerals in different strata. Although existing technologies have achieved basic sampling functions, there are still obvious limitations in terms of tensile feed accuracy, sample integrity and adaptability to working conditions.

[0003] The patent CN115839864A disclosed in the patent database adopts a sampling spoon structure built into the drill pipe and recovers the sample through the push head. Although drilling and sampling can be carried out simultaneously, the sampling mechanism can only extend and retract along the drill pipe axis once, which cannot achieve multi-stage precise feeding. It is difficult to adapt to the layered sampling needs of strata of different thicknesses, and the sample is prone to remain and mix inside the drill pipe, which cannot guarantee the purity and integrity of the layered sample. At the same time, it does not have an independent buffer and positioning anchoring structure, which can easily cause the drill bit to be damaged due to impact overload when drilling in complex hard strata, resulting in insufficient equipment stability.

[0004] The geological geophysical sampling equipment disclosed in CN118857830A uses a winch to drive the sampling tube to lift and lower to achieve layered sampling. It relies on manual experience to adjust the sampling position, resulting in low automation. Furthermore, the sampling tube can only achieve single-stage linear feed and cannot complete precise axial extension and retraction while rotating and drilling, making it difficult to match the combined motion requirements of "rotational crushing + layered sampling". In addition, the equipment does not have a buffer protection mechanism designed for the sampling process, and axial impact is easily transmitted to the core transmission components. Long-term operation may lead to structural fatigue failure. Moreover, sample discharge depends on manual operation, which is inefficient and easily damages the original state of the sample.

[0005] The CN216449226U soil and rock sampling device adopts a waist-shaped groove sampling entry structure. Although it optimizes the sample collection channel, the sampling components can only be fed synchronously with the drill bit and cannot independently control the sampling depth and stratification nodes, making it difficult to achieve accurate stratified sampling. Its transmission structure does not adopt a multi-stage tension design, and the feed stroke is limited, which cannot meet the sampling requirements of deep hole exploration. At the same time, it lacks a reliable positioning anchor and buffer shock absorption structure, which is prone to displacement when positioned in rugged terrain. The transmission of drill pressure is unstable during drilling, which further reduces the sampling accuracy and equipment reliability.

[0006] In summary, existing stratified sampling devices generally suffer from problems such as insufficient tensile feed accuracy, easy sample mixing, and lack of buffering and positioning protection, which cannot meet the needs of efficient, accurate, and complete stratified sampling under complex geological conditions. Therefore, there is an urgent need for a new type of mineral geological exploration device that can achieve multi-stage precise extension and retraction, synchronous rotary drilling, sealed sample discharge, and reliable buffering and positioning anchoring functions.

The threaded slide 384 is slidably connected to the outer wall of the limiting slide 36 and threadedly connected to the outer wall of the limiting screw post 39. A servo motor 382 is fixedly connected to the top of the drive box 381. The bottom end of the servo motor 382 is fixedly connected to a connecting shaft 383 by a coupling. The outer wall of the connecting shaft 383 is fixedly connected by bolts. There is a spiral drill bit 388.

Then, the positioning drilling component 38 starts the servo motor 382, ​​which drives the spiral drill bit 388 to rotate via the connecting shaft 383. At the same time, the transmission bevel gear 385 distributes power to the worm gear 386 and worm wheel 387, causing the worm wheel 387 to feed stably along the limiting screw column 39, driving the screw groove slide 384 to move linearly downward along the limiting slide 36, completing the high-precision anchoring drilling and final fixing of the equipment, avoiding deviation during drilling. The buffer docking structure 2 supports the load of the connecting slide 1 through the docking fixing seat 21, and the limiting block 24 restricts lateral sway to ensure coaxiality. During drilling, the damping sliding pair formed by the damping seat 251, the slide plate 252 and the damping slide rod 254 can effectively absorb sudden axial impacts. The buffer spring 258, together with the screw 256 and the adjusting nut 259, can flexibly adjust the preload and buffer stiffness according to the hardness of the formation, so as to smoothly transmit drilling pressure and avoid overload damage to the sampling drill bit 641. During the sampling operation, the multi-stage hydraulic cylinder 4 drives the slide 5 to feed vertically along the connecting slide 1, and the dual-axis motor 7 starts. Power is then transmitted to the driven synchronous pulley 11 via the drive synchronous pulley 8, synchronous belt B13, transmission synchronous pulley 9, and drive shaft 10. The synchronous belt A12 then drives the drive gear ring 633 to rotate. The drive gear ring 633, through transmission gear 634 and drive gear 635, drives the adjusting screw 636 to rotate, causing the tension screw cylinder 637 and tension screw groove cylinder 638 to achieve multi-stage extension and retraction along their respective rectangular grooves. Combined with the rotational torque transmitted by the transmission turntable 61, this drives the drill bit sampling component 64 to complete a composite motion of "rotary drilling + axial feed." After the sampling drill bit 641 breaks the formation, the sampling tube 646 follows the drill. The system gradually collects stratum samples from the corresponding layers. The hydraulic control valve 644 controls the opening and closing of the sampling tube 646 in real time to ensure that samples from different layers do not mix. After the sampling tube 646 has collected samples from the designated layers, the multi-segment tensioning component 63 retracts in stages to lift the drill bit sampling component 64 to the surface. Then, the hydraulic control valve 644 opens the pushing channel and drives the pushing rod 647 to move smoothly down along the inner wall of the sampling tube 646, pushing the collected stratified samples completely into the collection container, completing the precise stratified sampling and sample discharge operation. Finally, all structures are reset in sequence to prepare for the next sampling operation.
