Technical Field

[0001] The invention belongs to the technical field of geological exploration, and in particular relates to a crushing sampling device for mine geological exploration and a use method thereof. Background Art

[0002] Mine geological exploration is a key step in the development of mineral resources. Through various means and methods, in-depth geological exploration and detection are carried out to determine the appropriate bearing layer, evaluate the bearing capacity of the foundation, calculate the basic parameters, and provide a scientific basis for the subsequent mine construction / design. The process of mine geological exploration not only involves comprehensive investigation and research on geological conditions such as rocks, strata, structures, minerals, and landforms, but is also directly related to the evaluation of mineral reserves and the determination of technical conditions. It is of decisive significance for the effective development and utilization of mineral resources.

[0003] When conducting geological exploration of mines, crushing and sampling is an indispensable and important link. The quality of crushing and sampling is directly related to the accuracy and reliability of the exploration results. However, due to the complex and changeable terrain of mines, such as high mountains, deep valleys, steep slopes and other terrain conditions, sampling work has brought great challenges. Traditional sampling devices / equipment are often difficult to adapt to these complex environments, which can easily lead to problems such as sampling layer deviation, large sampling deviation, and inaccurate measurement. It not only increases the difficulty of exploration work, but also may affect the accuracy and reliability of exploration results, and thus affect the smooth progress of mine construction and production. In addition, the existing crushing sampling devices also have certain limitations when dealing with different mining environments. Especially in some crushing sampling locations where the ground cannot provide sufficient support, the existing equipment is often difficult to operate stably, or even unable to complete the sampling task, which not only limits the scope and depth of exploration work, but also increases the risk and cost of exploration work.

[0025] 2. The drill bit, sampling barrel and transmission main shaft of the present invention are connected by screws, which is convenient for replacing drill bits and sampling barrels of different specifications to meet different exploration needs; and the first through hole, the second through hole, the first threaded hole and the second threaded hole are coaxially arranged, so that the device can cancel the setting of the sampling barrel as needed. For example, when the geological hardness is high, the drill bit can be directly connected to the transmission main shaft to crush the geological material, and then the sampling barrel can be connected to the transmission main shaft to sample the crushed geological material. The overall adjustability is high and the adaptability is good.

[0026] 3. The present invention arranges spiral crushing protrusions on the drill bit, which has a strong crushing effect and is applicable to rocks of various hardnesses; a sampling barrel is arranged on the crushing drill bit, and a sampling scraper is arranged on the outside of the sampling barrel, and a sampling groove is opened on the side wall thereof. After the drill bit crushes the rock, the sampling scraper can scrape and guide the crushed rock into the sampling barrel through the sampling groove, so as to realize the collection of rock samples; wherein, the uniform distribution of the sampling grooves and the sampling scrapers ensures the uniformity and comprehensiveness of the sample collection.

[0027] 4. The driving assembly of the present invention can be a combination of a motor and an electric telescopic rod. The rotation of the motor drives the transmission main shaft, and the electric telescopic rod controls the up and down movement of the motor to achieve the lifting and lowering of the drill bit and the sampling tube. The operation is simple and convenient, and the efficiency of crushing and sampling is high.

[0028] 5. The driving assembly of the present invention can also be a motor and a first guide limit groove body. The rotation of the motor drives the transmission main shaft. The operator holds the pressing handle and presses the motor, so that the first slider on the motor base slides in the first guide limit groove body to realize the lifting and lowering of the crushing drill bit and the sampling tube. The first guide limit groove body guides and limits the movement of the motor to ensure its stability during the lifting process. The operation is simple, and the crushing sampling process is easy to control.

[0029] 6. The driving assembly of the present invention can also be a combination of an adjusting handwheel and a mechanical transmission system (bevel gear set and thread set). The rotating adjusting handwheel drives the external threaded rod to rotate under the action of the active bevel gear, and the internal threaded cylinder drives the transmission main shaft to rise and fall under the action of the driven bevel gear, the thread (the internal threaded cylinder and the external threaded rod are connected by threads), the second slider and the second guide limit groove body; wherein, the second guide limit groove body guides and limits the movement of the internal threaded cylinder; this structure does not rely on electricity, has a wide range of applications, and the crushing sampling process is controllable.

[0030] In summary, the crushing and sampling device for mine geological exploration provided by the present invention has components that are tightly connected and easy to disassemble, which is convenient for maintenance and replacement at the exploration site, and reduces the volume and weight of the device, making it easy to carry and transport; the precise sampling and crushing process helps to obtain more accurate geological data, providing a more reliable basis for mine construction and design; the flexible support structure and diversified driving methods enable the device to cover a wider geological exploration area, improving the comprehensiveness and accuracy of the exploration.

[0048] In this embodiment, three telescopic support bodies are provided, and the three telescopic support bodies are evenly arranged axially around the reference ring 1, providing better stability and supporting force distribution, further improving the ability of the entire device to be applicable to different terrains, and expanding the scope of application of the device while ensuring sampling accuracy.

[0049] like Figure 4 , 5 As shown, the drilling sampling mechanism is fixedly arranged on the adjusting base frame, and the drilling sampling mechanism is used for drilling and sampling.

[0050] The drilling sampling mechanism includes a driving assembly 19, a drill bit 13, a sampling barrel 14, and a transmission spindle 18. The driving assembly 19 is fixed on the reference ring 1. The reference ring 1, the transmission spindle 18, the drill bit 13, and the sampling barrel 14 are coaxially arranged.

A second through hole is provided at the bottom of the second connecting groove 2, and the second through hole passes through the lower end surface of the sampling barrel 14. A first threaded hole corresponding to the first through hole is provided on the upper end surface of the sampling barrel 14, and a second threaded hole corresponding to the second through hole is provided on the upper end surface of the drill bit 13. The transmission main shaft 18, the sampling barrel 14, and the drill bit 13 can be connected by means of a screw 17 passing through the first through hole and the second through hole.

[0052] In addition, the first through hole, the second through hole, the first threaded hole, and the second threaded hole are coaxially arranged, so that the transmission main shaft 18 can be directly connected to the drill bit 13. For the case of high geological hardness, the drill bit 13 can be directly connected to the transmission main shaft 18 to crush the geology, and then the sampling tube 14 is connected to the transmission main shaft 18 to sample the crushed geology. The overall adjustability is high and the adaptability is good.

[0053] like Figure 7 As shown, the wall of the sampling barrel 14 is provided with a plurality of sampling grooves 15, and the outer wall of the sampling barrel 14 is provided with a plurality of sampling scrapers 16 corresponding to the plurality of sampling grooves 15, and the sampling scrapers 16 are in an arc-shaped curved structure, so that the rock sample can be scraped into the sampling barrel 14 by the sampling scrapers 16, and the drill bit 13 is provided with a spiral crushing protrusion along the circumferential direction, and the vertical distance between the edge of the spiral crushing protrusion and the axis of the drill bit 13 is greater than the vertical distance between the edge of the sampling scraper 16 and the axis of the drill bit 13, so that when the drill bit 13 is drilling, the sampling scraper 16 will not interfere with the inner wall of the borehole, and damage to the sampling scraper 16 can be avoided. The arc-shaped curved structure of the sampling scraper 16 is consistent with the rotation direction of the spiral crushing protrusion.

[0054] like Figure 4 As shown, the driving assembly 19 includes a reference plate 12 , a support column is integrally provided at the bottom of the reference plate 12 , the support column is welded to the reference ring 1 , a box body 25 is fixedly provided on the upper surface of the reference plate 12 , and an adjusting hand wheel 26 is provided outside the box body 25 .

[0055] like Figure 6As shown, a connecting frame 27 is fixedly arranged on the top of the box body 25, and a second guide limit groove body 33 is arranged in the box body 25. The top of the second guide limit groove body 33 is fixed on the connecting frame 27, and the bottom of the second guide limit groove body 33 is fixed on the reference plate 12. An internal threaded cylinder 31 is vertically slidably connected to the second guide limit groove body 33, and a plurality of second sliders 32 are fixedly arranged on the outer wall of the internal threaded cylinder 31. The internal threaded cylinder 31 is vertically slidably connected to the second guide limit groove body 33 through the second sliders 32. The lower end of the internal threaded cylinder 31 extends out of the box body 25 and is fixedly connected to the transmission main shaft 18, so that the transmission main shaft 18 can move up and down following the internal threaded cylinder 31.

[0056] An externally threaded rod 30 is threadedly connected in the internally threaded cylinder 31. The bottom of the externally threaded rod 30 extends out of the box body 25 and is slidably connected to the transmission main shaft 18. The externally threaded rod 30 and the transmission main shaft 18 cannot rotate relative to each other. A driven bevel gear 28 is set on the top of the externally threaded rod 30. The rotating shaft of the adjusting hand wheel 26 extends into the box body 25 and is provided with a driving bevel gear 29. The driving bevel gear 29 is meshed with the driven bevel gear 28.

[0057] It can be understood that after turning the adjusting hand wheel 26, the active bevel gear 29 drives the driven bevel gear 28 to rotate, thereby causing the externally threaded rod 30 to rotate. The rotation of the externally threaded rod 30 can drive the drill bit 13 on the transmission main shaft 18 to rotate. In addition, during the rotation of the externally threaded rod 30, the internally threaded tube 31 will move vertically under the action of the thread, thereby driving the drill bit 13 on the transmission main shaft 18 to move vertically, thereby realizing the downward drilling or upward extraction of the drill bit 13. By manually controlling the lifting and rotation of the drill bit 13, the crushing sampling process is easy to control.

[0058] The method of using the crushing sampling device for mining geological exploration is as follows:

[0059] Step 1: Place the adjustment base stably at the sampling position:

[0060] If the adjustment base can be placed stably on the current ground, adjust the angle of the support trough 4, the angle between the support trough 4 and the support rod 7, and the length of the telescopic support body so that the placement plate 10 is close to the ground, use the first locking member 9 to fix the support rod 7 to the support trough 4, use the second locking member 11 to fix the support rod 7 to the placement plate 10, and fix the placement plate 10 to the ground with the anchor bolts;

[0061] If the adjustment base cannot be placed stably on the current ground, rotate part of the telescopic support body, and fix the part of the telescopic support body to the reference ring 1 through the connecting hole 3 and the connecting plate 5, and adjust the angle between the support groove 4 and the support rod 7 and the length of the telescopic support body, so that the placement plates 10 of part of the telescopic support body are fixed on the wall or slope, the placement plates 10 of other telescopic support bodies are fixed on the ground, or the placement plates 10 of all telescopic support bodies are fixed on the slope;

[0062] Step 2: Manually turn the adjusting hand wheel 26 to control the drill bit 13 to drill downward, and the sampling scraper 16 scrapes the rock sample into the sampling tube 14. After the sampling is completed, reverse the adjusting hand wheel 26 to control the drill bit 13 to be pulled out upward.

[0063] Example 2

[0064] Compared with the embodiment 1, the difference of the embodiment 2 is that the structure of the driving component 19 is different. Figure 8 , 9 As shown, the driving assembly 19 includes a reference plate 12 , on which two electric telescopic rods 21 are fixedly arranged, on which a motor 20 is arranged, and an output shaft of the motor 20 is arranged vertically downward and fixedly connected to the transmission main shaft 18 .

[0065] It is understandable that the drill bit 13 can be driven to rotate by the motor 20, and the drill bit 13 can be driven to rise and fall by the electric telescopic rod 21, so the drill bit 13 can be drilled downward and pulled upward by the motor 20 and the electric telescopic rod 21.

[0066] Example 3

[0067] Compared with the embodiment 2, the difference of the embodiment 3 is that the structure of the driving component 19 is different. Fig.10 , 11 The driving assembly 19 includes a reference plate 12, two first guide limit slots 23 are fixedly arranged on the reference plate 12, a motor 20 is vertically slidably arranged on the first guide limit slots 23, first sliders 24 are fixedly arranged on both sides of the motor 20, the motor 20 is vertically slidably connected to the first guide limit slots 23 through the first sliders 24, the output shaft of the motor 20 is vertically arranged downward and fixedly connected to the transmission main shaft 18, and a pressing handle 22 is arranged on the top of the motor 20.

[0068] It is understandable that the drill bit 13 can be driven to rotate by the motor 20, and the drill bit 13 can be driven to rise and fall by manually pressing down or lifting up. The rise and fall of the drill bit 13 can be manually controlled, so that the crushing sampling process is easy to control.

[0069] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
