Description

Technical Field

[0001] The present invention relates to the technical field of mine sampling, in particular to energy-saving mining machinery and equipment. Background Art

[0002] Mining machinery and equipment are a series of mechanical devices used for mining and mineral processing operations. There are many types of them. According to different functions and application scenarios, sampling equipment is an indispensable part of mining equipment. They play an important role in mine exploration, mining and production processes.

[0003] Publication number CN116358924A discloses a sampling device for detection in mining, the technical key points of which are: comprising a fixed frame, a control plate slidably mounted in the inner cavity of the fixed frame along the vertical direction, a sampling barrel rotatably mounted on the bottom wall of the control plate, a plurality of groups of annularly distributed crushing cones arranged around the bottom wall of the sampling barrel, a lifting assembly connected to the control plate provided in the inner cavity of the fixed frame, a control mechanism provided in the sampling barrel, the control mechanism including an automatic unloading assembly and an automatic cut-off assembly, the automatic cut-off assembly including a positioning portion and a cut-off portion;

[0004] The above patent also has the following defects: incomplete unloading due to soil adhesion, the push plate relies only on linear thrust and cannot solve the problem of adhesion between the soil and the inner wall of the sampling tube; at the same time, the thrust is insufficient under complex soil conditions, and the push plate thrust depends on the lifting power of the threaded rod. If the soil sample is compact or contains stones, the push plate may get stuck, causing motor overload or mechanical damage.

[0005] Therefore, it is urgent to improve the above-mentioned sampling equipment to solve the above-mentioned problems. Summary of the Invention

[0006] The purpose of the present invention is to provide an energy-saving mining machinery and equipment with high unloading efficiency. In the unloading structure, the push rod and the abutment plate are designed to cooperate so that the scraping action is triggered synchronously with the lifting process of the sampling tube. No additional power source is required, which reduces energy consumption. The first reset spring provides elastic buffering to avoid damage to the equipment by rigid impact, while ensuring that the push rod is quickly reset, ensuring the stability of the scraper sleeve in the non-working state, and extending the service life of the scraper sleeve. The scraper sleeve removes adhered materials by shearing and peeling, which is particularly effective for high-humidity and high-viscosity ores. Compared with traditional static scrapers, dynamic scraping can reduce the amount of material residue and avoid unloading blockage.

[0007] The hollow top block and the first spray hole form a "scraping and flushing" composite cleaning system. After the scraper sleeve peels off the material, the infusion tube delivers high-pressure water or gas to the spray hole through the internal channel of the top block, which performs a secondary flushing on the scraped inner wall to thoroughly remove residual particles and ensure that the discharge channel is completely unobstructed.

[0008] The reciprocating motion driven by the chute, the adjustable striking force design, and the passive drive mechanism enable efficient vibration discharge of the material at the sampling barrel outlet. The chute consists of a linear groove and a wave groove. The wave groove converts the lifting motion into reciprocating motion through a wavy trajectory, eliminating the need for an additional power source and achieving efficient energy conversion. The striking frequency is determined by the lifting speed of the connecting sleeve and the wave period of the chute, ensuring that the striking action is synchronized with the sampling barrel's discharge process, maximizing discharge efficiency. Its innovative chute structure and modular design not only improve discharge efficiency, but also reduce energy consumption and maintenance costs. It is particularly suitable for mining scenarios with highly viscous and high-humidity materials.

[0025] The present invention has at least the following beneficial effects:

[0026] 1. When the connecting sleeve of the present invention is displaced, the reciprocating plate in the connecting part moves under the limit of the limit plate, and the roller thereon rolls in the slide groove inside the connecting sleeve. Since the slide groove is composed of a straight groove and a wave groove, as the connecting sleeve is displaced, the roller enters the wave groove from the straight groove. When the roller rolls in the wave groove, it drives the reciprocating plate to perform reciprocating motion. The reciprocating plate drives the mounting seat and the knocking block in the vibrating part to perform reciprocating motion through the connecting arm. The knocking block knocks the sampling cylinder, causing the material in the sampling cylinder to fall.

[0027] 2. The driving mechanism of the present invention realizes the rotation and lifting of the sampling cylinder, thereby improving the sampling efficiency. By utilizing the cooperation between the unloading structure 1 and the unloading structure 2, the material in the sampling cylinder is effectively caused to fall by scraping, vibrating, etc., thereby improving the unloading efficiency. At the same time, the infusion part realizes automatic lubrication of the roller and the slide groove, reducing equipment wear and extending the service life of the equipment.

[0028] 3. The present invention can adjust the distance between the knocking block and the sampling barrel by rotating the adjusting screw sleeve, which can adapt to the discharge requirements of different materials and improve the versatility of the equipment. In addition, the various components are tightly connected and the design is ingenious. The slide groove is composed of a straight groove and a wave groove, which realizes the reciprocating motion of the reciprocating plate and causes the material in the sampling barrel to fall.

[0029] 4. The present invention performs infusion through a reserved infusion tube. The liquid can also enter the top block through the infusion tube and then be sprayed out through the first spray hole to assist in material discharge. When in use, the scraper sleeve directly acts on the inner wall of the sampling tube. When the top block is pressed and moves, the scraper sleeve removes adhered materials in a shear-peeling manner, which is particularly effective for high-humidity and high-viscosity ores. Compared with traditional static scrapers, dynamic scraping can reduce the amount of material residue and avoid material discharge blockage. The hollow top block and the first spray hole form a "scraping and flushing" composite cleaning system. After the scraper sleeve strips the material, the infusion tube transports high-pressure water or gas to the spray hole through the internal channel of the top block, and performs a second flushing on the scraped inner wall to thoroughly remove residual particles and ensure that the material discharge channel is completely unobstructed.

[0030] 5. The lubricating part of the present invention is driven by the reciprocating motion of the connecting part, and does not require an additional power source. It shares the same energy source with the vibration unloading mechanism of the unloading structure 2, achieving dual effects in one machine and reducing the overall energy consumption of the equipment. The lubricating fluid forms an oil film between the roller and the slide groove, which reduces the friction coefficient, reduces the reciprocating motion resistance of the connecting part, reduces the driving energy consumption, and the lubricating fluid reduces the direct contact between the roller and the slide groove, avoids metal fatigue and wear, and extends the service life of the roller and the slide groove.

DETAILED DESCRIPTION

[0043] The technical solution of the present invention will be further described in detail below in conjunction with specific implementation methods.

[0044] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0045] like Figures 1-10 As shown, the energy-saving mining machinery provided in this embodiment includes a machine base 1, an L-shaped mounting frame 2 fixed to the outer wall of the machine base 1, and a sampling tube 3 arranged outside the L-shaped mounting frame 2. The L-shaped mounting frame 2 is provided with a drive mechanism 4 for driving the sampling tube 3. The drive mechanism 4 includes a drive motor 401 fixed to the interior of the L-shaped mounting frame 2. The internal bearing of the L-shaped mounting frame 2 is mounted with a transmission sleeve 402. The drive motor 401 is a dual-shaft motor with a dual-shaft design. One output shaft drives the transmission sleeve 402 to rotate through a gear member 403, thereby achieving rotation of the sampling tube 3; the other output shaft drives the sampling tube 3 to rise and fall through a screw 404 and a connecting plate 405. This design integrates the rotation and lifting functions into a single motor, reducing the size of the equipment and the number of transmission components, and improving the compactness of the structure. A meshing gear member 403 is provided between the outer surface of the transmission sleeve 402 and one of the output shafts of the drive motor 401. Specifically, the sampling tube 3 is spline-connected to the transmission sleeve 402, and the sampling tube 3 passes through the interior of the transmission sleeve 402. A screw 404 is fixed on the other output shaft of the driving motor 401, and the external thread of the screw 404 is connected to the connecting plate 405. A limit platform 406 connected to the end of the screw 404 is fixed on the outer wall of the L-shaped mounting frame 2.

[0046] To improve material removal efficiency, the L-shaped mounting frame 2 is externally provided with a material removal structure 1 5 and a material removal structure 2 6 , which work in conjunction with the material removal structure 1 5 . Material removal structure 1 5 includes a connecting sleeve 501 , within which is disposed a push rod 502 extending outward. A push block 503 is fixed to one end of the push rod 502 , which abuts against the inner wall of the connecting sleeve 501 . A reset member is provided between the push rod 502 and the connecting sleeve 501 . Specifically, one end of the connecting sleeve 501 is rotatably connected to the end of the sampling barrel 3 , and the threaded connection between the lead screw 404 and the connecting plate 405 converts the motor's rotational motion into linear motion of the sampling barrel 3 . The lead screw 404 transmission system features high transmission precision and accurate positioning, ensuring precise control of the lifting position of the sampling barrel 3 and improving sampling accuracy and efficiency. A connecting plate 405 is mounted on the outer surface of the connecting sleeve 501. A guide block 408 is fixed to the side of the connecting plate 405 facing away from the connecting sleeve 501. A guide groove 407 is provided within the L-shaped mounting bracket 2, which mates with the guide block 408. The connecting sleeve 501 is hollow, with both ends extending through it. The reset element comprises a circular ring 504 fixed to the outer surface of the ejector pin 502. A first reset spring 505, encircling the outer surface of the ejector pin 502, is secured between the outer wall of the circular ring 504 and the end of the connecting sleeve 501. The mating design of the ejector pin 502 and the abutment plate synchronizes the scraping action with the raising and lowering of the sampling tube 3. When the sampling tube 3 rises to the abutment plate position, the push rod 502 is pressed and moved, and the scraper sleeve 506 starts automatically without the need for an additional power source, reducing energy consumption. The first return spring 505 provides elastic buffering to avoid damage to the equipment caused by rigid impact, while ensuring that the push rod 502 is quickly reset when there is no external force, thereby ensuring the stability of the scraper sleeve 506 in the non-working state and extending the service life of the scraper sleeve 506.

[0047] It should be noted that a scraper sleeve 506 is fixed to the outer surface of the ejector block 503, and a liquid infusion tube 507 is fixed to the end of the ejector rod 502 away from the ejector block 503. The interior of the ejector block 503 is hollow and has a first spray hole 508 connected to the outside. The sampling device is provided with an abutment plate (not shown) that abuts against the ejector rod 502. During the movement of the sampling tube 3, the connecting plate 405 drives the connecting sleeve 501 to move. When the ejector block 503 at one end of the ejector rod 502 contacts the material, the lifting of the sampling tube 3 drives the ejector rod 502 to move synchronously. As the ejector rod 502 rises, it abuts against the abutment block provided in the device. Based on the lifting thrust, the ejector block 503 is compressed and drives the ejector rod 502 into the interior of the connecting sleeve 501. The circular ring 504 on the ejector rod 502 compresses the first return spring 505. At this time, the scraper sleeve 506 on the ejector block 503 can scrape the material on the inner wall of the sampling tube 3, assisting in material discharge. The infusion tube 507 can be connected to water, compressed air or chemical cleaning agents to adapt to different scenarios: wet cleaning: high-pressure water flushes sticky materials; dry cleaning: compressed air blows away dust; anti-caking treatment: injects antifreeze or dispersant to solve the problem of material compaction in low-temperature environments; and the distribution density and angle of the first spray hole 508 can be customized to enhance cleaning of areas of the sampling tube 3 where materials are prone to accumulation, such as ends and welds.

[0048] In addition, the reciprocating motion of the push rod 502 can be used to connect with the piston infusion structure. The reciprocating motion of the push rod 502 is coordinated with the reciprocating motion of the piston to achieve the pumping and infusion work, and then the infusion work is carried out through the reserved infusion tube 507. The liquid can also enter the top block 503 through the infusion tube 507 and then be sprayed out through the first spray hole 508 to assist in material discharge. When used in this application, the scraper sleeve 506 directly acts on the inner wall of the sampling tube 3. When the top block 503 is pressed and moved, the scraper sleeve 506 removes the adhered material in a shear-peeling manner, which is particularly effective for high-humidity, high-viscosity ores such as coal slime and clay. Compared with traditional static scrapers, dynamic scraping can reduce the amount of material residue by more than 60%, avoiding blockage in material discharge. The hollow top block 503 and the first spray hole 508 form a "scraping and flushing" composite cleaning system. After the scraping sleeve 506 peels off the material, the infusion tube 507 delivers high-pressure water flow / gas to the first spray hole 508 through the internal channel of the top block 503, flushing the scraped inner wall for the second time to completely remove residual particles and ensure that the discharge channel is completely unobstructed.

[0049] The second blanking structure 6 includes a connecting part 601 arranged on the outside of the connecting sleeve 501 and a vibrating part 602 arranged on the outside of the sampling tube 3; the connecting part 601 includes a reciprocating plate 6011, and a connecting shaft 6012 extending to the outside is fixed inside the reciprocating plate 6011, and a roller 6013 is rotatably installed on one end of the connecting shaft 6012, and a slide groove 605 used in conjunction with the roller 6013 is opened inside the connecting sleeve 501; it should be noted that the slide groove 605 is composed of a straight groove 6051 and a wave groove 6052. The vibrating member 602 includes a mounting base 6021 and a striking block 6022, with a groove 6023 formed on one side of the striking block 6022. Specifically, the groove 6023 is arc-shaped, with a protective pad 6024 fixed to the inner side of the groove 6023. An adjusting screw sleeve 6025 is rotatably mounted on the side of the mounting base 6021 away from the striking block 6022. An adjusting screw 6026 is fixed to the outer wall of the striking block 6022, passing through the mounting base 6021 and threadedly connected to the adjusting screw sleeve 6025. The threaded connection design of the adjusting screw sleeve 6025 and the adjusting screw 6026 allows the user to adjust the contact gap between the striking block 6022 and the sampling tube 3 by rotating the adjusting screw sleeve 6025, thereby controlling the striking force. The protective pad 6024 is made of an elastic material such as rubber, which acts as a buffer during the striking process, reducing mechanical damage to the sampling tube 3 and extending the service life of the striking block 6022. The knocking frequency is determined by the lifting speed of the connecting sleeve 501 and the wave period of the chute 605, ensuring that the knocking action is synchronized with the unloading process of the sampling tube 3 to maximize the unloading efficiency.

[0050] A stop plate 604 is fixed to the outer surface of the L-shaped mounting bracket 2, which limits the position of the reciprocating plate 6011. A connecting arm 6015, secured to one end of the reciprocating plate 6011 and secured to the mounting base 6021, is attached to the stop plate 604. A stop structure for limiting the position of the reciprocating plate 6011 is provided within the stop plate 604. The stop structure includes a slider 607. A stop slot 606 is defined within the reciprocating plate 6011. The slider 607 is secured to the inner side of the stop plate 604 and slidably connected to the stop slot 606. A stop rod 608 is secured between the inner walls of the opposite side of the stop slot 606 and extends through the slider 607. A second return spring 609 is secured between one side of the slider 607 and the stop slot 606. The reciprocating plate 6011 is connected to the roller 6013 via a connecting shaft 6012, which is embedded in the slide slot 605 of the connecting sleeve 501. The slide groove consists of a straight groove 6051 and a wave groove 6052. It should be noted that the straight groove 6051 ensures that the roller 6013 runs smoothly in the non-working state, reducing energy loss, while the wave groove 6052 converts the lifting motion into reciprocating motion through a wavy trajectory, without the need for an additional power source, thereby achieving efficient energy conversion.

[0051] When the connecting sleeve 501 rises and falls with the sampling tube 3, the roller 6013 generates a periodic undulating motion in the wave groove 6052, thereby driving the reciprocating plate 6011 to perform reciprocating linear motion. The reciprocating motion of the reciprocating plate 6011 is transmitted to the vibrating member 602 through the connecting member 601, causing the knocking block 6022 to generate high-frequency vibrations, breaking the "bridging" phenomenon of the material at the outlet of the sampling tube 3 and promoting the falling of the material. It should be noted that the unloading structure 2 6 realizes efficient vibration unloading of the material at the outlet of the sampling tube 3 through the chute-driven reciprocating motion, adjustable knocking force design and passive drive mechanism. Its innovative chute structure and modular design not only improve the unloading efficiency, but also reduce energy consumption and maintenance costs. It is particularly suitable for mining scenarios with high-viscosity and high-humidity materials, and is an important technical means for energy saving and efficiency improvement of mining machinery.

[0052] To ensure a stable connection between the roller 6013 and the chute 605, the connector 601 is externally provided with a lubricating infusion element 603. This infusion element 603 comprises a piston cylinder 6031 secured to the outer wall of the stop plate 604. A connecting seat 6035 is secured to the outer wall of the connecting arm 6015. A connecting rod 6036 is provided on one side of the connecting seat 6035, extending into the interior of the piston cylinder 6031. Two check valves 6032 are secured to the outer surface of the piston cylinder 6031. A first connecting tube 6033 and a second connecting tube 6034 are secured to the ends of the two check valves 6032. The second connecting tube 6034 is a flexible tube, accommodating the reciprocating motion of the connector 601 and preventing interference with rigid piping. The connecting shaft 6012 is hollow, and the roller 6013 is connected to the connecting shaft 6012. A second spray hole 6014 is also defined within the roller 6013. The connecting rod 6036 reciprocates within the piston cylinder 6031 as the connecting member 601 reciprocates, creating a hydraulic cycle of positive pressure discharge and negative pressure suction. When the connecting member 601 moves rightward, the connecting rod 6036 squeezes the liquid within the piston cylinder 6031, drawing liquid from the reservoir 7 through the first check valve 6032 and the first connecting tube 6033. When the connecting member 601 moves leftward, the liquid is forced into the connecting shaft 6012 through the second check valve 6032 and the second connecting tube 6034, achieving unidirectional flow of lubricant. The hollow connecting shaft 6012 delivers the lubricant to the interior of the roller 6013 and then sprays it directly onto the surface of the chute 605 through the second spray hole 6014, achieving "precision lubrication of the contact surface." The lubricant forms an oil film between the wavy contact surface of the roller 6013 and the chute 605, reducing the coefficient of friction and minimizing wear and the risk of sticking of the roller 6013. A collecting trough may also be provided on the bottom side of the chute 605 , and a partition net may be detachably installed in the collecting trough to collect excess lubricating fluid.

[0053] A liquid reservoir 7 is fixed to the upper surface of the L-shaped mounting frame 2. A first connecting tube 6033 and a second connecting tube 6034 are fixedly connected to the liquid reservoir 7 and the connecting shaft 6012 at their respective ends. The lubrication system is driven entirely by the reciprocating motion of the connector 601, requiring no additional power source. This system shares the same energy source as the vibrating unloading mechanism of the unloading structure 2 6, achieving a "one-machine, two-effect" approach and reducing overall energy consumption. The circulation of lubricating fluid between the piston cylinder 6031 and the roller 6013 not only reduces frictional heat but also removes heat through the fluid flow, preventing softening or deformation of the chute 605 and roller 6013 due to high temperatures, thereby extending the life of key components.

[0054] like Figures 1-10 As shown, the principle of the energy-saving mining machinery provided in this embodiment is as follows: in the driving mechanism 4, the driving motor 401 is started, and the transmission sleeve 402 is driven to rotate through the gear member 403. Since the sampling tube 3 is spline-connected to the transmission sleeve 402, the sampling tube 3 rotates accordingly to perform the sampling operation. At the same time, another output shaft of the driving motor 401 drives the screw 404 to rotate. The rotation of the screw 404 causes the threaded connecting plate 405 to move along the guide groove 407, thereby driving the connecting sleeve 501 and the sampling tube 3 to move, thereby realizing the lifting and lowering of the sampling tube 3 for sampling;

[0055] During the movement of the sampling cylinder 3, the connecting plate 405 drives the connecting sleeve 501 to move. When the top block 503 at one end of the push rod 502 contacts the material, the lifting and lowering of the sampling cylinder 3 drives the push rod 502 to move synchronously. When the push rod 502 rises, it fits into the abutment block provided in the equipment and, based on the lifting and lowering reasoning, the top block 503 is pressed to drive the push rod 502 to move toward the inside of the connecting sleeve 501. The circular ring 504 on the push rod 502 compresses the first return spring 505. At this time, the scraping sleeve 506 on the top block 503 can scrape the material on the inner wall of the sampling cylinder 3 to assist in material unloading.

[0056] When the connecting sleeve 501 is displaced, the reciprocating plate 6011 in the connecting member 601 moves under the limit of the limit plate 604, and the roller 6013 thereon rolls in the chute 605 inside the connecting sleeve 501. Since the chute 605 is composed of a straight groove 6051 and a wave groove 6052, as the connecting sleeve 501 is displaced, the roller 6013 enters the wave groove 6052 from the straight groove 6051. When the roller 6013 rolls in the wave groove 6052, it drives the reciprocating plate 6011 to reciprocate. The reciprocating plate 6011 drives the mounting seat 6021 and the knocking block 6022 in the vibrating member 602 to reciprocate through the connecting arm 6015. The knocking block 6022 knocks the sampling tube 3, causing the material in the sampling tube 3 to fall.

[0057] When the reciprocating plate 6011 reciprocates, it drives the connecting seat 6035 and the connecting rod 6036 to reciprocate in the piston cylinder 6031. When the connecting rod 6036 moves into the piston cylinder 6031, a check valve 6032 opens, and the liquid in the liquid storage tank 7 enters the piston cylinder 6031 through the first connecting pipe 6033. When the connecting rod 6036 moves outward, the other check valve 6032 opens, and the liquid in the piston cylinder 6031 enters the connecting shaft 6012 through the second connecting pipe 6034, and is then sprayed out through the second spray hole 6014 on the roller 6013 to lubricate the roller 6013 and the chute 605. At the same time, the liquid can also enter the top block 503 through the liquid infusion pipe 507 and be sprayed out through the first spray hole 508 to assist in unloading.

[0058] In addition, by rotating the adjusting screw sleeve 6025, the adjusting screw 6026 can drive the knocking block 6022 to move, and the distance between the knocking block 6022 and the sampling tube 3 can be adjusted to meet different material discharge requirements.

[0059] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of the components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term and should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.
