[0025] The present application has at least the following advantages:

[0026] 1. When the connecting sleeve of the present invention is displaced, the reciprocating plate in the connecting member moves under the limitation of the limiting plate, and the roller on it rolls in the sliding groove inside the connecting sleeve. Since the sliding groove is composed of a straight groove and a wave groove, as the connecting sleeve is displaced, the roller enters from the straight groove into the wave groove. When the roller rolls in the wave groove, it will drive the reciprocating plate to reciprocate. The reciprocating plate drives the mounting seat and the striking block in the vibrating member to reciprocate through the connecting arm. The striking block strikes the sampling cylinder, causing the material in the sampling cylinder to fall.

[0027] 2. The driving mechanism of this invention realizes the rotation and lifting of the sampling cylinder, which improves the sampling efficiency. By utilizing the cooperation of feeding structure one and feeding structure two, the material in the sampling cylinder is effectively promoted to fall through scraping, vibration and other means, which improves the feeding efficiency. At the same time, the infusion component realizes the automatic lubrication of the roller and the chute, which reduces equipment wear and extends the service life of the equipment.

[0028] 3. This invention allows for adjustment of the distance between the striking block and the sampling cylinder by rotating the adjusting screw sleeve, adapting to the feeding requirements of different materials, improving the versatility of the equipment. Furthermore, the components are tightly connected and cleverly designed. The slide groove, composed of straight grooves and wave grooves, enables the reciprocating motion of the reciprocating plate, causing the material in the sampling cylinder to fall.

[0029] 4. This invention uses a pre-installed infusion pipe for liquid delivery. Liquid can also enter the top block through the infusion pipe and then be sprayed out through the first spray hole to assist in material feeding. During use, the scraper sleeve acts directly on the inner wall of the sampling cylinder. When the top block is pressed and moves, the scraper sleeve removes the adhering material by shearing and peeling. It 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 blockage. 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 pipe delivers high-pressure water or gas to the spray hole through the internal channel of the top block to perform a secondary flushing of the scraped inner wall, thoroughly removing residual particles and ensuring that the material feeding channel is completely unobstructed.

[0030] 5. The lubricating component of this invention is driven by the reciprocating motion of the connecting component, without the need for an additional power source. It shares the same energy source with the vibration feeding mechanism of the second feeding structure, achieving dual effects in one machine and reducing the overall energy consumption of the equipment. The lubricant forms an oil film between the roller and the slide, which reduces the coefficient of friction, reduces the resistance of the reciprocating motion of the connecting component, and reduces the driving energy consumption. In addition, the lubricant reduces the direct contact between the roller and the slide, avoids metal fatigue and wear, and extends the service life of the roller and the slide.

Detailed Implementation

[0043] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

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

[0045] like Figures 1-10 As shown, the energy-saving mining machinery equipment provided in this embodiment includes a base 1, an L-shaped mounting frame 2 fixed to the outer wall of the base 1, and a sampling cylinder 3 disposed outside the L-shaped mounting frame 2. A drive mechanism 4 for driving the sampling cylinder 3 is provided on the L-shaped mounting frame 2. The drive mechanism 4 includes a drive motor 401 fixed inside the L-shaped mounting frame 2. A transmission sleeve 402 is mounted on the internal bearing of the L-shaped mounting frame 2. The drive motor 401 is a dual-shaft motor with a dual-shaft design. One output shaft drives the transmission sleeve 402 to rotate via a gear component 403, thereby rotating the sampling cylinder 3; the other output shaft drives the sampling cylinder 3 to lift and lower via a lead screw 404 and a connecting plate 405. This design integrates rotation and lifting functions into one motor, reducing the equipment size and the number of transmission components, and improving structural compactness. A meshing gear component 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 cylinder 3 is splinedly connected to the transmission sleeve 402, and the sampling cylinder 3 passes through the inside of the transmission sleeve 402. A lead screw 404 is fixed on another output shaft of the drive motor 401. A connecting plate 405 is threadedly connected to the outside of the lead screw 404. A limiting platform 406 connected to the end of the lead screw 404 is fixed on the outer wall of the L-shaped mounting bracket 2.

[0046] In order to improve the discharging efficiency, the L-shaped mounting frame 2 is externally provided with a first discharging structure 5 and a second discharging structure 6, and the second discharging structure 6 is used in cooperation with the first discharging structure 5; the first discharging structure 5 comprises a connecting sleeve 501, the inside of the connecting sleeve 501 is provided with a top rod 502 extending to the outside, one end of the top rod 502 is fixedly provided with a top block 503 abutting against the inner wall of the connecting sleeve 501, and a reset member is arranged between the top rod 502 and the connecting sleeve 501; specifically, one end of the connecting sleeve 501 is rotatably connected with the end portion of the sampling cylinder 3, the lead screw 404 is threadedly connected with the connecting plate 405, and the rotary motion of the motor is converted into the linear motion of the sampling cylinder 3. The lead screw 404 transmission has the characteristics of high transmission precision and accurate positioning, which ensures the accurate control of the lifting position of the sampling cylinder 3 and improves the sampling accuracy and efficiency. The connecting plate 405 is installed on the outer surface of the connecting sleeve 501, the side of the connecting plate 405 away from the connecting sleeve 501 is fixedly provided with a guide block 408, and the inside of the L-shaped mounting frame 2 is provided with a guide groove 407 matched with the guide block 408. The inside of the connecting sleeve 501 is hollow and the two ends are through, the reset member comprises a circular ring 504 fixed to the outer surface of the top rod 502, and the outer wall of the circular ring 504 and the end portion of the connecting sleeve 501 are fixedly provided with a first reset spring 505 surrounding the outside of the top rod 502. The cooperation design of the top rod 502 and the abutting plate makes the scraping action and the lifting process of the sampling cylinder 3 synchronous triggering. When the sampling cylinder 3 rises to the position of the abutting plate, the top rod 502 is pressed to move, the scraping sleeve 506 is automatically started, no additional power source is needed, the energy consumption is reduced, the first reset spring 505 provides elastic buffer, avoids the damage to the equipment caused by rigid impact, at the same time ensures the rapid reset of the top rod 502 without external force, guarantees the stability of the scraping sleeve 506 in the non-working state, prolongs the service life of the scraping sleeve 506.

[0047] It should be noted that the outer surface of the top block 503 is fixed with a scraping sleeve 506, the end of the top rod 502 away from the top block 503 is fixed with a liquid delivery pipe 507, the inside of the top block 503 is hollow, and a first spray hole 508 is arranged in the inside of the top block 503 and communicates with the outside. An abutting plate (not shown in the figure) is arranged on the sampling device and abuts against the top rod 502. 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 top rod 502 contacts the material, the top rod 502 moves synchronously due to the lifting of the sampling cylinder 3. When the top rod 502 rises, it is attached to the abutting block arranged in the device and is pressed to drive the top rod 502 to move into the connecting sleeve 501 according to the lifting thrust. The circular ring 504 on the top 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 discharging. The liquid delivery pipe 507 can be connected to water, compressed air or chemical cleaning agent to adapt to different scenes: wet cleaning: high-pressure water flushing of sticky material; dry cleaning: compressed air blowing dust; anti-caking treatment: injection of antifreeze or dispersant to solve the problem of material hardening in low temperature environment; and the distribution density and angle of the first spray hole 508 can be customized for enhanced cleaning of the areas prone to material accumulation of the sampling cylinder 3, such as the end and the weld.

[0048] In addition, the reciprocating motion of the top rod 502 can also be connected with the piston liquid delivery structure. Through the reciprocating cooperation of the top rod 502 and the piston, the liquid pumping and delivery work can be realized, and then the liquid delivery work can be carried out through the reserved liquid delivery pipe 507. The liquid can also enter the top block 503 through the liquid delivery pipe 507 and then be sprayed out through the first spray hole 508 to assist in discharging. When the scraping sleeve 506 is used, it directly acts on the inner wall of the sampling cylinder 3. When the top block 503 is pressed to move, the scraping sleeve 506 removes the adhered material in a shearing and peeling manner, especially for high-humidity and high-viscosity ores such as coal slime and clay. Compared with the traditional static scraping plate, the dynamic scraping can reduce the residual amount of material by more than 60%, avoiding the blockage of discharging. The hollow top block 503 and the first spray hole 508 form a "scraping and flushing" composite cleaning system. After the material is peeled off by the scraping sleeve 506, the liquid delivery pipe 507 delivers high-pressure water flow / gas to the first spray hole 508 through the internal passage of the top block 503 to flush the inner wall again, completely removing the residual particles and ensuring that the discharging channel is completely unblocked.

[0049] The blanking structure two 6 includes a connecting piece 601 arranged outside the connecting sleeve 501 and a vibrating piece 602 arranged outside the sampling cylinder 3; the connecting piece 601 includes a reciprocating plate 6011, the inside of the reciprocating plate 6011 is fixed with a connecting shaft 6012 extending to the outside, one end of the connecting shaft 6012 is rotatably installed with a roller 6013, and the inside of the connecting sleeve 501 is provided with a sliding groove 605 matched with the roller 6013; it should be noted that the sliding groove 605 is composed of a straight groove 6051 and a wave groove 6052. The vibrating piece 602 includes a mounting seat 6021 and a knocking block 6022, one side of the knocking block 6022 is provided with a groove 6023; specifically, the shape of the groove 6023 is arc-shaped, the inner side of the groove 6023 is fixed with a protective pad 6024, the side of the mounting seat 6021 away from the knocking block 6022 is rotatably installed with an adjusting sleeve 6025, and the outer wall of the knocking block 6022 is fixed with an adjusting screw 6026 penetrating through the mounting seat 6021 and threadedly connected with the adjusting sleeve 6025. The threaded connection design of the adjusting sleeve 6025 and the adjusting screw 6026 allows the user to adjust the contact gap between the knocking block 6022 and the sampling cylinder 3 by rotating the adjusting sleeve 6025, so as to control the knocking force. The protective pad 6024 is made of elastic material such as rubber, which plays a buffering role during knocking, reduces mechanical damage to the sampling cylinder 3, and prolongs the service life of the knocking block 6022. The knocking frequency is determined by the lifting speed of the connecting sleeve 501 and the wave period of the sliding groove 605, which ensures that the knocking action is synchronized with the blanking process of the sampling cylinder 3, and maximizes the blanking efficiency.

[0050] The outer surface of the L-shaped mounting bracket 2 is fixed with a limiting plate 604 limiting the reciprocating plate 6011, one end of the reciprocating plate 6011 is fixed with a connecting arm 6015 fixed with the mounting seat 6021, wherein the inside of the limiting plate 604 is provided with a limiting structure limiting the reciprocating plate 6011, the inside of the reciprocating plate 6011 is provided with a limiting groove 606, the sliding block 607 is fixed to the inside of the limiting plate 604 and is in sliding connection with the limiting groove 606, the limiting rods 608 penetrating through the inside of the sliding block 607 are fixed between the inner walls of the opposite sides of the limiting groove 606, and the second return spring 609 is fixed between one side of the sliding block 607 and the limiting groove 606. The reciprocating plate 6011 is connected with the roller 6013 through the connecting shaft 6012 and is embedded in the sliding groove 605 of the connecting sleeve 501. The sliding groove is composed of the straight groove 6051 and the wave groove 6052, and it should be noted that the straight groove 6051 ensures smooth running of the roller 6013 in the non-working state, reducing energy loss, and the wave groove 6052 converts the lifting motion into reciprocating motion through the wave-shaped track, without the need for an additional power source, realizing efficient energy conversion.

[0051] When the connecting sleeve 501 is lifted with the sampling cylinder 3, the roller 6013 produces periodic undulating motion in the wave groove 6052, which in turn drives the reciprocating plate 6011 to produce reciprocating linear motion. The reciprocating motion of the reciprocating plate 6011 is transmitted to the vibrating member 602 through the connecting member 601, so that the knocking block 6022 produces high-frequency vibration, breaks the "bridge" phenomenon of the material at the outlet of the sampling cylinder 3, and promotes the falling of the material. It should be noted that the second discharging structure 6 realizes efficient vibration discharging of the material at the outlet of the sampling cylinder 3 through the slide groove driven reciprocating motion, adjustable knocking force and passive driving mechanism. The innovative slide groove structure and modular design not only improve the discharging efficiency, but also reduce the energy consumption and maintenance cost, especially suitable for high-viscosity and high-humidity material mining scenes, which is an important technical means for energy saving and efficiency improvement of mining machinery.

[0052] To ensure the stable connection of the roller 6013 and the slide groove 605, the connecting member 601 is externally provided with a liquid delivery member 603 for lubrication. The liquid delivery member 603 includes a piston cylinder 6031 fixed to the outer wall of the limiting plate 604. The outer wall of the connecting arm 6015 is fixed with a connecting seat 6035. The connecting seat 6035 is provided with a connecting rod 6036 extending into the interior of the piston cylinder 6031. The outer surface of the piston cylinder 6031 is fixed with two check valves 6032. The two check valves 6032 are respectively fixed with a first connecting pipe 6033 and a second connecting pipe 6034 at the opposite ends. The second connecting pipe 6034 is a flexible pipe. The reciprocating motion of the connecting member 601 is adapted to avoid the interference of the rigid pipe. The connecting shaft 6012 is a hollow shaft. The interior of the roller 6013 is communicated with the connecting shaft 6012. The interior of the roller 6013 is provided with a second spray hole 6014. The connecting rod 6036 reciprocates in the piston cylinder 6031 with the reciprocating motion of the connecting member 601, forming a hydraulic cycle of positive pressure liquid discharge and negative pressure liquid suction. When the connecting member 601 moves to the right, the connecting rod 6036 extrudes the liquid in the piston cylinder 6031, and the liquid is sucked from the liquid storage tank 7 through the first check valve 6032 and the first connecting pipe 6033. When the connecting member 601 moves to the left, the liquid is pressed into the connecting shaft 6012 through the second check valve 6032 and the second connecting pipe 6034, realizing the one-way flow of the lubricating liquid. The hollow connecting shaft 6012 delivers the lubricating liquid to the interior of the roller 6013, and sprays it directly to the surface of the slide groove 605 through the second spray hole 6014, forming "precise lubrication of the contact surface". The lubricating liquid forms an oil film between the wave-shaped contact surface of the roller 6013 and the slide groove 605, reducing the friction coefficient and reducing the risk of wear and jamming of the roller 6013. The bottom side of the slide groove 605 can also be provided with a collection groove. The collection groove is detachably installed with a screen, so as to collect the excess lubricating liquid.

[0053] The upper surface of the L-shaped mounting frame 2 is fixed with a liquid storage tank 7, and the first connecting pipe 6033 and the second connecting pipe 6034 are fixedly communicated with the liquid storage tank 7 and the connecting shaft 6012 respectively at one end. The lubricating system is completely driven by the reciprocating movement of the connecting piece 601, and does not need an additional power source, and shares the same energy source with the vibration blanking mechanism of the second blanking structure 6, realizes "one machine with double effects", reduces the overall energy consumption of the equipment, and the circulation of the lubricating liquid between the piston cylinder 6031 and the roller 6013 not only reduces the friction heat, but also takes away the heat through the liquid flow, prevents the chute 605 and the roller 6013 from softening or deforming due to high temperature, and prolongs the service life of the key components.

[0054] As shown in Figures 1-10 The principle of the energy-saving mine mechanical equipment provided by the embodiment is as follows: in the driving mechanism 4, the driving motor 401 is started, the transmission sleeve 402 is driven to rotate through the gear piece 403, the sampling cylinder 3 is connected with the transmission sleeve 402 by means of spline, so the sampling cylinder 3 rotates to perform sampling operation, at the same time, the other output shaft of the driving motor 401 drives the lead screw 404 to rotate, the lead screw 404 rotates to drive the connecting plate 405 connected by threads to move along the direction of the guide groove 407, and then drives the connecting sleeve 501 and the sampling cylinder 3 to move, so as to realize the lifting sampling of the sampling cylinder 3;

[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 jacking rod 502 contacts with the material, since the sampling cylinder 3 drives the jacking rod 502 to move synchronously, when the jacking rod 502 rises, the jacking rod 502 is in contact with the abutting block arranged in the equipment and moves according to the lifting theory, so that the top block 503 is pressed to drive the jacking rod 502 to move to the inside of the connecting sleeve 501, and the circular ring 504 on the jacking rod 502 compresses the first reset 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, and assist in blanking;

[0056] When the connecting sleeve 501 moves, the reciprocating plate 6011 in the connecting piece 601 moves under the limitation of the limiting plate 604, and the roller 6013 on the reciprocating plate 6011 rolls in the chute 605 in the connecting sleeve 501, since the chute 605 is composed of the straight groove 6051 and the wave groove 6052, with the displacement of the connecting sleeve 501, the roller 6013 enters from the straight groove 6051 into the wave groove 6052, when the roller 6013 rolls in the wave groove 6052, it drives the reciprocating plate 6011 to do reciprocating motion, the reciprocating plate 6011 drives the mounting seat 6021 and the knocking block 6022 in the vibrating piece 602 to do reciprocating motion through the connecting arm 6015, the knocking block 6022 knocks the sampling cylinder 3, and promotes the material in the sampling cylinder 3 to fall;

[0057] When the reciprocating plate 6011 reciprocates, the connecting seat 6035 and the connecting rod 6036 reciprocate in the piston cylinder 6031. When the connecting rod 6036 moves into the piston cylinder 6031, one 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 outwards, 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 sprayed out through the second spray hole 6014 on the roller 6013, lubricating the roller 6013 and the chute 605. At the same time, the liquid can also enter the top block 503 through the liquid delivery pipe 507, and be sprayed out through the first spray hole 508, assisting in discharging;

[0058] In addition, by rotating the adjusting 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 cylinder 3 can be adjusted to adapt to different discharging requirements.
