Description

Technical Field

[0001] This utility model belongs to the field of coal mine production technology, and more specifically, it relates to an automated coal conveying anti-blocking device. Background Technology

[0002] Coal transportation refers to the entire process of transferring coal from the mining site to the end user through a series of equipment and systems. It is a key link in the coal industry chain, connecting production, processing, transportation, and consumption, and directly affects the efficiency and cost of coal supply. Currently, in the vertical coal transportation process, coal conveyor belts typically feed coal blocks into coal drop hoppers, causing the coal blocks to fall along the hoppers to the corresponding loading area. Because traditional coal drop hoppers have a constricted bottom structure, excessive speed and volume during loading can cause the coal in the hopper to accumulate and compact instantly at the constricted bottom, leading to blockage at the coal outlet. In this case, the entire coal transportation system must be shut down first, and then coal loading and unloading workers must clear the blockage at the coal outlet. It is evident that the clearing and cleaning work at the coal drop hopper outlet significantly reduces coal transportation efficiency and disrupts the continuity of automated coal transportation. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides an automated coal conveying anti-blockage device for coal mines, which solves the problem that the unblocking and cleaning work at the coal outlet of the coal hopper in traditional coal conveying operations reduces coal conveying efficiency and disrupts the continuity of automated coal conveying.

[0004] This utility model provides an automated coal conveying anti-blocking device for coal mines, including a ring plate frame; a coal hopper is welded to the inner side of the ring plate frame, a support is welded to the outer side of the coal hopper, and a control machine is installed on the inner side of the support; it also includes a top cover; a rotating drum is rotatably connected to the lower side of the top cover, a dredging motor is installed on the upper side of the top cover, a drive gear is installed on the motor shaft of the dredging motor, a through hole is provided at the center of the upper side of the top cover, a lifting column is slidably connected in the through hole of the top cover, a dredging rod is welded to the bottom end of the lifting column, a baffle is bolted to the lower side of the top cover, a coal hopper is bolted to the lower side of the baffle, a support shell is welded to the outer side of the coal hopper, a water pump is installed on the support shell, a water supply pipe is installed at the outlet of the water pump, and a water distribution pipe is installed at the other end of the water supply pipe.

[0005] Furthermore, the rotating drum is a cylindrical structure that runs vertically through the top and bottom. The inner side of the cylindrical structure of the rotating drum is provided with an annular arc-shaped groove, and the outer side of the rotating drum is provided with a ring plate near the bottom. The outer side of the ring plate of the rotating drum is surrounded by an external tooth structure. The external tooth structure of the drive gear is meshed with the external tooth structure of the rotating drum, and the unblocking motor drives the rotating drum to rotate through the drive gear.

[0006] Furthermore, a guide block is welded to the outer side of the lifting column near the bottom. The guide block is a cuboid protrusion structure. A pushing column is welded to the outer side of the lifting column near the center. The pushing column is a cylindrical column structure and is embedded in the annular arc-shaped groove on the inner side of the cylindrical structure of the rotating cylinder.

[0007] Furthermore, six sets of insert plates are welded to the outer side of the unblocking rod near the bottom end, and the insert plates are arranged in a ring array around the vertical central axis of the unblocking rod.

[0008] Furthermore, the upper side of the top cover is provided with a protruding post, and the center of the top of the protruding post is provided with a through hole structure that runs vertically through the top and bottom. The inner side of the through hole structure of the protruding post of the top cover is provided with two sets of long strip opening grooves, and the two sets of guide blocks welded to the outer side of the lifting post are respectively embedded in the long strip opening grooves of the top cover.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. In this utility model, the rotating drum, which is meshed with the outer side of the drive gear by the unblocking motor, rotates. The inner side of the rotating drum has an annular arc-shaped groove wall that pushes and presses the column, causing the lifting column to move up and down repeatedly. This allows the unblocking rod to repeatedly penetrate and unblock the coal blocks accumulated at the bottom of the coal hopper. Without stopping the conveying equipment, the blockage at the coal outlet of the coal hopper can be dealt with in a timely manner, preventing the coal blocks from standing still and compacting at the outlet. This greatly improves the efficiency of coal conveying and ensures the continuity of automated coal conveying.

[0012] 2. In this utility model, a water pump is used to transport water from an external water pipe to a distribution pipe via a delivery pipe. The distribution pipe then diverts the water to an atomizing nozzle, where it is sprayed as a water mist onto the bottom of the coal hopper. A water mist barrier is formed on the outside of the coal outlet at the bottom of the coal hopper. During the coal unloading process, the water mist barrier can effectively adsorb and settle coal ash, preventing coal ash from drifting outwards, reducing the diffusion pollution of coal ash in the air, improving the working environment for coal transportation, and reducing air pollution to the surrounding environment.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] like Figures 1-7 As shown, this utility model provides an automated coal conveying anti-blocking device for coal mines, including a ring plate frame 1; a coal hopper 10 is welded to the inner side of the ring plate frame 1, a support 19 is welded to the outer side of the coal hopper 10, and a control machine 18 is installed on the inner side of the support 19; it also includes a top cover 3; a rotating drum 14 is rotatably connected to the lower side of the top cover 3, a dredging motor 11 is installed on the upper side of the top cover 3, a drive gear 12 is installed on the motor shaft of the dredging motor 11, a through hole is provided at the center of the upper side of the top cover 3, a lifting column 5 is slidably connected in the through hole of the top cover 3, a dredging rod 9 is welded to the bottom end of the lifting column 5, a baffle 4 is bolted to the lower side of the top cover 3, a coal hopper 10 is bolted to the lower side of the baffle 4, a support shell 17 is welded to the outer side of the coal hopper 10, a water pump 15 is installed on the support shell 17, a water supply pipe 16 is installed at the outlet of the water pump 15, and a water distribution pipe 7 is installed at the other end of the water supply pipe 16.

[0023] In this embodiment of the utility model, the rotating drum 14 is a cylindrical structure that runs vertically through the top and bottom. The inner side of the cylindrical structure of the rotating drum 14 is provided with an annular arc-shaped groove, and the outer side of the rotating drum 14 is provided with a ring plate near the bottom. The outer side of the ring plate of the rotating drum 14 is surrounded by an external tooth structure. The external tooth structure of the drive gear 12 is meshed with the external tooth structure of the rotating drum 14. The unblocking motor 11 drives the rotating drum 14 to rotate through the drive gear 12. The gear meshing method formed by the drive gear 12 and the external tooth structure of the rotating drum 14 is not easy to slip. When dealing with hard blockages, it can provide a stable torque output to the rotating drum 14 and avoid the interruption of unblocking of the coal outlet of the coal hopper 10 by the unblocking rod 9 due to power transmission failure.

[0024] In this embodiment of the utility model, a guide block 6 is welded to the outer side of the lifting column 5 near the bottom. The guide block 6 is a cuboid protrusion structure. A pushing column 13 is welded to the outer side of the lifting column 5 near the center. The pushing column 13 is a cylindrical column structure. The pushing column 13 is embedded in the annular arc-shaped groove on the inner side of the cylindrical structure of the rotating cylinder 14. During the rotation of the rotating cylinder 14, the groove wall of the annular arc-shaped groove of the rotating cylinder 14 pushes the pushing column 13, causing the pushing column 13 to drive the lifting column 5 to move up and down repeatedly. This allows the lifting column 5 to push the unblocking rod 9 to repeatedly insert and unblock the coal blocks accumulated at the bottom coal outlet of the coal hopper 10. The coal blocks loosen during the insertion of the unblocking rod 9, preventing the coal blocks from being stationary and compacted at the coal outlet.

[0025] In this embodiment of the utility model, six sets of insert plates 2 are welded to the outer side of the unblocking rod 9 near the bottom. The insert plates 2 are arranged in a ring array around the vertical central axis of the unblocking rod 9. By using the six sets of insert plates 2, the unblocking rod 9 increases the unblocking contact area with the coal block, and contacts the coal block from multiple angles, quickly breaking the "arch bridge" structure or clumps formed by the coal, shortening the unblocking time, and improving the coal block unblocking efficiency.

[0026] In this embodiment of the utility model, the upper side of the top cover 3 is provided with a protruding post, and the center of the top of the protruding post is provided with a through hole structure that runs vertically through the top. The inner side of the through hole structure of the protruding post of the top cover 3 is provided with two sets of long strip opening grooves. The two sets of guide blocks 6 welded to the outer side of the lifting column 5 are respectively embedded in the long strip opening grooves of the top cover 3. The long strip opening grooves of the top cover 3 support the lifting column 5 to move vertically and stably up and down through the guide blocks 6, so as to avoid the inner side of the rotating drum 14 rotating and pushing the lifting column 5 welded to the pushing column 13 to rotate horizontally during the rotation of the rotating drum 14. This ensures that the lifting column 5 drives the unblocking rod 9 to repeatedly and stably move up and down through the coal outlet at the bottom of the coal hopper 10.

[0027] In this embodiment of the utility model, the water distribution pipe 7 has a circular pipe structure. The bottom of the circular pipe structure of the water distribution pipe 7 is provided with eighteen sets of water outlet pipes. Each set of water outlet pipes is equipped with an atomizing nozzle 8. The water pump 15 transports water from the external water pipe to the water distribution pipe 7 through the water supply pipe 16. The water distribution pipe 7 then diverts the water to the atomizing nozzles 8 installed at the ends of the eighteen sets of water outlet pipes and sprays it out to the bottom of the coal hopper 10 in the form of water mist. A water mist barrier is formed on the outside of the coal outlet at the bottom of the coal hopper 10 to prevent coal ash from drifting outward during the unloading process at the coal outlet at the bottom of the coal hopper 10, thereby reducing the diffusion pollution of coal ash in the air.

[0028] Specific usage and function of this utility model embodiment:

[0029] In this invention, during the vertical coal conveying process of the coal hopper 10, when clearing coal blocks at the coal outlet, the control unit 18 controls the start of the clearing motor 11 via a wire. The clearing motor 11 drives the drive gear 12 to rotate. Since the drive gear 12 is meshed with the outer tooth structure of the rotating drum 14, the drive gear 12 drives the rotating drum 14 to rotate on the lower side of the top cover 3. Because the pushing column 13, which is welded to the center of the outer side of the lifting column 5, is embedded in the annular arc-shaped groove on the inner side of the rotating drum 14, during the rotation of the rotating drum 14, the groove wall of the annular arc-shaped groove of the rotating drum 14 pushes against the pushing column 13. The pushing column 13 drives the lifting column 5 to move up and down along the long opening groove of the top cover 3. The lifting column 5 moves back and forth, driving the unblocking rod 9 welded to the bottom end to move synchronously up and down at the coal outlet of the bottom of the coal hopper 10. The insert plate 2 welded to the outer side of the unblocking rod 9 repeatedly moves up and down between the accumulated coal blocks, causing the static and compacted coal blocks to loosen, thus allowing the coal blocks to be discharged from the coal outlet of the coal hopper 10. During the discharge process, the water pump 15 transports water from the external water pipe to the water distribution pipe 7 through the water supply pipe 16. The water distribution pipe 7 then distributes the water to the atomizing nozzle 8, which sprays the water in a mist form to prevent coal ash from spreading and polluting the coal outlet of the coal hopper 10, thereby completing the coal block unblocking work at the coal outlet during the vertical coal conveying process of the coal hopper 10.

[0030] All the above components are installed, connected, or set up using common mechanical methods, such as welding, threaded connections, and screw connections. Furthermore, the specific structure, model, and coefficient indicators of all components are based on their own technologies. Any method that achieves the desired beneficial effect can be implemented. The atomizing nozzle 8, unblocking motor 11, water pump 15, and control unit 18 mentioned above are all common market components. Upon purchase and use, simply connect them according to the instruction manual provided with the purchase; therefore, further details are omitted here.
