Description

Technical Field

[0001] This invention relates to the technical field of feeding devices, and more particularly to a feeding device for coal mines. Background Technology

[0002] In coal mining operations, the mine feeding device is a key piece of equipment connecting the mining and transportation stages. It is mainly used to transport mined coal particles to the transport vehicle, and its operational stability and feeding uniformity directly affect the overall efficiency and safety of coal mining operations. Currently, most existing coal mine feeding devices use conveyor belts for feeding, and the material guiding structure is mostly fixed. Typically, the coal is transported to a designated height by a lifting conveyor belt and then dropped directly into the transport vehicle through fixed guide hoppers. The overall structure is relatively simple, relying mainly on the continuous operation of the lifting mechanism to achieve continuous feeding.

[0003] However, existing feeding devices have many shortcomings and are difficult to meet the actual operational needs of coal mines. The core problem is that the discharge port of the feeding device is fixed and cannot be moved. When conveying solid coal particles to the mine car bucket, the coal can only accumulate at a fixed point in the bucket, which cannot achieve uniform distribution. This leads to a shift in the center of gravity of the bucket, making the mine car less stable and posing a safety hazard. It also results in poor feeding effect and makes it difficult to make full use of the loading space in the bucket.

[0004] In addition, some feeding devices with simple swing functions have poor coordination between the material guiding structure and the swing mechanism. During the swing process, problems such as jamming and insufficient displacement compensation may occur, which not only leads to unstable material guiding and affects feeding efficiency, but may also cause coal to scatter and increase the workload of on-site cleaning.

[0046] To better explain and facilitate understanding of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0047] This embodiment provides a coal mine feeding device, such as... Figures 1 to 4As shown, the device includes a lifting mechanism 100, a guiding mechanism 200, and a swinging mechanism 300. The guiding mechanism 200 includes a rotating disk 210 rotatably mounted on the lifting mechanism 100. The top of the rotating disk 210 has an upward-opening collecting hopper 220 for receiving material falling from the lifting mechanism 100. The bottom of the collecting hopper 220 is connected to a guiding pipe 230. The swinging mechanism 300 includes a sliding collar 310 and an end frame 320. The sliding collar 310 is movably sleeved on the outside of the guiding pipe 230 and can slide along the guiding pipe 230. The sliding collar 310 is mounted on the end frame 320 via a lateral movement mechanism 330, which drives the sliding collar 310 to move laterally, causing the outlet of the guiding pipe 230 to swing laterally.

[0048] The lifting mechanism 100 is used to transport coal particles from the ground to a certain height, preparing them for subsequent loading. The guiding mechanism 200 receives the material from the lifting mechanism 100 and guides the coal particles to the loading truck through the guiding pipe 230. The swing mechanism 300 enables the discharge port at the end of the guiding pipe 230 to move laterally.

[0049] Specifically, the rotating disk 210, rotatably mounted on the lifting mechanism 100, can flexibly adjust the orientation of the collecting hopper 220, ensuring that the collecting hopper 220 accurately receives the material falling from the lifting mechanism 100, reducing spillage and improving the stability of material receiving. The upward-opening collecting hopper 220 expands the material receiving range, further reducing material loss, and facilitates the smooth entry of coal particles into the guiding pipe 230. The guiding pipe 230 can directionally transport the received coal particles. The sliding collar 310 is movably fitted on the outside of the guiding pipe 230 and can slide along the guiding pipe 230. This mechanism allows the lateral movement mechanism 330 to adaptively compensate for the displacement changes of the guiding pipe 230 when it drives the sliding collar 310 to move laterally, ensuring smooth and unobstructed movement of the guiding pipe 230.

[0050] Therefore, the lateral movement mechanism 330 works in coordination with the sliding collar 310 and the end frame 320 to stably drive the sliding collar 310 to move laterally, thereby driving the discharge port of the material guide pipe 230 to swing smoothly laterally, achieving uniform distribution of coal particles in the target area and improving the uniformity of feeding.

[0051] In this embodiment, the lifting mechanism 100 includes a support frame 110 and a frame 120 inclinedly mounted on the support frame 110. Seven rotating rollers 130 are disposed inside the frame 120, and a lifting conveyor belt 140 surrounds the seven rotating rollers 130. A drive motor 150 is fixed to the outside of the frame 120, and the drive motor 150 is connected to the rotating rollers 130 to drive the lifting conveyor belt 140. A guide hopper 160 is fixed to the top of the frame 120, and the guide hopper 160 is located above the collection hopper 220.

[0052] The support frame 110 and frame 120, as the main structural load-bearing components, are welded from steel. The bottom of the support frame 110 can be provided with waist holes for easy fixing with foot anchors. The lifting conveyor belt 140 uses friction to move the coal particles upwards at an angle. The drive motor 150 provides power for the rotation of the rotating rollers 130; the drive motor 150 only needs to be connected to any one of the seven rotating rollers 130. The top of the frame 120 is welded to the guide hopper 160 for feeding the collection hopper 220.

[0053] Specifically, the support frame 110 and the inclined frame 120 form a stable load-bearing structure. The support frame 110 has waist holes at its bottom for easy foot fixing, improving the equipment's installation adaptability and overall stability. At least two rotating rollers 130 inside the frame 120 work in conjunction with the surrounding lifting conveyor belt 140, and a drive motor 150 fixed on the outside is connected to any of the rotating rollers 130, ensuring a highly efficient and reliable transmission structure. The guide hopper 160 fixed at the top of the frame 120 is located above the collection hopper 220, accurately guiding materials into the collection hopper 220, ensuring continuous and accurate feeding.

[0054] Combined with reference Figure 5 and Figure 6 As shown, in this embodiment, the outer side of the lifting conveyor belt 140 is provided with multiple connecting plates 170 at intervals. Each connecting plate 170 is rotatably connected to a baffle 180. The connecting plate 170 is provided with a limiting shoulder 171, which is used to limit the rotation angle of the baffle 180 to a range of 0 to 90 degrees.

[0055] Specifically, multiple connecting plates 170 are arranged at intervals along the conveying direction on the outer side of the lifting conveyor belt 140, and each connecting plate 170 is fixed relative to the conveyor belt. A baffle 180 is rotatably connected to each connecting plate 170, and the baffle 180 can rotate freely relative to the connecting plate 170 within a certain angle. A limiting shoulder 171 is provided on the connecting plate 170, and the limiting shoulder 171 is located on the rotation path of the baffle 180. Through cooperation with the baffle 180, the rotation angle of the baffle 180 is limited to the range of 0 to 90 degrees, preventing the baffle 180 from rotating excessively or flipping in the opposite direction. The baffle 180 is rotatable and limited within the range of 0 to 90 degrees. It can effectively block and support the material during the conveyor belt lifting process, reduce material slippage and backlash, and improve conveying stability and efficiency. It can also smoothly rotate and avoid interference with the equipment structure when the conveyor belt passes through the turning position. The spaced connecting plates 170 provide a stable installation base for the baffle 180, ensuring that each baffle 180 can rotate independently and flexibly.

[0056] Combined with reference Figure 7 and Figure 8 As shown, in this embodiment, multiple anti-slip strips 141 are arranged at intervals along the conveying direction on the surface of the lifting conveyor belt 140 between adjacent connecting plates 170, and the anti-slip strips 141 are fixedly connected to the surface of the conveyor belt. The guiding mechanism 200 also includes a support plate 240, which is fixedly installed at the front end of the support frame 110; a rotating plate 210 is rotatably mounted above the support plate 240, and the rotating plate 210 can rotate relative to the support plate 240 around a vertical axis. A support plate 250 is provided on the rotating plate 210 extending radially outward, and an arc-shaped bracket 251 is fixedly provided at the front end of the support plate 250. The arc-shaped profile of the arc-shaped bracket 251 is adapted to the shape of the guiding pipe 230, and is used to support and position the guiding pipe 230. The collecting hopper 220 is installed on the top of the rotating plate 210 by multiple supporting columns, and the lower part of the collecting hopper 220 is connected to the guiding pipe 230, so that materials can enter the guiding pipe 230 through the collecting hopper 220.

[0057] The anti-slip strips 141 on the surface of the lifting conveyor belt 140 effectively increase the friction between the material and the conveyor belt, reducing material slippage and slumping during the lifting process, and ensuring stable and reliable conveying. The support plate 240 provides stable support for the rotating plate 210 and its upper structure. The rotating plate 210 can rotate around its vertical axis, thus adjusting the guiding position as the transverse mechanism 330 moves to adapt to different guiding requirements. The arc-shaped bracket 251 at the front end of the support plate 250 matches the shape of the guiding pipe 230, providing reliable support and positioning for the guiding pipe 230, preventing pipe deviation or shaking. The collection hopper 220 is securely installed on top of the rotating plate 210 via support columns and is connected to the guiding pipe 230, enabling it to centrally receive materials and smoothly guide them into the guiding pipe 230.

[0058] In this embodiment, the material guiding pipe 230 includes a first pipe 231 and a second pipe 232. The upper end of the first pipe 231 is connected to the discharge port of the collecting hopper 220, and the lower end of the first pipe 231 is connected to the upper end of the second pipe 232. The discharge port of the second pipe 232 is connected to an elastic rubber tube 400, which is used to adapt to the swing of the discharge port and flexibly guide the material.

[0059] Specifically, the material guiding pipe 230 adopts a segmented structure. The upper end of the first pipe 231 is sealed and connected to the discharge port of the collecting hopper 220 to receive the material falling from the collecting hopper 220; the lower end of the first pipe 231 is fixedly connected to the upper end of the second pipe 232 to form a continuous material channel. The discharge port of the second pipe 232 is connected to an elastic rubber tube 400, which is sealed and assembled with the discharge port. The elastic rubber tube 400 guides and conveys the material through its flexible inner wall, reducing spillage or jamming of the material during the discharge swing process.

[0060] In this embodiment, the end frame 320 is fixedly mounted on the front end of the support frame 110, and a transverse movement mechanism 330 is provided on the top of the end frame 320. The transverse movement mechanism 330 includes a lead screw 331, a servo motor 332, and a moving slider 333. The lead screw 331 is rotatably mounted on the top of the end frame 320, the servo motor 332 is fixedly mounted on the end of the end frame 320, and its output end is connected to the lead screw 331. The moving slider 333 is threadedly connected to the lead screw 331, and a sliding collar 310 is fixedly provided on the top of the moving slider 333. A second pipe 232 is slidably arranged inside the sliding collar 310.

[0061] Furthermore, the top of the end frame 320 is provided with a guide rail, and the bottom of the movable slider 333 is provided with a guide groove that is adapted to the guide rail. The guide rail and the guide groove slide together to guide and limit the lateral movement of the movable slider 333.

[0062] Furthermore, the rubber hose is connected to the end of the second pipe 232 by a pipe clamp 500, and multiple axial guide grooves 410 are arranged around the rubber hose in the circumferential direction.

[0063] Specifically, the end frame 320 is fixed to the front end of the support frame 110 by welding, providing a stable mounting base for the lateral movement mechanism 330. The servo motor 332 drives the lead screw 331 to move the moving slider 333. With the sliding cooperation of the guide rail and the guide groove, the moving slider 333 can move laterally accurately and smoothly without deviation or wobbling.

[0064] The sliding collar 310 on the movable slider 333 slides in engagement with the second pipe 232, providing reliable support and guidance for the second pipe 232 during lateral movement. The elastic rubber tube 400 is securely connected to the end of the second pipe 232 via a pipe clamp 500, ensuring a tight connection and easy assembly / disassembly. Its circumferentially arranged axial guide groove 410 facilitates smoother material flow and reduces adhesion and accumulation. Simultaneously, the flexibility of the elastic rubber tube 400 allows for flexible material guidance by adapting to positional changes.

[0065] In this embodiment, a pad 600 is provided inside the frame 120. The pad 600 is provided with a plurality of arc-shaped mounting grooves 610. A plurality of rotating rollers 130 are respectively arranged in the plurality of arc-shaped mounting grooves 610. The pad 600 is used to support the lifting conveyor belt 140 between two adjacent rotating rollers 130.

[0066] The pad 600 inside the frame 120 provides stable support for the lifting conveyor belt 140, especially precisely supporting the conveyor belt section between two adjacent rotating rollers 130. This reduces excessive sagging and deformation of the conveyor belt due to its own weight or material pressure, ensuring smooth operation. The arc-shaped mounting groove 610 on the pad 600 allows for precise positioning and installation of the rotating rollers 130, limiting their offset and swaying, ensuring smooth rotation, and thus guaranteeing stable conveying by the lifting conveyor belt 140.

[0067] The core working principle of the coal mine feeding device provided in this embodiment is to transport ground coal particles to a designated height through the lifting mechanism 100, receive and directionally transport them through the guiding mechanism 200, and then drive the discharge port of the guiding pipe 230 to swing laterally through the swing mechanism 300, so as to achieve uniform distribution of coal in the loading truck.

[0068] The lifting mechanism 100, as the core of material lifting, consists of a support frame 110 and an inclined frame 120 forming a stable load-bearing structure. At least two rotating rollers 130 within the frame 120 are connected to an external drive motor 150. The drive motor 150 provides power to rotate the rotating rollers 130, thereby driving the lifting conveyor belt 140 surrounding the rotating rollers 130 to rotate at a uniform speed. Connecting plates 170 spaced apart on the outer side of the lifting conveyor belt 140 provide a stable mounting base for the baffles 180. The baffles 180 can rotate within a range of 0 to 90 degrees, forming a barrier and support for coal particles during the lifting process, preventing material slippage and backflow. When passing the turning position of the rotating rollers 130, they can smoothly avoid interference and jamming. Anti-slip strips 141 between adjacent connecting plates 170 increase the friction between the material and the conveyor belt, further improving the stability of the lifting process and reducing material slippage and backflow. The guide hopper 160 at the top of the frame 120 is precisely aligned with the collection hopper 220 below, ensuring that the material conveyed to the top by the lifting conveyor belt 140 can accurately fall into the collection hopper 220, completing the lifting and receiving of the material.

[0069] The material guiding mechanism 200 is responsible for receiving and directional conveying of materials. The support plate 240 is fixed to the front end of the support frame 110, providing stable support for the rotating plate 210 above. The rotating plate 210 can rotate around a vertical axis. The front end of the support plate 250 on the rotating plate 210 is provided with an arc-shaped bracket 251 that matches the shape of the material guiding pipe 230, providing reliable support and positioning for the material guiding pipe 230 and preventing it from shifting or shaking. The collection hopper 220 is firmly installed on the top of the rotating plate 210 by a support column. Its bottom is sealed and connected to the material guiding pipe 230, forming a continuous material channel. The material falls from the collection hopper 220 into the first pipe 231, and then is conveyed to the discharge port through the second pipe 232. The elastic rubber tube 400 at the end of the second pipe 232 adapts to the swing of the discharge port due to its flexibility, achieving flexible material guiding and reducing material spillage and jamming. The axial guide groove 410 on the rubber tube further ensures smooth material flow.

[0070] The swing mechanism 300 is used to achieve the lateral swing of the discharge port of the material guide pipe 230. The end frame 320 is fixed to the front end of the support frame 110, providing a foundation for the lateral movement mechanism 330. The servo motor 332 in the lateral movement mechanism 330 drives the lead screw 331 to rotate. The lead screw 331 is threadedly connected to the moving slider 333, which drives the moving slider 333 to move laterally along the guide rail at the top of the end frame 320. The guide rail slides and the guide groove at the bottom of the moving slider 333 to achieve guidance and limit, preventing the moving slider 333 from deviating and shaking. The sliding collar 310 at the top of the moving slider 333 is movably sleeved on the outside of the second pipe 232 and can slide along the second pipe 232. When the lateral movement mechanism 330 drives the sliding collar 310 to move laterally, it adaptively compensates for the displacement changes of the material guide pipe 230, ensuring that the material guide pipe 230 moves smoothly without jamming, thereby driving the discharge port of the material guide pipe 230 to swing laterally smoothly and achieve uniform distribution of coal particles.

[0071] Furthermore, the pad 600 inside the frame 120 provides stable support for the lifting conveyor belt 140 between two adjacent rotating rollers 130, preventing the conveyor belt from excessively sagging and deforming due to its own weight or material pressure. The arc-shaped mounting groove 610 on the pad 600 precisely positions the rotating rollers 130, limiting their offset and swaying, ensuring smooth rotation of the rotating rollers 130, and guaranteeing the stable operation of the lifting conveyor belt 140. The elastic rubber tube 400 is securely connected to the end of the second pipe 232 through the pipe clamp 500, ensuring a tight connection while facilitating disassembly and maintenance.

[0072] Based on the above working principle, the specific working method of the feeding device used in this coal mine is as follows:

[0073] Step 1: Equipment Debugging. First, check the installation of each component of the device, confirming that the support frame 110 is firmly fixed to the foot through the bottom waist hole, and that the frame 120 is tightly welded to the support frame 110. Check that each rotating roller 130 is accurately installed in the arc-shaped mounting groove 610 of the pad 600, and that the lifting conveyor belt 140 has appropriate tension and no deviation. Confirm that the collecting hopper 220 and the guiding pipe 230 are sealed and connected, that the elastic rubber tube 400 is tightly connected to the end of the second pipe 232 through the pipe clamp 500, and that the arc-shaped bracket 251 supports the guiding pipe 230 in place. Check that the lead screw 331 in the transverse mechanism 330 rotates flexibly, that the servo motor 332 is reliably connected to the lead screw 331, that the guide groove at the bottom of the moving slider 333 slides smoothly with the guide rail at the top of the end frame 320, and that the sliding collar 310 is fitted on the outside of the second pipe 232 and can slide freely. Adjust the rotating disk 210 to ensure it rotates flexibly around the vertical axis of the support disk 240, and that the collecting hopper 220 is precisely aligned with the guide hopper 160 at the top of the frame 120. After adjustment, start the drive motor 150 and servo motor 332 and run them under no-load for a period of time to confirm that there is no jamming or abnormal noise in the operation of each component.

[0074] The second step is material lifting. After normal no-load operation, stop the equipment and evenly spread the coal particles on the ground onto the feed end of the lifting conveyor belt 140. Start the drive motor 150, which drives the rotating roller 130 connected to it to rotate. The rotating roller 130 drives the lifting conveyor belt 140 to rotate upward at a uniform speed. During the lifting process, the baffles 180 on the conveyor belt maintain a suitable angle of 90 degrees under the restriction of the limiting shoulder 171, forming a blocking and supporting effect on the coal particles. The anti-slip strips 141 increase the friction between the material and the conveyor belt, further preventing the material from slipping and ensuring that the material is stably conveyed upward with the conveyor belt. When the material is conveyed to the top of the frame 120, it falls into the guide hopper 160 under the guidance of the conveyor belt, and is precisely guided by the guide hopper 160 to the collection hopper 220 below, completing the material lifting process.

[0075] The third step is material conveying. After the coal particles falling from the guide hopper 160 are received by the collecting hopper 220, the material enters the first pipe 231 connected to the bottom of the collecting hopper 220 under its own gravity. It is then conveyed through the first pipe 231 to the second pipe 232, and then conveyed towards the discharge port through the second pipe 232. During this process, the arc-shaped bracket 251 continuously supports and positions the second pipe 232 to prevent the pipe from shifting or shaking, ensuring that the material is smoothly conveyed in the guide pipe 230 without any jamming.

[0076] The fourth step is to evenly distribute the material. The servo motor 332 of the transverse mechanism 330 is activated. The servo motor 332 drives the lead screw 331 to rotate. The lead screw 331 drives the threadedly connected movable slider 333 to move smoothly laterally along the guide rail. The sliding collar 310 at the top of the movable slider 333 moves laterally synchronously with the movable slider 333. At the same time, the sliding collar 310 slides along the second pipe 232, adaptively compensating for the displacement changes of the material guide pipe 230 and preventing jamming. The sliding collar 310 drives the second pipe 232 to swing laterally synchronously. The elastic rubber tube 400 at the end of the second pipe 232 adapts to the swing angle due to its flexibility, achieving flexible material guidance. The axial guide groove 410 on the rubber tube makes the material flow smoother, reducing material adhesion, accumulation, and spillage. By controlling the operating speed and forward / reverse direction of the servo motor 332, the lateral movement speed and range of the moving slider 333 are adjusted, thereby controlling the swing amplitude and frequency of the discharge port of the material guide pipe 230, so that the coal particles are evenly distributed and loaded into the truck bed, completing the entire feeding process.

[0077] Step 5: Shut down the equipment. After feeding is completed, stop adding material to the feeding end of the lifting conveyor belt 140. After all the material on the lifting conveyor belt 140 has been conveyed to the collection hopper 220 and discharged through the material guide pipe 230, turn off the drive motor 150 and the servo motor 332.

[0078] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this embodiment are only used to explain the relative positional relationship and movement of each component in a specific posture (as shown in the attached figure). If the specific posture changes, the directional indicator will also change accordingly.

[0079] Furthermore, in this embodiment, the use of terms such as "first" and "second" is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. In the description of this embodiment, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0080] In this embodiment, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this embodiment according to the specific circumstances.
