Description

Technical Field

[0001] This utility model relates to the field of coal bunker anti-blocking technology, and in particular to a coal bunker anti-blocking device with lifting and unloading buffer. Background Technology

[0002] In the field of coal storage, transportation, and processing, coal bunkers serve as crucial transit facilities, and the smoothness and buffering performance of their unloading process directly impact production efficiency and equipment safety. With the large-scale development of the coal industry, coal bunkers are prone to problems such as coal blockage of the discharge pipe and damage to receiving devices due to unloading impacts. Traditional anti-blockage devices, due to their low unblocking efficiency and poor buffering effect, are no longer sufficient to meet the demands of modern coal production for continuous operation and equipment protection. Therefore, technological innovation is urgently needed to achieve efficient unblocking of the discharge pipe and buffering protection during the unloading process.

[0003] Existing coal bunker anti-clogging technologies have significant drawbacks: First, the unblocking methods are inefficient. Traditional devices often rely on manual tapping or fixed material-push rods, failing to achieve continuous automatic unblocking. Coal chunks easily accumulate and clog the discharge pipe, leading to unloading interruptions. Second, unloading buffers are lacking. When coal chunks fall directly from the discharge pipe, the concentrated impact force easily causes deformation and damage to the bottom receiving devices (such as conveyor belts and coal storage hoppers), increasing maintenance costs. Third, component maintenance is difficult. The material distribution buffer structure is mostly fixed, requiring machine shutdown and disassembly of the main coal bunker for replacement after wear, affecting production efficiency. Furthermore, non-automated unblocking mechanisms cannot adapt to the unloading requirements of coal chunks of different sizes, resulting in unstable anti-clogging effects. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a coal bunker anti-blocking device with improved unloading buffer, which aims to solve the problems of easy blockage of the coal discharge pipe, large unloading impact, and difficult maintenance of the material distribution cone during coal unloading.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A coal bunker anti-blocking device for lifting unloading buffer includes a coal discharge pipe. Multiple grooves are formed at the middle of the outer wall of the coal discharge pipe, and through holes are formed on adjacent sides of the multiple grooves. A clearing component is installed inside each groove. Rotating grooves are formed at the bottom ends of both the front and rear sides of the coal discharge pipe, and limiting components are installed inside each rotating groove. An installation ring is provided on the bottom side of the coal discharge pipe, and multiple connecting rods are fixedly connected to the bottom side of the installation ring. A material distribution cone is fixedly connected to the bottom side of each of the multiple connecting rods.

[0007] Furthermore, the unblocking component includes a sloping slider, and a connecting rod 2 is fixedly connected to one of the adjacent sides of the plurality of sloping sliders. The outer wall of the connecting rod 2 is slidably connected to the inside of the through hole, and a telescopic rod is fixedly connected to one of the adjacent sides of the plurality of connecting rod 2.

[0008] Furthermore, a spring is provided inside the groove, one end of the spring being connected to a nearby side of one of the multiple grooves, and the other end being connected to a nearby side of one of the multiple inclined sliders.

[0009] Furthermore, a mounting frame is fixedly connected to the top right side of the coal discharge pipe, a motor is installed inside the mounting frame, a rotating rod is fixedly connected to the drive end of the motor, and a gear is fixedly connected to the bottom end of the outer wall of the rotating rod.

[0010] Furthermore, a toothed ring is rotatably connected to the middle end of the outer wall of the coal discharge pipe, the toothed ring meshes with the gear, and multiple abutment rods are fixedly connected to the bottom side of the toothed ring.

[0011] Furthermore, the bottom ends of both sides of the coal discharge pipe are provided with sliding grooves, and sliders are slidably connected inside the sliding grooves. Fixed rings are fixedly connected to the opposite sides of the sliders at both ends.

[0012] Furthermore, the limiting component includes an L-shaped plate, the top ends of the L-shaped plates at both ends being connected to the adjacent sides of the rotating grooves at both ends via a rotating shaft, and the bottom ends of the L-shaped plates at both ends being fixedly connected to a limiting rod.

[0013] Furthermore, mounting pieces are fixedly connected to both ends of the top side of the mounting ring. A limiting groove is formed inside the mounting piece, the outer wall of the mounting piece is located inside the rotating groove, and the outer wall of the limiting rod is located inside the limiting groove.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, when unloading coal, the starting motor drives the rotating rod to rotate the gear. The gear meshes with the gear ring to rotate the abutment rod. The abutment rod pushes the inclined slider to move the telescopic rod, clearing the coal in the coal discharge pipe. After the abutment rod leaves, the spring drives the telescopic rod to reset, realizing repeated clearing and preventing coal bunker blockage.

[0016] 2. In this invention, coal falling onto the top side of the distribution cone is divided into multiple portions that fall from all sides, reducing the impact on the bottom receiving device. During replacement, the fixing ring is slid upwards, and the L-shaped plate is rotated to disengage the limiting rod from the limiting groove, releasing the fixing of the distribution cone and facilitating disassembly and replacement, ensuring the continuous and effective distribution and buffering effect.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1 and Figure 2This utility model provides an embodiment of a coal bunker anti-blocking device for lifting and unloading buffering, including a coal discharge pipe 1. Multiple grooves are formed at the middle of the outer wall of the coal discharge pipe 1, and through holes are formed on adjacent sides of the multiple grooves. Inclined sliders 13 are arranged inside the grooves. Rotating grooves 12 are formed at the bottom ends of both the front and rear sides of the coal discharge pipe 1. L-shaped plates 22 are arranged inside the rotating grooves 12. An installation ring 11 is provided on the bottom side of the coal discharge pipe 1. Multiple connecting rods 9 are fixedly connected to the bottom side of the installation ring 11. A material distribution cone 10 is fixedly connected to the bottom side of the multiple connecting rods 9. Connecting rods 17 are fixedly connected to adjacent sides of the multiple inclined sliders 13. The outer wall of the second 17 is slidably connected to the inside of the through hole. Multiple connecting rods 17 are fixedly connected to telescopic rods 16 on their adjacent sides. A spring 18 is installed inside the groove. One end of the spring 18 is connected to the adjacent side of multiple grooves, and the other end is connected to the adjacent side of multiple inclined sliders 13. The top right side of the coal discharge pipe 1 is fixedly connected to the mounting bracket 2. The mounting bracket 2 is installed inside the motor 3. The drive end of the motor 3 is fixedly connected to the rotating rod 4. The bottom end of the outer wall of the rotating rod 4 is fixedly connected to the gear 5. The middle end of the outer wall of the coal discharge pipe 1 is rotatably connected to the toothed ring 15. The toothed ring 15 and the gear 5 mesh with each other. Multiple abutment rods 6 are fixedly connected to the bottom side of the toothed ring 15.

[0026] Specifically, when using this type of coal bunker anti-blockage device with lifting and unloading buffer, the operation process revolves around coal unloading and unblocking, buffer material distribution, and component replacement. When unloading coal from the coal discharge pipe 1, the starting motor 3 drives the rotating rod 4 to rotate the gear 5. Through the meshing of the gear 5 and the gear ring 15, the gear ring 15 and the bottom abutment rod 6 rotate. When the abutment rod 6 rotates, it contacts the inclined slider 13, pushing it to move and driving the connecting rod 17 and the telescopic rod 16 to move, thus unblocking the coal in the coal discharge pipe 1. When the abutment rod 6 pushes the inclined slider 13, it compresses the spring 18. When the abutment rod 6 no longer abuts the inclined slider 13, the spring 18 drives the telescopic rod 16 and the inclined slider 13 to reset, realizing the repeated movement of the telescopic rod 16 to continuously unblock the blockage.

[0027] Reference Figure 3-5 The bottom ends of both sides of the coal discharge pipe 1 are provided with sliding grooves 7. Sliding blocks 14 are slidably connected inside the sliding grooves 7. Fixed rings 8 are fixedly connected to the opposite sides of the sliding blocks 14 at both ends. The top ends of the L-shaped plates 22 at both ends are connected to the opposite sides of the rotating grooves 12 at both ends through rotating shafts 21. Limiting rods 23 are fixedly connected to the bottom ends of the L-shaped plates 22 at both ends. Mounting plates 19 are fixedly connected to the left and right ends of the top side of the mounting ring 11. Limiting grooves 20 are opened inside the mounting plates 19. The outer wall of the mounting plates 19 is located inside the rotating grooves 12. The outer wall of the limiting rods 23 is located inside the limiting grooves 20.

[0028] Specifically, after the coal falls to the top of the distribution cone 10, it is divided into multiple portions that fall from all sides, reducing the impact on the bottom receiving device during unloading. When replacing the distribution cone 10, slide the fixing ring 8 upwards to release the restriction on the L-shaped plate 22, rotate the L-shaped plate 22 to make the limiting rod 23 leave the limiting groove 20, and release the fixing of the mounting plate 19, mounting ring 11, and distribution cone 10, allowing for disassembly and replacement. This device, through its gear-driven unblocking structure and the distribution cone's buffer design, achieves anti-blocking and unloading buffering during coal bunker unloading, and facilitates the replacement of the distribution cone 10.

[0029] Working principle: When unloading coal from the coal discharge pipe 1, the motor 3 drives the rotating rod 4 to rotate the gear 5. Since the gear 5 and the gear ring 15 mesh with each other, the gear 5 will simultaneously drive the gear ring 15 and the abutment rod 6 on the bottom side of the gear ring 15 to rotate. When the abutment rod 6 rotates, it will contact the inclined plane slider 13, thereby pushing the inclined plane slider 13 to move. At the same time, it will drive the connecting rod 17 and the telescopic rod 16 to move. Then, the telescopic rod 16 can clear the coal inside the coal discharge pipe 1. At the same time, when the abutment rod 6 pushes the inclined plane slider 13 to move, it will compress the spring 18. Therefore, the abutment rod 6 no longer abuts the inclined plane slider. At 13 o'clock, the spring 18 will drive the telescopic rod 16 and the inclined slider 13 to reset, so that the telescopic rod 16 can move repeatedly. After the coal falls to the top side of the distribution cone 10, it will be divided into multiple parts by the distribution cone 10, so that the distribution cone 10 falls around its perimeter, thereby reducing the impact on the bottom receiving device during unloading. When the distribution cone 10 needs to be replaced, first slide the fixing ring 8 upward to release the limit on the L-shaped plate 22. Then, by rotating the L-shaped plate 22 and making the limiting rod 23 leave the inside of the limiting groove 20, the fixing of the mounting plate 19, the mounting ring 11 and the distribution cone 10 can be released, and the distribution cone 10 can be disassembled and replaced.
