Technical Field

[0001] This utility model relates to the technical field of scraper conveyor cleaning devices, and in particular to an automatic cleaning device for the chute of a mining scraper conveyor. Background Technology

[0002] Mining scraper conveyors, as key equipment for underground coal transportation, occupy an important position in the coal industry. In the early days, coal mining was small-scale and transportation needs were simple, leading to the development of scraper conveyors. With their simple structure and low cost, they enabled the initial transfer of coal from the working face to the transportation roadway.

[0003] When materials are conveyed in the chute, they are easily stuck and accumulated on the inner wall of the chute due to friction, moisture and other factors. This not only reduces the conveying efficiency, but may also cause malfunctions such as scraper jamming and chain breakage, which seriously affects the continuity of production. In the early days, cleaning the chute mainly relied on manual labor, using simple tools to manually scrape off the stuck materials, which caused the equipment to be shut down for a long time and reduced production efficiency. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an automatic cleaning device for the chute of a mining scraper conveyor, which aims to improve the problem of relying on manual scraping of sticky materials with simple tools, which causes the equipment to be shut down for a long time and reduces production efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic cleaning device for a mining scraper conveyor chute, comprising a feeding pipe, a placement shell attached to the outer wall of the feeding pipe, a connecting shell fixedly connected to the outer wall of the placement shell, a motor fixedly connected to the upper surface of the connecting shell, a positive and negative lead screw provided at the output end of the motor, a limit post attached to the outer wall of the positive and negative lead screw, a sliding block fixedly connected to the outer wall of the limit post, a connecting rod fixedly connected to the outer wall of the sliding block, a scraper plate fixedly connected to the outer wall of the connecting rod, and a blocking component provided on the outer wall of the connecting rod for blocking materials.

[0006] Preferably, the blocking assembly includes a baffle, the outer wall of which is fixedly connected to both sides of the outer wall of the connecting rod, and the outer wall of the baffle is slidably connected to the inner wall of the feed pipe.

[0007] Preferably, the length of the baffle is equal to the distance the connecting rod moves, the outer wall of the sliding block is slidably connected to the inner wall of the connecting housing, and the outer wall of the scraper is slidably connected to the inner wall of the feeding pipe.

[0008] Preferably, the outer wall of the scraper is provided with an inclined surface, which is used to scrape off the material.

[0009] Preferably, a fixing plate is fixedly connected to the outer wall of the feeding pipe, a hydraulic cylinder is provided on the upper surface of the fixing plate, a column is fixedly connected to the output end of the hydraulic cylinder, a fixing column one is fixedly connected to the inner wall of the column, a connecting bracket one is rotatably connected to the outer wall of the fixing column one, a limit rod is rotatably connected to the outer wall of the connecting bracket one, a locking block is rotatably connected to the outer wall of the limit rod, a connecting rod is rotatably connected to the inner wall of the fixing column one, a connecting bracket two is rotatably connected to the outer wall of the connecting rod, and a fixing column two is rotatably connected to the outer wall of the connecting bracket two.

[0010] Preferably, the outer wall of the second fixing column is fixedly connected to the upper surface of the fixing plate, and the inner wall of the locking block is rotatably connected to the outer wall of the second connecting bracket.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, the starting motor drives the positive and negative lead screws to rotate, causing the limiting pin to move along the thread on the outer wall of the lead screw, which in turn drives the sliding block to move on the inner wall of the connecting housing, thereby pulling the connecting rod and the scraper to move on the inner wall of the feeding pipe. The scraper scrapes off the sticky material, and at the same time the connecting rod drives the baffle to move to prevent the material from falling out, thereby cleaning the inner wall of the feeding pipe and avoiding the material sticking and affecting the feeding effect.

[0015] 2. In this utility model, the hydraulic cylinder is activated to push the column and the fixed column to move, which in turn drives the connecting bracket and the connecting rod to move. When the connecting bracket moves, the limiting rod drives the locking block to move. Constrained by the axis of the connecting bracket, the locking block rotates, and the connecting rod pulls the connecting bracket to rotate, making the locking block tend to be horizontal.

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

[0025] Reference Figure 1 , Figure 4 and Figure 5 An embodiment of this utility model provides an automatic cleaning device for the chute of a mining scraper conveyor, comprising a feeding pipe 1, a placement shell 2 attached to the outer wall of the feeding pipe 1, a connecting shell 3 fixedly connected to the outer wall of the placement shell 2, a motor 4 fixedly connected to the upper surface of the connecting shell 3, a positive and negative lead screw 5 provided at the output end of the motor 4, a limit post 7 attached to the outer wall of the positive and negative lead screw 5, a sliding block 6 fixedly connected to the outer wall of the limit post 7, a connecting rod 8 fixedly connected to the outer wall of the sliding block 6, a scraper plate 9 fixedly connected to the outer wall of the connecting rod 8, and a blocking component provided on the outer wall of the connecting rod 8 for blocking materials.

[0026] Specifically, by placing the placement shell 2 on the outer wall of the feeding pipe 1, the placement shell 2 and the connecting shell 3 are initially limited. The motor 4 is started to drive the positive and negative lead screws 5 to rotate, which in turn drives the limiting post 7 to slide in the threaded groove on the outer wall of the positive and negative lead screws 5. This causes the sliding block 6 to move on the inner wall of the connecting shell 3, thereby driving the connecting rod 8 and the scraper 9 to move. The scraper 9 scrapes off the material adhering to the inner wall of the feeding pipe 1, thereby cleaning the inner wall of the feeding pipe 1 and preventing the material adhering to the inner wall from affecting the feeding effect.

[0027] Reference Figure 2 and Figure 3 The blocking assembly includes a baffle 10, the outer wall of which is fixedly connected to both sides of the outer wall of the connecting rod 8, and the outer wall of the baffle 10 is slidably connected to the inner wall of the feed pipe 1. The length of the baffle 10 is equal to the distance the connecting rod 8 moves. The outer wall of the sliding block 6 is slidably connected to the inner wall of the connecting housing 3, and the outer wall of the scraper 9 is slidably connected to the inner wall of the feed pipe 1.

[0028] Specifically, by setting the baffle 10 on the inner wall of the feed pipe 1, when the connecting rod 8 moves up and down, the scraper 9 moves synchronously with the connecting rod 8, blocking the through groove on the outer wall of the feed pipe 1, preventing the material on the inner wall of the feed pipe 1 from flowing out. The length of the baffles 10 on both sides can completely block the distance the connecting rod 8 moves without detaching from the inner wall of the feed pipe 1. When the sliding block 6 moves on the inner wall of the connecting housing 3, the outer walls around the sliding block 6 fit against the connecting housing 3, preventing the positive and negative screws 5 from driving the sliding block 6 to rotate.

[0029] Reference Figure 4 The outer wall of the scraper 9 is provided with a slope, which is used to scrape off the material.

[0030] Specifically, by setting the inclined surface of the scraper 9, the friction between the scraper 9 and the inner wall of the discharge pipe 1 during operation is reduced, thereby reducing the wear of the scraper 9 and the chute, extending the service life of the equipment, and reducing the frequency and cost of equipment maintenance and replacement of parts.

[0031] Reference Figure 1 , Figure 2 and Figure 6A fixing plate 11 is fixedly connected to the outer wall of the feeding pipe 1. A hydraulic cylinder 12 is installed on the upper surface of the fixing plate 11. A column 13 is fixedly connected to the output end of the hydraulic cylinder 12. A fixing column 14 is fixedly connected to the inner wall of the column 13. A connecting bracket 15 is rotatably connected to the outer wall of the fixing column 14. A limit rod 16 is rotatably connected to the outer wall of the connecting bracket 15. A locking block 17 is rotatably connected to the outer wall of the limit rod 16. A connecting rod 18 is rotatably connected to the inner wall of the fixing column 14. A connecting bracket 19 is rotatably connected to the outer wall of the connecting bracket 19. A fixing column 20 is rotatably connected to the outer wall of the connecting bracket 20. The outer wall of the fixing column 20 is fixedly connected to the upper surface of the fixing plate 11. The inner wall of the locking block 17 is rotatably connected to the outer wall of the connecting bracket 29. The connecting rod 18 is connected to the shaft in the middle of the connecting bracket 29. The locking block 17 is connected to the shaft of the connecting bracket 29 near the column 13. Slots 21 are provided on both sides of the outer wall of the housing 2. The outer wall of the card block 17 is attached to the outer wall of the card slot 21.

[0032] Specifically, the hydraulic cylinder 12, which is securely fixed by the fixing plate 11, is activated. The hydraulic cylinder 12 starts to operate, pushing the column 13 and the first fixing column 14 to move smoothly, thereby driving the first connecting bracket 15 and the connecting rod 18 to move synchronously. When the first connecting bracket 15 moves, the limiting rod 16 moves accordingly, thereby driving the locking block 17 to move. Since the locking block 17 is constrained by the shaft of the second connecting bracket 19, it will rotate during the movement. When the connecting rod 18 moves, it will drive the second connecting bracket 19 to rotate, further pulling the locking block 17 to gradually approach a horizontal state. The second fixing column 20 provides support and limit for the second connecting bracket 19. Finally, the locking block 17 is locked in the inner wall of the slot 21, realizing the firm fixation of the housing 2, so that the housing 2 can be easily installed and disassembled, effectively improving work efficiency.

[0033] Working principle: When this device is needed, first place the placement shell 2 on the outer wall of the feeding pipe 1, so that the feeding pipe 1 is embedded in the outer wall of the placement shell 2. Start the hydraulic cylinder 12 fixed by the fixing plate 11. The hydraulic cylinder 12 pushes the column 13 and the fixing column 14 to move, which in turn drives the connecting bracket 15 and the connecting rod 18 to move. When the connecting bracket 15 moves, it drives the limiting rod 16 to move, which in turn drives the locking block 17 to move. Since the locking block 17 is restricted by the shaft of the connecting bracket 2 19, it drives the locking block 17 to rotate. When the connecting rod 18 moves, it drives the connecting bracket 2 19 to rotate, which pulls the locking block 17 to a horizontal state. The fixing column 20 supports and limits the connecting bracket 2 19, so that the locking block 17 is locked in the inner wall of the slot 21, fixing the placement shell 2, so as to facilitate the installation and disassembly of the placement shell 2 and improve work efficiency.

[0034] After the housing 2 is fixed, the motor 4 is started to drive the positive and negative lead screws 5 to rotate, which causes the limiting post 7 to move in the thread on the outer wall of the positive and negative lead screws 5. This causes the sliding block 6 to move on the inner wall of the connecting housing 3, which in turn causes the connecting rod 8 and the scraper 9 to move on the inner wall of the feeding pipe 1. This allows the scraper 9 to scrape off the material adhering to the inner wall of the feeding pipe 1 and drop it off through the inclined surface of the scraper 9. When the connecting rod 8 moves, it will simultaneously drive the baffle 10 to move on the inner wall of the feeding pipe 1 to prevent the material from falling out. This achieves the purpose of cleaning the inner wall of the feeding pipe 1 and preventing the material adhering to the inner wall from affecting the feeding effect.

[0035] This device not only facilitates the installation, disassembly, and placement of the housing 2, thus improving work efficiency, but also cleans the inner wall of the feeding pipe 1, preventing materials adhering to the inner wall from affecting the feeding effect.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
