[0026] This utility model proposes a coal corridor cleaning device, which aims to use a first scraper and a second scraper to scrape away debris from the conveyor belt, resulting in more comprehensive cleaning, higher efficiency, and saving time and effort.

[0027] Please see Figures 1 to 3 In one embodiment of this utility model, the coal conveying corridor cleaning device 10 includes:

[0028] The corridor body 1 forms a receiving cavity 11 with an inlet 111 and an outlet 112 at both ends, and a conveyor belt 2 is provided inside the receiving cavity 11.

[0029] The cleaning assembly 3 includes a mounting frame 31, a lifting drive 32, a first scraper 33, and a second scraper 34. The mounting frame 31 is installed in the receiving cavity 11. The first scraper 33 and the second scraper 34 are spaced apart from each other on the mounting frame 31. The first scraper 33 is located near the feed inlet 111, and the second scraper 34 is located near the discharge outlet 112. The lifting drive 32 is installed in the receiving cavity 11 to drive the mounting frame 31 to lift. The first scraper 33 and the second scraper 34 are used to scrape away debris from the conveyor belt 2.

[0030] In this embodiment, the coal conveying corridor cleaning device 10 includes a corridor body 1 and a cleaning component 3. The corridor body 1 forms a receiving cavity 11 with an inlet 111 and an outlet 112 at both ends, and a conveyor belt 2 is provided inside the receiving cavity 11. The cleaning component 3 includes a mounting frame 31, a lifting drive component 32, a first scraper 33, and a second scraper 34. The mounting frame 31 is installed inside the receiving cavity 11. The first scraper 33 and the second scraper 34 are spaced apart from each other on the mounting frame 31. The first scraper 33 is located near the inlet 111, and the second scraper 34 is located near the outlet 112. It should be noted that the first scraper 33... 3. When the first scraper 33 and the second scraper 34 are working, the conveyor belt 2 is in operation. This facilitates the cleaning of the moving belt by the first scraper 33 and the second scraper 34. The first scraper 33 is located near the feed inlet 111, and the second scraper 34 is located near the discharge outlet 112. That is, the first scraper 33 performs preliminary cleaning of the conveyor belt 2, and then the second scraper 34 performs secondary cleaning. This ensures that the conveyor belt 2 is completely cleaned while removing debris twice, resulting in more comprehensive cleaning, higher efficiency, and saving time and labor.

[0031] Meanwhile, the cleaning assembly 3 also includes a lifting drive 32, which is installed in the receiving cavity 11 to drive the mounting frame 31 to rise and fall, so that the first scraper 33 and the second scraper 34 rise and fall relative to the conveyor belt 2, thereby effectively cleaning the conveyor belt 2 in a timely manner without affecting the normal operation of the conveyor belt 2.

[0032] In one implementation, please refer to Figures 1 to 3 The mounting bracket 31 is provided with two oppositely arranged mounting holes 311;

[0033] The first scraper 33 includes a connecting rod 331, a connecting frame 332, and a plurality of cleaning brushes 333. The connecting frame 332 is mounted on the connecting rod 331, and the plurality of cleaning brushes 333 are spaced apart on the connecting frame 332. The two ends of the connecting rod 331 are respectively inserted through the two mounting holes 311.

[0034] In this embodiment, the first scraper 33 includes a connecting rod 331, a connecting frame 332, and multiple cleaning brushes 333. The connecting frame 332 is mounted on the connecting rod 331. Simultaneously, the mounting frame 31 has two oppositely arranged mounting holes 311, meaning that both ends of the connecting rod 331 pass through the two mounting holes 311 respectively, thereby achieving stable mounting of the first scraper 33 on the mounting frame 31. It should be noted that during the cleaning process, the conveyor belt 2 is in operation. Thus, the conveyor belt 2 can drive the multiple cleaning brushes 333 to rotate, and while rotating, the multiple cleaning brushes 333 can brush away debris from the conveyor belt 2, thereby achieving cleaning of the conveyor belt 2.

[0035] In one implementation, please refer to Figures 1 to 3 The two mounting holes 311 are elongated, which allows multiple cleaning brushes 333 to be raised and lowered relative to the mounting frame 31, so that the multiple cleaning brushes 333 can fit more closely to the surface of the conveyor belt 2, thereby cleaning the conveyor belt 2 better.

[0036] In one implementation, please refer to Figures 1 to 3 The cleaning assembly 3 further includes a first spray element 35, which is mounted on the mounting bracket 31 and positioned above the first scraper 33. This arrangement, combined with the scraping action of the first scraper 33 and the water spraying action of the first spray element 35, allows for more thorough cleaning of debris on the conveyor belt 2. It should be noted that the first spray element 35 is prior art and is not considered a limitation herein.

[0037] In one implementation, please refer to Figures 1 to 3 The second scraping component 34 includes a drive motor 341, a connecting plate 342, and a scraper 343. The drive motor 341 is driven and connected to the connecting plate 342, and the scraper 343 is installed on the connecting plate 342. Driven by the drive motor 341, the scraper 343 can move closer to or away from the conveyor belt 2. When it moves closer, the scraper 343 can scrape off the debris on the conveyor belt 2. When it moves away, it does not affect the normal use of the conveyor belt 2.

[0038] In one implementation, please refer to Figures 1 to 3The second scraper 34 also includes two guide rails and two guide sliders. The two guide rails are installed at intervals on the connecting plate 342, and the two guide sliders are installed at intervals on the scraper 343. Each guide slider is connected to each guide rail. Through the mutual cooperation between the two guide rails and the two guide sliders, the scraper 343 can move closer to or away from the conveyor belt 2 more smoothly.

[0039] In one implementation, please refer to Figures 1 to 3 The coal conveyor corridor cleaning device 10 further includes a second spray element 4, which is installed on the side wall of the receiving cavity 11 and located above the scraper 343. This arrangement, combined with the scraping action of the second scraper 34 and the water spraying action of the second spray element 4, allows for more thorough cleaning of debris on the conveyor belt 2. It should be noted that the second spray element 4 is prior art and is not limited thereto in this application.

[0040] In one implementation, please refer to Figures 1 to 3 The lifting drive component 32 includes a drive motor 321, a gear transmission assembly, a lifting screw, and a lifting block 322. The drive motor 321 is driven and connected to the gear transmission assembly, which is driven and connected to the lifting screw. One side of the lifting block 322 is threaded to the lifting screw, and the other side is connected to the mounting frame 31. It should be noted that the gear transmission assembly includes a driving gear and a driven gear. The drive motor 321 is driven and connected to the driving gear, which meshes with the driven gear. The driven gear is mounted on the lifting screw. Driven by the drive motor 321, the lifting screw can be smoothly rotated. Simultaneously, the lifting screw rotates, causing the lifting block 322 to rise and fall, thereby causing the mounting frame 31 to rise and fall, thus moving the first scraper 33 and the second scraper 34 closer to or further away from the conveyor belt 2.

[0041] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
