[0016] 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.

[0017] Reference Figures 1-3 This utility model provides an embodiment of an improved structure for preventing coal falling from a coal conveyor belt used in power plant production. It includes a support frame 1, with fixed plates 3 fixedly connected to both the left and right sides of the upper part of the support frame 1. Mounting rods 4 are rotatably connected to both the left and right sides inside the fixed plates 3. A pulley 7 is fixedly connected to the front of the outer side of the mounting rods 4, and a conveyor roller 5 is fixedly connected to the outer side of the mounting rods 4. A conveyor belt 6 is provided outside the conveyor roller 5, and barrier belts 8 are fixedly connected to the front and rear sides of the outer side of the conveyor belt 6. A sliding block 12 is slidably connected inside the fixed plates 3 on opposite sides. Support plates 2 are fixedly connected to both the front and rear sides of the lower part of the support frame 1. A motor 9 is fixedly connected to the rear left side of the rear fixed plate 3, and the output end of the motor 9 is fixedly connected to the left mounting rod 4. A material collection component is provided on the opposite side of the sliding block 12 for collecting coal ash. The receiving assembly includes a receiving frame 13, which is fixedly connected to the opposite side of the sliding block 12. A filter screen 16 is fixedly connected to the middle of the inner wall of the receiving frame 13, and a baffle 15 is fixedly connected to the lower part of the inner wall of the receiving frame 13. A handle 14 is fixedly connected to the right side of the receiving frame 13. Vent holes are evenly opened in the middle of the baffle 15. A feeding assembly is provided on the lower right side of the support frame 1 for feeding coal ash. The feeding assembly includes a blower 17, which is fixedly connected to the lower right side of the support frame 1. An air intake pipe 18 is fixedly connected to the input end of the blower 17, and an air delivery pipe 19 is fixedly connected to the output end of the blower 17. Mounting blocks 10 are fixedly connected to the middle of the right side of the opposite side of the fixed plate 3. A scraper 11 is fixedly connected to the opposite side of the mounting block 10. The end of the air intake pipe 18 away from the blower 17 passes through the support frame 1.

[0018] When it is necessary to collect coal ash adhering to the surface of the coal conveyor belt used in power plant production, the scraper 11 first scrapes the surface of the conveyor belt 6 by the operation of the conveyor belt 6, removing the coal ash adhering to the surface and dispersing it into the air. The blower 17 is started to operate the suction pipe 18, which draws a vacuum to the lower inner side of the receiving frame 13. With the help of the vacuum, the coal ash and dust carried in the air are quickly sucked into the receiving frame 13. The dust is effectively filtered by the filter screen 16, and the filtered air is discharged, while the coal ash is retained in the receiving frame 13. Finally, by pulling the handle 14, the handle 14 moves the receiving frame 13 away from the support frame 1, realizing the automatic collection of coal ash adhering to the surface of the coal conveyor belt, improving energy utilization efficiency, reducing the environmental impact of coal ash, and improving the working efficiency of the equipment and the convenience of coal ash recycling.

[0019] Reference Figures 1-3 The support frame 1 is made of stainless steel, the fixing plate 3 is made of carbon steel, and the barrier strip 8 is made of rubber.

[0020] By using stainless steel, the mechanical load, corrosion resistance, and stability of the support frame 1 are improved, enabling it to withstand greater working pressure and the effects of long-term exposure to harsh environments, ensuring the long-term stable operation of the equipment. By using carbon steel, the strength of the fixing plate 3 is improved, allowing it to better resist external impacts and loads, extending its service life. By using rubber, the wear resistance of the barrier belt 8 is ensured, enabling it to maintain stable operation for a longer period even under frequent friction conditions, avoiding performance degradation due to wear. This improves the service life of the coal conveyor belt anti-coal-falling improvement structure for power plant production and reduces the frequency of maintenance and replacement.

[0021] Working principle: When it is necessary to collect coal ash adhering to the surface of the coal conveyor belt used in power plant production, the scraper 11 scrapes the surface of the conveyor belt 6 as it runs, causing the coal ash to detach from the surface of the conveyor belt 6 and escape into the air. At the same time, the blower 17 is started to run the suction pipe 18 to draw a vacuum to the lower inner side of the collection frame 13. Under the action of vacuum, the dust carrying the air enters the collection frame 13 and is filtered by the filter screen 16. Finally, the handle 14 is pulled to make the collection frame 13 detach from the support frame 1. In this way, the coal ash adhering to the coal conveyor belt used in power plant production can be automatically collected, improving the energy utilization rate.

[0022] 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.
