Description

Technical Field

[0001] This utility model belongs to the field of coal mine production technology, and in particular relates to a lifting dust suppression curtain for a coal conveyor belt. Background Technology

[0002] Coal conveyor belts are core equipment for achieving continuous and efficient transportation in coal mining, processing, and transportation processes. They are widely used in underground coal mines, surface coal washing plants, power plants, ports, and other scenarios, and are mainly used to transport coal from mining points, storage points, or processing points to target locations.

[0003] In coal conveyor belt systems, the lifting function of the dust suppression curtain is a key design feature for balancing dust control. The conveying capacity of the conveyor belt is adjusted according to production needs. When the conveying capacity is large, the coal accumulates high on the surface of the conveyor belt. If the curtain is too low, it will rub against the coal. To address this, a lifting dust suppression curtain for coal conveyor belts has been designed. This device, through its adjustable structure, allows the curtain in front of the sealed dust suppression trough to rise and fall appropriately, thereby preventing some coal from rolling off the coal conveyor due to friction between the coal and the rubber curtain.

It includes a sealed dust suppression trough 2 bolted to the top of a coal block conveyor 1. A front support plate 3 is bolted to the front side of the sealed dust suppression trough 2. A support rod 4 is slidably connected to the inner cavity of the front support plate 3. Through slots are provided on both the left and right sides of the support rod 4. Circular plates 5 are slidably connected to the inner cavities of both through slots. A spring 6 is welded between the circular plate 5 and the inner cavity of the support rod 4. A columnar head 7 is welded to the end of the circular plate 5 opposite to the spring 6. Three through holes are provided on both the left and right sides of the front support plate 3. The surface of the columnar head 7 is slidably connected to the inner cavity of the through hole. A rubber curtain 8 is fixedly connected to the bottom of the support rod 4. A round rod 9 is slidably connected to the inner cavity of the through hole. Three extension tubes 10 are welded to both the left and right sides of the front support plate 3. The inner cavity of the extension tube 10 is connected to the through hole. The surface of the round rod 9 is slidably connected to the inner cavity of the extension tube 10. A rubber pad 11 is fixedly connected to the end of the round rod 9 opposite to the columnar head 7. By setting the rubber pad 11, the contact surface between the worker's fingers and the round rod 9 can be made softer, and the worker's experience of pressing the round rod 9 can be more comfortable.

[0024] Example 2:

[0025] Figure 1-4 This invention illustrates a lifting dust suppression curtain for a coal conveyor belt according to an embodiment of the present invention. It includes a sealed dust suppression trough 2 bolted to the top of a coal block conveyor 1. A front support plate 3 is bolted to the front side of the sealed dust suppression trough 2. A support rod 4 is slidably connected to the inner cavity of the front support plate 3. Through slots are provided on both the left and right sides of the support rod 4. Circular plates 5 are slidably connected to the inner cavities of both through slots. A spring 6 is welded between the circular plate 5 and the inner cavity of the support rod 4. A columnar head 7 is welded to the end of the circular plate 5 opposite to the spring 6. The front support... Three through holes are provided on both the left and right sides of the support plate 3. The surface of the column head 7 is slidably connected to the inner cavity of the through hole. A rubber curtain 8 is fixedly connected to the bottom of the support rod 4. Screw holes 12 are provided on the surfaces of the front support plate 3 and the support rod 4. Bolts 13 are threadedly connected to the inner cavity of the screw holes 12. Washers 14 are slidably connected to the surface of the bolts 13. By setting the washers 14, the bolts 13 and the front support plate 3 can be spaced apart, so that the bolts 13 can avoid damage to the surface of the support rod 4 during rotation.

[0026] Working principle: When using this utility model, the user, with the cooperation of the staff, has one person press down on the two round rods 9 in opposite directions, which in turn pushes the cylindrical head 7 to slide into the inner cavity of the through groove, thereby ending the limiting force between the support rod 4 and the front support plate 3. At this time, the other person supports the support rod 4 and pulls the support rod 4 upward to slide it. Then, when the support rod 4 slides to the position of another through hole, the rebound force of the spring 6 causes the cylindrical head 7 to reset and slide into the inner cavity of the through hole, thereby limiting the support rod 4 again. Then, the bolts 13 are used to connect and fix the support rod 4 and the front support plate 3, thereby achieving a better fixing effect for the support rod 4. At the same time, the position of the rubber curtain 8 is raised, which can prevent some coal from rolling off the coal conveyor 1 due to friction between the coal and the rubber curtain 8.

[0027] In summary: the lifting dust suppression curtain of this coal conveyor belt slides by pulling the support rod 4 upwards, and then the rebound force of the spring 6 causes the column head 7 to slide into the inner cavity of the through hole, thereby limiting the support rod 4 again and raising the position of the rubber curtain 8. This can prevent some coal blocks from rolling off the coal conveyor 1 due to friction between the coal blocks and the rubber curtain 8.
