Several evenly distributed rollers 9 are located at the bottom of the movable base 1. Anti-slip components are located on both sides of the movable base 1. The height adjustment assembly includes an adjustment groove 11 on one side of the lifting column 2, a lead screw 12 within the adjustment groove 11, and a movable block 13 matching the adjustment groove 11 fitted onto the outer wall of the lead screw 12. One side of the movable block 13 extends outside the adjustment groove 11 and connects to the mounting ring 3. Lead screw 12 is connected to lifting column 2 via bearing. The top end of lead screw 12 extends outside lifting column 2 and is connected to the drive end of servo motor 14. The moving block 13 has a threaded hole that matches lead screw 12. The top of water tank 6 is provided with a matching tank cover 15, and the top of tank cover 15 has symmetrically arranged handles. During dust suppression, the mounting ring 3 is moved above the material discharge end of the stacker. First, the servo motor 14 is started to drive the lead screw 12 to rotate. The lead screw 12 drives the moving block 13 to move upward. The moving block 13 drives the annular water pipe 4 to move upward through the mounting ring 3 until it moves above the material discharge end of the stacker. Then, the conveying pump 8 is started to convey water from the water tank 6 to the annular water pipe 4 through the conveying hose 7. The water entering the annular water pipe 4 is sprayed downward through the spray nozzle 10 to suppress the dust generated during the stacking process. By setting the height adjustment component, the height of the annular water pipe can be adjusted according to the actual distance between the material discharge end of the stacker and the ground, so that the spray nozzle on the annular water pipe can better suppress the dust generated during the stacking process. Example

[0026] like Figure 1-5As shown, the device includes a movable base 1, a lifting column 2 on one side of the top of the movable base 1, and a mounting ring 3 on one side of the lifting column 2. The mounting ring 3 is connected to the lifting column 2 via a height adjustment component. An annular water pipe 4 is installed in the mounting ring 3 and is connected to the mounting ring 3 via a connecting block 5. Several evenly distributed spray nozzles 10 are provided at the bottom of the annular water pipe 4. A water tank 6 is provided on the side of the top of the movable base 1 away from the lifting column 2. The water tank 6 is connected to the annular water pipe 4 via a delivery hose 7. A delivery pump 8 is provided on the delivery hose 7. Several evenly distributed rollers 9 are provided at the bottom of the movable base 1. Anti-slip components are provided on both sides of the movable base 1. The anti-slip components include symmetrically arranged mounting seats 16 on both sides of the movable base 1. A symmetrically arranged adjustment groove 2 17 is opened on the side of the mounting seat 16 away from the movable base 1. An installation plate 18 is provided in the adjustment groove 2 17. A servo motor 2 19 is provided at the bottom of the mounting plate 18. A lead screw 20 is provided at the drive end of the servo motor 2 19. The bottom end of the lead screw 20 extends to the outside of the mounting seat 16 and is connected to the drill bit 21. The mounting base 16 has symmetrically arranged guide blocks 22 on both sides, and the mounting base 16 has guide grooves 23 that match the guide blocks 22. The mounting base 16 also has threaded holes that match the lead screw 20. When it is necessary to move the moving base 1, the moving base 1 is directly pushed to the appropriate position via the rollers 9. Then, the servo motor 19 is started to drive the lead screw 20 to rotate. Since the lead screw 20 is threadedly connected to the mounting base 16, when the lead screw 20 rotates, it simultaneously drives the drill bit 21 to rotate and move downwards until the drill bit 21 drills into the soil and limits and fixes the moving base 1. The rollers and anti-slip components facilitate the movement of the dust suppression device, making it more flexible and convenient to use. The anti-slip components can limit and fix the dust suppression device after it is moved to the appropriate position, preventing the dust suppression device from moving automatically during the dust suppression process.

[0027] In practical applications, during dust suppression, the mounting ring 3 is moved above the material discharge end of the stacker. First, the servo motor 14 is started, driving the lead screw 12 to rotate. The lead screw 12 drives the moving block 13 to move upward. The moving block 13, through the mounting ring 3, drives the annular water pipe 4 to move upward until it reaches above the material discharge end of the stacker. Then, the conveying pump 8 is started, and water from the water tank 6 is conveyed to the annular water pipe 4 through the conveying hose 7. The water entering the annular water pipe 4 is sprayed downward through the spray nozzle 10 to suppress the dust generated during the stacking process. By setting a height adjustment component, the height of the annular water pipe can be adjusted according to the actual distance between the material discharge end of the stacker and the ground, so that the water on the annular water pipe... The spray nozzle can better suppress dust generated during the material stacking process. When it is necessary to move the moving base 1, simply push the moving base 1 to the appropriate position via the roller 9. Then, start the servo motor 19 to drive the lead screw 20 to rotate. Since the lead screw 20 is threadedly connected to the mounting base 16, when the lead screw 20 rotates, it simultaneously drives the drill bit 21 to rotate and move downwards until the drill bit 21 drills into the soil and limits and fixes the moving base 1. The rollers and anti-slip components make it easy to move the dust suppression device, making it more flexible and convenient to use. The anti-slip components can limit and fix the dust suppression device after it is moved to the appropriate position, preventing the dust suppression device from moving automatically during the dust suppression process.

[0028] In summary, by means of the above-mentioned technical solution of this utility model, the height of the annular water pipe can be adjusted according to the actual distance between the material discharge end of the stacker and the ground by setting a height adjustment component, so that the spray nozzles on the annular water pipe can better suppress dust generated during the material stacking process. The dust suppression device can be moved easily by setting rollers and anti-slip components, making it more flexible and convenient to use. The anti-slip components can limit and fix the dust suppression device after it is moved to a suitable position, preventing the dust suppression device from moving automatically during the dust suppression process.
