[0022] 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.

[0023] Please see Figure 3A dust suppression device for a ship unloader includes a frame 1. An adjustment mechanism is provided on the upper surface of the frame 1. The adjustment mechanism includes a sliding plate 9, a U-shaped frame 10, an L-shaped plate 11, a servo motor 12, a connecting shaft 13, a gear 14, a rack 15, and a receiving block 16. A rectangular groove 8 is formed on the upper surface of the frame 1. The outer surface of the bottom end of the sliding plate 9 is slidably connected to the inner wall of the rectangular groove 8. The bottom of the U-shaped frame 10 is fixedly installed to the upper surface of the sliding plate 9. The front of the L-shaped plate 11 is fixedly installed to the back of the U-shaped frame 10. The servo motor... The front of the machine 12 is fixedly connected to the back of the L-shaped plate 11. One end of the connecting shaft 13 is fixedly connected to one end of the output shaft of the servo motor 12. The inside of the gear 14 is fixedly installed with the outer surface of the connecting shaft 13. The upper surface of the rack 15 meshes with the outer surface of the gear 14. The top of the receiving block 16 is fixedly installed with the bottom of the rack 15, and the bottom of the receiving block 16 is fixedly installed with the top of the frame 1. The lower surface of the sliding plate 9 is in contact with the upper surface of the frame 1. A rotating block 27 is fixedly installed on the outer surface of the connecting shaft 13.

[0024] Specifically, after the servo motor 12 starts, it drives the connecting shaft 13 to rotate, which in turn causes the gear 14 to rotate. Since the gear 14 meshes with the rack 15, and the rack 15 is fixed to the frame 1 by the receiving block 16, the rotation of the gear 14 will drive the U-shaped frame 10 and the sliding plate 9 connected to it to slide horizontally in the rectangular groove 8, and through the action of the rotating block 27, the dust suppression angle position adjustment operation is realized.

[0025] Please see Figure 4 A lifting mechanism is provided on the outer surface of the connecting shaft 13. The lifting mechanism includes a gear 17, an extension plate 18, a fixed sleeve 19, a rack 20, and a fixed plate 21. The inside of the gear 17 is fixedly connected to the outer surface of one end of the connecting shaft 13. The back of the extension plate 18 is fixedly installed on the front of the sliding plate 9. The outer surface of the fixed sleeve 19 is fixedly installed on the inside of the extension plate 18. Both sides of the rack 20 are slidably connected to the inner wall of the fixed sleeve 19. The outer surface of the gear 17 meshes with the left side of the rack 20. The right side of the fixed plate 21 is fixedly connected to the top left side of the rack 20. A placement plate 22 is fixedly installed on the upper surface of the rotating block 27. Telescopic rods 23 are fixedly installed on both sides of the upper surface of the placement plate 22. A connecting frame 24 is fixedly installed at one end of the telescopic rod 23. The right side of the connecting frame 24 is fixedly connected to the left side of the fixed plate 21. A water cylinder 25 is fixedly installed on the back of the connecting frame 24. Multiple atomizing nozzles 26 are provided inside the water cylinder 25.

[0026] Specifically, when the connecting shaft 13 rotates, it drives the second gear 17 to rotate. The second gear 17 meshes with the second rack 20, which slides vertically under the constraint of the fixed sleeve block 19, thereby driving the fixed plate 21 to rise and fall, flexibly adjusting the height of the water cylinder 25 so that the atomizing nozzle 26 can be in the optimal dust suppression position, enhancing the dust suppression effect. The rotating block 27 and the placement plate 22 provide a stable support platform for the telescopic rod 23 and the water cylinder 25. Multiple sets of atomizing nozzles 26 are set inside the water cylinder 25, which can atomize water into fine water droplets. These fine water droplets can fully contact the dust particles in the air, causing the dust particles to be quickly moistened and settled, thereby achieving the purpose of efficient dust suppression.

[0027] Please see Figure 1 and Figure 2 The bottom of the frame 1 is equipped with two sets of moving wheels 2. A handrail 3 is fixedly installed on the right side of the upper surface of the frame 1. A limit screw 4 is connected to the internal thread of the frame 1. A water tank 5 is fixedly installed on the right side of the upper surface of the frame 1. A pump body 6 is fixedly connected to the water outlet on the left side of the water tank 5. A connecting hose 7 is fixedly connected to the water outlet of the pump body 6, and one end of the connecting hose 7 is fixedly installed to the inside of the water tank 25.

[0028] Specifically, two sets of moving wheels 2 are installed at the bottom of the frame 1, allowing the entire dust suppression device to move easily between different positions. The handle 3 is fixedly installed on the right side of the upper surface of the frame 1, providing a point of leverage for the operator. The operator can control the direction and speed of the equipment's movement by pushing the handle 3. After moving to a suitable working position, the limit screw 4 is rotated to make it contact the ground or other fixed objects and generate sufficient friction, thereby fixing the frame 1 in the current position. This prevents the equipment from moving due to external forces during dust suppression operations, ensuring that the dust suppression device can work stably and guarantee the dust suppression effect. The pump body 6 is installed at the left outlet of the water tank 5, which can draw water from the water tank 5 and pressurize and transport it. The connecting hose 7 has a certain degree of flexibility and bendability, which can stably transport the water pumped by the pump body 6 into the water tank 25 without affecting the movement and adjustment of the water tank 25.

[0029] Working principle: During use, the device is moved to the working position by the casters 2 at the bottom of the frame 1. The frame 1 is then fixed by the limit screw 4. After that, the servo motor 12 is started by the electrical connection of the external power source, which in turn drives the connecting shaft 13 to rotate the gear 14. Through the meshing with the rack 15, the sliding plate 9 is pushed to slide laterally along the rectangular groove 8, realizing the horizontal adjustment of the U-shaped frame 10. This can drive the water cylinder 25 and the atomizing nozzle 26 to change their positions synchronously, and also through the rotating block 27. The pump body 6 carries the water cylinder 25 and the atomizing nozzle 26, causing the angle of their positions to change. At the same time, while driving the servo motor 12, the gear 17 at the end of the connecting shaft 13 drives the rack 20 to move vertically within the fixed sleeve block 19. Through the linkage of the fixed plate 21 and the connecting frame 24 with the telescopic rod 23, the height of the water cylinder 25 and the atomizing nozzle 26 can be adjusted. The pump body 6 delivers water from the water tank 5 to the water cylinder 25 through the connecting hose 7, and finally forms a dust-suppressing water mist through the atomizing nozzle 26 to cover the unloading dust area.
