[0028] refer to Figure 4 The transverse movement mechanism 8 includes a fixed frame 81, which is fixedly installed on the top of the support rod 74. A third motor 85 is fixedly installed on the inner side of the fixed frame 81. The output end of the third motor 85 passes through the fixed frame 81 and is fixedly installed with a turntable 83. A top rail 84 is fixedly installed on the top of the turntable 83. A second motor 82 is fixedly installed on one end of the top rail 84. The output end of the second motor 82 passes through the top rail 84 and is fixedly installed with a second screw rod 86. The outer surface of the second screw rod 86 is threadedly connected to a movable block 87. The top of the movable block 87 is fixedly connected to the bottom of the positioning mechanism 9. The fixed frame 81 is firmly installed on the top of the support rod 74 as the supporting basis of the entire transverse movement mechanism 8. On the inner side of the fixed frame 81, the third motor 85 passes through the fixed frame 81 and is fixedly installed with a turntable 83. A top rail 84 is fixedly installed on the top of the turntable 83. A second motor 82 is fixedly installed on one end of the top rail 84. A second screw rod 86 is fixedly installed on the output end of the second motor 82. The motor 85 is fixedly installed and drives the turntable 83 to rotate through its output end. The turntable 83 is located on the fixed frame 81, and a top rail 84 is fixedly installed on the top of the turntable 83 to provide a track for the movement of the spray nozzle 10. At one end of the top rail 84, the second motor 82 is fixedly installed and connected to the second screw rod 86 through its output end. When the second motor 82 is running, it drives the second screw rod 86 to rotate. Since the movable block 87 is connected to the outer surface of the second screw rod 86 by a thread, when the second screw rod 86 rotates, the movable block 87 moves linearly along the direction of the screw rod. This design enables the spray nozzle 10 to achieve precise displacement in the horizontal direction, thereby achieving precise spraying at different positions.

[0029] refer to Figure 1-Figure 4 The internal cross-sectional shapes of the guide rail 71 and the top rail 84 are both set to a convex shape, and the overall cross-sectional shapes of the slider 73 and the movable block 87 are also set to a convex shape. The convex cross-sectional shape ensures that the slider 73 and the movable block 87 can slide stably inside the guide rail 71 and the top rail 84. The convex structure can prevent the slider 73 or the movable block 87 from lateral displacement or shaking during movement, thereby ensuring that they slide accurately and smoothly along a predetermined path. Secondly, the design of the convex cross-sectional shape also increases the contact area between the slider 73 and the guide rail 71, and the movable block 87 and the top rail 84. This design not only improves the friction of the sliding surface and makes the sliding more stable, but also enhances the load-bearing capacity and durability of the entire mechanism. During the operation of the lifting mechanism 7 and the transverse movement mechanism 8, this convex cross-sectional shape design can effectively prevent the slider 73 or the movable block 87 from falling off or dislocating due to vibration or external force impact.

[0030] refer to Figure 4The positioning mechanism 9 includes a concave seat 91, which is fixedly mounted on the top of the movable block 87. The upper ends of both sides of the concave seat 91 are threadedly connected with threaded rods 92. The ends of the threaded rods 92 penetrate the concave seat 91 and are rotatably connected with clamping plates 93. The spray nozzle 10 is clamped and mounted on the inner side of the concave seat 91 by the clamping plates 93. The concave seat 91 is fixedly mounted on the top of the movable block 87, providing a stable mounting base for the spray nozzle 10. The design of the concave seat 91 enables the spray nozzle 10 to be easily placed inside it for easy clamping and fixing. In order to clamp and fix the spray nozzle 10, the upper ends of both sides of the concave seat 91 are threadedly connected with threaded rods 92. The design of the threaded rods 92 allows the user to adjust its position by rotation, thereby driving the movement of the clamping plate 93. When the rotation When the threaded rod 92 is moved, due to the action of the thread, the threaded rod 92 will move up and down along the threaded hole of the concave seat 91, and the end of the threaded rod 92 passes through the concave seat 91 and is rotatably connected to the clamping plate 93. This design allows the clamping plate 93 to move accordingly with the up and down movement of the threaded rod 92. When the threaded rod 92 moves upward, the clamping plate 93 will move inward to clamp the spray nozzle 10; when the threaded rod 92 moves downward, the clamping plate 93 will move outward to release the clamping of the spray nozzle 10. Through this design, the user can easily install and remove the spray nozzle 10, and can also adjust the position of the spray nozzle 10 as needed. This positioning mechanism 9 not only improves the flexibility and applicability of the device, but also ensures the stability and reliability of the spray nozzle 10 during operation.

[0031] refer to Figure 4 The outer ends of the threaded rods 92 are fixedly connected with adjusting knob handles 94, and the outer lower ends of the clamping plates 93 are fixedly installed with support shafts 95, and the ends of the support shafts 95 pass through the concave seat 91. The design of the adjusting knob handles 94 enables the user to rotate the threaded rods 92 more easily. By rotating the adjusting knob handles 94, the user can conveniently adjust the position of the threaded rods 92, and then control the opening and closing degree of the clamping plates 93 to adapt to spray nozzles 10 of different sizes. This design not only improves the convenience of operation, but also ensures the uniform distribution of the clamping force, and avoids damage to the spray nozzles 10 caused by uneven clamping force. At the same time, the support shaft 95 design at the lower end of the outer side of the clamping plates 93 further enhances the stability and reliability of the clamping plates 93. The support shaft 95 passes through the concave seat 91, providing a fixed fulcrum for the clamping plates 93, making the clamping plates 93 more stable when clamping the spray nozzles 10. This design not only improves the clamping effect, but also prolongs the service life of the clamping plates 93 and the concave seat 91.

[0032] Principle and advantages of use: By setting the lifting mechanism 7, the device can be operated by starting the first motor 75 during use, and the first motor 75 is used to drive the first screw rod 72 inside the guide rail 71 to rotate. The first screw rod 72 rotates to assist in driving the slider 73 to slide inside the guide rail 71, and the slider 73 slides up and down to assist in driving the support rod 74 to move up and down. At this time, the height of the spray nozzle 10 can be flexibly adjusted. By adjusting the height of the spray nozzle 10, it can be adapted to spray and dust reduction at different angles. During this period, the water pump 5 is started to operate. The water pump 5 can assist in pumping the water in the water tank 2 through the connecting pipe 6. The water is transported to the spray nozzle 10 through the hose 11. At this time, the atomized water vapor can be discharged into the mine through the spray nozzle 10, which can make it have better spray dust reduction performance. In addition, the walking wheel 12 is set to cooperate with the armrest 14. When the device needs to be moved, the walking wheel 12 can be dragged to roll by pulling the armrest 14, so that the device as a whole is easy to flexibly adjust the device.

[0033] By arranging the lateral movement mechanism 8 and the positioning mechanism 9 to cooperate, the spray nozzle 10 can be placed inside the concave seat 91 during use of the device. By twisting the adjusting knob handle 94 to drive the threaded rod 92 to rotate, the clamping plate 93 can be driven to move inward by rotating the threaded inner rod. The clamping plate 93 can move inward to contact the spray nozzle 10, and the installation can be completed by clamping the spray nozzle 10. When maintenance is required during use, it only needs to loosen the adjusting knob handle 94 to drive the threaded rod 92 to move outward for quick disassembly. During use, the third motor can be started to 85 is running, the third motor 85 can be used to drive the turntable 83 to rotate, and the rotation of the turntable 83 can drive the top rail 84 to rotate and move, and the second motor 82 can be started to auxiliary drive the second screw rod 86 to rotate, and the rotation of the second screw rod 86 can drive the movable block 87 to move. At this time, the displacement of the movable block 87 can drive the spray nozzle 10 to rotate during the lateral displacement, so that the spray nozzle 10 can be displaced laterally to radiate the spray to a larger area. At the same time, the rotation of the spray nozzle 10 can adjust the angle of the radiated spray, so that the device can have a strong adaptability.
