[0023] The present invention will be further described below with reference to the embodiments.

[0024] Example 1:

[0025] See also Figures 1-4 The adjusting assembly 7 includes a mounting frame 71 arranged on the upper surface of the base plate 1, a shock-absorbing spring 72 arranged on the inner wall of the mounting frame 71, and an elastic support block 73 arranged on the upper end of the shock-absorbing spring 72. The outer surface of the nozzle 4 is fixedly sleeved with a mounting ring 74. The outer surface of the mounting ring 74 contacts the inner wall of the elastic support block 73. The interior of the mounting frame 71 is rotatably connected with a threaded rod 75. The threaded rod 75 is symmetrically arranged in two groups. One end of the two groups of threaded rods 75 is connected to the internal thread of the mounting ring 74. The upper surface of the base plate 1 is hinged with an electric push rod 76. The telescopic end of the electric push rod 76 is hinged with a positioning ring A77. The inner wall of the positioning ring A77 is connected to the outer surface of the nozzle 4. The outer surface of the fan 5 is provided with The collar 78 and the upper surface of the mounting frame 71 are provided with a fixing column 711, and an elastic band 79 is sleeved between the collar 78 and the fixing column 711. The spray angle of the nozzle 4 is adjusted by the extension and contraction of the electric push rod 76. Since the mounting ring 74 on the surface of the nozzle 4 is in contact with the elastic support block 73 and the shock-absorbing spring 72, it can absorb a large amount of vibration generated during the operation, making the nozzle 4 work more stably, and the nozzle 4 is also rotatably connected to the inner wall of the mounting frame 71 through the threaded rod 75, so that the nozzle 4 does not hinder the adjustment of the spray angle, and further increases the stability of the connection. The fan 5 can also be pulled by the elastic band 79 and the fixing column 711, thereby ensuring the relative stability of the entire equipment.

[0026] Universal wheels 2 are provided at the bottom of the base plate 1. There are four groups of universal wheels 2. Brake pads are provided inside each group of universal wheels 2 to facilitate movement and to brake after the device moves to a specified position.

[0027] An armrest 3 is fixedly mounted on the upper surface of the base plate 1 to facilitate the operator to push the device to move.

[0028] The spray assembly 6 includes a water tank 61 arranged on the upper surface of the base plate 1, a connecting pipe 62 fixedly installed on one side of the water tank 61, and a water pump 63 arranged on one side of the connecting pipe 62. The bottom of the water pump 63 is connected to the upper surface of the base plate 1, and one end of the water pump 63 is provided with a telescopic hose A64, and one end of the telescopic hose A64 is provided with an annular pipe 65. The outer surface of the annular pipe 65 is connected to one side of the positioning ring A77, and the outer surface of the annular pipe 65 is provided with a telescopic hose B66. One end of the telescopic hose B66 is provided with an atomizing nozzle 67. The water pump 63 extracts the dust reduction water stored in the water tank 61 through the connecting pipe 62, and then transports it to the annular pipe 65 through the telescopic hose A64, and then reaches the atomizing nozzle 67 through the telescopic hose B66. The atomizing nozzle 67 atomizes the water and sprays it out to achieve dust reduction.

[0029] The inner wall of the nozzle 4 is provided with a placement ring 8, and a groove 81 is opened on one side of the placement ring 8. The inner wall of the groove 81 is hinged with a fixing belt 82, and one end of the fixing belt 82 is engaged with the inner wall of the groove 81. One end of the telescopic hose B66 passes through the interior of the nozzle 4, and the end thereof that passes through is located between the groove 81 and the fixing belt 82. One side of the atomizing nozzle 67 contacts one side of the fixing belt 82, and the telescopic hose B66 is fixed in the groove 81 by the fixing belt 82, so that the atomizing nozzle 67 remains stable in the nozzle 4, thereby ensuring the accuracy and effectiveness of dust reduction.

[0030] The inner wall of the nozzle 4 is provided with an anti-corrosion layer 9 , which is a component made of a ceramic coating and prevents the inner wall of the nozzle 4 from being corroded, thereby increasing the service life of the nozzle 4 .

[0031] Specifically, the device is pushed to the designated dust reduction point by the universal wheel 2 and the handrail 3, and the brake is applied by the brake pad inside the universal wheel 2 to prevent displacement, and then the spray angle of the nozzle 4 is adjusted by the extension and contraction of the electric push rod 76. Since the mounting ring 74 on the surface of the nozzle 4 is in contact with the elastic support block 73 and the shock-absorbing spring 72, it can absorb a large amount of vibration generated during the working process, making the nozzle 4 work more stably, and the nozzle 4 is also rotatably connected to the inner wall of the mounting frame 71 by the threaded rod 75, so that the nozzle 4 does not hinder the adjustment of the spray angle, and further increases the stability of the connection. The fan 5 can also be pulled by the elastic belt 79 and the fixing column 711, thereby ensuring the relative stability of the entire device, and then the water pump 6 is started. 3, so that it can extract the dust reduction water stored in the water tank 61 through the connecting pipe 62, and then transport it to the annular pipe 65 through the telescopic hose A64, and then reach the atomizing nozzle 67 through the telescopic hose B66. The atomizing nozzle 67 atomizes the water and sprays it out to achieve dust reduction. At the same time, since the telescopic hose B66 is fixed in the groove 81 by the fixing belt 82, the atomizing nozzle 67 remains stable in the nozzle 4, thereby ensuring the accuracy and effectiveness of dust reduction. Because the fan 5 is provided on one side of the nozzle 4, the spraying range of the water mist can be increased by the airflow generated by the fan 5. In addition, since the inner wall of the nozzle 4 is provided with an anti-corrosion layer 9 made of ceramic coating, the inner wall of the nozzle 4 can be prevented from being corroded, thereby increasing the service life of the nozzle 4.
