[0042] like Figure 8 and Fig.12 As shown, the water guide assembly includes a third connecting pipe 48 sleeved between the dust suppression box 3 and the filter box 4, one end of the third connecting pipe 48 is fixedly connected to the input end of the water pump 23, and the other end of the third connecting pipe 48 is installed with a water suction nozzle 27, and a guide plate 26 is installed inside the filter box 4, and a water suction groove 28 is opened at the center of the guide plate 26, and the water suction nozzle 27 is engaged with the water suction groove 28. When there is little water inside the filter box 4, a small amount of water enters the inside of the water suction groove 28 through the guide plate 26, which is convenient for sucking out the water inside the water suction groove 28 through the water suction nozzle 27, avoiding the phenomenon of empty suction of the water suction nozzle 27, which is conducive to the maintenance of the water guide assembly.

[0043] like Figure 3 and Fig. 9 As shown, the filter assembly includes a second mounting groove 10 opened on the top of the filter box 4, the second mounting groove 10 is internally slidingly sleeved with a second filter screen 29, a sealing plate 12 is installed on the top of the second filter screen 29, a pull ring 11 is installed on the top of the sealing plate 12, a first limiting plate 30 is installed on the inner side of the filter box 4, a limiting groove 31 is opened on the outside of the first limiting plate 30, the outer side of the second filter screen 29 is slidably connected to the limiting groove 31, and the impurities in the water of the filter box 4 are filtered through the second filter screen 29 arranged inside the filter box 4 to prevent the particles in the water from being blocked in the third connecting pipe 48, the second connecting pipe 22 and the dust suppression nozzle 7, so as to facilitate the maintenance of the equipment in the later stage.

[0044] like Figure 1 and Figure 8 As shown, a connecting plate 41 is installed on the outside of the dust reduction box 3, and a collecting bucket 39 is obliquely connected to the top of the connecting plate 41. A fourth connecting pipe 49 is fixedly sleeved inside one side of the collecting bucket 39, and the other end of the fourth connecting pipe 49 is sleeved in the filter box 4. A water guide plate 50 is provided on the top of the collecting bucket 39. The dripping water sprayed from the dust reduction nozzle 7 enters the interior of the collecting bucket 39 through the guide plate 26, and flows into the interior of the filter box 4 through the fourth connecting pipe 49, and is filtered through the second filter screen 29 before use.

[0045] Working principle:

[0046] When in use, the trolley bottom plate 1 is pushed to the position where dust reduction is required by manpower, and then the interior of the filter box 4 is filled with water, and the impurities in the water of the filter box 4 are filtered through the second filter screen 29 arranged inside the filter box 4 to prevent the particles in the water from being blocked in the third connecting pipe 48, the second connecting pipe 22 and the dust reduction nozzle 7, so as to facilitate the maintenance of the equipment in the later stage. When the second filter screen 29 needs to be replaced, the pull ring 11 can be pulled to make the pull ring 11 drive the second filter screen 29 at the bottom of the sealing plate 12 to separate the second filter screen 29 from the first limiting plate 30, and then the second filter screen 29 is taken out. After cleaning the second filter screen 29, the second filter screen 29 is inserted into the interior of the second installation groove 10, and the two sides of the second filter screen 29 are moved along the limiting groove 31. When the bottom of the second filter screen 29 contacts the bottom of the filter box 4, the sealing plate 12 on the top of the second filter screen 29 is fixed to the second mounting groove 10 to prevent dust from entering the interior of the filter box 4. When the water pump 23 is connected to an external power supply to work, the water inside the filter box 4 is input into the second connecting pipe 22 and the first connecting pipe 5 through the third connecting pipe 48, and the water is sprayed out through the dust reduction nozzle 7. When there is less water inside the filter box 4, a small amount of water enters the water suction groove 28 through the guide plate 26, so that the water inside the water suction groove 28 can be sucked out through the water suction nozzle 27, thereby avoiding the phenomenon of empty suction by the water suction nozzle 27, which is beneficial to the maintenance of the water guide component, and dust is removed at the location with more dust through the dust reduction nozzle 7. The first filter screen 9 on the outside of the head 7 can block dust and prevent dust from entering the inside of the dust suppression nozzle 7 to avoid affecting the dust suppression nozzle 7. When the first filter screen 9 needs to be disassembled, the connecting rod 47 is pulled in sequence, and then during the pulling process, the second spring 43 is squeezed with the inside of the disassembly part 8 to separate the slot plate 42 from the third connecting block 33, and the slot plate 42 is rotated 180 degrees. At the same time, under the reaction force of the second spring 43, the slot plate 42 is separated from the third connecting block 33 through the slot 32, and the first filter screen 9 on the dust suppression nozzle 7 is taken out, and then the surface of the first filter screen 9 is cleaned, and then the first filter screen 9 is aligned with the installation position of the outside of the dust suppression nozzle 7 during installation, and then the connecting rod 47 is pulled in sequence to make the connecting rod 47 The second spring 43 on the outside is squeezed and contracted, and then the connecting rod 47 is rotated 180 degrees, and then the connecting rod 47 is loosened, and then the slot plate 42 is contacted with the outside of the third connecting block 33 under the reaction force of the second spring 43, and the first filter screen 9 is fixed to the outside of the dust suppression nozzle 7. When it is necessary to open the box door 38 to inspect the water pump 23 inside the dust suppression box 3, the card plate 36 is rotated clockwise to separate the card plate 36 from the connecting slot 34, and then the box door 38 can be opened. After the inspection is completed, the box door 38 is closed, and the card plate 36 is rotated counterclockwise to make the card plate 36 contact with the connecting slot 34, and then it is fixed. At the same time, when the box door 38 contacts the elastic member 44 inside the filter box 4, the door is pressed to generate a reaction force.Then, the connecting groove 34 is further tightened by the clamping plate 36. When the box door 38 is damaged and needs to be replaced, the adjusting disk 18 is rotated clockwise to move the adjusting disk 18 upward inside the threaded matching block 16, thereby separating the screw 17 from the threaded matching block 16, and then the box door 38 is pulled upward to separate the mounting ring 20 from the first shaft 21, and the box door 38 is further taken out. When installing, it is only necessary to sleeve the mounting ring 20 on the outside of the first shaft 21, and then rotate the screw 17 clockwise through the adjusting disk 18. The screw rod 17 is in contact with the top of the first shaft rod 21, so as to facilitate the fixing of the box door 38. When the water inside the filter box 4 decreases, the water flows into the water suction groove 28 through the guide plate 26, and the water is sucked into the third connecting pipe 48 through the water suction nozzle 27. Even if the water inside the filter box 4 is less, it can work normally. At the same time, the water sprayed by the dust suppression nozzle 7 enters the collection bucket 39 through the guide plate 26, and flows into the filter box 4 through the fourth connecting pipe 49, and is filtered by the second filter screen 29 before use.
