A second conduit 34 is rotatably installed on the top of the first conduit 33, and an atomizing nozzle 35 is provided at the end of the second conduit 34. When it is necessary to drive the device to spray and reduce dust at the construction site, it is only necessary to turn on the water pump 32. When the water pump 32 is turned on, the water in the water tank 31 will be automatically pumped into the first conduit 33, and then the water will be transported to the second conduit 34 through the diversion of the first conduit 33, and finally atomized and sprayed out through the atomizing nozzle 35.

[0025] The middle position of the first conduit 33 is set as a telescopic tube structure, and the second conduit 34 is divided into two parts, the upper and lower parts, and the second conduit 34 located in the upper part is set as an inclined structure; the middle position of the first conduit 33 here is set as a telescopic tube structure. In order to adapt to the needs of the up and down displacement of the water tank 31 described below, the second conduit 34 located in the upper part is set as an inclined structure to facilitate its subsequent rotation angle for spraying.

[0026] Two groups of limiting T-shaped blocks 41 are symmetrically arranged on the side outer wall of the water tank 31 at the bottom position, and two groups of limiting T-shaped grooves 42 are symmetrically opened on the side inner wall of the protective outer box 2. The limiting T-shaped blocks 41 and the limiting T-shaped grooves 42 are symmetrically installed. Support springs 43 are symmetrically connected with equal intervals between the bottom outer wall of the water tank 31 and the bottom inner wall of the protective outer box 2; when the water tank 31 moves up and down, it will automatically drive the limiting T-shaped blocks 41 to slide inside the limiting T-shaped grooves 42. At the same time, the setting of the limiting T-shaped blocks 41 and the limiting T-shaped grooves 42 has the effect of limiting support for the movement of the water tank 31, and the setting of the support springs 43 here has the effect of auxiliary support for the water tank 31.

[0027] The automatic water storage mechanism 5 includes a positioning support block 51 and a limit rack 52. The side outer wall of the water storage tank 31 at the bottom position is provided with a positioning support block 51, and the side outer wall of the positioning support block 51 is provided with a limit rack 52. The limit rack 52 is arranged on the outside of the protective outer box 2. The side outer wall of the protective outer box 2 at the top position is provided with a positioning support plate 53.

The positioning gear 55 and the limiting rack 52 are meshedly connected, the end of the auxiliary support shaft 54 ​​is connected to the side outer wall of the valve stem 56, and the side outer wall of the protective outer box 2 at the top position is connected and installed with a water injection pipe 57, a valve is arranged inside the water injection pipe 57, and the valve stem 56 is connected to the valve; when the water storage inside the water storage tank 31 decreases, the support spring 43 is squeezed by the water storage tank 31 The force becomes smaller and the water storage tank 31 will automatically move upward, and then the water storage tank 31 moves upward. When the limit rack 52 is engaged with the limit gear 55 during movement, the rotation of the limit gear 55 will automatically drive the auxiliary support shaft 54 ​​to rotate and then drive the valve stem 56 to rotate. Then, the rotation of the valve stem 56 will automatically open the valve inside the water injection pipe 57. It is noted here that the water injection pipe 57 needs an external water source. Then, through the diversion of the water injection pipe 57, the external water source will be automatically injected into the water tank 31 to replenish it. Then, the overall gravity of the water tank 31 increases, and the support spring 43 automatically contracts under the extrusion effect, which will automatically drive the water tank 31 to move downward. The principle is the same as above. At this time, the valve stem 56 will automatically close the valve when it rotates in the opposite direction. Then, the effect of automatic water storage is achieved through the above-mentioned setting.

[0028] The spray control mechanism 6 includes a transmission gear ring 61, a transmission gear 62, a control shaft 63, a control motor 64 and a positioning support frame 65. The transmission gear ring 61 is arranged outside the first conduit 33, and the side of the transmission gear ring 61 is meshed with the transmission gear 62. The transmission gear ring 61 and the transmission gear 62 are both rotatably mounted on the top outer wall of the protective outer box 2. The top outer wall of the transmission gear 62 is provided with a control shaft 63, and the top outer wall of the control shaft 63 is connected to the control motor 64. The bottom outer wall of the control motor 64 is connected to the top outer wall of the positioning support frame 65. The positioning support frame 65 is arranged in an inverted "L" shape, and the positioning support frame 65 is connected to the top outer wall of the protective outer box 2. The control motor 64 A protective cover 66 is provided on the outside, and the protective cover 66 is connected to the top outer wall of the protective outer box 2, and the transmission gear ring 61 and the transmission gear 62 are both located inside the protective cover 66; when it is necessary to control the atomizing nozzle 35 to rotate and spray, it is necessary to first turn on the control motor 64. The setting of the positioning support frame 65 here plays an auxiliary supporting effect on the control motor 64. When the control motor 64 is turned on, it will automatically drive the control shaft 63 to rotate and then drive the transmission gear 62 to rotate. Then, the rotation of the transmission gear 62 will automatically drive the transmission gear ring 61 to rotate and then drive the second conduit 34 to rotate. Subsequently, the rotation of the second conduit 34 will automatically drive the atomizing nozzle 35 to rotate, thereby achieving the effect of rotating spraying.

[0029] When the utility model is in use, when it is necessary to drive the device to spray dust at the construction site, it is only necessary to turn on the water pump 32. When the water pump 32 is turned on, the water stored in the water tank 31 will be automatically pumped into the first conduit 33, and then the water will be transported to the second conduit 34 through the diversion of the first conduit 33, and finally sprayed out through the atomizing nozzle 35 in the form of atomizer. When the water stored in the water tank 31 decreases, the support spring 43 will automatically push the water tank 31 when the squeezing force of the water tank 31 becomes smaller. The water tank 31 moves upward, and the upward movement of the water tank 31 will automatically drive the limiting T-shaped block 41 to slide inside the limiting T-shaped groove 42. At the same time, the setting of the limiting T-shaped block 41 and the limiting T-shaped groove 42 plays a limiting support effect on the movement of the water tank 31. The upward movement of the water tank 31 will automatically drive the positioning support block 51 to move and then drive the limiting rack 52 to move upward. When the limiting rack 52 is engaged with the limiting gear 55 during the movement, the rotation of the limiting gear 55 will automatically drive the auxiliary support shaft 54 ​​to rotate. Then the valve stem 56 is driven to rotate, and then the rotation of the valve stem 56 will automatically open the valve inside the water injection pipe 57. It is noted here that the water injection pipe 57 needs an external water source. Then, through the diversion of the water injection pipe 57, the external water source will be automatically injected into the water storage tank 31, and then the overall gravity of the water storage tank 31 increases, and the support spring 43 automatically contracts under the extrusion effect, which will automatically drive the water storage tank 31 to move downward. The principle is the same as above. At this time, the valve stem 56 rotates in the opposite direction to automatically close the valve, and then the above-mentioned setting achieves the effect of automatic water storage; when it is necessary to control the atomizing nozzle 35 to rotate and spray, the control motor 64 needs to be turned on at this time. The setting of the positioning support frame 65 here plays an auxiliary supporting effect on the control motor 64. When the control motor 64 is turned on, it will automatically drive the control shaft 63 to rotate and then drive the transmission gear 62 to rotate. Then, the rotation of the transmission gear 62 will automatically drive the transmission gear ring 61 to rotate and then drive the second conduit 34 to rotate. Then, the rotation of the second conduit 34 will automatically drive the atomizing nozzle 35 to rotate, thereby achieving the effect of rotating spraying.

[0030] It is noted here that the above-mentioned control motor 64 can be powered by existing technology, whether it is powered by a power supply unit or an external wire, which belongs to the existing conventional operating technical means and will not be described in detail here.

[0031] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
