[0021] To make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other arbitrarily without conflict.

[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 The embodiment of the present invention is shown in the figure, which discloses a construction site dust reduction device, including a support frame 1, and self-locking casters 2 are respectively arranged at the four corners of the bottom of the support frame 1 to facilitate the movement of the support frame 1 by the staff. A support pipe 3 is vertically arranged on the support frame 1, and the support pipe 3 is rotatably connected with the support frame 1 through a bearing. A support seat 4 is arranged on the top of the support pipe 3, and an atomizing nozzle 5 is arranged on the support seat 4, and the top of the support pipe 3 is connected to the water inlet end of the atomizing nozzle 5 through a water pipe 6.

[0023] Reference Figure 1 , Figure 2 A water inlet joint 7 is provided at the bottom of the support tube 3, and the water inlet joint 7 is rotatably connected to the support tube 3 through a sealed bearing. A water inlet pipe 8 is connected to the water inlet joint 7, and the water inlet pipe 8 is used to connect to an external water supply pipeline. At the same time, a control member 9 for controlling the rotation of the support tube 3 is provided on the support frame 1.

[0024] The clean water supplied by the external water supply pipeline enters the water inlet joint 7, the support pipe 3 and the water pipe 6 in sequence through the water inlet pipe 8, and then the clean water is sprayed out after being atomized by the atomizing nozzle 5. At the same time, the support pipe 3 is controlled by the control component 9 to drive the support base 4 and the atomizing nozzle 5 to rotate, so as to adjust the spraying angle of the atomizing nozzle 5, increase the spraying area, and thus improve the dust reduction effect.

[0025] Reference Figure 1 , Figure 2 , Figure 3The control member 9 includes a control box 91 fixed on the support frame 1, the support pipe 3 passes through the control box 91, and is rotatably connected to the control box 91 through a sealed bearing. At the same time, the fixed sleeve of the support pipe 3 located in the control box 91 is provided with a control impeller 92. A water supply pipe 93 is connected to one side of the control box 91, and a water outlet pipe 94 is connected to the other side. The water supply pipe 93 is connected to the water inlet pipe 8, and the water outlet pipe 94 is connected to the water inlet joint 7. The water supply pipe 93 and the water outlet pipe 94 are arranged in a staggered manner, and the clean water sprayed from the water supply pipe 93 can impact the blades of the control impeller 92, so that the control impeller 92 drives the support pipe 3 to rotate.

[0026] When clean water flows through the water inlet pipe 8, part of the clean water enters the control box 91 through the water supply pipe 93. At this time, the clean water sprayed from the water supply pipe 93 can impact the blades of the control impeller 92, so that the control impeller 92 drives the support pipe 3 and the atomizing nozzle 5 and other components to rotate, and then the clean water enters the support pipe 3 through the water outlet pipe 94 and is supplied to the atomizing nozzle 5. This design enables the atomizing nozzle 5 to rotate automatically without the need for the staff to manually adjust the direction of the atomizing nozzle 5, thereby realizing the automatic adjustment of the spray angle of the atomizing nozzle 5 and reducing the burden on the staff.

[0027] Reference Figure 1 , Figure 2 , Figure 3 The water supply pipe 93 is provided with a solenoid valve 10, and the solenoid valve 10 is used to control the on and off of the water supply pipe 93. At the same time, the support frame 1 is provided with a limiter 11 for limiting the rotation of the support pipe 3. The limiter 11 includes a limiter gear 111 fixedly sleeved on the support pipe 3, and a limiter rack 112 is horizontally slidably connected to the support frame 1. The support frame 1 is provided with a hydraulic cylinder 113 for controlling the horizontal sliding of the limiter rack 112, so that the limiter rack 112 can be engaged or separated with the limiter gear 111.

[0028] When the staff needs to spray water mist in a specific direction, the rotating atomizing nozzle 5 drives the supporting tube 3 and other components to rotate until the atomizing nozzle 5 reaches the required spraying angle. Then, the hydraulic cylinder 113 controls the limit rack 112 to move toward the limit gear 111 until the limit rack 112 is engaged with the limit gear 111 to lock the supporting tube 3. Then, the solenoid valve 10 is controlled to close so that clean water cannot enter the control box 91 through the water supply pipe 93. At this time, the atomizing nozzle 5 can spray water mist in a specific direction.

[0029] Reference Figure 1 , Figure 3The water pipe 6 is a corrugated pipe, that is, the water pipe 6 can be bent, and two hinge shafts 12 are symmetrically fixedly connected to the atomizing nozzle 5, and the two hinge shafts 12 are respectively hinged to the support base 4. At the same time, an adjusting member 13 is provided on the water inlet joint 7 and the support pipe 3, and the adjusting member 13 is used to adjust the water inlet flow of the support pipe 3, so that the atomizing nozzle 5 can swing in the vertical direction under the action of water pressure.

[0030] Reference Figure 3 , Figure 4 The adjusting member 13 includes a first adjusting ring 131 fixed in the water inlet joint 7, and a plurality of first adjusting holes 132 are provided through the first adjusting ring 131, and the plurality of first adjusting holes 132 are arranged at equal intervals along the circumference of the first adjusting ring 131. A second adjusting ring 133 is fixedly connected to the bottom of the support tube 3, and the second adjusting ring 133 is aligned with the first adjusting ring 131, and the inner diameters of the first adjusting ring 131 and the second adjusting ring 133 are the same. At the same time, a plurality of second adjusting holes 134 are provided through the second adjusting ring 133, and the number and inner diameter of the plurality of second adjusting holes 134 are the same as those of the plurality of first adjusting holes 132, and the plurality of second adjusting holes 134 can be aligned or misaligned with the plurality of first adjusting holes 132.

[0031] When the support tube 3 rotates, the first adjustment holes 132 and the second adjustment holes 134 are repeatedly aligned and misaligned, so that the flow rate of clean water entering the support tube 3 changes in real time. At this time, the atomizing nozzle 5 can swing in the vertical direction under the combined action of water pressure and its own gravity, that is, the atomizing nozzle 5 can also swing in the vertical direction during the rotation process, further increasing the spraying area of ​​the atomizing nozzle 5, thereby improving the dust reduction effect.

[0032] Reference Figure 3 , Figure 5 Two locking members 14 are provided on the support seat 4, and the locking members 14 are used to limit the rotation of the corresponding hinge shaft 12. When the staff needs the atomizing nozzle 5 to spray in a specific direction, the locking members 14 can be used to limit the corresponding hinge shaft 12, so that the staff can use the dust suppression device according to actual needs.

[0033] Reference Figure 3 , Figure 5Each locking member 14 includes a locking plate 141, a locking screw 142 and a plurality of locking grooves 143. The locking plate 141 is fixedly sleeved on the corresponding hinge shaft 12. The locking screw 142 is threadedly connected to the corresponding locking plate 141. The plurality of locking grooves 143 are respectively arranged on the support seat 4. The plurality of locking grooves 143 are arranged at equal intervals along the circumference of the corresponding locking plate 141, and the locking screw 142 can be threadedly connected to any locking groove 143. The locking member 14 can not only fix the atomizing nozzle 5, but also fix the atomizing nozzle 5 at multiple positions to increase the angle adjustment range of the atomizing nozzle 5.

[0034] Reference Figure 2 , Figure 4 , identification lines 15 are respectively provided on the water inlet joint 7 and the support pipe 3. When the two identification lines 15 are aligned, the multiple first adjustment holes 132 are aligned one by one with the multiple second adjustment holes 134, so that the staff can confirm whether the water inlet joint 7 is connected with the support pipe 3 and ensure the maximum water inflow, thereby improving practicality.
