[0002] In building construction, earthwork, material handling, mechanical operation and other links will produce a large amount of dust, which not only pollutes the atmospheric environment, but also threatens the health of construction personnel and surrounding residents, so the spraying dust fall device becomes the key equipment to control dust.

[0003] At present, the spraying dust fall device commonly used in construction site is arranged with water spray pipe and atomizing nozzle at a specific height of construction fence, and the dust is adsorbed by spraying mist. However, such device has the following defects: the position of atomizing nozzle is fixed, so that the spraying range is limited to the fixed area. When the position of dust source in construction site changes (such as the transfer of dust focus area in different construction stages), or the range of construction site is adjusted (such as the change of dust source position caused by the change of transportation vehicle route), the fixed nozzle cannot flexibly adjust the spraying range and angle, and it is difficult to accurately cover the dust area, so the dust fall effect is limited.

[0020] By rotating adjusting branch pipe 6, the angle of adjusting branch pipe 6 is adjusted by the rotation of connecting piece 5 in shaft support 4, and atomizing nozzle 9 is flexibly adjusted by damping bearing seat 8. The water in main water delivery pipe 3 flows into adjusting branch pipe 6 through thick connecting hose 7, and then is delivered to atomizing nozzle 9 through thin connecting hose 10, realizing multi-angle and wide-range spray dust falling.

[0021] Referring to Fig. 2 Fig. 3 The limiting mechanism includes a first toothed disc 11 fixedly installed on the support shaft at one end of the connecting piece 5 and extending outside the shaft support 4, a fixed plate 12 fixedly installed at one end of the construction fence 1 near the first toothed disc 11, a limiting screw 13 threadedly connected at one side of the fixed plate 12, a second toothed disc 14 fixedly installed at one side of the limiting screw 13, the second toothed disc 14 movably located near one side of the first toothed disc 11, and the multiple clamping teeth at one side of the second toothed disc 14 located in the multiple clamping grooves at one side of the first toothed disc 11, the first toothed disc 11 and the second toothed disc 14 being engaged with each other,
