The invention relates to the technical field of construction dust prevention, and discloses a road and bridge construction dust prevention device which comprises a protection plate, a motor is fixedly installed on the outer surface of the rear side of an adjusting box, a disc fixedly sleeves the outer surface of a rotating shaft, the other end of a telescopic rod is rotationally connected with an inverted-L-shaped rod, and a rack is arranged in the adjusting box. The outer surface of the vertical shaft is fixedly sleeved with a gear, limiting holes are formed in the outer surface of the side U-shaped plate and the outer surface of the positioning block, and T-shaped limiting rods are movably inserted into the limiting holes, corresponding to the positioning holes, of the side U-shaped plate. A motor drives a rotating shaft to drive a swing rod to enable a disc to rotate, a telescopic rod and an inverted-L-shaped rod are matched to enable a rack to drive a gear to rotate, an atomization spray head rotates, and therefore the atomization spray head is driven to move left and right in the working process of the motor, the dust falling range is adjusted, and the dust falling effect is improved; and the range of the rotating angle of the atomizing nozzle can be adjusted as required.
本发明涉及施工防尘技术领域,且公开了一种路桥施工防尘装置,包括防护板,所述调节箱的后侧外表面固定安装有马达,所述转轴的外表面固定套设有圆盘,所述伸缩杆的另一端转动连接有倒L形杆,所述调节箱的内部设置有齿条,所述立轴的外表面固定套设有齿轮,所述侧U形板和定位块的外表面均开设有限位孔,所述侧U形块和定位孔相对应的限位孔内活动插设有T形限位杆。通过马达驱动转轴带动摆动杆使得圆盘转动,配合伸缩杆和倒L形杆使得齿条带动齿轮转动,使得雾化喷头转动,从而在马达工作的过程中带动雾化喷头左右移动,调节降尘范围,提高了降尘效果,并且能够根据需要调整雾化喷头的转动角度的范围。
