This utility model discloses an environmental engineering atomizing device, including a barrel, a tube shell, a support ring, a turntable, and an atomizing spray assembly. In this environmental engineering atomizing device, a tube shell is fixedly connected to the top surface of the barrel, concentrically arranged. A support ring is fixedly connected to the inner side of the top of the tube shell. A corresponding turntable is rotatably mounted on the top surface of the support ring. An annular rail is fixedly connected to the top surface of the support ring. An annular slider is fixedly connected to the bottom surface of the turntable. An atomizing spray assembly is installed through the center of the turntable. A drive motor is fixedly mounted on the bottom edge of the turntable. The comb-tooth end of the drive motor rotates through the turntable and is fixedly connected to a gear. A gear ring is provided on the outer side of the gear for meshing and transmission. The gear ring is fixedly connected to the inner wall of the tube shell. The drive motor drives the gear to rotate, and the gear rolls inside the gear ring, thereby causing the turntable to rotate on the support ring, enabling the atomizing spray assembly to achieve rotational atomization spraying, thus forming a uniform circumferential spraying effect.

The invention belongs to the technical field of tunnel construction, and particularly relates to a dust falling device for tunnel construction, which comprises a water tank, a water guide pipe is rotatably mounted on the inner wall of the water tank, a dust falling assembly is arranged on the outer side of the water guide pipe, and a mounting assembly for mounting the dust falling assembly is arranged above the water tank. An angle adjusting assembly used for adjusting the angle of the mounting assembly is arranged on the inner side of the mounting assembly, and a driving assembly is arranged on the inner side of the water tank. Through rotation of the dust falling assembly, the 360-degree spraying effect can be achieved, and no-dead-corner spraying is conducted on the surrounding environment, so that the dust falling coverage range is effectively widened, the dust catching efficiency is improved, and the problem that the dust concentration of a local area is too high due to angle limitation of traditional fixed dust falling equipment is solved; the angle adjusting assembly can adjust the angle of the dust falling assembly in a reciprocating mode, a three-dimensional dust falling space is formed by adjusting the angle of the dust falling assembly, and the dust falling effect of the device is improved.
