[0002] In construction, it is inevitable to use building materials such as sand that are easy to generate dust. In order to avoid excessive diffusion and generation of dust and protect the surrounding environment, a dust reduction device is used to reduce the generation of dust. There is currently a dust reduction device for construction (application number: 202321784314.6). The user can start the motor to rotate the circular shaft, and the circular shaft rotates with the mounting seat, so that the water tank can rotate accordingly, thereby increasing the spraying range, thereby increasing the dust reduction range, and improving the practicality of the device.

[0003] The above-mentioned existence, although the water tank can drive the nozzle to rotate, expand the spraying range and dust reduction range, but the height of the nozzle is fixed. If the passing truck is loaded with construction materials that are easy to raise dust, the dust generated by the bumps of the truck during movement may not be convenient to handle due to the limited height of the nozzle water spraying, which will cause the dust to spread, and has certain shortcomings.

A rod is fixedly connected to the nozzle, and a plurality of groups of holes are processed on the frame. Bolts are threadedly connected to the rod, and the outer wall of the bolt is gap-matched with the corresponding hole.

[0007] Preferably, one end and the other end of the platform are both fixedly connected with supports.

[0008] Preferably, a motor is installed on the platform, and groove wheels are fixedly connected to the output end of the motor and the frame, and two groups of groove wheels are rotatably connected by belts.

[0009] Preferably, a pump body is mounted on the platform, and one end of the pump body is rotatably connected to one end of the bellows via a bearing.
