There is often insufficient water supply in the water tank, or overflow, resulting in soaking of the working surface, and it is difficult to completely cover the working range. When the excavator moves, the fog cannon is difficult to keep up, slowing down the progress of the work and wasting manpower. In a small construction space, it is even difficult to set up a fog cannon.

[0023] An embodiment of the utility model provides a spray device for suppressing dust. The following is an explanation in conjunction with the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments.

[0024] like Figure 1 As shown, a dust suppression spray device can be connected to the excavator arm 2 and the bucket 10 of the excavator 1. The excavator arm 2 is rotatably connected to the bucket 10, and includes a water tank 3 arranged on the excavator 1, a water pipe 4 arranged along the excavator 1 and extending to the excavator arm 2, and a spray assembly. The water pipe 4 connects the water tank 3 and the spray assembly to form a spray pipeline. The spray assembly is rotatably connected to the water pipe 4 and connected to the bucket. The device can operate as the excavator moves, and the spray assembly sprays as the bucket rotates, so as to cover the operating range in time. It is particularly suitable for earthwork operations with small on-site space and insufficient manpower.

[0025] Preferably, the spray assembly includes a first water pipe 51 connected to the water supply pipe 4 via a bellows 53, a second water pipe 52, and a first adapter 54 connecting the first water pipe 51 and the second water pipe 52. A nozzle 55 is provided at the end of the second water pipe 52 away from the first adapter 54, and the first water pipe 51 is connected to the excavation arm 2 via a first fastener 56.
