An air inlet connector 4 is also provided on the end surface of the connection end 12, and the air inlet connector 4 is a quick connector seat for mining. The water inlet connector 3 and the air inlet connector 4 are symmetrically arranged along the horizontal direction of the connection end 12.

[0036] Reference Figure 2 A shock absorbing assembly 5 is fixedly connected to the top end surface of the box body 1. There are four groups of shock absorbing assemblies 5 and they are respectively arranged at the four corners of the top end surface of the box body 1. A fixing assembly 6 is fixedly connected to the side of the shock absorbing assembly 5 away from the box body 1. There are two groups of fixing assemblies 6 and they are both arranged along the length direction of the box body 1. Each group of fixing assemblies 6 is connected to two groups of shock absorbing assemblies 5. The fixing assemblies 6 are detachably connected with a hanging ring 65.

[0037] When installing the dust collector, a crossbar is erected above the conveyor belt according to the position to be fixed, and the fixing assembly 6 is adjusted to a suitable position according to the diameter of the erected crossbar. A steel wire is passed through the lifting ring 65 and fixed to the crossbar, so that the dust collector can be fixed on the crossbar above the conveyor belt, and a mining quick connector is used to connect the water pipe and the air pipe to the water inlet joint 3 and the air inlet joint 4 respectively. When the dust collector is working, the chamfer opened at the nozzle of the nozzle 2 can reduce the liquid residue at the nozzle, ensure that the nozzle 2 is not blocked and can spray water normally, and the five nozzles 2 are arranged along the arc surface of the spray end 11, which can form a fan-shaped mist spray, increase the area of ​​the water mist sprayed in the lane, and reduce the harm caused by dust to the staff. The shock-absorbing assembly 5 can reduce the impact of the vibration generated when the water spray is started and stopped and the conveyor belt is working on the dust collector, which can increase the stability of the dust collector, and ensure the normal operation of the dust collector. The position of the lifting ring 65 is adjusted by the fixing assembly 6, and the dust collector is fixed to the crossbar with a steel wire rope, which is convenient for the staff to install and maintain the dust collector.

[0038] Reference Figure 3 The shock absorbing assembly 5 includes a first connecting plate 51 and a second connecting plate 53. The first connecting plate 51 is fixed to the top surface of the box body 1. The length direction of the first connecting plate 51 is parallel to the length direction of the box body 1, and the two first connecting plates 51 located on the same side of the box body 1 are located on the same straight line. On the walls on both sides of the first connecting plate 51, there are first connecting holes on the side walls along the length direction of the first connecting plate 51. A plurality of first connecting holes are sequentially spaced along the length direction of the first connecting plate 51. The second connecting plate 53 is located on the side of the first connecting plate 51 away from the box body 1. A second connecting hole is opened on the side walls on both sides along the length direction of the second connecting plate 53.
