The spraying device includes an annular body with a plurality of atomizing nozzles 5 arranged in a circular array on the outer side of the annular body. A liquid chamber is provided inside the annular body, and the atomizing nozzles 5 are connected to the liquid chamber through a flexible connecting pipe 14. A water inlet pipe 3 is provided on the annular body. An adjustment mechanism is also provided between the atomizing nozzles 5 and the annular body to adjust the pitch angle of the atomizing nozzles 5.

[0023] The upper end of the hopper body is connected to the hoisting cable 4, and the cargo is grabbed by two grab bucket components 1 on the hopper body. During unloading operations of coal, ore, and other cargo, the spray device at the upper end of the hopper body can be activated. Water mist is sprayed onto the vicinity of the hopper through the atomizing nozzles 5 on the spray device, achieving a dust suppression effect and reducing dust near the hopper, thereby improving the environmental quality near the work site. The atomizing nozzles 5 are arranged in a circular array on the outer side of the annular structure, ensuring uniform spraying and allowing the water mist to cover the area around the hopper, improving the dust suppression effect. The water inlet pipe 3 is connected to an external water supply device. When the spray device is working, water is supplied to the liquid chamber inside the annular structure through the water inlet pipe 3, and then the water is sprayed out in the form of water mist through each atomizing nozzle 5.

[0024] An adjustment mechanism is provided between the atomizing nozzle 5 and the annular body. The pitch angle of the atomizing nozzle 5 can be adjusted through the adjustment mechanism, thereby adjusting the spray direction of the water mist and achieving good results.
