[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0020] like Figures 1 to 6 As shown, a hopper with a dust suppression spray function includes a hopper body, which includes two relatively rotatable grab bucket components 1. A spray device is provided at the upper end of the hopper body. The spray device includes two semi-annular pipes 2, which are connected to each other to form an annular structure. A liquid chamber 10 is provided inside the semi-annular pipe 2, and a plurality of atomizing nozzles 5 are provided on the outside of the semi-annular pipe 2. The atomizing nozzles 5 are connected to the liquid chamber 10. A water inlet pipe 3 is connected to the semi-annular pipe 2. A collision buffer device is provided on the outside of the hopper components.

[0021] 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, thus 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 10 inside the semi-annular pipe 2 through the water inlet pipe 3, and then the water is sprayed out in the form of water mist through each atomizing nozzle 5.

[0022] During actual unloading operations, the outer side of the hopper may collide with some facilities on the ship's hold or dock. In this invention, a collision buffer device is provided on the outer side of the hopper component. The collision buffer device can reduce the impact force generated by the impact and reduce the damage caused by the impact.

[0023] The semi-annular tube 2 is provided with connecting plates 8 at both ends, and bolt holes are provided on the connecting plates 8. The connecting plates 8 of the two semi-annular tubes 2 are connected by connecting bolts 9. The bottom of the semi-annular tube 2 is provided with a positioning block 6, and a positioning groove 7 is provided on the positioning block 6. The upper end of the hopper body is provided with a positioning element 11 corresponding to the positioning groove 7, and the positioning element 11 is inserted into the positioning groove 7.

[0024] In this invention, the spraying device is assembled from two semi-annular tubes 2, which are fixedly connected by connecting bolts 9. This structure facilitates the installation and disassembly of the spraying device. When installing the spraying device, the positioning piece 11 at the upper end of the hopper body is inserted into the positioning groove 7 at the bottom of the semi-annular tube 2, and then the two ends of the two semi-annular tubes 2 are connected by connecting bolts 9. The spraying device is fixed to the upper end of the hopper body through the cooperation between the positioning piece 11 and the positioning groove 7. When disassembling the spraying device, simply remove the connecting bolts 9 between the two semi-annular tubes 2, and then the semi-annular tubes 2 can be removed from the hopper body.

[0025] In this embodiment, the positioning element 11 is L-shaped.

[0026] Furthermore, the collision buffer device includes an energy-absorbing box 12 and a crash plate 13. The energy-absorbing box 12 is fixedly mounted on the outer surface of the grab bucket component 1, and the crash plate 13 is located on the side of the energy-absorbing box 12 away from the grab bucket component 1. The crash plate 13 and the energy-absorbing box 12 are connected by a spring 14. During operation, when the crash plate 13 on the grab bucket component 1 collides with an external object, the spring 14 located between the crash plate 13 and the energy-absorbing box 12 can effectively buffer the impact and reduce the damage caused by the impact. If the impact force is too large, while the spring 14 plays a buffering role, the excessive impact force will cause the energy-absorbing box 12 to deform under the force. The deformation of the energy-absorbing box 12 absorbs part of the impact kinetic energy, thus playing a further buffering role.

[0027] The energy-absorbing box 12 is a box structure made of steel plate, and an energy-absorbing cavity is set inside the energy-absorbing box 12. The thickness of the steel plate of the energy-absorbing box 12 is 1.2-1.8 mm.

[0028] This utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
