[0029] like Figure 1-6 As shown, this embodiment is implemented by the following technical solutions: the feed port of the crusher 6 is connected to the discharge port of the dust reduction box 3; the inlet of the dust reduction box 3 is connected to a collecting hopper 2 for gathering materials; a dust removal hood 1 for dust collection is provided on the side of the feed port of the collecting hopper 2, and the dust removal hood 1 is connected to an external dust removal system through a pipeline;

[0030] The dust generated when the waste ore enters the collecting hopper 2 is adsorbed by the dust removal hood 1 and the dust removal system.

[0031] A baffle mechanism 4 is hinged on the side of the inlet of the dust reduction box 3, and the baffle mechanism 4 blocks the inlet of the dust reduction box 3 to achieve blocking of the dust reduction box 3 and prevent the dust in the dust reduction box 3 from escaping to the outside.

[0032] A dust suppression nozzle 5 is provided on the inner wall of the dust suppression box 3, and the dust suppression nozzle 5 pipeline is connected to an external water source.

[0033] The dust suppression nozzle 5 comprises: a pipe body 502 , on which a plurality of nozzles 501 for spraying water mist are arranged.

[0034] A pipe interface 101 is provided on the dust removal hood 1, and a pipeline of the pipe interface 101 is connected to an external dust removal system.

[0035] Specifically, the dust reduction box 3 includes: a box body 301 , on the inner wall of the box body 301 are provided protection baffles 302 distributed in a scale shape, and the protection baffles 302 are inclined toward the side of the box body 301 where the discharge port is located.

[0036] A dust suppression nozzle 5 is arranged in the interval of the protective baffle 302 , and the protective baffle 302 resists the impact of the material on the dust suppression nozzle 5 , and prevents the waste ore falling during the feeding process from damaging the dust suppression nozzle 5 .

[0037] Specifically, a first baffle 303 for protecting the pipeline is provided on the outer surface of the box body 301; the first baffle 303 is arranged above the junction between the dust suppression nozzle 5 and the external water source pipeline. The first baffle 303 prevents the falling waste ore from damaging the pipeline.

[0038] Specifically, the baffle mechanism 4 includes: a second baffle 401, on which a rotating shaft 403 is provided; the rotating shaft 403 is hinged to the inner wall of the dust reduction box 3; a torsion spring 402 is sleeved on the rotating shaft 403, and the torsion spring 402 provides elastic support for the second baffle 401. The second baffle 401 is reset under the action of the torsion spring 402. In this embodiment, the number of second baffles 401 is 2, and the normal position of the second baffle 401 is horizontal. When the material falls on the second baffle 401, the second baffle 401 tilts downward under the action of the weight of the material, and the material slides along the baffle into the dust reduction box 3. When the gravity of the material on the second baffle 401 is less than the elastic force of the torsion spring 402, the second baffle 401 is reset, and the feed port of the dust reduction box 3 is closed.

[0039] The specific usage principles are as follows:

[0040] The waste ore is transported to the collecting hopper 2, and the dust removal hood 1 first absorbs the dust generated in this process. Further, after the waste ore enters the dust reduction box 3 through the baffle mechanism 4, the baffle mechanism 4 blocks the feed port of the dust reduction box 3, and the water mist generated by the dust reduction nozzle 5 mixes with the dust in the dust reduction box 3 to form tiny mud spots, preventing the dust from escaping outward.

The present invention is not limited to the above examples, and any equivalent changes and improvements made by ordinary technicians in the technical field within the essential scope of the present invention shall fall within the scope of the patent coverage of the present invention.
