[0002] Mining refers to the process of extracting economically valuable minerals and rocks from the earth's crust. Rocks include coal, metallic ores, oil, natural gas, and building stone. It is a fundamental industry for humankind to obtain natural resources and support industrial production and social development. Mining crushers are essential equipment in the mining and mineral processing process. They are mainly used to crush large blocks of raw ore or rock into smaller, more uniform particles to meet the requirements of subsequent beneficiation, smelting, transportation, or direct utilization. They are a key link connecting mining and deep mineral processing, directly affecting the efficiency and cost of subsequent processes. Processes such as beneficiation and smelting have strict requirements on material particle size. Crushers refine large blocks of raw ore into standard particle sizes through multi-stage crushing, ensuring that subsequent equipment can process them efficiently. However, existing mining crushers cannot suppress dust during operation, generating dust that affects the working environment and makes them inconvenient to use. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 This utility model provides a technical solution: a mining crusher with a dust suppression structure, including a crushing box 10, a feed trough 20, a guide plate 30, a motor 301, a rotating drum 302, a collection trough 303, a second motor 40, a crushing roller 401, a guide plate 402, a water tank 50, a water pump 501, a pipe 502, an atomizing nozzle 503, and a discharge port 504; This mining crusher can reduce dust generated during crushing, and the specific implementation method is as follows: A feed chute 20 is fixedly connected to the surface of the crushing box 10, and a second motor 40 is symmetrically mounted on the surface of the crushing box 10. A second guide plate 402 is symmetrically mounted on the inner wall of the crushing box 10, and a crushing roller 401 is symmetrically rotatably mounted on the inner wall of the crushing box 10. One side of the crushing roller 401 passes through the crushing box 10 and is connected to the output shaft of the second motor 40. A first guide plate 30 is symmetrically arranged on the inner wall of the feed chute 20, and a rotating drum 302 is rotatably mounted inside the feed chute 20. A collection trough 303 is embedded in the surface of the rotating drum 302, and a first motor 301 is connected to one side of the rotating drum 302 through the feed chute 20. The first motor 301 is mounted on the surface of the feed chute 20. A water tank 50 is connected to the surface of the crushing box 10, and a water pump 501 is mounted on the surface of the crushing box 10. A pipe 502 is connected to the surface of the water pump 501, and the pipe 502 is mounted on the surface of the crushing box 10 at equal intervals. The crushing box 10 has an atomizing nozzle 503, an inlet 504 embedded in its surface, an inclined plane at the bottom of the crushing box 10, and the inlet 504 located on the lowest side of the bottom surface of the crushing box 10. The feed chute 20 is rotatably connected to the rotating drum 302, and guide plates 30 are symmetrically arranged on both sides of the rotating drum 302. The bottom of the guide plates 30 is in contact with the surface of the rotating drum 302. The rotating drum 302 and the guide plates 30 are slidably connected, and the surface of the guide plates 30 is set as an inclined plane. Guide plates 402 are arranged on both sides of the crushing roller 401, and the surface of the guide plates 402 is inclined. The positions of the two crushing rollers 401 are correspondingly arranged, and the feed chute 20 is arranged between the two crushing rollers 401. The crushing rollers 401 are rotatably connected to the crushing box 10. The pipe 502 is located at the top of the inlet 504, and the end of the atomizing nozzle 503 is correspondingly arranged to the position of the inlet 504.

[0022] After the material is fed into the feed trough 20, the guide plates 30, symmetrically arranged on both sides, guide the material to the surface of the rotating drum 302 by means of an inclined plane, so that the material falls into the collection trough 303. The motor 301 is started, and the output shaft of the motor 301 drives the rotating drum 302 to rotate, so that the rotating drum 302 rotates inside the feed trough 20. The rotating drum 302 rotates at the bottom of the guide plate 30. At this time, the rotating drum 302 drives the collection trough 303 on its surface to rotate. When the collection trough 303 rotates to the bottom, the material inside the collection trough 303 is discharged by gravity, so that the material falls into the crushing box 10. At this time, the material falls between the two crushing rollers 401, and at the same time, the material is guided by the guide plates 402 on both sides. The material slides down into the gap between the two crushing rollers 401. At the same time, the second motor 40 starts, and the output shaft of the second motor 40 drives the crushing rollers 401 on the inner wall of the crushing box 10 to rotate. At this time, the two crushing rollers 401 rotating in opposite directions squeeze, shear and crush the material, breaking large pieces of material into fine particles that meet the requirements. Then the material falls onto the bottom surface of the crushing box 10 through the crushing rollers 401. Under the action of gravity, the material slides along the inclined plane to the discharge port 504 at the lowest point of the bottom surface. At the same time, the water pump 501 starts, pressurizes the water in the water tank 50 and transports it through the pipe 502 to the atomizing nozzle 503 at the top of the discharge port 504. The atomizing nozzle 503 atomizes the water into a fine water mist to reduce dust on the material discharged from the discharge port 504.
