[0046] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0047] As shown in Figure 1 and Figure 2 Embodiment one of the present application provides a blowing device, which comprises a main body 24, a stone roller assembly 21 and a blowing assembly 25. The main body 24 has a feeding end 241 for inputting a to-be-blown member and a discharging end 242 for outputting the to-be-blown member. The stone roller assembly 21 is arranged on the main body 24 and is used for bearing the to-be-blown member, one side of the stone roller assembly 21 is arranged towards the feeding end 241 and the other side is arranged towards the discharging end 242; the stone roller assembly 21 comprises a first roller body 211 and a second roller body 212 which are arranged at intervals, the first roller body 211 and the second roller body 212 are both rotatably arranged, and the rotation direction of the first roller body 211 is opposite to that of the second roller body 212. The surfaces of the first roller body 211 and the second roller body 212 are both provided with spiral protrusions. The blowing end of the blowing assembly 25 is arranged towards the stone roller assembly 21, and the blowing end is used for blowing out gas.

[0048] The walking roller assembly 21 is designed to enable the to-be-swept piece to form linear motion when entering the main body part 24, and the sweeping is completed in the linear motion, thereby improving the uniformity of the to-be-swept piece, avoiding the accumulation of the material, and providing favorable conditions for subsequent sweeping. The sweeping end of the sweeping assembly 25 can directly act on the surface of the to-be-swept piece, ensuring that the blown gas can completely remove the dust and impurities on the surface of the to-be-swept piece, improving the efficiency and effect of the sweeping. Moreover, the rotating roller body can help to peel off the dust and impurities attached to the surface of the to-be-swept piece through friction between the roller body and the to-be-swept piece, so as to better remove the dust and impurities through sweeping, avoiding the problem of incomplete material processing caused by uneven sweeping, and improving the efficiency and product quality of the whole production line. Therefore, the sweeping device provided by the embodiment can solve the technical problem that the dust and impurities attached to the surface of the coal gangue are not easy to clean in the prior art.

[0049] Specifically, the to-be-swept piece is coal gangue.

[0050] Specifically, the first roller body 211 and the second roller body 212 are both arranged in an extending manner along the direction from the feeding end 241 to the discharging end 242. By adopting such a structural arrangement, the extending directions of the first roller body 211 and the second roller body 212 are aligned with the material conveying direction, so that the material can be smoothly pushed forward when entering the walking roller assembly 21, reducing the situation of material jamming or poor conveying. At the same time, this helps the to-be-swept piece to form linear motion when entering the main body part 24, and the sweeping is completed in the linear motion, thereby improving the uniformity of the to-be-swept piece, avoiding the accumulation of the material, and providing favorable conditions for subsequent sweeping.

[0051] Specifically, the interval between the first roller body 211 and the second roller body 212 is smaller than the minimum distance between the opposite two points at the outer edge of the coal gangue.

[0052] Specifically, the first roller body 211 and the second roller body 212 can rotate relative to each other. From the direction of the walking roller assembly 21 to the feeding end 241, the first roller body 211 rotates in the clockwise direction, and the second roller body 212 rotates in the counterclockwise direction. From the direction of the main body part 24 from above to the main body part 24, the first roller body 211 rotates toward the middle of the first roller body 211 and the second roller body 212, and the second roller body 212 rotates toward the middle of the first roller body 211 and the second roller body 212.

[0053] Specifically, the rotation direction of the spiral protrusions on the first roller body 211 is opposite to that of the spiral protrusions on the second roller body 212. With such a structural arrangement, the oppositely rotating spiral protrusions can uniformly disperse the material layer on the stone-rolling roller assembly 21, avoiding local material accumulation and improving the uniformity and efficiency of the blowing. The opposite rotation direction of the spiral protrusions can effectively prevent the material from moving in the opposite direction during conveying, ensuring the one-way and stable conveying of the material. Through the relative rotation of the spiral protrusions, the dust and impurities adhering to the surface of the material can be more thoroughly removed by friction, improving the cleanliness of the material and creating better conditions for the subsequent intelligent gangue selection process.

[0054] Specifically, the main body part 24 is in a square structure. In this way, the square structure provides a stable carrying platform, which helps to maintain the structural stability of the entire device and the smoothness during the material conveying process. The square boundary helps to guide the material into a specific conveying path, avoiding deviation of the material from the predetermined track during conveying, thereby ensuring smooth passage of the material through the entire blowing process.

[0055] Specifically, the blowing assembly 25 includes a blowing head 22 and a support frame 251, the blowing head 22 forming a blowing end; the support frame 251 is arranged on the main body part 24, and the blowing head 22 is arranged on the support frame 251; the support frame 251 is arranged protruding from the main body part 24 and extending in the direction from the feeding end 241 to the discharging end 242. With such a structural arrangement, the blowing head 22 is fixed on the main body part 24 through the support frame 251, ensuring that the blowing gas can be accurately sprayed onto the object to be blown, improving the targeting and effect of blowing. The protruding design and extension arrangement of the support frame 251 increase the stability of the blowing assembly, preventing displacement or vibration during operation and ensuring the reliability of the blowing process.

[0056] Specifically, the blowing head 22 is a plurality of, and the plurality of blowing heads 22 are arranged in intervals in the direction from the feeding end 241 to the discharging end 242. In this way, the blowing heads 22 are arranged in the direction of material conveying and can be continuously blown as the material moves, avoiding blowing dead angles and improving the continuity and efficiency of blowing. The arrangement of multiple blowing heads 22 can ensure that the material is comprehensively blown in a longer conveying path, improving the coverage and uniformity of blowing.

[0057] Specifically, the main body 24 has a first side 243 and a second side 244 arranged oppositely, and the first side 243 and the second side 244 are arranged in a preset direction perpendicular to the direction from the feeding end 241 to the discharging end 242. The support frame 251 is arranged on one of the first side 243 and the second side 244, or the support frame 251 is arranged between the first side 243 and the second side 244. With such a structure, the support frame 251 can be arranged on the first side 243 or the second side 244, or between the two, which provides flexibility in the arrangement of the blowing head 22 to achieve the best blowing effect according to the specific application scenario. At the same time, when the support frame 251 is arranged between the first side 243 and the second side 244, it can help to improve the compactness of the overall structure, and by arranging the blowing head 22 on the opposite sides of the support frame 251, the efficiency of blowing can be improved.

The blowing head group is at least two, and one of the at least two blowing head groups is arranged on one side of the support frame 251, and the other is arranged on the other side of the support frame 251. With such a structure, by arranging multiple groups of blowing heads 22, blowing can be performed from both sides of the support frame 251 to ensure that the ore is subjected to all-round blowing during transportation, improving the comprehensiveness and effectiveness of blowing. The configuration of multiple groups of blowing heads 22 can simultaneously blow the ore in multiple areas, significantly improving the blowing efficiency and shortening the operation time. The support frame 251 is arranged between the two opposite sides to provide stable support, which is conducive to improving the overall structural stability of the blowing device and the positioning accuracy of the blowing head 22.

[0059] Specifically, the stone roller assembly 21 is at least two, and the at least two stone roller assemblies 21 are arranged in a preset direction. In this way, the arrangement of multiple stone roller assemblies 21 improves the processing capacity of the ore, which can simultaneously process more ore and is suitable for high-flow and high-efficiency production environments.

[0060] Specifically, the support frame 251 is provided with a ventilation pipeline, and the blowing head 22 is connected to the ventilation pipeline. With such a structure, the internal arrangement of the ventilation pipeline can ensure stable supply of blowing gas, avoiding leakage or supply interruption that may be caused by external pipeline connection. Integrating the ventilation pipeline into the support frame 251 reduces external components, making the entire blowing device more compact and improving the integration and space utilization of the equipment.

By adopting such structure, the rotation of the first roller body 211 and the second roller body 212 can be accurately synchronized through the design of the synchronous chain 214 and the synchronous wheel, the material jamming and wear caused by asynchronization are avoided, and the stable conveying of the material is ensured.

[0062] Specifically, the driving member 213 is a motor, and the driving member 213 is connected with one of the first synchronous wheel 215 and the second synchronous wheel 216 through a chain. Specifically, the synchronous chain 214 forms an "∞" shape.

[0063] Specifically, the surfaces of the first roller body 211 and the second roller body 212 are provided with wear-resistant materials.

[0065] In the embodiment, the blowing device further comprises a dust collecting member 4 arranged on one side of the main body 24, the dust collecting member 4 has a dust collecting space and a dust collecting port 401 communicating with the dust collecting space, and the dust collecting port 401 is arranged towards the stone roller assembly 21. The blowing device further comprises a suction member, and a suction end of the suction member communicates with the dust collecting space. With the arrangement, the dust collecting port 401 of the dust collecting member 4 is arranged towards the stone roller assembly 21, so that dust and impurities generated during the blowing process can be directly guided into the dust collecting space, and dust is prevented from flying everywhere and polluting the working environment. The arrangement of the suction member can provide power for dust entering the dust collecting space, and dust in the dust collecting space can be sucked out in time to prevent secondary pollution caused by dust accumulation, and dust can be conveniently collected and recycled. Through the dust collecting and suction system, the need for cleaning the environment during equipment maintenance is reduced, and the maintenance cost and labor intensity are reduced.

[0067] Specifically, the dust collecting member 4 comprises a dust collecting main body 42 and a dust collecting cap 41 connected with each other, the dust collecting port 401 is arranged on the dust collecting cap 41, and at least part of the dust collecting cap 41 is arranged above the stone roller assembly 21 and protrudes from the dust collecting main body 42. With the arrangement, the protruding design of the dust collecting cap 41 makes the coverage area larger, so that dust above and around the stone roller assembly 21 can be effectively captured, and the dust collecting efficiency is improved. The arrangement and direction of the dust collecting port 401 can guide the dust generated by the stone roller assembly 21 in a direction, so that the dust is prevented from spreading, and efficient collection of the dust is ensured.

[0068] Specifically, the blowing device further comprises a material collecting tank 217 arranged on the main body 24 and below the stone roller assembly 21, a tank opening of the material collecting tank 217 is arranged towards the stone roller assembly 21, and the material collecting tank 217 is arranged in communication with the dust collecting space.
