Large-volume mine cars are favored by mining companies. In order to unload ore with such large-volume mine cars, the commonly used unloading stations in large mines currently include curved track side unloading stations, bottom side unloading stations and bottom unloading stations.

[0003] The Chinese patent CN212148820U specification discloses a bottom-unloading mine car unloading station. The utility model provides an unloading station that cooperates with the bottom-unloading mine car. The driving device is set at the entrance and exit, which can control the train to pass through the unloading station smoothly, which is convenient for the mine car to unload ore continuously and quickly. The lowest point of the unloading curved track can cooperate with the mine car door to reach a maximum angle of 45-55 degrees. The mine car has a large opening size, which can also facilitate the delivery of larger ores. The utility model will improve the transportation efficiency of the mine, enhance the safety performance of the mine, and reduce the maintenance cost of infrastructure.

[0004] Most traditional unloading stations lack structures for handling dust. The dust generated when the mine car is unloading will be scattered everywhere, which will have a great impact on the surrounding working environment and the health of the workers. Utility Model Content

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the utility model is that most traditional unloading stations lack a structure for handling dust.

[0007] In the above-mentioned bottom-dumping mine car unloading station, the dust generated during the loading and unloading process can be effectively reduced.

[0008] As a further improvement of the present application, a sleeve shaft is fixedly connected to the back of the spray head, and the sleeve shaft is sleeved on the surface of the rotating shaft.

[0009] As a further improvement of the present application, a clamping plate is symmetrically fixedly connected to the top of the connecting plate, an automatic rebound shaft is rotatably connected between the two clamping plates, and a gauze is wound around the surface of the automatic rebound shaft.

[0010] As a further improvement of the present application, the top cross-section of the mine car body is symmetrically fixedly connected with an arched electric slide rail, and the bottom of the arched electric slide rail is fixedly connected to the mine car body in the shape of a solid partition, a slide plate is fixedly connected to one end of the gauze, and the slide plate is slidably connected to the arched electric slide rail through a slider.

[0011] As another improvement of the present application, the surface of the water tank is covered with a baffle, and the baffle is fixedly connected to the inner wall of the mining car body.

While unloading, the water suction pump can be started to transport the water in the water tank to the water storage pipe through the water pipe, and then water mist can be sprayed through the spray head to suppress the dust generated by unloading. At the same time, the motor can be turned on to drive the rotating shaft to drive the spray head to adjust the spray angle up and down, thereby meeting the purpose of multi-directional dust reduction, and effectively achieving the effect of reducing the dust generated during the loading and unloading process.

[0024] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0025] The first implementation method:

[0026] Figure 1-2 and Figure 4-7A bottom-unloading mine car unloading station is shown, including a mine car body 1, characterized in that: a connecting plate 4 is symmetrically fixedly connected to the side end of the mine car body 1, a water storage pipe 6 is fixedly connected to the inner wall of the connecting plate 4, a plurality of drainage holes 17 are equidistantly drilled on the side wall of the water storage pipe 6, a clamping plate 15 is symmetrically fixedly connected to the water storage pipe 6 on the side of the drainage hole 17, a rotating shaft 14 is rotatably connected to the inner wall of the connecting plate 4 on the side of the water storage pipe 6, and the rotating shaft 14 passes through the clamping plate 15, a supporting plate is fixedly connected to the end of the connecting plate 4 away from the water pipe 5, a motor 16 is fixedly connected to the supporting plate, and the output end of the motor 16 is connected to the rotating shaft 14 A spray head 12 is fixedly connected to the side wall of the rotating shaft 14 located between the two clamping plates 15, and the spray head 12 is connected to the drainage hole 17 through a connecting pipe 13. A water tank 2 is fixedly connected to the inner wall of the mine car body 1. A water outlet 3 is drilled at the bottom of the side end of the mine car body 1. A water pipe 5 extending into the water storage pipe 6 is threadedly connected to the water outlet 3. A sleeve shaft 19 is fixedly connected to the back of the spray head 12, and the sleeve shaft 19 is sleeved on the surface of the rotating shaft 14. A baffle is covered on the surface of the water tank 2, and the baffle is fixedly connected to the inner wall of the mine car body 1. A water suction pump is installed in the water tank 2, and the output end of the water suction pump is connected to the water pipe 5.

[0027] This solution can be achieved when the mine car body 1 is used to transport ore. The mine car body 1 filled with ore can be driven to the unloading location, and then the bottom unloading port can be opened to unload the material. While unloading, the water suction pump is turned on to transport the water in the water tank 2 to the water storage pipe 6 through the water pipe 5, and then the water mist is sprayed through the spray head 12 to suppress the dust generated by the unloading. At the same time, the motor 16 can be turned on to drive the rotating shaft 14 to drive the spray head 12 to adjust the spray angle up and down, thereby meeting the purpose of multi-directional dust reduction, and effectively achieving the effect of suppressing the dust generated during the unloading and unloading process.

[0028] The second implementation method:

[0029] Figure 1-3 It is shown that a clamping plate 8 is symmetrically fixedly connected to the top of the connecting plate 4, an automatic rebound shaft 9 is rotatably connected between the two clamping plates 8, a gauze 10 is wound around the surface of the automatic rebound shaft 9, an arched electric slide rail 7 is symmetrically fixedly connected to the top cross-section of the mine car body 1, and the bottom of the arched electric slide rail 7 is fixedly connected to the mine car body 1 in a solid partition shape, a slide plate 11 is fixedly connected to one end of the gauze 10, and the slide plate 11 is slidably connected to the arched electric slide rail 7 through a slider, a protective net 18 is fixedly connected to the end of the connecting plate 4 away from the mine car body 1, and the protective net 18 covers the outside of the spray head 12.

[0030] This solution can be achieved. When loading into the mine car body 1, the arched electric slide rail 7 can be driven to drive the gauze 10 to move to the side of the splint 8, so that the gauze 10 can be automatically rolled up through the automatic rebound shaft 9 to open the mine car body 1. At this time, loading can be carried out. After loading, the gauze 10 can be moved in the opposite direction of the splint 8 through the arched electric slide rail 7, so that the gauze 10 is unfolded and spread on the top of the mine car body 1, which can cover the filled ore to avoid falling and dust during transportation. When using the spray head 12 for dust reduction, since the protective net 18 is covered on the outside of the spray head 12, it can avoid the ore splashing onto the spray head 12 and causing damage.

[0031] In view of current practical needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of this utility model.
