[0002] A coal mine is a reasonable space excavated by humans when digging geological strata rich in coal. It usually includes tunnels, shafts, and mining faces. During the mining process, a lot of coal slag dust remains inside the tunnel. In order to increase the comfort of the mining environment, the use of dust removal devices can effectively reduce the dust inside the tunnel and reduce the amount of dust inhaled by workers.

[0003] In the prior art, a Chinese patent with authorization announcement number CN217431228U discloses a dust removal device for coal mines, including a box, a first dust removal structure is arranged on the top of the box, a second dust removal structure is arranged on the bottom of the box, and a fixed plate is arranged on one side of the second dust removal structure. By arranging a water spray port inside the box, the air sucked into the box can be dusted, and the dust falls on the surface of the filter screen. Then, the second water pump is used to provide the filtered water to the mist nozzle in the second dust removal structure to spray clean water into the air, thereby dusting the air outside the box. It can not only improve the dust reduction efficiency, but also play a role in water circulation, effectively solving the problem that the dust removal device for coal mines used in the past is difficult to achieve water circulation and is not energy-saving and environmentally friendly.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Embodiment 1:

[0031] like Figure 1 , Figure 4 , Figure 5 and Figure 6 The technical solution shown in the figure is to solve the problem that scale impurities remain inside the box during the continuous water flow inside the dust removal device, and it is necessary to filter them. However, the filter screen will be clogged by scale after long-term use: the coal mine intelligent mining road dust removal device discloses a filtering mechanism, including an installation box 1, the interior of the installation box 1 is slidably connected to a movable plate 15, and a water storage tank 2 is arranged on the top of the movable plate 15, the top of the water storage tank 2 is connected to a spray pipe 3 through a hose, the interior of the water storage tank 2 is fixedly connected to a partition plate 21, and the upper end of the partition plate 21 A filtering mechanism for reducing impurities inside the water tank 2 is provided, the filtering mechanism includes a filter screen 22, and the filter screen 22 is fixedly connected to the upper end of one side of the partition plate 21, a connecting rod 4 is rotatably connected to the inside of the water tank 2 on one side of the partition plate 21, and a plurality of fixing boxes 5 are fixedly connected to the outside of the connecting rod 4, a cleaning brush 7 is fixedly connected to one side of the inside of the fixing box 5 through a connecting spring 6, and one side of the cleaning brush 7 is fitted with the filter screen 22, one side of the connecting spring 6 is connected to the inside of the fixing box 5, and an elastic mechanism is formed between the other side of the connecting spring 6 and the cleaning brush 7;

[0032] A sealing mechanism is provided on one side between the installation box 1 and the water tank 2, and the sealing mechanism includes a sealing layer 20, and the sealing layer 20 is fixedly connected to the upper end of the inner side of the installation box 1, and the inner side of the sealing layer 20 is in contact with the outer side of the water tank 2. The bottom end of the movable plate 15 is fixedly connected with an airbag 19, and both ends of the airbag 19 are connected to the sealing layer 20 through a hose.

[0033] In this example, by installing the water tank 2 inside the installation box 1, the weight of the water tank 2 and the weight of the water inside can be used to apply pressure to the airbag 19, so that the gas inside the airbag 19 is squeezed and transported to the inside of the sealing layer 20 through the hose, thereby filling the gap between the water tank 2 and the installation box 1, avoiding the positional deviation of the water tank 2 during the spraying process, and making the water tank 2 more stable during use;

[0034] By passing water into the water tank 2, the partition plate 21 divides the water tank 2, and the filtered water enters the other side of the water tank 2, and the spray pipe 3 and the water pump cooperate with each other to spray and remove dust, and the water that has just entered the water tank 2 is filtered by the filter 22, so that the water on one side of the water tank 2 is kept clean, effectively reducing the accumulation of impurities in the water tank 2, and also avoiding the situation that the spray pipe 3 cannot discharge water due to clogging of impurities during spraying;

[0035] During the water flow, as water flows in from the top of the water tank 2, it will continuously hit the fixed box 5, causing the fixed box 5 and the connecting rod 4 to continuously rotate, so that the cleaning brush 7 on one side of the fixed box 5 will rub and clean the filter screen 22 during the rotation process to prevent impurities from clogging the filter screen 22, thereby extending the service life of the filter screen 22.

[0036] Embodiment 2:

[0037] like Figure 1 , Figure 2 , Figure 4 and Figure 7 The technical solution shown is to solve the problem that the height of the spray pipe 3 is not easy to adjust during the spraying process, resulting in a fixed spray height and affecting the dust removal effect: the coal mine intelligent mining and dust removal device adopts a roadway dust removal device, and discloses a spray height adjustment mechanism.

The fixed rod 11 is internally slidably connected to the movable rod 12, and the spray pipe 3 is snap-connected to the inside of the movable rod 12. One end of the bottom end of the movable rod 12 is fixedly connected to a connecting block 9, and one end of the fixed rod 11 is provided with a limiting groove 13 matching the connecting block 9, and one end of the connecting block 9 passes through and extends to one end of the limiting groove 13, the top of the cam 8 fits with the bottom end of the connecting block 9, and the bottom end of the movable rod 12 is fixedly connected to a reset spring 10.

[0038] In this example, when the connecting rod 4 rotates, the cam 8 is driven to rotate through the belt. When the cam 8 rotates, it continuously moves the connecting block 9, so that the movable rod 12 inside the fixed rod 11 drives the spray pipe 3 to move up and down, thereby adjusting the spray height, facilitating the spraying of different areas, and increasing the work efficiency during dust removal.

[0039] Embodiment three:

[0040] like Figure 1 and Figure 3 The technical solution shown is to solve the problem that the water tank 2 continues to work when there is no water inside: the coal mine intelligent mining adopts a roadway dust removal device, and an alarm mechanism is disclosed. The installation box 1 at the lower end of the movable plate 15 is fixedly connected to the inside of the fixed plate 14, and the bottom end of the fixed plate 14 is provided with an alarm mechanism for automatically cutting off the power when there is no water. The alarm mechanism includes a guide rod 16, and the guide rod 16 is fixedly connected to the four corners of the bottom end of the movable plate 15. The bottom end of the guide rod 16 passes through the movable plate 15 and is fixedly connected to a conductive sheet 18, and a buffer spring 17 is wound around the outside of the guide rod 16, and the top end of the buffer spring 17 is connected to the bottom end of the movable plate 15, and the bottom end of the buffer spring 17 is connected to the top of the fixed plate 14.

[0041] In this example, when there is no water inside the water tank 2, the weight of the water tank 2 decreases, the buffer spring 17 resets and drives the movable plate 15 to move upward, so that the conductive sheet 18 at the bottom end of the guide rod 16 and the conductive sheet 18 at the bottom end of the installation box 1 are separated. When the conductive sheets 18 are separated, the power is automatically cut off and the spray irrigation stops.
