TECHNICAL FIELD
[0001] The utility model relates to the field of coal mine dust removal, concretely relates to an automatic spraying device for coal mine conveyer. BACKGROUND
[0002] Coal dust harms the health of workers, and contains a large amount of free silicon dioxide. When miners inhale these dusts for a long time, the dusts will deposit in the lungs, causing pulmonary fibrosis and pneumoconiosis. This is an irreversible occupational disease, which seriously affects the health and labor capacity of miners. Dust can stimulate the respiratory mucosa, causing respiratory diseases such as rhinitis, pharyngitis, and tracheitis. Long-term exposure to high dust environment can increase the risk of pneumoconiosis and pneumoconiosis. Not only that, but it can also pose an explosion hazard. When coal dust reaches a certain concentration in the air and encounters a fire source, an explosion can occur, producing high temperature, high pressure and shock waves, causing great damage to underground equipment, tunnels and personnel.
[0003] The source of coal mine dust is not only the dust generated during production, but also the dust generated during transportation. Because negative pressure ventilation is used underground, the coal gangue falls and is blown by the wind due to the height difference at the loading point of the transportation equipment, causing dust to fly. To solve this problem, a manual valve spray is installed at the loading point of the transportation equipment in the coal mine. The manual valve spray device is always in a spraying and watering state as long as the valve is opened, regardless of whether there is coal gangue passing through, causing excessive sludge and water accumulation on site, wetting the belt surface of the belt conveyor, and causing the belt conveyor to slip, affecting normal transportation.
[0004] In the prior art, there are common infrared automatic watering devices on the market, but the infrared automatic watering device needs to be driven by a power source, causing unnecessary resource waste. According to the above problems, a coal mine conveyor automatic spraying device is needed to reduce manual operation, save water, reduce sludge accumulation, and work normally without power supply.

[0033] Embodiment 1
[0034] The embodiment discloses an automatic spraying device for coal mine conveyor.
[0035] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 The embodiment includes an automatic spraying device 1, the automatic spraying device 1 includes a fixed assembly 2, a spraying assembly 3, a valve assembly 4, the fixed assembly 2 is arranged on the conveyor belt 15, the fixed assembly 2 fixes the spraying assembly 3 and the valve assembly 4;
[0036] The valve assembly 4 is used for sensing the material 18 passing through the automatic spraying device 1;
[0037] The spraying assembly 3 is connected with the valve assembly 4, and the valve assembly 4 controls the spraying assembly 3 to open and close.
[0038] The embodiment fixes the spraying assembly 3 and the valve assembly 4 on the conveyor belt 15 through the fixed assembly 2, the structure is stable, and the service life of the device is long;The utility model is provided with the valve assembly 4, the valve assembly 4 is used for sensing the material 18 passing through the automatic spraying device 1, and the spraying assembly 3 is controlled to open and close, the material 18 is realized automatic watering, and when the material 18 does not pass, it is in the closed state, saving water resources;The utility model is provided with the valve assembly 4, which does not need power supply driving, prevents the shell from being electrified due to the internal insulation damage of electrical equipment and other reasons, and causes the situation that the worker is electrocuted.
[0039] The fixed assembly 2 comprises two upright columns 5 arranged on both sides of the conveying belt 15 and a cross beam 6 arranged on the top surface of the upright columns 5, and the upright columns 5 are fixed to the conveying belt by bolts 17. In the embodiment, the upright columns 5 are fixed on both sides of the conveying belt 15, and in the implementation of the scheme, the upright columns 5 can also adopt a lifting structure, so that the height of the upright columns 5 can be adjusted to enable the conveying belt 15 below the cross beam 6 to convey larger-volume materials 18.
[0040] The valve assembly 4 comprises a liquid injection gun 7 fixed in the middle of the cross beam 6, and the liquid injection gun 7 is provided with a trigger 8, a water inlet 9 and a water outlet 10.
[0041] The trigger 8 is curved and inclined, and the trigger 8 is provided with a baffle 11 fixed to the trigger 8 by screws 12.
[0042] The materials 18 collide with the baffle 11 to control the opening of the spraying assembly 3.
[0043] The liquid injection gun 7 is a tool for injecting liquid into a specific device or container. When the liquid injection gun 7 is connected to a liquid source, the liquid fills the injection pipe under the action of the pressure difference. When the trigger 8 is not pulled, the valve is in a closed state, and the liquid is blocked in the gun body. When the operator pulls the trigger 8, the trigger 8 drives the valve to open, and the liquid stops injecting after the valve closes under its own pressure when the trigger 8 is released.

[0046] The distance between the bottom of the baffle 11 and the conveying belt 15 is 50-80 mm. If the distance is too large, the materials 18 cannot contact the baffle 11, which makes the automatic spraying device 1 work unsatisfactorily, and if the distance is too small, the automatic spraying device 1 is too sensitive and wastes unnecessary water resources.

For those skilled in the art, any equivalent modification and replacement of the utility model are also within the scope of the utility model.
