Description

Technical Field

[0001] The utility model relates to a dust suppression device, in particular to a spray dust suppression device for a coal mining working face. Background Art

[0002] A hydraulic support spray dust suppression device for coal mining faces is used to control coal mine dust, protect worker health, and prevent coal dust explosions. Traditional dust suppression methods, such as sprinkling and spraying, have limited effectiveness, waste resources, and are difficult to maintain.

[0003] 1. Traditional equipment adopts a fixed structure and cannot flexibly adjust the height and angle, making it difficult to adapt to different terrain conditions. On working surfaces with complex terrain or large changes, fixed hydraulic supports are prone to unstable support or insufficient bearing capacity. The height and angle adjustment of traditional hydraulic supports mainly rely on manual operation. The adjustment process is cumbersome, time-consuming and labor-intensive, and cannot quickly respond to the changing needs of the working surface. Traditional hydraulic supports lack a precise adjustment mechanism, and manual adjustment often fails to meet high-precision requirements, affecting the stability and safety of the support. In the absence of a high-strength spiral adjustment mechanism, the adjustment efficiency of traditional supports is low, which increases the difficulty of operation and labor costs. Therefore, there is an urgent need for a spray dust suppression device with a hydraulic support design.

[0004] 2. Traditional equipment relies on incandescent or fluorescent lamps, which not only have high energy consumption and short lifespans, but also easily generate a large amount of heat, increasing the temperature of the working environment and affecting workers' work comfort and efficiency. In addition, traditional lighting equipment has a limited lighting range and uneven light distribution, resulting in shadow areas on the work surface, failing to provide sufficient and uniform lighting, and increasing safety risks in operations. Traditional lamps are fixed installations and lack flexible adjustment functions. They cannot adjust the lighting angle and direction according to actual needs, making it difficult to achieve all-round lighting. Moreover, traditional lighting equipment has high maintenance costs. Frequent replacement of lamps increases equipment downtime and maintenance costs, reducing overall work efficiency. Therefore, there is an urgent need for a spray dust suppression device with a multifunctional lighting design.

[0005] 3. Traditional equipment relies on water sprinkling and simple spray systems for dust reduction. Water sprinkling for dust reduction easily leads to a waste of water resources, and a large amount of water will make the ground muddy, affecting the operation and safety of the work surface. At the same time, the spray effect of the traditional spray system is uneven, the coverage is limited, and it cannot effectively capture and suppress the fine dust particles suspended in the air, resulting in a still high dust concentration. Traditional dust control equipment lacks an effective airflow control mechanism and cannot prevent the spread of dust through airflow barriers. Traditional equipment lacks an intelligent control system and cannot automatically adjust dust control measures based on real-time monitoring data, which limits the dust prevention effect. In the absence of high-efficiency fans and piping systems, the airflow output of traditional dust control equipment is unstable, and the dust prevention effect is difficult to achieve the ideal state, affecting the health and safety of workers. Therefore, there is an urgent need for a spray dust reduction device with a multi-functional dust removal design. Utility Model Content

[0006] The utility model aims to provide a spray dust reduction device for a coal mining working face, which solves the problem that the current dust reduction device cannot flexibly adapt to different environments.

[0007] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is:

[0008] A spray dust reduction device for a coal mining working face comprises a mobile platform, an adjustment component, a workbench and a dust reduction component; the workbench is arranged on the mobile platform through the adjustment component, and the dust reduction component is connected to the mobile platform and the workbench respectively; a lighting lamp is also provided at the bottom of the workbench.

[0009] Furthermore, the mobile platform includes a chassis, a motor and tires; there are four tires divided into two groups, one group of tires is arranged at the front end of the chassis, and the other group of tires is arranged at the rear end of the chassis; the output end of the motor is connected to the tires respectively through transmission parts.

[0010] Furthermore, the adjustment assembly includes a sleeve rod, a primary telescopic column and a secondary telescopic column. The sleeve rod is obliquely connected to the chassis, the primary telescopic column is telescopically placed in the sleeve rod, and the secondary telescopic column is telescopically placed in the primary telescopic column; the secondary telescopic column is connected to the workbench; the primary telescopic column is threadedly connected to the sleeve rod, and the secondary telescopic column is threadedly connected to the primary telescopic column.

[0011] Furthermore, the dust reduction component includes a water tank, a high-pressure pump, a water pipe and a nozzle; the water pipe is connected to the water tank through the high-pressure pump, and the nozzle is connected to the other end of the water pipe.

[0012] Furthermore, the workbench is rotatably connected to an adjustment plate via a rotating shaft, and the nozzle is connected to the adjustment plate; the angle of the nozzle is adjusted by rotating the rotating shaft to change the angle of the adjustment plate.

[0013] Furthermore, an air distribution plate is provided at the bottom of the workbench, and a plurality of air guide ports are provided on the air distribution plate, and the air guide ports are evenly distributed on the air distribution plate; the air guide ports allow wind to disperse the water sprayed from the nozzle.

[0014] Furthermore, the lighting lamp adopts an LED lamp light source.

[0015] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0016] 1. The utility model adds an adjustment component, which can improve the adaptability and operational flexibility of the equipment. The adjustment component can adjust the height and angle of the workbench under different terrain conditions, so that it can maintain stability and load-bearing capacity in complex or highly variable environments. This design reduces the problems of working surface tilt and displacement caused by uneven terrain, ensuring the safety and stability of the working surface. The adjustment component achieves precise height and angle adjustment through the telescopic component, and manual operation can achieve a high-precision adjustment effect. It can also be equipped with an electric drive device to achieve a more convenient and efficient adjustment process. Traditional equipment is time-consuming and labor-intensive during the adjustment process, and it is difficult to meet high-precision requirements. The adjustment component can be adjusted quickly and accurately, significantly improving work efficiency and stability. The design of the combination of the adjustment component and the telescopic component not only reduces the difficulty of operation and labor costs, but also improves the overall performance and safety of the equipment, meeting the needs of modern coal mining work for equipment flexibility and adaptability.

[0017] 2. The utility model can improve the lighting effect and energy utilization efficiency by adding LED lamps and light sources. LED lamps are characterized by high efficiency, energy saving and long life, which not only reduces energy consumption, but also reduces the maintenance cost and downtime of frequent lamp replacement. Compared with traditional lamps, LED lamps generate less heat and will not increase the temperature of the working environment, thereby improving the work comfort and efficiency of workers. Traditional lighting equipment has a limited lighting range and uneven distribution, which easily forms shadow areas on the work surface, affecting the safety of operation. LED lamps can cover the entire work surface with high brightness and uniform light distribution, eliminate shadow areas, provide sufficient and uniform lighting, and significantly improve the safety of operations. In addition, LED lamps are equipped with adjustable lamp stands, which can flexibly adjust the lighting angle and direction according to actual needs to achieve all-round lighting. This flexible adjustment function enables the LED lighting system to adapt to different working environments and lighting needs, further improving work efficiency and safety.

[0018] 3. The utility model can enhance the dust prevention effect of the spray dust suppression device by adding an air distribution plate. By designing multiple air guide ports, the water mist sprayed from the nozzle can form a stable airflow barrier to prevent dust from spreading and effectively capture and suppress fine dust particles in the air. Traditional water sprinkling dust suppression methods easily cause water waste and muddy ground, while simple spray systems have uneven effects and limited coverage, and cannot completely solve the dust problem. The use of air distribution plates can improve the uniformity and coverage of the spray, and the air outlet direction and air volume can be adjusted through the adjustment plate to achieve the best dust prevention effect. The dust prevention device can adjust the air volume and wind direction of the air guide port in real time according to the dust concentration, ensuring that the best dust prevention effect can be achieved under different working conditions. Not only is the dust prevention efficiency improved, but the reliability and use effect of the overall equipment are also improved. By introducing air guide ports, the spray dust suppression device has been significantly improved in terms of dust prevention effect and resource utilization, and provides better protection for the health and safety of workers.

The water tank 31 is designed with a water inlet and a drain outlet to facilitate quick water addition and cleaning. At the same time, a filter is set inside the water tank 31 to prevent impurities from entering the spray system and ensure the unobstructed flow of the nozzle 34. The high-pressure pump 32 is used to pressurize the water in the water tank 31 and transport it to the nozzle 34 through a pipe. The use of an efficient and energy-saving high-pressure pump 32 can provide a stable and strong water flow to ensure a uniform spray effect. The high-pressure pump 32 is equipped with an overload protection device to prevent damage to the equipment under high load conditions. The workbench 2 is rotatably connected to an adjustment plate 35 via a rotating shaft 36, and the nozzle 34 is connected to the adjustment plate 35; the angle of the adjustment plate 35 is changed by rotating the rotating shaft 36 to adjust the angle of the nozzle 34, and the amount of air passing through the nozzle 34 via the air distribution plate is changed by adjusting the angle of the nozzle 34, thereby achieving the purpose of adjusting the line of sight barrier.
