Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of dust reduction, and in particular relates to a dust reduction device for coal mining. Background Art
[0002] Coal is the primary solid fuel and a type of combustible organic rock. It originates from plants that flourished during specific geological periods. Under favorable geological conditions, they gradually accumulated into thick layers and were buried under water or in mud and sand. Over vast geological ages, these plant debris underwent natural coalification, ultimately forming coal. Coal is an extremely important resource with a wide range of uses. However, coal mining often involves harsh environmental conditions, including high temperatures and dust. To address this, spray dust suppression systems are installed within coal mine tunnels to help excess dust settle to the surface.
[0003] In the prior art, a Chinese utility model patent with authorization announcement number CN217152013U discloses "a spray dust reduction device for coal mine tunnel mining", which includes a mobile platform, a dust reduction platform is installed on the upper surface of the mobile platform, a water storage chamber is provided inside the dust reduction platform, a collecting bucket is installed on the upper surface of the dust reduction platform, a fixed box is installed on the upper surface of the dust reduction platform, a drive box is installed inside the fixed box, a water pump is installed inside the fixed box, a water inlet pipe of the water pump extends to the inside of the water storage chamber, and a water outlet pipe of the water pump extends to the inside of the drive box and is connected to a vertical pipe through a rotary joint.
[0004] Although the current mining dust reduction equipment can effectively filter dust and allow water to flow into the water storage chamber through micropores to prevent the formation of ground sludge, and part of the water can be recycled to achieve energy-saving effects, however, in actual applications, when used in coal mine tunnels, since the roads are not always flat, there may be inclined road conditions. Although the wheels on the mobile platform can be self-locking, the water storage chamber needs to store a large amount of water resources for emergency use, which increases the weight borne by the wheels. At the same time, the strong vibrations generated by the water pump and drive motor at startup will also threaten the stability of the mobile platform, resulting in a decrease in the stability of the device. Long-term use may cause damage to the wheel self-locking structure, which in turn affects the normal fixing effect of the equipment.
[0005] In order to solve the above problems, this application proposes a coal mine excavation dust reduction device. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0025] See also Figure 1-Figure 4 The utility model provides the following technical solutions: a coal mine excavation dust reduction device, comprising a bearing plate 1, wheels 2 are fixed to the four corners of the bottom of the bearing plate 1, a support frame 4 and a handle 3 are fixed to the top, a water tank 5 is fixed to the bearing plate 1 through the support frame 4, water pipes 8 are fixed on both sides of the water tank 5, a plurality of atomizing nozzles 10 are installed on the two water pipes 8, and a water inlet 6 is also installed on the top of the water tank 5;
[0026] A water pump 7 is also fixed on the top of the supporting plate 1. One end of the water pump 7 is connected to the water tank 5 through a hose, and the other end is connected to a connecting pipe 9 through a hose. The two ends of the connecting pipe 9 are respectively fixedly connected to two water pipes 8.
[0027] The top of the carrying plate 1 is also rotatably connected to two symmetrically distributed turntables 11, and screws 12 are installed on the two turntables 11 through threads. The bottoms of the two screws 12 are rotatably connected to a fixed plate 13. The top of the fixed plate 13 is fixed with two symmetrically distributed guide rods 14, and the bottom is fixed with a plurality of fixing parts 15. The tops of the two pairs of guide rods 14 pass through the carrying plate 1. A handle 17 is also fixed to the top of the turntable 11, and the two turntables 11 are connected to each other by a belt. When in use, water is first poured into the water storage tank 5 through the water inlet 6, and then the water pump 7 is started. The water is pumped to the connecting pipe 9 through the hose and evenly distributed to the water pipes 8 on both sides. Since the water pipe 8 is equipped with an atomizing nozzle 10, the water is atomized into fine water droplets when passing through the nozzle, forming an atomizing effect, which effectively reduces the dust concentration in the coal mining area.
[0028] When used on an inclined road surface, the handle 17 can be rotated clockwise to rotate the turntable 11 and the screw 12. At the same time, one end of the guide rod 14 is penetrated through the supporting plate 1 to make the fixed plate 13 and the guide rod 14 descend synchronously. Several fixing parts 15 can be inserted into the flat or uneven ground. Through the belt, the two turntables 11 can rotate synchronously, so that the several fixing parts 15 on both sides of the supporting plate 1 can move at the same time, ensuring that the device can be stably fixed on the inclined road surface for use. Even if the water tank 5 is filled with water, the device can maintain good stability. At the same time, it can also avoid the vibration generated when the water pump 7 is started to affect the stability of the device, thereby reducing damage to the self-locking structure of the wheel 2, extending the service life of the equipment, and making the device easier to use at the coal mining site more safe and efficient.
[0029] Specifically, by Figure 1 As shown, in this embodiment, the height of the guide rod 14 is consistent with the height of the screw rod 12, ensuring that when the height of the device is adjusted, the fixing member 15 can be evenly inserted into the ground, thereby providing stable support.
[0030] Specifically, by Figure 4 As shown, in this embodiment, the bottoms of several fixing members 15 are provided with anti-slip grooves 16; this increases the friction with the ground and further improves the stability of the device under different terrain conditions.
[0031] Specifically, by Figure 1 As shown, in this embodiment, the outer wall of the water tank 5 is further provided with a perspective window 18; it is convenient for the user to check the water level in the water tank 5, ensure timely replenishment of water, and avoid a decrease in dust reduction effect due to lack of water. The design of the perspective window 18 allows the operator to quickly check the water level without opening the box cover, thereby improving the convenience of use.
[0032] Specifically, by Figure 1 、 Figure 2 and Figure 4As shown, in this embodiment, the screw 12, the fixing plate 13, the guide rod 14 and the fixing member 15 are all made of metal, which ensures the durability and reliability of the device and is suitable for long-term use in harsh environments such as coal mines.
[0033] Components not described in detail herein are prior art.
[0034] The working principle and use process of the utility model are as follows: when in use, water is first poured into the water storage tank 5 through the water inlet 6, and then the water pump 7 is started. The water is pumped to the connecting pipe 9 through the hose and evenly distributed to the water pipes 8 on both sides. Since the water pipes 8 are equipped with atomizing nozzles 10, the water is atomized into fine water droplets when passing through the nozzles, forming an atomization effect, which effectively reduces the dust concentration in the coal mining area;
[0035] When used on an inclined road surface, the handle 17 can be rotated clockwise to rotate the turntable 11 and the screw 12. At the same time, one end of the guide rod 14 is penetrated through the supporting plate 1 to make the fixed plate 13 and the guide rod 14 descend synchronously. Several fixing parts 15 can be inserted into the flat or uneven ground. Through the belt, the two turntables 11 can rotate synchronously, so that the several fixing parts 15 on both sides of the supporting plate 1 can move at the same time, ensuring that the device can be stably fixed on the inclined road surface for use. Even if the water tank 5 is filled with water, the device can maintain good stability. At the same time, it can also avoid the vibration generated when the water pump 7 is started to affect the stability of the device, thereby reducing damage to the self-locking structure of the wheel 2, extending the service life of the equipment, and making the device easier to use at the coal mining site more safe and efficient.
[0036] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
