[0020] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of a coal mine excavation dust suppression device of the utility model in conjunction with the accompanying drawings.
[0021] like Figures 1 to 3 As shown, a coal mine excavation dust reduction device of the utility model includes a bearing plate 1, a first pillar 13 is symmetrically arranged on the top surface of the bearing plate 1 with respect to its center, and the two first pillars 13 are connected by a mounting plate 3, and a dust reduction component 4 is arranged on the mounting plate 3. At the same time, a water tank 2 is arranged on the bearing plate 1, and the dust reduction component 4 is connected to the water pump in the water tank 2 through a connecting pipe 8, and the water pump is electrically connected to an external power supply for power supply. Among them, the dust reduction component 4 includes a swing arm 41 rotatably arranged on the mounting plate 3, a shunt pipe 42 is arranged at the free end of the swing arm 41, and a nozzle 43 is distributed at the free end of the shunt pipe 42, and the shunt pipe 42 is connected to the pump in the water tank 2 through a connecting pipe 8. When the coal dust is to be reduced, the water pump can be started. The water pump will transport the water in the water tank 2 to the diversion pipe 42 through the connecting pipe 8. The water in the diversion pipe 42 will then be sprayed out through the nozzle 43. The nozzle 43 is an atomizing nozzle 43, which can atomize the water to better combine the water mist with the coal dust, thereby achieving a better dust reduction effect.
[0022] In order to increase the spraying range of the dust reduction assembly 4 during operation, a support arm 5 is further provided on the mounting plate 3. The support arm 5 is provided with a driving device 6 for driving the dust reduction assembly 4 to swing. The driving device 6 provided on the support arm 5 and cooperating with the dust reduction assembly 4 can make the swing arm 41 on the dust reduction assembly 4 swing back and forth when the dust reduction assembly 4 sprays water mist to reduce dust, thereby increasing the range of the dust reduction assembly 4 spraying water mist and improving the dust reduction effect of the dust reduction assembly 4 on coal dust. The driving device 6 includes a dual output shaft motor 61 provided on the support arm 5, the dual output shaft motor 61 is electrically connected to an external power supply, and a connecting plate 62 is provided at each output end of the dual output shaft motor 61, and an eccentric shaft 63 is provided at one end of the outer wall of the connecting plate 62. At the same time, a slide groove 7 is opened on the swing arm 41 along its length direction, and the eccentric shaft 63 is located in its corresponding slide groove 7, and the eccentric shaft 63 can slide in the slide groove 7. Start the dual output shaft motor 61, the dual output shaft motor 61 drives the connecting plate 62 to rotate, and the eccentric shaft 63 set on the connecting plate 62 will also rotate with the center of the connecting plate 62. When the eccentric shaft 63 rotates, it will slide back and forth in the slide groove 7. At this time, the eccentric shaft 63 will drive the swing arm 41 to start reciprocating swinging at the connection point with the mounting plate 3, so that the shunt pipe 42 connected to the swing arm 41 will reciprocate and swing, so as to achieve the purpose of increasing the spraying range of the nozzle 43 on the dust suppression component 4. It should be noted that the connecting pipe 8 is a hose, and the connecting pipe 8 between the shunt pipe 42 and the water tank 2 has a reserved length, which can be used when the shunt pipe 42 swings.
[0023] Still Figure 2As shown, the dual output shaft motor 61 is slidably arranged on the support arm 5, and the first electric push rod 12 is arranged on the mounting plate 3, the first electric push rod 12 is connected to the external power supply, and the telescopic end of the first electric push rod 12 is connected to the dual output shaft motor 61. The first electric push rod 12 can drive the position of the dual output shaft on the support arm 5, that is, the eccentric shaft 63 connected to the dual output shaft through the connecting plate 62 will also move in the slide groove 7 of the swing arm 41, so that the swing amplitude of the shunt pipe 42 driven by the swing arm 41 can be controlled, so that the dust reduction component 4 can be used for different ranges of coal dust reduction, and the dust reduction component 4 can improve the high efficiency of coal dust reduction.

The driving machine 10 drives the rotating disk 9 to rotate on the mounting plate, which can change the angles of the dust reduction assembly 4 provided on the rotating disk 9 and the various components on the support arm 5 relative to the mounting plate 3, so that the dust reduction assembly 4 can adapt to different usage scenarios and workspaces, and improve the practicality of the dust reduction assembly 4. In order to ensure the stability of the rotating disk 9 on the mounting plate 3, a limit buckle 11 is distributed around the center of the rotating disk 9 on the mounting plate 3. The limit buckles 11 are combined to form an installation space, and the limit buckles 11 are L-shaped. The rotating disk 9 rotates in the installation space formed by the limit buckles 11. The limit buckles 11 are detachably mounted on the mounting plate 3 by screws, which facilitates the disassembly and assembly of the rotating disk 9 at a later stage.
