It includes a water tank, a base plate fixedly connected to the bottom of the water tank, a fixed shell fixedly connected to the top of the water tank, a motor and a bearing fixedly connected inside the fixed shell, a first bevel gear fixedly connected to the output shaft of the motor, a rotating shaft fixedly connected inside the bearing, and a second bevel gear fixedly connected to the bottom outer side of the rotating shaft.

[0004] The above-mentioned device, by setting up height adjustment and angle adjustment structures, allows the device to change the spray angle according to the dust suppression requirements during use, thereby improving the dust suppression effect. It is simple to operate and more convenient to use. By combining water tank storage and direct water supply through the water inlet pipe, the device can adjust the water supply mode according to the water supply situation, making it suitable for complex coal mining environments, reducing its limitations, and facilitating its widespread use.

[0005] While this device addresses the aforementioned shortcomings, its dust suppression direction and range are relatively fixed during spraying, resulting in a concentrated dust suppression effect. Additionally, the device is difficult to clean, leading to increased maintenance costs. Utility Model Content

[0014] In summary, this utility model has the following beneficial effects:

[0015] 1. This utility model uses an adjustment mechanism in conjunction with a dust suppression mechanism to control the drive sprocket to rotate around a rotary motor, thereby coordinating with the chain to drive the transmission sprocket to rotate, allowing the connecting rod to drive the rotating connecting seat and the dust suppression bucket to rotate in the same direction, thereby adjusting the direction and range of dust suppression and avoiding the problem of concentrated dust suppression effect;

[0016] 2. Simultaneously, a rotating connector is provided on one side of the rotating connector, and a support base is rotatably connected to the bottom of the rotating connector. An extension rod is provided on the bottom surface of the support base, allowing the extension rod to engage with the threaded rod to push the support base to move in the same direction, causing the dust collection bin to rotate around the rotating connector, raising the elevation angle of the dust collection bin, and realizing flexible adjustment of the spray angle; in conjunction with the slide groove to limit the rotation of the dust collection bin, the dust collection range of the device is further expanded;

[0017] 3. The dust collection bin is equipped with a cleaning brush.

[0026] The present invention will be further described below with reference to the accompanying drawings.

[0027] The orientations mentioned in this specification are based on the orientation of the dust suppression device for coal mining of this utility model when it is working normally. They do not limit the orientation during storage and transportation, and only represent relative positional relationships, not absolute positional relationships.

[0028] like Figures 1 to 4As shown in the figure, this utility model provides a dust suppression device for coal mining, including a device body 1, an adjustment mechanism 2 on the top of the device body 1, and a dust suppression mechanism 3 on the top of the adjustment mechanism 2; a lockable universal wheel 5 is provided on the bottom surface of the device body 1, and a controller 4 is provided on one side surface of the device body 1; in use, the adjustment mechanism 2 cooperates with the dust suppression mechanism 3 to adjust the direction and range of dust suppression, avoid the problem of concentrated dust suppression effect, and improve the cleaning efficiency of the device while reducing maintenance costs.

[0029] The adjustment mechanism 2 includes a rotating connecting seat 21 and a connecting rod 22 disposed on the bottom surface of the rotating connecting seat 21. A transmission sprocket 23 is disposed on the outer side of the connecting rod 22, and a drive sprocket 25 is disposed on one side of the transmission sprocket 23. The drive sprocket 25 and the transmission sprocket 23 are connected by a chain 24. The drive sprocket 25 is connected to a rotary motor 29. The rotary motor 29 drives the drive sprocket 25 to rotate around the rotary motor 29, thereby cooperating with the chain 24 to drive the transmission sprocket 23 to rotate, causing the connecting rod 22 to drive the rotating connecting seat 21 to rotate in the same direction, thereby driving the dust collection bin 31 to rotate, solving the problem of the dust collection effect being relatively concentrated in the existing device.

[0030] Furthermore, a rotating connector 26 is provided on one side of the rotating connector 21, and a support 27 is rotatably connected to the bottom of the rotating connector 26. An extension rod 28 is provided on the bottom surface of the support 27, and a sliding rod 210 is sleeved on the outer side of the extension rod 28. A threaded rod 212 is provided inside the sliding rod 210. The threaded rod 212 and the extension rod 28 are provided with matching threads. The threaded rod 212 is connected to a rotating motor 29. The rotating connector 21 is connected to the dust collection bin 31 through a rotating shaft. The threaded rod 212 and the extension rod 28 are provided with matching threads, which allow the threaded rod 212 and the extension rod 28 to rotate and fit together to achieve extension. The rotating motor 29 controls the rotation of the threaded rod 212, causing the extension rod 28 to fit into the threaded rod 212 and push the support 27 to move in the same direction. This causes the dust collection bin 31 to flip around the rotating connector 21, raising the elevation angle of the dust collection bin 31 and achieving flexible adjustment of the spray angle.

[0031] The top surface of the main body 1 of the device is provided with a groove 6, and auxiliary rotating wheels 211 are symmetrically arranged on both sides of the sliding rod 210; the rotating connector 26 is fixedly connected to the bottom surface of the dust collection bin 31, and the auxiliary rotating wheel 211 is embedded in the groove 6. The rotation and movement of the dust collection bin 31 are assisted and limited by the sliding of the auxiliary rotating wheel 211 inside the groove 6.

[0032] The dust suppression mechanism 3 includes a dust suppression bin 31 and an air inlet 32 ​​located at one side of the dust suppression bin 31. A fan 33 is located on one side of the air inlet 32. A mounting frame 310 is installed inside the dust suppression bin 31. A water spray nozzle 311 is installed on the surface of the mounting frame 310. The water spray nozzle 311 is connected to a water tank 312 via a connecting hose and a pump. An electric telescopic rod 34 is located on the opposite side of the air inlet 32 ​​inside the dust suppression bin 31. A protective cover 35 is located at the outer end of the electric telescopic rod 34. A spray hole 36 is provided on the protective cover 35. A transmission rod 37 is also provided on the inner side of the protective cover 35. A ring frame 38 is provided at the other end of the transmission rod 37. A cleaning brush 39 is arranged around the outer periphery of the ring frame 38. The electric telescopic rod 34 pushes the protective cover 35 to move in the same direction, thereby driving the transmission rod 37 to pull the cleaning brush 39 on the surface of the ring frame 38 to clean the inside of the dust suppression bin, thereby improving the maintenance and cleaning efficiency of the device.

[0033] Working principle: Before use, connect the device to the power supply and fill the water tank with clean water to ensure normal operation. The drive sprocket 25 is connected to a reciprocating motor 29. During use, the pump draws water from the water tank 312 to the sprinkler head 311, and then the fan 33 atomizes the water from the sprinkler head 311 and sprays it out through the spray hole 36. By controlling the rotation of the motor 29 of the threaded rod 212, the extension rod 28 engages with the threaded rod 212 to push the support base 27 to move in the same direction, causing the dust collection bin 31 to flip around the rotating connecting seat 21, raising the dust collection bin 31. The spray angle is adjusted flexibly by adjusting the elevation angle of the spraying. Then, the drive sprocket 25 is controlled to rotate around the rotary motor 29, which in turn drives the transmission sprocket 23 to rotate with the chain 24. This causes the connecting rod 22 to drive the rotating connecting seat 21 and the dust collection bin 31 to rotate in the same direction. At the same time, the sliding groove 6 limits the rotation of the dust collection bin 31, solving the problem of the dust collection effect being relatively concentrated in the existing device. After use, the protective cover 35 is moved in the same direction by the electric telescopic rod 34, which drives the transmission rod 37 to pull the cleaning brush 39 on the surface of the ring frame 38 to clean the inside of the dust collection bin, improving the maintenance and cleaning efficiency of the device.
