[0026] The angle adjusting assembly is composed of a motor 12, a worm 13 and a worm gear 9, the motor 12 is installed on the support column 7, a main shaft of the motor 12 is connected with the worm 13, the worm 13 is connected with the worm gear 9 in a matched mode, a rotating disc 8 is connected with a side of the worm gear 9, the rotating disc 8 is rotationally connected with the support column 7, and the spray pipe 10 is installed on a side wall of the rotating disc 8.

[0027] When the motor 12 is started, the main shaft thereof rotates and transmits power to the worm 13 connected therewith. The worm 13 is closely matched with the worm gear 9, and under the driving of the worm 13, the worm gear 9 starts to rotate. Since the rotating disc 8 is connected with a side of the worm gear 9 and the rotating disc 8 is rotationally connected with the support column 7, the rotation of the worm gear 9 drives the rotating disc 8 to rotate synchronously. Since the spray pipe 10 is installed on a side wall of the rotating disc 8, the spray position of the spray pipe 10 can be adjusted along with the rotation of the rotating disc 8, and the dust falling operation can be flexibly performed at different positions, so that the coal mining face can be more comprehensively and effectively covered.

[0028] A spray water recovery assembly is arranged on the floor surface 1 below the spray pipe 10, and an outlet end of the spray water recovery assembly is connected with the water tank 3.

[0029] The spray water recovery assembly comprises a backflow slope 15, a low end of the backflow slope 15 is provided with a backflow groove 16, an outlet end of the backflow groove 16 is provided with a drain pipe 17, an outlet end of the drain pipe 17 is connected with a converging pipe 19, an outlet end of the converging pipe 19 is connected with a backflow pump 20, and the backflow pump 20 is connected with the water tank 3 through a backflow pipe 21.

[0030] When the dust-settling device is in operation, the sprayed water will fall on the ground surface 1 after accomplishing the dust-settling task. The ground surface 1 is provided with a spray water recycling assembly which can effectively recycle the sprayed water. Specifically, the ground surface 1 is designed in the form of a backflow slope 15 so that the sprayed water naturally flows along the slope to a low end, and a plurality of backflow grooves 16 are arranged at the low end to collect the water flow. The outlet end of each backflow groove 16 is connected to a drain pipe 17, and the water flow is collected through the drain pipe 17 to a collecting pipe 19, and then at the outlet end of the collecting pipe 19, the water is pumped by a backflow pump 20 and is transported back to the water tank 3 through a backflow pipe 21, realizing the recycling of the sprayed water, saving water resources, and ensuring the continuous and stable operation of the dust-settling device.

[0031] The ground surface 1 is provided with a working shed 2, and the support column 7 is located in the working shed 2.

[0032] The motor 12, the worm 13 and the worm gear 9 are provided with a protective frame 11 around them, and the protective frame 11 is connected to the working shed 2.

[0033] The entire dust-settling device for the coal mining face is arranged in the working shed 2, providing a relatively stable and protected working environment for the equipment. At the same time, in order to ensure the safe operation of the angle adjusting assembly, the protective frame 11 is arranged around the motor 12, the worm 13 and the worm gear 9, and the protective frame 11 is connected to the working shed 2, effectively preventing external factors from interfering with and damaging the assembly, and ensuring the reliable operation of the dust-settling device.

[0034] The backflow grooves 16 are provided in a plurality.

[0035] In use:

[0036] First, the water in the water tank 3 is extracted and pressurized by the transport pump 5 through its water outlet pipe 4, and then the water is transported upward along the output pipe 6 provided in the support column 7. The motor 12 is started to drive the worm 13 to rotate the worm wheel, and then the rotating disc 8 is rotated to drive the spray pipe 10 to rotate. After rotating to the required angle, the motor 12 is turned off, and then the transport pump 5 is started to extract the clean water inside the water tank 3. After the clean water flows into the output pipe 6, it is lifted through the pipeline inside the support column 7 and then flows into the spray pipe 10. Then the clean water is sprayed out to form fine water mist, which diffuses in the coal mining working area to effectively reduce the dust concentration in the air. During the dust reduction process, the sprayed water mist slowly accumulates on the floor surface 1 to form a water flow that flows into the return flow groove 16 through the return flow slope 15, and then enters the drain pipe 17. After flowing through the buffer pipe 18 and the confluence pipe 19, it is lifted into the return flow pipe 21 by the return flow pump 20, and finally re-enters the water tank 3. Thus, the water circulation process of the entire device is completed, providing safety guarantee for the coal mining process.
