The following disadvantages were found during use:

[0003] 1. When transporting coal on a belt transport assembly, different types of coal generate different concentrations of coal dust during transportation, and the number of L-shaped sprinkler pipes on the existing sprinkler assembly is constant. The L-shaped sprinkler pipe cannot be installed or removed according to the concentration of coal dust. For coal mines with high humidity, spraying water mist on the coal mines will easily increase the humidity of the coal mines. For dry coal mines, spraying water mist on the coal mines will not reduce the coal dust to a suitable concentration. At the same time, the L-shaped sprinkler pipe is generally a certain distance away from the belt. When the coal mine belt transport sprinkler device is moved to other locations, it is easily affected by the L-shaped sprinkler pipe, which makes it inconvenient to move the coal mine belt transport sprinkler device.

The motor can drive the driving wheel to rotate, and since the belt 102 connects the driving wheel and the driven wheel, it can simultaneously drive the driven wheel to rotate, so that the belt 102 also moves, realizing the transportation of coal mines.

[0026] The watering assembly 2 includes a support frame 201 fixedly arranged on one side of the transport frame 101, and a delivery pipe 202 is fixedly arranged on the support frame 201, a water pump 203 is fixedly arranged through the delivery pipe 202, a plurality of diverter pipes 204 are evenly distributed and fixedly arranged through the top of the delivery pipe 202, a connecting pipe 205 is rotatably connected to the top of the diverter pipe 204, an L-shaped watering pipe 207 is movably sleeved on the outside of the connecting pipe 205, and a plurality of nozzles 209 are arranged at the bottom of the L-shaped watering pipe 207 above the belt 102, and a reinforcing plate 208 is fixedly arranged at the bend of the L-shaped watering pipe 207. The delivery pipe 202 is connected to an external water source, and the water pump 203 can draw the water pump 203 into the delivery pipe 202, and divert it to each connecting pipe 205 through the diverter pipe 204, and then spray it out from the nozzle 209 of the L-shaped watering pipe 207.

[0027] A blowout prevention assembly 3 is provided in the shunt pipe 204 to prevent water from spraying out from the top of the shunt pipe 204, and a pushing member 206 for pushing the blocking plate 304 on the blowout prevention assembly 3 is provided at the bottom end of the connecting pipe 205. The blowout prevention assembly 3 includes a truncated cone-shaped baffle 301 fixedly arranged in the shunt pipe 204, and the top and bottom of the truncated cone-shaped baffle 301 are connected, and a circular ring 302 is fixedly connected to the inner side of the truncated cone-shaped baffle 301 near the top through a plurality of connecting rods 1, and a blocking plate 304 is fixedly connected to the bottom of the circular ring 302 through a spring 303, and the pushing member 206 is fixedly connected to the inner wall of the connecting pipe 205 through a plurality of connecting rods 2, and the pushing member 206 is inserted into the shunt pipe 204, the circular ring 302, and the spring 303 in sequence to push the blocking plate 304.

Since the length of the bellows 402 is telescopic, when the height of the L-shaped sprinkler pipe 207 changes, the length of the bellows 402 can also change.

[0029] The working principle of this utility model:

[0030] When the height of the L-shaped sprinkler pipe 207 needs to be adjusted, the threaded ring 401 can be rotated to move the threaded ring 401 on the connecting pipe 205, thereby driving the L-shaped sprinkler pipe 207 to move, so that the length of the corrugated pipe 402 in the movable slot also changes.
