Further, the water delivery main pipe 210 can be correspondingly installed along the length direction of the robot arm assembly 110, so that the lifting effect of the water delivery main pipe 210 on the robot arm assembly 110 is ensured. When the sprinkling dust suppression device is needed to perform surface sprinkling on the placed coal 10, water is delivered into the water delivery main pipe 210 through the water supply mechanism 300, the first control part 240 is opened, and the second control part 250 and the third control part 260 are closed at the same time, at this time, a water source in the water delivery main pipe 210 only passes through the first sprinkling part 220, so that the coal 10 is sprinkled by using the first sprinkling part 220.

Referring to fig. 2, in one embodiment, the water supply mechanism 300 includes a water supply part 310, a water storage tank 320 and a liquid level meter 330, the liquid level meter 330 is used for detecting the water level of the water source in the water storage tank 320, the water storage tank 320 is mounted on the movable base 120, one end of the water delivery main 210 is communicated with the water storage tank 320 through the water outlet of the water storage tank 320, and the water supply part 310 is communicated with the water storage tank 320. Specifically, the water supply part 310 may be a water supply tank or an external water pipe. The water and dust sprinklers often need to carry a large amount of water during operation, for example, the water storage tank 320 can store 50 tons of water. Therefore, the water storage tank 320 needs to consume a long time for water supplement each time, in order to avoid the situation that the water storage of the sprinkling dust suppression device is insufficient during operation, the liquid level meter 330 is used for monitoring the water source in the water storage tank 320, and when the water source in the water storage tank 320 is insufficient, a worker is timely reminded to supplement water to the water storage tank 320.

Referring to fig. 2, in one embodiment, the water supply mechanism 300 further includes a heating member mounted on the water storage tank 320. In particular, considering the large temperature differences between different seasons, for example: in winter, the water in the water storage tank 320 is easy to freeze, and in order to ensure that the sprinkling dust suppression device can be normally used, the water temperature in the water storage tank 320 can be regulated and controlled through the heating element to prevent freezing.

Referring to fig. 2, in one embodiment, the water supply portion 310 includes a water supply main tank 311, a first water supply pipe 312, and a plurality of water supply members 313, wherein a water source in the water supply main tank 311 is filled into the water storage tank 320 through the first water supply pipe 312 at a first flow rate, the plurality of water supply members 313 are spaced apart from each other in the yard, and the plurality of water supply members 313 are used for filling water into the water storage tank 320 at a second flow rate. Specifically, in order to improve the water replenishing efficiency in the water storage tank 320, the water feeding main tank 311 utilizes the first water feeding pipe 312 to continuously supply water to the water storage tank 320, that is, when the sprinkling dust suppression device works, the water source in the water feeding main tank 311 can be filled with water into the water storage tank 320 at a first flow rate through the first water feeding pipe 312, and the first flow rate can be adaptively adjusted according to the water pumping condition of the water delivery main pipe 210, that is, the first flow rate is prevented from influencing the water pumping of the water delivery main pipe 210. In addition, when the water spraying dust suppression device stops working, the corresponding water feeding piece 313 is selected according to the position of the water spraying dust suppression device at the parking position of the storage yard, and because the water spraying dust suppression device is in the shutdown state, the water feeding piece 313 can supply water to the water storage tank 320 at a second flow rate (for example, the second flow rate can be greater than the first flow rate), and meanwhile, the water feeding speed of the water feeding main tank 311 can be adaptively adjusted. At this time, the water feeding main groove 311 and the water feeding member 313 realize double-path water feeding to the water storage tank 320, and the water feeding efficiency of the water storage tank 320 is greatly improved.

Specifically, after the water-feeding member 313 is disposed at the yard, in order to avoid the influence of the water-feeding member 313 on the movement of the movable seat 120, when the water-feeding member 313 is not needed for water supply, the angle between the second water-feeding member 3134 and the second adapter 3133 may be changed, for example, the second water-feeding member 3134 is rotated toward the installation surface. When the water feeding member 313 is needed to supply water, the electric push rod 3131 can drive the second water feeding member 3134 to rotate relative to the second adapter 3133 until the second water feeding member 3134 can be connected to the anti-overflow joint 321 of the water storage tank 320, so that the water feeding member 313 can feed water into the water storage tank 320. Meanwhile, the second water feeding pipe 3134 may be effectively prevented from splashing outside during water replenishment by the overflow preventing joint 321.
