Specifically, the first check valve 3 is disposed in an end of the first radial duct 102 near the first waterway 2, so as to prevent water in the first waterway 2 from flowing into the first radial duct 102.
In some embodiments, the cross-sectional area of the first water channel 2 is greater than the cross-sectional area of the vane water channel 101, such that the water storage in the first water channel 2 is greater than the water storage in the vane water channel 101, to ensure that water in the vane water channel 101 can smoothly flow into the first water channel 2 through the first radial duct 102.

The coal cutter roller provided by the embodiment can ensure that the second radial pore canal 502 on the end disc 5 is not blocked by the blocking object in the second water channel 6, and meanwhile, water in the second water channel 6 is sprayed onto the cutting pick assembly 9 on the coal cutter roller through the second spraying assembly 8 positioned on the second water channel 6, so that the second spraying assembly 8 is ensured to cool and dust suppression on the cutting pick assembly 9 under the condition that the water quantity is relatively sufficient.
Further, the spray water channel structure comprises a second water channel 6, a second one-way valve 7 and a second spray assembly 8, wherein the second water channel 6 is arranged close to the peripheral end surface of the end disc 5, extends along the peripheral direction of the end disc 5 and is communicated with the second radial pore canal 502; a second one-way valve 7 is arranged in one end of the second radial duct 502 close to the second water channel 6, and is used for preventing water in the second water channel 6 from flowing into the second radial duct 502; the second spray assembly 8 communicates with the second water way 6 for spraying water in the second water way 6 onto the pick assemblies 9 on the shearer drum.
It will be apparent to those skilled in the art that various modifications and variations can be made to the present invention without departing from the spirit or scope of the invention. Thus, it is intended that the present invention also include such modifications and alterations insofar as they come within the scope of the appended claims or the equivalents thereof.
