and the control assembly is used for opening the nozzle and controlling the water pump to work when the coal mining machine carries out mining work, so that the nozzle sprays to dust fall the dust falling point.
2. The system of claim 1, wherein the spray assembly further comprises:
the driving assembly is telescopic and is connected with the nozzle.
3. The system of claim 2, wherein the drive assembly comprises a water tube drum and a hydraulic hose.
4. The system of claim 1, further comprising:
a filter disposed between the water tank and the spray assembly.
5. The system of claim 4, further comprising:
a switch assembly disposed between the water tank and the filter.
6. The system of claim 1, wherein the nozzle comprises:
a spray base;
at least one spray head disposed on the spray base.
7. The system of claim 1, further comprising:
the dust concentration sensors are respectively arranged in the discharging part, the conveying part and/or the platform protection part of the coal mining machine, so that when the dust concentration of any region is detected to be greater than a preset threshold value, the control assembly opens the nozzle corresponding to any region.
8. The system of claim 7, wherein the control component is further configured to close a nozzle corresponding to the any one zone when the dust concentration in the any one zone is less than the preset threshold.
9. The system of claim 1, further comprising:
a state detector for detecting an operating state of the plurality of nozzles;
and the alarm device is used for sending out alarm warning when the working state is abnormal.
10. A coal mining machine, characterized by comprising: a spraying system for a highwall coal mining kit as claimed in any one of claims 1 to 9.
