Detailed Description
The utility model discloses a coal-winning machine is spraying dust device A for rocking arm (can be abbreviated as spraying dust device), as shown in fig. 1, 2, including arc spraying casing 3, nozzle 4, plinth 5 and water supply rubber tube 6, arc spraying casing is the cavity bar structure of convex extension, adopts convex structure can effectively enlarge spraying dust fall scope. The nozzles are distributed at intervals and are mounted on the arc-shaped spraying shell, and the nozzles are obliquely mounted towards the axial front and radial outer sides of the arc-shaped spraying shell, which refer to a mounting included angle alpha in fig. 2. One end of the joint seat can be connected and communicated with the arc-shaped spraying shell through a sealing thread, and the other end of the joint seat is connected and communicated with one end of the water supply rubber pipe. The water supply rubber tube is used for providing required spraying water for the spraying dust-settling device. The spraying dust-settling device can distribute water for spraying dust-settling to each nozzle, and then the water is sprayed to the roller through the nozzles, so that the spraying dust-settling range is greatly expanded, and a better spraying dust-settling effect is obtained.
