Nozzle closing device comprised of a main duct (2) traversed perpendicularly by a flexible pipe (6) which may be inflated with compressed air to obturate the pulverization liquid passageway. The device may be comprised of two generally orthogonal conduits enabling to sealingly secure a flexible pipe (6) into one of the conduits, the other conduit being used as the main conduit for the pulverization liquid. The end which carries the spreading device may consist of a nozzle attachment by means of a spraying hooking of a nozzle support. |
