The scattering device is for scatter material such as synthetic fertilizer where there is a supply container with an outlet orifice and a reciprocating scatter nozzle of plastic material which connects to this outlet orifice. The wall of the sprinkler nozzle consists of an outer relatively stiff layer (4) to achieve sufficient strength and an inner relatively flexible layer (5) as protection against the friction action of the material to be scattered. The flexible inner layer (5) extends from the feed orifice (6) of the nozzle (2) up to additional outlet orifices (8). This inner layer (5) can be made of rubber. |
