PURPOSE: To attempt the inhibition of dust formation during spraying a material, improvement in an adhesion rate, the inhibition of plugging caused by the adhesion of the material, etc., by attaching oscillating members to the front and the rear of the bent part of a nozzle.
CONSTITUTION: In the case of a nozzle aimed at spraying at a right angle to a conveying pipe, the first oscillating body 3 is extended from a liquid-injecting part 2 to the vicinity of a bent part while the second oscillating body 5 is provided at the bent part from the rear of the bent part toward a spraying nozzle 1, and air injecting parts 4, 6 are provided to effectively operate each oscillating body. Consequently, each oscillating body 3, 5 has effects on the sufficient dispersion of a fluid into a material and the protection of the interior of the pipe from being coated with the material as well as the inhibition of dust formation because of the sufficient dispersion of the material water. In addition, the length l2 from the bent part to the spraying nozzle 1 can be shortened.
