Abstract

PURPOSE:To eliminate the sediment perfectly by providing a nozzle fitting arm to a travelling truck, which is reciprocated on a frame, freely to be oscillated on the vertical surface, and fitting a nozzle to the tip of the nozzle fitting arm. CONSTITUTION:A frame body 76, in which a nozzle 269 is provided freely to be oscillated, is moved right and left on a frame 1 by the drive of a geared motor, and a nozzle fitting arm 78 is oscillated around of the base end by the drive of an arm oscillating device 77. When high-pressure water is supplied to a water supplying pipe 79, the high-pressure water is jetted from the tip of the oscillating nozzle fitting arm 78 to wash the surface of a material to be washed. Angle of oscillation of the arm 78 provided with the nozzle 269 is set in response to the range of washing of the material to be washed. In the case of washing a part at a small width, an angle of oscillation of the arm 78 is set small, and in the case of washing a part at a large width, an angle of oscillation of the arm 78 is set large. Consequently, a washing width can be easily decided by setting the angle of oscillation of the arm 78.
