PROBLEM TO BE SOLVED: To reduce spray scattering in a self-traveling spraying machine with which a multihead nozzle pipe for downward spraying a liquid fed under pressure by a pump is supported on a machine body supported on wheels traveling in a field. SOLUTION: Scattering prevention covers 31-33 surrounding the circumference of ejection nozzle 12 arranged on the multihead nozzle pipe 5 are installed. The scattering prevention covers 31-33 are vertically opened. When a liquid is sprayed downward from the injection nozzle 12, upper air flows into a scattering prevention cover 30, an air stream flowing from the upper part into the lower part with vigor is produced, the spray flows downward with the air stream and attached to crops planted on ridges or surface soil. As a result, scattering of floating spray in the transverse direction is reduced and scattering by wind is controlled. COPYRIGHT: (C)2008,JPO&INPIT
