The irrigation device for seed beds is provided with a liq. supply pipe on which are mounted four watering nipples. The nipples' holes are set at varying angles, declining from nearly horizontal. A waste pipe and another nipple are provided. This nipple is almost vertical, and has a curved surface directly above the watering hole. This deviates the jet through approximately 90 deg. The vertical nipple is mounted roughly in the middle of the four other nipples. The nipples have a body with a passage and holes opposite the deflecting surface, which is provided both parallel and right angles to the nipples axis. |
