The invention discloses a spraying device for
agricultural irrigation. The spraying device comprises a base and a communicating pipeline, the base is fixedly installed on the ground, a
water pipe is fixedly installed on the base, the two ends of the communicating pipeline are fixedly connected to the
water pipe and a spray head correspondingly, and the interiors of the
water pipe and the spray head which are connected with the communicating pipeline are communicated through the communicating pipeline; and an adjusting mechanism acting on
irrigation water is installed on the spray head, and a driving mechanism acting on the adjusting mechanism is installed on the communicating pipeline. According to the spraying device for
agricultural irrigation, through the adjusting mechanism, the spraying range of the
irrigation water can be automatically and circularly adjusted, so that the area where the
irrigation water is sprayed is not limited to a certain area, and the irrigation area is greatly improved; meanwhile, the adjusting mechanism is driven by water power, so that the energy-saving effect is achieved; and according to the spraying device, a water dispersing frame is fixedly installed in a through hole in a movable block, the
irrigation water sprayed out of the spray head is in a scattered state, and therefore it is guaranteed that the spraying efficiency is optimal.
