Specifically, a rotating ring may be further disposed on the irrigation pipe 10, and the rotating ring is rotatably disposed inside the first housing, so that the rotation of the irrigation pipe 10 is restricted, and the occurrence of an offset in the rotation of the irrigation pipe 10 is avoided.

From the above description, it can be seen that the above embodiments of the present utility model achieve the following technical effects:

the irrigation apparatus of the present utility model comprises an irrigation mechanism comprising an irrigation pipe 10, a spray head assembly 20 and a control valve. The amount of irrigation liquid required in summer is increased, and the first spray head 21 can not meet the irrigation requirement by spraying alone, so that when irrigation is performed in summer, the control valve controls the second spray head 22 to be opened, and the first spray head 21 and the second spray head 22 spray simultaneously, so that the irrigation effect is improved; in other seasons, the first spray head 21 is independently sprayed to meet the irrigation requirement, the control valve controls the second spray head 22 to be closed, and at the moment, the first spray head 21 is only used for spraying irrigation, so that the first spray head 21 and the second spray head 22 are matched with each other, water can be saved, different modes of irrigation can be carried out on crops in different seasons and different growth periods, and the irrigation efficiency is improved.
