Abstract: A percussive sprinkler with adjustable discharge angle has a pedestal, adjusting ring, main body, percussion guide frame and sprinkler head driving rod. The percussive sprinkler is characterized by that, the height of the spacing for the driving rod retaining surface of the adjusting ring can be adjusted via an adjustor, such that the second end on the sprinkler head driving rod connected to the sprinkler head is abutted onto the driving rod retaining surface. When the main body of the percussive sprinkler is rotated, the sprinkler head driving rod will shift vertically along the circumferential path on the driving rod retaining surface, so the sprinkler head is driven to swing vertically with change of the discharge angle. In such a case, spray with different sprinkling distance can be generated by the sprinkler head, thus making up the shortcomings for more uniform sprinkling coverage with higher flexibility and applicability.
