Spraying head

The utility model discloses an injector head, which relates to the field of subway construction, solves the problem that pea gravels are unevenly distributed when gaps of pipe pieces are filled with the pea gravels, and is characterized in that the injector head is used for injecting the pea gravels and comprises a bent spray head; and the bent spray head can enable an included angle between the ejection direction of the pea gravels and the movement direction of the pea gravels in the spray head to be 0-90 degrees. The purpose of preventing pea gravel from being deposited is achieved. 本实用新型公开了一种喷射头，涉及地铁施工领域，解决了豆砾石填充管片缝隙时分布不均的问题，其技术方案要点是：一种喷射头，用于豆砾石喷射，所述喷射头包括喷头，所述喷头呈弯折状；所述弯折状的喷头可以使豆砾石射出方向与其在喷射头内运动方向的夹角呈0～90度。达到避免豆砾石淤积的目的。
