The utility model relates to a telescopic explosive bead forming dripper, the lower extreme of the top seat has an oil injection part which is distributed along the vertical direction and is narrowed into a column shape, the oil injection part has an
essential oil channel which is communicated with the oil injection hole on the side surface of the top seat and has an outlet which penetrates the lower end surface, a glue liquid cavity is arranged on the upper end surface of the base, an injection hole which is communicated with the glue liquid cavity is arranged on the side surface of the base, a concentric flow column channel which penetrates the lower end surface of the base is arranged on the cavity bottom of the glue liquid cavity, the lower end of the oil injection part enters the glue liquid cavity and the outlet of the
essential oil channel is opposite to the inlet of the concentric flow column channel, the top seat and the base are connected by the adjusting mechanism which adjusts the position of the outlet of the concentric flow column channel from top to bottom. Advantageous effects: the top seat and the base are connected by introducing the adjusting mechanism, and the position of the outlet of the concentric flow column channel is adjusted from top to bottom, so that the dripper can be matched with the overflow device without changing the
height difference between them, a
single variable is controlled, and the equipment is quickly debugged.
