目前，国产喷浆机按转子的结构形式分，主要有U型料腔和直通料腔两大类。所谓‘刀”型料腔就是转子的料腔形状如同英文字母“U”．风从上口进入转子料腔，料也从上口通过弯头吹出；而直通料腔则是转子料腔形状如一个直简，风从上口进入转子料腔，料从下口吹出。“U”型料腔喷浆 At present, the domestic shotcrete machine according to the structure of the rotor points, there are U-shaped cavity and straight through the cavity two categories. The so-called ’knife’ type material cavity is the rotor cavity shape as the English letter ’U’ wind from the mouth into the rotor material cavity, material from the mouth through the elbow blowing; and through the material cavity is the rotor cavity shape A straightforward, wind from the mouth into the rotor cavity, expected to blow out from the mouth. “U” type cavity shotcrete
