PURPOSE:To agitate and mix soil uniformly by disposing nonrotational blade while adjoining it to the rotary blade of the title agitator mixing a coagulant into the ultra-soft ground swamp, marshland, etc. and shearing and crushing soil stuck to an agitating blade. CONSTITUTION:Agitating blades 151..., 151'... are fixed to hollow shafts 131... through annular bodies 141..., 141'..., and fixed blades 17..., 17'... are axially supported rotatably to the hollow agitating shafts 131... through spacers 161..., 161'.... Consequently, since the fixed blades 17..., 17'... are not turned even when the agitating blades 151..., 151'... are rotated, soil, which is stuck around the agitating bldes 151..., 151'... and turns together with the blades, is shorn and broken and crushed by means of the agitating blades 151..., 151'... and the fixed blades 17..., 17'..., and the soil is fractionated. Accordingly, the agitation of soil and mixing with a milky coagulant injected through ejecting holes 19 are conducted uniformly. |
