To provide a mixing device of a soil improving machine capable of suppressing catching of a foreign matter in agitating blades.
The mixing device 19 of the soil improving machine includes: a casing 71 having a soil inlet port 74 arranged on an upper part on one side in the longitudinal direction and an outlet port 75 arranged on a lower part on the other side; a rotary shaft 76 longitudinally extending inside the casing 71; agitating blades 77 arranged on an outer periphery of the rotary shaft 76 and on a spiral locus, and fan-shaped connecting plates 78 mutually connecting the agitating blades 77 which are adjacently arranged on the spiral locus. Each of the connecting plates 78 is formed to have at least two planes having different angles to the rotary shaft 76 seen from the radial direction of the rotary shaft 76, and to have the smaller height in a radial-direction of the rotary shaft 76 than that of the agitating blades 77.
