Claims

[Scope of utility model registration request]

The rotor 12 is rotatably attached to a rotor shaft 13, and a liquid injection pipe 19 extending radially from the rotor and whose tip can penetrate into the soil is attached, and a liquid injection tube 19 is attached to the outer peripheral surface of the rotor shaft. A check valve 25 is arranged at the inner end of the liquid injection pipe close to the circumferential groove, and an opening/closing member 32 of the check valve is inserted into the circumferential groove. A cam protrusion piece 3 is made to protrude inward and is provided in the circumferential groove.
3 is removably attached, and during rotation of the rotor and the liquid injection pipe, the opening/closing member of the check valve engages with the cam protrusion to open the check valve;
A soil injection machine, characterized in that the liquid in the circumferential groove is delivered to the liquid injection pipe, and the delivered liquid is injected into the soil from the tip of the liquid injection pipe.
