Air-material mixing and spraying actuator with an application method thereof

An air-material mixing and spraying actuator, comprising:

• a material mixing and spraying pipe, and a material discharge outlet being provided at one end thereof;
• a material temporary storage assembly disposed at one end of the material mixing and spraying pipe away from the material discharge outlet and configured to temporarily store materials;
• a second material supply assembly communicating with the material temporary storage assembly and configured to send the material to the material temporary storage assembly;
• and
• a compressed air supply assembly communicating with the material temporary storage assembly and configured to provide high-pressure air that bursts the soil to form cracks or achieve an uplift effect, and simultaneously spray the material temporarily stored in the material temporary storage assembly to the cracks in cooperation with the material temporary storage assembly,
• wherein the compressed air supply assembly is a pneumatic shock wave generator;
• and the material temporary storage assembly comprises a shell and a rotating core, wherein the shell is disposed at the material mixing and spraying pipe and is provided with a first straight-through hole, a second straight-through hole and a third straight-through hole which communicate with the material mixing and spraying pipe, the second material supply assembly, and the compressed air supply assembly respectively;
• the rotating core is rotatably disposed in an inner cavity of the shell, has a temporary storage cavity, and is provided with a first central hole and a second central hole which communicate with the temporary storage cavity, and the central axes of the first central hole and the second central hole coincide with each other;
• and
• during the rotation of the rotating core, the temporary storage cavity is configured to communicate with the first straight-through hole, the second straight-through hole and the third straight-through hole through the first central hole and the second central hole.
