The invention discloses a chiseling machine for a tunnel top surface layer with airflow mutual-contacting and anti-splashing. The structure of chiseling machine for the tunnel top surface layer with airflow mutual-contacting and anti-splashing comprises: a chiseling device, a driving host, a moving wheel, a hand push rod and an operation switch. The chiseling machine for the tunnel top surface layer with airflow mutual-contacting and anti-splashing has the beneficial effects that the chiseling head arranged on the attack mechanism can rotate independently, so that larger stones are subjected to rotary crushing, the surrounding soil layers are not influenced, the chiseling head is prevented from generating large impact force when being contacted with the stones due to the fixed structure, the reinforced concrete protective layer at the periphery of the chiseling head is damaged, airflow generated by fast rotation of the rotating rod is collected and utilized by utilizing the aerodynamicprinciple, the airflow p
