Surface coupling agent uniform spraying mechanism for TOFD detection

The utility model belongs to the technical field of TOFD (time of flight diffraction) detection, and particularly relates to a surface coupling agent uniform spraying mechanism for TOFD detection, which comprises a spraying machine with a coupling agent spraying function, and a driving device is mounted on the surface of the spraying machine. According to the surface coupling agent uniform spraying mechanism for TOFD detection, the protection device is arranged on the surface of the spraying machine, a baffle in the protection device is used for shielding the lower end of the spraying machine, external factors are prevented from interfering use of the spraying machine, meanwhile, a coupling agent with an overlarge spraying angle is collected and adhered, and the spraying efficiency is improved. Meanwhile, by means of the design that holes are formed in the surface of the baffle in a directional mode, the effect of reducing the surface wind resistance of the baffle is achieved, meanwhile, airflow is discharged
