Homogenizing plate device for salt mist box and accumulated salt cleaning method thereof

The present invention discloses a homogenizing plate device for a salt mist box. The device comprises the salt mist box, a homogenizing plate mechanism and an accumulated salt cleaning mechanism, the homogenizing plate mechanism comprises a homogenizing plate, the homogenizing plate is located in the salt mist box and divides the salt mist box into an upper cavity and a lower cavity, the accumulated salt cleaning mechanism comprises a scraper, the scraper is located in the upper cavity of the salt mist box, and the blade of the scraper is tightly contacted with the upper surface of the homogenizing plate. The scraper moves along the homogenizing plate to clean accumulated salt on the homogenizing plate, so that the problem that the salt spray performance test stability is influenced due to the fact that the accumulated salt blocks homogenizing plate holes in the long-term operation process of the salt spray box is solved, the frequency of manually cleaning the accumulated salt is reduced, the equipment utiliz
