Its technical points are: starting the motor, so that the rotating shaft drives the cleaning plate to scrape and clean the bottom plate of the main body, moving the baffle, so that the dirt scraped by the cleaning plate leaves the inside of the main body through the sewage outlet, the collection box can collect the cleaned dirt, the scraper can prevent the dirt from contaminating the slide groove inside the main body corresponding to the baffle when the baffle moves, the chassis can protect the motor, and the heat dissipation holes can facilitate the heat dissipation of the motor.

[0004] However, similar to the above-mentioned exhaust dust removal equipment for paint production, the dirt is cleaned by the friction between the cleaning plate and the bottom plate of the main body. However, when the dirt is cleaned by the cleaning plate, the dirt will adhere to the cleaning plate. The dirt on the cleaning plate will increase with the increase of time. Therefore, it is necessary to propose a new solution to solve this problem. Utility Model Content

[0014] 1. The utility model limits the position of the supporting shaft by a fixed frame, and drives the rotating shaft to rise by a hydraulic telescopic rod. When the rotating shaft rises, the scraper is driven to move accordingly, so that the scraper is separated from the main body. Subsequently, the bevel gear one component, the bevel gear two and the connecting shaft cooperate with each other to adjust the rotation of the bevel gear one component, so that the scraper follows the rotation, and the different surfaces of the scraper are directed toward the bottom of the main body, and the hydraulic telescopic rod is reversely controlled to reset the scraper position, so that the scraper can remove the dirt on the main body while cleaning itself.
