The rotation of the two sets of first rotating shafts (6) drives the first transmission belt (5) to transmit. The up and down transmission of the first transmission belt (5) drives the moving plate (7) to move. The start-up of the second servo motor (11) drives the second rotating shaft (12) to rotate. The rotation of the second rotating shaft (12) drives the second transmission belt (14) to move in a circular motion in the horizontal direction. S2: When the facade of the rural building needs to be maintained, the transmission of the second transmission belt (14) drives the fan (17) to move, and the start of the fan (17) blows the droplets sprayed by the nozzle (23) to disperse along the inner side of the guide plate (22), and the droplets come into contact with the facade of the rural building; S3: When a portion of the exterior wall needs to be maintained, when the buffer plate (26) moves, the first spring (24) and the second spring (25) will buffer the buffer plate (26), the sensor strip (27) will scan the exterior facade of the building, and the strip nozzle (28) will maintain the exterior facade of the building.
