PURPOSE: A sweeping machine is provided to effectively do painting or grinding work while minimizing the damage of a sweeping wheel even when a working surface is uneven or curved. CONSTITUTION: A sweeping machine comprises a frame (12), a rotary plate (14), an upper plate (15) and a wheel supporter (16). The upper plate is connected to the rotary plate and is equipped with an actuator (1) to rotate the rotary plate. The upper plate is coupled on the upper side of the frame. The wheel supporter is fixed on the rotary plate and is arranged in the direction of a working surface through a hollow of the frame and supports a sweeping wheel (2) in order to contact the work surface. The wheel supporter is rotated with the rotation of the rotary plate and multiple sweeping wheels can be coupled for use. [Reference numerals] (AA) Work plane |
