The utility model relates to the field of cleaning mechanical equipment for sweeping objects falling to the ground and garbage on a road surface, in particular to a swinging brush for sweeping waste on the road surface. A suspension plate and all mechanisms are mounted on a motor vehicle in a suspended mode, an arrangement plate is connected with the suspension plate, a swinging beam is connected with the arrangement plate through a swinging beam base, the other end of the swinging beam is connected with a vertical shaft sleeve through a butting plate, a vertical rod, the butting plate and the vertical shaft sleeve form an integrity, and a vertical shaft and the swinging brush form an integrity. One end of an eccentric connecting rod is connected with an eccentric wheel, and the other end of the eccentric connecting rod is connected with the swinging beam. When the motor vehicle carries the cleaning mechanical equipment in a suspended mode to operate, a motor is started, the motor drives the swinging beam and the swinging brush to do left-right swinging operation through the eccentric wheel and the eccentric connecting rod, and therefore the objects falling to the ground and the garbage on the road surface can be thoroughly cleaned up.
