[0039] like Figures 1 to 3 A high-stability and high-speed side sweeper suction and sweeping device is shown, comprising a connecting mechanism 1, a rocker mechanism 2, a suction and sweeping device 3, a side disk sweeping device 4 and a disk sweeping obstacle avoidance and shock absorption mechanism 5; the connecting mechanism 1 is connected to the chassis, and the connecting mechanism 1 is also connected to one end of the rocker mechanism 2, the other end of the rocker mechanism 2 is connected to the suction and sweeping device 3, a side disk sweeping mechanism 4 is provided on the suction and sweeping device 3 at one end close to the rocker mechanism 2, and a disk sweeping obstacle avoidance and shock absorption mechanism 5 is provided between the top of the side disk sweeping mechanism 4 and the suction and sweeping device 3; the present invention realizes the connection between the side suction and sweeping device and the driving vehicle through the connecting mechanism, realizes disk sweeping and suction sweeping of the ground through the suction and sweeping device and the side disk sweeping device, and ensures the safety and stability of the operation of the side suction and sweeping device of the sweeper through the rocker mechanism during disk sweeping.

As a preferred method, a baffle 3-6 is also provided at the suction port 3-5 in the present application. The baffle 3-6 is made of a rubber material with moderate hardness, so that the baffle 3-6 has a certain supporting force to prevent the garbage entering the suction port from falling out and ensure the suction and sweeping effect.
