[0019] When in use, first connect the lifting arm assembly 1 to the front frame of the sweeper, and then fix the quick-change bracket and the lifting arm assembly through the two ball head locking pins 10 on the left and right sides to complete the structural assembly work. Through the setting of the caster adjustment device 9, it mainly plays a role in buffering with the ground and lowering the quick-change bracket assembly after the brush is worn out after a period of use to control the contact distance between the front brush and the ground. Two hydraulic motors 1 4 provide power to the rear brush assembly 2 and two hydraulic motors 2 5 provide power to the front brush assembly 3, so that the rear brush assembly 2 and the front brush assembly To complete the cleaning action, during the cleaning process, the rear brush assembly 2 and the front brush assembly 3 on the left side rotate clockwise, and the rear brush assembly 2 and the front brush assembly 3 on the right side rotate counterclockwise, so as to prevent the cleaned objects from being thrown outward. A nozzle is installed on the nozzle bracket assembly 6 to reduce dust. The front end swing arm assembly 13 and the left and right mounting bracket assemblies 11 are composed of two rotating devices in the front and back. The upper and lower and left and right inclination angles of the front brush assembly 3 in contact with the ground are adjusted by the swing arm telescopic device 7 as needed.
