Abstract

See full text

A blowing-suction machine includes a casing, a suction duct arranged at the front portion of the casing. It further includes a motor and a shredder mechanism that are arranged in the casing in order from rear to front. The front end of the shredder mechanism is connected to the rear end of the suction duct. The shredder mechanism includes blades and a cutting assembly that are arranged in order from rear to front. The blades are arranged on an output shaft of the motor. The cutting assembly is arranged at a rear end of the suction duct for shredding fallen leaves. The cutter cooperates with the secondary cutter such that fallen leaves and rigid trashes can be effectively shredded by the blowing-suction machine. Fallen leaves can be effectively separated from air via the collecting cartridge and the filtering unit, such that the amount of the collected leaves is effectively increased.
