Abstract
The utility model relates to a self-propelled negative pressure dust absorption flexible shaft sweeper of pneumatic hose at tail end of a central air-conditioning. The front end of a dust absorption pipe is provided with two independent spiral hair brushes which has a coarse pitch adaptive to the diameter of an air duct, and a forward and a reverse rotating direction. A soft shaft machine steel axle drives the two spiral hair brushes to be synchronously rotated, the rotating direction is reverse, the reverse turning distances are mutually counterbalanced, thus eliminating damageable centrifugal force, stabilizing the brush head and overcoming defects that in the single cleaning hair brush structure of the traditional soft shaft cleaning machine, the reverse torque easily causes the tail end soft air pipe to be twisted into rough flower shape and torn. When the spiral hair brush is embedded in the tail end spring-shaped pipe wall to rotate, certain axial displacement force is generated, and the brush air opens the crapy air pipe, thus conducting continuous compound type sweeping in a row-brush type, without clearances. A negative pressure cavity formed between a block plate and the air-sealing annular bush becomes a high-efficiency energy-saving dust collecting space. A portable industrial dust absorption machine is qualified. Therefore, the self-propelled negative pressure dust absorption flexible shaft sweeper adapts to the characteristics of low self strength, complicated turning angles, and narrow operation space at the located position.
