Wind-cooling heat dissipating fan is additionally provided on rear side of the power fan, wind-cooling heat dissipating fan rotates air draught, makes air-flow by air inlet
Enter at grid.
The shaft flows to arrangement along the air inlet of air-inlet grille.
The air-inlet grille opens up as circle, and cooperates and be equipped with dust-proof gauze, and shaft passes through the center of circle cloth of air-inlet grille
If.
The hairbrush is constituted by hairbrush pressing plate and towards the bristle that air-inlet grille is laid, and bristle is fixed with hairbrush pressing plate
Connection.
The shaft is rotatablely connected by bearing and dust cover, and bearing is fixedly mounted at dust cover.
The dust cover is detachably connected and is formed by the first dust cover and the second dust cover, and power fan is placed in first and prevents
In dust hood, air-inlet grille is opened on the front end face of the second dust cover.
The length of the hairbrush and air-inlet grille equal diameter are arranged, and shaft pass through air-inlet grille the center of circle and with hairbrush
Midpoint connection.
The hairbrush is fixedly connected by the nut being arranged with shaft.
The beneficial effects of the utility model are:
1) the active self-cleaning device, it is air-cooled to dissipate when grass trimmer works by the setting of active self-cleaning device and dust cover
Hot-air fan rotates air draught, and air-flow flows to engine direction by air inlet, and then drives the active self-cleaning device rotation in dust cover,
And the rotation speed of active self-cleaning device is directly proportional to engine speed, so that the cleaning speed of hairbrush and active self-cleaning device are protected
Synchronization is held, guarantees no longer to lead to lawn mower engine cabin high temperature since careless foam, dust are inhaled into when mower grass operation；
2) the active self-cleaning device can quick folding, thoroughly improve mowing machine operation when, because careless dustiness dye caused by start
The damage of machine high temperature, extends the service life of grass trimmer.
