发明名称 Cutterhead for a portable handheld brushcutter
摘要 The invention is directed to a cutterhead for a portable handheld brushcutter for cutting grass, weeds and the like. The cutterhead includes a housing which holds a spool for the cutting filament. Two spool chambers are formed on the periphery of the spool by a radial partition wall. A cutting filament is wound in each of the spool chambers and each of the cutting filaments is assigned an exit opening in the housing which extends into free space. The partition wall lies at the same axial elevation with the exit openings. The partition wall is provided with at least one lead-in channel through which the filament is guided into the interior of the spool when inserted. A reliable introduction of the filament is provided by a simple configuration of the cutterhead and makes a reliable wind-up and pay-out of the filament possible. This is achieved by providing a lead-in channel for each spool chamber with the entrance of the lead-in channel being defined by an insert funnel. The insert funnel is provided on each of the sides of the partition wall with a filament guide. Each side faces toward the assigned spool chamber. Furthermore, the lead-in channel extends non-linearly in the spool.
