Specific embodiment
In order to deepen the understanding to the utility model, the utility model is done further below in conjunction with drawings and examples
Detailed description.
Referring to attached drawing 1, the utility model proposes a kind of profiling grass trimmer rotary cutters, including are mounted on cutterhead 7
Blade 11, the blade 11 is mounted on cutterhead 7 by edge bearing 12, rotated around 12 axis of edge bearing；7 center of cutterhead is equipped with
Installation axle 7-1 is successively cased with position-arresting disk 4, attachment base 2 and motor 1,4 outer diameter of position-arresting disk in the top of the installation axle 7-1
Greater than 11 rotating diameter of blade, the motor 1 is that cutterhead 7 provides rotary power.Upper bearing (metal) is equipped between position-arresting disk 4 and attachment base 2
3.Retaining ring 6 and bushing 7 are equipped between position-arresting disk 4 and cutterhead 7.Cutterhead 7 is driven by motor 1, is rotated, and blade 11 is revolved in high speed
Cutting operation is completed in turning.
Connector sleeve 9 and slide plate 10 are successively cased with below installation axle 7-1, the slide plate is supported in ground at work.Even
Lower bearing 8 is equipped between female connector 9 and installation axle 7-1, slide plate 10.Slide plate 10 is concaved among 4 bottom of position-arresting disk in bowl-shape
It falls into, recess is adapted with 10 top of slide plate.Position-arresting disk 4 is mounted on the outer tube of attachment base 2, can be freely rotated, and
