Abstract
A lawn mower includes a housing with a baffle that defines an air path to produce a cross-flow. The baffle includes a vent to manipulate air pressures within the housing and facilitate movement of plant clippings. A hand-held device for trimming with a rotary blade assembly may also include a housing that defines an air path to produce a cross-flow. The hand-held trimming device may also a baffle with a vent to facilitate movement of plant clippings.
Claims20
A rotary blade assembly housing configure to produce a cross-flow from an input opening to an output opening, the housing comprising:
- a baffle defining a vent between a tongue surface and an exterior surface proximal to a surface to be cut by the rotary blade assembly,
- wherein the vent is configured to alter the cross-flow to prevent plant clippings from adhering to one or more internal surfaces of the housing.
A plant trimming device comprising:
- a horizontal rotary blade assembly having:
- a plurality of rotors;
- and
- a plurality of blades, each of the plurality of blades connected to each of the plurality of rotors, each of the plurality of blades forming an airfoil with a cutting edge;
- and
- a blade assembly housing defining an input opening and an output opening, the housing substantially surrounding at least a portion of the horizontal rotary blade assembly, and the housing defining a path configured to produce a cross-flow when the horizontal rotary blade assembly rotates at an operational speed.
A mowing device comprising:
- a horizontal rotary blade assembly having:
- a plurality of rotors;
- and
- a plurality of blades, each of the plurality of blades connected to each of the plurality of rotors, each of the plurality of blades forming an airfoil with a cutting edge;
- a mower housing defining an input opening and an output opening, the housing substantially surrounding at least a portion of the horizontal rotary blade assembly, and the housing defining a path configured to produce a cross-flow when the horizontal rotary blade assembly rotates at an operational speed;
- and
- a baffle dividing the input opening and output opening, the baffle defining a vent.
