Patent

CA 2634124

A lawn mower has a scroll portion for allowing grass clippings to swirl within a housing while guiding them to a grass discharge passage. A guide provided beneath a top plate of the housing is placed along the scroll portion. A rear guide end of the guide is opposed to a passage opening facing the housing of the grass discharge passage. The direction of a swirling flow is gradually changed and guided toward the passage opening by the guide. A pivotal shutter pivotal about a generally vertical axis is provided for opening and closing the grass discharge passage.

L'invention concerne une tondeuse à gazon qui comporte une partie spiralée pour permettre aux tontes de pelouse de tourbillonner dans un logement, tout en les guidant vers un passage de décharge de pelouse. Un guide situé sous une plaque supérieure du logement est placé le long de la partie spiralée. Une extrémité arrière du guide est en regard de l'ouverture de passage en face du logement du passage de décharge de pelouse. La direction d'un écoulement en vortex est graduellement modifiée et guidée vers l'ouverture du passage par le guide. Un volet rotatoire qui tourne autour d'un axe généralement vertical est prévu pour l'ouverture et la fermeture du passage de décharge de pelouse.
