CA 2216539

A portable hand-held concrete, mortar and gypsum mixer comprises a small gasoline powered implement having a drive shaft (16) extending generally downward from the handles (18) to a gear box (22). A transverse shaft (24) driven by the driven shaft extends to either side of the gear box (22). Mounted on the transverse shaft are a plurality of blades (26, 28) shaped to thoroughly agitate and mix a combination of water and the ingredients for concrete, mortar, gypsum or similar heavy, hard to mix materials. Surrounding the blades are thin rings (34) attached to the blades to form a round circumferential surface about the blades and thereby prevent the blades from directly contacting the mixing trough or other means of containing the mix. In the alternative, the plurality of blades may be shaped at their peripheries to form substantially continuous circular circumferences.

L'invention concerne une mélangeuse à main portable, pour béton, mortier et plâtre qui se compose d'un petit moteur à essence monté sur un guidon (18) et se prolongeant vers le bas par un arbre moteur (16) relié à une boîte de vitesse (22) et, de part et d'autre de cette dernière un arbre transversal (24) entraîné par l'arbre à moteur. L'arbre transversal est équipé de plusieurs lames (26, 28) conçues pour parfaitement agiter et malaxer l'eau et les ingrédients nécessaires à la confection de béton, de mortier, de plâtre ou de tout autre matériau lourd et difficile à mélanger. Les extrémités des lames sont reliées par une fine tige (34) formant un cercle autour d'elles pour les empêcher de venir taper contre les bords de l'auge de mélangeage ou de tout autre récipient. Les lames peuvent aussi être façonnées de telle sorte que leurs extrémités forment un cercle sensiblement continu.
