Abstract

La présente invention concerne une lame de vis sans fin et une déneigeuse équipée de cette lame de vis sans fin. Cette lame de vis sans fin peut, tout conservant à un niveau satisfaisant son rendement élevé de fraisage de la neige, amortir un choc s'appliquant au corps de la déneigeuse lors du démarrage et pendant le fonctionnement en déneigement. En outre, même en cas d'abrasion ou d'endommagement du bord de coupe de la lame de vis sans fin, il n'y a pas besoin de remplacer la totalité de la lame de vis sans fin. La déneigeuse (1) comporte un dispositif de vis sans fin (10) pourvu d'une lame de vis sans fin (20). La lame de vis sans fin (20) est constituée d'une part d'un corps de lame (22) fait d'un matériau élastique capable d'absorber un choc se produisant pendant le fraisage de la neige, et d'autre part de bords de coupe (24) fixés sur le corps de lame (22) de façon à pouvoir être remplacés.
