Abstract
(EN)
The present invention relates to a seed sowing apparatus which includes a substantially flat circular disc (1) mounted on a frame so as to be rotatable about horizontal axis (2) while partly embedded in soil (3) and drawn in a forward direction substantially parallel to the soil surface and substantially perpendicular to a disc axle. The apparatus also includes at least one blade (10) having a leading edge (11) defined by the intersection of two opposite side surfaces and a means (41, 45) for mounting said blades on said apparatus so that said leading edge (11) is held close to or in intimate contact with said disc (1), wherein said at least one blade's leading edge (11) is inclined in a plane of said blade such that an angle of the leading edge (11) with respect to an arc (A, B, C) of the disc surface passing beneath the leading edge (11) is zero or positive over the entire length of the leading edge (11).
(FR)
L'invention concerne un semoir comprenant un disque circulaire (1) sensiblement plat monté sur un support de manière à pouvoir tourner autour d'un axe horizontal (2) lorsqu'il est partiellement enfoncé dans le sol (3) et entraîné vers l'avant dans une direction sensiblement parallèle à la surface du sol et sensiblement parallèle à l'axe du disque. Ce dispositif comprend en outre au moins une lame (10) dont le bord d'attaque (11) est défini par l'intersection des deux surfaces latérales opposées et des moyens (41, 45) permettant de monter ces lames sur le dispositif de telle manière que ledit bord d'attaque (11) est maintenu à proximité du disque (1) ou en étroit contact avec ce dernier, et le bord d'attaque (11) d'au moins une lame est incliné dans le plan de la lame de telle manière que l'angle entre le bord d'attaque (11) et un arc (A, B, C) de la surface du disque passant sous le bord d'attaque (11) est supérieur ou égal à zéro sur toute la longueur du bord d'attaque (11).
