Abstract

L'invention concerne une moissonneuse-batteuse conçue de telle sorte que, lorsqu'un dispositif de lame de récolte secondaire est soumis à une force de pression agissant depuis le côté avant, le dispositif de lame de récolte secondaire peut se rétracter vers l'arrière, et le mouvement de rétractation du dispositif de lame de récolte secondaire peut être amorti par un moyen d'amortissement, empêchant ainsi le dispositif de lame de récolte secondaire d'être endommagé. Les extrémités de base d'une paire de bras de support gauche et droit s'étendant vers l'avant et vers le bas sont portées de façon rotative sur le cadre de corps de machine d'un corps de machine mobile, par l'intermédiaire d'arbres de support de bras ayant des axes dirigés dans la direction gauche-droite. Un dispositif de lame de récolte secondaire est monté sur les extrémités avant des bras de support et entre celles-ci. Le dispositif de lame de récolte secondaire est porté par une section de récolte par l'intermédiaire d'un mécanisme de liaison/libération, est maintenu à une hauteur prédéterminée par rapport au sol et est ajusté de telle sorte que le dispositif de lame de récolte secondaire peut se rétracter vers l'arrière lorsqu'il est soumis à une force de pression agissant depuis le côté avant. Un moyen d'amortissement, pour amortir le mouvement de rétractation vers l'arrière de chacun des bras de support, est disposé derrière le bras de support.
