Abstract

L'invention vise à récupérer des épis de céréale sans sectionner d'autres parties des plants de céréales, à savoir les feuilles et les tiges, sur la base d'une prise des plants pour les entraîner vers le sol, en liaison avec leur passage simultané à travers une ouverture qui sépare les épis du reste des plants. Une unité récolteuse selon l'invention comporte au moins un couple de rouleaux cylindriques récolteurs (1a, 1b), d'axes parallèles (X'aXa, X'bXb) prolongés par une tête de réception (2a, 2b), les rouleaux (1a, 1b) présentant un écart (E1) qui définit une zone de passage (Z2). Les rouleaux (1a, 1b) présentent des nervures hélicoïdales (6a, 6b) de pas inversés et définissant des interstices (50) sensiblement fermés. De plus, des moyens d'entraînement en contre-rotation des rouleaux (1a, 1b) sont agencés dans un boitier (3). Une zone d'engrènement (Z3) dans une portion arrière (21a, 21b) des rouleaux (1a, 1b) présente des moyens (7a, 7b) de prise de tige (31) du plant (30) lors de cet entraînement.The invention aims to recover cereal ears without cutting other parts of the cereal plants, namely the leaves and stems, on the basis of a hold of the plants to drive them towards the ground, in connection with their passage. simultaneous through an opening that separates the ears from the rest of the plants. A harvesting unit according to the invention comprises at least one pair of cylindrical harvesting rollers (1a, 1b), of parallel axes (X'aXa, X'bXb) extended by a receiving head (2a, 2b), the rollers ( 1a, 1b) having a gap (E1) which defines a passage zone (Z2). The rollers (1a, 1b) have helical ribs (6a, 6b) of reverse pitch and defining substantially closed interstices (50). In addition, means for counter-rotating the rollers (1a, 1b) are arranged in a housing (3). A meshing zone (Z3) in a rear portion (21a, 21b) of the rollers (1a, 1b) has means (7a, 7b) for gripping the rod (31) of the plant (30) during this drive.
