Abstract

The straw is dropped from the end of the harvester down onto the chopper. This has a rotating cutter (3) and a fixed blade (9), with the straw being chopped to a set length. The straw is guided to the chopping position by angled plates (8) each side of the fixed blade. The fixed blade is horizontal and is clamped between the angled guides. The rotating blades, the fixed blade and the guides cover the whole width of the harvester output.

Description

Moissonneuse-batteuse avec hacheuse raortée.  Combine harvester with a cutter.

La présente invention concerne une moissonneusebatteuse avec hacheuse rapportée au voisinage du capot de sortie de la paille, dont les couteaux rotatifs coopèrent avec des contre-lames fixes. The present invention relates to a combine harvester with a chopper attached in the vicinity of the straw outlet hood, the rotary knives of which cooperate with fixed counterblades.

Le but de l'invention est d'élaborer une hacheuse sous une forme telle que la qualité du produit coupé, en particulier de la paille, surtout du point de vue de la longueur de hachage, soit optimisée. The object of the invention is to develop a chopper in a form such that the quality of the cut product, in particular of the straw, especially from the point of view of the length of chop, is optimized.

Conformément à l'invention, ce but est atteint dans une moissonneuse-batteuse du type défini au début, caractérisée en ce que, eu égard à la direction de la rotation des couteaux, est disposée, avant l'emplacement de coupe entre les couteaux rotatifs et fixes, une arête de battage qui s'étend selon la largeur du capot de sortie de la paille, en soi connue dans les hacheuses stationnaires et s'étendant parallèlement à l'axe de l'arbre des couteaux, cette arête se projetant dans le trajet du produit à couper, et étant pourvue d'un couteau supplémentaire fixe s'étendant également selon la largeur du capot de sortie de la paille, et qui constitue le bec de l'arête de battage. According to the invention, this object is achieved in a combine of the type defined at the start, characterized in that, having regard to the direction of rotation of the knives, is arranged, before the cutting location between the rotary knives and fixed, a threshing edge which extends along the width of the straw outlet cover, known per se in stationary choppers and extending parallel to the axis of the knife shaft, this edge projecting into the path of the product to be cut, and being provided with a fixed additional knife also extending along the width of the straw outlet cover, and which constitutes the beak of the threshing edge.

Un mode d'exécution de l'invention va maintenant être décrit à titre d'exemple nullement limitatif, avec référence aux figures du dessin annexé dans lequel
- la figure 1 représente en vue latérale simplifiée une moissonneuse-batteuse à hacheuse rapportée
- la figure 2 représente l'extrémité de secouage de la machine, et montre les caractéristiques de détail de la hacheuse, selon une vue latérale également schématique ; et
- la figure 3 représente à plus grande échelle, en vue latérale et en coupe, les caractéristiques essentielles de l'invention.
An embodiment of the invention will now be described by way of non-limiting example, with reference to the figures of the accompanying drawing in which
- Figure 1 shows a simplified side view of an attached chopper combine
- Figure 2 shows the shaking end of the machine, and shows the detail characteristics of the chopper, in a side view also schematic; and
- Figure 3 shows on a larger scale, in side view and in section, the essential characteristics of the invention.

En 1 on a désigné une moissonneuse-batteuse sous le capot de sortie de paille 2 de laquelle est disposée une hacheuse rapportée 3 dont les couteaux 4 tournant dans le sens de la flèche A coopèrent avec des contre-lames fixes 5. Les secoueurs de la machine sont désignés par la référence 6, les extrémités de secouage se situant au voisinage d'une tôle 7 de chute de la paille, qui assure le transfert de la paille à la hacheuse 3, cette tôle s'étendant selon la largeur du capot de sortie de paille 2. In 1 we have designated a combine harvester under the straw outlet hood 2 of which is disposed an attached chopper 3 whose knives 4 rotating in the direction of the arrow A cooperate with fixed counterblades 5. The agitators of the machine are designated by the reference 6, the shaking ends being located in the vicinity of a sheet 7 for falling straw, which ensures the transfer of the straw to the chopper 3, this sheet extending along the width of the hood of straw outlet 2.

Eu égard à la direction de déplacement des couteaux, est prévue, devant l'emplacement de coupe entre les couteaux rotatifs 4 et fixes 5, une arête de battage 8 s'étendant parallèlement à l'arbre 4' des couteaux. With regard to the direction of movement of the knives, there is provided, in front of the cutting location between the rotary and fixed knives 4, a threshing edge 8 extending parallel to the shaft 4 'of the knives.

Cette arête est constituée par la fixation, sur la tôle de chute 7, de deux profilés creux 8',8" qui ont une section transversale triangulaire et qui s'étendent aussi selon la largeur du capot 2 de sortie de la paille. Entre les deux profilés creux 8',8" est enserré un couteau supplémentaire 9 dont la position est réglable, la liaison étant effectuée par un système vis-écrou 10.This edge is constituted by the fixing, on the drop sheet 7, of two hollow sections 8 ', 8 "which have a triangular cross section and which also extend along the width of the cover 2 for straw outlet. two hollow sections 8 ′, 8 "are enclosed an additional knife 9 whose position is adjustable, the connection being effected by a screw-nut system 10.

Comme il va de soi et comme il résulte d'ailleurs déjà de ce qui précède, l'invention ne se limite nullement- à ceux de ses modes d'application et de réalisation qui ont été plus particulièrement envisagés elle en embrasse, au contraire, toutes les variantes.  As goes without saying and as it moreover already results from the foregoing, the invention is in no way limited to those of its modes of application and embodiments which have been more particularly envisaged, it embraces it, on the contrary, all variants.
