Abstract

La présente invention concerne une moissonneuse-batteuse grâce à laquelle les coûts de fabrication, par exemple, du travail de la tôle des pieds de support (71a, 71b) peuvent être réduits, et les pieds de support (71a, 71b) peuvent être rendus plus légers. Cette moissonneuse-batteuse est dotée de pieds de support gauche et droit (71a, 71b) ayant chacun une forme évasée dans laquelle la dimension de la largeur gauche-droite au niveau de l'extrémité inférieure augmente selon une vue dans la direction avant-arrière d'un corps de machine mobile (1), et les pieds de support auxiliaires gauche et droit (72a, 72b) se prolongeant le long des surfaces extérieures de la machine des pieds de support (71a, 71b). Des poutres de chenille gauche et droite (50) sont reliées au-dessous des côtés gauche et droit du corps de machine mobile (1) par l'intermédiaire des pieds de support gauche et droit (71a, 71b) et des pieds de support auxiliaires (72a, 72b), et les parties de déplacement gauche et droite (2) sont soutenues sur les poutres de chenille gauche et droite (50). Des supports de pieds de support (75) sont disposés sur les côtés de la surface supérieure des poutres de chenille (50), et les côtés d'extrémité inférieure des pieds de support (71a, 71b) sont intégralement fixés aux surfaces latérales des poutres de chenille (50) et aux surfaces latérales des supports de pieds de support (75). Les côtés d'extrémité inférieure des pieds de support auxiliaires (72a, 72b) sont intégralement liés par pression en surface aux surfaces supérieures plates des supports de pieds de support (75).
