1、INTERNATIONAL STANDARD NORME INTERNATIONALE IS0 8909-I First edition Premiere ddition 1994-03-15 Forage harvesters - Part 1: Vocabulary Rkolteuses-hacheuses-chargeuses de fourrage - Partie 1: Vocabulaire - X qfgf = shear bar: Fixed plate provid- ing a stationary edge against which the cutterhead kni

The chopped crop is recut by the cutterhead knives as it passes through the sc

NOTE 8 The recutter screen is used primarily to reduce particle lengths that are substantially beyond the theoreti- cal length of cut. 4.7 smasher impact attachments: Protrusions attached either to the cutterhead knives or blower paddles, and/or to the cutterhead or blower housing band,

4、used primarily to break whole grains or maize corn kernels into smaller pieces either by impact or by shearing. 4.6 kernel cracking rolls: Driven pair of opposing, counter-rotating rolls placed in the chopped crop stream to crush whole grains or kernels into smaller pieces. 4.9 inertial chamber: Cha

6、their tips, pivotably attached to a rotor positioned trans- verse to the direction of travel and parallel to the ground. NOTE 9 The swath, windrow or standing crop is cut di- rectly by the flail blades into shorter random lengths by impact cutting or cutting against an adjustable element (stationary

IS0 8909-1:1994(E/F) 4.4.1 rotor cylindrjque: Couteaux months sur des dispositifs cylindriques de maniere que leurs tran- chants soient pratiquement paralleles a Iaxe de rotation. 4.4.2 rotor ir pales-couteaux: Couteaux mantes pratiquement radialement, dont l

NOTE 8 La grille de seconde coupe est principalement utilisee pour reduire la longueur des particules qui depassent nettement la longueur de coupe theorique. 4.7 accessoires de broyage par percussion: l%- ments en saillie fixes soit aux couteaux du rotor soit aux pales du ventilateur, et/au
