<p><P>PROBLEM TO BE SOLVED: To provide a threshing machine that carries out a threshing operation corresponding to a type and field conditions and intends to harmonize improvement in separation precision of grain with reduction in grain amount (loss amount) unloaded together with dust. <P>SOLUTION: The threshing machine includes a volume switch for selecting one function from a plurality of functions indicating the relationship between the velocity of the combine harvester and a fin angle to be secured at the very least in which a user operates the volume switch and selects one function corresponding to a type and field conditions. The threshing machine has a constitution that a rotary lever 52 is operated on the basis of the velocity of a combine harvester in reference to the selected function, a fin angle r is adjusted and the action of a shutter 57 for opening and closing an air inlet 55 is adjusted. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
