Abstract
Description
Technical Field

[0002] In a full-feed combine harvester, crops are cut by a cutterbar cutting device and fed into a threshing and separating device through a feeding device for threshing and separation. The straw is shredded by a shredder behind the threshing cylinder and then scattered onto the cut field. The grain mixture is cleaned by a cleaning device. The clean grains are conveyed to a grain tank through a grain auger, and the unthreshed residues are returned to a cleaning sieve through a residue re-threshing auger for secondary cleaning. On the combine harvester, the power of various devices comes from the engine and drives the corresponding devices to work through various transmission mechanisms.
