Separator for combine harvester - has overhead conveyor in possible alternative forms with closed cover located between separator and precipitator

摘要

The separator aggregate has an overhead conveyor (46,46a) with a closed cover which is smooth but with a coat of highly abrasive material. There are several forms of the cover, one of which consists of a series of open pockets around the perimeter. Another form has small openings at intervals around the perimeter large enough to let through the precipitated material to a radial spiked conveyor. Yet another form is equipped with projecting tines, in one case projecting from the surface, and in another case radial spikes project from inside the cover through holes to the outside. ADVANTAGE - Free precipitation without danger of blockage or snarling.
