General Information
Grain, chaff, and unthreshed heads which penetrated the
separator grates are carried to the cleaning shoe by the
separator return pan (7).
Cleaning
The material is moved from the front of the separator
return pan onto a short cascade pan (8) which in turn
moves the mixture across a fingered comb and into the
front of the chaffer sieve.
The cleaning fan (9) provides air to keep the chaff in
suspension during the cleaning process in the shoe.
The air blast passing through the reciprocating adjustable
chaffer (10) separates and blows the chaff out of the
combine. The grain and tailings drop through to the
cleaning sieve.
The adjustable cleaning sieve (11) does the final
cleaning. The clean grain falls through the sieve into the
clean grain auger trough. The tailings, chaff and other
material continue to the end of the sieve and into the
return auger trough (12) for reprocessing.
The grain elevator paddle chain conveys the clean grain
from the clean grain auger (13) to the grain tank filling
auger and into the grain tank (14). The return elevator
carries the tailings back to the rotor intake for threshing
and processing.
The grain in the grain tank is unloaded into a truck or
trailer through the unloading auger (15).
