De- screw feeder is stated again to be connected by screw feeder cylinder with the threshing cylinder.After crops threshing drum feed is carried out threshing, than
Biggish some stalks are carried over by threshing cylinder, then some grain and part of it stalk will be fallen on concave grate
By the first screening of concave grate, grain and a part of lesser stalk will be fallen on sorting screen, by the sieve of sorting screen
After choosing because self gravity fall to the grain in main de- storehouse will absolutely not sundries, de- storehouse is funnel-shaped structure because based on
And main de- screw feeder be set to main de- storehouse bottom thus grain can by be packed after main de- screw feeder, sorting screen into
Air blower can be blowed against sorting screen always during row screening, and stalk lesser in this way will be because of wind-force toward threshing
Roller output extreme direction is walked, but also with a part of grain especially when crop yield is bigger in these stalks
Often will be more, the entrance for taking off storehouse again is towards the output end side of the threshing cylinder, so when by sorting screen
Part stalk after screening will be fallen to multiple to storehouse entrance is taken off again with part stalk kernelly because of gravity in this way
