Feeding, threshing, separation and impurities removal.When work, 804 drive roller shaft 801 of drum shaft driving motor drives threshing cylinder 8 to rotate,
Corn ear enters in the threshing chamber being made of top cover 2, threshing concave plate 6 and separation notch board 4 from feeding 1 side of protective cover, completes
Feeding process；Fruit ear is completed de- in the case where being detached from the effects of interior is by the impact of threshing cylinder 8 and threshing concave plate 6, collision, rubbing
Grain process；In this region, for threshing concave plate 6 under the adjusting of threshing concave plate self-excitation regulating mechanism 7, threshing concave plate 6 can be with hangers 601
It pumps for rotation center, adapts to different feed quantities automatically, realize concave clearance (threshing concave plate and threshing roll
The distance of threshing element most significant end on cylinder) automatic adjustment, effectively reduce the rigid shock of fruit ear, reduce the machine of corn kernel
Tool damage, completes threshing course.Wherein, it in threshing concave plate self-excitation regulating mechanism 7, can be replaced according to the height of Moisture of Maize
(moisture content is high, fruit ear easy damaged, and the spring for selecting stiffness factor small takes off at this time for the coil expander 704 of different stiffness factors
Grain notch board 6 is small to fruit ear active force, reduces fruit ear mechanical damage；Conversely, the spring that selection stiffness factor is big, increases threshing concave plate
6 pairs of fruit ear active forces guarantee threshing performance).When not purifying at fruit ear arrival separation notch board 4, notch board is separated each four in front and back
Separate notch board self-excitation regulating mechanism 5 adjusting under, have certain flailing action to fruit ear is not purified, then realize corn kernel with
Miscellaneous remaining separation, completes separation process.5 pairs of notch board self-excitation regulating mechanism separation notch boards 4 of separation have certain concave clearance to adjust
Effect, the preferred 5 helical spring stiffness factor of self-excitation regulating mechanism for separating notch board 4 is than 6 self-excitation regulating mechanism of threshing concave plate, 7 spiral shell
Revolve device of spring stiffness coefficient it is big, main function be exactly prevent separation notch board 4 up and down motion amplitude it is excessive, avoid separation notch board 4 on
It is lower reciprocating motion excessively frequently result in is not purified in threshing chamber fruit ear vibration acutely, cannot make seed with it is miscellaneous it is remaining separate in time, lead
It causes the separation time elongated, causes seed mechanical damage larger.Finally, it is miscellaneous it is remaining through 3 discharger of impurities removal deflector outside, complete impurities removal
Process.
