Highly, H1For the height of feed bin trapezoidal portions, α is the angle with bin bottom for the side wall of feed bin trapezoidal portions.
10. device according to claim 7 it is characterised in that described motion control unit specifically for：
When receiving the signal that distributing device triggers SQM, judge that distributing device is positive or counter motion；
If positive movement, then first control distributing device positive movement tzTime, enter back into following circulation：Distributing device is controlled reversely to transport
Dynamic 2tfTime, then control distributing device positive movement 2tzTime；
If counter motion, then first control distributing device counter motion tfTime, enter back into following circulation：Control the positive fortune of distributing device
Dynamic 2tzTime, then control distributing device counter motion 2tfTime；
Wherein, tz=((1/2) L3)/Vz, tf=((1/2) L3)/Vf, L3For the width of material position, VzPositive movement speed for distributing device
Degree, VfThe position switch of the critical distance midpoint moved for distributing device for the counter motion speed of distributing device, SQM.
