The operation principle of this base case is：Grain raw material is added to charge door, control elevator action, grain original
Material is promoted by feeding tube.When having dust to be fallen into transparent pipe by filter screen in grain raw material, light-emitting device is sent out
Light after the transparent pipe for being connected with dust, received light intensity is converted to electric signal, electric current by photoelectric conversion device
Table can deflect, and since the flow of dust in transparent pipe is bigger, light intensity is weaker, and the electric signal being converted into is weaker, also
It is that ammeter deflection angle changes greatly, the dust exceeding being indicated above in this batch of grain raw material is controlled by regulating valve and closed
Close bifurcated pipe, by the top of transparent pipe filter screen extract out, make grain raw material glide and by feed opening drop down onto in sieving net cylinder into
Row sieving dust removal process；When ammeter deflection angle tends towards stability, the dust being indicated above in this batch of grain raw material is not exceeded, leads to
It crosses control and regulation valve and closes feeding tube, grain raw material is made to be directly entered body feed tank along bifurcated pipe.
In the sieving net cylinder that grain raw material falls into lower section, motor drives shaft to do the rotating forward of certain angle, then inverts extensive
It is multiple, and then drive sieving net cylinder does the reciprocally swinging of certain angle, when the supporting rod in sieving net cylinder turns far from dedusting chamber interior wall
