Description

The more uniform electronic unloading silo of cloth grain

Technical field

The invention belongs to barn structure design field, and in particular to a kind of more uniform electronic unloading grain of cloth grain Storehouse.

Background technology

Modernization grain logistics requirement conveying grain into storehouse export is fast, and government investment has been built up and large-scale has been with silo, vertical silo Main modernization grain depot, both storehouse types have the advantages that floor space is relatively small, storage capacity is big, mechanization degree is high, greatly The big speed of bin charging and discharging for accelerating grain；But because silo and vertical silo only have one grain inlet in top, grain inlet is away from ground Face is up to tens of rice, because impurity is different with the physical property of grain when entering grain, can cause the miscellaneous automatic classification of serious grain Phenomenon, causes the impurity cylindrical zone of mineral substance impurity range, particularly circle centre position, and light-duty impurity floats to surrounding and forms one in surrounding Individual annular light impurity area, particularly the impurity cylindrical zone of circle centre position, because a large amount of trifle in the worlds, broken grain make grain heap voidage very Small, influence Grain Ventilation cooling precipitation and fumigant insect killing, impurity carry the safe storage that a large amount of microorganisms have a strong impact on grain.This Individual region often generates heat during food storage, mildews, lumps, and has a strong impact on foodstuff preservation safety, increases the work of foodstuff preservation Measure.Enter grain from grain inlet and excessively concentrate to cause automatic classification to cause accumulation of impurities to reduce grain, also take at present Certain measure, for example, set a cone-shaped hood by grain inlet lower section, the grain for flowing into grain inlet is moved out along cone-shaped hood inclined-plane A dynamic segment distance, is fallen with the concentration for disperseing grain, but this method can only become a ring grain is entered by a point, in cone The lower section of shape cover mouthful still can form an impurity ring region, it is impossible to effectively eliminate accumulation of impurities, because effect is bad, at present seldom Using not being widely applied so far.In addition, silo traditional at present, mostly using monolithic design, can only simultaneously store one Plant grain, unitary function.Also there is part silo to use catamaran design, but but use two sets of single each self-unloadings of discharge mechanism Grain, causes to take up an area larger, relatively costly shortcoming.
