Description

Self-rotary grain distributer

Technical field

The invention belongs to cloth grain equipment technical field, and in particular to a kind of self-rotary grain distributer.

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 adopt at present Certain measure is taken, for example, grain inlet lower section is set into a cone-shaped hood, make the grain for flowing into grain inlet outside along cone-shaped hood inclined-plane A mobile segment distance, is fallen with the concentration for disperseing grain, but this method can only become a ring grain is entered by a point, The lower section of cone-shaped hood mouthful still can form an impurity ring region, it is impossible to effectively eliminate accumulation of impurities, because effect is bad, at present very Few application, is not widely applied so far.

The content of the invention

The present invention provides one kind being capable of spinning and the more uniform self-rotary grain distributer of cloth grain.

Realizing the technical scheme of the object of the invention is：A kind of self-rotary grain distributer, including bearing block, it is rotatably arranged on bearing Rotating shaft on seat and the cloth grain part being fixedly installed in rotating shaft；The rotating shaft is set along plumb line direction；It is characterized in that：Cloth grain Part slips grain cylinder including a Ge Jiliang areas and eight；Ji Liangqu includes annular slab, circular bottom wall and eight involute plates, and rotating shaft is located at The center of circular bottom wall；The outer wall of the inner and rotating shaft of each involute plate is fixedly linked, the outer end of each involute and annular slab Inwall be fixedly linked, adjacent two involute plate clampings form a flow-guiding channel；Annular slab is provided with eight grain outlets, Each grain outlet is just set to a flow-guiding channel；Respectively slip grain cylinder to be fixedly installed on the periphery wall of annular slab, respectively slip grain cylinder and pass through One grain outlet and corresponding one lead grain channel connection, respectively slip grain cylinder and are obliquely installed along direction from top to bottom；Slip grain cylinder point Be two groups, each group slip grain cylinder along rotating shaft circumferential direction be successively it is huge slip grain cylinder, length slip grain cylinder, in slip grain cylinder and it is short slip grain cylinder, It is huge slip grain cylinder, length slip grain cylinder, in slip grain cylinder and it is short slip grain cylinder length shorten successively；Two groups are slipped grain cylinder and rotate shaft centre line in The heart is symmetrical arranged.

During present invention work, the underface of the grain inlet of silo is arranged on, collection is fallen into from grain inlet into the grain of silo In grain area, circular hole then from spindle central, grain outlet and respectively slip grain passage and fall, so as to produce tangential force to grain distributer, So that grain distributer rotates around the shaft, namely realizes spinning, grain is uniformly shed downwards, grain is entered so as to avoid free binning When free flowability difference impurity (powder, grass-seed, particle etc.) largely assemble in center industrialized regions, obtain the more uniform skill of cloth grain Art effect.
