The present embodiment major-minor is transported by charging ribbon conveyer 9 across circular stockyard raw material, through stacker 10 heapsTo stockpile 17 and secondary stockpile 171, stacker 10 carries out windrow around newel 12 rotations; The 3rd ring-type is walkedShape track 16 is arranged on the upper brace of pillar 19, and the upper end of reclaimer 11 is the 3rd of pillar 19 theWalking on ring-type track 16 out of shape, and rotate around newel 12, during the raw material that reclaimer 11 takes out entersHeart funnel 13, is expected that through feeding device 14 discharging ribbon conveyer 15 is transported to user; Shoving rake 3Control by hoisting mechanism 4 and Electrohydraulic push rod 5, the raw material of secondary stockpile 171 is shifted onto to the position of stockpile 17Put, be convenient to reclaimer 11 and take out.
The present embodiment major-minor is cancelled after barricade 20 across circular stockyard, in the periphery of barricade, the first ring-type is set out of shapeTrack and the second ring-type track out of shape, pusher is up at the first ring-type track out of shape and the second ring-type track out of shapeWalk, the top of pusher arranges arc pair across canopy 8, and is connected with arc main span canopy 18, because barricade 20 is thrownProvide very large, deduction pusher equipment and the first ring-type track out of shape thereof and the second ring-type track out of shape, arc pairAcross investments such as canopies, compared to the prior art, can reduce approximately 20%～30% construction investment, barricade is higher to fallWidth is also larger; Owing to having cancelled barricade, the raw material of stockpile flows to the outside of pillar naturally again, and forms secondary materialHeap, compared to the prior art, can increase by approximately 15%～40% storing material amount; From Fig. 3 and the secondary material of Fig. 6That piles is more known, and original barricade is higher, the diameter E of material shed is less, cancels after barricade, at the high F of heapIn identical situation, the storage capacity percentage of increase is also larger.
Relatively can find out from Fig. 3 and Fig. 6, in the situation that the high F of heap is identical, in order to reduce arc main spanThe investment of canopy and reclaimer, can flexibly select optimized arc main span canopy according to site condition when designThe span of diameter E and reclaimer; Again because pusher does not participate in interlocked control, only as producing auxiliary establishingStandby, therefore, according to need of production, can on the first ring-type track out of shape and the second ring-type track out of shape, configure2 or many pushers; Connect again because arc pair is sealed secondary stockpile completely across canopy, and with arc main span canopyConnect, therefore, can reduce the pollution to surrounding enviroment, reduced again the material that rainwater and wind-force causeLoss, also can improve production operation condition and surrounding enviroment.
The present embodiment major-minor is across circular stockyard, in the case of the height F of stockpile is constant, can increase circleThe storage amount in stock ground, reduces civil engineering and equipment investment, reduces design difficulty, improves the reliability of equipmentAnd the security of material shed structure, protection surrounding enviroment, improve production operation condition.
Compared with prior art its advantageous effect systematic generalization is as follows across circular stockyard for the present embodiment major-minor:
1, because technique scheme has been cancelled circular barricade 20, in the situation that stock ground storage capacity is constant, buttonExcept newly increasing pusher equipment and track out of shape thereof, arc pair across investments such as canopies, can reduce approximately 20%～30%Construction investment, the higher range of decrease of barricade is also larger;
2, because technique scheme has been cancelled circular barricade, can increase by approximately 15%～40% storing materialAmount; Circular stockyard barricade is higher, diameter is less, and in the situation that heap height is identical, the storage capacity of increase is also got overGreatly;
3, in the situation that storage capacity is constant, in order to reduce civil engineering and equipment investment, can be according to field when designGround condition is selected the diameter of optimized reclaimer and the span of pusher flexibly;
4, pusher does not participate in interlocked control, in stock ground as production auxiliary equipment, according to need of production,Can on same track, configure many;
5, arc main span canopy 18 seals stockpile across canopy 8 completely with arc pair, can reduce Zhou BianhuanThe pollution in border, has reduced again the loss of material that rainwater and wind-force cause, and also can improve production operation conditionAnd surrounding enviroment.
Above, be only preferred embodiment of the present invention, but protection scope of the present invention is not limited to this, appointWhat is familiar with those skilled in the art in the technical scope of the present invention's exposure, the variation that can expect easilyOr replace, within all should being encompassed in protection scope of the present invention. Therefore, protection scope of the present invention should be withThe protection domain that claim defines is as the criterion.
