Gearratio be 2:1；The gearratio of the active gear wheel engaged transmission of the small transition gear and (n+1)th disk roller is 2:1；Cause
Gearratio between this two neighboring disk roller is 4:1.
Above-mentioned converter steel scrap adds in hopper, and the number of gear teeth set on the first disk roller outer wall is preferably 5.
Above-mentioned converter steel scrap adds in hopper, and the wall box and bottom plate use welded-steel plate construction；The reinforcing rib
Using channel steel structure, it is fixed on by welding manner on wall box.
The present invention adds in hopper for a kind of converter steel scrap, during steel scrap is added in into steelmaking converter, passes through overhead traveling crane
Hopper babinet equipped with steel scrap material is hoisted to converter charge door position, is tilted a certain angle hopper babinet, hopper babinet
In steel scrap material be introduced under self gravitation effect by discharge port in converter charge door, the steel scrap material at the same time toppled over
The gear teeth of the first disk roller outer wall are hit, the first disk roller is made to be rotated around the first rolling axle, driving force band moving gear is on the one hand generated and passes
Motivation structure operates, then the row's disk roller retarded motion step by step from front to back for making to be arranged at the bottom of box by gear transfer mechanism,
The packing phenomenon at fire door position is avoided caused by rapidly the toppling over of steel scrap material with this, is on the other hand set on the first disk roller outer wall
The gear teeth put may also function as material toggling effect, so that steel scrap material can be added in smoothly in converter；In addition disk roller of the invention is set
Two kinds of models of major diameter disk roller and minor diameter disk roller, major diameter disk roller and minor diameter disk roller arranged for interval are put, thus at babinet bottom
Face forms the structure that is uneven, and when steel scrap hopper topples over material into converter, rugged babinet has the bottom of drop
Material is made to generate shock of jolting, so as to further avoid the packing phenomenon of material.It can be seen that the present invention solves steel scrap object
Expect in adition process fire door accumulate the problem of, realize and improve that steel scrap adds in smoothness, increasing converter enters stove steel scrap ratio
Advantageous effect.

Peripherally disposed 5 gear teeth 5-1-1 on one disk roller 5-1 outer walls.
Referring to Fig. 4, Fig. 5, converter steel scrap of the present invention adds in hopper, and the disk roller 5 includes major diameter disk roller and small straight
Thus two kinds of models of footpath disk roller, major diameter disk roller and minor diameter disk roller arranged for interval form the knot that is uneven in 1 bottom surface of babinet
Structure, when steel scrap hopper topples over material into converter, rugged 1 bottom surface of babinet makes material generate shock of jolting, and generation falls
The effect of poor effect, so as to avoid the packing phenomenon of material；The present invention also sets gear drive between two neighboring disk roller
Mechanism 4, the gear drive 4 use deceleration transmission pattern, gearratio 4:1；Master is set in gear drive 4
Dynamic gear wheel 4-1, driven pinion 4-2, great transition gear 4-3 and small transition gear 4-4, wherein, the master of n-th of disk roller 5-n
Dynamic gear wheel 4-1 and driven pinion 4-2 is coaxially assembled, and the driven pinion 4-2 is with being located at n-th of disk roller 5-n and (n+1)th
Great transition gear 4-3 engaged transmissions between a disk roller 5-n+1, gearratio 2:1, the great transition gear 4-3 and small mistake
It crosses gear 4-4 coaxially to assemble, the active gear wheel 4-1 engaged transmissions of the small transition gear 4-4 and (n+1)th disk roller 5-n+1,
Its gearratio is 2:1.
Referring to Fig. 1 to Fig. 8, the process that hopper adds in steel scrap into steelmaking converter is added in using converter steel scrap of the present invention
In, the babinet 1 equipped with steel scrap material 7 is hoisted to by converter charge door position by overhead traveling crane, is tilted a certain angle babinet 1, case
Steel scrap material 7 is entered by discharge port 1-1 in converter charge door under self gravitation effect in body 1, the steel scrap at the same time toppled over
Material 7 hits the gear teeth 5-1-1 of the first disk roller 5-1 outer walls, and the first disk roller 5-1 is made to be rotated around the first rolling axle, on the one hand generates
Driving force drives gear drive 4 to operate, then makes the retarded motion step by step from front to back of disk roller 5 by gear transfer mechanism 4, keeps away
Exempt from caused by rapidly the toppling over of steel scrap material 7 packing phenomenon at fire door position, on the other hand gear teeth 5-1- on the first disk roller 5-1
1 may also function as material toggling effect, so that steel scrap material 7 is successfully added in converter.
