Abstract

The utility model relates to a synchronizing belt lifting device for a bucket elevator. A head wheel and a tail wheel are designed into toothed wheels and the external side of the toothed wheel is provided with a guard ring; the inside of a bucket belt is provided with a tooth space. A middle layer is a chain whose upper side is provided with a rubber layer; an outermost layer is a bonding layer of rubber and wrapping cloth; one side of the bucket belt is provided with gear teeth and the other side is provided with a bucket; the bucket belt is arranged at the rear of the head wheel and the tail wheel. The utility model can effectively reduce slippage, can reduce strucken sparks and can enhance lifting efficiency, being a replacement device for lifting bulk materials.

Description

Bucket elevator is with bont synchronously

The utility model relates to mechanical field, and the synchronous band that particularly is applied to bucket elevator promotes structure.

At present, generally use the flat rubber belting bont in the bucket elevator of bulk cargos such as lifting grain, it is simple in structure, easy to use, but also there is following defective in this bont:

The one, the intensity of winnowing pan band is low.Flat rubber belting relies on canvas to bear the lifting pulling force, thereby insufficient strength; Particularly in the joint that winnowing pan place and winnowing pan band are installed, because of bolt hole is arranged, its intensity is more inadequate.

The 2nd, great wheel drives the motion of winnowing pan band by friction, in order between great wheel and winnowing pan band, to produce the friction of enough driving winnowing pan bands, must be with the tensioning of winnowing pan band, and this makes the axle of winnowing pan band and supporting head, tail wheel and bearing etc. bear bigger tensile force; Secondly, when tensile force in the winnowing pan band changed, the influence of the ability of correct wheel drive winnowing pan band was bigger, easily produces skidding.

Task of the present utility model is: design a kind of synchronous band bont, to overcome the defective that present flat rubber belting bont exists.

The purpose of this utility model is achieved in that

Head, tail wheel are gear, and the gear teeth are uniform on circumference, and the both sides outer rim of the gear teeth has back-up ring, and there is the tooth equidistant with the gear teeth winnowing pan band inboard, and winnowing pan is equipped with in the outside, and the winnowing pan band is enclosed within on great wheel and the tail wheel and locks with spring cotter.The winnowing pan band is composited by three layers, the interlayer that chain is in, and the chain outside is by the rubber parcel, and outermost layer is infantees and rubber adhesion layer.Chain by general carrier bar be connected the winnowing pan carrier bar and form, pass the chain plate hole by pivot pin and be linked to be integral body with the spring cotter locking, have for the nut hole that connects winnowing pan connecting on the carrier bar.

During bucket elevator work, power system drives the great wheel motion, and great wheel and winnowing pan band engagement drive winnowing pan band and winnowing pan move around tail wheel, by winnowing pan material are promoted.

The band elevator system has following advantage synchronously:

1, the winnowing pan band relies on chain to bear and promotes the tension intensity height.

2, be engaged transmission between head, tail wheel and the winnowing pan band, its driving efficiency height.Guaranteeing under the tensioning of winnowing pan band, can avoid winnowing pan band relative sliding movement on head, tail wheel.

3, do not need very big tensile force in the winnowing pan band, this reduces the wear-out of a bearing of supporting head, tail-gear spindle.

4, back-up ring prevents winnowing pan band sideslip effectively.

5, chain is surrounded by rubber, and bolt cap is embedded in the synchronous band, and when band work synchronously, chain, bolt cap can not clash into other metal and produce spark, cause the dust explosion accident.

Fig. 1 is the utility model integral structure scheme drawing

Fig. 2 is the carrier bar connection diagram

Fig. 3 is synchronous band structure scheme drawing

Among the figure: 1 great wheel, 2 winnowing pan bands, 3 winnowing pans, 4 tail wheels, 5 gear teeth, 6 back-up rings, 7 chains, 8 general carrier bars, 9 connect winnowing pan carrier bar, 10 pivot pins, 11 spring cotters, 12 rubber, 13 infantees layers, 14 winnowing pan band teeth, 15 bolts hole

Further describe technology contents of the present utility model and implementation method below in conjunction with accompanying drawing:

Great wheel 1 is gear with tail wheel 4, and its gear teeth 5 are uniform on circumference, and the both sides outer rim of the gear teeth 5 has the back-up ring 6 that is fixed together with wheel.

Chain 7 is positioned at the interlayer of winnowing pan band 2, and is surrounded by rubber 12, and the outermost layer of winnowing pan band is the gummed of infantees layer 13 and rubber 12, in its side equally spaced winnowing pan band tooth 14 is arranged.

Tooth 14 on the winnowing pan band 2 forms engagement in the teeth groove of great wheel 1, tail wheel 2, the both sides of winnowing pan band 2 are spacing by back-up ring 6 on great wheel 1, the tail wheel 4.

Chain 7 is by general carrier bar 8, the 9 adjacent connections of connection winnowing pan carrier bar, pass with pivot pin 10 and to insert spring cotter 11 behind the chain plate hole and form whole, connecting has two bolts hole 15 that connect winnowing pan 3 usefulness to be symmetrically distributed on the winnowing pan carrier bar 9, the connection winnowing pan carrier bar bolt hole 15 that bolt passes on the winnowing pan band 2 is fixing with winnowing pan 3, and bolt hole 15 is arranged in winnowing pan band tooth 14.

In bucket elevator when work,, head, tail wheel drive the winnowing pan band and rotate, and winnowing pan rises to top with bulk cargo from the bottom, owing to be the tooth transmission, not only transmission of power is good, and wear and tear little, efficient is high.
