Description

Spiral conveying machine

The utility model relates to a kind of stage casing outer rim supporting conveyor screw, it is that a kind of length in the handling machinery is apart from load transfer device, it can be widely used in industry-by-industry and departments such as metallurgy, mine, coal, electric power, chemical industry, grain, food and farming and animal husbandry, is the stronger universal equipment of comformability.

As everyone knows, conveyor screw is a kind of simple in structure, compact, good airproof performance, the defeated big continous way load transfer device of material amount.But amount of deflection influence because of its screw rod, the length of conveyor screw generally is no more than 3-4 rice, otherwise just needs on the screw mandrel of the stage casing of conveyer drop-hanger bearing to be set, and fuselage is long more, the quantity of drop-hanger bearing is many more, and the interruption times of helicallobe also increases thereupon.And the interruption of helicallobe has destroyed the continuity and the globality of defeated material driving surface, has influenced mass transport efficient; And because of drop-hanger bearing is difficult to fix, its stability and rigidity are all lower, and the vibration of equipment operation is bigger, and parts rapid wear, fault are more.

The purpose of this utility model is to design a kind of stage casing outer rim supporting conveyor screw, take the mode of spiral outer rim supporting to replace above-mentioned drop-hanger bearing, realize the continuous and complete of conveyer internal helical blades, guarantee the firm and stable of stage casing bearing brackett, improve long operation stability and transport efficiency apart from conveyor screw.

The purpose of this utility model is achieved in that

The utility model mainly comprises fixedly casing, feed inlet and outlet, two ends bearing, S. A., helicallobe, it is characterized in that: stage casing outer rim supporting device is: the outer rim at helicallobe evenly is provided with steel ball shape bearing, the steel ball of this bearing contacts with the fixing inner cylinder face of casing, steel ball is fixed by the inside and outside retainer of helix, inside and outside retainer is fixed on the non-working surface of helicallobe, and collet is fixed between retainer and the helicallobe.

Below in conjunction with drawings and Examples the utility model is further specified:

Fig. 1,2 is the analysing and observe in length and breadth of local stage casing outer rim supporting of first embodiment, and Fig. 3 is that the local A of Fig. 2 analyses and observe.Supporting helicallobe 2 outer rims promptly is the fixedly casing 1 of carrying material among the figure, and rotatable helicallobe 2 is through being distributed in the steel ball shape bearing on the outer rim, and its steel ball 3 contacts with the fixing interior garden cylinder of casing 1, is a kind of internal support form.The inside and outside retainer 8 of the helix of steel ball 3 and 9 is fixed on the non-working surface of helicallobe 2 fixing by bolt 5, nut 7, packing ring 6, collet 4 is between interior retainer 8 and helicallobe 2.

Fig. 4,5 is longitudinal and transverse analysing and observe of the local stage casing outer rim supporting of second embodiment, the stage casing outer rim supporting device here is to support by being contained in the support roller formula bearing that can revolve outside the casing 09, it is a kind of external support form, its structure is: can revolve casing 09 and captive joint with helicallobe 2, and can rotate synchronously; Can revolve casing 09 two ends and fixedly casing 1 forward insert by materials flow, be leading portion fixedly the material of casing 1 go out end and insert the material that next joint can revolve casing 09 and go into end, the material that can revolve casing 09 go out end insert again next joint fixedly the material of casing 1 go into end, its overlapping part has collet 04 to seal; Supporting can be revolved uniform its periphery of support roller formula bearing of casing 09, and the roller 03 of this support roller formula bearing is fixed on the bearing 08 by bearing pin 05, spring cotter 06,

packing ring

07, and 08 of bearing is fixed in ground or frame.

The part of the 3rd embodiment shown in Figure 6 is partly cutd open figure and has been showed another external support form, can revolve casing 09, helicallobe 2 among the figure, fixedly the assembly relation of casing 1 and collet 4 is identical with second embodiment.It removes support roller formula bearing, and be fixed with the roller bearing in the outer rim that can revolve casing 009, the roller 003 of this roller bearing evenly is fixed in the bearing box 008 by bearing seat 012, bolt 005 packing ring 007 is fixed as one bearing box 008 and bearing lid 010, and fix on the ground, locknut 006 is fixed on the inner sleeve of bearing seat 012 on the outer wall that can revolve casing 009, also is provided with seal ring 011 in bearing box 008 and the bearing lid 010.
