Description
Technical field
The utility model is related to a kind of Shaftless screw conveyor.
Background technology
At present, Shaftless screw conveyor mainly by drive device, head assembling, casing, shaftless screw body, cell body liner plate,
Charging aperture, discharging opening and cover are constituted, due to using the design of non-stop layer axle, being pushed away using the integrated steel spiral with certain flexibility
Material is sent, therefore the material that tradition has screw conveyor shaft and belt conveyor to be difficult conveying, such as graininess, powder can be conveyed
Shape, wet feed, pasty material, semifluid material and viscous material etc., but conveying powder or paste using non-shaft conveyor
During shape material, in order to improve transfer efficiency, sharf is often selected away from the smaller and less Shaftless screw conveyor of caliber, this
The material extruding force that kind structure for conveying is easily caused in conveyer is excessive, and damaged blade, is especially using longer shaftless spiral shell
It is even more that damage is serious during rotation body, not only delays the duration, and maintenance cost is high.
Utility model content
The utility model purpose is that the defect existed for prior art provides a kind of Shaftless screw conveyor.
The utility model to achieve the above object, is adopted the following technical scheme that：A kind of Shaftless screw conveyor, including casing
2nd, cover 1 and shaftless screw body 6, the cover 1 are arranged on casing 2, and a medial surface is provided with inside casing 2 for cambered surface
Lower liner plate 4, and the upper liner plate 3 that medial surface is cambered surface, the cambered surface of the upper liner plate 3 and lower liner plate 4 encloses in casing 2
Into a circular passage, the shaftless screw body 6 is located in the passage；Wherein, on the tiling at the lower two ends of liner plate 4
It is mounted with respectively around a spring supporting bolster 5, the spring supporting bolster 5 and is provided with an elastic packing air cushion
51；The spring supporting bolster 5 and elastic packing air cushion 51 constitute a resilient support sealing device.
Wherein, it is provided with sponge filler 7 between the cover 1 and the upper liner plate 3.
Wherein, the shaftless screw body 6 includes the inner side helical blade 61 that is made up of charcoal element alloy steel, and with it is described interior
The outer helical blade 62 being made up of charcoal element alloy steel that side helical blade 61 is connected, the section of the inner side helical blade 61 is wide
Degree is more than the cross-sectional width of the outer helical blade 62, and the section thickness of the inner side helical blade 61 is less than the outside spiral shell
The section thickness of vane piece 62.
The beneficial effects of the utility model：The utility model is during conveying, when solid accumulation extrudes blade, meeting
Liner plate is beated upwards in the presence of spring supporting bolster, expand the conveying space of material, mitigate to shaftless screw body
The damage of blade, after the material in be deposited in is discharged from Shaftless screw conveyor, in the reaction of spring supporting bolster
Under, liner plate can be made to return on initial position, in addition, elastic packing air cushion is provided with the periphery of spring supporting bolster,
Gap seals between upper liner plate and lower liner plate can be lived, prevent the material from leakage in conveyer from going out conveyer, because having
Elasticity, therefore air cushion can expand or shrink with the bounce of upper liner plate, and then can be by between upper liner plate and lower liner plate
Gap seals live.And spring supporting bolster and elastic packing air cushion are set together and constitute an elastic sealing device,
The reliability of equipment can be more improved, maintenance cost is reduced.
Brief description of the drawings

Fig. 2 shaftless screw body structural representations of the present utility model.
Embodiment
Shown in Fig. 1, it is related to a kind of Shaftless screw conveyor, including casing 2, cover 1 and shaftless screw body 6, the cover 1
On casing 2, the lower liner plate 4 that a medial surface is cambered surface is installed inside casing 2, and a medial surface is cambered surface
Upper liner plate 3, the cambered surface of the upper liner plate 3 and lower liner plate 4 surrounds a circular passage, the shaftless screw in casing 2
Body 6 is located in the passage；Wherein, a spring supporting bolster 5 is mounted with respectively on the tiling at the lower two ends of liner plate 4,
An elastic packing air cushion 51 is provided with around the spring supporting bolster 5.The spring supporting bolster 5 and elastic packing
Air cushion 51 constitutes a resilient support sealing device.
The utility model, when solid accumulation extrudes blade, can make liner plate slow in spring supporting during conveying
Beated upwards in the presence of stamping, expand the conveying space of material, mitigate the damage to shaftless screw body blade, in being deposited in
Material discharged from Shaftless screw conveyor after, under the reaction of spring supporting bolster, can make liner plate return to just
On beginning position, in addition, be provided with elastic packing air cushion in the periphery of spring supporting bolster, can by upper liner plate and lower liner plate it
Between gap seals live, prevent the material from leakage in conveyer from going out conveyer, because flexible, therefore air cushion can be with upper
The bounce of liner plate and expand or shrink, and then the gap seals between upper liner plate and lower liner plate can be lived.And by spring branch
Support bolster and elastic packing air cushion, which are set together, constitutes an elastic sealing device, can more improve the reliability of equipment,
Reduce maintenance cost.
In addition, being provided with sponge filler 7 between the cover 1 and the upper liner plate 3, liner plate 3 can be allowed to jump upwards
Effect with a buffering when dynamic, prevents liner plate 3 from causing mechanical failure to the cover on top.
Shown in Fig. 2, the shaftless screw body 6 includes the inner side helical blade 61 that is made up of charcoal element alloy steel, and with institute
State the outer helical blade 62 being made up of charcoal element alloy steel that inner side helical blade 61 is connected, section of the inner side helical blade 61
Face width is more than the cross-sectional width of the outer helical blade 62, and the section thickness of the inner side helical blade 61 is less than outside described
The section thickness of side helical blade 62.Using the shaftless screw body 6 of the structure, the rigidity of conveyor screw can be greatly improved and used
In the life-span, its abrasion is reduced, the conveying capacity of equipment is improved.
Preferred embodiment of the present utility model is the foregoing is only, it is all in this practicality not to limit the utility model
Within new spirit and principle, any modification, equivalent substitution and improvements made etc. should be included in guarantor of the present utility model
Within the scope of shield.
