Abstract
The utility model provides a shaftless screw conveyor, mainly by the casing, cover and shaftless spiral body constitute, the cover is installed on the casing, install the lower liner board of a bottom surface for the cambered surface at chassis bottom, shaftless spiral body settles on the lower liner board, it is still including installing the last welt in the casing, the one side that goes up the welt is the cambered surface, go up the cambered surface of the cambered surface of welt towards the lower liner board, enclose into a circular shape passageway by the cambered surface of last welt and lower liner board in the casing, shaftless spiral body is located this passageway, install many springs between last welt and cover, it has an air cushion to settle respectively on the tiling at lower liner board both ends, the tiling of going up the welt both ends supports and leans on on the air cushion, one end at the air cushion is equipped with a fastening portion, the fixed connection of fastening portion is on the casing, the utility model discloses can reduce because of the too big damage to the shaftless spiral body blade of extrusion force in the process of carrying powder or paste -like material.
Description
Technical field
This utility model relates to a kind of Shaftless screw conveyor.
Background technology
nullShaftless screw conveyor is mainly by driving device、Head assembles、Casing、Shaftless screw body、Cell body liner plate、Charging aperture、Discharging opening and cover are constituted，Owing to adopting the design of non-stop layer axle，Utilize the integrated steel spiral pushing material with certain flexibility，Therefore tradition can be carried to have the material that screw conveyor shaft and belt conveyor are not easily carried，Such as graininess、Powdered、Wet feed、Pasty material、Semifluid material and viscous material etc.，But when using non-shaft conveyor conveying powder or pasty material，In order to improve transfer efficiency，Often select sharf from less and that caliber is less Shaftless screw conveyor，The material extruding force that this structure for conveying easily causes in conveyer is excessive，And damaged blade，Damage serious during particularly in use longer shaftless screw body especially，Not only delay the duration，And maintenance cost is high.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of Shaftless screw conveyor, it is possible to the process at conveying powder or pasty material reduces because of the excessive damage to shaftless screw body blade of extruding force.
In order to solve the problems referred to above, the technical solution adopted in the utility model is: a kind of Shaftless screw conveyor, main by casing, cover and shaftless screw body composition, cover is arranged in casing, at bottom of shell, the lower liner plate that one bottom surface is cambered surface is installed, shaftless screw body is placed on lower liner plate, it also includes the upper liner plate being arranged in casing, the one side of upper liner plate is cambered surface, the cambered surface of upper liner plate is towards the cambered surface of lower liner plate, in casing, a circular passage is surrounded by the cambered surface of upper liner plate and lower liner plate, shaftless screw body is positioned at this passage, many springs are installed between upper liner plate and cover, the tiling at lower liner plate two ends is mounted with an air cushion respectively, the tiling at upper liner plate two ends is resisted against on air cushion, a fastening part it is provided with in one end of air cushion, fastening part is fixedly connected in casing.
Further, the tiling at upper liner plate and lower liner plate two ends is inclined-plane.
Technique effect after use this utility model is: in the process of conveying, when solid accumulation extrudes blade, liner plate can be made upwards to beat, expand the conveying space of material, alleviate the damage to shaftless screw body blade, when being deposited in after interior material discharges from Shaftless screw conveyor, effect at spring, liner plate can be made to return on initial position, the effect of air cushion is in that, 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 along with upper beating of liner plate or shrink, and then the gap seals between upper liner plate and lower liner plate can be lived.
Accompanying drawing explanation
Fig. 1 is generalized section of the present utility model,
Fig. 2 is that master of the present utility model looks partial cutaway schematic.
Detailed description of the invention
nullAs illustrated in fig. 1 and 2: a kind of Shaftless screw conveyor，Main by casing 1、Cover 2 and shaftless screw body 3 form，Cover 2 is arranged in casing 1，The lower liner plate 4 that one bottom surface is cambered surface is installed bottom casing 1，Shaftless screw body 3 is placed on lower liner plate 4，It also includes the upper liner plate 5 being arranged in casing 1，The one side of upper liner plate 5 is cambered surface，The cambered surface of upper liner plate 5 is towards the cambered surface of lower liner plate 4，In casing 1, a circular passage is surrounded by the cambered surface of upper liner plate 5 and lower liner plate 4，Shaftless screw body 3 is positioned at this passage，Between upper liner plate 5 and cover 2, many springs 7 are installed，The tiling at lower liner plate 4 two ends is mounted with an air cushion 6 respectively，The tiling at upper liner plate 5 two ends is resisted against on air cushion 6，A fastening part 61 it is provided with in one end of air cushion 6，Fastening part 61 is fixedly connected in casing 1，Air cushion 6 can be the rubber blanket that inside is filled with gas.
Further, the tiling at upper liner plate 5 and lower liner plate 4 two ends is inclined-plane, and this structure can increase the contact area of upper liner plate 5 and lower liner plate 4 and air cushion 6 so that air cushion 6 sealing effectiveness is better, and tiling is the plane of liner plate cambered surface both sides.
In the process of conveying, when solid accumulation extrudes blade, liner plate 5 can be made upwards to beat, expand the conveying space of material, alleviate the damage to shaftless screw body 3 blade, when being deposited in after interior material discharges from Shaftless screw conveyor, effect at spring 7, liner plate 5 can be made to return on initial position, the effect of air cushion 6 is in that, gap seals between upper liner plate 5 and lower liner plate 4 can be lived, prevent the material from leakage in conveyer from going out conveyer, because having elasticity, therefore air cushion 6 can expand along with upper beating of liner plate 5 or shrink, and then the gap seals between upper liner plate 5 and lower liner plate 4 can be lived.
