Roughing is weldingly fixed on spiral central siphon after stretching, and lathe finishing spiral outer diameter is recycled to obtain the helical axis of finished product.But
The outer diameter for being helical blade in actual use can be because become smaller and smaller with material abrasion, until cannot reach expected
Conveying capacity or discharging quantity.It will result in maintenance shut-downs in this way, the outer diameter built-up welding production again to helical blade, outer diameter heap postwelding
Helical axis both ends need to fix floating rule with bracket according to the outer diameter of spiral and manually carry out reconditioning, time-consuming and laborious, system-down maintenance
Period is longer and influences production efficiency.
Utility model content
For above-mentioned in the prior art since helical blade has grindability in actual use, frequent maintenance spiral is needed
The problem of conveyor blade, the utility model provide a kind of improved screw conveyor, extend spiral service life to reach, contracting
The purpose in short system maintenance period.
A kind of improved screw conveyor of the utility model, including helical axis and helical blade, helical blade include solid
Fixed blade and several abrasion-resistant stee moving vanes, fixed blade are twist fixedly welded on helical axis, fixed blade include with
The working face that material is in contact, moving vane is coaxial with fixed blade and is removably attached to fixed blade evenly and at intervals
On, and the outer diameter of moving vane is greater than the outer diameter of fixed blade.
Preferably, all moving vanes all are the same size.
Preferably, the moving vane is fixedly mounted on the back side of fixed blade working face.
Preferably, fixation is bolted in the moving vane and fixed blade.
Preferably, the distance of central axis of threaded hole in the fixed blade to the helical axis is equal.
Preferably, the surface radian construction of the moving vane is identical as fixed blade.
Preferably, several moving vanes be cast molding after simultaneously be process on grinding machine.
Compared with prior art, a kind of improved screw conveyor of the utility model, by removable in fixed blade
Installation activity blade is unloaded, and the outer diameter of moving vane is greater than the outer diameter of fixed blade, in material conveying, moving vane is prior to solid
Fixed blade generates gauge wear, avoids the gauge wear of fixed blade, ensure that the conveying capacity and discharging quantity of material, extend
The service life of screw conveyor；It can quickly be replaced after moving vane is worn, substantially reduce system maintenance
Period improves production efficiency.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of traditional screw conveyor.
Fig. 2 is a kind of structural schematic diagram of improved screw conveyor of an embodiment of the present invention.
Fig. 3 is a kind of schematic side view of improved screw conveyor of an embodiment of the present invention.
Specific embodiment
To make to have further understanding to the purpose of this utility model, construction, feature and its function, hereby cooperate embodiment
Detailed description are as follows.
Refer to Fig. 2 and Fig. 3, a kind of improved screw conveyor of the utility model, including helical axis 1 and helical blade
2, helical blade 2 includes fixed blade 21 and several moving vanes 22, and fixed blade 21 and moving vane 22 are fan annular, Gu
Fixed blade 21 is twist fixedly welded on helical axis 1, and fixed blade 21 includes the working face 212 being in contact with material, living
Movable vane piece 22 is coaxial with fixed blade 21 and is removably attached to the back side of the working face 212 of fixed blade 21, moving vane
22 outer diameter D is greater than the outside diameter d of fixed blade 21, and the outer diameter of all moving vanes 22 is all equal.
In a preferred embodiment, it is provided with threaded hole in fixed blade 21, is provided on moving vane 22 corresponding
Bolt hole 4, fixed blade 21 and moving vane 22 are detachably fixed connection by bolt.Further, in fixed blade 21
The distance of central axis of threaded hole to helical axis 1 is equal.
Referring to Fig. 3, by the bolt hole 4 on moving vane 22 it is corresponding with the screw thread hole site in fixed blade 21 after, make
Moving vane 22 is fixed on the working face 212 of fixed blade 21 with bolt, at this point, moving vane 22 and fixed blade 21 are total
The outer diameter D of axis and moving vane 22 is 2 ㎜ bigger than the outside diameter d of fixed blade 21 or so.Circumferentially successively connect in fixed blade 21
Continuous fixed multiple moving vanes 22.When screw conveyor works, moving vane 22 is in contact with material to be generated prior to fixed blade
Gauge wear is to protect fixed blade 21 to slow down or it is avoided to generate gauge wear, when moving vane 22 does not have because of abrasion
When protecting the effect of fixed blade 21, the moving vane that need to only dismantle abrasion installs new moving vane.
The moving vane 22 of the present embodiment is cast into base using the such as high manganese wear-resistant steel of High wear-resistant steel, is then attached to blade
Grinding is carried out on grinding machine special plane, in a preferred embodiment, a collection of moving vane can be fixed on grinding machine simultaneously

Dimensions is consistent as much as possible, is gone on smoothly conducive to the conveying unloading work of screw conveyor.
A kind of improved screw conveyor of the utility model, by installation activity blade detachable in fixed blade,
And the outer diameter of moving vane is greater than the outer diameter of fixed blade, in material conveying, moving vane generates radial prior to fixed blade
Abrasion, avoids the gauge wear of fixed blade, ensure that the conveying capacity and discharging quantity of material, extend making for screw conveyor
Use the service life；It can quickly be replaced after moving vane is worn, substantially reduce the period of system maintenance, improve production
Efficiency.
The utility model is described by above-mentioned related embodiment, however above-described embodiment is only to implement the utility model
Example.It must be noted that the embodiment disclosed is not limiting as the scope of the utility model.On the contrary, not departing from this
