Embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings, so that those skilled in the art
The utility model may be better understood and can be practiced, but illustrated embodiment is not as to restriction of the present utility model.
A kind of Shaftless screw conveyor, as shown in figure 1, including：Drive device 1, housing 2 and shaftless screw body 3, driving
Device 1 drives shaftless screw body 3 to be entered in the internal rotation of housing 2, material by feeding mouth 21, in pushing away for the blade of shaftless screw body 3
Under dynamic, discharged from discharging opening 22.
Wherein, as shown in Fig. 1 ~ 3, shaftless screw body 3 includes the first blade 31, the second blade 32, third blade the 33, the 4th
Blade 34, the 5th blade 35, the 6th blade 36.Wherein, the first blade 31 is located at feeding mouth 21, and the 6th blade 36 is positioned at discharging
At mouth 22.In Fig. 3, size A, B, C, D, E, F are respectively the diameter of the blade 36 of the first blade 31 to the 6th, and a, b, c, d, e distinguish
The spacing between blade two-by-two.By pan feeding to the direction that discharges, spiral spacing gradually increases, and blade diameter gradually increases.That is, A<B<C<
D<E<F, a<b<c<d<e.Wherein, A and a is standard size, i.e., spiral spacing and blade as defined on JBT 12636-2016
Diameter.The appearance material space of adjacent two blade gradually increases, and avoids the accumulation of material.
In one optional embodiment of the present embodiment, by pan feeding to the direction that discharges, each spiral spacing is relative to previous
The increment value of individual spiral spacing is identical value, and each blade is identical relative to the increment value of previous blade diameter
Value.That is, B-A=C-B=D-C=E-D=F-E, b-a=c-b=d-c=e-c.The appearance material space uniformly increased can make material uniform, slow
Slow expansion, reduce material winding risk.
In one optional embodiment of the present embodiment, spiral spacing increment value is the 0.0125 ~ 0.075 of master screw spacing
Times, the increment value of blade diameter is 0.01 ~ 0.06 times of rule blade diameter.That is, B-A=C-B=D-C=E-D=F-E=(0.0125
~ 0.075) A, b-a=c-b=d-c=e-c=(0.01 ~ 0.06) a.Preferably, B-A=C-B=D-C=E-D=F-E=0.0625A, b-a
=c-b=d-c=e-c=0.04a .Hold the too small no positive effect of material space increase, increase easily causes greatly very much top-heavy unreasonable
Drive mechanism, and moment of torsion increase and accessory size increase, it is unreasonable, uneconomical.
In one optional embodiment of the present embodiment, each independent blade radially, it is gradual by edge to center, thickness
Increase.As shown in cutting line region in Fig. 3, blade section is trapezoidal.The rigidity of blade is added, service life increases.Defeated
When sending material, shaftless screw body 3 will not be extruded so that lifting, and when putty occurs, blade will not deform.The present embodiment is not
