- a plurality of mixing vanes 16 are fastened to the shaft 12, which take over the actual mixing of the supplied components. It is understood that the number of mixing blades 16, their axial distance from one another and their angular arrangement with respect to the axis of rotation A can be chosen differently than shown, in order to adapt the mixing device 10 to different needs.
- FIGS. 2 to 6 one of the mixing vanes 16 is shown enlarged in different views in a state removed from the shaft 12.
- the mixing blade 16 has an annular base 20, which is provided with an axial through-passage 22, which here has a substantially polygonal profile.
- the shaft 12 is at least in the area
- a base body 24 which extends radially outward with respect to the base 20 and has a wedge-shaped cross section (see in particular FIG. 6).
- the cross section of the basic body 24 is substantially triangular, with the area enclosed by the triangular shape increasing with increasing radial distance from the base 20 (see in particular FIG. 4).
- the base body 24 has a wedge tip 26, which is rounded here, and points in the direction of a preferred direction of rotation R (see FIG. 1). Spatially seen, the contiguous arrangement of the wedge tips 26 of all cross sections of the basic body 24 in the embodiment shown forms a straight line (see FIG.
- this arrangement of the wedge tips can also have a concave or convex course or can be joined together by several be formed subsequent straight sections with different pitch.
- different straight line sections can be connected to one another by curved transition regions.

- the mixing blade head 28 may also be diamond-shaped, i. form a two-directional wedge, in particular when the base body 24 has a diamond-shaped cross-section.
- Both the base body 24 and the mixing blade head 28 expand, starting from the associated wedge tip 26 or 30, in the axial direction of the shaft 12, ie Both the base body 24 and the mixing blade head 28 in the axial direction of the shaft 12 is always wider, if one moves from the associated wedge tip 26 or 30 in the circumferential direction over the main body or mixing blade head.
- this extension is more pronounced in the axial direction in the mixing blade head 28 than in the base body 24, so that transition regions 36 are formed between the narrower base body 24 and the wider mixing blade head, each connecting a side surface of the base body 24 with the associated bottom of the mixing blade head 28.
- these transitional regions 36 are wedge-shaped and present on both sides of the mixing blade 16, but only such a transition region can exist if, for example, the mixing blade head 28 widens only on one side with respect to the main body 24, starting from its wedge tip 30 .
- the extension of the base body 24 and mixing blade head 28 is symmetrical, ie, mirror image with respect to a center line X (see FIG. 5), but the extent of extension from the base body 24 and / or mixing blade head 28 in the axial direction on both sides of the body 24 may be different.
- the transitional area 36 widens, starting from the wedge tip, to a rear edge 38 of the mixing blade 16 and is also inclined with respect to the axis of rotation A of the shaft 12 such that a shaft 12 rotating in the preferred direction of rotation R is to be mixed Good from the transition region 36 inwards, ie is pushed or promoted to the rotation axis A.
- the transitional regions 36 also spread laterally apart the material to be mixed, i.
- the material to be mixed is intensively “swirled” with a rotation of the mixing blades 16 and pushed radially inward to the shaft 12, wherein the centrifugal forces caused by the rotational movement of the mixing device 10 in the estate centrifugal movement of the Guts radially outside, which further intensifies the mixing and thus improves.
- mixing rod 40 can thus by simple axial displacement of one of the two mixing blades 16 involved on the shaft 12 ein ⁇ set or removed again.
- mixing rods 40 can also be arranged between further pairs of axially aligned mixing vanes 16, and with a corresponding radial extent of the base body 5, a plurality of mixing rods 40 can be axially aligned with one another at different radial distances from the shaft 12 between a pair Blend be 16 angeord ⁇ net.
- a modified embodiment of a mixing blade lo 16 is shown in various views, extending from the embodiment shown in Figures 3 to 6 mainly by a widening from the wedge tip 30 on both sides widening mixing blade head 28 and with respect to the axis of rotation A more inclined transition areas 36 different.
- many modifications i5 are possible within the framework of the mixing-wing concept presented here, of which only two are shown.
- the mixing vanes 16 can be made entirely of plastic, for example of suitable polyethylene or polytetrafluoroethylene, if the stability requirements can be met with such an embodiment. This will be particular
- each mixing blade 16 may have a metal core (not shown) coated with a plastic.
- each mixing blade 16 can also be made completely of metal, e.g. cast steel.
- FIG. 11 shows a modified mixing device 10 intended for use in a mortar mixing pump, in which a worm 44 is arranged on the shaft 12 instead of the conveying vanes 14 of the first exemplary embodiment described above.
- the screw 44 conveys the solid component of the mortar mixture into the intensive mixing zone formed by the action of the mixing vanes 16, in which the liquid component (water) is added, and prevents the liquid component from entering the storage area of the solid component.
