Abstract

The invention relates to a back tool which consists of several wire loops (3 or 4) arranged like a basket at one end (2) of an axle pin (1). In order to achieve better mixing of the material to be felled, it is proposed that at least one wire loop (3) have the longitudinal struts (7) running essentially in the direction of the axle pin (1) meandering transversely to the direction of rotation.

Description

The invention relates to a rest:> esen according to the Preamble of claim 1.

Such a whisk is known from GB-PS 9 77 761. To improve the work result are In this known whisk the wire loops with their planes not parallel to the axle pin, but arranged inclined.

By the US-PS 43 34 789 is a Mix and Knctwerkzeug known, which consists of a wire helix, one end of which is at the upper end of an axle pin is attached and extends over 360 ° to the lower end of the axle pin where its other end is attached is. The wire helix thus extends to the sides away from the axle pin and is thus able to do so to grasp processing material everywhere in the stirred tank.

From FR-PS 23 47 968 is still a mixer known, which is used to mix granular or powdery material with other ingredients. this device has an S-shaped stirring hook, the loops are rectangular. So that extends This stirring hook also moves to the sides with respect to its axis of rotation and is capable of the one to be processed Easy to grasp across the full width of the mixing container.

The invention is based on the object of designing a whisk of the type described at the outset in such a way that that an even better mixing of the whipped material takes place, so that a significant shortening of the Working time is possible.

The object set is achieved according to the invention by the features indicated in the characterizing part of claim I. specified features. The meandering shape of the longitudinal strips results in a greater effective length the wire loops, so that a larger amount of the material to be cut is captured with each rotation of the whisk will.

According to one embodiment of the invention, a further improvement of the work result is achieved by that the meander loops of the individual longitudinal struts are offset from one another in the axial direction. Due to such a height offset of the meander loops In the various longitudinal struts, other particles of the material to be felled come with them again and again in contact and are thereby included in the striking process.

Also in that alternating meander loops and smooth longitudinal struts are provided, the radius of the smooth longitudinal struts between the inner and outer radius of the meander loops there are always other particles with the

Wire loops in contact. A radially inwards into the whisk

Directed movement of the material to be felled is achieved in that the internal meander loops are opposite the external ones are reset in relation to the direction of rotation.

A strong vortex formation on the wire loops and

thus a good mixing of the air under the Schlaggut is achieved in that the wire loops used beam is edged.

Based on an exemplary embodiment shown in the drawing, the subject of the application is

jo described in more detail below. It shows

1 shows a whisk in which meander loops are formed on the longitudinal struts of a wire loop are,

Fi g. 2 a single wire loop in which the meander

the loops of the two longitudinal struts are offset from one another in the axial direction,

3 shows a whisk in cross section, in which the Longitudinal struts of one wire loop are smooth and those of the other are meandering and the radius the smooth longitudinal strut lies between the two radii of the meander loops,

F i g. 4 shows a whisk in cross section, in which the inside meander turns set back compared to the outside seen in the direction of rotation are,

F i g. 5 other forms of meander loops,
Fig. 6 Cross-sectional shapes of the wire used for the whisk.
In Fi g. 1, 1 denotes an axle pin, at one end 2 of which two wire loops 3 and 4 offset by 90 "are arranged. With its other end 5, the axle pin can be inserted into the drive opening of an electric agitator Meander loops 8 are formed on the longitudinal struts 7. The wire loop 5 lying perpendicular to the plane of the drawing can have smooth or also meander-shaped longitudinal struts 7. The longitudinal struts 7 are connected by transverse struts 9 at the lower end.

bo In the embodiment shown in Fig. 2 a Wire loop 3 are the meander loops 8 of the left and right longitudinal brace 7 axially offset from one another. The offset can be the full height or one Part of the height of a male elbow 8 corresponds. If two wire loops 3 and 4 with meandering longitudinal struts 7 are provided for a whisk, so both the meander loops 8 of a wire loop 3 against each other and against the

Meander loops of the other wire loop 4 can be axially offset.

When combining a wire loop provided with meandering longitudinal struts 7 with a wire loop 4 having smooth longitudinal struts 7 according to FIG. 3, it is appropriate that the dimension of the radius R 1 of the smooth longitudinal struts between the dimensions of the outer and inner radius R 2 and Λ 3 of the meander loops 8 of the other wire loop 3 is. In this way, the parts of the material to be felled that are not grasped between the meander loops 8 are then grasped by the longitudinal struts 7 of the other wire loop 4. This results in a better mixing of the material to be felled.

According to the illustration in FIG. 4, the meander loops 8 are bent with their inner turns by an angle λ with respect to the plane of the wire loop 3 with respect to the working direction of rotation. Due to this inclination of the plane of the meander loops 8, a radially inwardly directed force is exerted on the material to be cut, so that it is conveyed in the transverse direction and thus repeatedly conveyed into the area of the whisk.

F i g. 5 shows two further design variants of the meander loops 8.
