Usage requirement registration. Compulsory mixer with ring-shaped mixing chamber.

Pan mixers with a flat mixing base can use the middle part of the Only use soil with a great deal of technical means for mixing, as is the case with mixers with one or more mixing stars the lall is, in which not only the mixing container and the mixing stars revolve, but also the blades inside the star make a turn of your own. In another design, the middle part of the miseh floor is cylindrical Insert filled out in which the drive motor is housed. However, the annular misery space formed in this way has poor accessibility to the engine and the drive parts and also one result in considerable effort.

The compulsory mixer according to the present invention combines the advantage the ring-shaped mixing chamber with a simpler structure and significantly reduced wear on the container and the agitator.

The blades are preferably arranged in pairs, so that a Msafe of the type according to the invention e.g. 2 outer scrapers, 2 guide vanes and has 2 inner scrapers, although other arrangements can exist depending on the mixer size.

The Misehschaufein can be resiliently mounted in a manner known per se. However, it is a feature of the invention that the blades in any combination are designed to be pivotable about a vertical, horizontal or inclined axis. The latter arrangement has the advantage that the shovel in question does not only stand out from one of the wall parts, but at the same time, for example, from the circumference and in front of the floor when the shovel has to give way due to clamps. Another feature of the invention is the forced movement of the blades to lift them off the container wall, so that any jammed mix pieces are released again. Within a group of blades of the same type, e.g. outer scrapers, the blades are expediently lifted off in such a way that their paths running close to the wall intersect on the? / And so that the following blade is only within the path of the previous one.

screaming shovel hit the wall.

The guide devices for lifting the rotating blades can be attached to the perimeter of the container, but the grinding distance of each shovel always the same steepness of the container wall hit and wear them unevenly.

According to the invention, it is more expedient to use the guide devices as cams or the like to be attached to a rotating part which has a relative speed with respect to the blade carrier, that is to say with respect to it this leads or lags behind, so that the paths of the blades approaching the wall overlap on the circumference of the container hike.

Another feature of the invention is the use of the middle part of the container as a closure member of the then central emptying opening, which, in contrast to the flat slide in the Kingzone, is large Insensitivity to pivoting is reached. Opening the central emptying opening can also be achieved by lowering the container in relation to the central part, or by lifting and lowering in opposite directions these parts are effected.

Furthermore, according to the invention, the mixer is for special circumstances Executable with a conical bottom and a cylindrical or conical middle part, partly to achieve better tree utilization, partly Easy emptying of the meat without much effort on shovels to achieve.

The drawings show exemplary embodiments.

The unimportant components of a Mixers, such as the loading device and chassis, have been omitted.

Figure 1 is a plan view and Figure 2 is a cross section through one Mixer according to the invention. This 1 is the outer land of the lischbehält ers with the bottom 2 and the inner round insert 3. The Motor 4 drives the blade carrier, possibly via a gearbox with the scraper blades 6,7 and 8,9, as well as the Leitsehaufein 10.11. Depending on the intended effect, these blades are vertical

Axles 12, inclined axes 12 ^f or horizontal axes 13 pivotably mounted and provided with return springs as required.

FIG. 3 shows the mixing container as a plan view and FIG. 4 as a cross section with outer wall 1, floor 2 and inner part 3, simplicity only with 2 blades for the sake of clarifying the idea of the invention, for example "Above the blade carrier 5 is the drive wheel 14 attached to the drive shaft of the blade carrier. The wheel 14 drives with the wheels 16, 17 via the intermediate shaft 15 The wheel 18 on the lock carrier 19 with the holes 20 for moving the shovel arms 21 and the crook 22 for moving the shovel arms 23.

The translation of the drive of the Uockenträgers 19 is chosen so that the latter is faster or slower than the blade carrier 5 rotates so that the locHen 20,22 during one vane revolution Lift the shovels off the wall and floor at least one or more times to release jammed stones. * So it cannot it can happen that jammed stones attack the walls over the full circumference.

In Figure 5, the inventive design of the central part of the Mixing container shown as an emptying device. The middle part 24 can be raised and lowered in the guides on the mixer parts 27 by means of the pinion 25, which engages in the axle 26. For the easier Insertion into the central emptying opening in the bottom 2 is the lower edge of 24 slightly tapered or beveled. Below the Bottom 2 can, as indicated by dashed lines, a further guide of the Axis 26 or the middle part 24 may be provided. It is without further explanation understandable that the opening and closing also by lowering the mixing container: or by counter-rotating between Outer part and central part of the mixing container can be reached.

As a further example, FIG. 6 shows the mixing container with a conical. Bottom, whereby the middle part can be cylindrical or also conical
