Description

einer kreisringfönnigen Außenwand 3 und einer ebenfalls kreisringförmigen Innenwand 4.a circular ring-shaped outer wall 3 and a likewise circular ring-shaped inner wall 4.

In dem durch die Innenwand 4 gebildeten zentralen Innenraum 5 ist die Antriebseinheit mit einem Antriebsmotor6 und einem Getriebe? angeordnet, aus dessen Gehäuse oben die lotrechte Mischwerkswelle 8 austritt.In the central interior 5 formed by the inner wall 4, the drive unit is with a Drive motor6 and a gearbox? arranged, from the housing above the vertical mixer shaft 8 exits.

im kreisringförmigen Ringtrog 1 laufen, wie angedeutet, Mischwerkzeuge 9 und 10 um, welche zum Teil den Doden 2, zum Teil die Außenwand 3 des Ringtroges 1 bestreichen.run in the circular ring trough 1, as indicated, Mixing tools 9 and 10 around, which partly the dodes 2, partly the outer wall 3 of the Spread the ring trough 1.

Die Mischwerkzeuge 9,10 sind an den freien Enden von Mischwerkzeugannen 11 und 12 angebracht, die ihren Ausgang von einer Glocke 13 nehmen, welche auf die Mischwerkswelle 8 aufgesetzt und mit dieser verbunden ist.The mixing tools 9, 10 are attached to the free ends of mixing tool trays 11 and 12, which take their exit from a bell 13 which is placed on the mixer shaft 8 and is connected to it.

Um den Mischwerkzeugen 9, 10 r^e Möglichkeit zu geben, in genügender Weise auszuweichen, ist zwischen dem festen Maschinengestell und dem Teil der Maschine, welcher die Werkzeuge und den Antrieb derselben umfaßt, ein elastisches Zwischenlager 18 geschaltet, das wie bei der dargestellten Ausfiihrungsform kreisförmig ausgebildet sein und quadratischen Querschni.: aufweisen kann. Dieses Zwischenlager 18 stützt sich einerseits auf einer kreisringförmigen Platte 19 ab, welche fest mit dem Maschinengestell oder sonstigen feststehenden Teilen, z. B. der Innenwand 4 des Ringtroges 1, verbunden ist, uäd andererseits an einer ebenfalls kreisringfönnigen Platte 20, welche mit dem Antriebs- und Werkzeugteil der Mischmaschine fest verbunden ist, z. B. mit dem oberen Flansch 21 des zwischen Antriebsmotor 6 und Mischv. i kzeuge 9,10 geschalteten Getriebes 7.To the mixing tools 9, 10 r ^ e possibility to give, to evade sufficiently, is between the fixed machine frame and the part the machine, which includes the tools and the drive thereof, an elastic intermediate bearing 18 switched, as in the illustrated embodiment be circular and have a square cross-section. This interim storage facility 18 is supported on the one hand on an annular plate 19, which is fixed to the Machine frame or other fixed parts, e.g. B. the inner wall 4 of the ring trough 1 connected is, and on the other hand on a likewise circular ring-shaped plate 20, which is connected to the drive and Tool part of the mixer is firmly connected, for. B. with the upper flange 21 of the between the drive motor 6 and Mischv. i tools 9,10 switched Transmission 7.

The invention relates to a compulsory mixer for being able to give way, whereby the alternative option of building materials with a ring trough, in which the mixing mechanism j _n rotate in a vertical and horizontal direction through tools on a vertical mixing mechanism shaft, is made possible by pivoting around the drive point, which is via an in the interior of the Ring trough arranged- In detail, mixing paddles or scraper gears must be driven, which in turn is connected to their circulation via similar tools, which brush the inner surfaces of the vertical flange with the inner wall of the ring trough on the right-hand side of the trough. generally unavoidable low
