摘要

Mixer (1) has a mixing vessel (3) arranged on a support frame (2). The mixing vessel has a stirring shaft (6) with a stirrer (5) at one free end (4). The mixing vessel lid (7) can rotate and is axially connected to the stirrer shaft. A stirring shaft lifting device (9) connected to the vessel lid via a first extension arm (8) is arranged parallel to the stirring shaft. The lifting device is able to tilt about its vertical axis on the support frame. The first extension arm supports the drive (12) for the stirring shaft on the other free end (11). The lifting device has a second extension arm (14) provided with a counter weight (13) on the side opposite the stirring shaft. Preferred Features: The stirring shaft lifting device is connected to the mixing vessel so that it is resistant to pressure and extension. The lifting device has cylinder-piston arrangement (17) arranged in an inner tube (15) and an outer tube (16), the inner tube being restrained in the outer tube connected to the support frame.
