Device for converting a linear movement in a stationary system into a rotational movement about a pivot axis in a system which rotates about a rotational axis

A mixing device comprising

• a container for receiving mixing material, which is rotatable about a container axis and in the bottom of which is arranged an emptying opening, a closure cover for closing the emptying opening and a mixer foot, the container being rotatable relative to the mixer foot;
• and
• a conversion device for converting a linear movement in a stationary system into a rotary movement about a pivot axis in a rotating system which rotates about an axis of rotation, wherein the pivot axis and the axis of rotation are not identical and do not extend parallel to each other, comprising a lift element, a lift device with which the lift element can be moved with a translatory movement relative to the stationary system, and a device for converting a linear movement into a rotary movement, wherein the lift element has a first lift element portion and a second lift element portion, wherein the two lift element portions are connected together by way of a rotary bearing in such a way that the first lift element portion can be rotated relative to the second lift element portion about the axis of the rotary bearing, wherein the two portions of the lift element are connected together in positively locking relationship in the direction of the translatory movement of the lift device, wherein the first lift element portion is connected to the lift device and the second lift element portion is connected to the device for converting a linear movement into a rotary movement, wherein the device for converting a linear movement into a rotary movement is connected to a shaft positioned on the pivot axis in such a way that a linear movement of the second lift element portion is converted into a rotary movement of the shaft about the pivot axis, wherein the device for converting a linear movement into a rotary movement has a cam plate connected to the second lift element portion and a lever which is in contact with the cam plate and which is connected to the shaft,
• wherein the mixer foot is part of the stationary system and the container is part of the rotating system, and
• wherein the closure cover can be rotated about the pivot axis for opening and closing the emptying opening.
