  • Mixing machine
    Patent number: 4834549
    Abstract: A mixing machine has a rotor which can be displaced along an axis. The rotor and its drive shaft are rotatably supported by a casing and a cylindrical shaft respectively. A motor for driving the rotor is mounted on a support connected to the end of the cylindrical shaft. The cylindrical shaft can be displaced along the axis. At the lowermost position, holes in a plate of the casing communicate with a discharge port in the structure supporting the cylindrical shaft, whereby rotation of the rotor forces the tank contents out the discharge port.
