DEVICE FOR AUTOMATIC REMOVAL OF MILKING MACHINE Russian patent published in 2014 - IPC A01J5/17 

FIELD: agriculture.

SUBSTANCE: device comprises a pneumatic motor (1) fixed to the frame with a drum (2) and a cord (24) wound on it with the connecting element (25). In the housing of the pneumatic motor a rotor shaft is eccentrically mounted with curved blades hingedly connected at one end. The rotor shaft is mounted on two bearings that are located in the lid (17) and the housing. The housing has an inlet element for the atmosphere, connected with the rotor chamber through the inlet channel (19). The rotor shaft is connected to the drum through the friction reduction gear having a pneumatic chamber that is divided by an elastic membrane into two parts. One part of the pneumatic chamber is rigidly attached to the rotor shaft and communicates by the interior cavity with the pneumatic channel. Another part of the pneumatic chamber is connected with its cavity to the atmosphere. The shaft of spline connection is installed in splines of the pneumatic chamber with the ability of axial movement. One end of the shaft is attached to the elastic membrane. Frictional contact elements in the free position are open. The curved blades in the lower part on the side facing the rotor shaft are formed with recesses. In the recesses the elements of permanent magnet are mounted so that to prevent them from direct contact with the walls of the cylindrical rotor chamber during operation. The rotor shaft is made of nonmagnetic material. The cylindrical rotor chamber housing is made of magnetic material.

EFFECT: reduced air consumption.
