APPARATUS FOR AUTOMATIC DETACHMENT OF MILKING UNIT Russian patent published in 2003 - IPC

FIELD: animal farming. SUBSTANCE: apparatus has drum mounted on frame, cord wound onto drum and joined through connecting member with suspension part of milking unit, pneumatic engine and rotor eccentrically mounted in pneumatic engine casing and provided with blades positioned for contacting with surface of rotor chamber. Pneumatic engine is connected through reducing transmission to drum. Rotor of pneumatic engine has axial pneumatic channel, and blades are made curved and are pivotally connected with their one ends on its surface. Friction-type reducing transmission has conical contacting members formed, respectively, on drum internal surface and on roller fixed on splined joint pin. Pneumatic chamber has flexible member and is divided by elastic membrane into two parts, one of parts being fixed on rotor shaft end and communicated with internal cavity of pneumatic channel and other part being equipped with splines and communicated with atmosphere. Splined joint pin is positioned in pneumatic chamber splines for axial movement and is connected with its end to elastic membrane. Apparatus is adapted for detachment of milking unit from animal's udder upon termination of milking process. EFFECT: increased efficiency, reduced animal care time and decreased labor intensity. 4 cl, 5 dwg
