DEVICE FOR AUTOMATED CONTROL OF THE MILKING PROCESS BY QUARTERS OF THE UDDER OF A COW Russian patent published in 2022 - IPC A01J5/00 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture, in particular to devices for milking cows. On each milk pipe of the teat cup there is a controlled valve mechanism, consisting of an inlet pipe connected to the milking cup, an outlet pipe with an electromagnetic coil installed on it, and an annular body. In the middle part of the body there are holes for the passage of milk. In the central part of the housing, an open bowl-shaped recess with two electrodes fixed in it is located on top. At the bottom of the central part of the body there is a cylindrical guide niche with a spherical dome for accommodating a movable spherical valve made of non-magnetic material. Attached to the bottom of the valve is a bar-shaped neodymium magnet. A neodymium magnet is installed at the top of the niche dome. At the top of the spherical valve there is an element made of a magnetically conductive material. The adhesion force of the magnet and the element is less than the magnetomotive force of the electromagnetic coil acting on the neodymium valve magnet when a voltage of the corresponding polarity is applied. The coil, together with the electrodes, is connected by a cable through an electronic switch to the control unit.

EFFECT: design is simplified, the reliability of the device operation is increased and the efficiency of the milking machine is increased.
