MILKING UNIT Russian patent published in 1998 - IPC

FIELD: agriculture, in particular, mechanized cow milking equipment. SUBSTANCE: milking unit has teat cups, main and auxiliary milk claws, pulsators connected in series, milk collector and is further provided with milk attachment having hollow piston, which is communicated via air duct with atmospheric pressure chamber of pulsator. Piston is connected through tie-rod with rotary bucket. Piston cavity is communicated via two radial openings with atmosphere and milk collector cavity, respectively. At the initial stage of milking, main and auxiliary pulsators operate in synchronism to provide microvibrations of teat sleeve stimulating lactation and preventing teat cups from sliding on teats. During major milking time, milking unit operates in normal two-cycle milking mode, but as milk yield is reduced, delivery of milk into milk collector is decreased and, as a result, main and auxiliary pulsators operate in synchronism in a manner similar to operation at the initial stage of milking. EFFECT: increased efficiency, simplified construction and improved milk yield. 3 dwg
