Abstract

FIELD: agriculture, in particular, milking equipment. SUBSTANCE: teat cup has flexible tubular enclosure. Wall of enclosure has thickness increasing from the top to the bottom. Enclosures of such construction provide complete squeezing of milk from teats of any sizes and may be used in series-produced teat cups. EFFECT: increased efficiency and improved milk productivity. 1 dwg

Description

 The invention relates to agriculture, in particular to milking installations.

 Known for a milking cup containing an elastic tubular shell, the upper and lower edges of a circular tightly attached to the housing having a hole for communication of the atmospheric pressure chamber with the atmosphere, a nozzle for sucking milk from the suction cup, a nozzle for periodic suction and air inlet into the interstitial chamber, nipple rubber , the upper and lower parts around the tightly attached to the body [1].

 This teatcup does not fully squeeze milk from large nipples, especially from nipples longer than 8 cm.

 The closest technical solution is a milking cup, also containing an elastic tubular shell, the upper and lower edges of the circular tightly attached to the housing, having a hole for communication of the atmospheric pressure chamber with the atmosphere, a pipe for sucking milk from the suction cup, a pipe for periodic suction and air inlet interstitial chamber, nipple rubber, upper and lower parts tightly circular attached to the body, which the authors adopted as a prototype [2].

 However, this milking cup does not provide full squeezing of milk from large nipples.

 The purpose of the invention is the provision of full squeezing of milk from nipples of all sizes, increasing labor productivity and animal productivity.

 This goal is achieved in that the walls of the elastic tubular shell are made with thickness increasing from top to bottom.

 The drawing schematically shows a General view of the milking cup.

 The milking cup contains a housing 2 with an opening 3 for communicating the atmospheric pressure chamber 4 with the atmosphere, a nozzle 5 for sucking milk from the suction cup 6, a nozzle 7 for periodically sucking and letting air into the interstitial chamber 8, the teat rubber 9, the upper and lower parts round tight attached to the housing 2, and an elastic tubular shell 1, circularly tightly attached to the upper and lower parts of the housing 2, having walls with a thickness increasing from top to bottom.

 The proposed milking glass works as follows. During operation of the teatcup, the necessary vacuum pressure is maintained in its suction cup 6 and nozzle 5. At the beginning of the suction stroke, air is sucked out of the nozzle 7 and the inter-wall chamber 8 and increasing vacuum pressure is created there, and atmospheric pressure enters through the opening 3 of the housing 2 into the atmospheric pressure chamber 4. At the beginning of the increase in vacuum pressure in the inter-wall chamber 8, the upper part of the elastic tubular shell 1 and the nipple rubber 9 bends circularly inward as much as possible and compresses the base of the nipple 10 from all sides. With a further increase in vacuum pressure in the inter-wall chamber 8, the transverse deflection into the inside of the elastic tubular shell 1 continues from above and at the bottom of the milking cup, the squeezing of milk from the nipple 10 is completed with its suction from the milking cup. During the next final cycle of unloading the teatcup, air from the pulsator (not shown) is supplied through the nozzle 7 to the interstitial chamber 8. The elastic tubular shell 1, the nipple rubber 9 and the nipple 10, under the action of their elastic forces, return to their extreme initial positions, in which air is pushed out of the atmospheric pressure chamber 4 through the opening 3. At the same time, the nipple 10 is filled with milk. Further, the pulsation cycle is repeated periodically under the influence of a pulsator.

 The proposed device can practically be implemented on commercially available milking cups.

 A prototype of the proposed milking glass worked at one dairy farm in the Kabardino-Balkarian Republic for more than a year and showed high results in cow productivity and labor productivity.
