Abstract

FIELD: agriculture.SUBSTANCE: invention relates to agriculture, in particular, to milking plants. Milking cup comprises housing (2) with opening (3) for communicating atmospheric pressure chamber (4) with atmosphere, branch pipe (12) for sucking milk from subcutaneous chamber (8), branch pipe (11) for periodic suction and inlet of air into inter-wall chamber (6), nipple rubber (7), upper and lower parts, tightly attached to housing, resilient tubular shell (5) and metal guide (9). To the metal guide the current-conducting resistance wire (10) is connected from the electric current source for electric heating of the teat cup to the temperature of the calf's oral cavity.

Description

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

Known for a milking cup containing an elastic tubular shell with the same stiffness along the entire length, the upper and lower edges are circularly tightly attached to the body, having a hole for communicating the atmospheric pressure chamber with the atmosphere, a guide located in the inter-wall chamber, a pipe for sucking milk from the suction cup, a pipe for periodic suction and air inlet into the interstitial chamber, nipple rubber, the upper and lower parts tightly circular attached to the body [1].

This milking machine does not provide complete milk removal and injures the nipples of the cow's udder.

The closest technical solution is a milking cup containing an elastic tubular shell, the upper and lower parts of the circular tightly attached to the housing, having a hole for communication of the atmospheric pressure chamber with the atmosphere, a metal guide, a pipe for sucking milk from the suction cup, a pipe for periodic suction and inlet air into the interstitial chamber, the nipple rubber, the upper and lower parts are attached circularly tightly to the body, conductive is attached to the metal guide the first resistance wire from the electric current source for electric heating of the teat cup to the temperature of the calf's oral cavity [2], which is taken by the authors as a prototype.

However, this milking cup does not provide full milk removal and protection against trauma to the nipples, in particular, the four lobes with the nipples of the udder of the cow are not developed uniformly, which entails the injury of the nipples emptied by the lobes by a single mechanical sucking during the suction of milk from the other three nipples by the other three milking glasses.

The purpose of the invention is to ensure the completeness of milk removal and eliminating the likelihood of injury to the nipples during machine milk removal.

This goal is achieved by the fact that an insert with a transparent tube for observation and a ball valve to stop suction are added to the nozzle for sucking milk from the suction cup, designed to disconnect the emptied udder with the nipple from the general process of milk removal.

The figure 1 schematically shows a General view of a milking cup with a nipple.

The milking cup connected to the nipple 1 contains a housing 2 with an opening 3 for communicating the atmospheric pressure chamber 4 with the atmosphere, a nozzle 12 for sucking milk from the suction cup 8, a nozzle 11 for periodically sucking and letting air into the interstitial chamber 6, nipple rubber 7, the upper and lower parts round tightly attached to the body 2, and an elastic tubular shell 5, round tightly attached to the upper and lower parts of the body 2, the guide 9 connected to the electric wire 10, is inserted into the pipe 12 for suctioning milk a transparent tube 16 to it is attached a ball valve 13 connected to the handle 15 of a ball valve and in the sequel a transparent tube 14.

The proposed milking cup works similarly to the prototype [2] with respect to mechanical effects on the nipple 1, but with the following addition. In the process of operation of the milking machine, four milking cups act on the nipples of the udder of the cow, carrying out milk removal. It is known that all four lobes with nipples are not developed equally, and usually the anterior lobes are empty earlier. Until the entire udder is completely emptied, the empty lobes through the nipples undergo idle sucking, which leads to injury to the udder of the cow as a whole, causing mastitis and culling of the cow. To prevent this, we introduce the following addition to the prototype design: sequentially transparent tubes 14 and 16 are attached to the milk suction nozzle 4, between them a ball valve 13 with a handle 15. In the process, the machine milking operator, observing milk removal by the milking machine, seeing the cessation of milk flow through transparent nozzles 14 and 16, the ball valve 13 closes the handle 15, thereby the emptied portion is not exposed to idle sucking a separate milking glass. The proposed device can practically be implemented in commercially available milking machines.
