Description

(54) MILKING GLASS

one

This invention relates to the field of agriculture, in particular to teat cups.

The known teat Cup, including the body with the nipple rubber located in it, does not provide the necessary milking mode 1.

A milking cup is also known, which includes a housing with nozzles and an elastic tube with a suction cup located therein, which has elastic protrusions located on its inner wall in a podskoskovoy chamber 2.

The known teat cup does not eliminate the detrimental effect of the vacuum on the nipple of the animal.

The purpose of the invention is to reduce the detrimental effect of vacuum on the nipple by injecting air into the spouting chamber during the compression stroke.

This is achieved in that in the wall of the elastic tube above the elastic protrusions there are holes with a valve fixed on the inner wall of the elastic tube.

The valve is designed as a cuff.

Elastic protrusions made in the form of segments.

1 shows a teat cup with a sucking stroke, a longitudinal section; in fig. 2 - the same glass during the compression stroke; in fig. 3 shows a section A-A in FIG. in fig. 4- section BB in FIG. 2; in fig. 5 - elastic tube.

The teat Cup includes a housing 1 with nozzles 2 and 3 and an elastic tube 4 with a suction cup 5 located therein, having elastic protrusions 6 located on its inner wall in a podskoskoe chamber 7. In the wall of the elastic tube 4 above the elastic protrusions 6 there are holes 8 with a valve 9, fixed to the inner wall of the elastic tube 4. The valve 9 is made in the form of a cuff. Elastic protrusions made in the form of segments. The housing 1 consists of a rigid tube 10, equipped with a tip 11 adjacent to the suction cup 5, and a tip 12 with nozzles 2 and 3. Located in the tip 12 part of the nozzle 3 is a viewing cone.

Works milking cup as follows.

During the stroke, the suction of the elastic tube 4 is stretched, the valve 9 closes and milk is withdrawn from the nipple through the opening formed by the expanding segments. During the stroke, the compression of the elastic tube 4 under the action of the vacuum in the podsoskoy chamber 7 is compressed, the segments approach each other, forming a narrow channel, the valve 9 opens, and atmospheric air flows through the piping 8, which can be spread on the elastic tube 4 asymmetrically, into the podskoskovoy chamber 7, in which atmospheric pressure can be generated. Further, the operation cycle of the teat cup is repeated;

This mode of operation of the teat cup reduces the harmful effects of vacuum on the nipple of the animal.
