Abstract

FIELD: agricultural engineering, in particular, milking equipment.

SUBSTANCE: transformable teat cup has casing, sucker arranged inside casing and composed of case with upper bead and flexible tube fixed to wall protruding to the inside of case. End part of flexible tube has thickened portion with two annular grooves and is equipped with milk pipe having corrugated portion. Milk pipe is fixed on lower end part of casing. At least one additional annular groove is formed on thickened portion of flexible tube and adapted for attachment of end part of flexible tube in operating state to sucker upper bead, depending upon size of cow's teat, and for defining low pulsing vacuum pressure chamber so that during milking procedure, thickened portion surface and flexible tube surface act upon cow's udder and teat in the region adjoining teat base.

Description

The invention relates to agriculture, in particular to equipment for machine milking animals.

A single-chamber milking cup is known that contains a sleeve with a suction cup located on it, consisting of a body with a top shoulder and a flexible tube fixed to the wall protruding inside the body, the end portion of which has a thickening with two annular grooves (SU 1544300 A1, 02.23.1990).

The disadvantages of the known milking cups are as follows:

- the process of milking milk occurs at significantly higher values of vacuum pressure: more than 33 kPa, there is no effect of massage on the nipple of the cow, which leads to trauma to the nipple of the cow, getting into the milk during trauma to the nipple, and with it infection, which, in turn, leads to to reduce the quality of milk;

- atmospheric pressure is applied to the suction cup cavity (chamber) of the glass, which adversely affects the nipple sphincter and the nipple milk flow, since during the milking process the sphincter continuously opens and closes, and when the atmospheric pressure is applied, the milk is foamed under pressure, overflow of the sleeve of the teat cup, which, in turn, leads to the backflow of foamed milk from the cow’s nipple (in this case, the cow experiences “stress” - pain sensations, since by nature when suckling milk by the calf, the process of milk flow is continuous and as soon as possible without creating conditions of back pressure from the side of the calf), therefore, the milk flow cycle increases, which leads to a dissonance between the ability to milk the cow and the capacity of the milking cup. As a result, overexposure of the teatcup on the nipple of the cow occurs and, as a result, this leads to mastitis and other diseases.

The technical result achieved during operation of the declared transforming milking cup is to reduce the trauma of the nipples of the cow during milking, maintaining the quality of the milk obtained and to increase the usability of the milking cup.

The specified technical result is achieved by the fact that in the transforming milking cup containing a sleeve (12) with a suction cup located on it, consisting of a body (1) with an upper flange (4) and a flexible tube (3) fixed to the wall protruding inside the body, the end section which has a thickening with two annular grooves (4, 5), and at the other end is installed having a corrugated section (11) tube for the passage of milk (13); at the thickening of the flexible tube (3), at least one annular groove (4, 5) is additionally periodically made at the same interval for fastening the end portion of the flexible tube in working condition on the upper flange (4) of the suction cup, depending on the size of the cow’s nipple ( 17) and with the formation of a second chamber of low pulsating vacuum pressure and so that during milking the thickening surface (4, 5, 6, etc.) and the inner surface of the flexible tube (3) act on the surface of the udder and nipple of the cow in the area nipple bases; the suction cup is equipped with a stopper plug (15) and has a low pulsating vacuum pressure tube (16) mounted on the suction cup body, one end of which is connected to the low pulsating vacuum pressure chamber (8) and the other to the sleeve tube (9) (12) made with the possibility of connecting to a source of low pulsating vacuum gauge pressure; moreover, the inner diameter of the tube for the passage of milk is at least 14 mm; adjustable vacuum gauge pressure (18, 10) supplied to the suction cup (17) and pulsating vacuum (8) of the chamber is 7-33 kPa; and the sleeve, the suction cup, the tube for the passage of milk, the tube of a low pulsating vacuum are made of lightweight transparent plastic.

Such a constructive implementation of the claimed single-chamber milking cup allows the user to eliminate the disadvantages indicated above and to achieve the above technical result, since the milking process occurs with a pulsating vacuum of 7-33 kPa, the presence of additional grooves on the thickening of the flexible tube of the suction cup (which allows the use of a milking glass at any size along the length of the nipple of the cow), a tube of pulsating low vacuum pressure, a vacuum chamber in a suction cup formed by a flexible a tube with additional grooves in the thickening (there is no atmospheric pressure supply to the suction cup (chamber) cavity, and an adjustable low vacuum pressure of 7-33 kPa is supplied), it is possible to provide a cow udder and nipple massage in the area of the nipple base during milking, which eliminates trauma to the nipples of the cow and overexposure of the teat cup on the nipple, while ensuring a more complete outflow of milk from the nipple tank while maintaining the quality of the milk. The presence of a stopper plug and a corrugated portion on the milk passage increases the usability during milking, eliminates the ingress of foreign objects into the milk when milking, at least 14 mm inner diameter of the milk passage eliminates the turbulent nature of milk movement (therefore, foaming is excluded ) The implementation of the transforming milking cup from lightweight transparent plastic (at the same time its weight is reduced by 3-4 times) eliminates trauma to the nipples of the cow during milking from the dynamic effects of the milking cup and 100% visual observation of the return of each cistern of the milk udder and the operator’s quick response to overexposure of a teatcup in each quarter of the mammary gland.

The invention is illustrated by drawings, in which Fig. 1 shows a single-chamber milking cup, in Fig. 2 - a suction cup with a flexible tube and a stopper, in Fig. 3 - conjugation of the lower thickening groove with a shoulder (1st transformation), in Fig. 4 - (2nd transformation) same, upper groove.

The transforming milking cup contains a suction cup (1) having a wall protruding into the interior of its cavity and a flexible tube (3) fixed in its middle part (2). The end section of the flexible tube (3) has a thickening, on the outer wall of which annular grooves (4-6) are made (or more, if necessary, depending on the size and shape of the nipple). The shape and size of the grooves (4, 5) correspond to the shape and size of the shoulder (7) made in the upper part of the suction cup. In working condition, the flexible tube (3) forms with the inner body of the suction cup a chamber (8) of low pulsating vacuum pressure. The suction cup (1) is mounted on the sleeve (12) and has its pulsating low vacuum tube (16) attached to the body, which exits in the upper part into the pulsating vacuum chamber (8) (7-33 kPa), and is fixed on the tube with the lower part ( 9) monolithically strengthened with a sleeve (12) of a teatcup; a tube (13) with a corrugated section (11) is attached to the lower part of the sleeve (12) of the milking cup for supplying an adjustable vacuum of 7-33 kPa (18) and transporting milk. A stopper plug (15) is installed on the suction cup to protect the animal from air and sewage during milking in the milking system.

Transforming milking cup works as follows. When milking cows, the glass is placed on the nipple of the cow and the surface of the flexible tube (3) is in close contact with the body of the nipple and the udder in the area of the base of the nipple (14), producing a massage effect during milking under the influence of a low pulsating vacuum pressure of 7-33 kPa (such the same as the calf produces in nature when sucking milk from a cow’s nipple), trauma to the nipples of the cow is excluded, and milk is more completely out of the nipple’s tank.
