This invention relates to agriculture, in particular to milking methods.

The drawing shows a teat cup.

The teat cup consists of a sleeve 1 (body) and a nipple tube 2 located in it, in which an annular chamber 3 with a flexible elastic wall 4 is installed. The sleeve 1 and the nipple tube 2 form an interstitial chamber 5 with their walls. The cavity of the nipple tube 2 forms a suction

The chamber 6, which can communicate the wall chamber radially squeezes the nipple, which changes its shape and creates a reaction against the wall 4 of the annular chamber 3. This reduces the cavity of the annular chamber and blocks the access of the vacuum into the cavity formed at the side of the nipple tip above the annular chamber 3 , due to the overlap of the nipple tube 2 channel 7.

The decrease in the cavity of the annular chamber 3 causes deformation of the tip of the nipple from top to bottom along the nipple. This contributes to the restoration of blood circulation in this area, with the nasal sphincter closed. At this point, the volume of the cavity of the annular chamber is 1.5 times the volume of this chamber during the Rest cycle.

In tact, the rest in the pre-chamber 6 in the cavity, covered by the annular chamber (under the nipple opening) and the cavity formed by the wall of the nipple tube and the lateral part of the nipple tip, comes under pressure of 755.5 mm Hg. The pressure is 735.5 mm Hg. on the nipple from the side of the interstitial chamber is preserved. By equalizing the radial force pressure on the nipple, its shape is restored. The downward pressure of the nipple tip is reduced. In this case, the cavity of the annular chamber 3 is reduced to its original value, which relieves the surface of the nipple tip from pressure.

with through channel 7 with the upper cavity 8 of the nipple tube 2.

The volume of the cavity of the annular chamber and, therefore, the air enclosed in it at a pressure of 735.5 mm Hg. is 3 cm.

The method of milking using the said teat cup is carried out as follows.

The chamber 3 is placed in the nipple tube 2 so that its elastic wall 4 in which the teat cup is put on the nipple of the animal touches the surface of the nipple tip. The udder is washed and massaged, the first streams of milk are donated. Then put the teat cups on the nipples and working from a variable vacuum source (not shown) with the teat cups to extract the milk from the teats. When created in the grinding chamber 6, a constant vacuum is formed above the annular chamber (below the lateral sides of the nipple tip).

Vacuum comes to this place from the water canal chamber through channel 7. Milk from the nipple enters the spraying chamber. For different diameters of the nipple tube, the initial working volume of gas under atmospheric pressure is 2.5–5.5 cm. This is due to the fact that different gases in structure do not vary in volume under the same conditions. During milking (in the process of sucking ) under the action of vacuum in the spraying chamber, the volume of the cavity of the annular chamber increases, its wall 4 slightly upwardly opposes the downward movement of the nipple and, covering the tip of the nipple, protects it from the effect of vacuum. The pressure created by the nipple of the animal wall 4, slightly

Claims (1)

Invention Formula The method of milking animals, including the pre-predile treatment of the udder, handles the nipple, facilitating the opening of the nipple sphincter. With the stroke Compression, the air from the pulsator (not shown) under pressure of 735.5 mm Hg and vacuum of 420 mm Hg in the cavity chamber 6 in the cavity covered by the annular chamber (under the nipple) enters the interlayer chamber of the teat cup. and the cavity above the annular chamber (on the sides of the tip, the nipple) is preserved. Differential pressure between Milking is possible at 42 pulses per minute (0.7 Hz), 60 pulses per minute (1 Hz) and 150 pulses per minute (2.5 Hz). Invention Formula The method of milking animals, including predorsing treatment of the udder, handing in 31 putting the teat cups on the nipples and removing the milk from them while simultaneously pulsing them with a pulsed pulse from the side of the nipple tube and the flexible wall of the annular chamber with the gaseous medium in it The longitudinal direction, characterized in that, in order to improve the protection of the tip of the nipple from the harmful effects of vacuum and stimulation of the lactation reflex, the surface of the tip of the nipple is applied at a frequency of 0.7-2.5 Hz at the pressure of the gaseous medium in the annular chamber 735.5- 760 mm Hg
