Abstract

This invention relates to agriculture. The purpose of the invention is to increase the efficiency of milking. The milking machine contains teat cups 1. having a sleeve 2, a nipple tube 5. Diametrically bellows 8 and 9 are installed in the interwall chamber. Above the bellows outside the nipple tube there is a stop with a slot that communicates with the milk hose. The bellows cavities are in communication with a variable vacuum source. When a variable pressure is applied to the cavity of the sylphon 8, it contracts and pulls the nipple tube behind it, and the nipple contracts against the stop, while the bellows 9 expands. When applying alternating pressure with the syringe 9, the nipple on the other side is compressed. 1 hp ff, 4 ill.

Description

Fig.Z

The invention relates to agriculture, in particular to machine milking of cows,

The purpose of the invention is to increase the efficiency of milking.

1 shows a schematic of a milking machine, a rest stroke; figure 2 - section aa in figure 1; on fig.Z - section bb in figure 1; 4 shows the milking machine, during compression on the right side.

The milking machine contains milking cups 1 having a sleeve 2, on the inner surface of which circumferentially formed protrusions 3, on which a cylindrical support 4 rests, a nipple tube 5 with a suction cup 6, having an annular recess 7 in which elastic deformers of the teat are installed with their blind ends, made in the form of bellows 8 and 9, fixed in the connector 10 of the sleeve 2.

The rest 4 has a slot 11 connected to the milk hose 12. The cavity of the nipple tube 5 communicates with the spouting chamber 13, and a removable plug 14 is installed in the lower part of the sleeve 2, which is removed during the warm season, the spouting chamber 13 communicates with the milk hose 12.

The pulsator collector 15 of the milking machine includes a body 16, a cover 17, taps 18 and 19 of the tact adjustment, partitions 20 and 21, membranes 22 and 23, valves 24 and 25. The pulsator collector has alternating pressure chambers 26 and 27, a milk chamber 28 communicated with the milk line, chambers 29 and 30 of atmospheric pressure, working chambers 31 and 32.

The variable pressure chambers 26 and 27 are geo-connected to the chambers 31 and 32, and the latter, via air hoses 33 and 34, with elastic corrugated tubes 8 and 9.

Milking machine works as follows.

In the rest stroke (Fig. 1), the vacuum through the main milk line continuously spreads in the chamber 28 of the milking unit's pulsator and then through the milk hose 12 into the suction chamber 13 of the teat cup 1. Under the action of the vacuum, the milk is transported from the bottom of the nipple tube 5 along its entire length and through the slot 11 and the milk hose 12 into chamber 28 and further into the milk line, while heating the nipple from its tip to the base through the wall of the nipple tube 5. At this time, valves 24 and 25 are closed, and the atmospheric pressure from ka5

measures 29 and 30 spread into working chambers 31 and 32 of variable pressure. And then through air hoses 33 and 34 - into the cavity of bellows 8 and 9. At the same time, the teat

the tube does not work on the nipple. There is a rest tact with simultaneous heating of the udder nipples.

In the compression stroke on the left side of the teat cup (Fig. 4) the vacuum from the chamber 28

through the open valve 25 extends into the working chamber 32 of alternating pressure and through the air hose 34 into the cavity of the bellows 8, which is compressed, draws the nipple tube 5 through the recess 7, and the nipple compresses against the stop 4, while the bellows 9 is expanded, so how at that time atmospheric pressure spreads in its cavity.

 At the same time, the vacuum from chamber 27 propagates into chamber 32 through a pipeline with a valve 19 for adjusting the tact of the apparatus.

In the compression stroke on the right side of the tempered glass 1, the vacuum from the chamber 28 spreads through the open valve 24 into the working chamber 31 of the variable pressure, then through the air hose 33- into the cavity of the bellows 9, which, compressing, draws

0 a nipple tube 5 to the right.

The nipple tube 5 is compressed around the stop 4, while the nipple is compressed and the milk enters the podososkovaya chamber 13 of the teat cup 1.

5 The bellows 8 is pulled out, as in its

The cavity at this time is subject to atmospheric pressure.

Adjusting the ratio of the duration of the compression and rest cycles takes place with the adjusting valves 18 and 19 in such a way that the compression and rest cycles alternate: two compression cycles and one rest cycle, as during the operation of a three-stroke milking machine.
