Description

The vacuum spreads into the corrugated element 23, which contracts, the piston 19 moves down the glass, opens the opening 17, and the milk enters the interwall chamber 9, and from there into the milking bucket. In the rest tact corrugated

the element is aligned and the piston blocks the opening 17, eliminating the propagation of vacuum into the spout chamber. The nipple tube is leveled, providing a normal rest tact, 3 fcf, 2 ill.

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

The purpose of the invention is to increase the reliability of operation by providing a change in the mode of milking.

Figure 1 shows the milking machine; 2 is a section A-A in FIG. one.

The milking machine contains a pulsator 1 with a working chamber 2, a collector 3 with a milk chamber 4, milking cups 5, including each sleeve 6, a nipple tube 7 located in it, forming a spraying 8 and interwall 9 chambers, suckers 10, a milk branch pipe 11 with a milk tube 12, an air nozzle 13 with an air tube 14, a valve 15 for communicating between the interwall 9 and the self-supporting 8 chambers, made in the form of a rigid hollow body 16 with openings 17 and a lid 18 in which the piston 19 is installed, an additional nozzle 20 with the tube 21 rassechku which set the switch 22 mode milking.

Each milking cup 5 is provided with an elastic corrugated element 23 placed between the piston 19 and the lid 18, inside which a spring 24 is placed. In the case 16 an annular abutment 25 is made on its inner surface, and the holes 17 of the case 16 are angled to the axis of the cup 5, which provided with a latch 26 (not shown) mounted on the lid 18 and made in the form of a rod 27 with a handle 28 and a lock nut 29. The lid 18 is made removable.

The milking machine contains a milking bucket 30. Each milking cup 5 is equipped with an adjusting nut 31. The suction chamber chamber 9 of the cup 5 is connected with an air nozzle 13 by means of an additional tube 21.

The milking machine operates in two modes: in normal mode and in the nipple heating mode. In heating mode, the air tube 14 communicates with the working chamber 2 of the pulsator 1, and the milk tube 12 - with the milk chamber 4 of the collector 3, and in normal mode the air tube 14 communicates with the milk chamber 4 of the collector 3, and the milk tube 12 - with the working chamber 2 pulsator,

Milking machine works as follows.

When working in the nipple heating mode

The udder switch 22 is set to the Closed position, the air tube 14 is communicated with the working chamber 2 of the pulsator 1, and the milk tube 12 is connected with the milk chamber 4 of the collector 3. By means of the handle 28, the rod 27 is turned out of the cover and fixed in the lower position with the help of a lock nut 29.

In the vacuum cycle from the dairy chamber 4 of the collector 3, the milk tube 12 spreads in the interwall chamber 9 of the cup 5. At the same time, the vacuum from the working chamber 2 of the pulsator 1 passes through the air tube 14 in the corrugated element 23, which is reduced under the action of vacuum The piston 19 moves down the cup 5, opening the opening 17, since milk is above the piston and a vacuum extends below the piston 19.

Milk through the hole 17 enters the interwall chamber 9 and moves upward in it, giving away heat to the nipple tube 7, and through it the teats of the udder. Then the milk is transported through the milk pipe 11 and the pipe 20 into the chamber 4 of the collector 3 and then into the milking bucket 30.

In the rest stroke, the atmospheric pressure from the working chamber 2 of the pulsator 1 along the air tube 14 spreads in element 23. Under the action of vacuum in the podsoskoy chamber 8, the piston 19 moves upwards and element 23 is aligned. During its movement, the piston 19 blocks the opening 17. excluding the spread

vacuum in the spraying chamber 8. In this case the lactation and heating of the nipples cease. Nipple tube 7 is leveled, providing a normal rest tact. When the pulsator is switched, 1 cycle of operation is repeated.

When the machine is operating in normal mode, the switch 22 is set to the Open position, the air tube 14 is communicated with the milk chamber 4 of the collector 3, and the milk tube 12 - with the working chamber 2

pulsator 1.

The piston 19 is fixed in the upper position by means of the retainer 26, while the interwall chamber 9 and the underflow chamber 8 glasses 5 are disconnected, as the rod 27 holds the piston 19, which closes the opening 17. In this case, the milking machine operates in the usual two-stroke mode: and squeeze.

In the tact of sucking the nipple tube 7 due to the vacuum in the chambers 8 and 9, it is in a rectified state. The milk is sucked under the action of vacuum and through the nozzle 20, the tube 21 through the tube 14 is transported to the milk chamber 4 of the collector 3 and then to the milking bucket 30. The heating of the nipples does not occur.

In the compression stroke in chamber 9 of chamber 2 of the pulsator 1, atmospheric pressure propagates through pipe 12 and pipe 11. In the underflow chamber 8 from the chamber 4 of the collector 3, vacuum is distributed through the tube 14, the nozzle 20 and the tube 21. Due to the pressure difference nipple tube 7 compresses the nipple.

In the process of work, the nat

tube 7. To adjust its tension, it is enough to turn the nut 31 by 1-1.5 turns with one hand. As the tube 7 is worn out, its length is reduced by trimming, and by turning the nut 31, it is achieved its necessary tension.

The use of the proposed milking machine provides the best conditions for working on the dependence on external conditions by changing the appropriate milking regimen, reducing the incidence of mastitis in the cows, and the full yield.
