RU # 2053654 C1, 01 J 7/00, 10.02.96.

These devices do not have sufficient reliability, difficult to operate and maintain.

The present invention is improving the efficiency of determining the suitability of cows to machine milking.

To achieve this effect in a milking apparatus, containing a two-chamber teat cups with the atmospheric valve manifold with milk tube, milking bucket malacologie, float level indicator, and an electronic unit for recording the time of milking, each teat Cup contains atmospheric valve for transporting milk, rigidly and hermetically mounted in the wall of the teat Cup, made in the form of a sleeve with a calibrated orifice and diaphragm. Each cylinder milking bucket contains molokoloco made in the form of truncated cones, facing a smaller base down and equipped with interchangeable nozzles. Each malacologica provided with two insulated from each other by the electrodes and the stator milk serving at the same time additional insulator between the electrodes. Each cylinder milking buckets equipped with a float device the m reception they received milk made in the form of float and gauge, and at the top of the line rigidly and hermetically installed valve, which during milking atmospheric pressure presses the guide sleeve milking buckets, and after milking float with a measuring range up to a height equal to the level of milk in the cylinder milking bucket.

The invention will be understood from the following description and the attached drawings.

Figure 1 shows the milking machine, General view; figure 2 is an atmospheric valve; figure 3 - malacologica with damper milk and replaceable nozzles.

The proposed milking machine (1) provided with teat cups 1 through monocottura pipe 2 connected to a milk tube 3 collector 4, the free ends of which in turn the hose 5 through the nozzles 6 are connected with malacologie 7 installed in each of the four measuring cylinders 8 milking buckets 9.

Each teat Cup 1 contains the atmospheric valve 10, through which pipe 11 is connected with its Podmoskovie camera 12. Annular chamber 13 of the teat Cup 1 by means of pipe 14 is connected to the variable vacuum chamber 15 of the collector 4 and then a pulsator (not shown).

Each cylinder 8 milking buckets 9 contains a float 16, which is connected with a measuring line 17 passing through the direction of the next sleeve 18, rigidly and hermetically fixed in the cover 19 of the milking bucket 9. The gauge contains 17 rigidly fixed vacuum valve 20. Cover 19 is milking buckets 9 contains the pipe 21 and fixed thereto an electronic device registration milking time 22.

The atmospheric valve 10 (figure 2) is designed as a sleeve 23 with a calibrated orifice 24 and the membrane 25. The atmospheric valve 10 through a pipe 11 is connected with Podmoskovie camera 12 teatcup 1 (figure 1). The teat Cup 1 through the pipe 2 is connected with the milk tube 3 collector 4, in turn they are connected with the milking pail through hose 5 connected to malacologie 7 through the nozzle 6. Malacologica 7 (figure 3) contains two identical, isolated from each electrode 26, the drain hole 27, overflow hole 28 and the damper milk 29, which also serves as an additional insulator between the electrodes 26. Moreover, the drain hole 27 provided with a set of interchangeable nozzles 30. For the flow of milk into the measuring cylinder 8 milking buckets 9 malacologica 7 have a drain hole 27 with a nozzle 30 (if the bandwidth of the nozzle exceeds the rate of milk) and overflow hole 28 (if the bandwidth of the nozzle does not exceed the speed of lactation of the animal).

Milking machine works as follows.

p> Malolotja tube 3 (Fig 1) collector 2 through the hose 5 is connected with the milking bucket 9, through which the milk pipe 21 connected to the milk line. The variable vacuum chamber 15 through the pulsator) connect a vacuum line (not shown) and open the clamp (not shown)mounted on the hose before the milk pipe 21. The vacuum through pipe 21 enters the cylinders 8 milking buckets 22 and then through molokoloco 7, the nozzle 6 through the milk hose 5 in Podmoskovye camera 12 teat Cup 1. Before putting the teat cups 1 on udder nipples in Podmoskovie chamber 12 and the inlet and the milk pipe 2 is set to almost atmospheric pressure.

After putting on the teat Cup 1 on the teats of the udder of cows in Podmoskovie the camera 12 is installed a vacuum, which is determined by the magnitude of the vacuum in the vacuum line. In the step of sucking the vacuum supplied to annular chamber teat Cup 1 from the variable vacuum chamber 15 due to the pressure difference between walls and Podmoskovie chamber 12 closes the calibrated aperture 24 of the membrane 25, the milking process will proceed as in conventional milking machine.

During the compression stroke of the diaphragm 25 of the atmospheric valve 10 (2) under the action of pressure difference will SAG, opening a calibrated orifice 24 of the sleeve 23, admits p is the resource center of air from the annular chamber in Podmoskovya during the compression stroke. Milk from Podmoskovie camera 12 carried by a portion of air from the annular chamber through the milk tube 3 and the hose 5 through the nozzle 6 enters molokoloco 7 (3), where, interacting with the stator milk 29 serving simultaneously insulator between the electrodes 26, flows under its own weight through the removable cap 30. If the flow of milk from Podmoskovie camera 12 in molokoloco 7 exceeds the throughput interchangeable nozzles 30, the milk flows through the overflow hole 28 molokoloco 7. Thus, the electrodes 26 are immersed in the milk and include electronic registration unit for milking time 22. From molokoloco 7 milk gets into the cylinder 8 milking buckets 9. After throughput of interchangeable nozzles 30 will exceed the share of milk output udder (50 or 100 ml/min), the electrodes 26 will open and on the electronic unit registration milking time 22 receives a signal, which will stop the timer. To increase the accuracy of determining the time of milking every malacologica 7 is equipped with a damper milk 29 reducing fluctuations in milk in malacologist. As in the cylinders 8 milking buckets 9 during the milking vacuum, the vacuum valve 20 is pressed by the atmospheric pressure against the sleeve 18 and thereby holds the float 16 is immersed in the milk.

Thus the process of milking during the compression stroke.

When completed the attachment of the milking close the clamp before the milk pipe 21 and remove the teat cups to the udder of the animal. The valve 20 does not hold the float which floats, simultaneously lifting the gauge 17, the height of lifting which determine the amount they received milk for each share of the udder.

The economic effect from the use of the proposed device can be obtained at the expense of productivity growth, more qualitative determination of the suitability of the animal to machine milking.
