Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a milk claw for milking of a pipeline miller, which is capable of milking in a stable milking vacuum pressure state and prevents the milk flowing in the claw from backflushing. .

[0002]

2. Description of the Related Art As a conventional milk claw, a milk storage chamber is divided by the number of teat cups and is connected to milk lines such as teat cups so that milk is extracted from the outlet conduits installed in each chamber. And a bowl connected to the breast pump by a substantially circular connecting portion, and the cover has a substantially frustoconical shape and the lower large diameter portion is connected to the bowl. Each inlet nipple is connected to the upper side wall of the cover, each inlet nipple extends upwardly outward from the cover approximately tangentially to the side wall, and the incoming milk is directed downward and tangentially to the inner surface of the cover. After it is swung over the sloping inner wall of the cover, the velocity decreases due to the downward flow path of increasing flow diameter, with the outlet from the bowl below the inlet nipple. Receiving milk, breast pump, characterized in that there is a need to accelerate moving the milk upwards in order to flow back milk from the outlet nipple (JP 61-817
No. 40) is known.

However, in the case of the former milk claw of the related art, since the milk storage chamber is subdivided into four chambers, the milk storage chamber is full when the milk inflow amount is large compared to the milk discharge amount. Therefore, there is an inconvenience that continuous milking cannot be performed. In the case of the latter milk claw, there is a disadvantage that swirls are likely to occur in the milk storage chamber and the milk does not immediately flow out. Further, when the vortex is generated, the milk is agitated, which easily causes fat separation. Furthermore, when milk is vigorously flowing in from the milk nipple, it may flow back due to bounce and the like, in which case there is a risk of infection between other teats. Therefore, the present invention has been made in view of the above-mentioned drawbacks of the prior art, and it is difficult for a vortex to occur in the milk storage chamber,
Moreover, it aims at providing the milk claw in which backflushing does not easily occur.

[0004]

[Means for Solving the Problems] That is, the present invention is directed to a high vacuum which communicates with a milk reservoir and a milk outlet which communicate with four milk inlets defined by a partition plate having a pressure adjusting hole in the center of the claw chamber. A pressure chamber, a low vacuum pressure chamber isolated above the milk storage chamber via a diaphragm, and a pressure adjusting hole when the differential pressure between the milk storage chamber and the low vacuum pressure chamber connected to the diaphragm is above a predetermined level. This object is achieved by a milk claw of a milking machine in which a plurality of wave canceling plates are installed on the partition plate on the side of the milk reservoir from the side wall toward the central pressure adjusting hole. Further, it is desirable that the wave-eliminating plate is installed at a position intermediate between the milk inflow ports and at a position symmetrical with respect to the pressure adjusting hole. Further, in the milk claw in which the claw chamber of the second invention communicates with the upper four milk inlets and the lower milk outlet, the milk outlet is provided at the center of the bottom of the milk reservoir, and This object is achieved by a milk claw of a milking machine in which a plurality of wave-eliminating plates are installed at positions symmetrical with respect to the milk outlet.

[0005]

In the milk claw according to the present invention, milk expressed from the milk inlet through the tea cup unit flows into the milk storage chamber. Then, the milk accumulated in the milk accommodating chamber is introduced into the high vacuum pressure chamber through the pressure adjusting hole, and is fed from there through the milk outlet. When flowing into the high vacuum pressure chamber from the milk reservoir, a vortex is about to be generated around the pressure adjusting hole, but the wave-eliminating plate is installed on the partition plate in a point-symmetrical position around the pressure adjusting hole. Is canceled out of the relationship
No vortex is generated. In addition, the vigorous milk flowing in from the milk inflow port generally collides with the side wall and the like forming the chamber and bounces back, and tries to flow back to the other teat cups that are not under vacuum pressure. Since the baffle plate is installed on the partition plate, the baffle plate acts as a baffle plate for the milk spouting from the milk inlet, and thus acts so as not to bounce too much. In the second aspect of the invention, the action of the wave-eliminating plate installed at the bottom of the claw chamber prevents the generation of vortices and backflow as described above.

As shown in FIG. 3, the inside of the milk claw has a polygonal cross section, and the inside of the chamber is divided into a milk reservoir chamber 16 and a high vacuum pressure chamber 18 by a partition plate 14 having a pressure adjusting hole 12 in the center. The milk reservoir 16 communicates with the milk inlet 2, and the high vacuum chamber 18 communicates with the milk outlet 20. The milk discharge port 20 can be opened and closed by a hemispherical valve 22 so that dust or the like does not enter the claw when the milk is not milked. Reference numeral 24 is a rubber handle for locking the valve. Reference numeral 26 is a diaphragm for partitioning the low vacuum pressure chamber 28 above the milk storage chamber 16, and the diaphragm 26 is formed by the differential pressure between the vacuum pressure in the low vacuum pressure chamber 28 and the vacuum pressure in the milk storage chamber 16. By vertically moving the connected pressure adjusting rod 30, the pressure adjusting hole 12 is opened and closed to adjust the vacuum pressure in the milk reservoir chamber 16.
