    [0004] Technical sector
    [0005]
    [0006] The present invention is related to the milking facilities that are used to automatically extract the milk from the producing animals, proposing a meter of the milk that is extracted in the milkings, with characteristics that improve the functionality of the facilities of application.
    [0007]
    [0008] State of the art
    [0009]
    [0010] An automatic milking installation includes vacuum operation mechanisms that extract the milk from the udders of the milked animals, to be sent to collection tanks, knowing the incorporation of complementary devices in said facilities to measure the amount of milk that is extracted in the milkings, in order to obtain information that allows to properly manage dairy farms.
    [0011]
    [0012] However, in the automatic measurement of milking milk, there may be changes in the actuator vacuum of the milking mechanisms, which affects the performance of the milking process and the health of the udders of the animals, which may be affected by the vacuum fluctuations.
    [0013]
    [0014] On the other hand, alterations of the quality of the milk that is milked can occur, since when passing through the measuring devices the milk can be denatured by the separation of its molecules when beaten, while the foam that is generated when the milk is beaten can alter the accuracy of the measurements, falsifying information on the amount of milk that is milked.
    [0015]
    [0016] Devices for measuring the amount of milk that is milked formed by a milk inlet chamber, a measuring chamber and a milk discharge outlet to a collection tank, with an arrangement of said spaces in consecutive overlapping are known forming a column, which determines that the device measurement results of a considerable vertical length, so that the course of the milk through the measuring device finds jumps of a certain height in which the milk is struck suffering a whipping effect with foam production, favoring that the alterations occur previously mentioned. See for example WO2011061868A1, or US3919975A. In addition, such devices of considerable vertical length can only be used in high-line milking facilities, where the device is located in an elevated position without space restrictions, but not in low-line milking facilities, where the device it is placed in a low position at ground level, requiring low-rise measuring devices in these installations.
    [0017]
    [0018] In order to avoid problems that affect the functionality of the milking facilities and the quality of the milking milk, it is therefore necessary to implement the milking facilities with meters of the amount of milk structured so as to avoid conditions conducive to the alteration of the vacuum and the milk shake.
    [0019]
    [0020] Object of the invention
    [0021]
    [0022] According to the invention, a milk meter for automatic milking facilities is proposed, with an embodiment that provides advantageous constructive and functional characteristics for the development of milking processes by means of application facilities.
    [0023]
    [0024] The milk meter object of the invention comprises a prechamber that is communicated with an inlet of the milk to be measured, a measuring chamber that is provided with milk level detecting means and a postchamber that is communicated with an evacuation outlet of the milk that goes to a collection container. The prechamber and the measuring chamber are located in a concentric arrangement, one inside the other, passing centrally through said concentric arrangement formed by the prechamber and the measuring chamber a double-acting valve that can move between two positions that establish alternative closure and communication between the measuring chamber and the pre-chamber, and between the measuring chamber and the post-chamber.
    [0025]
    [0026] The double-acting valve is axially hollow being open at its bottom towards the post chamber, while at the top it has holes that communicate with the pre-chamber, while the pre-chamber has, in turn, radial holes that communicate with the measuring chamber, so that a continuous passage between the outlet and the meter inlet is established through the double-acting valve, for the application of the milking drive vacuum, maintaining at the same time the same pressure in the prechamber and in the measuring chamber, which prevents alterations of the milk circulation and the vacuum flow.
    [0027]
    [0028] The communication between the prechamber and the measuring chamber is established by a narrow passage defined between a diametral narrowing of the prechamber and a diametral widening of the double acting valve, terminating said communication in the lower part of the measuring chamber, so that the circulation of the milk through the narrow passage undergoes a deceleration and the filling of the measuring chamber takes place from the bottom of the same upwards, circumstances that reduce the agitation of the milk and the formation of foam in the chamber of measurement, thus avoiding that the quality of the milk is altered and that the operating vacuum of the installation suffers fluctuations.
    [0029]
    [0030] In the pre-chamber, a spiral configuration surround screen is included, in which the milk that arrives through the milk meter inlet, so that said screen stops the incoming milk and directs it towards the central area where it is located the narrow passage that communicates with the measuring chamber, whereby the milk is led to the measuring chamber with a gentle treatment that avoids denaturation and facilitates measurement accuracy. The horizontal expansion of the milk in the area prior to said entrance step to the measuring chamber also contributes to the elimination of abruptness in the conduction of the milk to the measurement chamber, due to the width of the milk prechamber in that area.
    [0031]
    [0032] In the entrance passage to the measuring chamber, on the other hand, helical fins tangential to the direction of milk circulation are included, which revolutionize the flow of milk at the entrance to the measuring chamber, which prevents turbulence occurs, thereby improving the stability of the level of the milk in the measuring chamber and, thus, the accuracy of the measurement. To the stability of the milk level and, consequently, to the accuracy of the measurement, the entry of the milk into the measuring chamber through the lower part of said chamber also contributes.
    [0033]
    [0034] The concentric arrangement of the prechamber and the measuring chamber determines, on the other In part, a reduction in the height of the structural assembly of the milk meter, which allows a better adaptability of the application of the milk meter for milking facilities in places of limited space. Thus, this reduction in the height of the meter allows it to be used interchangeably in high-line milking facilities, where the meter is arranged in an elevated position, or low-line milking facilities, where the meter is disposed to the height of the ground
    [0035]
    [0036] Therefore, the milk meter object of the invention results in characteristics that make it advantageous for its function in milking facilities, acquiring its own life and preferential character with respect to known devices that are used for the same application.

    [0051]
    [0052] Detailed description of the invention
    [0053] The object of the invention relates to a milk meter for automatic milking facilities, comprising a prechamber (1) with which it communicates an input (2) of arrival of the milk to be measured from the milking of a producing animal, a chamber of measurement (3) in which electrodes (4) milk level detectors are arranged in said measuring chamber (3) and a post-chamber (5) that communicates with an outlet (6) for evacuating the milk to a tank of collection, axially going through the prechamber (1) and the measuring chamber (3) a double acting valve (7) that can move between a position (see figure 2) in which the prechamber (1) is in open communication with the measuring chamber (3), while the communication between measuring chamber (3) and the postcamera (5) is closed, and another position (see figure 4) in which the measuring chamber (3) it remains in open communication with the post-camera (5), while the communal nication between the prechamber (1) and the measuring chamber (3) is closed.
    [0054]
    [0055] The prechamber (1) and the measuring chamber (3) are located in a concentric arrangement, one inside the other, with communication between them by a narrow passage (8) that ends at the bottom of the measuring chamber (3 ) and which is defined between a diametral widening (9) of the double acting valve (7) and a diametral narrowing (10) of the prechamber (1).
    [0056]
    [0057] The double acting valve (7) is axially hollow, presenting a lower end open towards the post chamber (5), and an upper end having holes (11) that communicate with the prechamber (1), whereby inside A continuous communication between the outlet (6) and the inlet (2) is defined from the meter, whereby a drive vacuum of the milking mechanisms can be applied without interruption in the installation where the milk meter is arranged.
    [0058]
    [0059] The prechamber (1) in turn has radial holes (12) that communicate with the measuring chamber (3), which causes the prechamber (1) and the measuring chamber (3) to be maintained at the same pressure during the operation of the milk meter, preventing the application of the operating vacuum of the milking mechanisms from affecting the measurement conditions of the milk in the measuring chamber (3).
    [0060]
    [0061] In the prechamber (1) there is arranged around the double-acting valve (7) a spiral screen (13) of spiral configuration, in which the milk that arrives through the inlet (2), so that said enveloping screen (13) slightly slows the circulation of the milk flow entering the prechamber (1), and leads it towards the central area where the narrow passage (8) of communication with the measuring chamber (3). The enveloping screen (13) also prevents a part of the milk entering the prechamber (1) from passing directly to the measuring chamber (3) through the radial holes (12).
    [0062]
    [0063] The enveloping screen (13) allows the milk to be stopped at the entrance of the prechamber (1) and progressively directed towards the measuring chamber (3) avoiding the appearance of foam, however, an excessive deceleration of the milk flow can also give place to the appearance of foam, so that the diametral widening (9) of the double-acting valve (7) and the diametral narrowing (10) of the prechamber (1) that define the narrow passage (8) allows the possible foam that is generated stays in the prechamber (1) and does not pass into the measuring chamber (3), thus preventing it from affecting the measurement.
    [0064]
    [0065] On the other hand, helical fins (14) are included in the communication between the prechamber (1) and the measuring chamber (3), which (14) are positioned in a direction tangential to the milk circulation at the inlet to the measuring chamber (3), so that the milk is slightly revolutionized (accelerated) by the helical fins (14) when entering the measuring chamber (3), thus preventing turbulence. As indicated above, when passing the milk from the prechamber (1) to the measuring chamber (3) it can be excessively braked and foam may appear, so that the helical fins (14) slightly accelerate the revolution of the milk through the narrow passage (8) minimizing the appearance of the foam.
    [0066]
    [0067] In addition, the helical fins (14) act as a guiding element, so that they guide the double-acting valve (7) in its mobility between the two functional positions, for which the valve (7) is actuated by a actuator device (15),
    [0068]
    [0069] With all this, the process of operation of the milk meter in the activity of measuring the milk that arrives through the inlet (2) to be evacuated through the outlet (6), comprises two phases, in one of which the double valve effect (7) is closing the communication between the measuring chamber (3) and the post-chamber (5), while the communication between the pre-chamber (1) and the measuring chamber (3) is open, as shown in figures 2 and 3, whereby the milk that arrives at the entrance (2), affects the enveloping screen (13), which slows the circulation and directs the milk progressively towards the central area where the narrow passage (8) is located, through which the milk passes to the measuring chamber (3), where it enters with a revolution effect due to the helical fins (14), said measuring chamber (3) being filled until the level of the milk reaches the electrodes (4).
    [0070]
    [0071] In the measuring chamber (3), the provision of several electrodes (4) milk level detectors distributed at different heights is provided, which allows the quantity of milk measured in each measurement to be selected, since the operational phase The filling of the measuring chamber (3) ends when the milk level reaches the selected electrode (4), which activates the change of position of the double acting valve (7).
    [0072]
    [0073] The detection of the level of the milk by the corresponding electrode (4), is carried out in these conditions with precision, since the entrance of the milk in the measuring chamber (3) by the lower part makes the level rise stable and the entrance with revolution, due to the helical fins (14), prevents foaming.
    [0074]
    [0075] When the double-acting valve (7) changes position, it is positioned to leave the communication between the measuring chamber (3) and the post-chamber (5) open, while the communication between the pre-chamber (1) and the chamber measurement (3) is closed, as shown in Figure 4, then producing the second phase of the operating process, in which the milk contained in the measuring chamber (3) passes to the post chamber (5), to be evacuated through the outlet (6), while the milk that continues to arrive through the inlet (2) is stored in the prechamber (1), until the measuring chamber (3) is completely emptied, after which the valve of the valve changes again double effect (7), starting again the first phase of the functional process.
    [0076]
    [0077] In this way, the milk that reaches the milk meter during the first phase of the functional process, enters the prechamber (1) from above, being directed by the enveloping screen (13) towards the central area, where due to the width of the prechamber (1) the milk expands horizontally, to pass smoothly through the narrow passage (8) through which it reaches the bottom of the measuring chamber (3), whereby the level is achieved of the milk in said measuring chamber (3) rises steadily and without foaming, which also contributes to the entry of the milk with revolution in the measuring chamber (3), due to the helical fins (14 ), allowing with all this get a very precise milk measurement.
    [0078]
    [0079] And, on the other hand, in the second phase of the functional process, during the unloading of the milk and measurement of the measuring chamber (3), towards the post-chamber (5), the milk that continues to reach the milk meter is stored in the prechamber (1), whereby the milk meter can operate continuously in a complete milking process of a producing animal, making partial measurements of the milk that arrives through the inlet (2) from the milking process .
    [0080]
    [0081] The double-acting valve (7) incorporates at the open end towards the post-chamber (5) a gasket (16), with which it establishes in the first phase of the functional process of the milk meter a completely tight seal of the communication between the chamber of measurement (3) and the post-chamber (5), avoiding that by this communication milk leaks could occur that would falsify the result of the measurement of the milk that passes through the milk meter.
    [0082]
    [0083] The total height of the meter is between 150 and 300 mm and the diameter is between 100 and 150 mm, which allows its adaptation to high and low line milking facilities.
    [0084]
    [0085] The volumes of the measuring chamber (3) and the prechamber (1) are designed to measure accurately in increments of volume equivalent to 50 grams, at low and high flow rates of up to 13kg / min, occupying the smallest possible space and minimizing the milk turbulence (avoiding whipping and foaming).
    [0086]
    [0087] The volume housed in the measuring chamber (3) is measured by electrodes (4) that are located at different heights and are capable of measuring volumes equivalent to masses that follow the sequence 50, 100, 150, 200 and 250 grams. The variable sections, both of the double-acting valve (7) and the pre-chamber (1), are designed in a staggered manner with the aim of minimizing the volume contained in the pre-chamber (1) at the height of the electrodes (4) and maximize the content of the prechamber (1) above the electrodes (4) with the lowest possible height.
    [0088]
    [0089] The volume of the prechamber (1) is between 250,000 and 500,000 mm3 and the volume of the measuring chamber (3) is between 300,000 and 400,000 mm3. On the other hand, the post-chamber (5) is capable of housing an evacuation volume between 300,000 and 400,000 mm3.
    [0090]
    [0091] In order to achieve a filling of the measuring chamber (3) with sufficient speed and to allow high flow rates without great turbulence, the double-acting valve path (7) that allows the cameras to be connected and disconnected (1,3,5) is between 6 and 10 mm. The narrow passage (8) between the prechamber and the measuring chamber (3) has an area between 950 and 2500 mm2. This surface is obtained with a section at the exit of the chamber (1) between 50 and 80 mm in diameter and a section of the double-acting valve (7) at the height of the exit of the chamber (1) between 40 and 60 mm in diameter.
    [0092]
    [0093] To achieve a drainage of the measuring chamber (3) that allows high flow rates of up to 13kg / min, the effective section of the passage of the measuring chamber (3) to the post-chamber (5) must have an area between 950 and 2500 mm2 . In addition, the outlet (6) of the measuring chamber (3) must be between 50 and 80 mm in diameter to allow the passage of milk and emptying at high flow rates.
