DETAILED DESCRIPTION

[0032] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the accompanying drawings. The embodiments of the present application are shown in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0033] As shown in Figure 1 and Figure 2 , a milk collection system comprises a plurality of milking structures 1, each milking structure 1 comprising a milker 11 and a transfer container 12. The milker 11 is used to realize automatic milking of a dairy cow, and the prior art will not be described in detail here. The transfer container 12 is arranged at the outlet end of the milker 11. The transfer container 12 is provided with a partition plate 15, which divides the space in the transfer container 12 into a temporary milk storage space 16 and a second storage space 17. The temporary milk storage space 16 is in communication with the milk discharge end of the milker 11, and the second storage space 17 is provided with a spiral milk collection pipeline 121.

[0034] The milking structure 1 is used to realize automatic milking of each dairy cow. The milk is first collected into the temporary milk storage space 16, then flows into the spiral milk collection pipeline 121, and then flows into the milk collection pipeline 2, and finally is collected into the milk collection tank 3, thereby realizing the collection of the whole process of the milk.

[0035] The first conductivity probe 4 is arranged on the bottom wall of the spiral milk collection pipeline 121 near the top, and the second conductivity probe is arranged on the bottom wall of the milk collection pipeline 2 near the outlet end. The first conductivity probe 4 and the second conductivity probe are used to realize two conductivity measurements of the milk produced by each dairy cow, and then the conductivity of the milk is detected to accurately detect whether the dairy cow has mastitis.

[0036] The partition plate 15 is provided with a communication port 151 near the bottom area, the inlet end of the spiral milk collecting pipeline 121 communicates with the communication port 151, and the spiral milk collecting pipeline 121 is provided with a widened section 122 near the communication port 151, the inner diameter of the widened section 122 gradually increases in the direction of the communication port 151, and a filter screen 123 is arranged at the communication port 151. First, the milk squeezed out by the milking structure 1 is collected into the temporary milk storage space 16. Because the milk just squeezed out has foam and is high in temperature, these two factors will greatly affect the detection of the electrical conductivity of the milk, and then affect the accuracy of the detection of the electrical conductivity of the milk, therefore, the on-off switch is arranged at the communication port 151, when the milking structure 1 works, the communication port 151 is closed, the milk is collected in the temporary milk storage space 16, when the liquid level of the milk is higher than the communication port 151 or even forms a higher liquid level, the communication port 151 is opened, at this time, the milking structure 1 works, and the milk in the temporary milk storage space 16 enters the spiral milk collecting pipeline 121 through the communication port 151 at the same time.

[0037] The filter screen 123 can reduce the amount of foam of the milk entering the spiral milk collecting pipeline 121, but the arrangement of the filter screen 123 reduces the flow of the milk, therefore, the widened section 122 is arranged at the end of the spiral milk collecting pipeline 121 to ensure the flow of the milk. It should be noted that the inlet end of the spiral milk collecting pipeline 121 is lower than the outlet end of the spiral milk collecting pipeline 121, the milk is collected in the temporary milk storage space 16, and then the communication port 151 is opened when the liquid level of the milk is higher than the outlet end of the spiral milk collecting pipeline 121; under the action of the hydraulic pressure difference, the milk flows upward, but the flow rate of the milk flowing along the spiral milk collecting pipeline 121 is more uniform and slow, and then the milk can more stably flow through the first electrical conductivity probe 4, so as to improve the accuracy of the detection of the first electrical conductivity probe 4.

[0038] Further, the bottom of the temporary milk storage space 16 is connected with a milk discharge pipeline 161, when the milking of the milk collecting system ends, the bottom of the temporary milk storage space 16 still deposits milk, the remaining milk in the temporary milk storage space 16 can be discharged by the milk discharge pipeline 161, so as to reduce the waste of the milk.

[0039] The second storage space 17 is provided with a support frame 6, the support frame 6 can support the spiral milk collecting pipeline 121, the support frame 6 is also provided with a liquid cooling pipeline 7, cooling water flows in the liquid cooling pipeline 7, and the support frame 6 is also provided with a blowing equipment 8. The temperature of the milk squeezed out from the cow is about 37℃, and the high temperature will increase the electrical conductivity of the milk, and then affect the detection result, the milk is maintained in the temperature interval of 20-25℃, so as to more accurately detect the electrical conductivity index, therefore, the blowing equipment 8 and the liquid cooling pipeline 7 realize the cooling of the second storage space 17, so as to reduce the temperature of the milk in the spiral milk collecting pipeline 121, and improve the electrical conductivity detection accuracy.

[0040] The spiral milk collection pipe 121 has a first outlet pipe 13 and a second outlet pipe 14 connected to its outlet end. The first outlet pipe 13 is connected to the milk collection pipe 2, and the outlet end of the second outlet pipe 14 is connected to a recovery tank 5. Additionally, a first on / off valve 131 is installed at the inlet end of both the first outlet pipe 13 and the second outlet pipe 14. When milk flows through the first conductivity probe 4, conductivity is detected. If the test result is satisfactory, the first on / off valve 131 on the first outlet pipe 13 opens, and the milk flows into the milk collection pipe 2. If the test result is unsatisfactory, the first on / off valve 131 on the second outlet pipe 14 opens, and the milk is collected into the recovery tank 5. At this time, workers can perform disease screening and treatment on the cows corresponding to the milking structure 1.

[0041] Furthermore, a second on / off valve 21 is installed on the milk collection pipe 2, which can block the milk collection pipe 2. In addition, a branch pipe 22 is connected to the upstream end of the second on / off valve 21, and a third on / off valve 23 is installed on the branch pipe 22. Since the milk is flowing during the collection process, when the first conductivity probe 4 detects the conductivity of the flowing milk, if the conductivity of the milk is found to be unqualified, the first on / off valve 131 on the first outlet pipe 13 is closed, the second on / off valve 21 is immediately closed, and the third on / off valve 23 on the branch pipe 22 is opened to discharge the milk in the milk collection pipe 2 for further testing. At the same time, the milk collection pipe 2 is cleaned. Since other milk collection pipes 2 need to work normally, the second on / off valve 21 is closed and the third on / off valve 23 is opened, so that the cleaning fluid can be discharged along the milk collection pipe 2 and the branch pipe 22 without flowing into the milk collection tank 3, thereby reducing the impact on the normal operation of other milking structures 1.

[0042] The rear section of the milk collecting pipe 2 is threaded and fixed to the outside of the milk collecting tank 3. The initial contact point between the milk collecting pipe 2 and the milk collecting tank 3 is lower than the milk discharge point of the milk collecting pipe 2. Simultaneously, a vacuum negative pressure environment is created inside the milk collecting tank 3, providing the power for milk to flow from the milk collecting pipe 2 into the milk collecting tank 3. A second conductivity probe is installed on the bottom wall of the milk collecting pipe 2 near the milk discharge end. This second conductivity probe is used to perform a second conductivity test on the milk. As the milk flows spirally along the milk collecting pipe 2 around the milk collecting tank 3, the flow becomes more uniform. Simultaneously, the upward flow of the milk reduces the flow velocity, making the second conductivity test result more accurate. This second conductivity test further eliminates the influence of other interfering factors on the milk conductivity test, improving accuracy.

[0043] After the second conductivity probe detects that the milk is qualified, the milk is discharged from the side wall of the milk collection tank 3 into the milk collection tank 3, completing the milk collection. A fourth on / off valve is installed at the port where each milk collection pipe 2 connects to the milk collection tank 3. If the detection structure of the second conductivity probe is unqualified, the fourth on / off valve is closed, the first on / off valve 131 on the corresponding first outlet pipe 13 is closed, and the third on / off valve 23 is opened. The milk in the milk collection pipe 2 is discharged along the branch pipe 22 for further quality testing.

[0044] This application also provides a milk collection method, which uses the above-mentioned milk collection system to collect milk, specifically including the following steps:

[0045] S1. Close the inlet end of the spiral milk collection pipe 121, use the milking machine 11 to milk, and collect the milk into the temporary milk storage space 16 until the milk level in the temporary milk storage space 16 is higher than the spiral milk collection pipe 121.

[0046] S2, connect the spiral milk collection pipe 121 and the temporary milk storage space 16, so that the milk flows along the spiral milk collection pipe 121 to the first conductivity probe 4;

[0047] S3. Measure the conductivity of the milk using the first conductivity probe 4. If the conductivity value of the milk meets the standard, the milk flows out through the first outlet pipe 13; if the conductivity value of the milk does not meet the standard, the milk flows out through the second outlet pipe 14.

[0048] S4. The milk flowing out of the first outlet pipe 13 flows along the milk collection pipe 2. At the end of the milk collection pipe 2, the conductivity of the milk is measured again using the second conductivity probe. If the detection value meets the standard, the milk in the milk collection pipe 2 is collected into the milk collection tank 3; if the detection value does not meet the standard, the outlet end of the milk collection pipe 2 is closed.

[0049] The above description is only a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
