Technical Field

[0001] The invention belongs to the technical field of animal husbandry breeding equipment, and in particular relates to a milk collection system and a collection method. Background Art

[0002] Mastitis is a common disease among dairy cows. Cows with mastitis not only produce less milk, but also reduce milk quality. The shelf life is shortened and some milk needs to be discarded, causing huge economic losses to the farm.

[0003] In view of this, it is necessary to detect cows with mastitis in time. When a cow is infected with mastitis, the sodium chloride content in the milk will increase and the conductivity of the milk will be higher. Therefore, it is possible to determine whether the cow has mastitis by measuring the conductivity of the milk.

[0004] At present, farms mostly use automatic milking equipment to milk multiple cows at the same time. The milk is collected through pipes into a collection device before being processed. Some cows with mastitis cannot be discovered in time, causing their milk to enter the collection device, which in turn affects the quality of other normal milk and poses a hidden danger to the farm's milk production. Summary of the invention

[0005] The present invention provides a milk collection system and a collection method to solve the current technical problem that the milk of cows with mastitis cannot be screened and diverted in a timely and effective manner, thereby preventing the diseased milk from mixing with normal milk and affecting the quality and safety of the milk, and improving the accuracy and automation of milk quality detection.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is: A milk collection system comprises a plurality of milking structures, wherein the output end of each of the milking structures is connected to a milk collecting pipe, and the output ends of the plurality of milk collecting pipes are connected to a milk collecting tank; The milking structure comprises a milking machine for milking cows and a transfer container for directly collecting milk, wherein the transfer container comprises a spiral milk collecting pipe, wherein the outlet end of the spiral milk collecting pipe is higher than the inlet end, and a first conductivity probe is installed on the bottom wall of the spiral milk collecting pipe near the top; The end of the spiral milk collecting pipe is connected to a first outlet pipe and a second outlet pipe, the first outlet pipe is communicated with the milk collecting tank, the outlet end of the second outlet pipe is connected to a recovery tank, and the inlet ends of the first outlet pipe and the second outlet pipe are both provided with a first opening and closing valve.

[0007] Furthermore, a second conductivity probe is installed on the bottom wall of the milk collecting pipe close to the milk outlet port.

[0008] Furthermore, a partition is provided in the transfer container, and the partition divides the transfer container into a temporary milk storage space and a second storage space. The spiral milk collection pipe is arranged in the second storage space. The partition is provided with a connecting port near the bottom area, and the inlet end of the spiral milk collection pipe is connected to the connecting port.

[0009] Furthermore, a support frame for supporting the spiral milk collecting pipe is arranged in the second storage space, a liquid cooling pipe is also arranged on the support frame, and a blasting device is arranged inside the support frame.

[0010] Furthermore, a second on-off valve is provided on the milk collecting pipeline, a branch pipe is provided in communication with the upstream end of the second on-off valve on the milk collecting pipeline, and a third on-off valve is installed on the branch pipe.

[0011] Furthermore, the rear section of the milk collecting pipe is spirally fixed outside the milk collecting tank, and the initial contact point between the milk collecting pipe and the milk collecting tank is lower than the milk discharge point of the milk collecting pipe.

[0012] Furthermore, the spiral milk collecting pipe is provided with a widening section near the communicating port, the inner diameter of the widening section gradually increases towards the communicating port; and a filter is provided at the communicating port.

[0013] Furthermore, a vacuum negative pressure environment is formed in the milk collecting tank, and a fourth opening and closing valve is provided at the port where each milk collecting pipe communicates with the milk collecting tank.

[0014] Furthermore, a milk discharge pipe is connected to the bottom of the temporary milk storage space.

[0015] In another aspect, the present application provides a milk collection method, comprising the following steps: S1, closing the inlet end of the spiral milk collecting pipe, using a milking machine to milk, and collecting the squeezed milk into a temporary milk storage space until the liquid level of the milk collected in the temporary milk storage space is higher than the spiral milk collecting pipe; S2, connecting the spiral milk collecting pipe and the temporary milk storage space, so that the milk flows along the spiral milk collecting pipe to the first conductivity probe; S3, using the first conductivity probe to measure the conductivity of the milk, if the conductivity value of the milk meets the standard, the milk flows out through the first outlet pipe; if the conductivity value of the milk does not meet the standard, the milk flows out through the second outlet pipe; S4. The milk flowing out of the first outlet pipe flows along the milk collecting pipe. The conductivity of the milk is measured again by a second conductivity probe at the end of the milk collecting pipe. If the test value meets the standard, the milk in the milk collecting pipe is collected in a milk collecting tank; if the test value does not meet the standard, the outlet end of the milk collecting pipe is closed.

[0021] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided 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.

[0022] like Figure 1 and Figure 2 As shown, a milk collection system includes a plurality of milking structures 1, wherein the milking structure 1 includes a milking machine 11 and a transfer container 12. The milking machine 11 is used to realize automatic milking of a cow, which is a prior art and will not be described in detail here. The transfer container 12 is arranged at the outlet end of the milking machine 11, and a partition plate 15 is arranged in the transfer container 12. The partition plate 15 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 connected to the milk outlet end of the milking machine 11, and a spiral milk collecting pipe 121 is arranged in the second storage space 17. The output end of the spiral milk collecting pipe 121 is connected to a milk collecting pipe 2, and the output end of the milk collecting pipe 2 is connected to a milk collecting tank 3, and multiple milk collecting pipes 2 are all connected to the milk collecting tank 3.

[0023] The milking structure 1 is used to realize automatic milking of each cow. The squeezed milk is first collected in the temporary milk storage space 16, then enters the spiral milk collecting pipe 121, flows into the milk collecting pipe 2 along the spiral milk collecting pipe 121, and finally is collected in the milk collecting tank 3, thereby realizing the collection of the entire process of milk.

[0024] Among them, a first conductivity probe 4 is installed on the bottom wall of the spiral milk collecting pipe 121 near the top, and a second conductivity probe is arranged on the bottom wall of the milk collecting pipe 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 cow, and then the conductivity of the milk can be detected to accurately detect whether the cow suffers from mastitis.

[0025] A connecting port 151 is provided near the bottom of the partition plate 15, and the inlet end of the spiral milk collecting pipe 121 is connected to the connecting port 151; and a widening section 122 is provided near the connecting port 151 of the spiral milk collecting pipe 121, and the inner diameter of the widening section 122 gradually increases toward the connecting port 151; and a filter screen 123 is provided at the connecting port 151. First, the milk squeezed out of the milking structure 1 is collected in the temporary milk storage space 16. Since there is foam when milk is just squeezed out and the temperature is high, these two factors will have a great impact on the detection of milk conductivity, thereby affecting the accuracy of milk conductivity detection. Therefore, an on-off switch is set at the connecting port 151. When the milking structure 1 is working, the connecting port 151 is closed and milk is collected in the temporary milk storage space 16. When the milk liquid level is higher than the connecting port 151 or even forms a higher liquid level, the connecting port 151 is opened. At this time, the milking structure 1 can work while the milk in the temporary milk storage space 16 enters the spiral milk collecting pipe 121 through the connecting port 151.

[0026] The filter 123 can reduce the amount of milk foam entering the spiral milk collecting pipe 121, but the filter 123 will reduce the flow rate of milk. Therefore, the widening section 122 is provided at the end of the spiral milk collecting pipe 121 to ensure the flow rate of milk. It should be noted that the inlet end of the spiral milk collecting pipe 121 is lower than the outlet end of the spiral milk collecting pipe 121. The milk is collected in the temporary milk storage space 16 until the liquid level of the milk is higher than the outlet end of the spiral milk collecting pipe 121, and then the connecting port 151 is opened; 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 pipe 121 will be more uniform and slow, so that the milk can flow through the first conductivity probe 4 more stably to improve the accuracy of the detection of the first conductivity probe 4.

[0027] Furthermore, a milk discharge pipe 161 is connected to the bottom of the temporary milk storage space 16. When the milk collection system of the present application is used to collect milk, milk is still deposited at the bottom of the temporary milk storage space 16. The milk discharge pipe 161 can be used to drain the remaining milk in the temporary milk storage space 16 to reduce milk waste.

[0028] A support frame 6 is installed in the second storage space 17, and the support frame 6 can support the spiral milk collecting pipe 121; a liquid cooling pipe 7 is also provided on the support frame 6, and cold water for cooling flows in the liquid cooling pipe 7, and a blasting device 8 is also provided in the middle of the support frame 6. Usually, the temperature of milk when it is squeezed out of the cow is about 37°C, and a higher temperature will increase the conductivity of the milk, thereby affecting the detection result; maintaining the temperature of the milk in the range of 20°C-25°C can more accurately detect the conductivity index, so the second storage space 17 is cooled by the blasting device 8 and the liquid cooling pipe 7, thereby reducing the temperature of the milk in the spiral milk collecting pipe 121 and improving the conductivity detection accuracy.

[0029] The outlet end of the spiral milk collecting pipe 121 is connected to the first outlet pipe 13 and the second outlet pipe 14, the first outlet pipe 13 is in communication with the milk collecting pipe 2, and the outlet end of the second outlet pipe 14 is connected to the recovery tank 5; in addition, the first outlet pipe 13 and the inlet end of the second outlet pipe 14 are both provided with a first opening and closing valve 131. After the milk flows through the first conductivity probe 4, the conductivity detection is realized. If the detection result is qualified, the first opening and closing valve 131 on the first outlet pipe 13 is opened, and the milk flows into the milk collecting pipe 2; if the detection result is unqualified, the first opening and closing valve 131 on the second outlet pipe 14 is opened, and the milk is collected in the recovery tank 5. At this time, the staff can perform disease screening and treatment on the cows corresponding to the milking structure 1.

[0030] Furthermore, the milk collecting pipe 2 is provided with a second opening and closing valve 21, which can block the milk collecting pipe 2; in addition, the milk collecting pipe 2 is connected to a branch pipe 22 at the upstream end of the second opening and closing valve 21, and a third opening and closing 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 during the process, the second opening and closing valve 21 is immediately closed while the first opening and closing valve 131 on the first outlet pipe 13 is closed, and the third opening and closing valve 23 on the branch pipe 22 is opened to discharge the milk in the milk collecting pipe 2 for further detection. At the same time, the milk collecting pipe 2 is cleaned. Since other milk collecting pipes 2 need to work normally, the second opening and closing valve 21 is closed, and the third opening and closing valve 23 is opened, so that the cleaning liquid can be discharged along the milk collecting pipe 2 and the branch pipe 22, and does not flow into the milk collecting tank 3, so as to reduce the impact on the normal operation of other milking structures 1.

[0031] The rear section of the milk collecting pipe 2 is threadedly fixed outside the milk collecting tank 3, and 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. At the same time, a vacuum negative pressure environment is formed in the milk collecting tank 3, thereby providing power for the milk to be discharged 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 outlet end. The second conductivity probe is used to realize the second conductivity detection of milk. The milk flows along the milk collecting pipe 2 around the milk collecting tank 3 in a spiral, and the flow will be more uniform. At the same time, the milk flows upward, and the flow rate will be reduced, so that the detection result of the second conductivity is more accurate. The conductivity of milk is detected again by the second conductivity, which can further eliminate the influence of other interference factors on the conductivity detection of milk and improve the accuracy.

[0032] After the detection result of the second conductivity probe is qualified, the milk is discharged into the milk collecting tank 3 from the side wall of the milk collecting tank 3, and the collection of milk is completed; a fourth opening and closing valve is provided at the port where each milk collecting pipe 2 is connected to the milk collecting tank 3. If the detection result of the second conductivity probe is unqualified, the fourth opening and closing valve is closed, the first opening and closing valve 131 on the corresponding first outlet pipe 13 is closed, and the third opening and closing valve 23 is opened at the same time, and the milk in the milk collecting pipe 2 is discharged along the branch pipe 22 for further quality inspection.

[0033] The present application also provides a milk collection method, which uses the above-mentioned milk collection system to collect milk, and specifically includes the following steps: S1, closing the inlet end of the spiral milk collecting pipe 121, using the milking machine 11 to milk, and collecting the milked milk into the temporary milk storage space 16 until the liquid level of the milk collected in the temporary milk storage space 16 is higher than the spiral milk collecting pipe 121; S2, connecting the spiral milk collecting pipe 121 and the temporary milk storage space 16, so that the milk flows along the spiral milk collecting pipe 121 to the first conductivity probe 4; S3, using the first conductivity probe 4 to measure the conductivity of the milk, 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; S4. The milk flowing out of the first outlet pipe 13 flows along the milk collecting pipe 2. The conductivity of the milk is measured again by a second conductivity probe at the end of the milk collecting pipe 2. If the detected value meets the standard, the milk in the milk collecting pipe 2 is collected in the milk collecting tank 3; if the detected value does not meet the standard, the outlet end of the milk collecting pipe 2 is closed.

[0034] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
