[0029] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] In the related art, if operators encounter a large-diameter or long pipe, manual tightening not only increases the workload, but also makes it difficult to connect the long pipe, which can easily lead to milk leakage.

[0031] In order to provide a stable connection and convenient docking method during the milk collection process, and ensure the efficiency and safety of the milk collection process, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the milk collection interface device of the embodiment of the utility model comprises: a milk collection pipe 2 suitable for connecting to the milk inlet of the milk collection vehicle and an output pipe 1 suitable for connecting to the milk outlet of the milk supply line.

[0032] The output tube 1 includes a first tube body 11 and a first connecting disk 12 sleeved on the outer wall of the first tube body 11. The milk collecting tube 2 includes a second tube body 21 and a connecting part. The connecting part includes a second connecting disk 22 and a connecting sleeve 23. The second connecting disk 22 is sleeved on the outer wall of the end of the second tube body 21. The connecting sleeve 23 is arranged on the side of the second connecting disk 22. The connecting sleeve 23 is provided with an accommodating space 24. The first tube body 11 is arranged in the accommodating space 24 and docked with the second tube body 21. The first connecting disk 12 is provided with an abutting surface. The end surface of the connecting sleeve 23 is magnetically connected to the abutting surface.

[0033] Specifically, the output tube 1 mainly includes a first tube body 11 and a first connection plate 12 sleeved on the outer wall of the first tube body 11. The first tube body 11 is the main milk delivery channel, and its design should take into account the fluidity and cleanliness of the milk to ensure that the milk will not be contaminated during the delivery process. The first connection plate 12 is provided to stably connect with the milk receiving tube 2.

[0034] Secondly, the milk collecting tube 2 includes a second tube body 21 and a connecting portion. The second tube body 21 also serves as a milk delivery channel, and its design standard is similar to that of the first tube body 11. The connecting portion is an important connecting structure, including a second connecting disk 22 and a connecting sleeve 23. The second connecting disk 22 is sleeved on the outer wall of the end of the second tube body 21 to fix and enhance the structural stability. The connecting sleeve 23 is arranged on the side of the second connecting disk 22, and a containing space 24 is provided inside it for accommodating the first tube body 11 to achieve docking between the two.

[0035] During the docking process, the first tube body 11 is inserted into the accommodating space 24 of the connecting sleeve 23 and docked with the second tube body 21. At this time, the abutting surface of the first connecting plate 12 is tightly fitted with the end surface of the connecting sleeve 23. In order to ensure the stability and sealing of the connection, a magnetic connection is adopted between the end surface of the connecting sleeve 23 and the abutting surface. This magnetic connection is not only convenient for operation, but also ensures that there will be no milk leakage during the docking process.

[0036] In addition, in order to ensure smooth and hygienic milk delivery, all components of the milk receiving interface device of the embodiment of the utility model are made of food-grade materials, and the surface is smooth without dead corners, which is easy to clean and disinfect. At the same time, the connection between the components also adopts a sealing design to avoid contamination and waste of milk during the delivery process.

[0037] In practical applications, the milk collection interface device of the embodiment of the utility model can be widely used in various links of dairy product production. For example, in the process of collecting milk in a dairy farm, the device can be used to collect milk from the cows and transport it to the storage device; in the process of processing dairy products, the device can also be used to transport milk from the storage device to the processing device. Since the device has the advantages of simple operation, stable connection, good sealing, etc., it can greatly improve the efficiency and safety of the milk collection process and reduce production costs.

[0038] The milk collecting interface device of the embodiment of the utility model realizes stable connection and convenient docking during the milk collecting process, and has broad application prospects and practical value.

[0039] In an optional embodiment, one of the first connecting disk 12 and the connecting sleeve 23 is provided with an electromagnet, and the other is provided with a magnetic attraction member that attracts the electromagnet when powered on.

[0040] Specifically, the electromagnet can be set on the first connection disk 12, and the magnetic attraction piece is fixed on the connection sleeve 23. When docking is required, the first tube body 11 is first inserted into the accommodating space 24 of the connection sleeve 23, so that the end faces of the first connection disk 12 and the connection sleeve 23 are close. Then, the electromagnet is energized, and the electromagnet generates magnetic force to attract the magnetic attraction piece, so that the first connection disk 12 and the connection sleeve 23 are tightly fitted. This magnetic connection method is not only convenient and fast, but also has a firm connection and is not easy to fall off.

[0041] In addition, when the connection is no longer needed, the power supply of the electromagnet only needs to be disconnected, the magnetic force disappears, and the first connection plate 12 and the connection sleeve 23 can be easily separated. This design greatly simplifies the disassembly process of the milk receiving interface device and improves work efficiency.

[0042] In an optional embodiment, an electromagnet is provided on the outer wall of the connecting sleeve 23, and a magnetic attraction member is provided on the abutting surface.

[0043] When milk needs to be collected, the first tube body 11 of the output tube 1 is inserted into the accommodating space 24 of the connecting sleeve 23 of the milk collecting tube 2, so that the abutting surface of the first connecting disk 12 is close to the end surface of the connecting sleeve 23. Then, the electromagnet on the outer wall of the connecting sleeve 23 is energized, and the electromagnet generates magnetic force to attract the magnetic suction piece on the abutting surface, so that the first connecting disk 12 and the connecting sleeve 23 are closely fitted. At this time, the first tube body 11 and the second tube body 21 are connected, and the milk can flow smoothly from the output tube 1 into the milk collecting tube 2.

[0044] It should be noted that the magnetic connection method is not only easy to operate, but also has a firm and reliable connection. At the same time, due to the design of the electromagnet and the magnetic attraction, the connecting sleeve 23 and the first connecting plate 12 can be easily separated after the power is disconnected, which is convenient for subsequent cleaning and maintenance.

[0045] In order to further enhance the connection stability and safety between the output tube 1 and the milk receiving tube 2, in an optional embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the milk receiving interface device also includes a connector 3, the first connecting plate 12 is further provided with a mounting surface opposite to the abutting surface, the first end of the connector 3 is provided on a side of the second connecting plate 22 away from the connecting sleeve 23, and the second end of the connector 3 is detachably provided on the mounting surface.

[0046] This design enables the connector 3 to reinforce the output tube 1 and the milk receiving tube 2 from the docking direction after the two are docked, thereby improving the overall connection stability. At the same time, since the connector 3 and the mounting surface of the first connection plate 12 are detachably connected, the connector 3 can be easily removed when disassembly or maintenance is required, which is convenient for subsequent cleaning and maintenance.

[0047] In the specific implementation process, when milk needs to be collected, the first tube body 11 of the output tube 1 is first inserted into the accommodating space 24 of the connecting sleeve 23 of the milk collecting tube 2, so that the abutting surface of the first connecting disk 12 is closely fitted with the end surface of the connecting sleeve 23. Then, the first end of the connecting member 3 is fixed on the second connecting disk 22, and the second end of the connecting member 3 is connected to the mounting surface of the first connecting disk 12, thereby completing the connection of the entire milk collecting interface device.

[0048] In an optional embodiment, if Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the connecting member 3 includes a first connecting portion 33, a horizontal portion 32 bent and extended from the first connecting portion 33, and a second connecting portion 31 bent and extended from the horizontal portion 32. The first connecting portion 33 is arranged on the side of the second connecting plate 22 away from the connecting sleeve 23, and the second connecting portion 31 is detachably arranged on the installation surface.

[0049] The connecting member 3 is specially designed as a component with multiple bent parts to provide a more stable and easy-to-operate connection method. The connecting member 3 includes a first connecting portion 33, a horizontal portion 32 bent and extended from the first connecting portion 33, and a second connecting portion 31 bent and extended from the horizontal portion 32.

[0050] The first connection part 33 is arranged on the side of the second connection disk 22 away from the connection sleeve 23. This design enables the connection member 3 to fit tightly on the second connection disk 22, providing additional stability for the entire milk receiving interface device. The horizontal part 32 is bent and extended from the first connection part 33, and its design is intended to provide a stable connection bridge to connect the first connection part 33 with the second connection part 31. The existence of the horizontal part 32 not only enhances the overall structural strength of the connection member 3, but also helps to reduce the risk of loosening or falling off due to vibration or external force. The second connection part 31 is bent and extended from the horizontal part 32, and is designed to be detachably connected to the mounting surface of the first connection disk 12. In addition, this design enables the connection member 3 to be firmly fixed on the first connection disk 12, further enhancing the connection stability between the output tube 1 and the milk receiving tube 2.

[0051] Specifically, when milk needs to be collected, the first tube body 11 of the output tube 1 is first inserted into the accommodating space 24 of the connecting sleeve 23 of the milk collecting tube 2, so that the abutting surface of the first connecting plate 12 is closely fitted with the end surface of the connecting sleeve 23. Then, the first connecting portion 33 of the connecting member 3 is fixed on the second connecting plate 22, and the second connecting portion 31 is connected to the mounting surface of the first connecting plate 12, such as by bolts or other fasteners 4. In this way, the connecting member 3 can reinforce the output tube 1 and the milk collecting tube 2 in multiple directions, ensuring the stability and safety of the entire milk collecting interface device.

[0052] In an optional embodiment, if Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the mounting surface is provided with a mounting hole, the second end of the connector 3 is provided with a through hole, and the fastener 4 is sequentially passed through the through hole and the mounting hole to connect the first connecting plate 12 and the connector 3.

[0053] Specifically, the mounting surface is provided with mounting holes, which can be round holes, square holes or holes of other shapes, and their positions and numbers are determined according to actual needs. The second end of the connector 3, i.e., the second connecting portion 31, is provided with a through hole, which corresponds to the mounting hole and is used to accommodate the fastener 4.

[0054] During the connection process, firstly, the first tube body 11 of the output tube 1 is inserted into the accommodating space 24 of the connecting sleeve 23 of the milk collecting tube 2, so that the abutting surface of the first connecting disk 12 is tightly fitted with the end surface of the connecting sleeve 23. Then, the first connecting portion 33 of the connecting member 3 is fixed on the second connecting disk 22 to ensure a stable connection between the connecting member 3 and the milk collecting tube 2. Next, the fastener 4 (such as a bolt, a pin, etc.) is inserted into the insertion hole of the connecting member 3 and the mounting hole of the first connecting disk 12 in sequence. Through the insertion and fixing of the fastener 4, the second connecting portion 31 of the connecting member 3 and the mounting surface of the first connecting disk 12 are detachably connected, thereby further strengthening the connection stability between the output tube 1 and the milk collecting tube 2.

[0055] It should be noted that this connection method is not only simple and convenient, but also firm and reliable. Since the fastener 4 is used for fixing, the connection between the connecting member 3 and the first connecting plate 12 is not easy to loosen or fall off, which effectively ensures the stability and safety during the milk collection process.

[0056] In an optional embodiment, the second connecting disk 22 is provided with a through hole, the end of the second tube body 21 is arranged in the through hole, and the side of the second connecting disk 22 is provided with an annular groove near the through hole; the milk receiving interface device also includes a second sealing ring, the second sealing ring is arranged in the annular groove, and the end face of the first tube body 11 abuts against the second sealing ring.

[0057] Among them, the design of the second connecting disk 22 takes the sealing performance into special consideration. The second connecting disk 22 is provided with a through hole, and the end of the second tube body 21 is arranged in the through hole, so as to ensure that the milk can flow smoothly from the second tube body 21. In addition, in order to enhance the sealing effect, the side of the second connecting disk 22 is provided with an annular groove near the through hole. The design of the annular groove allows the placement of the second sealing ring, which is placed in the annular groove. When the first tube body 11 of the output tube 1 is inserted into the accommodating space 24 of the connecting sleeve 23, the end face of the first tube body 11 will abut against the second sealing ring. Due to the elasticity of the second sealing ring, it can provide a tight sealing effect when the first tube body 11 is inserted, effectively preventing milk from leaking at the connection.

[0058] In actual application, first ensure that the second sealing ring is correctly placed in the annular groove of the second connecting disk 22. Then, insert the first tube body 11 of the output tube 1 into the accommodating space 24 of the connecting sleeve 23 of the milk collecting tube 2 until the end face of the first tube body 11 abuts against the second sealing ring. At this time, due to the sealing effect of the second sealing ring, the connection between the output tube 1 and the milk collecting tube 2 achieves a good sealing effect. Finally, the first connecting disk 12 and the second connecting disk 22 are reinforced and connected by the connecting member 3. The first connecting portion 33 of the connecting member 3 is fixed on the second connecting disk 22, and the second connecting portion 31 is connected to the mounting surface of the first connecting disk 12 by the fastener 4. In this way, the entire milk collecting interface device achieves a stable and sealed connection.

[0059] In an optional embodiment, the inner wall of the first tube body 11 is aligned with the hole wall of the through hole.

[0060] It should be noted that the advantage of this alignment is that it improves the stability and sealing of the connection. Due to the alignment of the inner wall of the first tube body 11 and the hole wall of the through hole, the gap at the connection between the two is minimized, thereby reducing the possibility of milk leakage.

[0061] In an optional embodiment, the first tube body 11 and the connecting disk are integrally formed, the second tube body 21 and the connecting portion are integrally formed, and the second connecting disk 22 and the connecting sleeve 23 are integrally formed.

[0062] The output tube 1 is formed by integrally molding a first tube body 11 and a first connecting plate 12. This design eliminates the need for an additional connecting structure between the tube body and the connecting plate, thereby enhancing the overall strength and stability. Similarly, the milk collecting tube 2 is also formed by integrally molding a second tube body 21 and a connecting portion, and the connecting portion includes a second connecting plate 22 and a connecting sleeve 23, which are also seamlessly connected.

[0063] It should be noted that the one-piece design not only simplifies the manufacturing process, but also avoids leakage problems caused by loosening or falling off of the connector 3. Since no additional connection structure is required between the components, the structure of the entire device is more compact, reducing potential leakage points and failure points.

[0064] In the embodiment of the utility model, by adopting the one-piece component design, the manufacturing process is simplified, and the overall stability and reliability are improved. At the same time, the device also has the advantages of compact structure, easy operation, good sealing performance, etc., providing a more reliable and efficient solution for dairy product production.

[0065] In order to further enhance the sealing performance between the output tube 1 and the milk collecting tube 2 and effectively prevent leakage of milk, in an optional embodiment, the milk collecting interface device further includes a first sealing ring, which is located between the outer wall of the first tube body 11 and the inner wall of the connecting sleeve 23.

[0066] Specifically, the first sealing ring is designed to be placed between the outer wall of the first tube 11 and the inner wall of the connecting sleeve 23. This design enables the first sealing ring to fit tightly between the first tube 11 and the connecting sleeve 23 to form an effective sealing layer.

[0067] In the specific implementation, first ensure that the first sealing ring is in a proper position, usually by sleeve-fitting the sealing ring on the outer wall of the first tube body 11, or by providing a corresponding sealing groove on the inner wall of the connecting sleeve 23 to fix the sealing ring. Then, the first tube body 11 of the output tube 1 is inserted into the connecting sleeve 23 of the milk collecting tube 2 until the end face of the first tube body 11 abuts against the second sealing ring (as described in the above embodiment). In this process, the first sealing ring is squeezed and deformed, and is tightly fitted between the outer wall of the first tube body 11 and the inner wall of the connecting sleeve 23 to form a seal.

[0068] In the embodiment of the utility model, by introducing the first sealing ring, the sealing performance of the milk collecting interface device is further enhanced, thereby providing a safer and more efficient milk collecting interface device for dairy product production.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
